A Comparison Of The Double-lumen Tube With The Torque Control Blocker Univent Tube

Techniques for One - lung ventilation ( OLV ) can be accomplished in two different ways. The first method involves the use of a double-lumen endotracheal tube ( DLT ).The second method involves blockade of a mainstem bronchus to allow lung collapse distal to the occlusion ( bronchial blocker). Although the DLTs are the most common devices used during lung separation techniques, they are still some pitfalls. Thetorque control blocker univent tube (TCBU) is one of the devices used in bronchial blocker technique, and in some specific clinical situations it can offer more advantages over the DLT. Because the TCBU is a new bronchial blocker, there are few study to report its effectiveness compared with DLT in one-lung ventilation during elective thoracic surgical cases. Therefore, in this study, a prospective, randomized trial was designed to compare the DLT with the TCBU to determine whether there were objective advantages of one over the other during OLV.ObjectiveThere are few study about comparing the DLT with the TCBU. The objective of this study is to compare the DLT with the TCBU and to determine whether there are objective advantages of one over the other in one-lung ventilation during elective thoracic surgical cases.Materials and Methods60 patients needing one-lung ventilation during elective thoracic surgical cases were randomly divided into Group D and Group U. The patients in Group D (n=30) were intubated with Double-lumen Tube and who in Group U (n=30) were intubated with TCBU. The following variables were recorded and compared: 1) time required for intubation and position each tube, 2) ration of successful blind intubation, 3) increase in airway peak pressure (PIP), 4) frequency of malpositions, 5) number of times that the fiberoptic was achieved, 6)surgical exposure, and 7) frequency of sore throat or hoarseness.ResultsStatistical difference were found in increase of PIP and frequency of sore throat (p < 0.05). No statistical difference were found in the time required to intubation and position each tube, the ration of successful blind intubation, the frequency of malpositions, the number of times that thefiberoptic was achieved and the surgical exposure (p > 0.05).ConclusionTCB univent applied for one-lung ventilation is as good as DLT, and in some specific clinical situations it can offer more advantages over the DLT.
