Efficacy of bispectral index monitoring for prevention of anestheticawareness and complications during oocyte pick-up procedure

Abstract

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.

About “Efficacy of bispectral index monitoring for prevention of anesthetic awareness and complications during oocyte pick-up procedure”

“…I read the article "Efficacy of bispectral index monitoring for prevention of anesthetic awareness and complications during oocyte pick-up procedure" written by Urfalıoğlu et al (1) in the Turkish Journal of Medical Sciences with great interest. The authors have applied sedation with propofol infusion and sevoflurane during the oocyte pick-up (OPU) procedure and compared the efficacy of bispectral index (BIS) monitoring in preventing awareness during anesthesia.…”

“…Oocyte pick-up (OPU) procedure, which is conducted during in-vitro fertilization (IVF) treatment and described as the collecting of oocytes following ovary stimulation, is a short-duration procedure where daily anesthesia is often applied. An insufficient level of anesthesia and occurrence of pain, which are possible outcomes in relation with the dosages of anesthetic agents used during an anesthesia application, may cause unwanted results by giving rise to intraoperative patient mobility as well as anesthetic alertness (1).…”

“…The causes and risk factors of ADA and prevention methods have been defined in the literature. 4 The risk factors described in the literature are as follows: high American Society of Anesthesiologists (ASA) scores, cardiopulmonary resuscitation, undergoing surgery in a major operation group, and undergoing emergency surgery.…”
