Impact of modified-release opioid use on clinical outcomes following total hip and knee arthroplasty: a propensity score-matched cohort study

Modified-release opioids are often prescribed for the management of moderate to severe acute pain following total hip and knee arthroplasty, despite recommendations against their use due to increasing concerns regarding harm. The primary objective of this multicentre study was to examine the impact of modified-release opioid use on the incidence of opioid-related adverse events compared with immediate-release opioid use, among adult inpatients following total hip or knee arthroplasty. Data for total hip and knee arthroplasty inpatients receiving an opioid analgesic for postoperative analgesia during hospitalisation were collected from electronic medical records of three tertiary metropolitan hospitals in Australia. The primary outcome was the incidence of opioid-related adverse events during hospital admission. Patients who received modified with or without immediate-release opioids were matched to those receiving immediate-release opioids only (1:1) using nearest neighbour propensity score matching with patient and clinical characteristics as covariates. This included total opioid dose received. In the matched cohorts, patients given modified-release opioids (n = 347) experienced a higher incidence of opioid-related adverse events overall, compared with those given immediate-release opioids only (20.5%, 71/347 vs. 12.7%, 44/347; difference in proportions 7.8% [95%CI 2.3–13.3%]). Modified-release opioid use was associated with an increased risk of harm when used for acute pain during hospitalisation after total hip or knee arthroplasty.     

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.

1401例超长住院日患者分布与影响因素分析

目的分析超长住院患者分布及影响因素,探讨减少超长住院日的措施。方法从江苏省某三甲医院病案管理系统中调取2020年1月1日-2020年12月31日134016例出院患者的住院病案首页资料,对住院时间≥30天的1401例超长住院患者的分布特征进行统计描述,采用Logistic回归模型分析超长住院日的影响因素。结果2020年全院平均住院日为7.13天,其中超长住院患者平均住院日为41.85天。超长住院患者以60岁以上年龄组最多(39.61%);出院科室主要分布在血液科(42.18%)、普通外科(11.85%)、骨科(7.49%)等;疾病类别主要为肿瘤(47.32%)、影响健康状态和与保健机构接触的因素(10.56%)、循环系统疾病(7.07%)等;多因素Logistic回归结果显示,男性(OR=1.188)、离院方式为非医嘱离院或其他(OR=2.046)和死亡病例(OR=3.362)是超长住院的危险因素。结论控制超长住院日对平均住院日影响显著,医院应加强重点人群、重点科室和重点病种管理提高诊疗管理水平,缩短平均住院日。     

集束化干预联合闭环管理对ICU多重耐药菌感染的防控效果

目的 探讨集束化干预策略联合闭环管理模式对ICU多重耐药菌感染的防控效果。方法选取2020年1~12月EICU住院患者275例作为对照组，实施常规管理；2021年1~10月EICU住院患者239例作为观察组，在常规管理基础上实施集束化干预策略联合闭环管理。结果实施后，观察组多重耐药菌感染发生率明显低于对照组；患者住院日显著低于对照组，4项护理措施执行率(隔离标识、手卫生、环境消毒、医务人员相关知识知晓)、病原学送检率显著高于对照组（均P<0.05）。结论集束化干预联合信息化闭环管理可有效降低EICU多重耐药菌感染发生率。     

腹腔镜与开腹手术治疗长径5~10 cm中危原发性胃间质瘤的安全性和有效性比较

目的　比较腹腔镜和开腹手术治疗长径5~10 cm的中危胃间质瘤的安全性和有效性，并评估患者术后使用伊马替尼辅助治疗是否有明显益处。方法　回顾性分析2010年1月—2020年7月在南京大学医学院附属鼓楼医院接受手术治疗的72例长径在5~10 cm的中危胃间质瘤患者资料。其中腹腔镜手术组28例，开腹手术组44例。比较两组患者基本资料、病理特征、围手术期结果、住院总费用。对比术后使用和不使用伊马替尼辅助治疗的生存率。结果　开腹组和腹腔镜组临床病理特征差异无统计学意义（P>0.05）。腹腔镜组术后并发症发生率为32.1%（9/28），开腹组为52.3%（23/44），两组比较差异无统计学意义（P=0.094）。与开腹组相比，腹腔镜组总住院时间明显缩短［（12.5±3.2） d比（15.0±3.5） d，P=0.004］；术后中位住院天数明显缩短（7.5 d 比 9.0 d，P=0.006）；首次排气时间明显缩短（P=0.003）。中位随访时间58个月（13~129个月），期间未出现与肿瘤相关的死亡病例。开腹组有2例死亡，分别因乳腺癌和心脏病；腹腔镜组有1例死亡，死亡原因与胃间质瘤无关。72例患者中，40例术后接受伊马替尼辅助治疗，开腹组22例（50.0%），腹腔镜组18例（64.3%），两组接受伊马替尼辅助治疗的患者例数占比差异无统计学意义（χ2=1.414，P=0.234）。术后使用伊马替尼辅助治疗组总体生存率与未使用伊马替尼辅助治疗组相比差异有统计学意义 （P=0.015）。结论　与开腹手术相比，腹腔镜治疗长径在5~10 cm的中危胃间质瘤是一种安全有效的方法。实现R0切除的长径在5~10 cm的中危胃间质瘤患者术后使用伊马替尼辅助治疗未增加生存率，且未使用伊马替尼者未出现与肿瘤相关的死亡、复发及转移。
