Enhanced recovery open radical prostatectomy: costs and length of hospital stay.

Purpose: To evaluate factors related to the length of hospital stay and costs in patients undergoing local multimodal anesthetic solution compared to neuraxial block, both in association with general anesthesia.

Methods: This is a retrospective cohort study of 77 consecutive patients submitted to open radical prostatectomies: 42 under general anesthesia plus neuraxial block, and 35 under enhanced recovery multimodal general anesthesia associated with preemptive target anesthetic solution (3 phases-P.T.A.S). Mann-Whitney, Chi-square, and Spearman correlation were applied with a 5% significance level.

Results: There were no statistically significant differences between the two groups. The cost was positively and significantly related to the pathological report (PR), anesthetic time, use of crystalloid, and total drain volume. Length of hospital stay was positively and significantly related to the use of crystalloids and total drain volume, with a strong correlation with the latter.

Conclusion: There was no statistically significant difference between the studied groups; however, there was a tendency to reduce the length of stay in the multimodal anesthetic solution group that may be better evidenced in studies with greater sampling power.
