Pediatric Procedural Sedation Using the Combination of Ketamine and Propofol Outside of the Emergency Department: A Report From the Pediatric Sedation Research Consortium

Abstract

Objectives: 

Outcomes associated with a sedative regimen comprised ketamine + propofol for pediatric procedural sedation outside of both the pediatric emergency department and operating room are underreported. We used the Pediatric Sedation Research Consortium database to describe a multicenter experience with ketamine + propofol by pediatric sedation providers.

Design: 

Prospective observational study of children receiving IV ketamine + propofol for procedural sedation outside of the operating room and emergency department using data abstracted from the Pediatric Sedation Research Consortium during 2007–2015.

Setting: 

Procedural sedation services from academic, community, free-standing children’s hospitals, and pediatric wards within general hospitals.

Patients: 

Children from birth to less than or equal to 21 years old.

Interventions: 

None.

Measurements and Main Results: 

A total of 7,313 pediatric procedural sedations were performed using IV ketamine + propofol as the primary sedative regimen. Median age was 84 months (range, < 1 mo to ≤ 21 yr; interquartile range, 36–144); 80.6% were American Society of Anesthesiologists-Physical Status less than III. The majority of sedation was performed in dedicated sedation or radiology units (76.1%). Procedures were successfully completed in 99.8% of patients. Anticholinergics (glycopyrrolate and atropine) or benzodiazepines (midazolam and lorazepam) were used in 14.2% and 41.3%, respectively. The overall adverse event and serious adverse event rates were 9.79% (95% CI, 9.12–10.49%) and 3.47% (95% CI, 3.07–3.92%), respectively. No deaths occurred. Risk factors associated with an increase in odds of adverse event included ASA status greater than or equal to III, dental suite, cardiac catheterization laboratory or radiology/sedation suite location, a primary diagnosis of having a gastrointestinal illness, and the coadministration of an anticholinergic.

Conclusions: 

Using Pediatric Sedation Research Consortium data, we describe the diverse use of IV ketamine + propofol for procedural sedation in the largest reported cohort of children to date. Data from this study may be used to design sufficiently powered prospective randomized, double-blind studies comparing outcomes of sedation between commonly administered sedative and analgesic medication regimens.
