Clinical Trial Summary

Our primary aim is to investigate whether perioperative remote ischemic conditioning (PRIC) as an adjunctive treatment can improve postoperative recovery in patients undergoing hepatectomy as an adjunct to standard treatment.

Description:

Remote Ischemic Conditioning (RIC) can be applied as repeated short-lasting ischemia in a distant tissue that results in protection against subsequent long-lasting ischemic injury in the target organ. This protection can be applied prior to or during a prolonged ischemic event as remote ischemic pre-conditioning (RIPreC) and per-conditioning (RIPerC), respectively, or immediate after reperfusion as remote ischemic post-conditioning (RIPostC).

RIC is a non-pharmacologic and non-invasive treatment without noticeable discomfort, commonly achieved by inflation of a blood pressure cuff to induce 5-minute cycles of limb ischemia alternating with 5 minutes of reperfusion. However, whether perioperative remote ischemic conditioning (PRIC) can improve postoperative recovery in patients undergoing hepatectomy has never been investigated in a randomized controlled trial.

Intervention

Device:
• Sham-Remote Ischemic Conditioning
Sham-Remote Ischemic Conditioning (at the time points of 30 min before anesthesia, 30 min after surgery, the morning of the postoperative day 1, the afternoon of the postoperative day 1, the morning of the postoperative day 2, the afternoon of the postoperative day 2): Three cycles (30 minutes), each consisting of five minutes of cuff inflation followed by five minutes with a deflated cuff, but the cuff pressure will be 0 mmHg.
• Remote Ischemic Conditioning Once Daily
Remote Ischemic Conditioning (at the time points of 30 min before anesthesia, the morning of the postoperative day 1, the morning of the postoperative day 2): Three cycles (30 minutes), each consisting of five minutes of cuff inflation followed by five minutes with a deflated cuff. The cuff pressure will be 200 mmHg. Sham-Remote Ischemic Conditioning (at the time points of 30 min after surgery, the afternoon of the postoperative day 1, the afternoon of the postoperative day 2): Three cycles (30 minutes), each consisting of five minutes of cuff inflation followed by five minutes with a deflated cuff, but the cuff pressure will be 0 mmHg.
• Remote Ischemic Conditioning Twice Daily
Remote Ischemic Conditioning (at the time points of 30 min before anesthesia, 30 min after surgery, the morning of the postoperative day 1, the afternoon of the postoperative day 1, the morning of the postoperative day 2, the afternoon of the postoperative day 2): Three cycles (30 minutes), each consisting of five minutes of cuff inflation followed by five minutes with a deflated cuff. The cuff pressure will be 200 mmHg.
