BACKGROUND AND OBJECTIVES Perineural dexamethasone prolongs the duration of single-injection peripheral nerve block when added to the local anesthetic solution. Postulated systemic mechanisms of action along with theoretical safety concerns have prompted the investigation of intravenous dexamethasone as an alternative, with decidedly mixed results. We aimed to confirm that addition of intraveno...

Several cases of accidental subdural injection have been reported, but only few of them are known to be accidental intradural injection during epidural block. Therefore we would like to report our experience of accidental intradural injection. A 68-year-old female was referred to our pain clinic due to severe metastatic spinal pain. We performed a diagnostic epidural injection at T9/10 interspa...

UNLABELLED In 1973, Winnie et al. introduced the inguinal paravascular three-in-one block, which allegedly provides anesthesia of three nerves--the femoral, lateral cutaneous femoral, and obturator nerves--with a single injection. This concept was undisputed until the success of the obturator nerve block was reassessed by using evidence of adductor weakness rather than cutaneous sensory blockad...

OBJECTIVE To compare the traditional two injections dorsal digital block with volar block in terms of effectiveness of anaesthesia and pain of initial pinprick. STUDY DESIGN Quasi-experimental. PLACE AND DURATION OF STUDY AVH and casualty operation theatres, Mayo Hospital, KEMU, Lahore, from January to June 2007. METHODOLOGY Thirty patients requiring surgical procedure distal to proximal ...

Because of its rapid onset time, recent years have seen an increase in the use of ultrasound (US)-guided popliteal sciatic nerve block (PSNB) via subparaneural injection for induction of surgical anesthesia. Moreover, in below-knee surgery, combined blocks, as opposed to sciatic nerve block alone, have become more common. These combined blocks often require a large volume of local anesthetic (L...

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...

Affected by the high viscosity of crude oil, large injection-production well spacing, poor injection condition, and low oil recovery rate, overall development effect transition zone is poor, besides, produced degree utilization thin layer makes have some potential excavation. Under condition that current conventional measures to improve block are not clear, it necessary further optimize system....

BACKGROUND Intraneural injection during nerve-stimulator-guided sciatic block at the popliteal fossa may be a common occurrence. Although intraneural injections have not resulted in clinically detectable neurologic injury in small studies in human subjects, intraneural injections result in postinjection inflammation in animal models. This study used clinical, imaging, and electrophysiologic mea...

Background Serratus plane block is a thoracic truncal block that has been proposed as alternatives for analgesia such as epidural anesthesia and paravertebral block for the anterolateral chest wall. Previously, we performed the clinical study about optimal volume of the local anesthetic in serratus plane block. The primary aim of this study was to assess the pattern of distribution of dye into ...
