Comparison of the Complications of Endotracheal Intubation with Laryngeal Mask Airway in Patients Under General Anesthesia

Abstract

Introduction: The two most popular methods for stabilizing the airway during general anesthesia are inserting the LMA and endotracheal intubation. The most critical stage in giving general anesthesia to patients who need artificial airway support because they are unable to keep their airways open enough on their own while sedated., the supports for establishing proper airway control, providing anesthetic, and avoiding aspiration have been laryngoscopy and endotracheal intubation. Inappropriate endotracheal tube size, cuff design, lack of airway humidity, trauma during insertion and suctioning, high anesthetic gas flow rates and manipulation of the airway and surrounding tissues are just a few of the numerous factors causing respiratory tract complications in the perioperative period. Aim: To determine complications of endotracheal intubation with laryngeal mask airway in patients under general anesthesia. Patients & Methods: 200 adult participants were enrolled in the LMA and ETT group male and female age range (18-60 years old) who were a candidate for elective surgery and were in classes 1 and 2 of ASA, Participated in this study. Postoperative complications, including cough, sore throat, bloody ETT&LMA, laryngospasm, delayed extubation, and re-intubation, also assessed cardiovascular difficulty in all patients before and after insertion of ETT & LMA. Analysis of data by spss v.25. Results: Cases of cough, sore throat, bloody ETT&LMA, laryngospasm, delay extubation, and re-intubation in the LMA group were less than in the ETT group and showed no significant difference (P>0.05). In cardiovascular complications, when compared before and after intubation of two groups (ETT&LMA) showed no significant difference in each group(p>0.05). Conclusion:  In this trial, the addition of both the LMA and ETT resulted in a substantial hemodynamic response that included an increase in H.R and ETCO2, Additionally, it was noted that compared to LMA insertion, laryngoscopy and ETT insertion produce a substantially larger hemodynamic response.
