ABSTRACT

AIM: To observe the anesthetic effect of nalbuphine used in ultrasound-guided transvaginal oocyte retrieval and its effect on embryo quality and pregnancy outcome. METHODS: Four-hundred patients who underwent ultrasound-guided transvaginal oocyte retrieval were randomly divided into two groups (n=200) nalbuphine group (N group) and control group (C group). The patients were in the bladder lithotomy position. Patients in N group were given nalbuphine 0.1 mg/kg intravenously 2 minutes before induction of anesthesia, patients in C group were given normal saline intravenously, and patients in both groups were induced with propofol 1.5 mg/kg.
