OBJECTIVE Block of the sciatic nerve at the popliteal fossa can be performed using the ultrasound machine; it may be proximally or distally to the bifurcation of the sciatic nerve using lateral, medial, or posterior approaches. It is frequently used for surgeries below the knee specially the foot and ankle operations. PURPOSE This study compares one and two injections of the sciatic nerve in ...

BACKGROUND Exact location of the needle tip during nerve stimulation-guided peripheral nerve blocks is unknown. Using high-frequency ultrasound imaging, we tested the hypothesis that intraneural injection is common with nerve stimulator-guided sciatic nerve (SN) block in popliteal fossa. METHODS Forty-two patients scheduled for hallux valgus repair were studied. Sciatic block at the popliteal...

BACKGROUND The aim of this study was to compare the efficacy of axillary brachial plexus block using an ultrasound-guided method with the nerve stimulator-guided method. We also compared the efficacy of ultrasound-guided single-injection with those of double-injection for the quality of the block. METHODS Ninety patients scheduled for surgery of the forearm or hand were randomly allocated int...

BACKGROUND We conducted prospective, randomized, observer-blinded trial to compare two double-injection perivascular (PV) ultrasound-guided techniques of axillary brachial plexus block (BPB). METHODS American Society of Anesthesiologists physical status I-II, 50 patients undergoing surgery of the forearm, wrist or hand were randomly allocated to two groups. For PV12 group, injection was carri...

mean total dose of 0.5 per cent bupivacaine injected epiduraUy was 8.1 +0.26 ml (range 5-10 ml). The subarachnoid block usually extended from $5 to T7 dermatomes. The usual upper level of the CSE block after injection of local anaesthetic via the epidural catheter was T4. In six patients (25 per cent) the subarachnoid block reached the T4-5 level and further extension of block by epidural injec...

Three millilitre of plain 0.5% bupivacaine was injected intrathecally at two different levels in two groups of 20 patients. Injection at the L2/3 space produced a significantly higher spread of analgesia (mean T7 (SD 3.9)) than injection at L4/5 (T11(1.8)). The range of the cephalad spread of the block was less in the L4/5 group (P less than 0.001 at 60 min). The spread of anaesthesia continued...

OBJECTIVE Axillary plexus block is one of the widely used technique for upper extremity surgery. In this study, we retrospectively evaluated the single injection axillary plexus block technique we used in our rutine anesthesia practice, between August 2010-March 2011. METHODS Medical records of ASA I-III, 40 17 female and 23 male patients who underwent elective single injection axillary block...

Sir,—I agree entirely with this view that paravertebral block would provide reduction in requirement for morphine, greater than that achieved with the intercostal block used in our technique. Several of the chest radiographs, including the one in the article, demonstrated contrast medium in the paravertebral space. The statement "it should not be assumed that an intercostal injection of contras...

As increasing numbers of anesthetists perform eye block anesthesia, thorough understandings of peribulbar injection techniques are important for safe practice. There is uncertainty in the literature regarding the optimum needle length, entry point, volume of injectate, and use of single vs double-injection techniques. A modified technique of peribulbar block anesthesia is presented, which offer...
