Ultrasound-guided supraclavicular brachial plexus block.
UNLABELLED In this study, we evaluated state-of-the-art ultrasound technology for supraclavicular brachial plexus blocks in 40 outpatients. Ultrasound imaging was used to identify the brachial plexus before the block, guide the block needle to reach target nerves, and visualize the pattern of local anesthetic spread. Needle position was further confirmed by nerve stimulation before injection. T...
متن کاملUSING PHYSICAL EXAMINATION IN SUPRACLAVICULAR BRACHIAL PLEXUS BLOCK WITH MODIFIED PARASCALENE APPROACH
Background: Because nerve stimulators are not always available for brachial plexus block, fmding the right injection spot for nerve blocks is important. In this study we used physical examination to determine the appropriate spot for injection. Methods: All patients who were candidates for upper extremity surgery and were either in class ASA I or ASA II, were selected. Paresthesia was elici...
متن کاملSupraclavicular Brachial Plexus Block for Arteriovenous Hemodialysis Access Procedures.
Ultrasound-guided supraclavicular brachial plexus block using 1% and 2% lidocaine in 21 procedures is reported. Average procedure time was 5.1 minutes (± 1.2 min; range, 2-8 min). Average time of onset and duration were 4.8 minutes (± 3.7 min; range, 0-10 min) and 77.9 minutes (± 26.7 min; range, 44-133 min), respectively, for sensory block and 8.4 minutes (± 5.7 min; range, 3-23 min) and 99 mi...
متن کاملPredicting successful brachial plexus block using changes in skin electrical resistance.
Skin electrical resistance is determined by the degree of sweating of the skin which is, in turn, related to sympathetic nervous system activity in the area concerned. It is increased when the nerves supplying the area are damaged or blocked by local anaesthetic agents. We have assessed the temporal and spatial relationship between the onset of sympathetic and sensory loss in the hand following...
متن کاملAssessment of Pulse Oximeter Perfusion Index in Pediatric Caudal Block under Basal Ketamine Anesthesia
Whether pulse oximeter perfusion index (PI) may be applied to detect the onset of caudal block in pediatric patients under ketamine intravenous basal anesthesia is investigated. 40 ASA I, 2-8-year-old boys scheduled for elective circumcision surgery were randomized into two groups. Group I: 20 patients were anesthetized by 2 mg·kg(-1) ketamine intravenous injection (IV) followed by caudal block...
