ADEQUACY OF VENTILATION DURING GENERAL ANAESTHESIA USING A CUFFED OROPHARYNGEAL AIRWAY OR LARYNGEAL MASK AIRWAY

Abstract

SUMMARY AND CONCLUSION Maintainance of a clear airway during general anesthesia using a face-mask normally requires support of the lower jaw. Constant attention to the position of the patient's head and of the face mask which makes this technique unpopular for all but the shortest surgical procedures. Pressure injury, to nerves and eyes may also occur.Tracheal intubation rarely causes injury although damage to teeth and soft tissues may occur and postoperative sore throat is common. Both laryngeal Mask Airway (LMA) and Cuffed Oropharyngeal Airway (COPA) are non invasive devices that avoid the hazardes of laryngoscopy and intubation. They are less stimulating and the technique of insertion is easier to learn. So effective evalution of adequacy of ventilation of these devices is our aim in the study.

This study was carried out on 100 adult patients ASAl. II undergoing elective surgery under general anesthesia in which they are breathing spontaneously. patients included in the study were randomly allocated into two equal groups each group contain 50 patients.
