Abstract

Activation of inflammatory response during cardiopulmonary bypass (CPB) may lead to considerable post-operative mortality. Recently, pentoxifylline (PTX), a methylxanthine derivative, has been reported to be effective in inhibiting proinflammatory cytokine production. This study aimed to determine whether or not PTX prevented CPB-induced systemic inflammatory response syndrome (SIRS) in patients undergoing cardiovascular surgery. Thirty adult patients were randomly separated into 2 experimental groups and 1 control group of 10 patients each. The experimental group received peroral PTX administration (Group 1: 600 mg/day, Group 2: 900 mg/day), while the control group did not. In Group 1 and Group 2, PTX administration was started on preoperative day 5 and continued for 5 days. Serum levels of PTX and IL-6 were measured just before and at 4 h after CPB using HPLC and ELISA, respectively. Respiratory index (RI) before and at 4 h after CPB was calculated, and serum levels of C-reactive protein (CRP) and fibrinogen on postoperative day 1 were also determined. There were no significant differences in age, body weight, sex, surgical procedures, CPB time, haemodynamics or risk factors among the 3 groups. Serum IL-6 level and RI index after CPB in Group 2 were significantly decreased compared with those in Group 1 and the control group. These results, therefore, suggested that preoperative daily administration of 900 mg/day PTX contributed to the attenuation of CPB-induced SIRS and had a beneficial effect on the postoperative course after cardiovascular surgery.
