ABSTRACT
Pulmonary alveolar proteinosis (PAP) can be due to primary autoimmune and secondary causes, including e-cigarette, or vaping, product use-associated lung injury. We present a 33-year-old male presenting with PAP and a history of vaping. Serum anti-granulocyte-macrophage colony-stimulating factor antibodies were present. Vitamin E (VE), but not VE acetate, was detected in bronchoalveolar lavage. This is the first report of potential association between vaping and autoimmune PAP.
ABSTRACT
The utilization of temporary circulatory support in the form of extracorporeal membrane oxygenation (ECMO) has increased and its indications are expanding. Anesthesiologists may be involved in the care of these patients during the initiation of and weaning off from ECMO, surgical procedures with an ECMO in situ, and transfer of patients on ECMO between the operating theater and intensive care unit. This article addresses the anesthetic considerations and management for explant of veno-arterial ECMO in adults.

BACKGROUND AND AIMS: Fibre-optic intubation (FOI) through supraglottic airway devices (SADs) is useful in the management of the difficult airway. We compared two methods of FOI through seven SADs in a randomised crossover manikin study to assess each device's performance and discuss implications on SAD selection. METHODS: Thirty anaesthetsiologists, 15 seniors and 15 juniors, each performed low skill FOI (LSFOI) with seven SADs using both 'direct' and 'indirect' methods. The order of method and device used were randomised. The primary end point was success rate of intubation; secondary end points were time taken for intubation, incidence of difficulties with direct and indirect LSFOI and operator device preference. Statistical analysis was with univariable analysis and comparison of proportions. RESULTS: Data from six devices were analysed due to a protocol breach with one SAD. There was no difference in intubation success rate across all SADs and intubation methods. Intubation time was significantly shorter in AmbuAuragain than other SADs and shorter with the direct method of LSFOI than the indirect method (mean difference of 6.9 s, P = 0.027). Ambu Auragain had the least SAD and bronchoscope-related difficulties. Seniors had significantly shorter mean intubation times than juniors by 11.6 s (P = 0.0392). The most preferred SAD for both methods was AmbuAuragain. CONCLUSION: Low skill FOI consistently achieves a high intubation success rate regardless of experience, choice of method, or SAD used. SAD design features may significantly affect the performance of low skill FOI.
ABSTRACT
We report the case of a 59-year-old woman with mitochondrial myopathy who underwent elective laparoscopic cholecystectomy and hemorrhoidectomy, and we review the literature discussing general anesthesia for adults with mitochondrial myopathy. Our management technique avoids neuromuscular-blocking drugs and uses a modified awake intubation method not previously described in such patients. We hope to improve patient safety by discussing evidence-based anesthetic concerns and complications specific to these uncommon patients and aid practitioners in devising a suitable anesthetic plan.
