Pre-warming the double-lumen endobronchial tubes to facilitate intubation in incubator: Reply

Comparison of the resistances of double-lumen endobronchial tubes.

The resistance of commonly-used double-lumen endobronchial tubes were measured and a detailed comparison made. Robertshaw tubes were generally found to have a lower resistance than either the Carlens or the White tubes of equivalent size, but this was not so in every case. The White tubes had a disproportionately high resistance associated with the upper lobe orifice when compared with the resi...

Hemodynamic and Humoral Response to Intubation with Double-lumen Endotracheal Tubes Versus Single-lumen Tubes Combined with an Endobronchial Blocker: A Randomized Clinical Trial

Introduction: Insertion of endotracheal tubes, especially large and relatively inflexible double-lumen tubes, provokes cardiovascular and humoral responses which can cause complications. Bronchial blockers, combined with conventional single-lumen tubes (SLT), serve as alternatives to double-lumen tubes (DLT) and may provoke less hemodynamic response. Methods: Forty adults scheduled for elective...

effective bolus dose of sufentanil to attenuate cardiovascular responses in laryngoscopic double-lumen endobronchial intubation

conclusions we found that 0.3 mcg/kg of sufentanil attenuates cardiovascular responses to double-lumen endobronchial intubation without adverse effects. background sufentanil is a potent opioid analgesic frequently used in clinical anesthesia. double-lumen endobronchial intubation induces profound cardiovascular responses in comparison with ordinary endotracheal intubation because of the larger...

Cardiovascular and arousal responses to single-lumen endotracheal and double-lumen endobronchial intubation in the normotensive and hypertensive elderly

BACKGROUND Endotracheal intubation usually causes transient hypertension and tachycardia. The cardiovascular and arousal responses to endotracheal and endobronchial intubation were determined during rapid-sequence induction of anesthesia in normotensive and hypertensive elderly patients. METHODS Patients requiring endotracheal intubation with (HT, n = 30) or without hypertension (NT, n = 30) ...
