Prediction of hypotension during the alveolar recruitment maneuver in spine surgery: a prospective observational study.

Background: Atelectasis can occur in many clinical practices. One way to prevent this complication is through the alveolar recruitment maneuver (ARM). However, hemodynamic compromise can accompany ARM.

The i-gel supraglottic airway device improves airway management during endobronchial ablative therapy under general anesthesia: a case report.

Endobronchial ablative therapy (EAT) in patients with preexisting obstructive airway disease can cause hypoxemia because bronchoscope insertion interferes with ventilation and a low fraction of inspired oxygen (FiO) is essential to avoid airway fire. A man in his early 50s with moderately severe obstructive airway disease was scheduled for EAT for treatment of tracheal papillomatosis. Ventilation and oxygenation would have been difficult because of narrowing of the endotracheal tube by bronchoscopic insertion and a low FiO; therefore, an i-gel supraglottic airway device with a larger inner diameter was inserted.

Postlaryngectomy supraglottic stenosis revealed by three-dimensional computed tomography reconstruction: A case report.

Rationale: Supraglottic stenosis is a rare cause of airway obstruction. It can be induced by radiation, trauma, autoimmune diseases, or caustic exposure, and is often misdiagnosed as asthma. Detailed airway information is necessary to re-establish the normal functioning of the airway.

Transparent and attachable ionic communicators based on self-cleanable triboelectric nanogenerators.

Human-machine interfaces have benefited from the advent of wireless sensor networks and the internet of things, but rely on wearable/attachable electronics exhibiting stretchability, biocompatibility, and transmittance. Limited by weight and volume, wearable devices should be energy efficient and even self-powered. Here, we report practical approaches for obtaining a stably self-cleanable, transparent and attachable ionic communicator based on triboelectric nanogenerators.
