This study is to assess the impact of sanitary pads infused with active oxygen and negative ions on episiotomy pain, wound healing, and postpartum physical symptoms in primiparous women. Participants will be randomly allocated to either the intervention group, utilizing active oxygen and negative ion pads, or the control group, employing normal postpartum pads. The research will assess pain intensity, recovery advancement, and physical manifestations during the initial postpartum phase. The objective is to ascertain if the intervention offers supplementary advantages relative to usual care.

Episiotomy is a surgical incision made during vaginal birth to enlarge the vaginal opening and support delivery. Although it can help prevent complications during childbirth, many women experience pain, discomfort, difficulty sitting, and delayed wound healing after the procedure. In the postpartum period, appropriate hygiene and wound care are essential to reduce discomfort, prevent infection, and support the healing of the perineal area. The tissues around the vulva and vagina become more sensitive due to increased moisture and hormonal changes, making the choice of hygiene products particularly important.

Sanitary pads containing active oxygen and negative ions have recently been introduced as a new type of hygiene product. These components are believed to improve comfort, support wound healing, and reduce irritation. Although their clinical effects in the postpartum period have not yet been extensively studied, their potential benefits make them a promising option for women recovering from episiotomy.

This study aims to examine whether sanitary pads with active oxygen and negative ions can reduce episiotomy pain, support wound healing, and decrease postpartum physical symptoms in primiparous women. Participants will be randomly assigned to either the intervention group using these special pads or the control group using standard postpartum pads. The findings may contribute to determining whether these products offer additional advantages in the early postpartum recovery process.
