Availability and organization of difficult airway equipment in Swedish hospitals: A national survey of anaesthesiologists

BACKGROUND

Airway complications account for almost one third of anaesthesia-related brain damage and death. Immediate access to equipment enabling rescue airway strategies is crucial for successful management of unanticipated difficult airway situations.

METHODS

We conducted a nationwide survey of Swedish anaesthesiologists to analyse availability and organization of difficult airway trolleys (DATs), and multiple factors pertaining to difficult airway management, to highlight areas of potential improvement.

RESULTS

Six hundred and thirty-nine anaesthesiologists completed the 14-item survey. Whereas DATs were almost ubiquitous (95%) in main operating departments of hospitals, prevalence was low in remote anaesthetizing locations (20.3%) and electroconvulsive therapy units (26.6%). Approximately 60% of emergency departments had a DAT. Immediate (within 60 seconds) access to videolaryngoscopes in all units where general anaesthesia is conducted was reported by 56.8%. Almost half of anaesthesiologists reported that all DATs at their workplace were standardized. Forty-six per cent reported that the DATs were organized according to a difficult airway algorithm; almost 90% believe that such an organization can impact the outcome of a difficult airway situation positively. Only 36.2% of DATs contained second-generation supraglottic airway devices exclusively. Most Swedish anaesthesiologists use the Swedish Society of Anaesthesiology and Intensive care Medicine difficult airway algorithm, but almost one fifth prefer the Difficult Airway Society algorithm. Less than half of respondents underwent formal difficult airway training annually.

CONCLUSION

Our results motivate efforts to (a) increase availability of DATs in remote anaesthetizing locations, (b) increasingly standardize DATs and organize DATs according to airway algorithms, and (c) increase the frequency of difficult airway training.

Tracheal extubation of the adult intensive care patient with a predicted difficult airway - a narrative review

Management of the difficult airway is an important, but as yet poorly-studied, component of intensive care management. Although there has been a strong emphasis on prediction and intubation of the difficult airway, safe extubation of the patient with a potentially difficult airway has not received the same attention. Extubation is a particularly vulnerable time for the critically ill patient and, because of the risks involved and the consequences of failure, it warrants specific consideration. The Royal College of Anaesthetists 4th National Audit Project highlighted differences in the incidence and consequences of major complications during airway management between the operating room and the critical care environment. The findings in the section on Intensive Care and Emergency Medicine reinforce the importance of good airway management in the critical care environment and, in particular, the need for appropriate guidelines to improve patient safety. This narrative review focuses on strategies for safe extubation of the trachea for patients with potentially difficult upper airway problems in the intensive care unit.
