Abstract
Airway management is critical during general anesthesia as anesthetized patients cannot maintain an adequate airway independently. Traditional methods like direct laryngoscopy (DLS) and endotracheal intubation, though effective, are associated with significant hemodynamic responses and potential complications. The Intubating Laryngeal Mask Airway (ILMA) offers a promising alternative, potentially minimizing these adverse effects. This randomized, prospective, double‐blinded study included 60 patients aged 18‐60 years, ASA grade 1 and 2, scheduled for surgery under general anesthesia. Patients were divided into two groups: one intubated using ILMA and the other using DLS with a Portex cuffed endotracheal tube. The ease of intubation, intubation time, success rate, hemodynamic responses upper airway morbidity were assessed. Hemodynamic parameters, including systolic and diastolic blood pressure (SBP, DBP) and heart rate (HR), were recorded at baseline, post‐intubationat 1, 35 minutes intervals. Upper airway morbidity was evaluated postoperatively at 2 and 24 hours. The mean age was 32.23 years in the ILMA group and 34.3 years in the DLS group. The groups were comparable in demographic characteristics. Tracheal intubation success rates were 100% in both groups, with 90% first‐attempt success in the DLS group and 83.3% in the ILMA group. The mean intubation time was significantly longer for the ILMA group (63.66±14.10 seconds) compared to the DLS group (21.63±3.61 seconds). Both groups exhibited increased SBP, DBPHR immediately post‐intubation, with no significant differences between groups. However, MAP and DBP were significantly higher in the DLS group at 5 minutes post‐intubation. The ILMA group showed a higher incidence of swallowing difficulty postoperatively, but other complications such as sore throat and hoarseness were similar between groups. The ILMA offers comparable ease of intubation and success rates to DLS but requires a longer intubation time and is associated with higher incidences of certain postoperative complications. While ILMA may be advantageous in minimizing hemodynamic responses, further studies are needed to optimize its use and reduce associated morbidity.
