简要总结
Gastric peristalsis, which occurs during the endoscopic procedure, limits the visual inspection of the inspection field, causing interference in the inspection. The actual endoscopic examination is most commonly used by injecting Hyoscine butylbromide(Buscopan®), Cimetropium bromide (Algiron ®) into intravenous or muscular injection so it is not suitable for patients who undergo non-sedative esophagogastroduodenoscopy. In addition, these drugs were reported the side effects including thirst, dysuria, transient visual filed defect, tachycardia, anxiety so were not recommended for benign prostate hyperplasia, glaucoma, old age patients. For comfort and succesfull test, anti-spasmodics which don't have anti-cholinergic effect and are possible to take orally is necessary. Phloroglucin(Flospan®) is a smooth muscle relaxant that is currently used in the anti-spasmodic treatment without anticholinergic action so it can be administered in patients with glaucoma or BPH. Also it is suitable for endoscopic premedication due to transparent liquid component. Therefore, in this study, we would like to confirm the efficacy and safety of Phloroglucin (Flospan ®), which can be taken orally, as an pre-medication for non-sedative endoscopy.
详细描述
Background : Endoscopy is currently widely regarded as the most important test in diagnosing stomach disorders, including stomach cancer. Gastric peristalsis, which occurs during the endoscopic procedure, limits the visual filed of the inspection, causing interference in the inspection. The actual endoscopic examination is most commonly used by injecting Hyoscine butylbromide(Buscopan®), Cimetropium bromide (Algiron ®) into intravenous or muscular injection so it is not suitable for patients who undergo non-sedative endoscopy because intravenous assessment is unnecessary. In addition, these drugs were reported the side effects including thirst, dysuria, transient visual filed defect, tachycardia, anxiety so were not recommended for patients with benign prostatic hyperplasia, glaucoma, old age. Actually patients who undergo non-sedative endoscopy are used to perform examinations without using anti-spasmodics. In this case, gastric peristalsis restricts endoscopist's visibility and making accurate observation and prolonged inspection time increases patient's discomfort. For comfort and successfull test, anti-spasmodics which don't have anti-cholinergic effect and are possible to take orally is necessary. Phloroglucin(Flospan®) prompts to release norepinephrine by impeding catecholamine O-methyl transferase enzymes in visceral smooth muscle, so it works to control spasm by normalizing smooth muscle movement which was accelerated by acetylcholine. Phloroglucin(Flospan®) is a smooth muscle relaxant that is currently used in the anti-spasmodic treatment without anticholinergic action so it can be administered in patients with glaucoma or BPH. Also it is suitable for endoscopic premedication due to transparent liquid component. Therefore, in this study, we would like to confirm the efficacy and safety of Phloroglucin (Flospan ®), which can be taken orally, as an pre-medication for non-sedative endoscopy.
Aim : Analysis for the effects of Phloroglucin (Flospan ®) as pre-medication for non-sedative endoscopy
Material and methods
This study is a single center, prospective, double blinded, randomized controlled trial that will be performed in Keimyung University Dongsan medical center. A total of 134 patients aged 18 to 80 are enrolled and patients were randomly assigned to the test group and the placebo group, taking the test drug or placebo 10 minutes before the endoscopy. The endoscopist records the degree of peristaltic movement and the degree of difficulty of the test at the start and end of the test. The degree of the peristalsis and the discomfort of the examination are evaluated by the scale used in the previous study. The questionnaire will be used to evaluate the patient's discomfort after drug administration, the taste of the drug, and the intention to re-use the drug.
