After repeated, successful extradural injections in a parturient, the extradural catheter migrated into the subdural space. The injection of 3% chloroprocaine 10 ml resulted in an extensive block, which extended to the cranial nerves and paralysed the respiratory muscles. The position of the catheter tip was confirmed by fluoroscopy. Subdural injection should always be suspected when tests for ...

Recently, various studies of attack methods of round reduction differential fault analysis (DFA) using fault injection in block cipher-implemented microcontrollers have been reported. However, few studies have focused on the quantitative evaluation method of round reduction DFA vulnerability using detailed fault injection timing dependency of attack success rate. This is required to improve mic...

BACKGROUND Reversal of neuromuscular block can be accomplished by chemical encapsulation of rocuronium by sugammadex (Org 25969), a synthetic gamma-cyclodextrin derivative. The present study determined the time course of the reversal action of sugammadex on rocuronium-induced block in the anaesthetized Rhesus monkey using train-of-four stimulation. METHODS A bolus injection of rocuronium 100 ...

Background: Owing to the advanced age of patients scheduled for cataract and IOL insertion, and the high concentrations of local anesthetic used in peribulbar blockade, the use of ropivacaine produces an effective motor blockade with minimal risks for neuro and cardiotoxicity.concerning globe injury due to multiple injection the new single injection medial canthus is theoretically preferred to ...

BACKGROUND There is level II evidence that volunteers prefer the single subcutaneous injection in the midline of the proximal phalanx with lidocaine and epinephrine (SIMPLE) finger block over the classic two dorsal injection block technique. The purpose of this study was to possibly further decrease the pain of digital block injection by examining the effect of the duration of injection on the ...

background: successful anesthesia during root canal therapy may be difficult to obtain. intraosseousinjection significantly improves anesthesia’s success as a supplemental pulpal anesthesia, particularly incases of irreversible pulpitis. the aim of this study was to compare the efficacy of x‑tip intraosseousinjection and inferior alveolar nerve (ian) block in primary anesthesia for mandibular p...
