conclusion lumbar medial branch nerve block under ultrasound guidance was associated with high rates of treatment success and excellent treatment outcomes for facet joint pain. it is also feasible and administers no radiation. thus, ultrasound-guided procedures can be used instead of conventional methods. results the success rate was 98% (87/89 blocks), which was due to our use of ultrasound gu...

background: dental procedures in the maxilla typically require multiple injections and may inadvertently anesthetize facial structures and affect the smile line. to minimize these inconveniences and reduce the number of total injections, a relatively new injection technique has been proposed for maxillary procedures, the anterior and middle superior alveolar (amsa) nerve block, which achieves p...

background and aims:  using methods such as pulsed radiofrequency (prf) and nerve blocks are among the methods used in pain clinics to treat facet-originating low back pain. this study compares two methods of pulsed radiofrequency and facet joint block (fjb)regarding pain recovery and improving disability of patients suffering from facet-originating low back pain. material and method: 50 patien...

Nerve block can eliminate spasms and chronic pain. Kilohertz frequency alternating current (KHFAC) produces a safe and reversible nerve block. However, KHFAC-induced nerve block is associated with an undesirable onset response. Optical inhibition using infrared (IR) laser light can produce nerve block without an onset response, but heats nerves. Combining KHFAC with IR inhibition [alternating c...

background and aims: infraclavicular nerve block (icnb) is one of the most efficacious peripheral nerve blocks for upper extremity procedures, associated with several potential complications. recently, some authors have recommended ultrasound-guided peripheral nerve block for icnb. the current study is aimed to compare the outcomes of icnb utilizing combined ultrasound guidance and neurostimula...

UNLABELLED BACKGROUND The widespread of hallux valgus surgery in a day care setting enhanced the role of regional anaesthesia in the last few years. Sciatic nerve block at popliteal fossa has been shown to provide safe and effective analgesia. Our purpose was to compare the success rate and performance time of popliteal block during resident's training for regional anaesthesia by using nerve...
