Summary

For anatomical and physiological isolation of the lung, a specialized endotracheal tube known as the double lumen tube (DLT) is used. The introduction of DLT into anesthesia can be attributed to Carlen's who brought forth the concept in 1949. Since then the structure of DLT has continuously evolved. Simplistically speaking; the double lumen tube is a co-axial tube i.e. it contains two tubes put together, the tube with the shorter length stays in the trachea whereas the tube with the longer length enters the right or left main bronchus. If the proximal or tracheal cuff is inflated, air entry is permitted into both lungs. However, if the distal or the bronchial cuff is inflated, ventilation is directed into either lung depending on which lumen has been clamped, at the proximal end of the tube. Conventionally the DLTs were made of red rubber and were reusable but now they have been replaced by disposable plastic tubes which make it easy to view any secretions or blood. Also, since the plastic makes for a thin wall it allows the lumen of the tube to be large enough to allow airflow with minimal resistance. Larger lumens also allow passage of suction catheters and fiber-optic bronchoscope which serves the purpose of confirming correct position of the double lumen tube after placement. Tracheal intubation with a DLT may be facilitated by maneuvers such as external laryngeal manipulation (ELM). It is a simple technique which has been used by anesthetists since many years to enable intubation. Various types of video-laryngoscopes (VL) have been found to perform a crucial part in patients with difficult airways McGrath video-laryngoscope - a portable machine - provides a better laryngeal view compared to Macintosh laryngoscopy, involving cases of intubation involving patients with normal or difficult airways. Though the use of VL for DLT placement has been reported, such studies have fallen short of producing the desired quality of evidence that is required to make a clear determination in favor of one method over the other. It is suggested that more work is needed on this in order to create a wider, more reliable data pool.
