Thus, it is not suitable for managing trauma patients. However, it could enable ventilating the patient until definitive airway is achieved, functioning in bridging the period of early treatment. Combitube (esophageal-tracheal twin-lumen airway device) is inserted blindly. Yet, tissue damage and disruption of the anatomy increase the risk NVP-BSK805 cell line of false route and further damage to the airway. Furthermore, Combitube insertion is associated with serious complications to the upper aerodigestive tract, as was demonstrated with its use in the pre-hospital setting, such as esophageal laceration and perforation, tongue oedema,

vocal cord injury, tracheal injury, aspiration pneumonitis and pneumomediastinum [30]. Surgical Airway Performing a cricothyrotomy

or tracheotomy under local anaesthesia is a relatively safe option for managing the airway [31]. However, this approach has its drawbacks. This procedure could be uncomfortable or even painful for the patient, who is already experiencing severe pain and emotional Torin 1 in vivo stress. Tracheotomy by itself carries a 5% risk of complications, such as haemorrhage or pneumothorax [32]. Nevertheless, if the maxillofacial trauma is extensive and requires maxillo-mandibular fixation for several weeks or if prolonged mechanical ventilation is probable, surgical airway may be the best option in such cases. The surgical approach is also used as an emergency salvage procedure, when other options have failed [33]. Direct Laryngoscopy Last but not least lies the classic approach of direct laryngoscopy. This simple and straightforward approach to the airway may be successful in the hands of experienced personnel, though the risk of losing grip on the airway is high. Thus, this approach learn more should be reserved for selected slim patients with good surface

anatomy of the neck, where urgent cricothyrotomy or tracheotomy is feasible, and when an ENT specialist is ready to perform. Post-operative Management The patient with a difficult airway is also at high risk for complications in the post-operative period. Following surgery, mucous membranes are oedematous, soft tissue is swollen and the air O-methylated flavonoid pathway may be compressed. Neck expandability is relatively low and even a small haemorrhage in the region could result in airway compromise. The risk of airway-related complications during the peri-operative period was studied by Peterson et al [4]. They analyzed the American Society of Anesthesiologists Closed Claims database to identify the patterns of liability associated with the management of the difficult airway. They found that complications arose throughout the peri-operative period: 67% upon induction, 15% during surgery, 12% at extubation, and 5% during recovery.
