Official title
Cryoanalgesia to Prevent Acute and Chronic Pain Following Surgery
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The ultimate objective of the proposed line of research is to determine if cryoanalgesia is an effective adjunctive treatment for pain in the period immediately following various painful surgical procedures; and, if this analgesic modality decreases the risk of persistent postoperative pain, or "chronic" pain. The objective of the proposed pilot study is to optimize the protocol and collect data to power subsequent, definitive clinical trials. Specific Aim 1: To determine if, compared with current and customary analgesia, the addition of cryoanalgesia decreases the incidence and severity of post-surgical pain. Hypothesis 1a (primary): The severity of surgically-related pain will be significantly decreased on postoperative day 2 with the addition of cryoanalgesia as compared with patients receiving solely standard-of-care treatment. Hypothesis 1b: The incidence of chronic pain will be significantly decreased one year following surgery with the addition of cryoanalgesia as compared with patients receiving solely standard-of-care treatment. Hypothesis 1c: The severity of chronic pain will be significantly decreased one year following surgery with the addition of cryoanalgesia as compared with patients receiving solely standard-of-care treatment. Specific Aim 2: To determine if, compared with current and customary analgesia, the addition of cryoanalgesia improves postoperative functioning. Hypothesis 2a: Following primary unilateral knee and shoulder arthroplasty as well as rotator cuff repair, joint range of motion will be significantly increased within the year following surgery with the addition of cryoanalgesia as compared with patients receiving solely standard-of-care treatment. Hypothesis 2b: Following video-assisted thoracoscopic surgery, inspiratory spirometry will be improved within the month following surgery with the addition of cryoanalgesia as compared with patients receiving solely standard-of-care treatment.
