Effectiveness of intraperitoneal instillation of normal saline in reducing shoulder tip pain following laparoscopic cholecystectomy.

Patient who are found fit in preanesthetic checkup will be posted for laparoscopic cholecystectomy. Laparoscopiccholecystectomy will be performed after creating pneumoperitoneum with carbon dioxide insufflation under standard pressure of 12 mmHg. After removing gall bladder as per standard surgical technique patient in the intervention group will receive intraperitoneal instillation of normal saline at body temperature in the right hemidiaphragmaticarea until the whole liver is submerged. After irrigating, whole of intraperitoneal fluid in group A will be evacuated by negative suction drainage whereas in other group no such instillation of normal saline will be done. After performing the procedure all port site will be closed. Patient where drain has been put will be excluded from the study. After performing procedure right shoulder tip pain will be assessed at 6, 12, 24 and 48h using visual analogue scale (VAS). In which pain intensity score of 0 represents no pain, 1-3 mild pain , 4-6 moderate pain, 7-10 indicates severe pain23. The pain scores using VAS will be entered on patient’s proforma. Both the patient and observer willbe blinded to the type of intervention the

patient has received. Data will be recorded concerning duration of surgery, bile spillage during operation, frequencyand intensity of shoulder-tip pain.
