RESUMO
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. Clinical and transfusion data of patients undergoing major elective surgery were collected; transfusion predictors and patients' outcomes were analysed. RESULTS: Of 6,121 patients, 1,579 (25.8%) received a peri-operative transfusion. A total of 5,812 blood components were transfused: red blood cells (RBC), fresh-frozen plasma and platelets in 1,425 (23.3%), 762 (12.4%) and 88 (1.4%) cases, respectively). Pre-operative anaemia was identified in 2,019 (33%) patients. Half of the RBC units were used by patients in the age group 45-69 years. Specific procedures with the highest RBC use were coronary artery bypass grafting (16.9% of all units) and hip arthroplasty (14.9%). Low haemoglobin concentration was the most common indication for intra-operative RBC transfusion (57%) and plasma and platelet transfusions were mostly initiated for acute bleeding (61.3% and 61.1%, respectively). The RBC transfusion rate in study centres varied from 2% to 72%. RBC transfusion was inappropriate in 99% (n=150/151) of pre-operative, 23% (n=211/926) of intra-operative and 43% (n=308/716) of post-operative RBC transfusion episodes. Pre-operative haemoglobin, increased blood loss, open surgery and duration of surgery were the main independent predictors of intra-operative RBC transfusion. Low pre-operative haemoglobin concentration was independently associated with post-operative pulmonary complications. CONCLUSIONS: These findings identified areas for improvement in peri-operative transfusion practice and PBM implementation in Turkey.

BACKGROUND AND OBJECTIVES: Sedative and analgesic treatment administered to critically ill patients need to be regularly assessed to ensure that previously stated goals are well achieved as the risk of complications of oversedation is minimized. We revised and prospectively tested the Ramsay Sedation Scale (RSS) for interrater reliability and compared it with the Riker Sedation-Agitation Scale (RSAS) and the Richmond Agitation Sedation Scale (RASS) to test construct validity during midazolam-remifentanil sedation. METHODS: A convenience sample of ICU patients was simultaneously and independently examined by pairs of trained evaluators by using the revised RSAS, RSS, and RASS. Ninety-two ICU patients were examined a total of 276 times by evaluator pairs. RESULTS: The mean patient age was 61.32±18.68years, 45,7% were female (n=42), 54.3% male (n=50). Their APACHE values varied between 3 and 39 with an average of 13.27±7.86 and 75% of the cases were under mechanical ventilation. When classified by using RSS (2.70±1.28), 10.9% were anxious or agitated (RSS1), 68.5% were calm (RSS 2-3), and 20.6% were sedated (RSS 4-6). When classified by using RASS (-0.64±1.58), 20.7% were anxious or agitated (RASS+1 to +4), 63.0% were calm (RASS 0 to -2), and 16.3% were sedated (RASS -3 to -5). When classified by using RSAS (2.63±1.00), 12% were anxious or agitated (RSAS 5-7), 57.6% were calm (RSAS 4), and 30.4% were sedated (RSAS 1-3). RSS was correlated with the RSAS (r=-0.656, p<0.001) and RASS was correlated with the RSAS (r=0.565, p<0.001). RSS was highly correlated with the RASS (r=-0.664, p<0.001). CONCLUSIONS: Ramsay is both reliable and valid (high correlation with the RASS and RSAS scales) in assessing agitation and sedation in adult ICU patients.
