Airway management in "tubeless" spontaneous-ventilation video-assisted thoracoscopic tracheal surgery: a retrospective observational case series study

[Anesthesia and Surgery of the Trachea]

This article aims to review the current anaesthetic management of tracheal resections.Apart from the "traditional" approach of induction of general anaesthesia with conventional tracheal intubation and cross-field intubation or jet ventilation during the resection phase, there has lately been a trend towards less invasive techniques.Regional anaesthesia, laryngeal mask airways and preservation of spontaneous ventilation are among the new anaesthetic approaches. Current data suggest potential advantages compared with conventional tracheal intubation.Extracorporeal membrane oxygenation may provide adequate gas exchange and/or cardiovascular support for complex resections and reconstructions. In addition, it may serve as a reliable "backup" technique, in case of oxygenation difficulties with the use of other devices.Given the vast spectrum of different anaesthetic approaches to tracheal surgery, interdisciplinary planning is essential to identify the optimal technique on a case-by-case basis. During that process, the localisation and consistency of the airway lesion, comorbidities and the functional status of the respiratory system and specific surgical approach need to be taken into account.As there is a lack of high-quality data, evidence-based comparisons of different anaesthetic techniques are not possible.
