Hyperbaric gaseous cryotherapy (HGC) is a type of cryotherapy used in human medicine for rehabilitation after orthopedic surgeries. Because HGC is known to reduce acute or chronic pain, research is needed to prove its effectiveness in veterinary medicine.
To compare the effects of HGC between the HGC treatment group and the nontreatment (NT) group on postoperative swelling, range of motion, lameness score, postoperative pain, and kinetic measurements after stifle joint surgery in dogs.
Dogs were randomized in an HGC group or NT groups. In the HGC group, HGC was applied once a day for a total of 2 days after surgery. All parameters were measured postoperatively and at 1, 2, 10, and 28 days after surgery.
Twenty dogs were enrolled: 10 in the HGC group and 10 in the NT group. Soft tissue swelling was not significantly different between groups at any time point. In the HGC group, pain scores decreased significantly 24 h after surgery and 48 h after surgery. Dogs in the HGC group showed a significantly decreased lameness and improvement for all kinetic measurements beginning 48 h after surgery. In addition, the HGC group indicated a significant increase in range of motion as compared with the NT group at 28 days after surgery.
HGC plays a powerful role in decreasing initial postoperative pain. Furthermore, the improvement in pain affects the use of the operated limb, and the continued use of the limb eventually assists in the quick recovery of normal function.
高压气体冷冻疗法（HGC）是一种在人体医学中用于骨科手术后康复的冷冻疗法。由于 HGC 已知可减轻急性或慢性疼痛，因此需要研究证明其在兽医中的有效性。
比较 HGC 治疗组与非治疗（NT）组在犬膝关节手术后肿胀、运动范围、跛行评分、术后疼痛和运动学测量方面的 HGC 治疗效果。
将犬随机分为 HGC 组或 NT 组。在 HGC 组中，手术后每天接受 HGC 治疗，共 2 天。所有参数均在术后以及术后第 1、2、10 和 28 天进行测量。
共纳入 20 只犬：HGC 组 10 只，NT 组 10 只。在任何时间点，两组的软组织肿胀均无显著差异。在 HGC 组中，术后 24 小时和 48 小时疼痛评分显著降低。HGC 组从术后 48 小时开始，跛行评分明显降低，所有运动学测量均得到改善。此外，HGC 组在术后 28 天与 NT 组相比，运动范围显著增加。
HGC 在减轻初始术后疼痛方面发挥了强大作用。此外，疼痛的改善影响了患肢的使用，并且持续使用患肢最终有助于快速恢复正常功能。
