Randomized Controlled Trial Clinical TrialA cost and performance evaluation of disposable and reusable biopsy forceps in GI endoscopy.
Biopsy forceps are widely used in gastrointestinal endoscopy, and yet few data exist on the usage and costs associated with disposable versus reusable forceps. ⋯ Up to 15 to 20 uses, disposable and reusable forceps costs were similar. If reusable forceps are used more than 20 times, then they are less expensive. However, in this range of uses, reusable biopsy forceps performance diminishes. With disposable biopsy forceps costing less than $40, cost differences between reusable and disposable forceps are minimal.

Randomized Controlled Trial Multicenter Study Clinical TrialA randomized, controlled trial of transcutaneous carbon dioxide monitoring during ERCP.
Pulse oximetry, used to monitor oxygen saturation during endoscopy, does not directly measure hypoventilation. Study goals were to determine whether transcutaneous carbon dioxide (PtcCO(2)) monitoring during endoscopic retrograde cholangiopancreatography (ERCP) prevents severe hypoventilation and to assess the accuracy of clinical observation and pulse oximetry in detecting hypoventilation. ⋯ Carbon dioxide retention during ERCP is not reliably detected by clinical observation or by pulse oximetry in patients receiving supplemental oxygen. The addition of PtcCO(2) monitoring prevents severe carbon dioxide retention more effectively than intensive clinical monitoring and pulse oximetry alone. The clinical relevancy of this observation needs to be determined in an appropriately designed outcome study.

Randomized Controlled Trial Clinical TrialDisposable versus reusable biopsy forceps: a prospective cost evaluation.
There is growing advocacy for the use of disposable medical accessories to reduce the risks of infection transmission. Their purchase costs can, however, be considered as prohibitive in an endoscopy unit operating under a cost-containment program. We therefore compared the costs of reusable and disposable biopsy forceps. ⋯ Total purchase and reprocessing costs for reusable biopsy forceps were 25% of those of disposable devices. The use of disposable biopsy forceps would have led to a yearly extra cost of $78,377 in the operation of our endoscopy unit.

Randomized Controlled Trial Clinical TrialNitrous oxide for colonoscopy: a randomized controlled study.
Intravenous sedation/analgesia for colonoscopy is accompanied with certain risks and postprocedure drowsiness. We sought to determine whether inhaled nitrous oxide (Entonox: 50% nitrous oxide, 50% oxygen) provides adequate analgesia for colonoscopy and the impact of this agent on recovery. ⋯ Entonox is less effective than midazolam with meperidine for colonoscopy but is acceptable in many patients and allows faster recovery.
