Abstract

OBJECTIVE: The objective of this study was to determine if supportive care without endotracheal intubation in the emergency department (ED) was safe in the absence of complications in gamma-hydroxybutyrate (GHB)/gammabutyrolactone (GBL) intoxicated patients with a decreased Glasgow Coma Scale (GCS) score.

METHODS: This was a retrospective chart review of patients presenting to a Dutch tertiary urban ED with a reduced level of consciousness related to alleged GHB/GBL intoxication between April 2011-December 2014. Primary endpoint was major adverse events, defined by: upper airway obstruction not resolved with mayo tube or nasopharyngeal airway, hypoxia not resolved with 15 l of oxygen delivered via non-rebreathing mask, bradypnea not resolved after stimulation, intubation, bradycardia not resolved after intravenous atropine bolus, hypotension for which inotropes were started.

RESULTS: Data of 209 patients were retrieved. Major adverse events were reported in five patients (2.4%; 95% CI: 0.8-5.5). Intubation with subsequent ICU admission was required for 1.4% of patients (95% CI: 0.3-4.1). The most frequently seen minor adverse events (N = 209) were: airway obstruction (22%), hypothermia (14.8%), hypoxia (12.9%), bradycardia (8.1%), hypotension (6.7%), bradypnea (5.7%), vomiting (5.3%). There were no deaths. None of the patients had signs of aspiration pneumonia or returned to our ED due to complications.

CONCLUSION: Our study suggests that conservative airway management for patients with a decreased GCS due to suspected GHB intoxication may be safe. Major adverse events were present in 2.4% of patients, only 1.4% of patients required intubation. All minor adverse events were managed effectively with conservative treatment.
