A retrospective, observational, single-centre, cohort database analysis of the haemodynamic effects of low-dose spinal anaesthesia for hip fracture surgery

Careful administration of either spinal (intrathecal) or general anaesthesia probably has a greater impact on outcomes after hip fracture surgery than which method is used per se. Intraoperative hypotension is associated with poorer outcomes, but appears less prevalent using lower doses of spinal an...

Description
Summary:Careful administration of either spinal (intrathecal) or general anaesthesia probably has a greater impact on outcomes after hip fracture surgery than which method is used per se. Intraoperative hypotension is associated with poorer outcomes, but appears less prevalent using lower doses of spinal anaesthesia. In this observational single-centre study, intraoperative noninvasive blood pressure data were analysed from 280 patients undergoing unilateral hip fracture surgery after the administration of hyperbaric spinal bupivacaine 0.5%, 1.3 ml (0.65 mg). Mean cohort mean arterial pressure (MAP) remained within 10% of baseline (spinal injection) MAP for 97/98 (99.0%) subsequent aggregated 1-min recording intervals. The prevalences of lowest MAP
