Class III/IV Obesity and Oocyte Retrieval Examined

Fertil Steril; 2019 Feb; Romanski, Farland, et al

Overall, oocyte retrieval can be safely performed as an outpatient procedure in women with class III and class IV obesity, according to a recent cohort study. Serious intraoperative and postoperative complications were uncommon across all body mass index (BMI) groups, though minor complications were more common with class III and class IV obesity. To assess the effect of class III (BMI 40–49.9 kg/m2) and class IV (BMI ≥ 50 kg/m2) obesity on oocyte retrieval complications and outcomes, researchers evaluated women who underwent an oocyte retrieval from January 1, 2012, to May 31, 2017. Women with BMI ≥40 kg/m2 (n=144) were age-matched to women with BMI <25, 25–29.9, 30–34.9, and 35–39.9 kg/m2 (n=1,016). They found:

  • Overall, 1,924 of 1,947 oocyte retrievals (98.8%) were performed under total intravenous anesthesia.
  • No patients with BMI ≥40 kg/m2 required intraoperative conversion to endotracheal intubation or hospital admission.
  • 2 patients (0.8%) with BMI ≥40 kg/m2 required a laryngeal mask airway intraoperatively owing to oxygen desaturation.
