In cesarean section incision, like as any other surgery, there is possibility of delay in wound healing. According to studies, flaxseed oil is effective in wound healing. This study was performed with aim to determine the effects of flaxseed oil on cesarean wound healing.
This three-blind randomized clinical trial was performed on 120 women with cesarean section at educational hospitals of Imam Reza and Shahid Hasheminejad of Mashhad in 2018. Individuals were randomly assigned to three groups (flaxseed ointment, placebo, control). In two groups of flaxseed ointment and placebo, the ointment was applied on cesarean section wound for 8 consecutive days and twice a day, each time as one finger strap. Wound healing was measured 24 hours after surgery, 4th and 8th day after cesarean section by REEDA Scale. Data were analyzed using SPSS software (version 25), and Chi-Square and Kruskal-Wallis tests. P <0.05 was considered statistically significant.
According to the results of statistical tests, there was statistically significant difference between flaxseed group with control and placebo groups in terms of cesarean section wound healing on days 4 and 8 after the intervention (P <0.001). In addition, in the intergroup comparison, Friedman test showed that in all three groups, the variation of REEDA scale in different days was significantly different (P <0.001).
Regarding the reduction of REEDA cesarean wound score after the intervention, flaxseed oil is recommended as a suitable drug for cesarean section wound healing in mothers.
