We compared its analgesic efficacy with thoracic epidural block for upper abdominal cancer surgeries. Methods: This prospective study included 60 patients, 18 to 65 years old with ASA class II who underwent gastrectomy and Whipple’s procedures under general anesthesia. Patients were assigned into two groups: Thoracic epidural group, with injection of 0.1 ml/kg of bupivacaine 0.25% in epidural catheter followed by 0.1 ml/kg/h of 0.125% bupivacaine infusion for 48 hrs., and Erector spinae group, with insertion of bilateral erector spinae catheters to inject 0.1 ml/kg of bupivacaine 0.25% followed by bilateral infusion of 0.1 ml/kg/h of bupivacaine 0.125% for 48 hrs. The primary endpoint was postoperative VAS scores at rest and movement. Secondary endpoint included postoperative total opioid consumption, 1st request for analgesia, hemodynamic changes and satisfaction scores. Results: Pain scores and needed rescue analgesia in both groups were comparable. However, 1st request for opioid was significantly longer in TEPI compared to ESI group. Hemodynamics were significantly lower in TEPI group with no differences in the incidence of postoperative complications except for hypotension. Patient satisfaction scores were arbitrarily higher in ESI group without significance. Conclusion: Erector spinae infusion is a highly promising regional technique with comparable effects to thoracic epidural blockade in reducing pain and opioid needs while causing minimal hemodynamic consequences.展开更多

A rare complication of this technique is epidural catheter retention. Case Presentation: In this case report, we present an otherwise healthy 21-year-old G2P0010 woman at 39 weeks and 3 days gestation whose anesthetic management was complicated by a symptomatic retained epidural catheter fragment. Computed tomography (CT) imaging of her spine showed the fractured catheter within her paraspinal muscles and neurosurgery recommended no surgical intervention at that time. The patient reported resolution of back pain while in the postpartum unit which she continues to endorse two weeks after discharge. Conclusion: Retained epidural catheter is a medical emergency that requires immediate imaging and neurological evaluation. While magnetic resonance imaging is typically regarded as the standard imaging modality for this complication, in epidural sets that contain metallic components, we suggest using CT to avoid the risk of thermal nerve damage. In cases where the patient does not report any acute complaints, nonsurgical management may be appropriate but close follow-up is required to monitor for catheter migration.展开更多

The structured epidural teaching model (SETM) includes three standardized video lessons, the construction of a 3D epidural module by trainees and practical training by using an epidural simulator with and without the CompuFlo™ Epidural instrument. In this study we report the retrospective analysis of the accidental dural puncture rate of inexperienced trainees during their 6 months clinical practice rotation in obstetrics before and after the introduction of the SETM in our Institution. Method: We evaluated the incidence of accidental dural puncture before the introduction of the SETM methodology and afterwards by analyzing our departmental database from February 2019 to January 2023. All epidural blocks were executed by trainees who had never previously performed an epidural block and were about to begin their obstetrics rotation. Results: We analyzed 7415 epidurals: 3703 were performed before the introduction of the SETM methodology (control group) and 3712 afterwards (study group). The incidence of accidental dural puncture was 0.37% for the control group and 0.13% for the study group (p<.05). The probability of making an accidental dural puncture was 64% (OR: 0.36) lower for trainees who had the training than for those who did not. Conclusions: After the introduction of the structured teaching method, we observed a significant reduction of accidental dural puncture during the training period. We hope that our observation will encourage a constructive discussion among experts about the need to use standardized and validated tools as a valuable aid in teaching epidural anesthesia.展开更多

A catheter-assisted interlaminar Cervical Epidural Steroid Injection (CESI) was performed under fluoroscopic guidance, targeting the affected C2-C6 levels. Significant improvement was observed after this procedure, with decreased pain scores (visual analogue scale (VAS) 8 to 2) and improved mobility. This technique not only enhances the effectiveness of CESI but also reduces the likelihood of complications such as stroke or epidural hematoma and thus provides an alternative treatment option for patients with multiple stenotic levels who are unsuitable for surgery or are unresponsive to conservative therapy such as medication or physical therapy.展开更多

文摘Objective:To analyze the effects of combined spinal-epidural anesthesia and epidural anesthesia in patients undergoing appendicitis surgery.Methods:Seventy-eight patients who underwent surgical treatment for appendicitis from February 2022 to February 2025 were selected as samples and randomly divided into two groups.The study group received combined spinal-epidural anesthesia,while the control group received epidural anesthesia.Anesthesia indicators,vital signs,and complication indicators were compared between the two groups.Results:The onset time of anesthesia in the study group was shorter than that in the control group,the visual analog scale(VAS)score was lower than that in the control group,and the highest plane of anesthesia block was lower than that in the control group(P<0.05).At 15 minutes after anesthesia induction and at the end of surgery,the heart rate(HR),mean arterial pressure(MAP),and blood oxygen saturation(SPO2)in the study group were significantly different from those in the control group(P<0.05).The complication rate in the study group was lower than that in the control group(P<0.05).Conclusion:Combined spinal-epidural anesthesia for appendicitis surgery can reduce the impact of anesthesia on vital signs,shorten the onset time of anesthesia,and is highly effective and feasible.
