Aim: The aim of the present study to comparison of levobupivacaine alone versus levobupivacaine with ketamine in subcutaneous infiltration for postoperative analgesia in lower segment cesarean section. Material and Methods: A randomized double blind controlled study conducted in the Department of Anaesthesia, Jan Nayak Karpuri Thakur Medical college, Madhepura, Bihar, India, for 1 year. A total of 120 adult parturients of Physical status II or III as per the American society of anesthesiologists (ASA) without any medical or obstetrical problems, and scheduled for cesarean section under spinal anesthesia were included in this study. Parturients were randomized to one of the two groups (60 each) according to computergenerated random numbers kept in separate, sealed, and numbered envelopes. Group A parturients received subcutaneous surgical wound infiltration with a solution of 0.5% levobupivacaine at 2 mg/kg body weight (rounded to nearest multiple of 10) to a maximum of 150 mg (maximum safe dose) diluted with normal saline to a total of 32 ml. Group B parturients received subcutaneous surgical wound infiltration with a solution of 0.5% levobupivacaine 2 mg/kg body weight (rounded to nearest multiple of 10) to a maximum of 150 mg plus ketamine 1 mg/kg body weight diluted with normal saline to a total volume of 32 ml. The primary outcome, postoperative pain relief was measured using the VAS scale and the total analgesic consumption during the 24 hours postoperative period. Results: The zero hour (baseline) mean heart rates were comparable between groups A and B (P=0.891). The mean heart rate of group A was higher than that of group B which was statistically insignificant at majority of the time points except at 4 th and 6 th hour post operative. Conclusion: We concluded that the ketamine is an effective adjunct modality to levobupivacaine for local wound infiltration in terms of superior pain relief, lesser need for rescue opioid analgesia, and no major side effects.
