Comparison of the effects of endotracheal tube and laryngeal mask airway on immediate postoperative complications in elective operations

Abstract

Objectives: To compare the laryngeal and gastro-intestinal complications of using ETT and LMA after elective orthopedic operations. Materials & Methods: Eighty patients who were candidate for elective orthopedic 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 nausea, vomiting, coughing and sore throat were assessed in all patients during the first 24 hours. Results: Cases of nausea, vomiting and sore throat in LMA group were less than ETT group. However, this difference wasn't statistically significant. But cough incidence in ETT group was significantly further than the LMA group. Conclusion: There was no significant difference between the LMA and ETT regarding mentioned complications in the first 24 hours after the surgery. Of course more research is recommended in this area, considering the limitations and contrasting evidence. Copyright é 2010, Shiraz E Medical Journal. All rights reserved.
