Abstract:
Educational Objective: At the conclusion of this presentation, the participants should be able to understand how demographic factors and disease severity predict anesthesia exposure and duration of treatment for subglottic stenosis.
Objectives: To determine how demographic factors and subglottic stenosis grade can be used to prognosticate anticipated anesthesia exposure and duration of treatment.
Study Design: Retrospective review.
Methods: Children treated for SGS with LTR, EBD, or both between November 2014 through August 2020 were included. Only patients completing their treatment course, defined as no airway procedure in a 12 month period, were included. All procedures and associated anesthesia time for the management and surveillance of SGS were included.
Results: Thirty-one patients met inclusion criteria. Patient gender did not influence total anesthesia time, number of procedures, or length of treatment course. Controlling for grade of stenosis, older children had fewer procedures (b= -0.34, p = 0.036). Patient age did not correlate with anesthesia exposure (b = -0.42, p = 0.100) nor duration of treatment course (b = -0.10, p = 0.101). Median total anesthesia time increased with grade of stenosis (grade I: 4.61 hours, grade II: 7.32, grade III: 11.03). The median total number of procedures was greater in higher grade stenosis compared to grade I stenosis (grade I: 5 procedures, grade II: 7, grade III: 7). Median duration of treatment was similar among patients with grade I and grade II stenosis but was increased in grade III stenosis (grade I: 0.81 years, grade II: 0.92, grade III: 1.78).
Conclusions: We found older patient age at initial treatment predicted fewer procedures, and higher grade stenosis predicted increased total anesthesia time, number of procedures, and duration of treatment.
