Coagulation defects in obstetrics

Abstract

A paper read at a WHO/UNICEF Seminar on "Anemia and the Use of Blood Transfusion in M.C.H. Work" 6th June, 1967. Kampala. Coagulation defects are only rarely met with in obstetrics. It is probable that the complication is nowadays being diagnosed with increasing frequency, owing mainly to a greater awareness of the condition. In Mulago Hospital where the author practises, it occurred 11 times in about 33,500 deliveries in the period 1964-66. This gives an incidence of about 0.03%. In cases of concealed accidental hemorrhage the incidence is however higher; it appears to occur in some 5% of cases. A historical background of this condition is presented, and a description of how the clotting mechanism takes place is also explained. Furthermore, a detailed diagram describes the mechanism by which coagulation failure is produced. The author analysed cases at Mulago Hospital, indicating the relative clinical diagnosis and treatment, the latter consisting of two forms, preventive and curative.
