Extubation strategies after esophageal atresia repair

Abstract

Background/PurposeEarly extubation following repair of esophageal atresia (EA) is desirable unless the anastomosis is under tension, in which case paralysis and post-operative ventilation may reduce the risk of anastomotic leakage. However, complications from emergency reintubations do occur with either strategy. We aim to examine the risk/benefit balance of early and delayed extubation following EA repair. MethodsA seven-year retrospective review of all babies that underwent EA repair was performed. Babies extubated within 24 h of surgery were classified as early extubation (EE). Babies intubated beyond the first 24 h were classified as delayed extubation (DE). The EE group was subdivided into babies extubated in operating room (EIOR), and babies who returned to the neonatal intensive care unit (NICU) intubated but extubated within 24 h (EW24). ResultsForty-six babies were analyzed, and overall 15 (32.6%) required 24 reintubation episodes. Eight (28.6%) babies in the EE group required reintubation. The EIOR group (n = 12) had significantly increased risk of requiring reintubation (OR:7, 95%CI:1.08 to 45.16:p = 0.04) compared to the EW24 group (n = 16). Seven (38.9%) babies in the DE group required reintubation. The complication rate from reintubation after EA repair was 17%. ConclusionsExtubation on the NICU within 24 h of surgery carried the lowest risk of reintubation. For babies with a tight anastomosis, elective postoperative ventilation appeared to confer a protective benefit without incurring a high risk of complications from reintubation.
