BACKGROUND To eliminate the risk of combustion during electrosurgical procedures and to reduce patient discomfort, carbon dioxide (CO2) insufflation has been recommended during colonoscopy. However, air insufflation is still the standard method, perhaps due to the lack of suitable equipment and shortage of randomised studies. AIMS This randomised controlled trial was conducted to assess patie...

Commercial equipment is available for conducting Eustachian tube function tests but, generally, the Eustachian tube insufflation method doubles as a treatment and diagnosis. However, with the Eustachian tube insufflation method, the doctor merely performs the auscultation. The Eustachian tube insufflation sounds are not saved as data, and the diagnosis relies on the auditory judgment of the doc...

INTRODUCTION The respiratory effects (changes in pH and PaCO(2)) of carbon dioxide insufflation in thoracoscopic surgery in adult patients with pulmonary disease were not documented previously. METHODS In this observational study 21 patients scheduled for elective thoracoscopic surgery with one lung ventilation using a double lumen tube and intraoperative carbon dioxide insufflation were stud...

Carbon dioxide embolism is a rare but potentially devastating complication of laparoscopy. To determine the effects of insufflation pressure on the mortality from carbon dioxide embolism, six swine had intravascular insufflation with carbon dioxide for 30 seconds using a Karl Storz insufflator at a flow rate of 35 mL/kg/min. The initial insufflation pressure was 15 mm Hg. Following recovery fro...

Objective. Despite the advantages of laparoscopic cholecystectomy (LC), postoperative pain remains a major complaint for many patients. In this study, in patients undergoing LC, the application of LC via incisional bupivacaine and low inflation pressure, alone or combined, and a comparison of the effects on postoperative pain has been purposed. Methods. Patients were randomly assigned into the ...

Over the past 50 years, a variety of techniques have been developed that have in common the insufflation of gas into the central airway to facilitate carbon dioxide (CO2) clearance. These include continuous insufflation of oxygen, transtracheal jet ventilation, high frequency jet ventilation, transtracheal oxygen administration, intratracheal pulmonary ventilation, and tracheal gas insufflation...

During colonoscopy, air insufflation to distend the lumen and facilitate careful inspection and scope insertion can induce pain and cause discomfort. Carbon dioxide (CO2) insufflation can decrease abdominal pain and discomfort during and after colonoscopy. The advantage of CO2 insufflation is the rapid absorption of the gas across the intestine. Another painless option is water-assisted colonos...
