Objective
To estimate the relationship of methods and drugs for management of constrictive pericarditis during pericardiectomy.
Methods
We reviewed the records of 45 patients (mean age, 40.24±15.34 years) with a diagnosis of constrictive pericarditis who underwent pericardiectomy in our hospital from 2012 through 2014 year. During operation, inotropic agents, vasodilators and diuretics were used. According to the diuretics, patients were divided into two groups including a furosemide group(group F) with 38 patients and a lyophilized recombinant human brain natriuretic peptide (lrhBNP) group with 7 patients(group B).
Results
Preoperatively, 30 patients were pulmonary congestion, which was diagnosed by chest radiographs. Pericardiectomy was finished by off pump in 43 patients. Another 2 patients required cardiopulmonary bypass (CPB) for pericardiectomy. In the group F 52.6% of the patients needed vasodilators to reduce cardiac preloading following pericardiectomy. None of other vasodilators were used in the group B. After pericardiectomy, the fluctuation of systolic and diastolic pressure decreased significantly in the group B (P=0.01, respectively). In the group F, the fluctuation of diastolic pressure decreased significantly (P<0.05). Low cardiac output was the most common postoperative problem. One patient accepted postoperative extracorporeal membrane oxygenation (ECMO) support. Postoperative poor renal function was found in 42.2% of the patients. Three of them needed hemofiltration. Postoperative poor renal function accompanied by poor hepatic function was found in 15.6% of the patients. One of them used dialysis and artificial liver. Three patients were respiratory failure with longer mechanical ventilation and tracheotomy. The overall perioperative mortality rate was 6.7% (3 patients). All patients, who died or used with hemofiltration, artificial liver and ECMO were found in the group F.
Conclusion
More stable haemodynamics after pericardiectomy may occur with using lrhBNP. lrhBNP may reduce postoperative major morbidity and mortality. Because of the small group using lrhBNP in our study, more patients using lrhBNP for pericardiectomy need to be studied.
特發性震顫(essential tremor,ET)是最常見的成年起病的神經系統變性疾病之一。ET 分為家族性和散發性 2 種,約一半以上患者存在家族史,遺傳因素可能發揮著重要作用。目前,大量研究致力于尋找 ET 發病的風險位點及致病基因。進行 ET 遺傳學分析有助于進一步研究其病理生理機制,因此文章從該病的單基因遺傳模式及復雜疾病遺傳模式 2 個方面對 ET 的遺傳學進展進行了闡述。