文摘BACKGROUND Chest physiotherapy and incentive spirometry,essential for pulmonary care,can exacerbate acute post-thoracotomy pain.Pain relief is,therefore,essential to facilitate early mobilization.This study evaluated the analgesic efficacy of unilateral continuous erector spinae block(ESB)compared to thoracic epidural analgesia(TEA)in terms of quality of pain relief and perioperative hemodynamic changes.AIM To compare the analgesic efficacy of continuous ultrasound-guided unilateral ESB and thoracic epidural in patients undergoing antero-lateral thoracotomy.METHODS This prospective,observational study was conducted at a tertiary care hospital of central India.Sixty-eight adult patients of either gender,posted for elective thoracic surgeries requiring one lung ventilation,were allocated to either TEA(n=34)or ESB(n=34)group,based on the attending anesthesiologist’s expertise.Continuous data were analyzed by independent t-tests,and categorical data byχ2 tests.RESULTS The proportion of patients requiring rescue opioids within 24 hours post-extubation was similar between the two group.Resting numerical rating scale scores(0 hour,6 hours,and 72 hours post-extubation)were significantly higher in the ESB group compared to the TEA group[1.70±1.03 vs 1.05±0.77(P=0.004);1.64±0.98 vs 1.2±0.88(P=0.05);3.2±1.07 vs 2.61±0.92(P=0.013)].Dynamic numerical rating scale scores and post-extubation mean arterial pressures were also higher in the ESB group.Additionally,block performance time was significantly longer in the ESB group(16.58±3.66 vs 13.84±2.88,P=0.001).CONCLUSION The two techniques provided similar opioid-sparing effects following antero-lateral thoracotomy,though TEA exhibited a superior analgesic efficacy at the expense of increased hemodynamic instability requiring vasopressor support.
文摘BACKGROUND Mesenchymal stem cells(MSCs)are promising candidates for regenerative therapy due to their self-renewal capability,multilineage differentiation potential,and immunomodulatory effects.The molecular characteristics of MSCs are influenced by their location.Recently,epidural fat(EF)and EF-derived MSCs(EF-MSCs)have garnered attention due to their potential benefits to the spinal microenvironment and their high expression of neural SC markers.However,their clinical applications are limited due to cell senescence and limited accessibility of EF.Although many studies have attempted to establish an immortalized,stable SC line,the characteristics of immortalized EF-MSCs remain to be clarified.AIM To establish and analyze stable immortalized EF-MSCs.METHODS The phenotypes of EF-MSCs were analyzed using optical microscopy.Cell immortalization was performed using lentiviral vectors.The biomolecular characteristics of the cells were analyzed by immunoblotting,quantitative PCR,and proteomics.RESULTS The immortalized EF-MSCs demonstrated a significantly extended lifespan compared to the control group,with well-preserved adipogenic potential and SC surface marker expression.Introduction of human telomerase reverse transcriptase genes markedly increased the lifespan of EF-MSCs.Proteomics analysis revealed substantial increase in the expression of DNA replication pathway components in immortalized EF-MSCs.CONCLUSION Immortalized EF-MSCs exhibited significantly enhanced proliferative capacity,retained adipogenic potential,and upregulated the expression of DNA replication pathway components.
