Reducing intraoperative time with laryngeal mask airway and stretcher in pediatric adenotonsillectomy

Abstract Objectives Adenotonsillectomy (T&A) is one of the most common surgical procedures performed in the United States. Several studies have defined the safety of laryngeal mask airway (LMA) during this surgery, and conflicting evidence exists describing the role it plays in reducing intraoperative times. Our objective is to describe the role LMA and operating on a stretcher have on reducing intraoperative time during pediatric T&A. Methods This is a retrospective review between October 2017 and January 2020. We included patients between the ages of 4–18 years old undergoing T&A. We excluded medically complex patients with chromosomal, craniofacial, and metabolic abnormalities, patients with cerebral palsy, and those who were tracheostomy dependent. Patient demographics included surgical indication, age, sex, obesity, use of preoperative midazolam, type of airway used, use of traditional operating room (OR) bed versus transport stretcher, surgeon type, and intraoperative times. Data was analyzed with univariate t-test and multivariate linear regression. Results One hundred seventy-nine patients were included with an average age of 7.2 years. LMA and stretcher were used on 46.4% and 40.2% of patients, respectively. On multivariate linear regression LMA reduced emergence time by 4.4 min (p ≤ 0.001, 95% CI −6.7 to −2.1) and transport stretcher reduced induction time by 2.5 min (p = 0.04, 95% CI −4.9 to −0.1). Use of LMA and stretcher did not have a statistically significant difference on actual procedure time. Conclusion Our study further supports the role LMA has in reducing intraoperative times in addition to describing a novel method of reducing intraoperative time by operating on a transport stretcher for healthy children undergoing T&A. Level of evidence: 3.
