ABSTRACT
OBJECTIVE:
To evaluate the possibility of radial artery pressure and waveform as a convenient definition of pulsatile flow and the the effect of pulsatile perfusion during cardiopulmonary bypass (CPB) procedures.METHODS:
From March 2008 to December, Eighty patients underwent open heart surgery were randomly divided into a pulsatile group (P, n=45) and a nonpulsatile group (NP, n=35). Monitored by radial artery pressure and waveform, the pulsatile low was applied from the point of the aortic cross-clamp until its release in P group. A P group of patients whose radial artery pressure and waveform revealed "double peak" or "single peak" (>30 mm Hg, 1 mm Hg=0.133 kPa) were compared with NP group. Parameters examined were lactate, urine volume, high sensitivity C reactive protein, blood urea nitrogen, creatinine, blood uric acid, lactate dehydrogenase, glutamic oxalacetic transaminase, ratio of urine for occult blood test, prothrombin time and tracheal intubation time.RESULTS:
The waveform with "double peak" or "single peak" (>30 mm Hg) presented in 35 (77.78%) in P group. The urine volume during CPB was significantly higher in P group. The lactate (P<0.01) during CPB, high sensitivity C reactive protein (P<0.05), increasing extend of lactic acid dehydrogenase (P<0.05) and the prothrombin time (P<0.01) after CPB were significantly lower in P group. The blood uric acid after CPB was increased in P group and decreased in NP group.CONCLUSIONS:
Effective pulsatile flow can be generated by optimization of equipment and adjustment of pulsatile parameter. The radial artery pressure and waveform is a convenient definition of pulsatile flow. The pulsatile flow is predominant monitored by radial artery pressure and waveform.
