Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A primary aim of anaesthesia is to prevent awareness of surgery; ablation of the experience of surgery is the most secure way to prevent awareness with recall. Fortunately the incidence of awareness with recall (the patient can spontaneously remember the intraoperative event) is very rare (0.1-0.2%). However the investigators systematic review suggests that consciousness of intraoperative events may occur in approximately 37% of patients in experimental studies (as identified by the validated clinical procedure the isolated forearm test that does not require postoperative recall of the event). In this international cohort study, recruiting a minimum sample of 200 patients, the investigators will investigate the incidence of anaesthesia awareness (as identified by the isolated forearm test) following the induction of anaesthesia and before surgery.
