Peri-operative blood transfusion in elective major surgery: incidence, indications and outcome - an observational multicentre study.

Background: Patients' demographic and epidemiological characteristics, local variations in clinicians' knowledge and experience and types of surgery can influence peri-operative transfusion practices. Sharing data on transfusion practices and recipients may improve patients' care and implementation of Patient Blood Management (PBM).

Materials And Methods: This was a multicentre, prospective, observational, cross-sectional study that included 61 centres.

Abuse potential assessment of propofol by its subjective effects after sedation.

Objective: In this study, we examined the euphoric effect of propofol and its high satisfaction ratio regarding its liability to be abused, particularly in painless procedures, such as colonoscopy.

Methods: Fifty subjects aged between 18 and 65 years who fulfilled the criteria for ASA 1-2 and were prepared for colonoscopy were enrolled into this study. For intravenous sedation induction, 2 mg/kg propofol was used, and additional injections were administered according to BIS values.
