Postoperative period is very crucial from recovery point of view. For fast and smooth recovery, postoperative period should be free of complications especially pain. It became more important in case of ceaserean section as patient also has to look after her baby. Cautious use of analgesic drugs has to be made in postoperative ceaserean section patient as they can adversely affect health of the baby also. Intraperitoneal instillation of ropivacaine is effective analgesic and has lesser side effects than pharmacological drugs. Our hypothesis is that intraperitoneal instillation of ropivacaine reduces postoperative pain in patients undergoing ceaserean section. This randomized control study was conducted on 60 patients of ASA grade 1 and 2 after taking ethics committee approval. Group I (n=30) is control group with no local infiltration and Group II (n=30) Local infiltration of 15 ml at incision site and intraperitoneal instillation of 5ml Inj. Ropivacaine 0.2%. Diastolic, systolic and mean blood pressure, heart rate were measured throughout the procedure. Time of rescue analgesia and VAS score was recorded postoperatively. Intraperitoneal instillation of 0.2% ropivacaine provides postoperative analgesia. Mean duration of rescue analgesia in group I was 115.67±4.09 that was significant (p<0.05) in comparison to group II 170.33±3.69. intraperitoneal instillation of 0.2% ropivacaine reduces postoperative pain in patients of ceaserean section under spinal anaesthesia.
