Abstract:
Objective To observe the changes of TNF‐α,interleukin IL‐6 ,IL‐10 and gas analysis though one lung ventilationone with two different pattern to study the effects lung injury and values of oxygenation on patients undergoing esophageal surgery . Methods 60 patients with esophageal cancer were randomly divided into two groups of A and B with 30 cases each .A term :contin‐ual one lungventilation and 4 cm H2 O peep until the end operate ,B term :intermittent one lung ventilation each 45 min with two lung ventilation 5 min .Blood gas analysis were determined immediately before one lung ventilation ,30 min following OLV ,60 min following OLV ,90 min following OLV ,120 min following OLV ,the end of the OLV ,after operate 24 h observe the MAP ,HR ,P , R ,SpO2 .PETCO2 and airway peak were recorded during operate .Results (1)SpO2 in group A was decreased at T3 and reached lest level at T5 ,which was higher than that in group B at T3 ,T5(P<0 .05) .(2)the levels of IL‐6 ,TNF‐α and IL‐10 in the two groups began to rise at T3(P<0 .01) ,reached peak level at T6 ,and decreased gradually at T7 ,which were still higher than those at T1(P<0 .05) .(3) The levels of TNF‐αand IL‐6 were lower in group A than those in g roup B at T3-T6(P<0 .05) ,T1 ,T2 ,T7 (P>0 .05) .The levels of IL‐10 was higher in group A than those in group B at T3-T7(P<0 .05) .Conclusion Compared with A term ,B term without VT has more lung injury although it increases values of oxygenation .
