Accidental intramuscular vincristine: Lack of untoward effects and recommendations for management

Abstract

Vincristine was inadvertently injected into a thigh of three children. In each case the accident occurred as a result of the mixing of a syringe containing vincristine with a syringe of L-asparaginase which the patient was scheduled to receive on the same day. Within minutes, each patient was treated topically with cold compresses and the area was infiltrated with a solution of 8.4% sodium bicarbonate. Only one patient had discomfort of the thigh after the injection, none of the patients have had any sequelae, either acute or delayed. Measures to avoid mistaken injection of vincristine for asparaginase are readily achievable and have prevented recurrences of intramuscular vincristine administration at the institutions where they have been implemented. Nonetheless, other instances of intramuscular vincristine injection are anticipated and should be rapidly recognized and quickly managed with local applications of cold and sodium bicarbonate. Med.
