Cryo NerVe Block Extremity AmputatioN RegIStry for Post Operative and pHantom Limb Pain

The goal of this Registry is to see how the device is used when freezing nerves during an amputation procedure.

Cryo Nerve Block Trial

Background: Minimally invasive lung surgery, such as video-assisted thoracoscopic surgery (VATS) or robot-assisted thoracoscopic surgery (RATS), has become more common for lung resections because it leads to faster recovery, less pain, and shorter hospital stays. However, pain after surgery remains a major issue. Current guidelines suggest using a combination of pain management strategies to reduce the use of opioids and their side effects. Intercostal cryo-analgesia (ICCA), a technique that uses cold to reduce nerve activity, may help lower pain and opioid use after surgery. However, there is limited research on ICCA, with most studies having small sample sizes and lacking randomized controlled trials. More research is needed to compare ICCA with standard pain management in patients undergoing minimally invasive lung surgery. Objective: The goal of this study is to determine whether ICCA improves recovery compared to standard pain management after minimally invasive lung surgery. The investigators aim to measure recovery time and quality using the Quality of Recovery-15 (QoR-15) questionnaire. The investigators expect that ICCA will result in better recovery, less pain, reduced opioid use, and shorter hospital stays, without increasing the risk of nerve damage or other complications. Study Design: This will be a single-center, blinded, randomized controlled trial, along with an observational registry. Study Population: The study will include adults who are undergoing elective minimally invasive lung resections. Intervention: Patients in the intervention group will receive ICCA in addition to standard pain management after surgery. ICCA will be administered by the surgeon before closing the wound, targeting the intercostal nerves between ribs 3 and 7. Main Study Parameters/Endpoints: The primary outcome will be recovery time, measured using the QoR-15 questionnaire. The QoR-15 assesses overall recovery after surgery across several domains, with a score of 118 or higher indicating good recovery. The questionnaire is a reliable and valid tool for measuring postoperative recovery. Risks and Benefits: This trial will examine the effects of adding ICCA to the standard pain management protocol. Potential risks include numbness or nerve damage, neuropathic pain (pain caused by nerve injury), or complications such as bleeding (hematoma) or lung collapse (pneumothorax) at the treatment site. The potential benefits of ICCA include improved recovery, reduced opioid use, less pain, shorter hospital stays, and fewer respiratory complications after surgery.

Long Term Safety of Preoperative Percutaneous Intercostal Cryoneurolysis

Follow up of patients who underwent percutaneous cryoneurolysis for pectus excavatum repair (the Nuss procedure) pain management

Phrenic Infiltration as Cryoanalgesia Adjuvant for Early Postoperative Pain Following the Nuss Procedure

The goal of this observational ambispective study is to compare the effectiveness of two pain management strategies in pediatric patients undergoing the Nuss procedure for pectus excavatum. The main questions it aims to answer are: Does the addition of phrenic Infiltration as Cryo Adjuvant (PhICA) to earlier percutaneous intercostal cryoanalgesia (EPIC) reduce postoperative pain scores compared to EPIC alone? Does the combined EPIC + PhICA technique reduce the need for rescue tramadol compared to EPIC alone? Do the two approaches differ in: length of hospital stay, time to transition to oral therapy, and time to mobilization? Are there any side effects Researchers will compare patients who received EPIC alone to patients who received EPIC + PhICA to see if the combined technique provides superior pain control. Participants: Received either EPIC alone or EPIC combined with PhICA as part of their surgical anesthesia plan Had pain levels assessed using the Numeric Rating Scale (NRS) at regular postoperative intervals Were monitored for rescue tramadol requirements, medicaments taken, length of hospital stay, and mobilization timing Were monitored for any technique-related complication

Correlation Between Diagnostic Nerve Block Response and Cryoneurolysis Outcome in Chronic Musculoskeletal Disorders

The clinical study is titled the CRYONIC PROTOCOL, which stands for Cryotherapy for Neurolysis In Chronic Pain. It is structured as a prospective, multi-cohort observational study. Purpose of the Study: The overarching purpose of the CRYONIC PROTOCOL study is to assess the Correlation Between Diagnostic Nerve Block Response and Cryoneurolysis Outcome in Chronic Musculoskeletal Disorders. The study focuses on evaluating the effectiveness of ultrasound-guided peripheral nerve cryoneurolysis, a minimally invasive technique that uses extreme cold to induce temporary nerve blocks, for patients with treatment-resistant chronic musculoskeletal pain. The study also seeks to determine if cryoneurolysis itself leads to meaningful improvements in both pain intensity and functional ability in the included patient cohorts.
