“…MULDER et al [1057] observed no increase in bleeding with the recommended doses of [15][16][17][18][19][20] ml/kg bw; on the other hand bleeding increased with higher doses [207,365,641 a, 885, 891, 1416, 1847]. RAISON [1154] assumes that bleeding with use of higher doses is due to hemodilution.…”

Title-No. 1551 Dedicated to my wife LisaEs wurde fertig in Deiner Hut. Bleib Du mir auf dieser Erden, so 5011 alles fertig werden. THOMAS MANN ForewordThe manifold problems of shock are still of great importance, diagnostic and therapeutic experience of the "severely ill" being supplied with new information almost every month. In the 5 periodicals which have found their way to my desk during the past few days there are no less than 10 interesting articles on questions concerning shock research [see Bibliography 41 b, 53 a, 60 a, 192 a, 242 a, 350 b, 810 a, 941 a, 1069 a, 1082 a]. The most urgent point still is to maintain as complete as possible the objective catalog of the various shock manifestations found in man and in animals -yet at the same time to view interpretations of these phenomena in their relative and temporal "truth".Problems of shock research are not only interesting for their scientific value but also for their clinical implication. In particular, almost every practicing physician is facing problems of blood replacement very frequently. The effective or circulating blood volume remains an important theoretical and therapeutic problem in the shock field. For years, U. F. GRUBER has pursued this question clinically and experimentally. This volume deals with the world literature in an exceptionally thorough manner. This book is made more than a compilation by including a long list of original work done with F. D. MOORE in Boston, in the Surgical Department in Chur, with L. E. GELIN and S. E. BERGENTZ in Goteborg and in the Laboratory for Experimental Surgery in Davos; judgements are made on the basis of original studies, and essential points are separated from unimportant ones. This volume will be welcomed by the medical profession because it carefully treats vital questions concerning this complicated, much-discussed, and in part contested field, considering that today, along with various forms of blood and several plasma preparations, there are more than 40 different plasma replacement substances available with various physico-chemical, biological and pharmacological properties. Older preparations have been abandoned, others modified, and new ones appear.A comparative evaluation of the chemical characteristics, the range of indication and the therapeutic effectiveness of these solutions suggests itself particularly at this time because in recent years the use of large amounts of balanced electrolyte solutions tended to reverse the principles of blood replaceme...

“…4 Especially in the early days of conventional aortic valve replacement (AVR), however, in-hospital mortality was up to 25% because of cardiac failure, bleeding or thromboembolic complications, infections, or arrhythmias. [4][5][6][7][8][9] The design of the first mechanical heart valves left patients with peak gradients of ≥60 mm Hg. Applying the updated standardized end-point definitions for transcatheter aortic valve implantation (TAVI; Valve Academic Research Consortium [VARC] 2) definitions 10 to this patient population would have resulted in a procedural success rate of 0%, and the US Food and Drug Administration probably would have never approved the devices.…”

“…Homograft aortic valves have established themselves as alternatives to mechanical prostheses (Ross, 1962;Barrett-Boyes, Lowe, Cole, and Kelly, 1965;Hocksema, Titus, Giuliani, and Kirklin, 1966;Ross and Yacoub, 1969). One of the main advantages of aortic homograft valves is the absence of thromboembolic complications, which are one of the major hazards of prosthetic valves in spite of an adequate anticoagulant regime (Brandenburg, 1965;Mulder, Mazzei, and MacAlpin, 1966;Fraser and Waddell, 1967). This paper reports the study of haemolytic The patients studied (Table) included 15 men and six women with an age range of 20 to 62 years.…”

Red cell survival was studied in 21 patients following homograft replacement of the aortic valve. Autologous cells labelled with t1Cr were used. The T+ TtCr varied between 24 and 34 days, with only one patient below the normal limit of normal variations. The absence of haemolysis was confirmed by other haematological studies, including estimation of reticulocytes, serum lactic dehydrogenase, and urinary haemosiderin. Haptoglobin levels were low in most of the patients studied. In contrast to prosthetic valves there was no haemolysis in patients with regurgitation around or through the homograft valve. Intravascular haemolysis has been described after aortic valve replacement using a mechanical prosthesis. This applies to ball valves (Marsh, 1964;
