For colonoscopic FMT, the procedure will be performed with anesthesia support at the UNC Memorial Hospital endoscopy unit. Sedation will be at the discretion of the treating anesthesiologist in agreement with the endoscopist, but generally consists of intravenous propofol, with monitored anesthesia care. For colonoscopic FMT, the patient is given two 2mg doses of loperamide orally, two hours prior to FMT, and is then to take an additional two capsules after recovery from anesthesia (recommended immediately upon arrival home, when an outpatient procedure).
