RESUMO
Gamma-hydroxybutyrate (GHB) is misused as an intoxicant, either alone or concurrently with other substances. Because GHB is illegal, the precursor chemicals 1,4-butanediol and gamma-butyrolactone are also misused for the same effect, either through pre-ingestion alteration or endogenous metabolism to GHB. We describe a case of a 50-year-old man with a history of polysubstance misuse who experienced an overdose of GHB from gamma-butyrolactone ingestion. The patient also co-ingested a common industrial solvent, N-methyl-2-pyrrolidone (NMP). This co-ingested substance raised theoretical concern of metabolism to a GHB congener, underscoring that the emergence of new psychoactive substance use patterns requires ongoing vigilance and toxicologic confirmation.

BACKGROUND: Using a reduced dose of 5 units of regular insulin has been proposed as a strategy to mitigate the risk of hypoglycemia when treating hyperkalemia. The comparative efficacy and safety of this strategy to conventional 10 units is not well established. OBJECTIVE: To compare the effectiveness of reduced and conventional dosed insulin for hyperkalemia treatment. METHODS: Electronic medication administration reports of conventional or reduced doses of insulin given for hyperkalemia treatment were reviewed from July 2013 to September 2015. The primary outcome was reduction in serum potassium. RESULTS: Ninety-two administrations of reduced dose insulin and 309 administrations of conventional dose insulin were included. No significant difference was found in potassium reduction between the groups (-0.096 mmol/L, P value = .2210). Post hoc subgroup analysis of patients with serum potassium > 6 mmol/L revealed a lower reduction in potassium in the reduced dose group compared to the conventional dose group (difference: -0.238 mmol/L, P value = .018). CONCLUSIONS: Conventional dose insulin may be more effective than reduced dose regular insulin at baseline serum potassium levels >6 mmol/L in the treatment of hyperkalemia. Frequent monitoring of serum potassium and glucose after administration of insulin is necessary to confirm adequate response and avoidance of hypoglycemia.

INTRODUCTION: Our objective was to assess postgraduate year one (PGY1) pharmacy resident perceived competence during medical emergencies before and after implementation of a longitudinal simulation training curriculum. METHODS: At the University of California San Francisco (UCSF) Medical Center, PGY1 pharmacy residents serve as primary code team responders for code blue, code sepsis, and code stroke, among other medical emergencies. In 2015, the UCSF Residency Training Program implemented a longitudinal simulation curriculum for PGY1 pharmacy residents. Throughout the residency year, residents participated in four simulation lab sessions that addressed various medical emergencies. To assess the impact that the simulation curriculum had on resident perceived competence during medical emergencies, a 19-question survey (13 clinical questions and six control questions) was distributed to the residents at the end of the residency year. Resident responses from the 2015 to 2016 and 2016 to 2017 surveys were compared to a control residency class from 2014 to 2015 who did not undergo the simulation curriculum. RESULTS: Simulation-trained PGY1 pharmacy residents reported significantly greater perceived competence in five of the twelve medical emergency scenarios (acute coronary syndromes, symptomatic bradycardia, supraventricular tachycardia, ventricular tachycardia, and cardiac arrest) as compared to non-simulation-trained controls. In addition, the PGY1 pharmacy residents felt that their performance as a clinical pharmacist would significantly improve as a result of the simulation curriculum. CONCLUSIONS: Incorporation of a longitudinal simulation curriculum into PGY1 pharmacy resident training can positively impact resident self-reported competence when performing essential pharmacist functions during medical emergencies.
