Abstract

Purpose

This study aims to determine whether perioperative treatment with dexmedetomidine (DEX) during laparoscopic radical prostatectomy (LRP) can provide a reno-protective effect.

Methods

This pilot study enrolled 89 patients between 60 and 79 years old, who underwent LRP. These patients were randomly allocated into two groups: group D (n = 44) and group C (n = 45). For patients in group D, 1 µg/kg of DEX was intravenously administered within 10 min, followed by 0.5 µg/kg/h of DEX infusion during the operation. This was stopped at 30 min before the end of surgery. For patients in group C, saline was administered at the same doses. The primary outcome was the incidence of acute kidney injury (AKI), and secondary outcomes included other postoperative variables.

Results

The incidence of AKI in group D and C was 4.5% and 13.3%, respectively (P > 0.05). Compared with group C, patients in group D had significantly lower urea nitrogen levels at 6 h after surgery, lower creatinine levels at 6 and 48 h after surgery, and significantly lower CysC levels at 48 h after surgery. A significant decrease in VAS scores for pain and postoperative nausea and vomiting (PONV) at the second and third day after surgery was observed in patients in group D when compared to patients in group C.

Conclusion

Intraoperative DEX does not reduce the incidence of AKI, but provides a potential reno-protective effect, and alleviates postoperative pain and PONV in patients undergoing LRP.