文摘BACKGROUND An epidural abscess is a rare but serious medical condition where a pocket of pus forms in the epidural space—the area between the outer covering of the spinal cord(the dura mater)and the bones of the spine.It’s usually caused by a bacterial infection,most commonly Staphylococcus aureus.The infection can spread to this area from other parts of the body,through the bloodstream,or it may be intro-duced directly during spinal procedures like epidural injections or surgery.Symptoms often include severe back pain,fever,and neurological deficits like weakness or numbness,which can progress quickly if untreated.It's considered a medical emergency because if the abscess compresses the spinal cord,it can lead to permanent paralysis or even death.Treatment usually involves antibiotics and,in many cases,surgical drainage.CASE SUMMARY Spinal epidural abscess(SEA)represents a rare yet potentially severe infection affecting the epidural space.We present the following case of a 54-year-old Hispanic white male who initially presented to the emergency department with acute deteriorating symptoms of bilateral lower extremity weakness,which subsequently progressed to involve the upper extremities.However,further evaluation uncovered additional notable symptoms,including urinary inconti-nence and decreased appetite.Further investigation broadened the differential diagnosis,including meningitis,spinal cord compression,acute pyelonephritis,osteomyelitis,bacteremia,torticollis,and acutely progressive ascending bilateral lower extremity weakness,raising the concern for possible Guillain-Barre syndrome.Diagnostic imaging,including magnetic resonance imaging of the spine,confirmed the presence of C5-C6 osteomyelitis and a C6-C7 spinal epidural abscess with severe canal narrowing.The patient underwent an emergency evacuation of epidural abscess with a C6 corpectomy and C5-C7 cervical fusion,followed by an 8-week course of intravenous antibiotics.Cultures from the abscess and bone revealed Staphylococcal aureus.The patient was discharged after 54 days with significant improvement in power and function.CONCLUSION This case highlights the importance of maintaining a high index of suspicion for SEA in patients presenting with atypical symptoms,even in the setting of seemingly unrelated conditions.Early recognition and prompt intervention are crucial to prevent permanent neurological deficits and improve outcomes in patients with SEA.
文摘Objective: Erector spinae plane block is a novel regional anaesthetic intervention that is said to have an effective analgesic profile in the upper abdominal region. We compared its analgesic efficacy with thoracic epidural block for upper abdominal cancer surgeries. Methods: This prospective study included 60 patients, 18 to 65 years old with ASA class II who underwent gastrectomy and Whipple’s procedures under general anesthesia. Patients were assigned into two groups: Thoracic epidural group, with injection of 0.1 ml/kg of bupivacaine 0.25% in epidural catheter followed by 0.1 ml/kg/h of 0.125% bupivacaine infusion for 48 hrs., and Erector spinae group, with insertion of bilateral erector spinae catheters to inject 0.1 ml/kg of bupivacaine 0.25% followed by bilateral infusion of 0.1 ml/kg/h of bupivacaine 0.125% for 48 hrs. The primary endpoint was postoperative VAS scores at rest and movement. Secondary endpoint included postoperative total opioid consumption, 1st request for analgesia, hemodynamic changes and satisfaction scores. Results: Pain scores and needed rescue analgesia in both groups were comparable. However, 1st request for opioid was significantly longer in TEPI compared to ESI group. Hemodynamics were significantly lower in TEPI group with no differences in the incidence of postoperative complications except for hypotension. Patient satisfaction scores were arbitrarily higher in ESI group without significance. Conclusion: Erector spinae infusion is a highly promising regional technique with comparable effects to thoracic epidural blockade in reducing pain and opioid needs while causing minimal hemodynamic consequences.
