An International Multi-Centre Cohort Study of the Incidence of Anaesthesia Awareness Following Laryngoscopy and Intubation: The CONSciousness, Connectedness and IntraOperative Unresponsiveness Study (ConsCIOUS)
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.

Inclusion Criteria:
- Adult patients clinically requiring intubation will be included in this cohort.
- Patients must be able to follow the isolated forearm technique commands when awake
and prior to their operation will be included in this cohort.
Exclusion Criteria:
- Contraindication to isolated forearm technique test such as unable to have tourniquet
on arm for the isolated forearm technique (e.g. lymphedema or operative site).
