Background/purpose: The ex-utero intrapartum treatment (EXIT) procedure is used to secure effective gas exchange prior to postnatal life. We describe the obstetrical course and maternal outcomes of a series of patients who underwent EXIT.
Methods: This is a review of all pregnancies in which fetuses were delivered by EXIT from January 2001 to April 2018. Outcome variables included estimated gestational age (EGA) at delivery, need for emergency EXIT, maternal estimated blood loss (EBL), need for maternal blood transfusion, and maternal postoperative length of hospital stay. Data were tested for normality and reported as median [range] and n (%).
Results: A total of 45 patients were delivered by EXIT procedure. Sixteen (35.6%) of the EXIT procedures were performed emergently. Median maternal EBL was 800 (500-2000) mL; 6 (13.3%) patients received blood transfusion. Median maternal postoperative length of hospital stay was four [3-7] days.
Conclusion: Our data highlight the complexity of the obstetrical management in the EXIT procedure as evidenced by an approximately 36% chance of emergency delivery. Despite having an experienced multidisciplinary team, 13.3% of our subjects underwent maternal blood transfusion. This information can be used in counseling EXIT candidates regarding the risks and benefits of this procedure.
