Introduction: Pulmonary artery hypertension (PAH) in pregnancy is

Laparoscopic surgery has replaced many of the open surgeries because of its advantages. Both the groups of drugs have hemodynamic stability, analgesia, sedation and decrease the requirement of other anesthetic drugs. So we have chosen Butorphanol and Nalbuphine to study the analgesia and hemodynamic changes in both groups. In our study mean heart rate was lower in Butorphanol group compare to Nalbuphine group. Similarly fifty patients of ASA I&II scheduled for elective laparoscopic surgery, were randomized in to butorphanol group and nalbuphine group. It was observed that there was significant rise in systolic blood pressure & Diastolic Blood pressure after intubation in fentanyl group compare to Butorphanol. This study finds that suppression of sympathetic response to laryngoscopy and intubation was better with Butorphanol than Fentanyl. This study analysis indicates that both Butorphanol and Nalbuphine help in maintaining a steady haemodynamic state all  throughout  the procedure.
