Carbon Dioxide Versus Air Insufflation for the Application of Argon Plasma to Reduce the Gastrojejunal Anastomosis

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.

Cholangiography Using Carbon Dioxide Versus Iodinated Contrast in ERCP

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 ...

Efficacy and Safety of Carbon Dioxide Insufflation During Endoscopy

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.

Safety and Efficacy of CO2 for 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 ...

Efficacy of Different Densities of Fractional Carbon Dioxide in Treatment of Post Burn Scars

This study aims to compare effectiveness of different densities of carbon dioxide fractional laser in the treatment of postburn scar.

Nasal Carbon Dioxide for the Symptomatic Treatment of Classical Trigeminal Neuralgia

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.

Comparison Air Versus Carbon Dioxide Insufflation in Single Balloon Anterograde Enteroscopy

Observation study comparing patient symptoms of bloating, pain, and nausea between CO2 insufflation vs. O2 insufflation in anterograde balloon enteroscopy.

The Effect of Nasal Carbon Dioxide (CO2) on Nasal Congestion in Subjects With Perennial Allergic Rhinitis

The purpose of this study is to evaluate the effect of nasal CO2 on nasal congestion and other symptoms related to Perennial Allergic Rhinitis.

Ability of Changes in End Tidal Carbon Dioxide to Assess the Stroke Volume Effects of a Volume Expansion of 250ml of Crystalloid in the Operating Room

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...

Study of the Carbon Dioxide Treatment for Fat Reduction

The primary objective of this study is to demonstrate the efficacy and safety of the carbon dioxide for subcutaneous fat reduction.

Burn Scar Appearance After Treatment With Fractional Carbon Dioxide (CO2) Laser

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.

Endtidal Carbon Dioxide for Earlier Detection of Pulmonary Hypertension

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.

A Study to Determine if Carbon Dioxide Lavage During Total Knee Surgery Reduces Intraoperative Embolic Events

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.

Serrated Polyp Detection Rate Between Carbon Dioxide and Air Insufflation

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...

Subcutaneous Carbon Dioxide Insufflations for Acute Non Specific Neck Pain

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.

Comparison of Carbon Dioxide (CO2) to Air Insufflation in Colonoscopy in Patients With Inflammatory Bowel Disease

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...
