A&A practice

Perioperative difficult airway management is one of the most challenging tasks encountered by anesthesiologists. Awake intubation is considered the gold standard in securing the anticipated difficult airway. ⋯ We report a case of a monolingual Arabic-speaking patient with a difficult airway who required awake intubation to undergo surgery. Google Translate, a free and accessible translation software application, was used during his awake intubation-we recommend such an approach to be considered to reduce anxiety and facilitate success by providing concise, real-time instruction in the patient's preferred language.

In this case, a 79-year-old male presented with new anteroseptal Q waves and T-wave inversions across the precordial leads following an otherwise uneventful endovascular repair of his thoracoabdominal aortic aneurysm. The patient had no history of cardiac disease and had undergone a dobutamine stress echocardiogram within the preceding 6 months that showed no evidence of inducible ischemia. Nevertheless, routine postoperative electrocardiogram (EKG) revealed new Q waves and T-wave inversions and transthoracic echocardiogram that demonstrated akinesis of the left ventricle (LV) apex with chronic-appearing apical thrombus. We will further discuss preoperative evaluation of cardiovascular risk along with postoperative interpretation of EKG abnormalities.

With the ongoing development of safer anesthesia, pregnant women with cardiac disease are presenting more frequently for cesarean delivery. We report the successful anesthetic management of a 31-year-old parturient, on long-term anticoagulant therapy, who presented with acute cardiac tamponade due to perforation of the left atrium from a dislodged atrial septum defect occluder. The cesarean delivery was followed by temporary repair of the perforation without extracorporeal circulation (EC) due to concerns about excessive postpartum bleeding. The definitive repair of the atrial defect and the perforation were successfully accomplished under (EC) 5 days after delivery.

Ventilation during microlaryngoscopy previously included jet ventilation, microlaryngeal endotracheal tubes, and extended apnea. Historically, apneic oxygenation provided a tubeless field but limited operative time. ⋯ Although few studies have described high-flow nasal cannula for microlaryngoscopy, there remains much to be explored. In this case report, we describe the unique setting of utilizing high-flow nasal cannula in a spontaneously breathing patient to create an optimal tubeless surgical field for both microlaryngoscopy and vocal cord electromyography.

Case Reports
Misinterpretation and Limitations of pEEG Monitoring During Multimodal General Anesthesia: A Case Report.
The adequate titration of hypnotic agents can be achieved using processed electroencephalogram (pEEG) monitors. pEEG monitors with a spectrogram, such as bilateral bispectral index (BIS), are useful because they can show different signatures that suggest the effect of a given drug on brain activity. Multimodal general anesthesia is based on a combination of hypnotic and antinociceptive agents. We report a case of awareness in a patient monitored with bilateral BIS during multimodal general anesthesia. This case illustrates the limitations of the index and the value of the spectrogram in the assessment of hypnosis.
