Randomized Controlled Trial Clinical Trial
[Renal protection during surgical procedures on the infrarenal aorta].
Despite the progress in surgical and anaesthetic management, decreased renal function is still observed after abdominal infrarenal aortic surgery and remains an important problem in postoperative period. Although data regarding the efficacy of perioperative renal protection are conflicting, it is widely believed that renal protection before aortic cross-clamping is beneficial and therefore is commonly used. The aim of this study was to evaluate the impact of renal protection in patients undergoing elective infrarenal aortic surgery (1ARS). ⋯ Patients in groups A and B were similar regarding the age (64.32 vs. 62.00), sex (males 35, females vs. males 34, females 6) and preoperative diseases. (Tab. 2) No difference was found between groups regarding any of the parameters (BUN, serum creatinine, electrolytes, volume load, creatinine and free-water clearance, haemodynamic parameters, plasma and urine osmolality). Urinary output was higher in group B during and 2 hours after ACC. (Graph 1.) ACC time was similar in two groups (24.1 min vs 24.5 min). (Graph. 2) Only one patient in group B revealed transitory renal insufficiency, not requiring special treatment. These data indicate that renal protection did not influence renal function. Short ACC time may have impact on the obtained results. Our results suggest that renal protection should not be considered as mandatory for elective infrarenal aortic surgery. Because of the short ACC time observed in this study (in comparison to other studies), further studies of renal protection in patients with longer ACC time are needed.
