NCT ID: NCT05906030 Not yet recruiting - Pneumonia Clinical Trials

Diaphragm Dysfunction and Ultrasound Perioperatively

DiaphPeriop
Start date: September 1, 2023
Phase:
Study type: Observational

This study aims at determining whether diaphragm ultrasound examining diaphragm thickening fraction, excursion and density before and after surgery can predict respiratory complications in the postoperative period. Patients scheduled for major elective abdominal, pelvic or vascular surgery will be included in the study and diaphragm ultrasound is performed before surgery and after surgery in the postoperative ward. Physiological parameters, laboratory parameters, data on surgery and anesthesia and comorbidities will be registered. Complications such as pneumonia, desaturation, need for intubation and other respiratory events up to 30 days will be registered and later correlated with the diaphragm measurements.

NCT ID: NCT05825638 Recruiting - COPD Clinical Trials

Evolution of Pulsed Oxygen Saturation During Interval Training Compared to Continuous Training in COPD Patients

Start date: January 10, 2023
Phase:
Study type: Observational

A problem often observed during exercise training is oxygen desaturation exclusively during exercise in some patients. In the case of exercise-induced desaturation, it may be suggested to train these patients in interval training to limit exercise-induced desaturation. Interval training consists of alternating active phases of short duration (often 30 seconds to 1 minute) followed by a short active or passive recovery phase of equivalent duration to the previous phase. Investigators therefore hypothesise that interval training on a cycloergometer or treadmill can limit exercise-induced desaturation in COPD patients. The aim of the study is to observe the evolution of pulsed oxygen saturation between a continuous training session and a interval training session.

NCT ID: NCT05688722 Completed - Surgery Clinical Trials

Head Elevation During Pre-oxygenation Can Delay Desaturation Time

Start date: April 1, 2021
Phase: N/A
Study type: Interventional

This study is a randomized-controlled trial study comparing the association between several degree of head elevation and conventional position during pre-oxygenation to desaturation time in patients undergo endotracheal intubation with general anesthesia

NCT ID: NCT05526768 Completed - Clinical trials for Congenital Heart Disease

Evaluation of VITLS Compared to Traditional Inpatient Monitoring in Cardiac Shunt-Dependent Children

Start date: October 26, 2022
Phase: N/A
Study type: Interventional

We are seeing how well a remote monitoring device that looks like a sticker placed on the chest, under the arm can monitor a child's vital signs including oxygen levels compared to the way that we usually get these measurements. The goal of this study is to see if the new sticker can be used for monitoring patients with cardiac shunt dependent heart conditions from home once they are discharged home. Participating children will be monitored for 6-72 hours with the new sticker in addition to his/her usual hospital monitors so the new sticker device can be compared to our hospital monitors.

NCT ID: NCT05212064 Completed - Hypoxia Clinical Trials

HFNC and Hypoxia/Desaturation During Radiofrequency Ablation Under Moderate Sedation: A Randomized Clinical Trial

Start date: January 1, 2022
Phase: N/A
Study type: Interventional

Background: Propofol based sedated anesthesia was widely used in percutaneous radiofrequency ablation and hypoxia/desaturation is one of the most frequent adverse events during this procedure. No effective methods have been found to prevent hypoxia/desaturation so far. The aim of this study was to evaluate whether the incidence of hypoxia/desaturation was different between the high-flow nasal cannula (HFNC) therapy group (which can provide heated and humidified oxygen up to 60L/minute.) and the nasal cannula group. Methods: In a randomized, prospective and double-blind study,100 patients undergo percutaneous radiofrequency ablation based on propofol sedation were assigned into two groups: the nasal cannula group (O2 [6 L/minute] was supplied via an HFNC) and the HFNC group (O2 [40 L/minute] was supplied via an HFNC). The primary outcome is the incidence of hypoxia/desaturation during surgery. Other adverse events were also recorded.

NCT ID: NCT04976504 Completed - Anesthesia Clinical Trials

Early Warning for Desaturation by Oxygen Reserve Index

Start date: March 1, 2019
Phase:
Study type: Observational [Patient Registry]

During the induction of general anesthesia, the anesthesiologist needs to provide the oxygen supply to meet the patient's needs continuously. In the clinical scenario, the pulse oximeter is used as a standard to monitor hemoglobin oxygen saturation (SpO2) but is limited to assess the oxygenation status beyond the measurement of 100%. The Oxygen Reserve Index (ORi) is a dimensionless parameter between 0 and 1 that is related to real-time oxygenation reserve status. This study was designed to evaluate the duration of warning time for desaturation provided by different ORi alarm triggers during prolonged apnea in surgical patients. The primary endpoint was the duration of additional warning time provided by the ORi trigger. The secondary endpoint was the correlation of ORi and PaO2.

NCT ID: NCT04811963 Completed - Hypoxia Clinical Trials

SpO2 Accuracy Low Saturation Validation of the OxySoftN Sensor

Start date: April 6, 2021
Phase:
Study type: Observational

To compare prototype pulse oximeter saturation measurements, during normal to low saturation, to saturation measurements made by a multi-wavelength CO-oximeter, taken from arterial blood samples from healthy human subjects.

NCT ID: NCT04677894 Completed - Clinical trials for Airway Complication of Anesthesia

Comparison of Video Laryngoscopy and Direct Laryngoscopy for Nasotracheal Intubation During Pediatric Dental Surgery

Laryngoscopy
Start date: November 1, 2019
Phase:
Study type: Observational [Patient Registry]

Background and Objective: Airway control is a condition that should be evaluated primarily in anesthesia practice in the pediatric age group. Failed intubation or prolonged intubation duration can cause atelectasis and hypoxia in children. The aim of this study was to examine the effects of Macintosh laryngoscopy and McGrath videolaryngoscopy on hemodynamic parameters in pediatric patients who were scheduled to undergo elective dental surgery and required intubation for the application of general anesthesia. Methods: Sixty-six patients were divided into two groups according to the procedure used during intubation, namely, direct laryngoscopy or video laryngoscopy. The Cormack-Lehane and Mallampati scores, intubation duration, heart rate at minutes 0, 1, 3 and 5 during intubation, mean arterial pressure, EtCO2and SpO2 values were recorded for all the patients.
