Background: The purpose of this study was to investigate the efficacy of eyelid cooling to reduce postoperative pain, edema, erythema, and hematoma after upper blepharoplasty.
背景：本研究的目的是調查眼瞼冷卻對雙眼皮術後減少疼痛，水腫，紅斑和血腫的效果。
Methods: After bilateral upper blepharoplasty in 38 consecutive patients, one eyelid per patient was randomized for cooling with an ice pack, and the other eyelid was left uncooled. Pain was scored by the patients using a visual analogue scale (0 to 10) 1 hour and 1 day after surgery. Degree of edema, erythema, and hematoma were scored by the patients on a four-point rating scale (no, minimal, moderate, or severe) 1 hour, 1 day, 1 week, and 2 months after surgery. Light photography was obtained 1 week after surgery for scoring the degree of bruising on a four-point rating scale by a blinded observer.
方法：在38例患者雙側雙眼皮手術後，每患者的一邊眼皮是用冰袋冷敷，另一邊眼皮不冷敷。疼痛是以視覺模擬評分（0〜10）術後1小時及術後1天。水腫，紅斑和血腫的程度是由患者上的四點量表得分（無，最小，中度，或重度）術後1小時，1天，1週，及術後2個月。術後1週進行攝影紀錄青紫的程度。
Results: Pain did not differ between cooled and uncooled eyelids on the day of surgery. However, pain in cooled eyelids was significantly lower 1 day after surgery (p = 0.046), yet absolute pain scores were low (median, 0 and 0.5, on a scale of 10). Edema, erythema, or hematoma did not differ between cooled and uncooled eyelids on any of the time points studied.
結果：痛在手術當天在冷敷，未冷敷的眼皮之間沒有差異。但是術後一天疼痛在冷敷眼皮明顯較低（P = 0.046）。水腫，紅斑，或血腫在冷敷和未冷敷的眼皮之間沒有差別。
Conclusions: Cooling of eyelids after upper blepharoplasty does not reduce edema, erythema, or hematoma of the eyelids, but reduces pain 1 day after surgery. However, because the degree of pain seems clinically irrelevant and because the majority of patients indicate that they have no preference for cooling over noncooling, eyelid cooling after upper blepharoplasty as a rule of thumb can be abandoned.
結論：上眼皮手術後的冷敷不能減少水腫，紅眼球，或血腫，但減輕疼痛1天。然而多數患者表示，他們沒有覺得冷敷較好，所以上眼皮手術後的冷敷可以被放棄。
