Neuroleptic malignant syndrome (NMS) is described in the medical literature but rarely seen among acutely ill trauma patients. A 44-year-old man with burns to the hands and back after a chemical explosion was transported to an outside facility where he received treatment for presumed acute coronary syndrome after developing ventricular tachycardia and elevated serum troponins after the exposure. His cardiac catheterization was unremarkable, but an echocardiogram revealed severe cardiomyopathy, and he was also in multisystem organ failure. He was transferred to our facility after hospital day 2 for treatment of his multisystem organ failure and 2% total body surface area burns. His laboratory results were remarkable for a creatine kinase of >100 000 units/L, and he required 14 g of intravenous calcium. Upon further investigation, the patient reported taking ziprasidone for his bipolar disorder, and he had a core temperature of 103.5 °F on his initial presentation to the outside facility. As he convalesced, the unifying diagnosis was NMS. NMS is a side effect of antipsychotic therapy and is manifested by hyperpyrexia, rigidity, autonomic instability, and altered consciousness. An elevated creatine kinase >100 000 units/L is almost pathognomonic for NMS. Patients can also present with leukocytosis, organ failure, and electrolyte disturbances including hypocalcemia. We hypothesized that dehydration, the warm environmental conditions at our patient’s job, and immense stress resulting in a catecholamine surge following his trauma were inciting triggers to this event. This case highlights the importance of considering alternate diagnoses in patients whose clinical presentation does not fit the most “obvious cause.”
Current guidelines on the management of pain, agitation, and delirium in the intensive care unit (ICU) recommend a non-benzodiazepine (BDZ)–based approach to sedation. Management of agitation can be challenging in multitrauma patients but is imperative to facilitate patient recovery. Given the current guideline recommendations, a protocol to eliminate BDZ administration and maintain light levels of sedation was adopted in our ICU. The purpose of this analysis was to demonstrate that it is feasible to safely eliminate BDZ administration in a trauma ICU. This was a single-center, retrospective, observational analysis at a Level I trauma center. Adult patients (>18 years old) admitted to the Trauma Critical Care service from March 2015 to August 2015 were included. The primary outcome recorded was the use and duration of nonprocedural BDZs which was defined as BDZ not given within one hour of a procedure or test. A total of 64 patients met the inclusion criteria. The average Injury Severity Score was 18.7. A total of 14 patients (21.9%) received BDZ for a nonprocedure-related indication. Of those patients, all (100%) received less than three as-needed doses of BDZs during their ICU stay. In mechanically ventilated patients, continuous sedation or analgesia was not continued for more than 1.3 days. Only five patients (7.8%) received continuous BDZ. Limiting sedation is feasible in critically ill polytrauma patients. Protocols to standardize sedation strategies should be implemented in the ICU to avoid unnecessary sedation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
