The purpose of this review is to compare old conventional techniques and devices for difficult airway management and new sophisticated techniques and devices. Recent techniques and devices are defined as the American Society of Anesthesiology (ASA) practice guidelines for the management of difficult airway, published in 1992, reviewed in 1993 and updated in 2003. According to ASA, the techniques for difficult airway management are divided into techniques for difficult intubation and techniques for difficult ventilation. ⋯ Airway gadgets are lighted stylets and endotracheal tube guides. The principal conclusion of this review is that utilization of these devices can be easily learned. The technique of indirect laryngoscopy is currently used for managing difficult airway in the operating room as well as for securing the airway in daily anesthesia routine.

Airway management in the intensive care unit (ICU) is a challenging procedure and is frequently associated with life threatening complications. The incidence of difficult intubations ranges from 10% to 22%, depending on the setting and the patients in need of endotracheal intubation. Multiple attempts are often needed to secure the airway. ⋯ Parts of this protocol are appropriate staffing, pre-oxygenation and strategies to avoid cardiovascular complications. In conclusion, high practical skill of airway management is needed in critically ill patients. Monitoring such as capnography and alternative equipment for securing the airway is not just mandatory in the operating room but also in the ICU.

Huge multinodular goiter with mid trachea obstruction: indication for fiberoptic intubation.
Goiter or thyromegaly is one of the most common causes of mid tracheal obstruction (external compression or stenosis), which may be associated with difficult larynx visualization and/or difficult airway management, depending on the goiter size, type and ingrowth into the surrounding tissue. Iodine deficiency disorders are still one of the most common causes of goiter in the population of the African continent. These patients with goiter generally present for medical examination at an advanced stage of the disease. ⋯ Only two predicting factors for difficult airway assessment were identified in these patients: cancerous goiter (especially if compressive signs are present) and Cormack and Lehane grade III/IV. The indication for fiberoptic intubation is tracheal compression or initial tracheal stenosis. Conventional tracheostomy has to be performed in goiter patients with identified tracheomalacia and/or high degree or tracheal stenosis.

The number of indications for lung collapse during different procedures is rising. Difficult upper airway is more often encountered with the need for single lung ventilation. ⋯ An alternative technique is exchanging the single-lumen for a double-lumen tube using an airway exchange catheter. When there is a tracheostomy in place, an independent bronchial blocker is recommended.

The Fourth National Audit Project (NAP4) was set up by the Royal College of Anaesthetists and Difficult Airway Society to provide an insight into major complications of airway management in the United Kingdom. The NAP4 found that one serious airway complication such as death, brain damage, the need for surgical airway or unexpected intensive care admission, was reported for every 5500 general anaesthetics. Most of the events happened during daytime to a senior experienced clinicians. ⋯ Awake fibreoptic intubation was indicated and not performed in a significant number of reported incidents. Thirty percent of serious airway complications were associated with extubation or removal of laryngeal mask airway at the end of anaesthesia. The findings of the NAP4 have the potential to significantly influence airway management practice of all anaesthetists irrespective of where in the world they practice anaesthesia.
