OBJECTIVE: We examined the hypothesis that higher cerebral oxygen saturation (rSO2) during RCP is correlated with urinary output.
METHODS: Between December 2002 and August 2006, 12 patients aged 3 to 61 days and weighing 2.6 to 3.4 kg underwent aortic arch repair with RCP. Urinary output and rSO2 were analyzed retrospectively. Data were assigned to either of 2 groups according to their corresponding rSO2: Group A (rSO2 < or = 75%) and Group B (rSO2 < 75%).
RESULTS: Seven and 5 patients were assigned to Group A and Group B, respectively.Group A was characterized by mean radial arterial pressure (37.9 +/- 9.6 vs 45.8 +/- 7.8 mmHg; P = 0.14) and femoral arterial pressure (6.7 +/- 6.1 vs 20.8 +/- 14.6 mmHg; P = 0.09) compared to Group B. However, higher urinary output during CPB (1.03 +/- 1.18 vs 0.10 +/- 0.15 ml.kg-1.h-1; P = 0.03). Furthermore our results indicate that a higher dose of Chlorpromazine was used in Group A (2.9 +/- 1.4 vs 1.7 +/- 1.0 mg/kg; P = 0.03).
CONCLUSION: Higher cerebral oxygenation may provide higher urinary output due to higher renal blood flow through collateral circulation.
