Perianesthetic neurological adverse events in children: A review of the Wake‐Up Safe Database

Abstract

Background Perianesthetic neurological adverse events are rare in children and have been studied in detail in the settings of cardiac surgery and regional anesthesia. Our study aims to characterize perianesthetic neurological adverse events in children in the setting of all types of surgery and diagnostic or interventional procedures, to evaluate anesthesia's role, and to identify factors amenable to prevention. Methods We conducted a retrospective study by reviewing all the anesthetic encounters reported in the Wake‐Up Safe database between January 2010 and December 2017. Results The rate of perianesthetic neurological adverse events was 0.49 per 10 000 pediatric anesthetic encounters. The odds of NAE were significantly higher in children who were older than 6 months; had American Society of Anesthesiologists physical status (ASA PS) of 3, 4, or 5; or had American Society of Anesthesiologists Emergency (ASA E) status. Seizures were the most common NAE. Overall, 23 (18.1%) children with neurological adverse events died, and 33 (26%) experienced permanent or severe permanent harm. The risk of death was higher in infants and in children with ASA PS of 3, 4, or 5; ASA E status; preexisting neurological abnormality; or preexisting neurological deficit and in events associated with cardiac arrest or trauma. Anesthesia contributed to 24 (18.9%) events; patient disease was the primary causative factor in 95 (74.8%) adverse events, and 37 (29.1%) events were preventable, including 2 deaths. Preventable factors broadly included inadequate preoptimization, complications during airway management and central venous catheter placement, and suboptimal patient positioning. Conclusion Perianesthetic neurological adverse events are rare in children and have a poor outcome. Our study has described pediatric perianesthetic neurological injury in detail and identified contributing factors that can be optimized during various phases of perianesthetic care. This information can be utilized during the informed consent process and to enhance the quality of care in children receiving anesthesia.

“…4,8 Recommendations were made regarding transfusion-associated hyperkalemic arrest following massive transfusions in the pediatric population. 9 Review of the database has led to more publications and communications of best practices regarding perioperative aspiration events, 10 peri-anesthetic neurologic adverse events, 11 and reports of awareness in the pediatric population. 12 WUS also evaluated adverse events occurring outside of the operating rooms such as the post-anesthesia care units, 13 diagnostic imaging areas, 14 and other off-site locations.…”
