Purpose: This study was designed to compare the new cuffed oropharyngeal airway (COPA) to the laryngeal mask airway (LMA) in elderly patients. Methods: In a randomized, controlled study, 80 patients, age ≥65, ASA I–III, undergoing urology procedures, were managed with either COPA or LMA. Propofol requirements for insertion of the devices, ease of insertion and removal, airway manipulations, mean arterial pressure, heart rate, PETCO2, SpO2, peak inspiratory pressure, selection of the appropriate size of the device and leaks, fibreoptic visualization of larynx and complications were studied. Results: There were more airway manipulations in the COPA group than in the LMA group (40% and 5% respectively) whereas PETCO2was higher in the LMA group (P < 0.05). In 60% of COPA patients the vocal cords could not be visualized but ventilation was adequate in all but two cases. Conclusion: In elderly patients COPA required more airway manipulations than the LMA. Laryngeal mask airway caused more sore throats, but was better for fibreoptic visualisation of the larynx. Both are excellent options when intubation is not indicated/desired. |
