Emergency Endotracheal Intubations at a Pediatric Intensive Care Unit—Incidence and Hemodynamic Complications

Abstract

Emergency tracheal intubation (TI) in a critically ill child is a life-saving, high-risk procedure often associated with adverse events and complications. Efforts have been undertaken to increase the safety of TIs. Integrated checklists, simulation-based training, and video laryngoscope-assisted intubations have proven effective. The study's primary aim was to evaluate the frequency of emergency TIs at a pediatric intensive care unit (PICU) and to examine the incidence of peri-intubation hemodynamic complications. We conducted a single-center, retrospective analysis of unplanned (nonelective and emergency) intubations in a multidisciplinary PICU. Patients between 0 and 18 years admitted from January 2020 until December 2022 were included in the analysis. There was a total of 144 emergency TIs. In 92.6% of the cases, an underlying chronic disease existed. The most common indication for emergency TI was respiratory failure (61.0%). Adverse intubation-associated hemodynamic events were found in 18 (12.5%), cardiac arrest in 6 (4.2%), and emergency TI under ongoing cardiopulmonary resuscitation (CPR) in 12 (8.3%) cases. Twenty-two (15.3%) children died during the PICU stay after emergency TI due to the underlying condition. In the group of children showing adverse hemodynamic effects after TI, fewer children were on noninvasive respiratory support (50 vs. 75.2%, p = 0.007) and received catecholamine therapy more frequently before complicated emergency TI than those without complicated emergency TI (62.5 vs. 38.0%, p = 0.039). Children in the latter group had both a longer duration of mechanical ventilation (11 vs. 7 days, p = 0.045) and a longer PICU stay (18 vs. 12 days, p = 0.042) compared with the group of complicated emergency TIs. Most emergency TIs (59.0%) occurred off-hours, between 7 p.m. and 7 a.m., or on weekends. Emergency TIs occur unexpectedly, often outside regular operating hours, and are associated with a higher mortality and morbidity rate. Using noninvasive respiratory support could potentially reduce adverse intubation-associated hemodynamic events in emergency TI.
