Measuring hemoglobin level by spectrophotometry (SpHb) plays an important role in making this decision. The accuracy of SpHb depends on the finger perfusion. Since digital nerve blocks (DNB) can enhance blood circulation, we aimed at investigating DNB effects on the accuracy of SpHb.\u0000\u0000Methods: Patients undergoing spine surgery were randomly assigned to two groups. Group A received DNB in the left hand, and group B received DNB in the right hand. In each group, the other hand was considered as the control. Rainbow adult ReSposable sensors were attached to the patients’ both hands. Before surgical incision and every 1.5 hours, the SpHb values of both hands and the perfusion index were recorded. Concomitantly, arterial blood samples were drawn and sent to the lab for hemoglobin concentration measurement. This served as the gold standard for assessing hemoglobin levels (labHb). We used a mixed-effects generalized linear model to test the effect of independent variables on the difference between SpHb and labHb at each time point.\u0000\u0000Results: The SpHb displayed higher hemoglobin levels than those assessed by the lab. For lower labHb values, the SpHb-labHb differences were larger. A one-unit decrease in labHb increased the difference between SpHb and labHb by 0.56 g dL -1 , which was statistically significant.\u0000DNB significantly increased the difference between SpHb and labHb by 0.42 g dL -1 . The effect of DNB on the difference between SpHb and labHb was significant up to three hours after the beginning of surgery (0.58 g dL -1 difference between blocked and non-blocked hands).\u0000\u0000Conclusion: This study shows that, when hemoglobin levels are low, the accuracy of spectrophotometry decreases. Although DNB increases finger perfusion, it leads to an overestimation of hemoglobin levels by SpHb.","PeriodicalId":7024,"journal":{"name":"Acta anaesthesiologica Belgica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48552306","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 first procedure was prematurely interrupted after the return of spontaneous circulation (ROSC) while the other was continued under intravenous (IV) perfusion of nitrates (isosorbide dinitrate). At each time, after a cycle of cardiopulmonary resuscitation (CPR) and injection of atropine 0.5 mg, sinus rhythm was restored. Only 3-lead electrocardiogram (ECG) outlines were recorded, showing ST-elevation in lead II. During the first incident, a coronary angiography was performed showing a vasospasm of the left anterior descending (LAD) coronary artery, reversible upon intracoronary injection of nitrates. ECG during catheterization showed ST-elevation in the anterior coronary territory. Calcium-channel blockers (CCB) were prescribed, and oral nitrates were added after the second episode. Cardiovascular prevention consisted in smoking cessation, aspirin and statins. Reporting this case seems to be relevant due to its unusual presentation: Prinzmetal’s angina is usually described as morning chest pains, and it rarely concerns Caucasian men. Moreover, the vasospasm was associated with cardiac arrest and ECG changes suggestive of ST-elevation myocardial infarction (STEMI). The final diagnosis was myocardial infarction with non-obstructive coronary arteries (MINOCA) due to coronary vasospasm, a few minutes after insufflation of pneumoperitoneum. So far, few cases have been described during non-cardiac surgery, and even fewer during laparoscopy. Sharing our experience seems important to attract attention to cardiovascular events that can occur under general anesthesia, especially when clinical presentation is rare.","PeriodicalId":7024,"journal":{"name":"Acta anaesthesiologica Belgica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42964891","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 sudden onset of severe abdominal distension and the presence of air in the intra-abdominal drain suggested tension pneumoperitoneum, confirmed by radiography. No pneumothorax was associated. Urgent decompression was required to improve hemodynamics. Perforation of the gastrointestinal tract was ruled out. The cause was a bronchopleural fistula opened by mechanical ventilation. Rarely, cardiorespiratory failure may occur after tension pneumoperitoneum by reducing lung volume and cardiac preload, similar to obstructive shock from the usual intrathoracic causes or acting as an abdominal compartment syndrome (ACS). Its recognition and abdominal decompression are key steps in the patient’s recovery.

How- ever, given the conflicting evidence on this topic, we studied the effects of methylprednisolone on critically ill patients and - share here our experience on laboratory findings and the Pa02/FiO2 ratio (ratio of partial oxygen concentration on arterial blood gas sample to fraction of inspired oxygen).\u0000\u0000Methods : In a population of 68 patients hospitalized in the intensive care unit due because of COVID-19 infection, 28 patients with severe respiratory failure received methylprednisolone on a fixed 12-day regimen (125 mg IV for 2 days, followed by 2x0.5 mg/kg IV twice daily for 5 days, and then a decreasing regimen for 4 days until discontinuation). After day 5 and day 10, we analyzed the levels of CRP (C-reactive protein), lymphocytosis, D-dimer, LDH (lactate dehydrogenase) and PaO 2 /FiO 2 ratio of our patients.\u0000\u0000Results : We observed a significant decrease in median CRP levels between day 0 (start of methylprednisolone treatment) and day 5 (p=0.001), and between day 0 and day 10 (p=0.005). No decrease was seen between day 5 and 10 (p=0.352). The same increase in PaO 2 /FiO 2 was recorded between day 0 and day 5 (p=0.009), and between 0 and day 10 (p=0.019). For D-dimer, only a significant difference was found between day 0 and day 10 (p=0.018). No significant difference could be observed for lymphocytosis and LDH levels between the beginning of the treatment and day 5 or day 10.\u0000\u0000Conclusion : There is a strong and sustained significant decrease in CRP levels and a tilt in the PaO2/FiO2 ratio after starting methylprednisolone. A slower, but also significant decrease was found for D-dimer. Further research and control group analyses are needed to confirm that this effect is due to corticostreoid treatment. However, this indicates that methylprednisolone may play a very important role in the treatment of the severely ill COVID-19 patients requiring ICU admission.","PeriodicalId":7024,"journal":{"name":"Acta anaesthesiologica Belgica","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41317277","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}

Post- cesarean pain is often underestimated and undertreated and can impair rapid maternal recovery, mother and child bonding and breastfeeding. Recently, PROSPECT recommendations on postoperative pain for CS were published and they include systematic paracetamol and non-steroidal anti-inflammatory drugs (NSAIDs), intravenous dexamethasone, neuraxial morphine/dia- morphine or an abdominal wall block or wound infiltration, abdominal wall binders, non-closure of the peritoneum and a Joel-Cohen incision. Opioids are administered as rescue. In UZ Leuven, these PROSPECT recommendations were implemented at the end of 2020. To evaluate the efficacy of these PROSPECT recommendations, a prospective audit was performed from January 1 st , 2021 till April 30 th , 2021. All patients with a CS were prospectively followed for correct implementation of the pain protocol and for pain scores in rest and at mobilization. Rescue opioid consumption as well as patient satisfaction were recorded. 185 consecutive patients that had undergone a CS were included in the audit. In 55 patients the pain protocol was not followed mostly due to no or reduced administration of NSAIDs. Patient satisfaction was high, especially in patients in which the protocol was followed. Pain scores at rest and at mobilization were low and the percentage of patients having pain scores above 30 mm VAS remained low. Rescue opioid consumption was low. We conclude that the implementation of the PROSPECT based pain protocol after CS was effective in controlling pain, reducing opioid consumption and resulted in high patient satisfaction especially if the protocol was correctly followed. Omission of NSAIDs is occurring relatively frequent, but mostly because of valid medical reasons to omit NSAIDs.","PeriodicalId":7024,"journal":{"name":"Acta anaesthesiologica Belgica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42860420","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}
