Monitoring of anticoagulation during cardiopulmonary bypass by means of the activated coagulation time (ACT) has become questionable due to the prolongation in the clotting time of patients receiving aprotinin. Because the celite-based ACT only indicates intrinsic coagulation, and sufficient anticoagulation is needed to also prevent extrinsic coagulation, the ACT may not be reliable. Three different clotting times, the celite-based ACT, the kaolin-based activated coagulation time (AKT) and the high-dose thrombin time (HITT), were compared in a prospective, double-blind, placebo-controlled study of 20 patients who were to undergo cardiopulmonary bypass. As expected, neither the kaolin-based assay nor the high-dose thrombin time was influenced by aprotinin, whereas the celite-based ACT was significantly prolonged in aprotinin-treated patients as compared to control patients (P < 0.05). This study confirms that both kaolin-based and thrombin-based tests provide a reliable means of determining the degree of heparinization in the presence of aprotinin during cardiopulmonary bypass.

UI MeSH Term Description Entries
D007611 Aprotinin A single-chain polypeptide derived from bovine tissues consisting of 58 amino-acid residues. It is an inhibitor of proteolytic enzymes including CHYMOTRYPSIN; KALLIKREIN; PLASMIN; and TRYPSIN. It is used in the treatment of HEMORRHAGE associated with raised plasma concentrations of plasmin. It is also used to reduce blood loss and transfusion requirements in patients at high risk of major blood loss during and following open heart surgery with EXTRACORPOREAL CIRCULATION.

D007616 Kaolin The most common mineral of a group of hydrated aluminum silicates, approximately H2Al2Si2O8-H2O. It is prepared for pharmaceutical and medicinal purposes by levigating with water to remove sand, etc. (From Merck Index, 11th ed) The name is derived from Kao-ling (Chinese: "high ridge"), the original site. (From Grant & Hackh's Chemical Dictionary, 5th ed) Kaolinite
D007692 Diatomaceous Earth A form of SILICON DIOXIDE composed of skeletons of prehistoric aquatic plants which is used for its ABSORPTION quality, taking up 1.5-4 times its weight in water. The microscopic sharp edges are useful for insect control but can also be an inhalation hazard. It has been used in baked goods and animal feed. Kieselguhr is German for flint + earthy sediment.

D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D010919 Placebos Any dummy medication or treatment. Although placebos originally were medicinal preparations having no specific pharmacological activity against a targeted condition, the concept has been extended to include treatments or procedures, especially those administered to control groups in clinical trials in order to provide baseline measurements for the experimental protocol. Sham Treatment
D011446 Prospective Studies Observation of a population for a sufficient number of persons over a sufficient number of years to generate incidence or mortality rates subsequent to the selection of the study group. Prospective Study,Studies, Prospective,Study, Prospective
D011479 Protamines A group of simple proteins that yield basic amino acids on hydrolysis and that occur combined with nucleic acid in the sperm of fish. Protamines contain very few kinds of amino acids. Protamine sulfate combines with heparin to form a stable inactive complex; it is used to neutralize the anticoagulant action of heparin in the treatment of heparin overdose.
