The Effect of Intraperitoneal Nebulization: ropivacaine vs Lignocaine in Patients Undergoing Laparoscopic Cholecystectomy

INTERVENTION: Group L = Inj Lignocaine topical 4% 3mg/kg (maximum 4ml) Group R = Inj Ropivacaine 0.75% 3mg/kg (maximum 4ml) CONDITION: The Effect of Intraperitoneal Nebulization: Ropivacaine vs Lignocaine in Patients Undergoing Laparoscopic Cholecystectomy. PRIMARY OUTCOME: We conclude that intraperitoneal instillation of local an‐aesthetic is an easy, cheap, and non‐invasive method which provides better perioperative hemodynamic control along with good analgesia in the immediate postoperative period after laparoscopic surgery. This effect evaluated better with Lignocaine as compared to Ropivacaine. So Lignocaine can be used as a low cost alternative. SECONDARY OUTCOME: The chief limitation of the study is poor visualization of the surgical field for the first few minutes which may delay the surgical procedure INCLUSION CRITERIA: 100 patients of ASA I‐II, age 20‐60 yrs., wt. 40‐60 kg scheduled for routine elective lap surgeries under GA
