Difficult airway management patterns among attending anaesthetists practising in Israel

Survey of Current Difficult Airway Management Practice

BACKGROUND

Even for the most experienced anesthesiologists "can't ventilate can't intubate" scenario in difficult airway management is challenging, and although rare it is life-threatening.

AIM

The aim of this survey was to analyse the current practice of difficult airway management at our University teaching hospital.

MATERIAL AND METHODS

A ten-question-survey was conducted in the Tertiary University Teaching Hospital "Mother Theresa", Clinic for Anesthesia, Reanimation and Intensive Care. The survey included demographic data, experience in training anaesthesia, practice in management of anticipated and non-anticipated difficult airway scenario, preferable equipment and knowledge of guidelines and protocols. Responses were noted, evaluated and analysed with the SPSS statistical program.

RESULTS

The overall response rate was very good; 94.5% answered the survey. During the assessment of the level of comfort with diverse airway equipment, there was diversity of answers due the experience of anaesthesia training, although the most frequent technique among all responders for anticipated difficult intubation was video laryngoscopy (48%). As for non-anticipated difficult intubation when conventional techniques failed to secure the airway most of the responders answered that they used supra-gothic airway device - laryngeal mask (38%) as a rescue measure.

CONCLUSION

Airway assessment, adequate training, experience, and availability of essential equipment are the pillars of successful airway management.

Current practice of difficult airway management: A survey

BACKGROUND AND AIMS

Difficult airway (DA) management depends on both training and actual usage of the various approaches in the event of difficulty. The aim of the study was to assess how well the anaesthesiologists are equipped to deal with DA situations. The current practice preference of DA management was also assessed.

METHODS

A questionnaire was distributed in a continuing medical education (CME) programme dedicated to DA and responses were noted and analysed, using Statistical Package for Social Sciences (SPSS) version 18.

RESULTS

The response rate was 73%. Airway assessment was performed by majority. Sixty eight percent consultants and 47% residents were well aware of the American Society of Anesthesiologists' DA algorithm. 67% consultants and 65% residents attended at least one CME on DA in the previous 5 years. There was an overall deficiency of video laryngoscopes, retrograde intubation and cricothyrotomy sets. Most of the respondents were comfortable in using supraglottic airway devices (SGADs). In anticipated DA, the preferred choice of management for junior doctors was attempting conventional method once and awake fibreoptic bronchoscopy (FOB) for the experienced. In unanticipated DA, most of the residents and consultants opted for SGAD. Extubation strategy was similar for both. Thirty four percent of respondents experienced a 'cannot intubate-cannot ventilate' situation at least once.

CONCLUSION

Our survey showed that most respondents performed routine pre-operative airway assessment. A good armamentarium of airway gadgets should be made available in hospitals. Further training in techniques like video laryngoscopy, FOB or cricothyrotomy are essential.

Airway management practices at German university and university-affiliated teaching hospitals--equipment, techniques and training: results of a nationwide survey

BACKGROUND

Until recently, Germany did not have national airway management guidelines. This survey collected comprehensive data on departmental airway management practices from German teaching institutions to identify weaknesses, and the results are presented here. German national airway guidelines were formulated by an expert group on the basis of these data and the current evidence in the literature.

METHODS

Questionnaires were mailed to the directors of 452 university and university-affiliated anaesthesia departments. They were asked to respond to 39 questions on the use of particular equipment and techniques, management of the difficult airway and training in airway management.

RESULTS

Two hundred and twelve questionnaires were returned. Many alternative devices for endotracheal intubation, such as the Bullard laryngoscope, the Bonfils laryngoscope and the Trachlight, are not used in the majority (80%) of departments. Thirty-six per cent of departments do not have difficult airway carts. No departmental difficult airway management plan is used in 22% of departments. Patients are not provided with written information on their personal airway management difficulties in 14% of departments. Structured training in the form of block rotation is offered in only 29-40% of departments. Although trainees perform fibreoptic intubation (FOI) in most departments, appropriate training in FOI is not available in some departments (8%).

CONCLUSION

There are deficits in various areas of airway management, in particular training and the use of algorithms. International guidelines and recommendations are not followed by a large number of German teaching institutions. The provision of German national airway guidelines should improve this situation.
