NCT ID: NCT05778968 Recruiting - Clinical trials for End-tidal Carbon Dioxide

Etco2 Levels on the End-tidal Concentration of Sevoflurane

Start date: February 1, 2023
Phase: N/A
Study type: Interventional

he assessment of adequate levels of anaesthesia traditionally relies not only on a patient's movement but also on the hemodynamic response (or both) to a surgical stimulus

NCT ID: NCT05746949 Completed - Oxygen Clinical Trials

Comparison of the Effects of High-flow Nasal Cannula Oxygen and Jet Ventilation Techniques

Start date: February 18, 2023
Phase: N/A
Study type: Interventional

Endoscopic microsurgical procedures of the larynx (direct examination-bx, microlaryngeal resection) require the anesthesiologist and surgeon to work in the same area throughout the procedure, and while ventilation is provided during the procedure, small diameter endotracheal tubes are preferred to see the surgical area as easily as possible. However, it is sometimes observed that even conventional endotracheal tubes of this diameter make surgery difficult by obstructing the view. On the other hand, apneic laryngoscopy techniques used in upper airway surgeries, such as microlaryngoscopy and laryngotracheal surgery, where the airway is shared by the anesthesiologist and surgeon, have been replaced by safer and controlled high-frequency jet ventilation applications due to the risk of hypoxemia and hypercapnia. In recent years, oxygenation has come to the fore with Transnasal High Flow Insufflation (OptiflowTM - Fischer & Paykel Healthcare, Auckland, New Zealand), an apneic oxygenation method. This randomized study aimed to compare the effects of high-flow nasal oxygen and jet ventilation on oxygenation in patients receiving general anaesthesia for endolaryngeal surgery.

NCT ID: NCT04281589 Completed - Ventilation Clinical Trials

End-tidal Carbon Dioxide Monitoring in Low Tidal Volume Ventilation

ETCO2
Start date: May 7, 2019
Phase: N/A
Study type: Interventional

In cases where there is no ventilation-perfusion problem, the end-tidal carbon dioxide (ETCO2) value is closely associated with partial arterial carbon dioxide pressure (PaCO2); therefore, the PaCO2 value can be estimated using ETCO2 measurements in patients without significant cardiopulmonary disorders. The aim of the investigator's study is to evaluate the reliability of pulmonary ventilation monitoring with ETCO2 value and to investigate at what tidal volume values ETCO2 monitoring provides reliable information.

NCT ID: NCT03932617 Completed - Shock Clinical Trials

Correlation Between Changes in End-Tidal Carbon Dioxide and Stroke Volume Variation Detected by Electrical Cardiometry as A Predictor of Fluid Volume Responsiveness in Hemodynamically Unstable Patients in the Intensive Care

Start date: June 1, 2019
Phase:
Study type: Observational

This study will be conducted to assess the role of end-tidal carbon dioxide (PETCO2) monitoring to predict the fluid volume responsiveness in correlation with stroke volume variation detected by electrical cardiometry in patients with hemodynamic instability.