文摘Thoracic epidural anesthesia(TEA)has been the gold standard of perioperative analgesia in various abdominal and thoracic surgeries.However,misplaced or displaced catheters,along with other factors such as technical challenges,equipment failure,and anatomic variation,lead to a high incidence of unsatisfactory analgesia.This article aims to assess the different sources of TEA failure and strategies to validate the location of thoracic epidural catheters.A literature search of PubMed,Medline,Science Direct,and Google Scholar was done.The search results were limited to randomized controlled trials.Literature suggests techniques such as electrophysiological stimulation,epidural waveform monitoring,and x-ray epidurography for identifying thoracic epidural placement,but there is no one particular superior confirmation method;clinicians are advised to select techniques that are practical and suitable for their patients and practice environment to maximize success.
文摘BACKGROUND Epidural analgesia is the most effective analgesic method during labor.Butorphanol administered epidurally has been shown to be a successful analgesic method during labor.However,no comprehensive study has examined the safety and efficacy of using butorphanol as an epidural analgesic during labor.AIM To assess butorphanol's safety and efficacy for epidural labor analgesia.METHODS The PubMed,Cochrane Library,EMBASE,Web of Science,China National Knowledge Infrastructure,and Google Scholar databases will be searched from inception.Other types of literature,such as conference abstracts and references to pertinent reviews,will also be reviewed.We will include randomized controlled trials comparing butorphanol with other opioids combined with local anesthetics for epidural analgesia during labor.There will be no language restrictions.The primary outcomes will include the visual analog scale score for the first stage of labor,fetal effects,and Apgar score.Two independent reviewers will evaluate the full texts,extract data,and assess the risk of bias.Publication bias will be evaluated using Egger's or Begg's tests as well as visual analysis of a funnel plot,and heterogeneity will be evaluated using the Cochran Q test,P values,and I2 values.Meta-analysis,subgroup analysis,and sensitivity analysis will be performed using RevMan software version 5.4.This protocol was developed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses(PRISMA)Protocols statement,and the PRISMA statement will be used for the systematic review.RESULTS This study provides reliable information regarding the safety and efficacy of using butorphanol as an epidural analgesic during labor.CONCLUSION To support clinical practice and development,this study provides evidence-based findings regarding the safety and efficacy of using butorphanol as an epidural analgesic during labor.

文摘BACKGROUND Uterine fibroids are common benign gynecological conditions.Patients who experience excessive menstruation,anemia,and pressure symptoms should be administered medication,and severe cases require a total hysterectomy.This procedure is invasive and causes severe postoperative pain,which can affect the patient’s postoperative sleep quality and,thus,the recovery process.AIM To evaluate use of dezocine in patient-controlled epidural analgesia(PCEA)for postoperative pain management in patients undergoing total myomectomy.METHODS We selected 100 patients undergoing total abdominal hysterectomy for uterine fibroids and randomized them into two groups:A control group receiving 0.2%ropivacaine plus 0.06 mg/mL of morphine and an observation group receiving 0.2%ropivacaine plus 0.3 mg/mL of diazoxide in their PCEA.Outcomes assessed included pain levels,sedation,recovery indices,PCEA usage,stress factors,and sleep quality.RESULTS The observation group showed lower visual analog scale scores,shorter postoperative recovery indices,fewer mean PCEA compressions,lower cortisol and blood glucose levels,and better polysomnographic parameters compared to the control group(P<0.05).The cumulative incidence of adverse reactions was lower in the observation group than in the control group(P<0.05).CONCLUSION Dezocine PCEA can effectively control the pain associated with total myomectomy,reduce the negative impact of stress factors,and have less impact on patients’sleep,consequently resulting in fewer adverse effects.
文摘Dear Editor,We present a case of dacryocystitis and canaliculitis secondary to residual of epidural catheter remaining in lacrimal duct for 25y.A 56-year-old male patient was admitted to our medical center on February 16,2023.We obtained the written informed consent from the patient,and this case study was in accordance with the tenets of the Declaration of Helsinki.The main complaint was that the right eye had suffered from persistent tears for more than 25y and discharge for more than 1y.
