Background: Stress response to endotracheal intubation and surgery is associated with exaggerated hemodynamic response and an increase in catecholamine levels which is deleterious to both the mother and fetus. We aimed to compare the effects of intravenous nalbuphine and paracetamol on maternal hemodynamic status, neonatal APGAR score, and postoperative pain using the visual analog scale for elective cesarean section under general anesthesia. Study Design: This was a prospective, randomized, double-blinded clinical study. Materials and Methods: Sixty full-term pregnant patients, belonging to the American Society of Anaesthesiologist physical status Classes I and II, scheduled for elective cesarean section under general anesthesia were enrolled for the study. The patients were randomly allocated into two groups of 30 patients each to receive paracetamol (15− 1) in Group P and nalbuphine (0.2−1) in Group N before induction of general anesthesia. Maternal heart rate, blood pressure, and oxygen saturation were recorded before infusion of study drugs, after induction, after intubation, and during surgery across all periods. APGAR score of neonates was recorded by a pediatrician. Time to reach visual analogue score-1 was recorded. Results: Significant attenuation of maternal hemodynamic response was observed with nalbuphine compared to the paracetamol group (P < 0.05). The time to achieve visual analogue score-1 in the postoperative period was higher in the nalbuphine group. APGAR score at 1 min was significant between the groups and at 5 min, nonsignificant difference was observed (P > 0.05). Conclusion: Nalbuphine and paracetamol are effective in perioperative hemodynamic stability of mother and APGAR score of neonates. However, nalbuphine had better hemodynamic stability as compared to paracetamol with a comparable APGAR score at 5 min.
