We list hundreds of Clinical Trials about "Carbon Dioxide" on BioPortfolio. We draw our references from global clinical trials data listed on ClinicalTrials.gov and refresh our database daily.
We have published hundreds of Carbon Dioxide news stories on BioPortfolio along with dozens of Carbon Dioxide Clinical Trials and PubMed Articles about Carbon Dioxide for you to read. In addition to the medical data, news and clinical trials, BioPortfolio also has a large collection of Carbon Dioxide Companies in our database. You can also find out about relevant Carbon Dioxide Drugs and Medications on this site too.
We aim to test our method for measuring chemosensitivity (the ventilatory response to a change in carbon dioxide), which uses sinusoidal carbon dioxide stimuli. Hypotheses: - Carbon dioxide sensitivity is dependent on the cycle time over which we administer the gas (frequency). - Chemoreflex gain decreases as deadspace increases.
Carbon dioxide insufflation during colonoscopy significantly reduces discomfort (pain, bloating and flatulence) after the procedure. So far, it has not been studied in inflammatory bowel disease patients. The study was designed to evaluate discomfort after the carbon dioxide insufflation colonoscopy in comparison to standard air insufflation colonoscopy.
The purpose of this study is to determine if blowing carbon dioxide into the surgical field during open-heart surgery to displace retained chest cavity air from the atmosphere will decrease the number of microembolic being introduced into the heart chambers and brain.
Endovascular repair of infrarenal abdominal aortic aneurysms (AAA) requires a contrast agent to identify the vascular anatomy and placement of the stent graft. Iodine contrast has traditionally been used, but has the potential to harm the kidneys. Another contrast agent is carbon dioxide gas. It has been proven safe to use, but the quality of the images it creates needs to be compared to iodine contrast. Patients in this study undergo the endovascular AAA repair as they nor...
Investigators evaluate the effect of patient position (Trendelenburg and reverse Trendelenburg) on arterial, end-tidal and transcutaneous carbon dioxide partial pressure in patients undergoing laparoscopic surgery.
To analyze a multi-center observational study database. to select adult non-traumatic in-hospital cardiac arrest. Review and recored end-tidal carbon dioxide in per minute. Arrange them in different time line. one is in resuscitation time. The other is the time line which the beginning time is the time of starting appearing stable end-tidal carbon dioxide wave.To compare predictive power of end-tidal carbon dioxide between different time line during resuscitation.
The objective of this randomized clinical trial is to compare pain levels during and after insufflation with carbon dioxide or in subjects that will undergo endoscopic fulguration with argon to reduce the diameter of the gastrojejunal anastomosis. The investigators hypothesize that carbon dioxide will be superior in causing less pain and leading to less discomfort.
Carbon dioxide (CO2) gas is widely used for luminal insufflation during endoscopic retrograde cholangiopancreatography (ERCP) of the biliary tract. While frequently observed during routine ERCP, there are few data on the topic of "air" or "CO2" cholangiography. Our primary aim is to compare radiographic cholangiograms in patients with biliary tract disease (from stones or strictures) during ERCP obtained by using carbon dioxide as the contrast medium vs. conventional iodinated ...
The purpose of this study is to assess the differences of safety and efficacy of carbon dioxide insufflation instead of air during sedated or unsedated endoscopy.
Hypothesis: Carbon dioxide gas use for endoscopic insufflation is safe and results in less abdominal distension and discomfort; it is equally effective as air in pediatric patients undergoing endoscopic procedures. Aim 1: Determine the occurrence and severity of abdominal discomfort and distension associated with endoscopic procedures at baseline, upon awakening from anesthesia, at discharge and at 4 hours after discharge in carbon dioxide group when compared to ...
This study aims to compare effectiveness of different densities of carbon dioxide fractional laser in the treatment of postburn scar.
A placebo-controlled, single-blind study to evaluate the safety and preliminary efficacy of nasal carbon dioxide for the symptomatic treatment of classical trigeminal neuralgia.
Observation study comparing patient symptoms of bloating, pain, and nausea between CO2 insufflation vs. O2 insufflation in anterograde balloon enteroscopy.
The purpose of this study is to evaluate the effect of nasal CO2 on nasal congestion and other symptoms related to Perennial Allergic Rhinitis.
Volume expansion is the cornerstone of perioperative hemodynamic optimization. The main objective of volume expansion is to increase and to maximize stroke volume. Despite national and international recommendations, stroke volume monitoring is clearly not widely adopted. This is mostly due to the cost and the invasiveness of the devices allowing stroke volume monitoring. End tidal carbon dioxide is monitored in all patients undergoing general anaesthesia and is totally non-inva...
The primary objective of this study is to demonstrate the efficacy and safety of the carbon dioxide for subcutaneous fat reduction.
The purpose of this study is to determine if fractional carbon dioxide laser treatment of a burn scar is a more effective method for improving the appearance of scars than the current available treatments.
Measurement of the endtidal carbon dioxide by capnography to exclude or to ensure the diagnosis pulmonary hypertension. The aim of the study is to obtain an endtidal carbon dioxide cut-off value for the diagnostic algorithm for pulmonary hypertension as an easily measurable and cheap diagnostic tool in patients with suspicion of pulmonary hypertension.
The purpose of this study is to determine if the use of a carbon dioxide lavage device (CarboJet) to clean bone surfaces during total knee surgery decreases intraoperative embolic events when compared with standard orthopedic techniques.
Sessile serrated adenomas are characterized by their flat shape and the presence of a yellow mucus cap overlying the lesion. These morphological features may account for their diagnostic difficulty during colonoscopy. Missed proximal sessile serrated adenomas are regarded as an important cause for interval cancers in the right colon and emphasize the importance of developing quality measures intended to enhance their detection. There is only one single-center retrospective coho...
The purpose of the trial is to evaluate whether patients with acute non specific neck pain get pain free sooner, if treated with subcutaneous carbon dioxide insufflations compared to sham ultrasound.
Patients with inflammatory bowel disease (IBD) frequently undergo endoscopic examination and may suffer from diagnostic procedures. Independent from IBD patients, colonoscopy is usually performed using air insufflation, however recent data indicates a superior role of carbon dioxide (CO2) as an insufflation gas during colonoscopy. Using CO2 leads to a lower degree of patient's discomfort. The role of CO2 as an insufflation gas for colonoscopy in IBD patients remains undetermine...
Observational study to analyze correlation between partial pressure of carbon dioxide from blood obtained from peripheral and central veins
The purpose of this study is to study the effects of carbon dioxide combined with head down tilt on cerebral physiology and anatomy. This paradigm will help establish a ground-based analog for spaceflight, and also evaluate the ability of non-invasive devices to monitor brain physiology.
The purpose of this study is to better understand the way in which CO2 (carbon dioxide) affects the symptoms of allergic rhinitis or hayfever. Our intent is to determine if CO2 has an effect on nasal challenge with antigen as a predictor of whether it will have a beneficial effect on the treatment of seasonal allergic rhinitis.
