双股自制止血带用于三次剖宫产产妇预防产后出血的效果

目的：分析双股自制止血带用于三次剖宫产产妇预防产后出血（PPH）的效果。方法：选取2020年1月至2022年12月上饶市妇幼保健院收治的80例三次剖宫产产妇为研究对象,采用随机数字表法分为观察组与对照组,各40例。两组均在子宫下段剖宫产取出胎儿后采用缩宫素+麦角新碱注射液宫体注射治疗,观察组在此基础上加用双股自制止血带止血。比较两组产妇术中、术后24 h出血量、产后宫底下降速度与恶露持续时间。结果：观察组产妇术中、术后24 h出血量均少于对照组,差异具有统计学意义（P <0.05）;观察组产妇产后宫底下降速度快于对照组,产后恶露持续时间短于对照组,差异具有统计学意义（P <0.05）。结论：双股自制止血带应用于三次剖宫产产妇可有效减少术中、术后出血量,促进产妇产后康复。     

Interface pressure,perceptual, and mean arterial pressure responses to different blood flow restriction systems

This study examined the cuff to limb interface pressure during blood flow restriction (BFR ), and the perceptual and mean arterial pressure responses, in different BFR systems. Eighteen participants attended three experimental sessions in a randomised, crossover, counterbalanced design. Participants underwent inflations at 40% and 80% limb occlusive pressure (LOP ) at rest and completed 4 sets of unilateral leg press exercise at 30% of one repetition maximum with BFR at 80% LOP . Different BFR systems were used each session: an automatic rapid‐inflation (RI ), automatic personalized tourniquet (PT ) and manual handheld pump and sphygmomanometer (HS ) system. Interface pressure was measured using a universal interface device with pressure sensors. Perceived exertion and pain were measured after each set, mean arterial pressure (MAP ) was measured pre‐, 1‐minute post‐ and 5‐minutes post‐exercise. Interface pressure was lower than the set pressure in all BFR systems at rest (P  <  .05). Interface pressure was, on average, 10 ± 8 and 48 ± 36 mm Hg higher than the set pressure in the RI and HS system (P  <  .01), with no differences observed in the PT system (P  >  .05), during exercise. Pain and exertion were greater in sets 3 and 4 in the RI and HS system compared to the PT system (P  <  .05). MAP was higher in the RI and HS system compared to the PT system at 1‐minute and 5‐minutes post‐exercise (P  <  .05). BFR systems applying higher pressures amplify mean arterial pressure and perceptual responses. Automatic BFR systems appear to regulate pressure effectively within an acceptable range during BFR exercise.     

Survey of current cementing techniques in total knee replacement

Background: Current techniques in total knee replacement (TKR) vary greatly. Cementing techniques in TKR are no exception. Identification of current trends would aid ongoing research into future developments. Methods: A questionnaire was sent to all orthopaedic surgeons in Queensland, Australia. A range of factors influencing cementing techniques for the tibial plateau were investigated. Results: Eighty‐five percent of questionnaires were returned. Ninety‐one percent of surgeons regularly cement the tibial plateau, 90% use some form of lavage prior to cement application, 95% of surgeons apply cement by hand only. Techniques aimed at increasing cement penetration (cement gun, intraosseous suction) are used infrequently. Conclusions: In contrast to total hip replacement, measures are not often taken to ensure that there is penetration of cement or a complete cement mantle into the tibial plateau in TKR. This may be because of a perceived lack of evidence in modern literature. This study also illustrates the wide variation in technique in a relatively common orthopaedic operation.     

烧伤休克期一次上止血带削痂的临床应用

目的探讨烧伤休克期采用一次上止血带削痂手术方式的应用。方法A组(25例)为休克期采用一次上止血带削痂的病例,B组(32例)为自1995年以来随机抽取的休克期后采用传统操作方法的病例,对比两者之间手术时间、出血量及并发症率。结果A组手术时间比B组减少了38%(P<0.01),出血量比B组减少了66%(P<0.01),并发症发生率减少了38%。结论烧伤休克期采用一次上止血带削痂方法,可缩短手术时间,减少出血量,减轻对机体的打击,使休克期手术能平稳渡过,使休克期手术能在临床广泛应用。     

止血带在现代高科技局部战争中应用的现状

战创伤条件下血管损伤非常多见,如不及时救治,可引起大出血,成为伤员早期死亡的重要原因。因此,及时而有效的止血对挽救伤员生命、稳定伤情、为后续治疗创造条件等有重要意义。由于止血带具有快速、有效止血及便于携带等优点,广泛用于战创伤肢体止血及为四肢手术提供无血手术视野。
