The evaluation of a program’s behavior in the presence of transient faults is often a very time consuming work. In order to achieve significant data, thousands of executions are normally required and each execution will have the significant overhead of the fault injection environment. Our previously published methodology reduced significantly the time needed to evaluate the robustness of a prog...

background and aims. inferior alveolar nerve block injection is one of the common intra oral anesthetic techniques, with a failure rate of 15-20%. the aim of this study was to evaluate the position of the lingula as an index for this injection. materials and methods. thirty eight panoramic radiographs of 7–11 year old patients were analyzed and the distance between the lingula index and occlusa...

background and aims . dentists administer thousands of local anesthetic injections every day. injection to a highly vascular area such as pterygomandibular space during an inferior alveolar nerve block has a high risk of intravascular needle entrance. accidental intravascular injection of local anesthetic agent with vasoconstrictor may result in cardiovascular and central nervous system toxicit...

A typical Iranian carbonate matrix block surrounded by an open fracture was modeled in order to understand the fracture-matrix interaction and realize how to model the interaction best. The modeling was carried out by using a fine-scaled Eclipse model in the single porosity mode (the fractures were explicitly modeled). The model was extended to a stack of 6 matrix blocks to understand block-to-...

Introduction: As endotracheal intubation is the first action which must be done for serious and very ill patients , so any procrastination leads to dangerous consequences including aspiration and finally death. Routine method for endotracheal intubation is injection of intravascular diazepam- Pethidine and sometimes muscle relaxants , but these drugs in Patients with GCS under 7 cause more decr...

BACKGROUND The optimal site for local anesthetic placement during ultrasound-guided infraclavicular block remains controversial. METHODS Patients were randomized to receive lidocaine 2% 30 mL as a single injection posterior to the axillary artery (n = 51) or a triple injection ideally adjacent to each brachial plexus cord (n = 49). Pinprick sensory and motor block (3 = no block, 0 = complete ...

we present a case of unexpectedly prolonged motor and sensory block following a successful single injection ultrasound – guided infraclavicular block with bupivacaine (0.25%) and dexamethasone (8 mg). ultrasound guidance and safety measurement such as injection of the local anaesthetic at a slow rate and verifying that usual resistance was felt throughout the injection, has been applied. it too...
