Ice-pack is widely used for alleviating postpartum perineal pain sustained after birth related perineal trauma. However, it lacks robust evidence on timing and frequency of applications, to ensure the effective and safe use of this therapy.
To evaluate if a 10min ice-pack application relieved postpartum perineal pain and if the analgesic effect was maintained for up to 2h.
A randomised controlled trial conducted from December 2012 to February 2013 with 69 primiparous women ≥18 years old, 6-24h postpartum, with perineal pain ≥3, who had not received anti-inflammatory medication or analgesics after childbirth, who were randomised to a single ice-pack application on the perineum for 10min or standard care. The primary and secondary outcomes were a reduction ≥30% in perineal pain intensity, immediately after the application and the maintenance of the analgesic effect for up to 2h, respectively.
Immediately post-intervention, the proportion of women whose perineal pain decreased ≥30% was significantly higher in the experimental group. Within 2h, there was no significant difference in the pain levels in both groups. Within 2h, for 61.9% and 89.3% of women in the experimental and control group, respectively, the perineal pain levels remained unchanged. For the remaining participants, perineal pain was increasing after an average time of 1h 45min and 1h 56min for the experimental and control groups, respectively.
By applying an ice-pack for 10min to the perineum, effective pain relief is achieved, that is maintained for between 1h 45min and 2h.
冰袋广泛应用于缓解分娩相关会阴创伤后产后会阴疼痛。然而，在确保这种治疗方法的有效性和安全性方面，冰袋应用的时间和频率缺乏有力的证据。
评估 10 分钟冰袋应用是否能缓解产后会阴疼痛，以及镇痛效果是否能维持长达 2 小时。
这是一项随机对照试验，于 2012 年 12 月至 2013 年 2 月进行，纳入 69 名年龄≥18 岁、产后 6-24 小时、会阴疼痛≥3 分、产后未接受抗炎药物或镇痛药治疗的初产妇，将其随机分为会阴单次冰敷 10 分钟或标准护理。主要和次要结局分别为应用后即刻会阴疼痛强度降低≥30%和镇痛效果维持长达 2 小时。
干预后即刻，实验组中会阴疼痛减轻≥30%的女性比例明显更高。在 2 小时内，两组的疼痛水平没有显著差异。在 2 小时内，实验组和对照组分别有 61.9%和 89.3%的女性会阴疼痛水平保持不变。对于其余参与者，实验组和对照组的会阴疼痛在平均 1 小时 45 分钟和 1 小时 56 分钟后分别呈上升趋势。
会阴冰敷 10 分钟可有效缓解疼痛，并能维持 1 小时 45 分钟至 2 小时。
