We present a descriptive study based on the data from two clinical trials conducted at a maternity hospital in São Paulo, Brazil, in 2008 and 2009. This study aimed to describe perineal temperature after the application of an ice pack during the postpartum period. Three groups of 38 postpartum women (n=114 total) received an ice pack between 2 and 48 h after delivery. The results showed that after 10 minutes of cryotherapy, the mean perineal temperature varied between 13.3 degreeCand 15.3 degree"C, with a small reduction at the end of the 15- and 20-minute applications (2.4 degreeC and 2.7"C, respectively). Women who received cryotherapy for 10 minutes reported a cool sensation and pain relief; after a session of 15 or 20 minutes, the women reported anesthesia and numbness. In conclusion, an ice pack applied for 10 minutes reduced the perineal temperature to the recommended levels for analgesia (10-15 degreeC).
我们基于2008年和2009年在巴西圣保罗一家妇产医院进行的两项临床试验数据进行了一项描述性研究。本研究旨在描述产后使用冰袋后会阴部的温度。三组各38名产后妇女（共114名）在分娩后2至48小时接受了冰袋治疗。结果显示，冷冻疗法10分钟后，会阴部平均温度在13.3摄氏度至15.3摄氏度之间，在15分钟和20分钟治疗结束时略有下降（分别下降2.4摄氏度和2.7摄氏度）。接受10分钟冷冻疗法的妇女报告有凉爽感和疼痛缓解；在15分钟或20分钟的治疗后，妇女报告有麻木和麻醉感。总之，应用10分钟的冰袋可将会阴部温度降至推荐的镇痛水平（10至15摄氏度）。
