Insights
Adhering to a 2-hour monitoring guideline after ambulatory surgery does not improve safety for infants under 6 months. Appropriate patient selection and physiological readiness are key for safe discharge, regardless of monitoring duration.
Area of Science:
- Pediatric Anesthesiology
- Surgical Outcomes
- Patient Safety
Background:
- Current American Academy of Pediatrics (AAP) guidelines mandate at least 2 hours of monitoring for infants under 6 months post-surgery.
- The necessity of this strict time-based monitoring for preventing adverse events in this age group undergoing ambulatory procedures requires further evaluation.
Purpose of the Study:
- To assess whether adherence to the AAP's 2-hour monitoring guideline reduces adverse events in infants younger than 6 months after ambulatory surgery.
- To determine if a shorter or more flexible monitoring period, based on physiological readiness, is safe for this patient population.
Main Methods:
- Retrospective analysis of electronic medical records for infants under 6 months who received anesthetic care between January 2015 and March 2020.
- Data collection included demographics, intraoperative adverse events, and 7-day postoperative emergency department (ED) or urgent care (UC) returns.
- Statistical analysis using chi-square or Fisher's exact tests to compare adverse event rates between groups.
Main Results:
- 1,177 infants with 1,261 anesthetic encounters were analyzed.
- Forty-four adverse events were identified: 20 (1.6%) pre-discharge (3 unplanned admissions) and 24 (1.9%) 7-day postoperative ED/UC returns.
- No significant difference in postoperative recovery time was observed between infants who experienced adverse events and those who did not (88 min vs. 77 min, P=0.078).
Conclusions:
- Strict adherence to a 2-hour time-based discharge criteria does not enhance safety for infants under 6 months post-ambulatory procedures.
- Appropriate patient selection and achieving physiological discharge readiness are crucial for safe outcomes.
- The findings suggest that current time-based guidelines may not be necessary if patients meet discharge criteria.
Abstract:
AAP guidelines recommend infants less than 6 months of age are monitored for at least 2 hours following surgery. This retrospective study evaluated if adherence to the 2-hour monitoring guideline decreased the risk of adverse events associated with ambulatory procedures in infants younger than 6 months.
Methods:
We queried the hospital's electronic medical record to identify patients younger than 6 months of age who received anesthetic care from January 2015 to March 2020. Demographic data, intraoperative adverse events, and returns to the emergency department (ED) or urgent care within 7 days were captured for each patient. We calculated the number and frequency for categorical data and median and interquartile range (IQR) for continuous data. Chi-square or Fisher's exact test were used to compare patients who experienced an adverse event to those that did not.
Results:
One thousand one hundred seventy-seven patients who had 1,261 unique anesthetic encounters were analyzed. Forty-four adverse events were identified, 20 (1.6%) before discharge, including 3 unplanned admissions, and 24 (1.9%) returns to the ED/UC within 7 days postoperatively. We did not observe differences in postoperative recovery time in patients who experienced an adverse event and those who did not (88 min vs. 77 min, respectively, P = 0.078). None of the ED/UC returns would have been avoided by a longer PACU stay.
Conclusions:
With the appropriate patient selection, once physiological discharge readiness is met, adherence to a strict 2-hour time-based discharge criteria does not increase safety for infants younger than 6 months of age after ambulatory procedures.
