Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Sugammadex as a single intravenous dose at the end of surgery with dose personalised by quantitative neuromuscular monitoring. Quantitative neuromuscular monitoring is recommended by the Australian and New Zealand College of Anaesthetists. It is applied at induction of anaesthesia and is removed after reversal of neuromuscular blockade at the end of surgery. Quantitative neuromuscular monitoring results, reversal drug name and dose will be recorded in the hospital medical record. Adherance to the intervention will be monitored via audit of the hospital medical record.

Summary
Brief summary
During general anaesthesia muscle relaxant drugs are administered to make airway management and surgery easier. Muscle relaxants are usually reversed with neostigmine at the end of the operation. A newer drug, sugammadex, reverses muscle relaxants more rapidly than neostigmine, but is not clear whether sugammadex results in fewer postoperative complications than neostigmine. We are conducting a large multi-centre randomised controlled trial to investigate whether sugammadex is associated with fewer postoperative lung complications than neostigmine.
