The evaluation of low level laser therapy using the diode laser in enhancement of episiotomy wound healing

Abstract EN

Objectives: This study aimed to evaluate the effect of low level laser therapy (biostimulation) using the diode laser with wavelength of (790-805) nm in promotion and enhancement of wound healing of episiotomy.

Women, materials and methods: thirty women (22 of them were primipara) with episiotomy wound were selected and divided into three groups, 1st group (group No.1: control group) given antibiotics without laser therapy, in the 2nd group (group No.2) the wound exposed to laser therapy (4 sessions, each session with energy density 8 joule /cm2 every other day ) and antibiotics for 1 week, and in the 3rd group (group No.3) the wounds were exposed to laser therapy (4 sessions, the same as in the 2nd group) but without antibiotics.

Results: Those patients who exposed to LLLT showed significant reduction in the level of pain and tenderness after the 1st laser exposure, and rapid healing process that occur within seven (7) days, and the results were about to be equal in both (group II & group III), while group I showed prolonged period of healing (9-11) days with moderate to severe pain and tenderness that interfered with their sitting and walking and one case ended with dehiscent wound.

Conclusions: LLLT can be used to enhance surgical wound healing, & to induce analgesic effects if proper wavelength, energy density and exposure time are selected.
