Contraindication

Thiopental Sodium for Injection is contraindicated in patients with severe respiratory embarrassment, hypersensitivity to barbiturates, status asthmaticus, variegate or acute intermittent porphyria, and inflammatory conditions of the mouth, jaw, and neck and in the absence of suitable veins for intravenous administration. Thiopental Sodium for Injection is also relatively contraindicated in severe cardiovascular disease, hypotension or shock, and conditions in which the hypnotic effect may be prolonged or potentiated, i.e. excessive premedication, Addison’s disease, hepatic or renal dysfunction, myxedema, increased blood urea, severe anemia and myasthenia gravis.

Mode of Action

Thiopental sodium, a short-acting barbiturate anaesthetic, is a CNS depressant inducing hypnosis and anaesthesia but not analgesia. It has also been used in the control of refractory tonic-clonic status epilepticus and to reduce increased intracranial pressure in neurosurgical patients.

Precaution

Hypovolaemia; history of severe asthma, severe cardiac disease, severe anaemia, hyperkalaemia, toxaemia, myasthenia gravis, myxoedema; severe renal or hepatic disease; muscular dystrophies, adrenocortical insufficiency; increased intracranial pressure; elderly, pregnancy, lactation. Avoid extravasation or intra-arterial administration. IV inj of concentrated thiopental solution e.g. 5% may cause thrombophloebitis.

Side Effect

Coughing, hiccupping, sneezing, muscle twitching, laryngospasm, bronchospasm. IV: tissue necrosis (if extravasation occurs). Intra-arterial: Severe arterial spasm with burning pain, blanching of forearm and hands and gangrene of digits.

Potentially Fatal: Respiratory depression, arrhythmias, circulatory failure and anaphylactoid reactions.

Interaction

Possible increase in difficulty in producing anaesthesia in patients taking alcohol or CNS depressants. Additive action with other CNS depressants including sedatives, hypnotics, nitrous oxide or alcohol. Increased hypotension and excitatory effects with phenothiazine antipsychotics.
