Trial Summary

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. However, if you are on chronic narcotics for other reasons, you would not be eligible to participate.

What data supports the effectiveness of the treatment Intercostal Nerve Cryotherapy for postoperative pain?

Research shows that intercostal nerve cryotherapy can significantly reduce postoperative pain, as seen in patients undergoing thoracotomy (chest surgery) and aortic aneurysm repairs. Patients treated with this method experienced less pain and required fewer pain medications compared to those who received other treatments or no nerve block.12345

Is cryotherapy for postoperative pain generally safe for humans?

Cryotherapy for postoperative pain, specifically intercostal nerve cryotherapy, is generally considered safe. Some patients may experience numbness in the skin near the treatment area, but serious side effects are rare. There have been no reports of nerve inflammation or abnormal tissue growth, and only a few cases of minor lung issues.36789

How does cryotherapy differ from other treatments for postoperative pain?

Cryotherapy is unique because it involves freezing techniques to temporarily interrupt nerve function, providing pain relief without the use of drugs. It has been shown to reduce postoperative pain more effectively than local anesthetics and can decrease the need for opioids, ventilation days, and intensive care days in patients with rib fractures.234710

What is the purpose of this trial?

This is a research study designed to test whether a treatment called Intercostal Nerve Cryotherapy is an effective way to help control post-surgical pain for patients undergoing minimally invasive pulmonary resection.There are two treatment groups in this study, a cryotherapy group and control group. Cryotherapy is a method of controlling pain by freezing nerves between the ribs that would transmit pain impulses to the brain.

Eligibility Criteria

This trial is for adults over 18 who are having minimally invasive lung surgery (like VATS or robotic) and can communicate in English. They should be relatively active (performance status of 1 or 2), not have had previous chest surgery on the same side, no severe heart issues (ejection fraction above 40%), normal kidney function, not have advanced liver disease, not be on long-term narcotics, and able to consent.

Inclusion Criteria

I am scheduled for a minor lung surgery using VATS or robotic methods.
I can do light work but not heavy physical activities.

Exclusion Criteria

I have been diagnosed with fibromyalgia.
You are regularly taking strong pain medications for other health reasons.
Your creatinine level is higher than 1.5.

Interventions

  • Intercostal Nerve Cryotherapy
Trial Overview The study is testing Intercostal Nerve Cryotherapy—a pain control method that freezes nerves—to see if it's better than standard pain treatments after minimally invasive lung surgeries. Participants will either receive cryotherapy or the usual pain management as a control group.

Findings from Research

In a study of 24 patients, those who received intercostal block using cryotherapy experienced significantly less postoperative pain compared to those who received local anesthetics or no blockade.
The nerve function interruption caused by cryotherapy was temporary, lasting no more than 30 days, and there were no adverse side effects reported, indicating a safe and effective pain management option.
Cryoanalgesia for post-thoracotomy pain.Katz, J., Nelson, W., Forest, R., et al.[2019]
Ultrasound-guided percutaneous cryoneurolysis of the intercostal nerves was successfully used to treat a 40-year-old male with severe post-thoracotomy pain syndrome (PTPS) that had persisted for two years.
The treatment resulted in a 75% reduction in pain immediately after the procedure, with sustained 50% pain relief for eight weeks, suggesting that this method is a safe and effective option for managing chronic PTPS.

In a study of 144 patients undergoing thoracotomy, those who received cryoanalgesia for pain relief required significantly less narcotics and experienced lower pain scores compared to those who received traditional bupivacaine-adrenaline blockade.
Cryoanalgesia was found to be safe, with no late nerve complications reported, suggesting it could be recommended for routine use in thoracotomy procedures.
