Laryngeal tube

Laryngeal tube is a type of supraglottic airway device used in emergency medicine and anesthesia to provide a secure airway during resuscitation or surgery. It is a simpler alternative to endotracheal intubation and laryngeal mask airway (LMA), and can be used by non-specialist healthcare providers with minimal training.

Design and Function

The laryngeal tube is a flexible, hollow tube made of silicone or PVC, with a cuff at the distal end that is inflated to seal the larynx and prevent aspiration of stomach contents. The proximal end has a connector for attachment to a bag-valve-mask or ventilator. The tube has two lumens: one for ventilation and one for gastric decompression.

Indications

The laryngeal tube is indicated for use in emergency situations where endotracheal intubation is not possible or practical, such as cardiac arrest, respiratory arrest, and severe trauma. It is also used in anesthesia for short surgical procedures where endotracheal intubation is not necessary.

Contraindications

Contraindications for the use of the laryngeal tube include known or suspected esophageal disease, such as esophageal varices or esophageal obstruction, and patients with a full stomach or at risk of aspiration.

Complications

Possible complications of laryngeal tube use include aspiration, laryngospasm, bronchospasm, and trauma to the larynx or esophagus. Proper placement and inflation of the cuff can minimize these risks.
