Pengaruh Duduk 5 Menit Dibanding dengan Langsung Dibaringkan pada Pasien yang Dilakukan Anestesi Spinal dengan Bupivakain Hiperbarik 0,5% 10 mg terhadap Perubahan Tekanan Arteri Rata-rata dan Blokade Sensorik

Abstract

Spinal anesthesia frequently results in hypotension due to high sympathetic blockade. The aim of this study was to examine effect of sitting for 5 minutes compared to immediately lying down after 10 mg of 0.5% hiperbaric bupivacaine administration with regards to the mean arterial pressure and level sensory blockade in patients who underwentd spinal anesthesia. This was a single blind randomized controlled trial in 36 patients with American Society of Anesthesiologists (ASA) I–II undergoing lower abdominal and lower extremities surgery under spinal anesthesia in Dr. Hasan Sadikin General Hospital Bandung during the period of March to May 2015. Data were statistically analyzed using Mann Whitney test for mean arterial pressure and Kolmogorov Smirnov test for level sensory blockade. The results showed a decrease of mean arterial pressure in group 1 (sitting 5 minutes) which was lower than group 2 (immediately lying down) with significant difference (p<0.05). Level of sensory blockade in group 1 at T 10 (14 from 18) was higher than in group 2 at T6 (8 from 18, p=0.001). It is concluded in this study that sitting for 5 minutes after spinal anesthesia using 10 mg 0.5%. bupivacaine hiperbaric decreases the intraoperative sensory of blockade height and mean arterial pressure.
