Summary
Pain still remains a limiting factor in early discharge of patients undergoing laparoscopic
cholecystectomy. Almost all earlier studies done to compare the efficacy of local
anaesthetics used intraperitoneally as compared to intraincisionally used equal amounts of
drugs at the two locations, usually 10-20 ml. Using this large amount of drug in the small
space of intraincisional location as compared to similar amount of drug in large
intraperitoneal space created an inadvertent bias in favor of patients receiving the drug
intraincisionally so such patients naturally experienced less pain. The investigators decided
to standardize the drug used at these two locations as 1ml/cm and conduct a new study
comparing the effects of drugs in relieving pain when used at these two locations.
