Abstract
Background: Laryngeal mask airway (LMA) was introduced by Dr. Brain in 1980s and caused a revolution in airway management. Today, this device has a special position in anesthesiology procedures and among many of anesthesiologists. LMA provides a proper way for ventilating the patient while protecting his or her airway. Nowadays, LMA is used as a proper device for protecting the patient’s airway during many of the operations. However, American society of anesthesiologists, Australian and European council of resuscitation, and American heart Association approve the usage of LMA only in emergency situations and in cardio-pulmonary resuscitation. The reason for this issue seems to be the inadequate evidence on the efficacy and safety of LMA.
Objectives: This study was conduct to compare the pharyngolaryngeal complications of using ETT and LMA after elective operations in the 1st 24 hrs. Post operation.
Materials & Methods: sixty patients who were candidate for elective intermediate duration operation and were in class 1 and 2 of ASA, participated in this study and Patients randomized into two groups. Laryngeal Mask Airway (LMA) was used in one group and Endo Tracheal Tube (ETT) in the other one. Postoperative complications including pain at the pharyngolaryngeal area, sore throat, laryngeal spasm and hoarseness of voice were assessed in all patients during 1st 24 hrs.
Results: The results of the study indicated that in the first 24 hours after the surgery there was no significant difference between the patients of two groups regarding coughing and hoarseness of voice, but the difference regarding pain, sore throat and spasm was significant in the rate and the nature.
Conclusion: LMA is more comfortable to patient than EET post operatively regarding sore throat, spasm, and laryngeal spasm in elective cases, but there is no difference in coughing and hoarseness of voice.
