Among them, stress injury is the main complication of prone spine surgery, but the reasons for stress injury in prone spine surgery are not clear, and whether prone cardiopulmonary resuscitation (CPR) can be used needs to be further verified. Supine cardiopulmonary resuscitation is commonly used in posterior spinal surgery, retroperitoneal surgery, and so on, which can effectively improve the patient’s hypoxemia. Such surgeries require a high level of anesthetic management, and cardiopulmonary resuscitation is necessary if a patient in a prone position experiences cardiac arrest. In the process of cardiopulmonary resuscitation, supine cardiopulmonary resuscitation is often used, especially for some obese patients, if they are immediately changed to the supine position, it takes up more time, there may be wound infection, and there is a possibility of missing the optimal rescue and resuscitation time. Based on this, this paper reviews the use of prone-position cardiopulmonary resuscitation for spinal surgery in the prone position.展开更多

METHODS AKI incidence in children undergoing spinal instru-mentation surgery at British Columbia Children’s Hospital between January 2006 and December 2008 was determined by the Acute Kidney Injury Networ classification using serum creatinine and urine output criteria. During this specific time period, all patients following spinal surgery were monitored in the pediatric intensive care unit and had an indwelling Foley catheter permitting hourly urine output recording. Cases of AKI were identifed from our database. From the remaining cohort, we selected group-matched controls that did not satisfy criteria for AKI. The controls were matched for sex, age and underlying diagnosis （idiopathic vs non-idiopathic scoliosis）. RESULTS Thirty five of 208 patients met criteria for AKI with an incidence of 17% （95%CI： 12%-23%）. Of all children who developed AKI, 17 （49%） developed mild AKI （AKI Stage 1）, 17 （49%） developed moderate AKI （Stage 2） and 1 patient （3%） met criteria for severe AKI （Stage 3）. An inverse relationship was observed with AKI incidence and the amount of fluids received intra-operatively. An inverse relationship was observed with AKI incidence and the amount of fuids received intra-operatively classifed by fluid tertiles： 70% incidence in those that received the least amount of fluids vs 29% that received the most fluids （〉 7.9, P = 0.02）. Patients who developed AKI were more frequently exposed to nephrotoxins （non steroidal anti inflammatory drugs or aminoglycosides） than control patients during their peri-operative course （60% vs 22%, P 〈 0.001）. CONCLUSION We observed a high incidence of AKI following spinal instrumentation surgery in children that is potentially related to the frequent use of nephrotoxins and the amount of fuid administered peri-operatively.展开更多

Objective: The purpose of the present study was to see the outcome of the spinal tumour surgery. Methodology: Patients with spinal tumor have undergone surgery in neurospine unit of National Institute of Neurosciences and Hospital, Dhaka, Bangladesh from May 2013 to March 2015 for a period of 23(twenty three) months. Plain X-ray and MRI were done in all cases. All patients have undergone surgery through posterior midline approach. They were evaluated preoperatively and at discharge usually on 10<sup>th</sup> postoperative day after stitch removal and advised to attend in follow up clinic after 2 months of surgery. Result: 50 - 59 years age group was observed as most vulnerable for tumor occurrence (23 cases, 47.9%). The male female ratio was 1:1.3. The highest number (28 cases, 58.4%) of tumor was observed in thoracic region but the highest variety was schwannoma (33 cases, 68.7%). Initial presentation of patients was pain (32 cases, 66.7%), motor disturbances (9 cases 18.7%), sensory disturbances (5 cases 10.4%) and sphincter disturbances (2 cases 4.2%). Symptomatic improvement was in 44 (91.7%) patients whereas improvement in Frankel Scale was observed in 10 (20.8%) patients during follow up. 4 (8.4%) patients deteriorated and there was no death in this series. Conclusion: In conclusion, majority of the spinal tumour patients are presented with schwannoma with good symptomatic improvement.展开更多

Here we list equipment and reagents,and give a detailed protocol for complete transection of the adult zebrafish spinal cord. In this protocol,potential problems and their solutions are described so that the zebrafish spinal cord injury model can be more easily and reproducibly performed.In addition,two assessments are introduced to monitor the success of the surgery and functional recovery：one test to assess free swimming capability and the other test to assess extent of neuroregeneration by in vivo anterograde axonal tracing.In the swimming behavior test,successful complete spinal cord transection is monitored by the inability of zebrafish to swim freely for 1 week after spinal cord injury,followed by the gradual reacquisition of full locomotor ability within 6 weeks after injury.As a morphometric correlate,anterograde axonal tracing allows the investigator to monitor the ability of regenerated axons to cross the lesion site and increasingly extend into the gray and white matter with time after injury,confirming functional recovery.This zebrafish model provides a paradigm for recovery from spinal cord injury,enabling the identification of pathways and components of neuroregeneration.展开更多

