Divided into 2 groups: 1) General anesthesia;and 2) Lumbar sacral plexus block anesthesia. Variables measured in both groups were: demographics, conversion to general anesthesia, total opioid doses, surgical time, blood loss, postoperative pain, use and total dose of vasopressors drugs, transfusion and ICU transfer needs, postoperative ambulation time, and length of hospital stay. T student and chi-square tests were used upon the case. A significant difference was considered when a value of p < 0.05 was obtained. Descriptive statistics were performed in frequency, percentages, variance and standard deviation. <b>Results:</b> 3 patients (7.3%) anesthetized with combined lumbar sacral plexus block were converted to general anesthesia. When comparing peripheral nerve block and general anesthesia, less intraoperative (p = 0.000) and postoperative (p = 0.002) opioid consumption were noted, less postoperative pain in PACU (p = 0.002) and in the first 24 hours (p = 0.005), as well as earlier onset of ambulation (p = 0.008) and shorter hospital stay (p = 0.031). <b>Conclusions:</b> In our study, the lumbar and sacral plexus block anesthesia technique provided anesthetic conditions to perform hip joint arthroplasty and it was proved to be advantageous in comparison to general anesthesia.展开更多

Patients with pulmonary hypertension undergoing surgical procedures such as hemiarthroplasty present a high risk of fatal complications. Nonetheless, there are no widely accepted protocols explaining their perioperative care in great detail. Case presentation: We present a case with an 89-years-old patient, with comorbidities such as GOLD 4D chronic obstructive pulmonary disease (COPD) and, as a consequence of this, severe pulmonary hypertension with signs of right ventricular dysfunction, thus requiring of pulmonary vasodilator, that has suffered a subcapital hip fracture requiring urgent surgery. Surgery is carried out successfully, under regional lumbar-sacral plexus block and sedation assisted by non-invasive ventilation. Conclusion: Multidisciplinary specialized treatment, preoperative optimization, as well as the careful selection of both the surgical and anesthetic techniques to be used, are among the strategies that improve the perioperative outcome in patients with pulmonary hypertension with right ventricle systolic dysfunction. Regional lumbar-sacral plexus block plus sedation is a technique that maintains hemodynamic stability;however, these patients require advance measures and postoperative monitoring under intensive care.展开更多
目的:探讨超声引导下腰骶丛神经阻滞联合全麻对行髋关节置换术老年病人术后谵妄(POD)的影响。方法:选取髋关节置换术老年病人80例,随机分为腰骶丛神经阻滞联合全麻组(h组)和全麻组(q组),各40例。2组病人均采用喉罩通气,维持脑电双频指数...目的:探讨超声引导下腰骶丛神经阻滞联合全麻对行髋关节置换术老年病人术后谵妄(POD)的影响。方法:选取髋关节置换术老年病人80例,随机分为腰骶丛神经阻滞联合全麻组(h组)和全麻组(q组),各40例。2组病人均采用喉罩通气,维持脑电双频指数40~60,术后静脉自控镇痛(PCA)。比较2组病人术中麻醉药物用量、手术相关指标;采用视觉模拟量表(VAS)评估病人术后疼痛情况;于术前(D0)、术后第1(D1)、3(D3)、7(D7)天分别测定病人意识模糊评估量表(CAM)评分,并抽取静脉血检测白细胞介素(IL)-1β、IL-6、肿瘤坏死因子α(TNF-α)、C反应蛋白(CRP)和S100β蛋白水平。结果:与q组相比,h组病人术中麻醉药物用量、术后拔管时间、术后24 h PCA次数、术后各时间点VAS评分、首次下床时间及出院时间均明显减少(P<0.01);h组术后IL-1β、IL-6、TNF-α、CRP、S100β蛋白水平、CAM评分及POD发生率均明显低于q组(P<0.01)。结论:超声引导下腰骶丛神经阻滞联合全麻较单纯全麻,可减少行髋关节置换术的老年病人麻醉药用量,完善镇痛,降低炎性反应和POD发生率,有助于病人术后快速康复。展开更多
