Objective:To determine the median effective dose (ED 50) of oliceridine inhibiting responses to insertion of the gastroscope when combined with propofol in obese patients. Methods:In this prospective study, American Society of Anesthesiologists Physical Status classification I or Ⅱ patients of either sex, with a body mass index of ≥28 kg/m 2, undergoing elective painless gastroscopy, were selected. Propofol 1.5 mg/kg was slowly injected intravenously 2 min after intravenous injection of oliceridine. Gastroscopy was performed after the patient′s eyelash reflex disappeared and the jaw was relaxed. The optimal dose was determined by modified Dixon′s up and down method. The initial dose of oliceridine was 0.015 mg/kg, and the ratio between the two successive concentrations was 1.0∶1.2. If the patient had a positive response that affected the examination operation such as swallowing, bucking and body movement during insertion of the gastroscope, the next patient received a higher dose, or conversely if negative, a lower dose was given in the next patient. This process was repeated until the 7th turning point occurred. The ED 50 and 95% confidence interval of olicerdine inhibiting responses to insertion of the gastroscope were calculated by probit method. Results:A total of 21 patients were included in this study, the ED 50 of olicerdine inhibiting responses to implantation of the gastroscope was 0.016 mg/kg, and the 95% confidence interval was 0.010-0.023 mg/kg when combined with propofol 1.5 mg/kg in obese patients. One patient developed hypoxemia. One patient had mild dizziness after operation. Conclusions:The ED 50 of olicerdine inhibiting responses to implantation of the gastroscope is 0.016 mg/kg when combined with propofol 1.5 mg/kg in obese patients.

Objective Exploring the clinical efficacy of using autologous rib cartilage grafting to reconstruct finger hemiarticular defects.Methods From August 2022 to February 2024,for 6 patients with hemiarticular surface defects in the metacarpophalangeal joints and interphalangeal joints of 8 fingers,costal cartilage was used for joint remodeling and transplantation to reconstruct the hemiarticular surface defects of the fingers.All 8 joint transplants in 6 patients were two-stage surgeries.In the first stage,antibiotic bone cement was used to fill the space-occupying lesions,and in the second stage,costal cartilage joint remodeling was performed to reconstruct the finger joint defects.Postoperative follow-up and assessment of fracture healing according to Paley fracture healing scoring criteria.Outpatient and WeChat follow-up,upper limb function is evaluated according to the upper limb functional assessment standards of the Chinese Medical Association Hand Surgery Society.Record VAS pain score.Results In this group,there were a total of 6 patients with 8 cases of hemiarticular defects.Among them,2 patients had two joint surgical sites,while the remaining 4 patients had a single joint surgical site.There were 2 cases of metacarpophalangeal joint head defects,2 cases of proximal articular surface defects,3 cases of proximal articular head defects,and 1 case of thumb proximal articular head defect.After surgery,8 out of 6 patients'hand wounds healed successfully.All patients were followed up for 6-12 months postoperatively,with an average of 9 months.The VAS pain score(affected finger)for the last follow-up was 0-2 points,with an average of 0.6 points.According to Paley's scoring criteria,all 6 patients had excellent fracture healing.According to the evaluation criteria for upper limb functional assessment of the Chinese Medical Association Hand Surgery Society,3 cases were rated as excellent,3 cases were rated as good,and 2 cases were rated as fair.Conclusion For patients with half joint defects on one side of the finger,rib rib cartilage was used for joint reconstruction,which significantly improved the joint shape and function at the defect site,and reduced joint pain scores.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To investigate the best evidence application of exercise prescription in patients with chronic heart failure in clinical practice and evaluate its effectiveness.Methods The best evidence of exercise prescription for patients with chronic heart failure was summarized,and the evidence-based practice plan was developed,and it was implemented in the cardiology department of a tertiary hospital in Zhejiang Province from August to October,2022.Nurses'exercise prescription knowledge-attitude-practice level,implementation rate of review indicators,the length of hospital stay,exercise endurance,daily living ability and grip strength of both groups before and after the intervention were compared.Results After the application of the best evidence,the score of knowledge dimension was(9.34±0.98)points;the score of attitude dimension was(63.29±1.37)points;the score of practice dimension was(25.49±1.51)points,which were statistically significant compared with the scores before the application of evidence(P<0.05).After the application of the best evidence,the implementation rate of 16 review indicators was higher than that before the application of evidence(P<0.001).The length of hospital stay in the evidence application group was shorter than that in the baseline examination group(Z=-2.610,P<0.001).After intervention,the exercise endurance,daily living ability and grip strength of patients in the evidence application group were improved compared with the baseline review group,and the difference was statistically significant(P<0.05).Conclusion After the application of the best evidence of exercise prescription in patients with chronic heart failure,it can improve the level of knowledge,attitude and practice of nurses on exercise prescription,standardize the compliance of nurses'exercise prescription,reduce the number of days in the hospital,and improve patients'exercise endurance,daily living ability and grip strength.
