This study evaluated the effectiveness of an ice pack applied for 20 minutes to alleviate perineal pain after spontaneous vaginal birth.
We conducted a randomized controlled trial at the Amparo Maternal Birth Center in São Paulo, Brazil. Study participants included 114 nulliparous women divided into 3 groups (n = 38 per group): experimental (ice packs on the perineum), placebo (water packs at set temperature), and control (no treatment).
A numerical scale (0 to 10) was used for pain assessment. A comparison of the average pain at the beginning and after 20 minutes showed a significant reduction of pain (P < .001) in the 3 groups, and the experimental group had a lower average score for pain compared with the control group (1.6 versus 3.3, P = .032).
The use of ice packs for 20 minutes was effective for perineal pain relief after vaginal birth.
本研究评估了在自然分娩后应用冰袋 20 分钟缓解会阴疼痛的效果。
我们在巴西圣保罗的 Amparo 产妇分娩中心进行了一项随机对照试验。研究参与者包括 114 名初产妇，分为 3 组（每组 38 名）：实验组（冰袋敷于会阴部）、安慰剂组（设定温度的水袋）和对照组（无治疗）。
使用数字量表（0 到 10）评估疼痛。比较开始时和 20 分钟后的平均疼痛，3 组的疼痛均显著减轻（P<0.001），实验组的疼痛平均评分低于对照组（1.6 对 3.3，P=0.032）。
冰袋使用 20 分钟可有效缓解阴道分娩后的会阴疼痛。
