Randomized Controlled Trial
Efficacy of bispectral index monitoring during balanced propofol sedation for colonoscopy: a prospective, randomized controlled trial.
Appropriate use of propofol is necessary, and objective monitoring of sedation with propofol may be helpful. Studies on the efficacy of bispectral index (BIS) monitoring in deep sedation have been conducted, but its efficacy in colonoscopy with moderate sedation is unknown. In this study, the efficacy of BIS monitoring during colonoscopy with moderate level sedation via balanced propofol sedation was investigated. ⋯ BIS and clinical sedation scores, MOAA/S scores, showed a high level of correlation. However, no significant efficacy was observed in the BIS group who underwent outpatient colonoscopy.

Previous epidemiological studies on Clostridium-difficile-Associated Diarrhea (CDAD) have focused on hospitalized patients with nosocomial transmission. However, increasing numbers of patients with CDAD are being admitted to acute-care hospitals from long-term care facilities (LTCFs) and the local community. The purpose of our study was to study the changing epidemiological trends of CDAD patients admitted to an acute-care hospital and examine factors contributing to this shift in epidemiology. ⋯ These observations suggest that CDAD originated predominantly in patients from LTCFs (46.1%) and community (33.3%) rather than from hospitalized patients (20.6%). Diarrhea was the presenting complaint in LTCF patients in only 15.2% of cases. Hence, CDAD should be suspected if LTCF patients present with symptoms such as abdominal pain, fever, or altered mental status along with loose stools. Majority of the LTCF patients were found to be on PPIs, a risk factor for CDAD, with as many as 24% of these patients with no valid indication for their use.
