[Continuous capillary blood collection by means of cooling of the wound].

By cooling of a capillary wound to 5 degrees C it is possible to obtain blood continuously without anticoagulants. Thus it is possible to measure blood constituents (like bilirubin, glucose, gases, cellular elements etc.) over longer periods of time in patients for whom indwelling venous catheters are not feasible.

[A new in vivo method for the detection of carriers of haemophilia (author's transl)].

We examined 14 carriers of haemophilia A with the "Haemorrhagometer". The cold tolerance test (at 17 degrees C) revealed that 9 out of 10 proven and 3 out of 4 probable carriers had a pathologically prolonged bleeding time. Accordingly blood loss was pathologically elevated in 9 out of 10 proven and 2 out of 4 probable carriers. At room temperature the difference between normal control persons and carriers of haemophilia A was not as pronounced. 5 of 8 proven and 3 of 4 probable carriers showed pathologically elevated bleeding intensity, only 1 of 8 proven and none of 4 probable carriers showed abnormally prolonged bleeding time. Haemorrhagometry at 17 degrees C (cold tolerance test) may be helpful to ascertain whether or not a woman is a carrier of haemophilia A.

[Normal data for hemorrhagometry (author's transl)].

Normal data for hemorrhagometry were established in 43 control persons, aged between 4 and 14 years. At room temperature the mean value for bleeding time was 4.61 min. (upper limit of normal 7.7 min.), the mean hemoglobin loss, which corresponds to the blood loss, was 4.34 mg (upper limit 14.74 mg), the mean value for maximal bleeding intensity was 21.4 mug hemoglobin/sec. (upper limit 48.8). When hemorrhagometry is performed at 17 degrees C (cold tolerance test) bleeding time is prolonged (mean 9.02 min., upper limit 14.3 min.), bleeding intensity increases (mean 32.4 mug Hb/sec., upper limit 81.3 mug/sec.), and hemoglobin loss rises (mean 11.07 mg, upper limit 31.36 mg). Bleeding time determinations according to IVY yield shorter values (mean 2.99 min., upper limit 4.5 min.) than those obtained by hemorrhagometry at room temperature. There was no positive correlation between hemorrhagometry parameters and age, sex, and number of thrombocytes, as long as thrombocyte counts above 100.000/mm3.
