Project Description

The Effect of Low-Level Laser on Postoperative Pain After Tibial Fracture Surgery: A Double-Blind Controlled Randomized Clinical Trial

Background

Postoperative pain is a common complication that can lead to serious morbidities and delayed recovery.

Objectives

The aim of this study was to investigate the effect of low-level laser therapy on acute pain after tibial fracture surgery.

Patients and Methods

In this randomized clinical trial, 54 patients who were candidates for tibial fracture surgery were allocated randomly to two groups, namely, control and laser therapy. Both groups had the same type of surgery and technique of spinal anesthesia. Patients in the laser group were treated with the combination of two lasers (GaALAs, 808 nm; and GaALInP, 650 nm) at the end of the surgery while the control group received laser in turn-off mode with the same duration as the laser group. Patients were evaluated for pain intensity according to the visual analogue scale (VAS) and the amount of analgesic use during 24 hours after surgery.

Results: Laser group experienced less pain intensity in comparison with the control group at the second, fourth, eighth, 12th, and 24th hours after surgery (P-Value < 0.05). In addition, the amount of consumed opioid in the laser group was significantly less than the control group (51.62 ± 29.52 and 89.28 ± 35.54 mg, respectively; P-Value, 0.008).

Conclusions

Low-Level Laser Therapy is a proper method to reduce postoperative pain because it is painless, safe and noninvasive and is easily accepted by patients.
