Current practice of thoracic anaesthesia in Europe – a survey by the European Society of Anaesthesiology Part I – airway management and regional anaesthesia techniques

Background The scientific working group for “Anaesthesia in thoracic surgery” of the German Society of Anaesthesiology and Intensive Care Medicine (DGAI) has performed an online survey to assess the current standards of care and structural properties of anaesthesia workstations in thoracic surgery. Methods All members of the European Society of Anaesthesiology (ESA) were invited to participate in the study. Results Thoracic anaesthesia was most commonly performed by specialists/board-certified anaesthetists and/or senior/attending physicians. Across Europe, the double lumen tube (DLT) was most commonly chosen as the primary device for lung separation (461/ 97.3%). Bronchial blockers were chosen less frequently (9/ 1.9%). Throughout Europe, bronchoscopy was not consistently used to confirm correct double lumen tube positioning. Respondents from Eastern Europe (32/ 57.1%) frequently stated that there were not enough bronchoscopes available for every intrathoracic operation. A specific algorithm for difficult airway management in thoracic anaesthesia was available to only 18.6% (n = 88) of the respondents. Thoracic epidural analgesia (TEA) is the most commonly used form of regional analgesia for thoracic surgery in Europe. Ultrasonography was widely available 93,8% (n = 412) throughout Europe and was predominantly used for central line placement and lung diagnostics. Conclusions While certain „gold standards “are widely met, there are also aspects of care requiring substantial improvement in thoracic anaesthesia throughout Europe. Our data suggest that algorithms and standard operating procedures for difficult airway management in thoracic anaesthesia need to be established. A European recommendation for the basic requirements of an anaesthesia workstation for thoracic anaesthesia is expedient and desirable, to improve structural quality and patient safety.

Managing Known Difficult Airways in Obstetric Patients Using a Flexible Bronchoscope and IRRIS: A Case-Illustrated Guide for Nonexpert Anesthesiologists, without Surgical Backup

Pregnancy is associated with anatomical and physiological changes leading to potential difficult airway management. Some pregnant women have known difficult airways and cannot be intubated even with a hyperangulated videolaryngoscope. If neuraxial techniques are also impossible, awake tracheal intubation with a flexible bronchoscope may be one of the few available options to avoid more invasive techniques. The Infrared Red Intubation System (IRRIS) may help nonexpert anesthesiologists in such situations and may enhance the chance of successful intubation increasing safety for the mother and the fetus, especially in hospitals without the ear, nose, and throat surgical backup.

Difficult Airway Management in Pediatric with a Large Cystic Hygroma Colli Undergoing One-Stage Excision Surgery

Background: A large cystic hygroma colli is a complicating factor in airway management in pediatric. Proper preparation, planning, and anticipation can reduce the risk of complications, morbidity, and mortality during difficult airway management. The fundamental principle of difficult airway management is to maintain adequate oxygenation and avoid hypoxemia by maintaining spontaneous ventilation. Case: A 22-month-old girl, weighing 9 kg, diagnosed with a large cystic hygroma colli who underwent single-stage excision surgery. Cystic hygroma was experienced since birth and with age, the cysts enlarge to a size of 25 x 17 x 12 cm which extends towards the face and shoulders. The patient did not experience stridor and symptoms of airway obstruction. The chest x-ray reveals no expansion of the cyst into the chest cavity and showed minimal tracheal deviation to the right. The difficult airway management was accomplished while maintaining the patient's spontaneous breathing. Sedation and analgesia obtained with intravenous administration of dexmedetomidine, ketamine, and nebulized lidocaine. A video laryngoscope is used to facilitate intubation. Awake extubation was performed after confirming that there was no risk of complications of laryngeal edema, laryngeal nerve injury, and tracheomalacia using a cuff-leak test. Conclusion: Maintaining spontaneous breathing, optimal levels of sedation and analgesia by administering dexmedetomidine, ketamine, and nebulizing lidocaine, and the use of a video laryngoscope can provide successful management of difficult airways due to a large cystic hygroma colli in pediatric patients.

Current treatment of difficult airway: a practical review of advanced techniques for airway management

The airway by definition is a conduit through which the air passes; or it is the route by which the air travels from the nose or mouth to the lungs. An exhaustive review was performed with the available literature using the PubMed, ScienceDirect, Scopus and Cochrane databases from 2009 to 2021. The search criteria were formulated to identify reports related to difficult airway management. To allow controlled ventilation, the airway must meet two characteristics in priority order, be permeable and airtight. In assessing risk, in addition to looking for predictors of difficult airway, it was important to understand the global clinical circumstances. Faced with a patient with a difficult airway, decision-making must be agile and correct since any decision can modify the clinical outcome.

Unanticipated Difficult Airway Management in a Trauma Partient with Severe Ankylosing Spondylitis

Ankylosing Spondylitis is a debilitating chronic arthropathy that affects multiple joints. Anaesthesiologists face significant challenges when dealing with the airway implications of this disease, especially when it is unanticipated that a difficult airway may be encountered. This case describes a 42-year-old trauma victim who required an emergency denitive trachea at his ward. Ankylosing Spondylitis and complex airway anatomy led to his intubation failure. He was eventually given an emergency surgical tracheostomy. The successful management of a difficult airway was possible thanks to the appropriate use of modern airway adjuncts as well as workplace soft skills.
