The delivery of inhaled anesthetics with high FGF prior to securing the airway remains common practice. We fail to consistently adjust MAC to age and poorly titrate opioids to reduce the fraction of the MAC we administer. We fail to incorporate hysteresis which is reflected in the use of excessively high FGF and vaporizer settings during wash-in and in the failure to maintain low FGF prior to emergence (“coasting”). By failing to fully appreciate the quantitative effects of the delivery if inhaled anesthetics we miss the opportunity to reduce waste to the absolute minimum. Belief and myth are strong when the environmental impact of inhaled anesthetics is considered. We need better, detailed life cycle analyses with low flow data before making claims pro/con inhaled/TIVA.

It frequently presents as a result of a disease or an injury. Obesity and obesity-related comorbidities are a major health problem and are dramatically increasing year after year. Dieting and physical exercise show disappointing results in the treatment of obesity. Therefore, bariatric surgery is increasingly widely offered as a weight reducing strategy. In our pain clinic we see a lot of patients who suffer from chronic abdominal pain after bariatric surgery. This review aims to explore the link between chronic abdominal pain and bariatric surgery in this specific type of patients.\u0000\u0000Method: The review is based on searches in PubMed, Embase and Cochrane databases. Keywords are used in different combinations. We did a cross-reference of the articles included.\u0000\u0000Results: Chronic abdominal pain after bariatric surgery is very common. Around 30% of the bariatric patients experience persistent abdominal pain. An explanation for the abdominal pain is found in 2/3 of these patients.\u0000There is a wide variety of causes including behavioral and nutritional disorders, functional motility disorders, biliary disorders, marginal ulceration and internal hernia. Another, frequently overlooked, cause is abdominal wall pain. Unexplained abdominal pain after bariatric surgery is present in 1/3 of the patients with persistent abdominal pain. More studies are needed on the risk factors and prevention of unexplained abdominal pain in bariatric patients.","PeriodicalId":7024,"journal":{"name":"Acta anaesthesiologica Belgica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43754341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our institutional strategy is based on a systematic type and screen (T/S) ordering of 3 PRBCs at the blood bank then stored in a dedicated refrigerator in the operating room for each patient scheduled for cardiac surgery. However, these PRBC units are not always transfused and are therefore at risk of destruction if temperature fluctuations are detected during transport and storage processes. In addition, these orders represent a burden for the blood bank. Therefore, it is relevant to move towards a more tailored PRBC order before cardiac surgery and challenge the systematic ordering protocol.\u0000\u0000Methods: The Transfusion Understanding Scoring Tool (TRUST) and the Transfusion Risk and Clinical Knowledge (TRACK) Score are designed to stratify blood transfusion needs in cardiac surgery. We retrospectively performed both scores for each patient scheduled for cardiac surgery. Then, we compared their performance to predict PRBC transfusion and determined the optimal threshold to optimize the preoperative PRBC order reflecting the needs of our population managed with our local standards.\u0000\u0000Results: Receiver operating characteristic (ROC) curves for prediction of PRBC transfusion using the two scores were computed for the whole cohort (n=1249). Both scores performed well (areas under ROC curves: 0.81 and 0.82 (95% CI) using the TRACK Score and the TRUST, respectively). A TRUST < 3 identified a subgroup of patients (53.6%) at low risk of transfusion. The availability of 1 T/S PRBC in the OR would cover the needs of the majority (92.5%) of this group.\u0000\u0000Conclusions: In our institution, the use of the TRUST preoperatively could offer a more tailored T/S PRBC order for the intraoperative period, especially in the low-risk transfusion group.","PeriodicalId":7024,"journal":{"name":"Acta anaesthesiologica Belgica","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70729994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
