Background: While local anesthetics are essential drugs in dentistry, risks such as paresthesia are associated with their use. The purpose of this study was to analyze the reported paresthesia cases in the United Kingdom. Methods: Voluntary reports of paresthesia from local anesthetic use between 1998 and 2008 obtained from UK’s Yellow Card Scheme were examined. Statistical significance was tes...

PURPOSE We describe a new, modified jet injection technique for local anesthesia for no-scalpel vasectomy without the use of a needle, which may minimize the fear of vasectomy in men due to the needle involved in local anesthesia. MATERIALS AND METHODS A MadaJet Medical Injector (MADA Medical Products, Carlstadt. New Jersey) was used in this study to deliver a high pressure spray of 0.1 cc lo...

Effective local anesthesia is arguably the single most important pillar upon which modern dentistry stands. Paradoxically, the injection of local anesthetic is also perhaps the greatest source of patient fear, and inability to obtain adequate pain control with minimal discomfort remains a significant concern of dental practitioners. Although the traditional aspirating syringe is the most common...

Methods: A crossover randomized study of IVRA with a forearm tourniquet was conducted on 14 male healthy volunteers. This study was performed, once using manual injection of local anesthetic and once using automatic pump injection, on two separate sessions. In both techniques, 0.3 ml/kg lidocaine 0.5% was injected over 90 seconds. The occlusion pressure, continuous venous pressure and the serum...

amitriptyline, a tricyclic antidepressant agent is used as one of the analgesic drugs in different kinds of pain. in the present study the effect of local (subcutaneous) injection of amitriptyline (50 and 100 µg) on the acute and chronic pain using formalin test, was investigated. our data show that local injection of amitriptyline to the paw receiving formalin, causes a decrease in pain in bot...

The anterior cutaneous branches of the thoracolumbar spinal nerves enter the rectus sheath at its lateral border and perforate the muscle after travelling a short distance in the ventral direction. In this anatomical case series, we show that dye injection at the medial margin did not lead to reliable impregnation of the target nerves. The local anesthetic should therefore be injected at the la...

Thorasic paravertebral block (PVB) thorasic epidural and pectoral nerve blocks can be used as a regional anesthetic option for breast surgery. Thorasic PVB is defined as injection of local anesthesthetic solution at the site where spinal nerves emerges from paravertebral foramen. It produces unilateral motor, sensory and sympathetic block, hence PVB could be an anesthetic choice in patients wit...

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 toxicity,...

The objective of reporting this case is to highlight the clinical usefulness of chloroquine in the management of scorpion sting pain with the hope of stimulating interest and research, especially in areas where local anesthetic agents may not be available. In this case reported here, lidocaine failed to provide sustained analgesia for pain relief following scorpion sting. Two milliliters of par...

Introduction: We previously reported a case using caudal morphine for pediatric liver transplantation. A 3-yr-old, 14.9 kg child received a caudal injection of 0.6 mg of preservative free morphine sulfate as well as 110 mcg of intravenous fentanyl. Also, the surgical incisions were infiltrated with 20 ml of 0.125% bupivacaine1. However, a question arose as to the impact of the local anesthetic ...
