The effects of acute hypervolemic hemodilution and conventional infusion in laparoscopic radical prostatectomy patients.

Objective: To compare the effect of acute hypervolemic hemodilution and conventional infusion in prostate cancer patients undergoing laparoscopic radical prostatectomies.

Methods: A total of 87 patients with prostate cancer who underwent laparoscopic radical prostatectomies in our hospital were retrospectively analyzed. The patients were randomly divided into a control group (the CNG, n=43, conventional infusion) and an observation group (the OG, n=44, acute hypervolemic hemodilution). Blood gas analyses were performed at different time points, and the patients' cognitive dysfunction was evaluated.

Results: The intraoperative blood transfusion rates of the OG and the CNG were 11.36% and 30.23%. The average intraoperative blood transfusions in the OG and the CNG were (315.46±24.49) ml and (486.95±42.17) ml ( < 0.05). The CVP and JVP levels in the OG and the CNG at T2 and T3 were significantly higher than the levels at T0 ( < 0.05). The Hb levels of the CNG at T3 and T4 were lower than they were at T0 ( < 0.05), and the Hb level in the OG at T4 was lower than it was at T1 ( < 0.05). The Hb levels in the CNG at T3 and T4 were lower than they were at T1 ( < 0.05), and the Hb levels in the OG at T1 and T2 were lower than they were in the CNG ( < 0.05). The MMSE cognitive function scores were lower than the scores recorded on the day before the operations ( < 0.05).

Conclusion: Acute hypervolemic hemodilution in laparoscopic radical prostatectomy patients can maintain their hemodynamics in a stable state, help reduce blood transfusion, improve the oxygen supply to the brain tissue to maintain the supply and demand balance, and reduce the impact on the patients' cognitive function.
