Methohexital Sodium

INDICATIONS AND USAGE Methohexital Sodium for Injection can be used in adults as follows: 1.For intravenous induction of anesthesia prior to the use of other general anesthetic agents. 2.For intravenous induction of anesthesia and as an adjunct to subpotent inhalational anesthetic agents (such as nitrous oxide in oxygen) for short surgical procedures; Methohexital Sodium for Injection may be given by infusion or intermittent injection. 3.For use along with other parenteral agents, usually narcotic analgesics, to supplement subpotent inhalational anesthetic agents (such as nitrous oxide in oxygen) for longer surgical procedures. 4.As intravenous anesthesia for short surgical, diagnostic, or therapeutic procedures associated with minimal painful stimuli (see WARNINGS).

ADVERSE REACTIONS Side effects associated with Methohexital Sodium for Injection are extensions of pharmacologic effects and include: Cardiovascular Circulatory depression, thrombophlebitis, hypotension, tachycardia, peripheral vascular collapse, and convulsions in association with cardiorespiratory arrest. Respiratory Respiratory depression (including apnea), cardiorespiratory arrest, laryngospasm, bronchospasm, hiccups, and dyspnea Neurologic Skeletal muscle hyperactivity (twitching), injury to nerves adjacent to injection site, and seizures Psychiatric Emergence delirium, restlessness, and anxiety may occur, especially in the presence of postoperative pain Gastrointestinal Nausea, emesis, abdominal pain, and liver function tests abnormal Allergic Erythema, pruritus, urticaria, and cases...

WARNING Methohexital Sodium for Injection should be used only in hospital or ambulatory care settings that provide for continuous monitoring of respiratory (e.g. pulse oximetry) and cardiac function. Immediate availability of resuscitative drugs and age- and size-appropriate equipment for bag/valve/mask ventilation and intubation and personnel trained in their use and skilled in airway management should be assured. WARNINGS As with all potent anesthetic agents and adjuncts, Methohexital Sodium for Injection should be used only in hospital or ambulatory care settings that provide for continuous monitoring of respiratory (e.g. pulse oximetry) and cardiac function. Immediate availability of resuscitative drugs and age- and size-appropriate equipment for bag/valve/mask ventilation and intubation and personnel trained in their use and skilled in airway management should be assured. For deeply sedated patients, a designated individual other than the practitioner performing the procedure should be present to continuously monitor the patient. Maintenance of a patent airway and adequacy of ventilation must be ensured during induction and maintenance of anesthesia with methohexital sodium solution. CONTRAINDICATIONS Methohexital Sodium for Injection is contraindicated in patients in whom general anesthesia is contraindicated, in those with latent or manifest porphyria, or in patients with a known hypersensitivity to barbiturates.
