Inclusion criteria

Inclusion criteria: Adult patients presenting to RUH for day case and minor in-patient operations who meet the inclusion criteria for the trial and who are to be anaesthetised by any of the investigators. All patients who are having an anaesthetic where the CLMA would be expected to be the airway used are suitable to be recruited. We will study 130 adult patients (American Society of Anaesthesiologists physical status 1 - 3 age >16 years) undergoing non-emergency surgery in the supine or lithotomy position under general anaesthesia with spontaneous respiration during maintenance of anaesthesia.

Exclusion criteria

Exclusion criteria: 1. Patients will not be studied if they have any pathology of the neck 2. At risk of pulmonary aspiration of gastric contents 3. Unable to understand the study or give informed consent to take part 4. We will not study patients weighing less than 35 kg or greater than 120 kg
