Methods: Forty anesthesia resident companions who received standardized residency training in our department from July 2018 to July 2020 were randomly divided into an ultrasound group and a control group, with 20 participants in each group. The ultrasound group was taught by ultrasound-guided central venipuncture, while the control group was taught by traditional anatomy. After ten training punctures, all trainees were assessed twice. Results: Both groups could master the technique of central venipuncture. The success rate of first puncture and the overall success rate of puncture in the ultrasound group were significantly higher than those in the control group (p p < 0.05). Conclusion: Compared with the traditional anatomical localization teaching, the use of ultrasound-guided technology can improve the success rate of puncture, save puncture time, reduce related complications, and have a better training effect.展开更多

Various hemostatic compressive devices have been used in subsequent procedures. The objective of this study was to compare the efficacy and safety of a new hemostatic compression device and the widely used TR Band. Methods: A total of 118 patients were divided randomly into two groups: TR Band and the new hemostatic compression device. Efficacy of hemostasis, patient comfort, local vascular dysfunction, and radial artery occlusion(RAO) were evaluated and compared between groups. Results: Occurrence of errhysis or hematoma did not significantly differ between groups(13.6% vs. 11.9%, P = 0.782). Fewer patients had moderate to severe pain or moderate to severe numbness in the new hemostatic compression device group(1.7% vs. 22.0%; 1.7% vs. 18.6%, respectively). Pulse loss between distal artery and device was lower in the new hemostatic compression device group(5.1% vs. 22.0%, P = 0.007), and fewer patients experienced obstruction of venous reflux compared with the TR Band group(6.8% vs. 25.4%, P = 0.006). Combined incidence of RAO at discharge was 7.6%, and was lower in the new hemostatic compression device group(1.7% vs. 13.6%, P = 0.015). In contrast to the TR Band, application of the new hemostatic compression device was independently associated with lower incidence of RAO at discharge(odds ratio: 0.062, 95% confidence interval: 0.006–0.675, P = 0.022). Conclusions: Both the new hemostatic compression device and the TR Band can efficiently achieve hemostasis following transradial coronary catheterization. However, fewer patients felt discomfort with application of the new hemostatic compression device. Pulse loss in the artery distal to the compression device, obstruction of venous reflux, and RAO occurred significantly less often with application of the new device.展开更多

Trans-cholecystic injection of lipopolysaccharide(LPS) was defined as the SAC animal model. Sham operation group, intraperitoneal injection of LPS without BDL group, intraperitoneal injection of LPS with BDL group and trans-cholecystic injection of normal saline with BDL group were defined as control groups. The survival rates and tissue injuries in liver, lungs and kidney were evaluated.RESULTS Mice in the SAC group showed a time-dependent mortality and much more severe tissue injuries in liver, lungs and kidney, compared with other groups. However, relieving biliary obstruction could effectively reduce mortality and attenuate liver injury in the SAC mouse model.CONCLUSION Trans-cholecystic injection of LPS under the condition of biliary obstruction could establish a repeatable and reversible mouse model of SAC.展开更多

Method: 60 cases of VLBWN checked in our hospital’s ICU are selected and divided into combination group (n = 30) and PICC group (n = 30) according to the random number table. Combination of UVC and PICC is applied on newborn of combination group while only PICC is applied on newborn of PICC group. These two groups’ newborn’s PICC catheterization operation time, PICC indwelling time, weight gain, hospital stays, hospital infection, planned extubation, successful single puncture, adverse events and other indexes are observed. Result: Newborns in combination group have less PICC catheterization operation time and less hospital stays than newborns in PICC group while newborns in combination group have longer PICC indwelling time and greater weight gain than newborns in PICC group. The difference here has statistical significance (p < 0.05). Combination group’s hospital infection ratio (3.33%) is lower than that of PICC group (23.33%). The difference here has statistical significance (p < 0.05). Newborns in combination group have a planned extubation rate of 93.33% and a successful single puncture rate of 93.33%, which are greater than those of newborn in PICC group (respectively 73.33% and 70.00%). The difference here has statistical significance (p < 0.05). Newborns in combination group have an adverse event occurrence rate of 43.33%, lower than that of PICC group (70.00%). The difference here has statistical significance (p < 0.05). Conclusion: Application of combination of UVC and PICC on VLBWN can greatly improve PICC catheterization efficiency and newborn patients’ nutriture and reduce rate of complications, thus, it is worthy of clinical application.展开更多

This study aims to compare the success rate of the first attempt, procedure time, operator satisfaction with the used devices, pain score, and complications between intraosseous(IO) access and central venous catheterization(CVC) in critically ill Chinese patients.METHODS: In this prospective clustered randomized controlled trial, eight hospitals were randomly divided into either the IO group or the CVC group. Patients who needed emergency vascular access were included. From April 1, 2017 to December 31, 2018, each center included 12 patients. We recorded the data mentioned above.RESULTS: A total of 96 patients were enrolled in the study. There were no statistically significant differences between the two groups regarding sex, age, body mass index, or operator satisfaction with the used devices. The success rates of the first attempt and the procedure time were statistically significant between the IO group and the CVC group(91.7% vs. 50.0%, P<0.001;52.0 seconds vs. 900.0 seconds, P<0.001). During the study, 32 patients were conscious. There was no statistically significant difference between the two groups regarding the pain score associated with insertion. There were statistically significant differences between the two groups regarding the pain score associated with IO or CVC infusion(1.5 vs. 0.0, P=0.044). Complications were not observed in the two groups.CONCLUSIONS: IO access is a safe, rapid, and effective technique for gaining vascular access in critically ill adults with inaccessible peripheral veins in the emergency departments.展开更多
