Chronic Pain,Functional Status,and Life Satisfaction Are Associated With Patients Living With HIV Discussing Advance Care Planning With Their Family or Friends

Context

In the era of effective antiretroviral therapy, persons living with HIV/AIDS (PLWHA) are living longer, transforming HIV from a universally fatal disease to a serious chronic illness, warranting discussions between patients and their loved ones about advance care planning (ACP). Evidence is needed on factors associated with patients' likelihood to discuss ACP with loved ones.

琥珀酰胆碱与罗库溴铵用于麻醉诱导对甲状腺手术患者术中喉返神经监测的影响[论著]

目的　比较常规剂量琥珀酰胆碱与小剂量罗库溴铵用于麻醉诱导对甲状腺手术患者术中喉返神经监测的影响。方法　选取2019年4月至2019年7月本院120例同一外科医师团队甲状腺手术喉返神经监测患者，随机分为A组：麻醉诱导肌松药物为琥珀胆碱1.5 mg/kg；B组：麻醉诱导肌松药物为罗库溴铵0.3 mg/kg。麻醉医师待肌松监测显示到最大抑制后，通过气管插管条件评分评估两组患者气管插管条件。记录各组插管时间、等待时间；迷走神经和喉返神经电信号基础值；以及术中血压波动、术后咽痛、声音嘶哑、低氧血症、苏醒延迟等并发症。外科医师通过神经肌电监测仪进行喉返神经刺激评估两组患者喉返神经监测情况。结果　A组患者气管插管条件优于B组，A组插管时间、肌松监测时间小于B组，两组手术监测时间差异无统计学意义。A组首次神经监测信号值大于B组，A组首次监测例数多于B组，两组患者术中无体动，血压下降差异无统计学意义。麻醉术后并发症，A组咽痛少于B组，A组有少量患者发生肌痛，差异无统计学意义。结论　1.5 mg/kg琥珀酰胆碱用于甲状腺手术患者的麻醉诱导，可以提供较好的插管条件，不影响外科医师术中行喉返神经监测，同时减少患者术后咽痛的发生。     

制何首乌的炮制方法探索

目的:考察黑豆汁炖制时间对制何首乌外观性状及各类有效成分含量变化规律的影响。方法:采用HPLC同时测定不同炮制时间制何首乌样品中二苯乙烯苷、大黄素、大黄素甲醚、大黄素-8-O-β-D-葡萄糖苷、大黄素甲醚-8-O-葡萄糖苷的含量,选择Agilent ZORBAX Extend-C_(18)色谱柱(4. 6 mm×250 mm,5μm),甲醇(A)-水(B)为流动相梯度洗脱(0～30 min,5%～100%A; 30～40 min,100%A),流速1. 0 mL·min~(-1),柱温35℃,检测波长280 nm。结果:随炖制时间的增加,二苯乙烯苷含量逐渐降低,与8 h时相比,至64 h时含量降低76%;大黄素-8-O-β-D-葡萄糖苷和大黄素甲醚-8-O-葡萄糖苷2种蒽醌苷含量先上升后下降,至24 h时达最高值,炖制40 h时降至与8 h近似的水平,之后略有波动;大黄素、大黄素甲醚2种蒽醌苷元含量先上升后下降,炖制32 h时达最大值,之后缓慢降低并趋于稳定。结论:炖制时间对制何首乌中各类成分含量的影响显著,且变化趋势不尽相同,应规范制何首乌饮片的炮制时间;同时,仅以二苯乙烯苷及蒽醌类成分作为制何首乌的指标性成分依据不够充分,应考虑增加多糖类等质量控制指标。     

Techniques and complications of popliteal nerve blocks

BackgroundUse of popliteal nerve blocks (PNBs) as an alternative or adjunctive therapy to traditional methods of pain control (e.g., systemic or spinal anesthesia and opioids) is increasingly popular in foot and ankle surgery.MethodsWe reviewed online databases for literature on PNBs in foot and ankle surgery to analyze the various techniques and positioning used, the influence of drugs on their efficacy, and possible complications associated with their use. Thirty articles were identified with a predefined search criteria, followed by a review process for relevance.ResultsPatient demographics, procedure specifics, and block techniques, such as anesthetic used, can impact the duration and success of a PNB. Administration with ultrasound guidance proved superior to nerve stimulation, and preoperative administration was superior to postoperative administration.ConclusionsPNBs are an effective method to control postoperative pain with minimal complications, leading to decreased analgesic use, earlier discharge, and higher patient satisfaction.Level of evidenceLevel III, retrospective comparative study
