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
