AbstractIntroduction: Local anaesthesia have been employed during the operation as an adjuvant to anaesthesia or to alleviate postoperative pain. Local anaesthetic is injected to block the nerves before cutting the skin at the beginning of the operation, or after closing the skin at the end. Subcutaneous infiltration of bupivacaine microcapsules prolongs analgesia in humans for up to 96 h, and pre surgical infiltration of levobupivacaine significantly decreases the intensity of postsurgical pain, especially for the first 12 h, thereby reducing analgesic consumption.
Methodology: The minimum samplesize required for the study per group is 23. We have considered 30 patients per group for better statistical representation. A total of 60 patients were included in the study.
Results: None of the patients suffered from bradycardia, hypoxaemia, respiratory depression, skin rash or incision site excessive redness nor was there any evidence of infection. The incidence of sedation and pruritis was similar in both groups with no statistically significant difference.
Conclusion: The incidence of nausea and vomiting was infact lower in group B as compared to group A. This could be explained by the lesser use of rescue analgesic agent in group B since Inj tramadol itself is associated with increased incidence of nausea and vomiting.
