ED Airway Management in the Netherlands.

Overview

Airway management is one of the resuscitative procedures patients may undergo in the Emergency Department (ED). While this is a high risk procedure, to date there is no data available on airway management practices, success or safety in EDs in the Netherlands. The objective of this study is to describe airway management in the Netherlands.

Airway management is the planning, preparation and execution of medical interventions to maintain a patients airway and thereby maintaining or supporting the patients respiration. While the term is used for a range of techniques, the technique that is most studied and relevant in the emergency department (ED) is endotracheal intubation. Endotracheal intubation is an important procedure in emergency care with a broad range of indications. Examples are altered mental status due to trauma, intoxication or stroke, respiratory failure due to respiratory diseases such as pneumonia and airway obstruction due to trauma or allergic reactions. While endotracheal intubation can be a lifesaving intervention, it can also result in complications such as airway trauma, aspiration, hypoxia, hypotension and cardiac arrest . Peri-intubation adverse events have been reported in 12-26% of intubations. For example, Alkhouri et al reported that ED intubations were complicated by desaturation (11.9%), hypotension (7.1%), aspiration (2.7%) and cardiac arrest (1%). These complications are relatively more frequent in the ED than in the operating room, and they also seem to result in more harm. One study reported a 38-fold higher incidence of brain damage or death as result of an airway event in the ED compared to the operating room. These differences are most likely caused by multiple factors, such as anatomical and physiological difficulties of airway management due to the underlying pathology of the ED patient, training of providers and available equipment in the ED. Valuable information about the practice of airway management in the ED can derived from one of the large national and international ED airway registries. Examples are the National Emergency Airway Registry (NEAR), the Australia and New Zealand Emergency Department Airway Registry (ANZEDAR) and the Japanese Emergency Airway management (JEAN). These registries have described indications, providers, techniques, success and adverse events of airway management in the ED. This data has also provided insights into factors that are related with success of intubation on one hand, and the occurrence of complications on the other. For example, the NEAR registry showed that the use of video laryngoscopy was associated with a higher rate of successful intubations at the first attempt than with direct laryngoscopy in trauma patients and patients with signs of a difficult anatomical airway. In these patients the rate of oesophageal intubation was lower when video laryngoscopy was used. The ANZEDAR registry showed that intubations were more often complicated by hypotension when propofol was given as induction agent and that intubations were less often complicated by hypoxia when apnoeic oxygenation was used. Furthermore, data from these registries also show trends in the practice of airway management. For example, where only the minority of patients in the JEAN registry was intubated using rapid sequence induction (RSI) at the start of the registry, now the majority of patients is intubated using RSI. Video laryngoscopy was increasingly used during the study period in the NEAR and JEAN registries, while in the ANZEDAR registry the use of ketamine as an induction agent has significantly increased throughout the years. All in all, ED registries have provided a valuable contribution to our knowledge of ED airway management. To date, no data has been published about airway management in EDs in the Netherlands. While the aforementioned ED registries do provide information, it is unknown to what extend those findings can be translated to the Netherlands. First of all, there is variation in the practice of airway management between the registries. For example, when comparing induction agents that are used for intubation, there is great variability between ED airway registries. In the NEAR registry etomidate was used in the great majority of intubations, while in the JEAN registry midazolam was used most often. For intubations in the ANZEDAR registry ketamine, propofol and thiopentone were used in approximately equal proportions. Considering the variations between these registries, it is difficult to make assumptions about which drugs are used in the Netherlands for airway management. Furthermore, certain features of ED care in the Netherlands differ from the countries that participated in the registries. In the NEAR, ANZEDAR and JEAN registries the intubations were mainly performed by emergency physicians. However, according to a national survey only a minority of emergency physicians in the Netherlands perform intubations. It is unclear to what extent findings of these ED registries match the current practices of airway management in EDs in the Netherlands. The goal of this study is to provide a compressive overview of airway management practice in Dutch EDs and to provide input for quality assessment, quality improvement and future interventional studies.
