Randomized Controlled Trial Comparative Study Clinical TrialA comparison of midazolam and diazepam for conscious sedation during colonoscopy in a prospective double-blind study.
Midazolam and diazepam are commonly used for conscious sedation, but their comparative respiratory depressive effects have not been accurately studied. We used a novel real-time, on-line, computerized data acquisition system to compare the two agents in a randomized double-blind study. ⋯ Midazolam was 3.4 times more potent than diazepam. The duration of oxygen desaturation emphasizes the importance of monitoring SpO2 until ventilation and oxygenation have recovered. Although the degree of hypoxemia was comparable, midazolam led to higher end-tidal carbon dioxide tensions.

Randomized Controlled Trial Comparative Study Clinical TrialEfficacy and safety of intravenous propofol sedation during routine ERCP: a prospective, controlled study.
Adequate patient sedation is mandatory for diagnostic and therapeutic endoscopic retrograde cholangiopancreatography (ERCP). The short-acting anesthetic propofol offers certain potential advantages for endoscopic procedures, but controlled studies proving its superiority over benzodiazepines for ERCP are lacking. ⋯ Intravenous sedation with propofol for ERCP is (1) more effective than sedation with midazolam, (2) safe under adequate patient monitoring, and (3) associated with a faster postprocedure recovery.

Randomized Controlled Trial Clinical TrialImpact of flumazenil on recovery after outpatient endoscopy: a placebo-controlled trial.
Flumazenil is an imidazobenzodiazepine that blocks the central effects of benzodiazepines by competitive interaction at the receptor level. In this study we assessed the impact of flumazenil use on postsedation observation time in outpatients undergoing endoscopy. ⋯ Flumazenil significantly reduces postsedation observation time. Actual cost savings will vary depending on staff and facility capacity, patient volume, flumazenil cost, and unit cost of observation time.

Randomized Controlled Trial Clinical TrialPlacebo-controlled trial assessing the use of oral midazolam as a premedication to conscious sedation for pediatric endoscopy.
This study was performed to evaluate the effect of midazolam, as premedication before intravenous conscious sedation, on preprocedural, procedural, and post-procedural patient comfort and anxiety in children undergoing endoscopy. ⋯ Oral midazolam is an effective and safe premedication for children undergoing upper endoscopy and should be used in all anxious children and in patients previously judged to be difficult to sedate.

Randomized Controlled Trial Comparative Study Clinical TrialA prospective randomized trial comparing the use of the flexible gastroscope versus the bronchoscope in the management of foreign body ingestion.
Foreign body ingestion is a common clinical problem in Hong Kong. Some recent reports have proposed the use of flexible nasoendoscopy for foreign body retrieval. The present study is a prospective randomized trial on the use of the flexible gastroscope and bronchoscope in the management of foreign body ingestion. ⋯ The use of the flexible gastroscope is recommended because of its efficacy, safety, and tolerability.
