Predictors of Intensive Care Unit Stay After Pediatric Supraglottoplasty.

Importance: Supraglottoplasty is a common procedure performed without evidence-based postoperative management plans. Patients are routinely admitted to the intensive care unit (ICU) postoperatively, but this may not be necessary in all cases.

Objective: To determine (1) whether routine admission to the ICU after supraglottoplasty is warranted in all patients who undergo this procedure and (2) which factors predict requirement for ICU-level care.

Design, Setting, And Participants: Retrospective case series and analysis of immediate postoperative outcomes of all children aged 1 month to 18 years who underwent supraglottoplasty at 1 tertiary-care children's hospital from January 1, 2008, through January 31, 2014. Exclusion criteria included preoperative admission to the ICU, preoperative need for positive-pressure ventilation, history of major airway reconstruction, or any concomitant other major procedure.

Exposure: Supraglottoplasty.

Main Outcomes And Measures: Need for ICU-level care as defined by need for intubation, positive-pressure ventilation, multiple doses of racemic epinephrine, or oxygen via nasal cannula at greater than 4 L/min within the first 24 hours.

Results: Of 223 patients identified, 25 (11.2%) met our criteria for ICU-level care. Nine patients required intubation. Twenty of the 25 patients met ICU criteria within 4 hours of surgery. Univariate analysis was performed on 38 risk factors. Risk factors for ICU requirement that remained statistically significant on multivariable analysis (P < .05) included surgical duration longer than 30 minutes (odds ratio [OR], 4.48 [95% CI, 1.51-13.19]; P = .007), nonwhite race (OR, 4.42 [95% CI, 1.54-12.66]; P = .006), and a preoperative diagnosis of gastroesophageal reflux disease (OR, 0.10 [95% CI, 0.09-0.36]; P < .001).

Conclusions And Relevance: Our study suggests that most children undergoing supraglottoplasty do not require ICU-level care postoperatively. Those who require ICU-level care are likely to be identified within the first 4 hours after surgery. Consideration for routine ICU admission should be given to those with longer surgical duration and those of nonwhite race.
