Fragmin and heparin were studied in pigs during 120 min of cardiopulmonary bypass (CPB) and up to 240 min postoperatively, with respect to clotting, bleeding and the effects of protamine. Thirty-three pigs received bolus injections of 300 IU/kg with or without additional dosage during CPB and with or without subsequent protamine sulphate. Doses of Fragmin 60% higher were necessary to prevent clott

Absorbable, nonwoven patches made from polyhydroxybutyrate (PHB) were implanted as transannular patches into the right ventricular outflow tract and pulmonary artery in 13 weanling sheep, the test group. Six sheep, in which a transannular Dacron patch was implanted, served as control group. The test and the control patches were harvested 3-24 months later. The results were documented macroscopical

Twenty patients had a repair of an atrioventricular septal defect with tetralogy of Fallot (n = 13) or double outlet right ventricle (n = 7). Mean age was 3.5 years. Surgical technique included transatrial-transpulmonary resection of right ventricular outflow tract obstruction and transatrial two patch repair of the atrioventricular septal defect. Ten patients required a transannular patch and one

From Jan 1989 to December 1991, 61 patients had modified Fontan procedures for a variety of lesions, including tricuspid atresia (18), mitral atresia (3), double inlet ventricle (14), isomeric hearts (4) and others (22). The hospital mortality was 1.6% (70% CL.0.2-5.3%). There were 2 late deaths. The median age at operation was 3.7 years (mean 5.6, range 1.5 to 20.3 years). There were two late fai

From 1979 through 1991, 19 infants with absent pulmonary valve syndrome and airway obstruction were seen for surgical treatment. All patients underwent extensive pulmonary artery aneurysmorrhaphy using cardiopulmonary bypass. Fourteen patients had simultaneous transatrial ventricular septal defect (VSD) closure, infundibular resection, and placement of a short transannular patch; 2 had transventri

Pericardial adhesions after cardiac operations are a widely known phenomenon. They may severely complicate reoperations, making reentry hazardous, increasing bleeding, and prolonging the operation time. The anatomic orientation and visibility of both bypass grafts and coronary arteries are also impaired. With the aim of minimizing pericardial adhesions after cardiac operations, we studied the cour

Biodegradable patches made from polyhydroxybutyrate (PHB) were used to close experimentally induced atrial septal defect in six calves. The implants were evaluated after 3-12 months macroscopically and by light and scanning electron microscopy with regard to regeneration of tissue and degradation of the polymer. At implant degradation, complete endothelial layers facing the right and left atrium w

A new absorbable polymer prepared from polyhydroxybutyrate (PHB) was inserted as a pericardial patch in sheep to serve as a temporary scaffold for regeneration of pericardial tissue. Postoperative adhesions were rare or absent. The present study focuses on characterization of the regenerated surface cells. The luminal surface of the regenerated tissue was covered with a complete layer of mesotheli

A case of absent right aortic cusp causing serious aortic incompetence in a neonate is reported. A "bicuspidalization" repair broke down within 24 hours, but reoperation with annular enlargement and insertion of a 19-mm prosthetic valve resulted in complete recovery. This rare but life-threatening anomaly of the aortic valve can be recognized with Doppler echocardiography. Valve replacement in con

The visibility of the pericardium as well as of the space between the dorsal aspect of the sternal surface and the pericardial surface after cardiac surgery was determined by CT and/or MR with electrocardiographic (ECG)-gated spin-echo (SE) and gradient-echo sequences. Seventeen patients who had undergone cardiac operations and who were admitted for cardiac reoperation were investigated with CT an

Early results of mitral valve replacement were reviewed in 336 unselected patients, 261 without and 75 with concomitant coronary artery bypass grafting (MVR and MVR + CABG groups). Early (less than 30 days) mortality was 7% in the MVR and 16% in the MVR + CABG group, with cardiac failure as the dominant cause. In multivariate analysis, the variables most strongly related to early mortality were co

Patients with cold urticaria can after exposure to cold air or infusions react with hypotension and cardiovascular collapse. We here report on a patient having a severe cold urticaria who because of angina required myocardial revascularization: She was successfully operated in normothermic cardiopulmonary bypass with cardioplegia.

In a retrospective study of 150 twins born between 1970-1977, birth weight, length, and head circumference was plotted against gestational age. In comparison to singletons, all 3 parameters were low normal. While length and head circumference values follow the growth pattern of singletons, prenatal birth weight shows a progressive decline toward maturity. The intrauterine growth pattern of twins r

Objectives: Young adults with autism have a different way to develop in body and movement. Do the experiences of body and movement consist with physiotherapeutic findings, in order to guide understanding and interventions?Method: The study involved eleven participants with autism, 16-22 years old, who told about their experiences. They were also examined concerning motor proficiency with Bruininks

Aims:To explore young adults´ own experiences about body and movements.Method: Eleven young adults (15-22 years) with autism were interviewed face-to-face, with picture support available.Results:The results are preliminary, pointing towards the importance of assessing movement quality in persons with autism.

Bakgrund Studier om hur personer med autism upplever kropp och rörelse är få. Annorlunda kroppsliga funktioner och kroppsuppfattning kan påverka individen negativt. Interventioner som är baserade på kroppskännedom och anpassad rörelse skulle kunna stärka individens inre resurser.SyfteAtt få en djupare förståelse av upplevelserna av kropp och rörelse bland ungdomar/unga vuxna med autism, samt att u
