The incidence of hypoxemia during gastrointestinal endoscopy sedation is high, but there is still a lack of perfect prediction model of hypoxemia, which often leads to unpredictable respiratory complications. In order to ensure the safety of gastrointestinal endoscopy sedation and make emergency plans in advance, a better diagnostic model is urgently needed to help assess the risk of hypoxemia in patients undergoing the process and make early intervention measures. Facial photography is a simple and feasible measure that can show the facial soft tissue and structure of bone. The purpose of this study is to explore whether facial photography combined with other clinical indicators can build a prediction model of hypoxemia during gastrointestinal endoscopy sedation.
This study aimed to identify the effect of oxygen reserve index monitoring on the occurrence of oxygen desaturation (<90%) in pediatric patients undergoing airway surgery.
The investigators' goal is to perform an observational cohort study investigating the use of oxygen reserve index (ORi) in patients undergoing elective thoracic surgery and one-lung ventilation (OLV). For this purpose, ORi values are recorded and compared to the other collected hemodynamical and oximeter parameters. The primary hemodynamic parameters include heart rate (HR) and blood pressure (BP), while; oximeter device-related parameters include peripheral oxygen saturation, perfusion index (PI), and pleth variability index (PVI). The investigators' secondary goal is to investigate relationships between these hemodynamical and oximeter parameters using statistical analysis methods.
The aim of this study to evaluate the patients who underwent controlled hypotensive anesthesia under standardized depth of anesthesia with total intravenous anesthesia or inhalation anesthesia; preoperative and 30. ,60. ,120. second of intraoperative period blood HIF 1a, TAS, TOS measurement and to investigate tissue hypoxia secondary to hypotensive anesthesia and the changes of the mediators at the tissue level and which hypotensive anesthesia technique is related.
The aim of this study to evaluate the patients who underwent controlled hypotensive anesthesia under standardized depth of anesthesia; preoperative and postoperative blood HIF 1a, TAS, TOS measurement and cerebral perfusion evaluation with NIRS and to investigate tissue hypoxia secondary to hypotensive anesthesia and the changes of the mediators at the tissue level and which blood pressure parameters are related.
