Study Cohort
This retrospective cohort study was approved by the Institutional Review Board at Boston Children's Hospital. All neonates and infants who underwent cardiac surgery from January 2019 to December 2019 were identified. Among them, only patients who underwent surgery on CPB were included for analysis. Demographics, surgical type, surgical duration, CPB time, crossclamp time, blood product volumes, intraoperative respiratory data, postoperative mechanical respiratory support time, and postoperative
Characteristics of Infants and Neonates Undergoing Cardiac Surgery on Cardiopulmonary Bypass
Four hundred forty-one neonates and infants underwent cardiac surgery during the time period. Among them, 328 cases were performed on CPB. Their characteristics are shown in Table 1. Postoperative death was noted in 3.7% of patients, which was in line with the Kids’ Inpatient Database study.8 Figure 1 describes the type of surgery performed, and the types of surgeries performed in fewer than three patients were categorized as ‘other.’ The average duration of postoperative mechanical ventilatory
Discussion
Here the authors describe postoperative mechanical ventilatory support for neonates and infants who underwent CHD surgery on CPB. Surgical repair for VSD and CAVC, two overcirculation lesions, were the two most common procedures in this cohort. The authors found that 60% and 80% of neonates and infants after VSD and CAVC repair, respectively, demonstrated a P/F ratio <300, but more than 65% of VSD patients and 40% of CAVC patients did not require postoperative mechanical ventilatory support
