Background/aim: This study was planned by considering that the use of bispectral index (BIS) monitoring ensures sufficient depth of
anesthesia and avoids
anesthetic awareness and patient movement in the oocyte pick-up (OPU) procedure.Materials and methods: Ninety-eight patients undergoing OPU were randomly divided into 2 groups as the control group (n = 48) and BIS group (n = 50). After
propofol and
remifentanil induction, the control group was given additional
propofol according to reaction response, while the BIS group was given
propofol at BIS values of 60 and above with the aim that BIS values be 40?60. Total procedure time, recovery time, patient movement, additional
propofol consumption, total number of oocytes, and
awareness during anesthesia were recorded. Results: Demographic data were similar in the two groups (P > 0.05 for all). The recovery time in the BIS group was significantly shorter compared to the control group (P < 0.001) while additional
propofol consumption was found to be significantly lower (P < 0.001). Baseline BIS values fell compared to all other times after induction significantly (P < 0.001). No patient had
anesthesia awareness.Conclusion: During the OPU procedure BIS monitoring is considered to prevent
anesthesia awareness, intraoperative movement, and complications caused by insufficient
anesthetic use as it ensures optimal doses of
anesthetic agents used and early recovery.
