Background and objectives
A prompt and effective management of trauma patient is necessary. The aim of this case report is to highlight the importance of intraoperative echocardiography as a useful tool in patients suffering from refractory hemodynamic instability no otherwise explained.Case report
A 41 year‐old woman suffered a car accident. At the emergency department, no abnormalities were found in ECG or chest X‐ray. Abdominal ultrasound revealed the presence of abdominal free liquid and the patient was submitted to urgent exploratory laparotomy. Nevertheless, she persisted suffering arterial hypotension and metabolic acidosis. Looking for the reason of her hemodynamic instability, intraoperative transthoracic echocardiography was performed, finding out the presence of pericardial effusion. Once the cardiac surgeon extracted pericardial clots, patient's situation improved clinically and analytically.Conclusion
Every anesthesiologist should be able to use the intraoperative echocardiography as an effective tool in order to establish the appropriate measures to promote the survival of patients suffering severe trauma. 相似文献3.

BackgroundDual antiplatelet therapy (DAPT) is the cornerstone treatment of acute myocardial infarction (AMI).ObjectiveThe present study aimed to investigate the efficacy and safety of triple antiplatelet therapy (TAPT) in elderly female patients with diabetes and ST segment elevation myocardial infarction (STEMI), who had undergone percutaneous coronary intervention (PCI).MethodsWe designed a randomized, single-blind study. Control group A (97 elderly male patients with diabetes and STEMI, whose CRUSADE scores were < 30) received aspirin, ticagrelor, and tirofiban. A total of 162 elderly female patients with diabetes and STEMI were randomly divided into two groups according to CRUSADE score. Group B (69 patients with CRUSADE score > 31) received aspirin and ticagrelor. Group C (93 patients with CRUSADE score < 30) received aspirin, ticagrelor and tirofiban. P values < 0.05 were considered statistically significant.ResultsCompared to the findings in group A, post-PCI Thrombolysis in Myocardial Infarction (TIMI) grade 3 blood flow and TIMI myocardial perfusion grade 3 were significantly less prevalent in group B (p < 0.05). When compared to groups A and C, the incidence of major adverse complications was significantly higher in group B (p < 0.05).ConclusionTAPT could effectively reduce the incidence of major complications in elderly female patients with diabetes and STEMI. However, close attention should be paid to hemorrhage in patients receiving TAPT. (Arq Bras Cardiol. 2020; [online].ahead print, PP.0-0) 相似文献

A 49-year-old woman was hospitalized for acute left foot arterial ischemia. Arterial Doppler revealed occlusion of the dorsalis pedis and posterior tibial arteries. A computed tomography angiography performed to assess abdominal pain showed hepatic, splenic, renal and pancreatic infarctions. A splenic artery embolism and a small aortic wall thrombus at the celiac trunk were identified. No radiological signs of aortic atherosclerosis were found. No predisposing conditions for secondary aortic thrombosis or intracardiac embolic sources were detected. It was determined that primary aortic thrombosis, a rare though potentially serious condition, was to blame. Isolated aortic mural thrombosis therapy is not well established, although systemic anticoagulation, thrombolysis, thromboaspiration, endovascular stent grafting and surgical thrombectomy have been attempted with varying success. In our patient, systemic anticoagulation therapy was initiated and resulted in aortic thrombus resolution. Close clinical follow-up is crucial, as the aortic thrombus can recur despite anticoagulation and aggressive control of the atherosclerotic risk factors. 相似文献

Introduction and ObjectivesRecent studies have shown that the major risk factors for arterial thrombotic diseases are closely associated with venous thromboembolism (VTE). This study aimed to investigate the expression of CD3, CD4 and CD8 in T lymphocytes, the CD4/CD8 ratio and high-sensitivity C-reactive protein (hs-CRP) levels in patients with VTE, coronary artery atherosclerosis (CAA) and healthy subjects.MethodsA total of 82 healthy subjects, 51 VTE patients and 114 CAA patients were recruited, and the expression of CD3, CD4 and CD8 in T lymphocytes and the CD4/CD8 ratio were determined. Serum hs-CRP was also measured.ResultsCompared to healthy subjects, VTE patients had significantly reduced CD3 expression (p=0.019), comparable CD4 expression (p=0.868), significantly reduced CD8 expression (p<0.001) and increased CD4/CD8 ratio (p=0.044). However, VTE patients had comparable expression of CD3, CD4 and CD8 and CD4/CD8 ratio to CAA patients. In addition, among patients with VTE or CAA, the proportion of patients with reduced CD3+ and CD8+ T lymphocytes or increased CD4/CD8 ratio was significantly higher than in healthy subjects. In addition, hs-CRP in both VTE and CAA groups was significantly higher than in healthy subjects.ConclusionsThe antigen recognition and signal transduction activation of T cells is significantly reduced in patients with VTE or CAA, and the killing effect of T cells on pathogens, including viruses, is also significantly compromised. In addition, inflammatory and immune mechanisms are involved in the occurrence and development of venous and arterial thrombosis. 相似文献

AimsPortugal has one of the lowest rates of primary percutaneous coronary intervention (p-PCI) in Western Europe. This study assessed the progress of Portuguese p-PCI performance indicators one year after Portugal joined the Stent for Life (SFL) initiative.Methods and ResultsTwo national surveys were carried out, each covering a period of one month: the first when Portugal joined the SFL in 2011 (Moment Zero), and the second one year later (Moment One). A total of 397 consecutive patients with probable ST-segment elevation myocardial infarction were enrolled (201 at Moment Zero and 196 at Moment One) from 15 centers. During this period, the number of patients who arrived at a local hospital without p-PCI decreased (62–47%; p=0.004) and transportation to a p-PCI hospital by the National Institute for Medical Emergencies (INEM) increased significantly (13–37%; p<0.001). Shorter times to revascularization were observed, due to shorter patient delay (118–102 min; p=0.008). Door-to-balloon delay and system delay remained unchanged.ConclusionsImprovements in performance indicators for p-PCI demonstrate the success of the first year of the local SFL plan, which was mainly focused on raising public awareness of the need to use the INEM emergency services, which has reduced patient delay, and on improving secondary transportation. 相似文献

BackgroundStrength training has beneficial effects on kidney disease, in addition to helping improve antioxidant defenses in healthy animals.ObjectiveTo verify if strength training reduces oxidative damage to the heart and contralateral kidney caused by the renovascular hypertension induction surgery, as well as to evaluate alterations in the activity of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) endogenous antioxidant enzymes.MethodsEighteen male rats were divided into three groups (n=6/group): sham, hypertensive, and trained hypertensive. The animals were induced to renovascular hypertension through left renal artery ligation. Strength training was initiated four weeks after the induction of renovascular hypertension, continued for a 12-weeks period, and was performed at 70% of 1RM. After the training period, the animals were euthanized and the right kidney and heart were removed for quantitation of hydroperoxides, malondialdehyde and sulfhydryl groups, which are markers of oxidative damage. In addition, the activity of SOD, CAT, and GPx antioxidant enzymes was also measured. The adopted significance level was 5% (p < 0.05).ResultsAfter strength training, a reduction in oxidative damage to lipids and proteins was observed, as could be seen by reducing hydroperoxides and total sulfhydryl levels, respectively. Furthermore, an increased activity of superoxide dismutase, catalase, and glutathione peroxidase antioxidant enzymes was observed.ConclusionStrength training is able to potentially reduce oxidative damage by increasing the activity of antioxidant enzymes.
