: Laparoscopic [LC] surgeries or minimally invasive surgeries are associated with lesser parietal pain and haemorrhage, compared to the open surgeries. However visceral pain persists. The effect of volume and concentration on intra-peritoneal instillation of local anaesthetics for pain relief has not been studied . In this study we have compared the intraperitoneal instillation of local anaesthetic with transversus abdominis plane block (TAP). This study is aimed at assessing the superiority of effect of volume of local anaesthetic instilled intra-peritoneally versus TAP block on post-operative pain relief in laparoscopic cholecystectomy.
