Filter by:In thoracic surgery, one-lung ventilation using a double-lumen tube (DLT) is often performed to protect dependent lung and provide comfortable surgical conditions. However, serious complications and adverse events can be encountered during DLT placement. One of the most important steps to avoid these drawbacks is to choose the appropriate size of DLT. The width of the trachea can be measured by using different imaging methods such as computed tomography (CT) and ultrasonography (US) to predict the appropriate DLT size. CT can also contribute to the proper placement of DLT by giving us the length of the trachea and main bronchi. In this study, we hypothesized that the size of the DLT can be determined more accurately by measuring the trachea diameter by using US and CT before DLT intubation. At the same time, we aimed to determine whether the evaluation of tracheobronchial anatomy with CT would contribute to the placement of DLT at a more appropriate level.
A prospective descriptive study of the use of an individualized capnography to each lung in the context of one-lung ventilation achieved with a double-lumen tube. - Pilot project and proof of concept Brief Summary: - One study suggests a way to predict possible events of hypoxemia (Sat O2 < 90%) during one lung ventilation (OLV) with the use of two individualized capnography devices on each lung during two-lung ventilation before inducing OLV. - In addition, a recent presentation in the 2021 Thoracic Anesthesia Symposium suggested possible benefits of the use of a capnography device on the non-ventilated lung in the detection of air leaks around the bronchial cuff. - The same presentation demonstrated the utility of EtCo2 measurement to determine the achievement of complete lung collapse. With these previous demonstrations, the use of an individualized capnography for each lung can potentially describe different steps during thoracic surgery. Therefore, a descriptive prospective study on patients that require thoracic surgery with use of a double lumen tube is proposed to verify the feasibility of dual capnography during OLV. The use of two different devices, randomized during our study, will also help to identify the impact of different air aspiration levels on our measures. Such results will allow to put forward prospective projects to help to optimize OLV during thoracic surgeries.
How to quickly expose glottis and accurately insert double luminal tracheal tube in patients with difficult airway in thoracoscopic surgery has become an urgent problem in anesthesia induction.This study through the double cavity bronchial tube visual laryngoscope intubation with open mouth and electronic video laryngoscope used in combination, to explore whether can shorten the glottis exposure, improve the success rate of the double lumen tube intubation will reduce pharyngeal damage, reduce intubation hemodynamic fluctuations, in order to improve the glottis appeared difficult patients with bronchial intubation success rate to provide the reference.
Along with the technological advances in medicine, videolaryngoscope is the most commonly preferred technique for intubation with double lumen tube. The use of Storz C-MAC D Blade and McGrath MAC X3 Blade videolaryngoscope were compared in intubation of single lung ventilation patients who underwent chest surgery in terms of duration of intubation, hemodynamic response and intubation-induced complications.
Anatomical variations of right main bronchus have been discouraged anesthesiologists' use of right-sided double lumen tubes to facilitate one-lung anesthesia. However, there are absolute indications of right-sided DLTs surgically, such as left pneumonectomy or in cases with left main endobronchial lesions. With recent advances of 3-dimensional spiral CT reconstruction technique, the investigators conducted this retrospective study to measure accurate length of right and left main bronchus and the angle between the center of the right main bronchus and right upper lobe orifice in axial image to help choosing and further manufacturing right-sided double-lumen tubes.
One lung ventilation (OLV) has become a standard procedure for the vast majority of interventions in pulmonary surgery. It is used in both techniques: thoracotomy and videothoracoscopy (VATS). OLV can be provided by double lumen tube (DLT) with or without the hook. In our study the investigators want to find out if there is any advantage with one or another.
