    Description / Table of Contents: Zusammenfassung Der Histamin H2-Antagonist Cimetidin wurde 63 Patienten vor elektiven allgemeinchirurgischen Eingriffen in 2 verschiedenen Regimes verabreicht: Eine Gruppe erhielt 400 mg per os 10–12 h vor der Operation, eine zweite 400 mg per os 10–12 h plus 200 mg intravenös 1–2 h vor Operationsbeginn. Es wurde eine signifikant größere Anzahl von Patienten mit einem pH 〉2,5 in den Cimetidin-behandelten Gruppen nur gefunden, wenn man den ganzen Zeitraum der Narkose mit berücksichtigte. Nach diesen Ergebnissen wird Cimetidin bei elektiven Eingriffen als nicht notwendige Routineprämedikation erachtet.
    Notes: Summary Cimetidine, a histamine H2-receptor-antagonist, was administered either as a single 400 mg dose perorally 10–12 h before operation, or in a 400 mg dose perorally 10–12 h before operation plus 200 mg intravenously 1–2 h before operation, in 63 patients awaiting general elective surgery. Distribution of patients showed a significantly greater number of patients with a pH 〉2.5 in cimetidine groups, as compared to controls only, if the whole time of anaesthesia is taken into consideration. Between the two cimetidine regimens there was no statistically significant difference. These findings suggest that cimetidine is not necessary as a routine pre-operative medication in general elective surgery.

    Description / Table of Contents: Summary Heparin-induced thrombocytopenia (HIT) is the most important side-effect of heparin therapy. Two types of thrombocytopenia can be caused by heparin: a frequent non-immunologic type causing a minor decrease in thrombocyte count without apparent clinical importance and, on the other hand, an immunologic type accompanied by thromboembolic complications. Patients and methods: We report on two cases with HIT type II after coronary artery bypass grafting (CABG). HIT antibodies were demonstrated by ELISA for platelet-factor-4-heparin-complex and heparin-induced platelet-activation (HIPA) assay. Results: A 67 year old patient suffered from a HIT type II seven days after administration of heparin during myocardial revascularization. In this patient, a continuous fever and a signicantly reduced general condition were the primary symptoms. The clinical picture of this disease was reversible after aborting the heparin therapy. Thromboembolic complications did not occur. A 70 year old patient developed a HIT type II with thromboembolic complications 13 days after CABG. The vascular occlusions affected the A. spinalis anterior with the development of a spinalis anterior-syndrome, the coronary arteries with the development of myocadial infarction, and the A. iliaca interna. A white-clot syndrome with thrombi in the ascending aorta, in the left atrium, and in the left ventricle required an operation with extracorporal circulation including the use of recombinant hirudin for anticoagulation. Conclusion: With therapy with heparin, it is obligatory to check platelet count. An indication for the development of HIT type II is a decrease in platelet count or thromboembolic complications during heparin therapy. In the case of HIT type II recombinant hirudin was a practical altenative as an anticoagulant for extracorporal circulation and for continous hemofiltration.
    Notes: Zusammenfassung Die heparininduzierte Thrombozytopenie (HIT) ist die wichtigste unerwünschte Wirkung einer Heparintherapie. Zwei Formen der Thrombozytopenie können durch Heparin verursacht werden: eine häufige, nicht-immunologische Form, welche einen geringgradigen Thrombozytenabfall hervorruft und keine größere klinische Bedeutung zu haben scheint, sowie eine immunologische Form, welche mit thromboembolischen Komplikationen verbunden sein kann. Patienten und Methodik: Wir berichten über zwei Fälle von HIT Typ II in Zusammenhang mit aorotokoronarer Bypassoperation (ACB). HIT-Antiköper wurden durch ELISA gegen Plättchenfaktor-4-Heparinkomplexe und den Heparininduced-platelet-activation-(HIPA)-Assasy nachgewiesen. Ergebnisse: Ein 67jähriger Patient entwickelte 7 Tage nach Heparin-Erstexposition im Rahmen einer myokardialen Revaskularisation eine HIT Typ II. Dabei standen eine Fieberkontinua und deutlich reduzierter Allgemeinzustand im Vordergrund der klinischen Symptomatik. Thromboembolische Komplikationen traten nicht auf. Das Krankheitsbild war nach Absetzen der Heparintherapie reversibel. Bei einem 70jährigen Patienten bildete sich am 13. postoperativen Tag nach ACB-Operation eine HIT Typ II aus mit thromboembolischen Komplikationen. Die Gefäßverschlüsse betrafen die A. spinalis anterior mit Ausbildung eines A. spinals anterior-Syndroms, die Coronararterien mit Ausbildung eines Vorderwandinfarktes, Digitalarterienverschlüsse und Gefäßverschlüsse im Stromgebiet der A. iliaca interna. Die Ausbildung eines white-clot-Syndroms mit Thromben in der Aorta ascendens, im linken Vorhof und sogar im linken Ventrikel erforderte eine Operation mit extrakorporaler Zirkulation, bei der rekombinantes Hirudin zur Antikoagulation eingesetzt wurde. Schlußfolgerung: Bei jeder Heparinapplikation muß eine regelmäßige Kontrolle der Thrombozytenzahl erfolgen. Hinweise auf die Entstehung einer HIT Typ II sind ein Abfall der Thrombozytenwerte oder thromboembolische Komplikationen während einer Heparintherapie. Rekombinantes Hirudin erwies sich bei gesicherter HIT Typ II als gute Alternative zur Antikoagulation bei extrakorporaler Zirkulation oder kontinuierlicher Hämofiltration.

    Notes: Abstract  Background: The object was to evaluate the long-term effectiveness of strategies for managing the aortic root and distal aorta in type A dissections. Methods: From 1990 to 1999, 50 patients (32 men (64.07%); 18 women, (36.0%); mean age 57.4 ± 11.1 years) underwent operation for ascending aortic dissection. Surgical strategies included aortic root replacement with a composite graft (21/50; 42.0%), valve replacement with supracoronary ascending aortic graft (3/50, 6%), and valve preservation or repair (26/50; 52.0%). Results: Overall hospital mortality rate was 18.0%. Follow-up was completed for 47 patients (94.0%) and ranged from 1 month to 10.5 years (mean 28.8 months). Actuarial survival for patients discharged from the hospital was 84% at 1 year, 75% at 5 years, and 66% at 10 years. There was no significant difference between the various procedures regarding mortality, neurological complications, long-term survival, and proximal reoperations. The ascending aorta alone was replaced in 8 of 50 patients (16%), ascending and hemiarch in 30 of 50 patients (60%), and arch and proximal descending aorta in 12 of 50 patients (24%). Hospital mortality (11.5%, 20.0%, and 16.7%, respectively; p 〉 0.05) and 5- and 10-year survival (p 〉 0.05) were not statistically dependent on the extension of the resection distally. Residual distal dissection was not associated with a decrease in late survival. With regard to emergency surgery (36/50) there was no significant difference in hospital mortality (p 〉 0.05) and 5-year survival (p 〉 0.05) between those who had undergone coronary angiography (19/36; 52.8%) on the day of surgery with those who had not (17/36; 47.2%). Conclusions: Preservation or repair of the aortic valve can be recommended in the majority of patients with type A dissection. Distal extension of the resection does not increase surgical risk. Residual distal dissection does not decrease late survival. Preoperative coronary angiography may not affect survival in patients undergoing emergency surgery. (J Card Surg 2004;19:240-245)
