Background and Aims:
Ambu

AuraGain™ laryngeal airway (AuraGain) is one of the newer supraglottic airway device introduced in 2014. Cervical spine stabilisation with hard cervical collar makes insertion of supraglottic airways and tracheal intubation difficult. This study was conducted to investigate whether the presence of a cervical collar affects the oropharyngeal sealing pressure (OSP) and fibreoptic view of the glottis (Brimacombe score) in airways secured with the AuraGain.
Methods:
The study was a randomised crossover trial. Thirty five ASA 1-3 patients undergoing elective surgery under general anaesthesia were recruited for the study. In each patient AuraGain was inserted twice in a crossover manner once with and once without a hard cervical collar
in situ
, with the sequence of insertion randomised. During each insertion of AuraGain the OSP, fibreoptic view of the glottis, insertion parameters, ventilator data and complications were noted.
Results:
The mean OSPs in both the groups were similar with no significant difference (29.6 ± 3.7 cmH
2
O without collar and 30.1 ± 3.1 cmH
2
O with collar [
P
= 0.310]). The fibreoptic view of glottis was also similar in both groups. The insertion with collar was more difficult than without collar. The number of attempts for successful insertion was same in both the groups. The time taken for appropriate placement of LMA was significantly prolonged in patients with collar.
Conclusions:
We conclude that the Ambu AuraGain can be used to provide effective ventilation in patients whose cervical spine is immobilised with a hard cervical collar.
Anaesthetic management of tracheal resection and reconstruction in patients with difficult tracheal pathologies, poses unique challenges—such as pre-operative assessment and preparation, the induction of general anaesthesia, airway sharing with surgeons during the intra-operative period while performing resection and reconstruction, emergence from general anaesthesia, and post-operative care. While there are no guidelines on choosing the ideal airway technique for the intra-operative period, we describe a simple-yet-effective airway modality, viz. spontaneous ventilation, as a key airway technique during the crucial open airway phase during tracheal reconstruction.
Left ventricular (LV) thrombus formation is a notorious complication encountered in postmyocardial infarction patients. Such cases, when coming for noncardiac surgery, put the patient at greater risk of embolic events. Anesthesiologists play a pivotal role in the management of such rare and difficult cases. There is sparse evidence on management of such cases for noncardiac surgery. Hence, we would like to share our experience of a young patient with LV thrombus posted for left decompressive craniectomy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