Methods: a total of 100 hospitalized patients in spinal surgery in our hospital were selected, and the research period was from June 2019 to March 2021. Finally, the nursing index data of these patients before and after nursing risk management measures were collected, and the comparative effect and significance between them were analyzed. Results: after the nursing risk control of spinal surgery patients, it was found that all nursing indexes of patients were better than before (P < 0.05). Before the corresponding nursing risk management measures were taken, the nursing quality score of 100 patients was (83.25 ± 2.12), and after the implementation, it was (95.45 ± 3.18). After the implementation, the satisfaction of nursing quality was higher than before (P < 0.05). Conclusion: in the nursing work of spinal surgery, it is necessary to be good at finding possible nursing risks and taking corresponding nursing measures. After the implementation, the nursing risks of spinal surgery are obviously reduced, and the nursing quality of patients is improved, which can be popularized in spinal surgery and even the whole surgical system.展开更多

As this lesion is a spinal cord or central nervous injury functional return depends on spinal cord nerve cell growth within the central nervous system. Basic science, clinical research and human application has demonstrated good and useful motor function after ventral root avulsion followed by spinal cord reimplantation. Recently, sensory return could be demonstrated following spinal cord surgery bypassing the injured primary sensory neuron. Experimental data showed that most of the recovery depended on new growth reinnervating peripheral receptors. Restored sensory function and the return of spinal reflex was demonstrated by electrophysiology and functional magnetic resonance imaging of human cortex. This spinal cord surgery is a unique treatment of central nervous system injury resulting in useful functional return. Further improvements will not depend on surgical improvements. Adjuvant therapy aiming at ameliorating the activity in retinoic acid elements in dorsal root ganglion neurons could be a new therapeutic avenue in restoring spinal cord circuits after nerve root avulsion injury.展开更多
<strong>Objective: </strong>To explore the therapeutic effect of autologous blood reinfusion combined with controlled hypotension in surgical spinal fixation during the outbreak of COVID-19. <strong>...<strong>Objective: </strong>To explore the therapeutic effect of autologous blood reinfusion combined with controlled hypotension in surgical spinal fixation during the outbreak of COVID-19. <strong>Methods: </strong>30 patients with spinal internal fixation autologous blood transfusion combined with controlled hypotension were selected as the subjects during the epidemic period from December 2019 to June 2020 in our hospital and during the operation, on the basis of routine blood pressure reduction, the American Haemonetice Corporation autologous blood continuous reinfusion system was used to infuse the blood recovered during the operation to the patient through filtration and other procedures. <strong>Results:</strong> 30 patients had no complications such as fever and hemolysis;And after the operation, the tube was dialed according to the drainage volume, the cervical thoracic and lumbar brace was customized, and the patient walked on the ground for one week;After no abnormalities, the patient was discharged. Intraoperative comparison of white blood cells (WBC), red blood cells (RBC), red blood cell pressure (HCT), hemoglobin (HGB), and coagulation time (PT) of patients with autologous blood before and after transfusion showed statistically significant differences before and after surgery (P < 0.001). <strong>Conclusion:</strong> During the new coronavirus pneumonia epidemic, the internal fixation of spinal surgery used a recovery machine to collect intraoperative blood for reinfusion. Intraoperative antihypertensive drugs were used to control blood pressure within a certain safe range. The postoperative clinical observation effect was significant and safe;especially at present the clinical significance during the epidemic was significant.展开更多

