## 문제

Situation: A 22-year-old primipara gave birth vaginally to a healthy term newborn at a lying-in clinic, and her episiotomy was repaired. She plans to breastfeed exclusively, and the nurse follows her through the first days after birth.

Eight hours after birth, the area around the repaired episiotomy is swollen and painful. There is no hematoma, and the edges are well approximated. Which comfort measure should the nurse use now?

## 보기

1. Apply a warm compress over the perineum
2. Apply wrapped ice to the perineum **✔ 정답**
3. Seat her on a soft ring-shaped cushion
4. Start warm sitz baths three times a day

**정답: 2**

## 해설

During the first 24 hours after birth, cold reduces perineal edema and pain by causing vasoconstriction. Warm sitz baths are started after the first 24 hours to promote circulation and healing. Sitting on firm surfaces while tightening the buttocks is advised rather than ring cushions.

## 심화 해설

The nurse should apply wrapped ice to the perineum during the first 24 hours after birth.

Why cold is the correct choice in the first 24 hours

The immediate postpartum period is characterized by tissue trauma, capillary leakage, and an acute inflammatory response at the episiotomy site. Swelling and pain at 8 hours after repair reflect this early inflammatory phase. Cold application produces vasoconstriction, which reduces local blood flow, limits fluid extravasation into the interstitial space, and slows the metabolic rate of injured tissue. The result is decreased edema formation and a dampening of nociceptor activation, which together reduce both swelling and pain perception [1][2].

Cold therapy is most effective when initiated early, before edema has fully developed, and is the standard comfort measure for perineal trauma during the first 24 hours postpartum. In a retrospective cohort study of primiparous women, immediate perineal cryotherapy during labor was associated with reduced early postpartum pain and perineal edema compared with no cryotherapy, supporting the early use of cold in this window [2].

Timing matters: cold first, then warmth

The choice between cold and heat depends on the phase of tissue healing. Cold is appropriate for the acute, inflammatory phase when vasoconstriction is desired. Warmth is introduced later, after the acute swelling has subsided, to promote vasodilation, increased circulation, and tissue repair.

| Intervention | Onset after birth | Primary effect | Rationale |
| --- | --- | --- | --- |
| Wrapped ice or cold pack | 0–24 hours | Vasoconstriction, reduced edema and pain | Limits capillary leakage during acute inflammatory phase [1][2] |
| Warm sitz bath | After 24 hours | Vasodilation, increased circulation, healing | Promotes tissue repair once acute edema has resolved |

Watch out! Applying heat too early can worsen swelling by increasing blood flow to already engorged, injured tissue. Warm sitz baths are started only after the first 24 hours, not during the acute edematous phase.

Why the other options are not appropriate now

A warm compress (option 1) would cause vasodilation and increase local blood flow, potentially aggravating edema at 8 hours postpartum. Warm sitz baths (option 4) are similarly contraindicated during the first 24 hours for the same reason.

A soft ring-shaped cushion (option 3) may seem intuitive for perineal comfort, but it can actually impair venous return from the perineal area and increase local venous congestion and swelling. Sitting on firm surfaces while tightening the buttocks before sitting is preferred over ring cushions because it supports the perineum without creating a pressure gradient that promotes edema.

Practical application for the nurse

When applying cold to the perineum, the nurse should wrap the ice pack or cold gel pack in a clean cloth or disposable cover to protect the skin from direct thermal injury. Application is typically intermittent, such as 15 to 20 minutes on and 15 to 20 minutes off, to allow tissue rewarming and prevent excessive vasoconstriction or cold-induced tissue damage. The nurse should also assess the perineum regularly for signs of hematoma, excessive bleeding, or wound separation, and document pain level, edema, and the patient’s response to the intervention.

Key point! The first 24 hours after birth is the cold therapy window. After that, warmth is introduced to support healing. The nurse’s choice of comfort measure must match the phase of tissue recovery.References (research sources)

## 임상 시나리오

Perineal Cold Therapy TimingFirst 24 hours after birth
During the first 24 hours postpartum, apply wrapped ice to the perineum to reduce edema and pain through vasoconstriction.

Cold is most effective when started early, before edema fully develops. Use a cloth barrier between ice and skin to prevent tissue injury.

CautionDo not use warm compresses or sitz baths until after the first 24 hours. Avoid ring-shaped cushions; advise sitting on firm surfaces while tightening the buttocks.

## 핵심 개념

- **Vasoconstriction** — Narrowing of blood vessels that reduces local blood flow, limiting edema formation and pain during acute inflammation.
- **Episiotomy** — Surgical incision of the perineum during childbirth to widen the vaginal opening, requiring postpartum comfort measures.
- **Acute inflammatory phase** — Early tissue response to injury characterized by swelling, capillary leakage, and pain, typically the first 24 hours.
- **Sitz bath** — Warm water immersion of the perineal area used after 24 hours postpartum to promote circulation and healing.
- **Cryotherapy** — Therapeutic use of cold to reduce pain, edema, and metabolic demand in injured tissue.
