    Notes: Abstract. Cyclooxygenase (COX)-2 is the predominant COX isoform present at sites of inflammation, and produces prostaglandins (PG) that cause swelling and pain. However, in situations where the release of protective PGs by COX-1 has been lost, the induction of COX-2 may compensate and reduce inflammatory responses. This is particularly likely in large blood vessels, where, under physiological conditions, the release of prostacyclin by COX-1, present in the endothelium, is an important component of cardiovascular homeostasis. We, and others, have recently shown that COX-2 can be induced by proinflammatory cytokines in human blood vessels, and also in human airway cells. Moreover, recent data from our group have suggested that in these structures, COX-2 is anti-inflammatory at the level of cellular proliferation, adhesion receptor expression, and cytokine release.

    Notes: Abstract Conventional indices of tissue perfusion after surgery involving cardiopulmonary bypass (CPB) may not accurately reflect disordered cell metabolism. Venous hypercarbia leading to an increased veno-arterial difference in CO2 tensions (V-aCO2 gradient) has been shown to reflect critical reductions in systemic and pulmonary blood flow that occur during cardiorespiratory arrest and septic shock. We therefore measured plasma lactate levels and V-aCO2 gradients in 10 patients (mean age 57.2 years) following CPB and compared them with conventional indices of tissue perfusion. Plasma lactate levels, cardiac index (CI) and oxygen uptake $$(\dot VO_2 )$$ all increased significantly (p〈0.05 vs baseline levels) up to 3h following surgery. Oxygen delivery $$(\dot DO_2 )$$ did not change. Plasma lactate levels correlated significantly with CI (r=0.47,p〈0.01). V-aCO2 fell significantly with time (p〈0.01 vs baseline). There was an inverse relationship between V-aCO2 and cardiac index and V-aCO2 and lactate (r=−0.37,p〈0.05;r=−0.3,p〈0.05 respectively). We conclude that blood lactate, CI and $$\dot VO_2 $$ increase progressively following CPB. An increase in lactate was associated with a decrease in V-aCO2. An increase in V-aCO2 was not therefore associated with evidence of inadequate tissue perfusion as indicated by an increased blood lactate concentration.
