ObjectiveThe choice of oral or nasal endotracheal intubation in children undergoing cardiac surgery is affected by several factors. This study compared the outcomes of oral versus nasal intubation in neonates and infants who underwent open cardiac surgery.DesignA randomized, controlled, open-labeled study.SettingAt a university hospital.ParticipantsA total of 220 infants and neonates who underwent cardiac surgery.InterventionsPatients were allocated randomly to oral or nasal intubation.Measurements And Main ResultsThe primary outcome measure was postoperative fentanyl consumption (µg/kg/h) by intubated patients. Secondary outcome measures were the increase in heart rate (HR) from baseline during intubation, the time consumed for intubation, accidental intraoperative extubation, the occurrence of epistaxis, time to extubation, the onset of full oral feeding, intensive care unit (ICU) and hospital lengths of stay, and the incidence of postoperative complications (the need for reintubation, stridor, pneumonia, wound infection). The mean (SD) postoperative fentanyl consumption of intubated patients (the primary outcome) was significantly lower (p < 0.001) in the nasal intubation group (0.53 ± 0.48) µg/kg/h compared with the oral intubation group (0.82 ± 0.20) µg/kg/h. The median (IQR) time needed for the intubation (31.5, 27-35 v 16, 14.8-18 seconds) was significantly (p < 0.001) longer, and the mean (SD) increase in HR (beats/min) from baseline during intubation (18 ± 5 v 26 ± 7) was significantly (p < 0.001) lower in the nasal intubation group compared to the oral intubation group. The incidence of inadvertent intraoperative extubation was significantly (p = 0.029) higher in the oral (n = 6, 6.1%) than in the nasal (n = 0, 0%) intubation group. The median (IQR) time to extubation (14, 12.6-17.2 v 20.5, 16.4-25.4 hours) and the ICU length of stay (27, 26-28 v 30, 28-34 hours) were significantly (p < 0.05) shorter in the nasal group compared to the oral group. The median (IQR) time to onset of full oral feeding was significantly (p = 0.031) shorter in the nasal intubation group (3, 1-6 days) compared to the oral intubation group (4, 2-7 days). There were no significant differences between the oral and nasal groups in the duration of hospital stay and the indices for reintubation, postintubation stridor, pneumonia, and surgical wound infection.ConclusionsThe nasal route for intubation is associated with less postoperative fentanyl consumption, earlier extubation, lower incidence of accidental extubation, and earlier full oral feeding than oral intubation. The nasal route is not associated with an increased risk of postoperative pneumonia or surgical wound infection.Copyright © 2023 Elsevier Inc. All rights reserved.
