Brief summary

Difficult airway is one of the main causes of morbidity and mortality in patients who will undergo surgical intervention. Therefore, many devices and algorithms have been developed for the management of difficult airway. This prospective randomized clinical trial compared two methods of difficult intubation, one using the Frova intubation catheter and the other using a non-channelled McGrath videolaryngoscope.49 patients who have ASA score I-III and who will undergo optional operation under general anesthesia and whom airway management process was difficult cases were involved in the research.

Interventions

Patients were undergoing elective surgical procedures requiring tracheal intubation, and had been involved in at least one intubation attempt that had been deemed unsuccessful and was performed by an anaesthetist who has at least three years of experience were randomized to tracheal intubation with the Macintosh laryngoscope (size 3 blade in females; size 4 in males) used with the Frova intubation catheter (Group F) or the McGrath VL (Group V). In cases when intubations could not be carried out

Patients were undergoing elective surgical procedures requiring tracheal intubation, and had been involved in at least one intubation attempt that had been deemed unsuccessful and was performed by an anaesthetist who has at least three years of experience were randomized to tracheal intubation with the Macintosh laryngoscope (size 3 blade in females; size 4 in males) used with the Frova intubation catheter (Group F) or the McGrath VL (Group V). In cases when intubations could not be carried out with the chosen device at the third attempt by an anaesthetist with at least three years of experience, the device was considered to be unsuccessful and intubation was attempted with the second device. When this method also proved unsuccessful, airway management based upon the difficult airway algorithm was maintained. As a third method, the combined use of both devices or intubation with a fibreoptic bronchoscope was preferred.

Inclusion criteria

We studied 50 American Society of Anesthesiologists (ASA) physical status I–III patients, aged 18-65. These cases were undergoing elective surgical procedures requiring tracheal intubation and general anaesthesia, and had been involved in at least one intubation attempt that had been deemed unsuccessful and was performed by an anaesthetist who has at least three years of experience.

Exclusion criteria

Patients who were pregnant, emergency cases, those younger than 18 years, those who had gastroesophageal reflux and delayed gastric emptying, and patients with severe pulmonary disease were excluded.
