A randomised clinical trial of the effect of low-level laser therapy for perineal pain and healing after episiotomy: A pilot study

Effect of low‐level laser therapy on pain and perineal healing after episiotomy: A triple‐blind randomized controlled trial

“…Similar results from a previous study indicated that after LLLT irradiation, there was no difference between the scores of episiotomy healing and perineal pain up to 2 hours, 20–24 hours, and 15–20 days after normal birth. The effects of LLLT on perineal pain following an episiotomy were also not significant in a Brazilian study that compared the irradiation of infrared laser, red laser, and simulation.…”

“…A pilot study and a clinical trial evaluating the effect of LLLT on perineal pain and episiotomy healing did not find any significant difference in outcome between the experimental and control groups, due to ineffective irradiation parameters, such as low wavelength, irradiation time, energy/point, energy/session, power, and total energy.…”

Low‐level laser therapy for pain relief after episiotomy: a double‐blind randomised clinical trial

“…Therefore, it was not possible to randomise the women during the pregnancy period. As in the pilot study, the use of analgesics may be considered both a limitation of this study and a pragmatic condition because there is usually no way to avoid women receiving routinely prescribed medication (Santos et al. 2011).…”

“…Non‐pharmacological therapies are not used for perineal pain relief. A detailed description of this service is part of the pilot study that supported the current study (Santos et al. 2011).…”

“…The laser current application protocol was based on data from the pilot study (Santos et al. 2011), which used a laser diode with only a red light beam, a dose of 3·8 J/cm 2 , 15 mW power, energy of 0·15 J per point and total energy of 0·45 J per application.…”
