Cryoanalgesia (the use of cold to provide anesthesia or analgesia) is the oldest anesthetic and analgesic still in current clinical use. Its intraoperative use in providing postoperative analgesia for acute thoracic pain problems via an open thoracotomy is well described. The long-term efficacy of cryoanalgesia for the management of chronic thoracic pain due to intercostal neuralgia is less clear. We retrospectively examined the medical records of patients who received percutaneous cryoanalgesia following successful intercostal nerve blockade for chronic chest pain. Sixty percent of the patients (N = 43) reported significant pain relief immediately following their procedure. Three months following cryoanalgesia, 50% continued to report significant pain relief. There were no reports of neuritis or neuroma formation and only three patients had a pneumothorax. This work provides evidence that cryoanalgesia is a safe and efficacious method of providing analgesia for chronic thoracic pain due to intercostal neuralgia.
冷冻镇痛法（使用低温来提供麻醉或镇痛）是目前仍在临床使用的最古老的麻醉和镇痛方法。其在术中通过开胸手术为急性胸痛问题提供术后镇痛的应用已有详尽描述。冷冻镇痛法用于治疗因肋间神经痛引起的慢性胸痛的长期疗效尚不太明确。我们回顾性检查了因慢性胸痛在肋间神经阻滞成功后接受经皮冷冻镇痛的患者的病历。60%的患者（N = 43）在治疗后立即报告疼痛显著缓解。冷冻镇痛三个月后，50%的患者继续报告疼痛显著缓解。没有神经炎或神经瘤形成的报告，只有三名患者发生气胸。这项研究提供了证据，证明冷冻镇痛法是一种为因肋间神经痛引起的慢性胸痛提供镇痛的安全有效的方法。