However, the structure of blood vessels and nerve tissues along the route of anterior cervical surgery is complex. We aimed to measure the data of the longus colli, the sympathetic trunk and the cervical sympathetic trunk （CST） ganglia in Chinese cadaver speci- mens. A total of 32 adult cadavers were studied. We delineated the surgical anatomy of the CST. The superior and inferior/cervicothoracic ganglia of the sympathetic trunk consistently appeared. The middle ganglion was observed in 28.1% of the specimens and there were 2 cases of unilateral double middle cervical ganglia. The inferior ganglion was observed in 25.0% of the specimens and the cervicothoracic ganglion was observed in the remaining speci- mens. The distance between the CST gradually decreased from the top to the bottom, and the distance between the medial edges of the longus colli gradually broadened from the top down. The average angle between the bilat- eral CST and the midline of the vertebra was 11.2°± 1.8° on the left side and 10.3°± 1.4° on the right side. The average angle between the medial margins of longus colli of both sides was 11.1°± 1.9°. The CST is at high risk when LC muscle is cut transversely or is dragged heavily, especially at the levels of C6 and C7. Awareness of the regional anatomy of the CST could help surgeons to identify and preserve it during anterior cervical surgeries.展开更多

The operation is to remove part of vertebral lamina and release the pressure on the spinal nerve. Because many important vessels and nerves are under the vertebral lamina, any incorrect operation may cause irreparable damage to patients. To improve the safety of lamina milling task, a fuzzy force control strategy is proposed in this paper. Primary experiments have been conducted on bone samples from different animals. The results show that, with the fuzzy force control strategy, the bone milling system can recognize all surgery states and halt the tool at the proper location, achieving satisfactory surgery performance.展开更多

Methodology: Patients with spinal tumor have undergone surgery in neurospine unit of National Institute of Neurosciences and Hospital, Dhaka, Bangladesh from May 2013 to March 2015 for a period of 23(twenty three) months. Plain X-ray and MRI were done in all cases. All patients have undergone surgery through posterior midline approach. They were evaluated preoperatively and at discharge usually on 10<sup>th</sup> postoperative day after stitch removal and advised to attend in follow up clinic after 2 months of surgery. Result: 50 - 59 years age group was observed as most vulnerable for tumor occurrence (23 cases, 47.9%). The male female ratio was 1:1.3. The highest number (28 cases, 58.4%) of tumor was observed in thoracic region but the highest variety was schwannoma (33 cases, 68.7%). Initial presentation of patients was pain (32 cases, 66.7%), motor disturbances (9 cases 18.7%), sensory disturbances (5 cases 10.4%) and sphincter disturbances (2 cases 4.2%). Symptomatic improvement was in 44 (91.7%) patients whereas improvement in Frankel Scale was observed in 10 (20.8%) patients during follow up. 4 (8.4%) patients deteriorated and there was no death in this series. Conclusion: In conclusion, majority of the spinal tumour patients are presented with schwannoma with good symptomatic improvement.

文摘Adult zebrafish has a remarkable capability to recover from spinal cord injury,providing an excellent model for studying neuro-regeneration. Here we list equipment and reagents,and give a detailed protocol for complete transection of the adult zebrafish spinal cord. In this protocol,potential problems and their solutions are described so that the zebrafish spinal cord injury model can be more easily and reproducibly performed.In addition,two assessments are introduced to monitor the success of the surgery and functional recovery：one test to assess free swimming capability and the other test to assess extent of neuroregeneration by in vivo anterograde axonal tracing.In the swimming behavior test,successful complete spinal cord transection is monitored by the inability of zebrafish to swim freely for 1 week after spinal cord injury,followed by the gradual reacquisition of full locomotor ability within 6 weeks after injury.As a morphometric correlate,anterograde axonal tracing allows the investigator to monitor the ability of regenerated axons to cross the lesion site and increasingly extend into the gray and white matter with time after injury,confirming functional recovery.This zebrafish model provides a paradigm for recovery from spinal cord injury,enabling the identification of pathways and components of neuroregeneration.

