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":null,"pages":null},"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":null,"pages":null},"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}

The recognition of CPSP as a disease and the release of a common definition of the condition is an important progress in the field. CPSP predictive scores exist but none has presently demonstrated an impact on patient care.

Near-infrared spectroscopy (NIRS) can be applied paravertebrally to monitor the oxygenation of the collateral network, which contributes to the spinal cord blood supply. It has already been demonstrated that regional cerebral oxygen saturation (rScO2) increases following sympathetic stimulation.\u0000\u0000Objectives: We hypothesized that laryngoscopy would cause an increase in cerebral and paraspinal regional tissue saturations (rScO2 and rSpsO2, respectively).\u0000\u0000Design: Retrospective analysis of a previous conducted randomized trial.\u0000\u0000Setting: Laryngoscopy in the operating room.\u0000\u0000Methods: Data of 28 patients, scheduled for arterial dilation of the lower limb, were retrospectively analyzed.

A balanced isotonic solution with 1-2,5% glucose should be used as perioperative maintenance IV fluid in children (1 month to 18 years). Colloids can be used in children when inadequate effect in volume correction is achieved with crystalloids. The preferred synthetic colloid for children is a third generation HES in a balanced solution. To date, most clinicians use the “4-2-1 rule” for calculating fluid rate. This may not be the optimal fluid rate, as little research has been done.

They may counteract the adverse effects of stress on the non-technical skills of the attending clinician(s). Although most clinicians acknowledge the importance of CAs, their uptake in clinical practice seems to be lagging behind. This situation has led us to investigate which features of CAs may enhance their uptake. Therefore, in this systematic review we explored the optimums regarding the 1) timing to consult the CA, 2) person consulting the CA, 3) location of the CA in the operating room, 4) CA design (paper vs. electronic), 5) CA lay-out, 6) reader of the CA and 7) if the use of CAs in the form of decision support tools lead to improved outcome.\u0000\u0000Methods: Seven PICO-questions guided our literature search in 4 biomedical databases (MEDLINE, Embase, Web of Science and Google Scholar). We selected English-language randomized controlled trials (RCTs), observational studies and expert opinions discussing the use of cognitive aids during life-threatening events in the operating theatre. Articles discussing non-urgent or non-operating room settings were excluded. The quality of evidence was evaluated with the Grading of Recommendations Assessment, Development and Evaluation (GRADE).\u0000\u0000Results: We found 7 RCTs, 14 observational studies and 6 expert opinions. All trials were conducted in a simulation environment. The person who should trigger the use of a cognitive aid and the optimal timing of its initiation, could not be defined by the current literature. The ideal location of the cognitive aids remains also unclear.\u0000\u0000A favorable lay-out of an aid should be well-structured, standardized and easily readable.

Likewise, the presence of a reader was associated with an improved performance of key steps in the management of a critical event. However, it remains unclear who should fulfill this role.\u0000\u0000Conclusion: Several features of the design or utilization of CAs may play a role in enhancing the uptake of CAs in clinical practice during the management of a critical event in the operating room.
