Fibrinogen and Fibrin Degradation Products’ Levels in Cardiopulmonary Bypass with Mild-Hypothermia versus Normothermia
Authors
Abstract
Background: Coagulation cascades are activated during Cardiopulmonary Bypass (CPB) and their proper monitoring and maintenance determine the outcomes of operation to a big extent. Here, we assessed serum fibrinogen and Fibrin Degradation Products (FDP) in adult patients undergoing CABG with using CPB, either with hypothermia or normothermia. Materials and Methods: In a cross-sectional study, 80 adult patients’ candidate for elective CABG were randomly assigned into two groups: hypothermia and normothermia to assess fibrinogen and FDP, perioperatively. Results: Patients included 32 men (80%) in the hypothermia group and 26 men (60%) in the normothermia with the mean age of 61.43 ± 12.64 years. The mean temperature in the hypothermia group was 32.33 ± 1.44 and 35.33 ± 0.71 in the normothermic group. Differences in fibrinogen levels between the two groups were not significant (Fib before CPB, P=0.893, and Fib after declamping, P=0.057). The serum level of FDP before and during CPB was not significantly different in hypothermia and normothermia groups (P=0.412, P=0.778, respectively). Conclusion: During cardiac surgery in hypothermia and normothermia conditions rate of fibrinogen decreased 25% after declamping in each group; this decrease seems to be due to hemodilution. FDP levels were similar in both groups.