文摘BACKGROUND This is a retrospective study on endoscopic treatment of cervical spinal radiculopathy(CSR)conducted at a single academic institution.Conventional full-spine endoscopy is performed in a single portal which has certain limitations of high technical requirements,steep learning curve,and narrow indications.Although unilateral biportal endoscopy(UBE)technique has a gentle learning curve and is gradually applied to treat CSR,all procedures were performed in the uniportal working channel that potentially increase the surgical risk and time in the treatment of complex cases.It is worthy to delve novel technique for more working channels in the treatment of complex CSR.AIM To propose a hybrid technique(HT)that utilizes spine endoscopy in UBE to treatment of CSR.METHODS A total of 81 patients with single-segment CSR who underwent uniportal endoscopic surgery(UES),UBE,or HT at a single institution between September 2019 and August 2021 were retrospectively studied.Perioperative patient data were compared between the groups.The pre-operative and post-operative images were compared to confirm adequate decompression of the nerve root canal.Patients'visual analogue scale(VAS)scores and neck disability index(NDI)were recorded before surgery,and three days,three months and six months after surgery.RESULTS The UBE and HT groups had a significantly shorter operation duration than the UES group.Data for bleeding and length of hospital stay were significantly higher in the UBE group than in the UES and HT groups.The hospitalization cost was lowest in the UES group and highest in the HT group.Soft tissue edema reaction bands on postoperative day 3 were larger in the UBE and HT groups than in the UES group.Post-operative VAS and NDI scores were significantly lower in all three groups than the pre-operative levels.On post-operative day 3,the VAS score for neck pain was significantly higher in the UBE and HT groups than that in the UES group.However,there were no significant differences in the VAS scores for arm pain or NDI between the three groups.The post-operative 3-month and 6-month neck pain VAS,arm pain VAS,NDI,and modified Macnab success rates did not differ statistically between the three groups.CONCLUSION The HT for CSR treatment has the advantage of double working channels to facilitate decompression and hemostasis,improving the surgical efficiency and clinical outcomes of CSR.
文摘Objective: to study the existing or possible nursing risks of patients in the clinical nursing process of spinal surgery, and to take targeted countermeasures. Methods: a total of 100 hospitalized patients in spinal surgery in our hospital were selected, and the research period was from June 2019 to March 2021. Finally, the nursing index data of these patients before and after nursing risk management measures were collected, and the comparative effect and significance between them were analyzed. Results: after the nursing risk control of spinal surgery patients, it was found that all nursing indexes of patients were better than before (P < 0.05). Before the corresponding nursing risk management measures were taken, the nursing quality score of 100 patients was (83.25 ± 2.12), and after the implementation, it was (95.45 ± 3.18). After the implementation, the satisfaction of nursing quality was higher than before (P < 0.05). Conclusion: in the nursing work of spinal surgery, it is necessary to be good at finding possible nursing risks and taking corresponding nursing measures. After the implementation, the nursing risks of spinal surgery are obviously reduced, and the nursing quality of patients is improved, which can be popularized in spinal surgery and even the whole surgical system.

文摘This mini review describes the current surgical strategy for restoring function after traumatic spinal nerve root avulsion in brachial or lumbosacral plexus injury in man. As this lesion is a spinal cord or central nervous injury functional return depends on spinal cord nerve cell growth within the central nervous system. Basic science, clinical research and human application has demonstrated good and useful motor function after ventral root avulsion followed by spinal cord reimplantation. Recently, sensory return could be demonstrated following spinal cord surgery bypassing the injured primary sensory neuron. Experimental data showed that most of the recovery depended on new growth reinnervating peripheral receptors. Restored sensory function and the return of spinal reflex was demonstrated by electrophysiology and functional magnetic resonance imaging of human cortex. This spinal cord surgery is a unique treatment of central nervous system injury resulting in useful functional return. Further improvements will not depend on surgical improvements. Adjuvant therapy aiming at ameliorating the activity in retinoic acid elements in dorsal root ganglion neurons could be a new therapeutic avenue in restoring spinal cord circuits after nerve root avulsion injury.
文摘<strong>Objective: </strong>To explore the therapeutic effect of autologous blood reinfusion combined with controlled hypotension in surgical spinal fixation during the outbreak of COVID-19. <strong>Methods: </strong>30 patients with spinal internal fixation autologous blood transfusion combined with controlled hypotension were selected as the subjects during the epidemic period from December 2019 to June 2020 in our hospital and during the operation, on the basis of routine blood pressure reduction, the American Haemonetice Corporation autologous blood continuous reinfusion system was used to infuse the blood recovered during the operation to the patient through filtration and other procedures. <strong>Results:</strong> 30 patients had no complications such as fever and hemolysis;And after the operation, the tube was dialed according to the drainage volume, the cervical thoracic and lumbar brace was customized, and the patient walked on the ground for one week;After no abnormalities, the patient was discharged. Intraoperative comparison of white blood cells (WBC), red blood cells (RBC), red blood cell pressure (HCT), hemoglobin (HGB), and coagulation time (PT) of patients with autologous blood before and after transfusion showed statistically significant differences before and after surgery (P < 0.001). <strong>Conclusion:</strong> During the new coronavirus pneumonia epidemic, the internal fixation of spinal surgery used a recovery machine to collect intraoperative blood for reinfusion. Intraoperative antihypertensive drugs were used to control blood pressure within a certain safe range. The postoperative clinical observation effect was significant and safe;especially at present the clinical significance during the epidemic was significant.

