Laparoscopic Cholecystectomy - Comparison of two different techniques of ultrasound guided blocks for postoperative pain relief
Keywords:Cholecystectomy, laparoscopy, postoperative pain management, erector spinae plane block.oblique subcostal transversus abdominis plane block
Background :Laparoscopic cholecystectomy (LC) can induce moderate postoperative pain due to small keyholes on the abdominal wall. The oblique subcostal transversus abdominis plane block(OSTAP)has been used for postoperative pain management after LC but found ineffective.Objective: Our aim is to compare the efficacy of erector spinae block with OSTAP block for postoperative pain management after LC.Material &Methods:Ninety patients, posted for LC were divided into three equal groups of 30 each. Erector spinae plane block was given in the ESP group. Oblique subcostal transversus abdominis plane block was given in the OSTAP group and IV analgesics were administered in control group for postoperative pain management. Postoperative rescue analgesic (paracetamol) consumption,time to 1st rescue analgesia request, numerical rating score (NRS), and any complications in 1st 24 hrs between the three groups were recorded and analyzed. Statistical Package for the Social Sciences version 21.0 was applied for statistical analysis. Descriptive statistics were expressed as mean ± standard deviation. Result:Postoperative rescue analgesia (paracetamol) consumption was 2.1± 0.76gm in ESP group , 2.90 ±0.18gm in OSTAP group and 4.16± 0.65gm in control group which was statistically significant. Time to 1st rescue analgesia request was 374.15±30.55 mins in ESP group, 294.61±43.18 mins in OSTAP group and 152± 37.44mins in control group which was statistically significant. Conclusion:Ultrasound guided ESP block is more effective in postoperative pain management after LC when compared to OSTAP group and control group.
