Perineal analgesia with an ice pack after spontaneous vaginal birth: a randomized controlled trial.

Introduction: This study evaluated the effectiveness of an ice pack applied for 20 minutes to alleviate perineal pain after spontaneous vaginal birth.

Methods: 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).
