Airway Management Through a Facial Defect Resulting From Noma (Orofacial Gangrene): A Case Report.
At a rural district hospital in Burundi, a 3-year-old severely malnourished girl with Noma presented to the operating room for placement of a gastrostomy tube. The child had a large left-sided facial defect as well as trismus. ⋯ Given that the hospital has no fiberoptic bronchoscope, direct laryngoscopy and intubation were performed directly through her facial defect. After securing the airway, the surgery proceeded without difficulty.

In performing pulmonary endarterectomy (PEA) for a patient with chronic thromboembolic pulmonary hypertension (CTEPH), we encountered methemoglobinemia that was unmasked by hypothermia while on cardiopulmonary bypass (CPB). The patient on dapsone therapy for antiphospholipid antibody syndrome had developed acquired methemoglobinemia that went undiagnosed because her cyanosis was believed to be due to CTEPH and the resulting ventilation-perfusion (V/Q) mismatch. Although pharmacological triggers for methemoglobin are well known, causation by hypothermia is not described. Monitoring saturation while on CPB was challenging because of nonpulsatile blood flow but was overcome using cerebral oximetry.

We present 4 cases of dorsal root ganglion stimulation lead fracture. In these cases, the surgical technique involved (1) traversing fascial layers for placement of leads via a Tuohy needle in the upper low back, (2) subcutaneous tunneling from the implantable pulse generator site to the lead puncture site without dissecting below the superficial fascial plane at the puncture site, and (3) connection of the lead/extension with the generator. All fractures occurred adjacent to the original lead puncture site. These cases suggest lead entrapment within the membranous fascial plane, with tension on a thin lead, is a mechanism underlying lead fracture.

Patients with Pierre Robin sequence present with numerous anatomical abnormalities that make mask ventilation and tracheal intubation challenging. In this case series, we describe a unique way to overcome upper airway obstruction with the placement of a supraglottic airway in 4 children with Pierre Robin sequence followed by flexible bronchoscopic nasotracheal intubation. This new approach is proven to be a successful method to overcome severe upper airway obstruction, provide continuous oxygenation, and allows nasotracheal intubation for intraoral procedures.
