          Abstract

          Background

          In Sweden, airway guidelines aimed toward improving patient safety have been recommended by the Swedish Society of Anaesthesia and Intensive Care Medicine. Adherence to evidence-based airway guidelines is known to be generally poor in Sweden. The aim of this study was to determine whether airway guidelines are present in Swedish anaesthesia departments.

          Methods

          A nationwide postal questionnaire inquiring about the presence of airway guidelines was sent out to directors of Swedish anaesthesia departments (n = 74). The structured questionnaire was based on a review of the Swedish Society of Anaesthesia and Intensive Care voluntary recommendations of guidelines for airway management. Mean, standard deviation, minimum/maximum, percentage (%) and number of general anaesthesia performed per year as frequency (n), were used to describe, each hospital type (university, county, private). For comparison between hospitals type and available written airway guidelines were cross tabulation used and analysed using Pearson’s Chi-Square tests. A p- value of less than 0 .05 was judged significant.

          Results

          In total 68 directors who were responsible for the anaesthesia departments returned the questionnaire, which give a response rate of 92% (n 68 of 74). The presence of guidelines showing an airway algorithm was reported by 68% of the departments; 52% reported having a written patient information card in case of a difficult airway and guidelines for difficult airways, respectively; 43% reported the presence of guidelines for preoperative assessment; 31% had guidelines for Rapid Sequence Intubation; 26% reported criteria for performing an awake intubation; and 21% reported guidelines for awake fibre-optic intubation. A prescription for the registered nurse anaesthetist for performing tracheal intubation was reported by 24%. The most frequently pre-printed preoperative elements in the anaesthesia record form were dental status and head and neck mobility.

          Conclusions

          Despite recommendations from the national anaesthesia society, the presence of airway guidelines in Swedish anaesthesia departments is low. From the perspective of safety for both patients and the anaesthesia staff, airway management guidelines should be considered a higher priority.

          Major complications of airway management in the UK: results of the Fourth National Audit Project of the Royal College of Anaesthetists and the Difficult Airway Society. Part 1: anaesthesia.

          This project was devised to estimate the incidence of major complications of airway management during anaesthesia in the UK and to study these events. Reports of major airway management complications during anaesthesia (death, brain damage, emergency surgical airway, unanticipated intensive care unit admission) were collected from all National Health Service hospitals for 1 yr. An expert panel assessed inclusion criteria, outcome, and airway management. A matched concurrent census estimated a denominator of 2.9 million general anaesthetics annually. Of 184 reports meeting inclusion criteria, 133 related to general anaesthesia: 46 events per million general anaesthetics [95% confidence interval (CI) 38-54] or one per 22,000 (95% CI 1 per 26-18,000). Anaesthesia events led to 16 deaths and three episodes of persistent brain damage: a mortality rate of 5.6 per million general anaesthetics (95% CI 2.8-8.3): one per 180,000 (95% CI 1 per 352-120,000). These estimates assume that all such cases were captured. Rates of death and brain damage for different airway devices (facemask, supraglottic airway, tracheal tube) varied little. Airway management was considered good in 19% of assessable anaesthesia cases. Elements of care were judged poor in three-quarters: in only three deaths was airway management considered exclusively good. Although these data suggest the incidence of death and brain damage from airway management during general anaesthesia is low, statistical analysis of the distribution of reports suggests as few as 25% of relevant incidents may have been reported. It therefore provides an indication of the lower limit for incidence of such complications. The review of airway management indicates that in a majority of cases, there is 'room for improvement'.

            Complications and failure of airway management.

            Airway management complications causing temporary patient harm are common, but serious injury is rare. Because most airways are easy, most complications occur in easy airways: these complications can and do lead to harm and death. Because these events are rare, most of our learning comes from large litigation and critical incident databases that help identify patterns and areas where care can be improved: but both have limitations. The recent 4th National Audit Project of the Royal College of Anaesthetists and Difficult Airway Society provides important detailed information and our best estimates of the incidence of major airway complications. A significant proportion of airway complications occur in Intensive Care Units and Emergency Departments, and these more frequently cause patient harm/death and are associated with suboptimal care. Hypoxia is the commonest cause of airway-related deaths. Obesity markedly increases risk of airway complications. Pulmonary aspiration remains the leading cause of airway-related anaesthetic deaths, most cases having identifiable risk factors. Unrecognized oesophageal intubation is not of only historical interest and is entirely avoidable. All airway management techniques fail and prediction scores are rather poor, so many failures are unanticipated. Avoidance of airway complications requires institutional and individual preparedness, careful assessment, good planning and judgement, good communication and teamwork, knowledge and use of a range of techniques and devices, and a willingness to stop performing techniques when they are failing. Analysis of major airway complications identifies areas where practice is suboptimal; research to improve understanding, prevention, and management of such complications remains an anaesthetic priority.

              Difficult Airway Society Guidelines for the management of tracheal extubation.

              Tracheal extubation is a high-risk phase of anaesthesia. The majority of problems that occur during extubation and emergence are of a minor nature, but a small and significant number may result in injury or death. The need for a strategy incorporating extubation is mentioned in several international airway management guidelines, but the subject is not discussed in detail, and the emphasis has been on extubation of the patient with a difficult airway. The Difficult Airway Society has developed guidelines for the safe management of tracheal extubation in adult peri-operative practice. The guidelines discuss the problems arising during extubation and recovery and promote a strategic, stepwise approach to extubation. They emphasise the importance of planning and preparation, and include practical techniques for use in clinical practice and recommendations for post-extubation care.
