Hypotension Prediction Effect on AKI

Effect of Use of Hypotension Prediction System in Prevention of Postoperative Acute Kidney Injury in Radical Cystectomy

It is a single-center randomized controlled trial that aims to figure out the effect of the hypotension prediction index (HPI) on the prevention of acute kidney injury (AKI) after radical cystectomy. The primary hypothesis is that HPI software guidance prevents postoperative AKI by reducing the duration and severity of intraoperative hypotension (IOH).

Inclusion Criteria:

• Age ≧ 19
• Patients undergoing radical cystectomy with neobladder reconstruction
• Patients undergoing radical cystectomy with ileal conduit urinary diversion

Exclusion Criteria:

• Unable to voluntarily give consent
• Unable to use both radial arteries due to such reasons: prior surgery on the radial artery, breast cancer history with axillary LN dissection, AV fistula for renal replacement therapy, or abnormal Allen's test.
