In some cases we observed after-bleeding subsequent to the postoperative prescription of alpha-chymotrypsin. In contrast to this, several authors have pointed out that haemostasis is not affected by therapeutical doses. In vitro studies on 10 individuals (test methods: hirudin tolerance test and euglobulin lysis estimation) showed increased fibrinolytic activity. It is, therefore, dissuaded from administering alpha-chymotrypsin to outpatients for the prevention of postoperative oedema and haematoma formation.

Due to its fibrinolytic activity, alpha-chymotrypsin should be applied, even in doses of 5 and 10 mg (as indicated in the List of Drugs) only for postoperative oedema and haematoma prophylaxis, with due regard to the simultaneous effect on haemostasis. The maximum of fibrinolytic activity was observed 6 to 9 hours after intramuscular injection. These findings are consistent with clinical observation. The authors dissuade from uncontrolled use because, in spite of many separate experimental studies and clinical trials, there are still numerous questions that must be considered unsettled.

Postoperative bleeding was observed in 2 patients for whom alpha-chymotrypsin had been prescribed to prevent haematoma or oedema formation. In vitro experiments with citrated blood added with alpha-chymotrypsin evidenced (thrombelastogram, hirudin tolerance test, euglobulin-lysis time) an action on haemostasis. As compared to blanks, the application of an alpha-chymotrypsin dose which was 100-fold higher than those currently used in therapy resulted in a significant shortening of the r-time (thrombelastogram), delayed blood clotting (hirudin tolerance test) and a shortening of the euglobulin-lysis time. In vivo experiments are needed for further elucidation.
