Objective: To evaluate the short-term efficacy and safety of cold compression therapy (CCT) relative to a soft padded bandage (SPB) in dogs undergoing surgery to manage cranial cruciate ligament injury.

Methods:Dogs were randomized into groups that received CCT or SPB after surgery. Weight bearing was measured using a weight distribution platform before and the day after surgery. Stifle joint flexion and extension were measured using a goniometer before and the day after surgery. Rectal temperatures were measured every 15 min for 2 h after surgery and the morning after surgery. Mechanical nociceptive thresholds (MNT) were measured using an algometer the day after surgery. Findings in both groups were compared using a mixed model ANOVA.

Results:20 dogs were enrolled: 10 in the CCT and 10 in the SPB group. Dogs undergoing CCT had more stifle joint flexion (P = 0.008) and weight bearing (P < 0.001) after surgery than dogs with SPB. MNT after surgery correlated statistically with stifle joint flexion after surgery (r = −0.315, P = 0.014), extension after surgery (r = 0.310, P = 0.016), and weight bearing after surgery (r = 0.314, P = 0.003). Return to normothermia was delayed in the CCT group, with temperatures ~0.5°C (1.0°F) lower 105 (P = 0.018) and 120 min (P = 0.013) after surgery.

Conclusion:Relative to bandaging, CCT had a positive short-term impact on stifle flexion and weight bearing. CCT delayed warming after surgery but dogs were only mildly hypothermic [0.5°C [1.0°F]].

在窒息关节手术后,冷冻疗法可改善肢体的使用,但可延迟正常体温。

目的: 评估冷压疗法(CCT)相对于软垫绷带(SPB)在接受手术处理颅骨十字韧带损伤的犬中的短期疗效和安全性。

方法:手术后将狗随机分为接受CCT或SPB的组。在手术之前和之后的一天使用体重分配平台测量承重。术前和术后用测角仪测量关节的屈伸度。手术后2小时和手术后早晨每15分钟测量一次直肠温度。手术后第二天使用血压计测量机械伤害阈值(MNT)。使用混合模型方差分析比较两组的发现。

结果:招募了20条狗:CCT组10条,SPB组10条。接受CCT的狗的关节屈曲度更高(P = 0.008)和承重(P<0.001)手术后比SPB犬高。术后MNT与术后膝关节屈曲呈统计学相关性([R = −0.315, P = 0.014),手术后延长([R = 0.310, P = 0.016),并且手术后负重([R = 0.314, P= 0.003)。CCT组恢复正常体温延迟,温度低约0.5°C(1.0°F)105(P = 0.018)和120分钟(P = 0.013)。

结论:相对于包扎,CCT对窒息弯曲和负重有积极的短期影响。CCT延迟了手术后的升温,但是犬只略有体温过低[0.5°C [1.0°F]]。
