早期持续冰敷对上颌截骨正颌术后患者的影响

Effects of early continuous cooling in patients after maxillary osteotomy orthognathic surgery

目的探讨基于温度控制的持续冰敷对上颌Le FortⅠ型截骨正颌手术后患者早期上颌肿胀、出血、疼痛、舒适度及非冻结性损伤发生率的影响。方法将63例上颌Le FortⅠ型截骨正颌手术患者随机分为观察组(33例)和对照组(30例),术后6 h内分别进行基于温度控制的持续冰敷(观察组)和间断冰敷(对照组)。结果观察组冰敷前后肿胀进展程度显著小于对照组,冰敷期间的舒适度得分显著高于对照组(均P<0.05);两组冰敷期间使用止血药量、镇痛药量和非冻结性损伤发生率差异无统计学意义(均P>0.05)。结论基于温度控制的持续冰敷能有效缓解上颌Le FortⅠ型截骨正颌手术后患者早期上颌肿胀,增加患者舒适度,不会导致患者皮肤损伤。

Objective To explore the effects of temperature-controlled continuous cooling on early maxillary swelling,bleeding,pain,comfort and the incidence of non-freezing injury in patients after maxillary Le FortⅠosteotomy orthognathic surgery.Methods Sixty-three patients after maxillary Le FortⅠosteotomy orthognathic surgery were randomized into an experimental group(n=33)and a control group(n=30),who were applied temperature-controlled continuous cooling and intermittent cooling respectively within 6 hours after the surgery.Results The swelling progression before and after cooling in the experimental group was significantly less than that in the control group,and the comfort score during cooling was significantly higher than that in the control group(P<0.05 for both),there were no significant differences in the dosage of hemostatic drugs and analgesics,and the incidence of non-freezing injuries between the two groups(P>0.05 for all).Conclusion The temperature-controlled continuous cooling can effectively relieve early maxillary swelling and increase the comfort of patients after maxillary Le FortⅠosteotomy orthognathic surgery,and it doesn′t cause skin injury.
