In 1950, after a decade of 11 other unpublished New Zealand cases of tetanus with two recoveries, and another series treated by basal sedation with 50% surviving, DW Beaven (50) and his Christchurch team supplied a six-year-old boy with anaesthetic doses of tribromoethanol with 350 mg tubocurarine (d-TC) over [greater than or equal to] 12 days, to control his tetanus spasms and severe opisthotonus. The d-TC given was around 30 mg daily, with a 350 mg total.

However, because its use can result in poor muscle relaxation, muscle tremors, myotonic contractions, opisthotonus, and rough recovery, ketamine is rarely used alone (7-10); it is often paired with drugs such as alpha-adrenergic agonists, benzodiazepines, and propofol for chemical restraint and induction of anesthesia in birds.