文摘In this editorial,we provide a critical review of the article by Tang et al published in the World J Clin Cases,focusing on the utilization of butorphanol for epidural analgesia during labor.Our discussion encompasses recent research developments in epidural labor analgesia,specifically highlighting the current status of clinical applications of butorphanol and associated treatment approaches.Epidural analgesia is widely acknowledged as the primary method for pain management during labor,offering effective and prolonged pain relief while allowing mothers to remain alert and actively participate in the delivery process.Among the various drugs utilized for epidural labor analgesia,butorphanol has received increasing attention due to its potential efficacy and distinctive pharmacological properties.As a synthetic opioid analgesic,butorphanol exhibits both agonistic and antagonistic activity on opioid receptors,striking a balance between analgesia and minimizing side effects.Nevertheless,the safety and efficacy of butorphanol in epidural labor analgesia remains controversial.While certain studies have reported positive outcomes with butorphanol,including effective pain relief and a reduced incidence of side effects,others have raised concerns about its safety and efficacy compared to traditional opioids or alternative analgesics.In addition,the optimal dosing strategy and regimen of butorphanol as an adjuvant in epidural labor analgesia still need to be verified.Through comprehensive synthesis and analysis of existing literature,we aim to evaluate the current evidence regarding the use of butorphanol for epidural labor analgesia,delineate areas of consensus and controversy,and propose future avenues for research and clinical practice in this domain.
文摘BACKGROUND Combined spinal-epidural(CSE)anesthesia is the preferred anesthesia method for cesarean delivery.The use of an epidural catheter is essential for administering additional drugs intraoperatively and managing postoperative pain.However,the insertion of epidural catheters is associated with various complications,such as total spinal anesthesia,symptoms indicative of spinal nerve root irritation,and challenges in epidural catheter removal.CASE SUMMARY We present a case report of a challenging epidural catheter removal due to knotting.The lumbar computed tomography scan results revealed that the catheter formed a tight knot in the epidural space.We used a novel extubation method and successfully removed the catheter.CONCLUSION The operator can use opposite forces to"spiral"apart the spinal joints by positioning the patient's body in a specific position.The findings indicate that,when combined with imaging examination results,this method is effective for the removal of epidural catheters.
文摘Background: Epidural anesthesia is an effective intervention to treat labor pain and provide analgesia for orthopedic procedures. A rare complication of this technique is epidural catheter retention. Case Presentation: In this case report, we present an otherwise healthy 21-year-old G2P0010 woman at 39 weeks and 3 days gestation whose anesthetic management was complicated by a symptomatic retained epidural catheter fragment. Computed tomography (CT) imaging of her spine showed the fractured catheter within her paraspinal muscles and neurosurgery recommended no surgical intervention at that time. The patient reported resolution of back pain while in the postpartum unit which she continues to endorse two weeks after discharge. Conclusion: Retained epidural catheter is a medical emergency that requires immediate imaging and neurological evaluation. While magnetic resonance imaging is typically regarded as the standard imaging modality for this complication, in epidural sets that contain metallic components, we suggest using CT to avoid the risk of thermal nerve damage. In cases where the patient does not report any acute complaints, nonsurgical management may be appropriate but close follow-up is required to monitor for catheter migration.
文摘Background: The rate of accidental dural puncture is particularly high during the period of training, especially in novices. The structured epidural teaching model (SETM) includes three standardized video lessons, the construction of a 3D epidural module by trainees and practical training by using an epidural simulator with and without the CompuFlo™ Epidural instrument. In this study we report the retrospective analysis of the accidental dural puncture rate of inexperienced trainees during their 6 months clinical practice rotation in obstetrics before and after the introduction of the SETM in our Institution. Method: We evaluated the incidence of accidental dural puncture before the introduction of the SETM methodology and afterwards by analyzing our departmental database from February 2019 to January 2023. All epidural blocks were executed by trainees who had never previously performed an epidural block and were about to begin their obstetrics rotation. Results: We analyzed 7415 epidurals: 3703 were performed before the introduction of the SETM methodology (control group) and 3712 afterwards (study group). The incidence of accidental dural puncture was 0.37% for the control group and 0.13% for the study group (p<.05). The probability of making an accidental dural puncture was 64% (OR: 0.36) lower for trainees who had the training than for those who did not. Conclusions: After the introduction of the structured teaching method, we observed a significant reduction of accidental dural puncture during the training period. We hope that our observation will encourage a constructive discussion among experts about the need to use standardized and validated tools as a valuable aid in teaching epidural anesthesia.

