The Effect of Intermittent Cryotherapy Exposure on Patients' Quality of Recovery After Surgery (ICE)

January 8, 2026 updated by: Dr. Paul Karanicolas, Sunnybrook Health Sciences Centre

The Effect of Intermittent Cryotherapy Exposure (ICE) on Patients' Quality of Recovery After Surgery: A Vanguard Randomized Control Trial

"Cryotherapy", or cold therapy, can include the use of gel packs, ice bags, ice baths, whole body chambers, and cold aerosol sprays. It is a popular non-drug treatment that can be used after a surgical operation, along with medication such as narcotics and anti-inflammatories for pain management. The application of ice packs on areas of injury has been used for many decades, as they can decrease both inflammation and pain. Other possible benefits include reduced blood flow, swelling, and tissue damage as well as muscle spasms. While there is some evidence to suggest that the use of ice packs is beneficial, this has not yet been implemented into practice, nor do any guidelines recommend the use of ice packs for pain management in surgical patients. In this trial, adult patients undergoing scheduled thoracoabdominal or groin surgery will be randomly assigned to apply ice packs over the largest closed surgical incision every 4 hours, at minimum, for 72 hours (while the patient is awake), along with standard of care, or to receive standard of care only. This trial will be conducted under the IMPACTS (Innovative, Multicentre, Patient-centred Approach to Clinical Trials in Surgery) program umbrella and will follow IMPACTS methodology. For the Vanguard trial, the aim is to determine the feasibility of conducting a definitive trial. Future outcomes of interest are quality of patient recovery, pain, length of hospital stay and medication use.

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Background/rationale: To date, there is some evidence to suggest a benefit of cryotherapy application over closed post-operative incisions, however, this has not yet been implemented into practice. Furthermore, there are no clinical practice guidelines that recommend the application of cryotherapy for adjuvant pain management. Relevant randomized controlled trials (RCTs) in abdominal surgery demonstrate a possible advantage of cryotherapy application, when compared to no cryotherapy application. However, those RCTs were small and were restricted to gynecology procedures or emergent procedures. Therefore, the investigators aim to address this knowledge gap by assessing the benefit of applying cryotherapy post-operatively (along with standard of care approaches), compared to no cryotherapy, (i.e., standard of care, only) over closed incisions, across broad surgical specialties and procedures, to improve the quality of patient recovery in adult patients.

Objectives: Before embarking on a definitive RCT, this pilot trial has five specific feasibility objectives:

  1. To assess the investigators' ability to accrue patients using the IMPACTS Program design platform at multiple institutions, over the course of one year.
  2. To assess the investigators' ability to adaptively randomize patients and deliver the randomized assignment using the IMPACTS Program design platform, over the course of one year.
  3. To assess the investigators' ability to collect complete data directly from participants (patients and clinicians) on: narcotics use and surgical site infections over the course of one year.
  4. To examine the investigators' ability to carry out data linkages using the IMPACTS Program design platform over the course of one year.
  5. To estimate the change in quality of recovery to inform the sample size calculation for the definitive trial.

Study design: This is a multicentre, pragmatic, open label, two-arm parallel-group Vanguard feasibility randomized controlled trial. Patients will be randomized to cryotherapy application or no cryotherapy application. If feasibility is demonstrated during the pilot trial, the investigators will plan to conduct a definitive trial. If there are only minimal changes to the protocol, the investigators will include data from the pilot phase into the definitive trial analysis (i.e. a Vanguard design).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
