QUESTIONS UNDER STUDY: Surgery of @entity1028 involves a high risk of @entity260 . It has been suggested that the incidence of @entity260 is related to the development of @entity344 . The goal of this study was, therefore, to determine the incidence of @entity344 during repair of @entity1028 , and to test the hypothesis that these episodes predict an adverse postoperative course. METHODS: In 49 consecutive @entity1 undergoing elective surgery for repair of an @entity439 , @entity356 ( @entity14243 ) was measured perioperatively. The length of the surgical procedure, perioperative intravenous fluid intake, use of vasoactive drugs, APACHE-II scores, days with an endotracheal tube in place, days of intensive care and major @entity260 were prospectively assessed. The @entity1 were assigned to either a group with a @entity14243 > or = 7.35 or a group with @entity14243 < 7.35 measured towards the end of the surgical procedure, and then compared. RESULTS: The @entity14243 decreased from 7.42 +/- 0.09 after induction of anesthesia to 7.37 +/- 0.07 (p < 0.05) during clamping of the aorta, and continued to decrease to 7.34 +/- 0.08 (p < 0.001) towards the end of surgery and on admission to the surgical intensive care unit (mean +/- standard deviation). The percentage of @entity1 with @entity14243 < 7.35 increased from 10% at the beginning of the operation to 55% on admission to the intensive care unit (p < 0.0001). There was no difference in the postoperative course between @entity1 with @entity14243 > or = 7.35 and those with @entity14243 < 7.35 measured after declamping of the aorta. @entity1 who had a major complication during their stay in the intensive care unit had lower perioperative @entity14243 values than @entity1 without complications (p < 0.001). CONCLUSIONS: Perioperative @entity344 are common during repair of @entity1028 . The perioperative course, however, is not influenced by these acidotic episodes, despite the fact that @entity1 with complications during their stay in the intensive care unit had lower perioperative @entity14243 values. The routine use of @entity14243 measurements during elective surgery of @entity1028 , therefore, is not justified.
