Anesthetic management for oocyte retrieval: An exploratory analysis comparing outcome in in vitro fertilization cycles with and without pre-implantation genetic diagnosis

Purpose: To date, there has been no comparison of outcomes in women undergoing anesthesia for in vitro fertilization (IVF) oocyte retrieval for the purpose of pre-implantation genetic diagnosis (PGD) because of their or their partner′s genetic disease relative to the outcome in women requiring IVF because of fertility issues. Materials and Methods: A prospective observational study, wherein all demographic and anesthetic management data were collected from IVF and PGD units′ records for a 6-month period. Descriptive analyses and parametric tests were employed. Results: There were 307 cases IVF and 76 cases PGD: most (97.4% and 99.7%, respectively) received general anesthesia with propofol and fentanyl ± dipyrone (90.5% and 93.3%, respectively) with no adverse effects. The only statistically significant difference between IVF and PGD groups that was potentially clinically significant was post-procedure recovery time (23.0 ± 20.4 vs. 29.4 ± 35.8 min, respectively; P < 0.0001), but is explainable as greater caution by Anesthesiologists for higher-risk PGD cases having autosomal dominant diseases that may impact anesthesia management (myotonic dystrophy, neurofibromatosis, Marfan′s); two of these cases also recovered in the general post-anesthesia care unit, as a precaution for early diagnosis and treatment of potential post-procedural complication. Conclusions: Results of this first-ever survey of anesthesia for PGD compared with IVF cases imply that propofol-and-fentanyl-based anesthesia is safe and can be recommended, bearing in mind that with patients who have autosomal dominant diseases impacting anesthetic management it is prudent to be more cautious post-recovery
