Does Low‐Level Laser Therapy Enhance The Efficacy of Intravenous Regional Anesthesia?

Abstract

Intravenous regional anesthesia (IVRA) is useful during short surgeries, but is not effective against pain due to tourniquet applications or postoperative pain. Several attempts have been made to identify a useful technique that can be coadministered with IVRA to reduce postoperative and tourniquet-related pain. The present study represents one such attempt, in which the authors combined IVRA with low-level laser therapy and assessed the effects on pain following surgical fixation of distal radial fractures.

The Effect of Photobiomodulation on the Depth of Anesthesia During Endodontic Treatment of Teeth With Symptomatic Irreversible Pulpitis (Double Blind Randomized Clinical Trial)

“…11 It has been reported in some studies that PBM can be effective in anesthesia and pain, the addition of gallium-aluminum-arsenide laser irradiation to intravenous regional anesthesia is safe, and reduces pain during and after the operation. 4 The results of these 2 studies was in line with our study. It is natural that with increase numbness, need for supplemental anesthesia is reduced.…”

“…3 Nowadays photobiomodulation (PBM) is considered as an adjunct in anesthesia, the addition of galliumaluminum-arsenide laser irradiation to intravenous regional anesthesia is safe, and reduces pain during and after the operation. 4 The most local anesthetics in dentistry block sodium channels. Tetrodotoxin resistance sodium channels are resistant to local anesthetics and sensitized by prostaglandins.…”

“…Tetrodotoxin resistance sodium channels are resistant to local anesthetics and sensitized by prostaglandins. 5 PBM has been used in dentistry for its anti-inflammatory, 6 regeneration 7 and analgesic 4 properties. It can prevent nerve impulse conduction.…”

The Effect of Lidocaine Infusion on theAcute Pain after the Surgery of Tibia Fracture under General Anesthesia

“…The main neuroendocrine response to such pain stimulus is activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis that increases the sympathetic tone, the catecholamines, and the secretion of the catabolic hormones (Akhondzadeh ., 2017). Uncontrolled pain after surgery causes several acute complications such as coagulation disorders, hemorrhage, thrombosis, immune suppression, hyperglycemia, slow wound healing, intensif ication of the sympathetic system, blood pressure increase, risk of Myocardial Infarction (MI), dysfunction in bowel movements, and reduced activity and dysfunction of the respiratory system (Nesioonpour ., 2014). Preemptive analgesic approach during perioperative period can reduce postoperative pain complications, hospitalization period and consequently the therapeutic costs.…”

“…In a preemptive analgesic strategy, different methods are used before and during operation to prevent the stabilization of the afferent nerves, which reinforce the postoperative pain toward the central nervous system (Akhondzadeh ., 2017). Epidural analgesia, systemic opioids, local anesthetics, and non-steroidal anti-inflammatory drugs (NSAIDs) are common methods used in preemptive analgesic approaches (Ballantyne, 2006;Nesioonpour ., 2014). Each of these methods and drug administration has their own advantages and disadvantages.…”
