ABSTRACT
Background: Usually for lower abdomen and lower limb short surgical procedures, spinal anaesthesia is a reliable and safe anaesthesia technique.2-chloroprocaine (2-CP) is an amino-ester local anaesthetic with a very short half-life. Adjuvants are required with short acting local anaesthetic for spinal anaesthesia to prolong analgesia. Aims and Objectives: The present study was conducted to analyse the effect of 2-CP alone and with fentanyl combination in spinal anaesthesia for short surgical procedures in terms of onset of block, adequacy of anaesthesia, analgesia and recovery. Materials and Methods: The study was conducted in our hospital in 60 patients undergoing lower abdomen and lower limb short surgical procedures under spinal anaesthesia with either 2-CP or 2-CP and fentanyl (group I or group II) after randomisation into two groups. Spinal anaesthesia characteristics of sensory and motor block, duration of analgesia were noted and appropriate statistical analysis was performed. Results: The onset of sensory and motor block was faster in group II[5.00 ± 3.19 vs 7.156 ± 3.38 min. (p= 0.0138) and 8.03 ± 5.65 vs 11.03 ± 3.97 min. (p= 0.021)] than in group I, and duration of effective analgesia was prolonged in group II (147.63 ± 40.71 vs 130.40 ± 50.85 min with p value of 0.0002)as compared to group I. Eleven patients in group I required analgesic supplementation in the intraoperative period. Conclusion: The patients undergoing short surgical procedures of lower abdomen and lower limb under spinal anaesthesia with short acting local anaesthetic 2-CP with fentanyl as an additive provides rapid onset of sensory and motor block and prolonged duration of analgesia.
