Preoperative (Pre-amputation) Cryoanalgesia to Improve Post-amputation

Status Recruiting

Clinical Trial Summary

Investigators will evaluate preamputation cryoanalgesia on pain, mobility, opioid use and general physical and emotional disability using a pilot randomized trial design, to explore the amount and variability of improvement on those outcomes and to investigate the potentiality of conducting a future larger randomized controlled trial, which the investigators will assess quantitatively the benefits of cryoanalgesia.

Clinical Trial Description

Primary Aim: To determine preoperative cryoneurolysis improves phantom limb pain compared with no cryoneurolysis. Estimate the standard deviation of phantom limb pain score at baseline and post-treatment (Day 0), Days 1 and 2; Weeks 1, 2, 3, and Months 1, 2 and 3. The investigators will consider using the upper limit of the 75% confidence interval to plan the sample size of future larger trial. Hypothesis 1: Preoperative cryoneurolysis reduces phantom limb pain over 3 month after surgical leg amputation compared with no cryoneurolysis. Secondary Aim 1: To determine if preoperative cryoneurolysis improves mobility after lower limb amputation compared with no cryoneurolysis. Hypothesis 1: Preoperative cryoneurolysis improves mobilization (as measured with accelerometer) over 3 the month after surgical leg amputation compared with no cryoneurolysis. Secondary Aim 2: To determine if preoperative cryoneurolysis improves general physical and emotional disability after lower limb amputation compared with no cryoneurolysis. Hypothesis 2: Preoperative cryoneurolysis reduces general physical and emotional disability (as measured with the World Health Organization Disability Assessment) over the 3 month after surgical leg amputation compared with no cryoneurolysis. Secondary Aim 3: To determine if preoperative cryoneurolysis decreases opioid use after lower limb amputation compared with no cryoneurolysis. Hypothesis 3: Preoperative cryoneurolysis reduces opioid consumption over the 3 month after surgical leg amputation compared with no cryoneurolysis. Exploratory Aims: Hypothesis 1: Preoperative cryoneurolysis reduces residual limb pain over the 3 months after surgical leg amputation compared with no cryoneurolysis. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
