ObjectiveTo assess the performance of the COPA device during general anaesthesia.Study DesignProspective, clinical, open study.PatientsEighty patients scheduled for short elective surgical procedures under general anaesthesia not requiring tracheal intubation.MethodAfter premedication (midazolam, atropine), anaesthesia was induced with propofol (154 +/- 40 mg = 2.47 +/- 0.8 mg.kg-1) and alfentanil (1.14 +/- 0.43 mg). The COPA device was inserted in a fashion similar to a Guedel airway device. The device was evaluated on the following criteria: correct choice of COPA size, ease of insertion, ability to obtain or maintain patent airway. Adverse reactions were noted, such as coughing, nausea, regurgitation, inhalation, and sore throat. The overall rating of the COPA as a "hand free device" was evaluated on the basis of excellent, good, fair, and poor.ResultsInsertion of the device was easy and in 70 cases successful on the first attempt. Jaw thrust on head tilt was necessary in half the cases. No patient necessitated intubation because of hypoxaemia or airway obstruction. Adverse reactions occurred in few cases and consisted of sore throat (always moderate) in 10% of the cases. COPA was evaluated as excellent or good in 80% of the cases.ConclusionCOPA is a convenient device for airway management in fasting patients undergoing general anaesthesia for elective surgery in the supine position, in whom tracheal intubation is not indicated.
