Effect of pneumatic leg compression on post-induction hypotension in elderly patients undergoing robot-assisted laparoscopic prostatectomy: a double-blind randomised controlled trial

Post-induction hypotension is common and associated with postoperative complications. We hypothesised that pneumatic leg compression reduces post-induction hypotension in elderly patients undergoing robot-assisted laparoscopic prostatectomy. In this double-blind randomised study, patients were allocated randomly to the pneumatic leg compression group (n = 50) or control (n = 50). In the intervention group, pneumatic leg compression was initiated before induction of anaesthesia. In the control group, pneumatic leg compression was initiated 20 min after anaesthesia induction. The primary outcome was the incidence of post-induction hypotension in these groups. Post-induction hypotension was defined as systolic blood pressure < 90 mmHg during the first 20 min after induction. Haemodynamic variables and area under the curve of post-induction systolic blood pressure over time were assessed. Complications associated with pneumatic leg compression were recorded, including: peripheral neuropathy; compartment syndrome; extensive bullae beneath the leg sleeves; and pulmonary thromboembolism. The incidence of post-induction hypotension decreased in the pneumatic leg compression group compared with that in the control group; 5 (10%) vs. 29 (58%), respectively, p < 0.001. In the pneumatic leg compression group, the lowest systolic, diastolic and mean blood pressures 20 min after induction of anaesthesia were significantly greater than the control group. Pneumatic leg compression resulted in an increased area under the curve of systolic blood pressure in the first 20 min after induction, p = 0.001. There were no pneumatic leg compression-related complications. Pneumatic leg compression reduced post-induction hypotension in elderly patients undergoing robot-assisted laparoscopic prostatectomy, suggesting that it is an effective and safe intervention to prevent post-induction hypotension among elderly patients undergoing general anaesthesia.     

锁骨钩钢板内固定术后钢板钩与肩峰匹配性影像学研究

目的通过测量锁骨钩钢板内固定术后患者影像学资料，分析发生肩峰骨侵蚀的原因是否与钢板钩-肩峰匹配度相关。 方法回顾性分析2015年8月1日至2018年8月31日期间在上海市浦东医院骨科就诊的210例患者的影像学资料，210例患者均因肩锁关节脱位或锁骨远端骨折行锁骨钩钢板内固定治疗，其中男110例、女100例；年龄24~76岁，平均（44.60±8.75）岁；肩锁关节脱位70例，锁骨远端骨折140例。测量术后及终末随访患者肩锁关节正位X线片相关数据，按锁骨钩钢板术后是否发生肩峰骨侵蚀，将纳入患者分为3组：无骨侵蚀组（A组）、伴钢板钩移位骨侵蚀组（B组）、不伴移位的骨侵蚀组（C组），分别测量钢板钩-肩峰的匹配度（β），统计分析术后发生肩峰骨侵蚀与钢板钩-肩峰匹配度之间的关系。 结果纳入研究的210例患者术后随访24~64周，平均（32.0±6.5）周。A组患者115例，B组患者54例，C组患者41例。A组匹配度β（3.72±0.48）mm与B组β¹（6.91±0.84）mm比较差异有统计学意义（P<0.05）；A组匹配度β（3.72±0.48）mm与C组β²（5.88±0.65）mm比较差异有统计学意义（P<0.05）；B组匹配度β¹（6.91±0.84）mm与C组β²（5.88±0.65）mm比较差异有统计学意义（P<0.05）。 结论锁骨钩钢板内固定术后是否发生肩峰骨侵蚀与钢板钩-肩峰匹配度β存在明显相关性，钢板钩与肩峰之间的匹配度越好，β值越小，发生肩峰骨侵蚀的可能性更小。

以宫腔积液为首发症状的胃型宫颈腺癌1例报道并文献复习

宫腔积液指宫腔内液体积存(积水、积血或积脓),是绝经后女性常见体征之一,常于超声检查时发现。持续宫腔积液患者,需宫腔镜检查寻找病因。本文报道1例以宫腔积液为首发症状,经宫腔镜检查确诊为胃型宫颈腺癌的患者。通过病例回顾并文献复习,以期为更多绝经后宫腔积液及宫颈病变的诊断提供参考,避免漏诊及误诊。1病例资料患者67岁,女,主因"绝经18年,不规则阴道出血2月"于2020年5月就诊于首都医科大学附属北京妇产医院妇科微创中心。
