Careful airway risk assessment and procedural planning are vital to ensure patients' safety during airway management. Patients with known procedural difficulty during previous airway management or new anatomical changes pose challenges and risks. To improve communication and the value of documented information regarding difficult airway management for future clinical encounters, we utilized existing electronic health record functions to develop a "difficult airway Navigator." We describe this tool's creation and implementation, which allows clinicians to readily review past airway information and efficiently create difficult airway notes, bedside signs, flags, and orders.

Goldenhar syndrome, or oculoauriculovertebral dysplasia, represents approximately 10% of craniofacial microsomia anomalies. These patients have a variety of clinical features that are relevant to anesthesia providers, including a high-arched palate, mandibular hypoplasia, micrognathia, and temporomandibular joint (TMJ) malformation. ⋯ Outside of the dental and oral surgery literature, the potential for TMJ ankylosis in Goldenhar patients is seldom emphasized. TMJ ankylosis impacts airway management, and anesthesia providers must be aware of this clinical phenotype when planning the anesthetic care of patients with Goldenhar syndrome.

A central neuraxial block may be difficult to perform in elderly patients with lumbar spine deformities, calcified ligaments, and narrowing of the epidural space. We report a case of difficult epidural needle placement in an elderly patient scheduled for bilateral total knee replacement (TKR). We attempted epidural needle placement many times without success. However, when a modified technique was used, the epidural space was identified easily and confirmed, the epidural catheter was inserted and fixed, and the postoperative epidural analgesia was effective.

Case Reports
Acute Intraoperative Hypoxemia During Right Pneumonectomy-The Heart and Lung Interaction: A Case Report.
A 75-year-old woman with a history of right-upper lobectomy for adenocarcinoma presented for a right completion pneumonectomy due to 2 new fluorodeoxyglucose-avid densities on the remaining lung. After uneventful anesthetic induction and surgical resection with modest blood loss, the patient developed refractory hypoxemia on emergence without significant hemodynamic changes. ⋯ An emergent transesophageal echocardiogram revealed a significant intracardiac shunt due to a patent foramen ovale. Specific cardiorespiratory management to achieve a positive left-right heart pressure gradient resulted in prompt normoxemia and successful extubation.

Snorkel masks have become an option for personal protective equipment (PPE) due to the shortage of air filtration at least 95% of airborne particle (N95) masks as a result of the coronavirus disease 2019 (COVID-19) pandemic. We developed a 3D design of a triheaded adapter that connects a snorkel mask to 3 different National Institute for Occupational Safety and Health (NIOSH)-approved air filtration at least 99% of airborne particles (N99) filters with the aim of improving wearer comfort. We measured the resistance of the new triheaded adapter to be one-third the resistance of the single adapter. Interdepartmental survey of anesthesiologists showed an improvement in perceived comfort when using the triheaded adapter as compared to the single adapter.
