Completed

• Conditions: Assessment; Difficult Airway Intubation; Preoperative
• Interventions: Device: airtraq; Device: mcgrath mac x-blade; Device: storz c-mac; Device: storz d-blade

Brief Summary

preoperative assessment of difficult airways are the subject of debate. Now, measuring the thyromental distance or evaluating the mallampati score, mandible protrusion or body mass index still not 100% specifically say anything. We compare 4 different video laryngoscopes for preoperative assessment of difficult laryngoscopy.

Detailed Description

preoperative assessment of difficult airways are the subject of debate. Now, measuring the thyromental distance or evaluating the mallampati score, mandible protrusion or body mass index still not 100% specifically say anything. all patients were pre oxygenated with 100% oxygen with nasal canulla during the whole procedure. We administered 0.07 mgr/kg remifentanil for minimum 3 minutes and continue this infusion during the procedure. The patients airway topicalized by 10% lidocaine spray. We enroll 20 patients undergoing elective surgery.

We compare 4 different video laryngoscopes for preoperative assessment of difficult laryngoscopy in the same patient. We evaluate the patient and the instructors satisfaction with the visual analogy scale and the visualization time. Demographic vary,ables and the airway characteristics of patients. We assess the cormack lehane view of these videolaryngoscopes with or without cricoid pressure. and the occurrence of gag reflex as well.
