A 64-year-old patient in the pre-operative holding area was awaiting surgery for carpal tunnel repair. A nurse started the patient's IV line and concluded the patient examination and interview. The anesthesia provider then saw the patient. He intended to administer midazolam, famotodine, metoclopramide and ondansetron, but inadvertently swapped syringes and administered succinylcholine instead. The error resulted in immediate respiratory paralysis to the patient, who was transported to the OR for intubation and general anesthesia.
