Perbandingan Efektivitas Anestesi Spinal Menggunakan Bupivakain Isobarik dengan Bupivakain Hiperbarik pada Pasien yang Menjalani Operasi Abdomen Bagian Bawah

Abstract

Distribution of local anesthetics in spinal anesthesia is most determined by baricity and position. The study was conducted to explore the comparison of effect between spinal anesthesia technique using 0.5% isobaric bupivacaine with 0.5% hyperbaric bupivacaine on duration and level of sensory blocking action in lower abdominal surgery. This experimental study was conducted using randomized control trial (RCT) in 40 patients with physical ASA I–II status, aged 17–60 years, who underwent lower abdominal surgery in central operating theatre Dr. Hasan Sadikin Hospital-Bandung within January to April 2011. The patients were divided into two groups, the hyperbaric group and the isobaric group. The recording included sensory blocking level, sensory blocking duration, and statistical analysis using Student t-test and chi-square test. . Sensory blocking levels in isobaric group were lower than those in hyperbaric group. The conlusion of the study indicates that isobaric bupivacaine has lesser distribution and longer duration of action.
