Background: Perineal trauma is a frequent complication to vaginal delivery especially with episiotomy. Discomfort and pain related to episiotomy interfere with women daily activities during postpartum period.

Objectives: Objectives of the study were to assess the degree of episiotomy wound healing before and after the administration of infrared radiation. To find out the association of infrared radiation on episiotomy wound healing and the selected demographic variables of postnatal mothers who underwent episiotomy.

Materials and methods: This study was pre-experimental study. The study was conducted at Govt. modern maternity Hospital, petlaburz, Hyderabad. Non probability Purposive sampling was used and 60 samples were selected. Structured questionnaire was used to collect the demographic data and episiotomy wound healing among postnatal mothers was assessed by using REEDA Scale.

Results: The intervention (infrared radiation) was provided for 10 minutes for all 60 postnatal mothers who underwent for episiotomy in this study. And the post test was done using the same REEDA scale. The average level of episiotomy wound healing got increased from 12.05 to 7.13 in postnatal mothers. The paired t test statistics (12.94) shows that the promoted in level of episiotomy wound healing as a result of the intervention of infrared radiation is statistically significant at,< 0.01 level. At the end of the study concluded that infrared radiation is effective for episiotomy wound healing.

Discussion: After the pretest, the intervention (infrared radiation) was provided for 10 minutes twice a daily for three days to all 60 postnatal mothers in this study. And the post test was conducted for all the 60 postnatal mothers using the same REEDA scale. After the statistical analysis it was found out that in the post test, around 16(26.67%) had mild infection and 44(73.33%) had moderate infection. There were no postnatal mothers had severe infection in the post test.