文摘Objective:To observe the analgesic effect of combined spinal and epidural anesthesia on older patients undergoing hip fracture surgery.Method:One hundred and twenty elderly hip fracture surgery patients treated in our hospital from January 2021 to December 2022 were selected and randomly divided into two groups,with 60 cases in the experimental group and 60 in the control group.The experimental group was given combined spinal-epidural anesthesia intervention measures,while the control group was given epidural anesthesia intervention measures.The analgesic effect,tumor necrosis factor-alpha(TNF-α),C-reactive protein(CRP)levels,and other observation indicators were analyzed after anesthesia intervention.Result:After the intervention,the analgesic effect and the evaluation results of the subjects in the experimental group were better than those in the control group(P<0.05);the obtained values of TNF-αand CRP levels in the experimental group were higher than those of the control group(P<0.05).Conclusion:The combined spinal-epidural anesthesia intervention demonstrated positive outcomes.The analgesic effect of patients during surgery and their inflammatory factor levels improved,which makes this intervention worthy of clinical application and promotion.
文摘We present the case of a 64-year-old man with cervical ossification of the posterior longitudinal ligament (OPLL) experiencing chronic neck pain and radiculopathy for 6 months. A catheter-assisted interlaminar Cervical Epidural Steroid Injection (CESI) was performed under fluoroscopic guidance, targeting the affected C2-C6 levels. Significant improvement was observed after this procedure, with decreased pain scores (visual analogue scale (VAS) 8 to 2) and improved mobility. This technique not only enhances the effectiveness of CESI but also reduces the likelihood of complications such as stroke or epidural hematoma and thus provides an alternative treatment option for patients with multiple stenotic levels who are unsuitable for surgery or are unresponsive to conservative therapy such as medication or physical therapy.

文摘BACKGROUND Repeat cesarean deliverys involve a longer surgery and more severe visceral traction than primary cesarean deliverys.The dural puncture epidural(DPE)technique provides faster and more effective analgesia for labor,but there is no sufficient evidence to indicate whether it is suitable for parturients undergoing repeat cesarean delivery.AIM To determine the efficacy and safety of the DPE anesthesia technique in patients undergoing repeat cesarean delivery.METHODS Patients undergoing repeat cesarean delivery were randomly divided into the DPE and epidural anesthesia(EA)groups.A 25-G spinal needle was used for dural puncture via a 19-G epidural needle.The patients in the two groups were injected with 5 mL of 2%lidocaine followed by 15 mL of a mixture of 1%lidocaine+0.5%ropivacaine as the epidural dosage.The primary outcome was the onset time of sensory block to the T6 dermatome level and the sensory and motor block degree.RESULTS A total of 115 women were included(EA:57,DPE:58).The mean time to sensory block to the T6 Level was significantly shorter in the DPE group than in the EA group(14.7 min vs 16.6 min;95%confidence interval,13.9 to 15.4 vs 15.8 to 17.4;P=0.001).The cranial sensory block level was significantly higher at 5,10,and 15 min after the initial dose in the DPE group than in the EA group(P<0.05).The sacral sensory block level was significantly higher and the modified bromage score was significantly lower in the DPE group at each time point(P<0.05).Adverse effects and neonatal outcomes were comparable between the two groups(P>0.05).CONCLUSION The DPE technique provided higher-quality anesthesia than the EA technique,with a rapid onset of surgical anesthesia,better cranial and sacral sensory block spread and a higher motor block degree,without increasing the incidence of maternal or fetal side effects in patients undergoing repeat cesarean delivery.

