A Comparison of Fast v/s Slow Spinal Injection Speed on Hypotension and Sensory Level Onset: A Randomised Study

Dr. Krishna Dave, Dr. Kinna Shah, Dr. Bipin Patel

Abstract: Spinal anaesthesia is commonly employed for procedures involving lower abdominal and limb regions. While this technique induces a profound nerve block, it is associated with significant hypotension. The purpose of the study was to evaluate the influence of injection speed in spinal anaesthesia. We studied 120 patients undergoing elective lower abdomen and lower limb surgeries. They were randomly allocated into two groups, Group F received a 0.5% heavy bupivacaine spinal anaesthetic agent at 15 seconds and Group S at 60 seconds. Time to reach T10 sensory level along with changes in heart rate (HR), systolic and diastolic blood pressure (SBP, DBP), measured at baseline, 1, 3, 5 and 10 minutes after injection was recorded. In group F, the time to attain T10 sensory block was 6 ?2 minutes, whereas in group S it was 8?2 minutes (p<0.01).50% of cases in Group F produced hypotension and 30% in Group S with p=0.01. The fast spinal injection group resulted in early onset of sensory level at T10 (p<0.01) and more incidence of hypotension (p=0.01) with the fast injection speed. We suggest using fast injection speed with adequate IV fluid preloading.
