In 1865, Bowman was the first to recog­ nize the clinical entity of pupillary block, which he observed more frequently after cataract extraction without iridectomy than after cataract extraction with iridectomy. Bowman described this condition only as occurring shortly after discission of a sec­ ondary cataract. From his description it may be surmised that the mechanism in­ volved was obstructi...

BACKGROUND Accidental intraneural injection induced nerve injury is an iatrogenic tragedy and intramuscular injection (IM) is the most common injury mechanism affecting the sciatic nerve. The most frequent presentation of sciatic nerve injury includes radicular pain and paresthesia with almost immediate onset of variable motor and sensory deficit. OBJECTIVES Intraneural injection is a common ...

 Abstract Background: Different adjuvant drugs have been used with local anesthetics in order to decrease the time of onset and elongate the duration and quality of regional blocks. This study was performed to study the effects of one of the adjuvants, verapamil, in supraclavicular block. Methods: In this double blinded clinical trial, we divided 60 ASA class I and II patients who were to under...

conclusions ct epidurography is not closely correlated with a clinical assessment of epidural block; thus, a clinical assessment of the sensory block is mandatory. the use of opioid analgesia in combination with local anesthetics may compensate for the lack of efficacy of local anesthetics alone. objectives the primary objective of this study was to evaluate, by ct imaging and digital multiplan...

PURPOSE Total knee replacement is one of the most painful orthopedic procedures, and effective pain relief is essential for early mobility and discharge from hospital. The aim of this study was to evaluate whether addition of single-injection femoral nerve block to epidural analgesia would provide better postoperative pain control, compared to epidural analgesia alone, after total knee replacem...

Background Rectus sheath block is a common peripheral nerve block for patients undergoing umbilical hernia repair surgery. However, rectus sheath block alone can affect only anterior branches of intercostal nerves and, therefore, is incomplete for postoperative analgesia for the anterior abdomen, which is innervated by both anterior and lateral branches. We describe a successful perioperative a...

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...
