Effects of posterior lumbar plexus block on anesthesia and sedation in postmenopausal patients with osteoporotic subtrochanteric comminuted fractures

Abstract

ABSTRACT To study the effect of posterior lumbar plexus nerve block on anaesthesia and sedation in postmenopausal patients with osteoporotic subtrochanteric femoral comminuted fractures. The research subjects selected 48 patients with postmenopausal osteoporotic subtrochanteric comminuted fractures who were hospitalized between January 2020 and January 2022, and were allocated to clusters according to the random number TBL approach. The controlling cluster (24 situations) underwent dura mater Under external anesthesia, the test cluster (24 situations) underwent posterior lumbar plexus block, and the block effect, anesthesia effect, sedation effect, hemodynamics, vital signs and reactions of adverse nature were contrasted involving the two clusters. In comparison to the control group, the test group had a longer duration of anesthesia and motor block, higher oxygenation indices but lower ITBVI, GEDVI, and ScrO2 values, lower MAP levels, and lower BIS contraction values at 5, 15, and 30 minutes following anesthesia (P < 0.05). The test group had shorter induction time and block onset time compared to the control group (P < 0.05), and a lower incidence of adverse reactions (16.67% vs. 29.17% in the control group), but the variation was not noTBL (P < 0.05). Posterior lumbar plexus nerve block in postmenopausal patients with osteoporotic subtrochanteric femoral comminuted fractures has a better sedative effect, shortens the induction time of anaesthesia and the onset of block, promotes sTBL haemodynamic indexes and has fewer adverse effects to ensure safety.
