In a 59-year-old woman with a perforating eyeball injury to the right eye, the emergency physician induced a preclinical general anesthesia with propofol, fentanyl and the depolarizing muscle relaxant succinylcholine. Anesthesia was maintained using propofol and remifentanil infusion throughout the preoperative period and the subsequent surgical procedure. Postoperatively, isolated rhabdomyolysis with an increase in serum creatine kinase to >20,000 U/l was observed. ⋯ Warning symptoms, such as unspecific tachycardia or masseter spasm following succinylcholine injection, should alert emergency physicians to include MH susceptibility in the differential diagnostics. With an estimated genetic MH prevalence of 1:2000-3000, individuals with known or so far unrecognized MH disposition are likely to be among patients treated in the preclinical setting. If a person develops MH symptoms after exposure to triggering agents, immediate hospital admission is essential in order to initiate guideline-conform treatment without further delay because preclinically the life-saving causal measures are not possible due to the lack of supply of dantrolene.

We report the case of a young man who took a large amount of caffeine powder dissolved in water in a suicide attempt. He was found comatose. ⋯ In hospital he suffered from rhabdomyolysis with renal failure and sepsis rapidly developed. After renal replacement treatment with hemodialysis, long-term artificial ventilation with tracheotomy and a 3‑week stay in the intensive care unit, the patient could be discharged to a rehabilitation center.

Rapid sequence induction (RSI) is a specific technique for anesthesia induction, which is performed in patients with an increased risk for pulmonary aspiration (e.g. intestinal obstruction, severe injuries and cesarean section). The incidence of acute respiratory distress syndrome (ARDS) is very low but 10-30% of anesthesia-related deaths are caused by the consequences of ARDS. The classical RSI with its main components (i.e. head-up position, avoidance of positive pressure ventilation and administration of succinylcholine) was published nearly 50 years ago and has remained almost unchanged. ⋯ Succinylcholine 1.0 mg/kg or rocuronium 1.0-1.2 mg/kg should be administered to achieve excellent intubation conditions. The use of cricoid pressure was a cornerstone of RSI after its introduction in 1961; however, after controversial discussions in recent years, cricoid pressure has lost its importance. Before surgery gastric emptying with a nasogastric tube is mandatory in patients with ileus and passage or defecation disorders.
