Summary

Acute renal injury (AKI) is a common complication after cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC), and is associated with worse outcomes. Available evidences show that maintaining intraoperative urine output ≥ 200 ml/h by fluid and furosemide administration may reduce the incidence of AKI in patients undergoing cardiopulmonary bypass. The investigators hypothesize that, for patients undergoing CRS-HIPEC, intraoperative urine-volume guided hydration may also reduce the incidence of postoperative AKI.

Detailed description

Acute renal injury (AKI) is a common complication after cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC), and is associated with worse outcomes. Studies showed that less intraoperative urine volume was associated with AKI. In studies of contrast-associated AKI, intraoperative and 4-h postoperative hydration and forced diuresis to achieve urine output ≥ 300 ml/h reduces the incidence of AKI by 44%. In patients undergoing cardiac surgery under cardiopulmonary bypass, maintaining intraoperative and 6-h postoperative urine output ≥200 ml/h by fluid and furosemide administration reduces the incidence of AKI by 52%. For patients with rhabdomyolysis, it is recommended to maintain urine output at approximately 3 ml/kg/h (200 ml/h) with volume supplementation. We suppose that forced diuresis with simultaneous hydration (balancing urine output with intravenous fluid infusion) may reduce AKI after CRS-HIPEC. The purpose of this randomised controlled trial is to investigate whether maintaining urine output at 200 ml/h (3 ml/kg/h) or higher by forced diuresis with simultaneous hydration can reduce the incidence of AKI after CRS-HIPEC.

• Postoperative Complications

Interventions

Type	Name	Description
PROCEDURE	Urine-guided hydration	The target is to maintain urine output at 200 ml/h (3 ml/kg/h) or higher by intravenous injection/infusion of furosemide throughout surgery. That is, a loading dose of 20 mg is injected at the beginning of surgery; if urine output does not reach the target value, furosemide will be continuously infused at 10 mg/h until the end of surgery, with a cumulative dose not exceeding 250 mg. Intravenous rehydration is performed to balance urine output and to maintain the SVV ≤10%.
PROCEDURE	Routine hydration	The target is to maintain urine output at 0.5 ml/kg/h or higher according to routine practice. That is, furosemide is only administered when clinically necessary or at discretion of responsible anesthesiologists; intravenous rehydration is performed to maintain the SVV ≤10%.
DRUG	Forced administration of furosemide	Forced administration of furosemide
DRUG	Routine administration of furosemide	Routine administration of furosemide