文摘Aspirin is widely used for primary or secondary prevention of ischemic events.At the same time,chronic aspirin consumption can affect blood clot formation during surgical intervention and increase intraoperative blood loss.This is especially important for high-risk surgery,including neurosurgery.Current European Society of Cardiology guidelines recommend aspirin interruption for at least 7 d before neurosurgical intervention,but this suggestion is not supported by clinical evidence.This narrative review presents evidence that challenges the necessity for aspirin interruption in neurosurgical patients,describes options for aspirin effect monitoring and the clinical implication of these methods,and summarizes current clinical data on bleeding risk associated with chronic aspirin therapy in neurosurgical patients,including brain tumor surgery,cerebrovascular procedures,and spinal surgery.
文摘BACKGROUND While most complications of cervical surgery are reversible,some,such as symptomatic postoperative spinal epidural hematoma(SEH),which generally occurs within 24 h,are associated with increased morbidity and mortality.Delayed neurological dysfunction is diagnosed in cases when symptoms present>3 d postoperatively.Owing to its rarity,the risk factors for delayed neurological dysfunction are unclear.Consequently,this condition can result in irreversible neurological deficits and serious consequences.In this paper,we present a case of postoperative SEH that developed three days after hematoma evacuation.CASE SUMMARY A 68-year-old man with an American Spinal Injury Association(ASIA)grade C injury was admitted to our hospital with neck pain and tetraplegia following a fall.The C3-C7 posterior laminectomy and the lateral mass screw fixation surgery were performed on the tenth day.Postoperatively,the patient showed no changes in muscle strength or ASIA grade.The patient experienced neck pain and subcutaneous swelling on the third day postoperatively,his muscle strength decreased,and his ASIA score was grade A.Magnetic resonance imaging showed hypointense signals on T1 weighted image(T1WI)and T2WI located behind the epidural space,with spinal cord compression.Emergency surgical intervention for the hematoma was performed 12 h after onset.Although hypoproteinemia and pleural effusion did not improve in the perioperative period,the patient recovered to ASIA grade C on day 30 after surgery,and was transferred to a functional rehabilitation exercise unit.CONCLUSION This case shows that amelioration of low blood albumin and pleural effusion is an important aspect of the perioperative management of cervical surgery.Surgery to relieve the pressure on the spinal cord should be performed as soon as possible to decrease neurological disabilities.

文摘Anterior cervical surgery is commonly used for cervical vertebral body lesions. However, the structure of blood vessels and nerve tissues along the route of anterior cervical surgery is complex. We aimed to measure the data of the longus colli, the sympathetic trunk and the cervical sympathetic trunk （CST） ganglia in Chinese cadaver speci- mens. A total of 32 adult cadavers were studied. We delineated the surgical anatomy of the CST. The superior and inferior/cervicothoracic ganglia of the sympathetic trunk consistently appeared. The middle ganglion was observed in 28.1% of the specimens and there were 2 cases of unilateral double middle cervical ganglia. The inferior ganglion was observed in 25.0% of the specimens and the cervicothoracic ganglion was observed in the remaining speci- mens. The distance between the CST gradually decreased from the top to the bottom, and the distance between the medial edges of the longus colli gradually broadened from the top down. The average angle between the bilat- eral CST and the midline of the vertebra was 11.2°± 1.8° on the left side and 10.3°± 1.4° on the right side. The average angle between the medial margins of longus colli of both sides was 11.1°± 1.9°. The CST is at high risk when LC muscle is cut transversely or is dragged heavily, especially at the levels of C6 and C7. Awareness of the regional anatomy of the CST could help surgeons to identify and preserve it during anterior cervical surgeries.
文摘Vertebral lamina milling task is one of the high-risk operations in spinal surgeries. The operation is to remove part of vertebral lamina and release the pressure on the spinal nerve. Because many important vessels and nerves are under the vertebral lamina, any incorrect operation may cause irreparable damage to patients. To improve the safety of lamina milling task, a fuzzy force control strategy is proposed in this paper. Primary experiments have been conducted on bone samples from different animals. The results show that, with the fuzzy force control strategy, the bone milling system can recognize all surgery states and halt the tool at the proper location, achieving satisfactory surgery performance.
