Background: The rationale of this study was to evaluate the efficacy of intrathecal hyperbaric ropivacaine for day case pelvic, perenial and lower limb surgeries.
Methods: Seventy ASA physical status I-II patients undergoing the above mentioned surgeries were enrolled for the study. Hyperbaric ropivacaine in a dose of 15 mg was injected intrathecally in each of the patients. The primary outcome variables of the study were- duration of sensory and motor block. Secondary outcome variables were- time for onset of sensory block to T10 dermatomal level and motor block to Bromage Score 3, maximum spread of sensory block, time to reach maximum sensory level, quality of intraoperative analgesia and muscle relaxation, time to mobilize, time to spontaneous voiding and side effects.
Results: The mean time for onset of sensory block to T10 dermatome level and motor block to Bromage Score 3 were 3.25 + 0.84 mins and 5.12 + 0.76 mins respectively. The median value of HSL was T5 (T4 - T6) and mean time to reach HSL was 9.08 + 1.05 mins. The total duration of sensory and motor block (mean) were 132.22 + 8.44 mins and 104 + 8.56 mins respectively. The time needed to mobilize the patients and spontaneous voiding (mean) were 206 + 9.26 and 230 + 10.33 mins respectively. Based on Modified Postanesthesia Discharge Scoring System (PADS) in addition to spontaneous micturition, 61 (87.14%) patients were discharged on the same day of operation.
Conclusion: Results have demonstrated that 15 mg of hyperbaric ropivacaine when injected intrathecally is sufficient to produce anesthesia for day case pelvic, perineal and lower limb surgeries.
