[Intraoperative exchange of the endotracheal tube using the Cook C-CAE airway exchange catheter].

The Cook airway exchange catheter is mainly used in ICU patients to exchange endotracheal tubes. We report three cases where this device was used during anaesthesia in patients with damaged tubes in critical circumstances (oropharyngeal bleeding, head and neck surgery). It allowed a fast and atraumatic exchange of the tubes.

[-The clinical use of the cuffed oropharyngeal airway (COPA)-].

Objective: To assess the performance of the COPA device during general anaesthesia.

Study Design: Prospective, clinical, open study.

Patients: Eighty patients scheduled for short elective surgical procedures under general anaesthesia not requiring tracheal intubation.

[Cervicofacial cellulitis of dental origin and tracheal intubation].

Objectives: To evaluate the difficulty of intubation in relation with the localisation and spread of cervico-facial cellulitis of odontogenic origin and to recognize the optimal technique of intubation in such circumstances.

Study Design: Prospective clinical open study.

Patients: Hundred patients, including 16 children, undergoing surgical drainage of a cervico-facial cellulitis of odontogenic origin under general anesthesia were studied.

Intermittent left bundle branch block revealed during anaesthesia.

Intermittent left bundle branch block is uncommon. During anaesthesia,, left bundle branch block may be related to hypertension or tachycardia and its occurrence makes the diagnosis of acute myocardial ischaemia or infarction difficult. Patients with intermittent left bundle branch block often develop established left bundle branch block, which may represent an earlier state of ischaemic heart disease.
