[The effect of scalp infiltration with bupivacaine on blood coagulability and fibrinolysis in neurovascular surgery].
We investigated the effect of scalp infiltration with bupivacaine on blood coagulability and fibrinolysis in neurovascular surgery. Patients were randomly divided into two groups: scalp infiltration group (who received scalp infiltration with 0.5% bupivacaine prior to surgical incision, n = 7) and control group (n = 6). The blood coagulability and fibrinolysis were measured before and after surgical incision using a thromboelastogram (Thromboelastograph C-3000, Haemoscope). ⋯ The scalp infiltration prior to the surgical incision prevented these reactions (P < 0.05). The fibrinolytic rate did not change in either group. We conclude that scalp infiltration prior to surgical incision is beneficial for attenuating an increase in blood coagulability, which could induce perioperative complications due to associated systemic diseases (i.e. hypertension, diabetes, ischemic heart disease, etc.).
