NCT03234543

Brief Summary

This phase II randomized (1:1) controlled trial will examine the effects of remote ischemic conditioning (RIC) on the outcomes of major abdominal surgery. One hundred subjects will be enrolled at a single institution - University Hospital - Newark. The study population are patients undergoing major abdominal surgery (anticipated to be \>/= 2 hrs long with a hospital stay \>/= 2 days). Subjects in the treatment group will receive lower limb ischemic conditioning at 3 different time points: before surgery, POD 1 and POD 2. The primary outcome is the 30-day comprehensive complications index (CCI). Key secondary outcomes are changes in systemic inflammatory markers in peripheral blood and 30-day mortality.

Outcome Measures

Primary Outcomes (1)

  • Comprehensive Complication Index

    The CCI, a validated and scaled score of all surgical complications (range 0 \[no complications\] to 100 \[death\]) will be computed for each subject using the publically available website, http://www.assessurgery.com/.

    30 days after surgery

Secondary Outcomes (7)

  • Completion all three interventions

    Up to 3 days

  • Hospital days

    Up to 30 days

  • 30-day mortality

    Up to 30 days

  • Plasma complement levels (C2, C4b, C5, C5a, and C5b-9)

    Up to 3 days

  • Plasma cytokines levels (TNF-a, IL - 1, 6, 8 and 10)

    Up to 3 days

  • +2 more secondary outcomes

Study Arms (2)

Remote Ischemic Conditioning

EXPERIMENTAL

The RIC intervention consists of 5 minutes of inflation of a pneumatic tourniquet placed mid-thigh followed by 5 minutes of deflation, repeated for 3 cycles. The pressure used will be 250 mmHg for the pre-operative intervention. Subsequent tourniquet pressures will be 50 mmHg above the patient's systolic blood pressure.

Procedure: Remote ischemic conditioning

No Remote Ischemic Conditioning

SHAM COMPARATOR

The No RIC group will receive a sham intervention at all the same time points. The thigh tourniquet will be inflated to only 20 mmHg (to mask the intervention from the subject).

Procedure: No Remote ischemic conditioning

Interventions

Placement of blood pressure cuff to lower extremity in order to induce temporary and reversible ischemia.

Remote Ischemic Conditioning

Placement of blood pressure cuff to lower extremity with minimal inflation without inducing ischemia.

No Remote Ischemic Conditioning

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Adults (\> 18 years of age)
  • Both genders
  • Undergoing major abdominal surgery as above
  • Elective surgeries
  • Both outpatients and in-hospital patients
  • Post-op length of stay expected to be at least 2 days by the primary surgical service

You may not qualify if:

  • Subjects with lower extremity paralysis
  • Lower extremity amputees
  • Known, documented peripheral arterial disease
  • Body mass index \> 45
  • Pregnancy
  • Trauma patients
  • Organ transplant recipients
  • Prior major surgery during current hospitalization (for instance, a patient undergoing re-laparotomy for a complication from a previous procedure)
  • Patient taking sulfonylureas or nitrates prior to or during admission (listed in Appendix B)
  • a. These subjects are excluded because sulfonylureas are shown to abrogate the RIC effect whereas nitrates are shown to mimic the RIC effect in animal models.
  • Non-elective surgeries (urgent or emergent surgeries)
  • General surgical procedures with no planned intra-abdominal component

Masking Details
The study will be conducted in a double-masked fashion. Investigative team member/s that will carry out randomization and administer the intervention will not be involved in evaluation of clinical and laboratory outcomes. The primary surgical team, nurses, and any consulting services caring for the patient will be unaware of the group assignment. Other care providers will not be informed of the group assignment. Outcome assessors will not be involved in randomization and administration of the RIC intervention. Adequate steps are in place to mask the outcome assessors (clinical and laboratory) from knowing group assignment. Subjects will be masked from recognizing which group they are in in the following manner: a) Subjects will not be informed of the group assignment throughout their participation in the study; b) subjects randomized to No RIPC will have a tourniquet placed on the thigh and inflated.

Model Details: A prospective, randomized, double - masked clinical trial of RIC will be conducted in adult patients undergoing major abdominal surgery at University Hospital in Newark, NJ. Participants will be randomized into two groups: RIC and No RIC.
