Advice in the perioperative period

Elective and emergency surgery 

Continue (including combination products). 

There are numerous inhaled preparations which contain antimuscarinics, either as single agents or in combination products with corticosteroids and/or beta agonists – all of these can be continued pre-operatively. Check active ingredients of currently available preparations in British National Formulary and see also Corticosteroids (Inhaled, Nebulised and Intranasal) drug records and Long-acting beta2 adrenoceptor agonists drug records and Short-acting beta2 adrenoceptor agonists drug records, if applicable.

Advise patients who are prescribed regular inhaled antimuscarinics but do not usually take them regularly to do so pre-operatively to optimise breathing prior to anaesthesia.

Confirm the inhaler brand, device, and strength with the patient.

Post-operative advice

Restart post-operatively as soon as next dose is due.

If patients are unable to resume their usual inhaled medication post-operatively consider nebulised ipratropium if clinically appropriate.

Interactions with common anaesthetic agents

Antimuscarinic action

Antimuscarinic action may be additive with agents that also have antimuscarinic effects such as atropine and glycopyrronium. Concomitant administration of inhaled antimuscarinics with other medication known to have antimuscarinic effects has not been studied and is therefore not recommended by the manufacturers; however, in practice monitor patient for adverse effects.

Interactions with other common medicines used in the perioperative period

Antimuscarinic action

Antiemetics

Antimuscarinic action may be additive with antiemetics that also have antimuscarinic effects such as cyclizine, haloperidol, levomepromazine or prochlorperazine.

Nefopam

Antimuscarinic action may be additive with nefopam which also has antimuscarinic effects.

Concomitant administration of inhaled antimuscarinics with other medication known to have antimuscarinic effects has not been studied and is therefore not recommended by the manufacturers; however, in practice monitor patient for adverse effects.
