The incidence of emergence delirium in children varies mainly according to the anesthetic agents used.\u0000\u0000Methods: In this prospective, double-blind, randomized trial, 152 children of age group 1-6 years were randomized into two groups after induction of anesthesia: Group S received Sevoflurane, and Group D received Desflurane. Children in the S group were further randomized into subgroup S- Dex (receiving dexmedetomidine 0.3 mcg/kg in 5 ml saline) and subgroup S-Saline (receiving saline 5 ml). Similarly, Group D was also randomized into two subgroups; D-Dex and D-Saline. We compared perioperative hemodynamic variables, postoperative emergence delirium, recovery profile, pain scoring, the requirement of rescue analgesics, and time to discharge.\u0000\u0000Results: At 5, 15, and 30 minutes, the incidence of emergence delirium was significantly higher in S-Saline and D-Saline groups than S-Dex and D-Dex groups. Both PAED and FLACC scores were significantly higher in the S-Saline group than the S-Dex group and the D-Saline group compared to the D-Dex group (P<0.05). Significantly more patients required analgesia in the S-Saline group than in the S-Dex group (P<0.05). No significant difference for analgesia was present between D-Saline and D-Dex groups. (p = 0.153). Discharge time was significantly longer in S-Dex and D-Dex groups as compared to S-Saline and D-saline groups.\u0000\u0000Conclusions: Dexmedetomidine effectively reduced the incidence of emergence delirium and postoperative pain in pediatric patients undergoing surgery using Sevoflurane and Desflurane anesthesia.","PeriodicalId":7024,"journal":{"name":"Acta anaesthesiologica Belgica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43162492","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}

Vandenheuvel","doi":"10.56126/73.1.03","DOIUrl":"https://doi.org/10.56126/73.1.03","url":null,"abstract":"High frequency percussive ventilation (HFPV) is a ventilation mode that combines positive pressure ventilation with some advantages of high frequency ventilation. During HFPV, a pulsatile flow is generated with high frequency and low volumes. HFPV has been used in the intensive care unit (ICU) for several decades, in case of insufficient conventional positive pressure ventilation. However, literature on its use in intraoperative care is scarce. We hypothesize that HFPV might be a better alternative to existing ventilation modi during selected operative procedures or in patients with severely compromised pulmonary and/or cardiac function. In this paper, we explain the HFPV system, we zoom in on the physiological effects of HFPV, and we describe its potential role in the intraoperative setting. Results of existing studies show that, compared to other conventional ventilation modes, HFPV improves oxygenation and ventilation without jeopardizing hemodynamics. However, because of the low quality evidence regarding physiological effects and clinical effectiveness, and due to the complicated design and set-up of the HFPV ventilator, the use of HFPV in intraoperative care is currently very limited. We conclude that HFPV could potentially be an interesting ventilation mode for procedures requiring minimal respiratory motion or low airway pressures, however larger (comparative) study trials are required to evaluate its usability in the operating room in patients with compromised pulmonary and/or cardiac function.","PeriodicalId":7024,"journal":{"name":"Acta anaesthesiologica Belgica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45072836","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 pathophysiology of the lung failure in COVID- 19 ARDS is a combination of the viral infection and the immune response of the host. ARDS due to COVID-19 appears to be similar to the non-COVID-19 ARDS, with exception of hypercoagulability. The mortality due to ARDS remains high and the treatment focuses on supportive measures, such as lung-protective ventilation strategy with small tidal volumes, low driving pressures and PEEP-titration, early consideration of prone positioning and a restrictive fluid management. Oxygen should be titrated, and permissive hypercapnia might be necessary to achieve lung-protective ventilation. The use of extracorporeal membrane oxygenation (ECMO) in COVID-19 ARDS is restricted as a rescue therapy in patients who remain hypoxemic. ECMO should be reserved to experienced ECMO centers. Prophylactic anticoagulant therapy is indicated to reduce the formation of thrombi in the microcirculation of organs, especially in the pulmonary microvasculature. Steroids may reduce the host’s immune response and improve mortality in patients requiring oxygen supplementation or invasive ventilation.","PeriodicalId":7024,"journal":{"name":"Acta anaesthesiologica Belgica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41246165","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}

We focused on the detection of elevated ICP after TBI and discussed the possible improvements in detection methods.\u0000\u0000Conclusions : US measurement of ONSD in TBI cases provides a qualitative but no quantitative assessment of ICP. Current studies usually calculate their own optimum cutoff value for detecting raised ICP based on the balance between sensitivity and specificity of the method when compared with invasive methods. There is no universally accepted threshold. We did not find any paper focusing on the prognosis of patients benefiting from it when compared with usual care. Another limitation is the lack of standardization. US measurement of ONSD cannot be used as the sole technique to detect elevated ICP and monitor its evolution, but it can be a useful tool in a multimodal protocol and it might help to determine the prognosis of patients in various situations.","PeriodicalId":7024,"journal":{"name":"Acta anaesthesiologica Belgica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45631952","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}

In this case report, venoarterial extracorporeal membrane oxygenation (VA-ECMO) was used for hemodynamic stabilization and was continued during the resection of a large neuroendocrine tumor.\u0000\u0000Description : A 69-year old male, recently diagnosed with a pheochromocytoma, was referred to our center because of severe cardiogenic shock after induction of anesthesia for resection of the mass. Despite adequate alpha-and beta-adrenergic blockade for one month, he developed malignant hypertension with subsequently hemodynamic collapse. After successful cardiopulmonary resusci-tation he developed pulmonary oedema with severe hypoxemia and persistent hemodynamic lability. On arrival in our hospital, echocardiography revealed significant left ventricular impairment. Decision was made to commence him on VA-ECMO for a refractory cardiogenic shock with severe pulmonary oedema. Because of persistent blood pressure swings despite VA-ECMO and beta-adrenergic blockade, we decided to remove the tumor on mechanical circulatory support by an open surgical approach the next day. After clamping of the adrenal circulation, the patient experienced profound hypotension requiring high doses of epinephrine and a methylene blue infusion. Surgical resection was successful but complicated by a postoperative bleeding for which the patient underwent an emergent endovascular embolization of an adrenal artery. Over the next days, there was progressive cardiac recovery and the patient was weaned off VA-ECMO on the fourth postoperative day. The patient was discharged from the intensive care 27 days after admission and left the hospital on day 30.\u0000\u0000Discussion: VA-ECMO seems to be a feasible last resort therapy in refractory cardiogenic shock induced by pheochromocytoma crisis as suggested by a high survival rate in literature. Despite its support benefit during this type of shock, surgical removal of the tumor is rarely done with mechanical circulatory support and heparinization.","PeriodicalId":7024,"journal":{"name":"Acta anaesthesiologica Belgica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42025845","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}

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