文摘BACKGROUND Supra-and infratentorial acute epidural hematoma(SIEDH)is a common posterior cranial fossa epidural hematoma located at the inner surface of the squamous part of the occipital bone(SOB).Traditionally,surgical treatment of the SIEDH requires a combined supra-infratentorial craniotomy.AIM To analyze the morphological characteristics of the SOB and introduce a single supratentorial craniotomy for SIEDH.METHODS Skull computed tomography(CT)scan data from 32 adult patients were collected from January 1,2019 to January 31,2020.On the median sagittal plane of the CT scan,the angle of the SOB(ASOB)was defined by two lines:Line A was defined from the lambdoid suture(LambS)to the external occipital protuberance(EOP),while line B was defined from the EOP to the posterior edge of the foramen magnum(poFM).The operative angle for the SIEDH(OAS)from the supra-to infratentorial epidural space was determined by two lines:The first line passes from the midpoint between the EOP and the LambS to the poFM,while the second line passes from the EOP to the poFM.The ASOB and OAS were measured and analyzed.RESULTS Based on the anatomical study,a single supratentorial craniotomy was performed in 8 patients with SIEDH.The procedure and the results of the modified surgical method were demonstrated in detail.For males,the ASOB was 118.4±4.7 and the OAS was 15.1±1.8;for females,the ASOB was 130.4±5.1 and the OAS was 12.8±2.0.There were significant differences between males and females both in ASOB and OAS.The smaller the ASOB was,the larger the OAS was.The bone flaps in 8 patients were designed above the transverse sinus intraoperatively,and the SIEDH was completely removed without suboccipital craniotomy.The SOB does not present as a single straight plane but bends at an angle around the EOP and the superior nuchal lines.The OAS was negatively correlated with the ASOB.CONCLUSION The single supratentorial craniotomy for SIEDH is reliable and effective.
文摘BACKGROUND For parturients with paroxysmal uterine contraction pain,rapid analgesia is needed.We used preprocedure ultrasound imaging combined with the palpation technique in epidural analgesia for labor,and evaluated the usefulness of this technique in epidural labor analgesia.AIM To evaluate the usefulness of preprocedure ultrasound imaging in epidural analgesia for labor.METHODS In this prospective randomized observational study,72 parturients were assigned to two groups(combined or palpation group).The target interspace of all parturients was first identified by the palpation technique.Then in the combined group,preprocedure ultrasound imaging was used before epidural puncture.In the palpation group,only the traditional anatomical landmarks technique(palpation technique)was performed.The primary outcome was total duration of the epidural procedure(for the ultrasound group,the duration of the preprocedure ultrasound imaging was included).The secondary outcomes were the number of skin punctures,the success rate at first needle pass,the number of needle passes,the depth from the skin to epidural space,and the complications of the procedure.RESULTS Total duration of the epidural procedure was similar between the two groups(406.5±92.15 s in the combined group and 380.03±128.2 s in the palpation group;P=0.318).A significant improvement was demonstrated for epidural puncture and catheterization in the combined group.The number of needle passes was 1.14 in the combined group and 1.72 in the palpation group(P=0.001).The number of skin puncture sites was 1.20 in the combined group and 1.25 in the palpation group(P=0.398).The success rate at first needle pass was 88.89%in the combined group and 66.67%in the palpation group(P=0.045).CONCLUSION This study demonstrated that the total duration of epidural procedures with preprocedure ultrasound imaging combined with the palpation technique was not longer than the traditional anatomical landmarks technique,which were performed by six experienced anesthesiologists in parturients with normal weights undergoing labor analgesia.
文摘BACKGROUND Epidural hematoma is one of the common postoperative complications after craniotomy.However,multiple remote epidural hematomas in different sites,including supratentorial and infratentorial regions,are exceedingly rare.CASE SUMMARY We present a rare case in which three remote epidural hematomas occurred after craniotomy.A 21-year-old woman was admitted with a headache for 1 mo,vomiting,and rapid vision loss for 1 wk.Brian magnetic resonance imaging indicated a right thalamic tumor.The intraoperative diagnosis was a cystic tumor,posterior cerebral artery aneurysm,and vascular malformation.The operation was successful.Unfortunately,the patient developed three extradural hematomas within 48 h.Family members consented to the first two hematoma evacuations but refused the third.CONCLUSION More attention should be paid to this kind of rare complication.Adequate preoperative evaluation is important,especially for acute patients.Monitoring neural function and early computed tomography scanning of the brain after surgery should be highlighted.
