Four cases of cauda equina syndrome occurring after continuous spinal anesthesia are reported. In all four cases, there was evidence of a focal sensory block and, to achieve adequate analgesia, a dose of local anesthetic was given that was greater than that usually administered with a single-injection technique. We postulate that the combination of maldistribution and a relatively high dose of ...

Adjunctive local anesthetic techniques and their armamentaria, such as intraosseous injection, computer-controlled delivery systems, periodontal ligament injection and needleless jet injection, have been proposed to hold particular advantages over conventional means of achieving local anesthesia. This article describes the use of each technique and proprietary armamentarium and reviews the lite...

BACKGROUND Prilocaine-lidocaine emulsion (EMLA) has been used successfully as a local anesthetic in patients undergoing superficial procedures. OBJECTIVE The purpose of this study was to investigate the analgesic effect of the patch as a local anesthetic for children undergoing a skin biopsy procedure. The effect on both the pain at the injection site and the pain of the biopsy was investigat...

OBJECTIVE To analyze the side effects and complications following intraosseous anesthesia (IA), comparing them with those of the conventional oral anesthesia techniques. MATERIAL AND METHOD A simple-blind, prospective clinical study was carried out. Each patient underwent two anesthetic techniques: conventional (local infiltration and locoregional anesthetic block) and intraosseous, for respe...

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 ...

AIM The aim of this study was to evaluate the efficacy of, and patients' subjective responses to, periodontal ligament (PDL) anesthetic injection compared to traditional local-anesthetic infiltration injection for the nonsurgical extraction of one posterior maxillary permanent tooth. MATERIALS AND METHODS All patients scheduled for nonsurgical symmetrical maxillary posterior permanent tooth e...

This is a case report of successful use ultrasound for stellate ganglion (SG) blocks in CRPS I 11 patients using local anesthetic bupivacaine with injection dexmedetomidine as an adjunct. Ultrasound helped us to deposit Local anesthetics target area without any noticeable side effects and trauma adjacent structures.
