OBJECTIVE To conduct a cost-effectiveness analysis of anesthetic agents to reduce the pain of peripheral intravenous cannulation in an emergency department (ED) setting. DESIGN Cost-effectiveness analysis in which costs were measured as the cost of the agent plus costs associated with time in the ED using data from our hospital cost accounting system. Outcomes were measured as improvements in...

A 40-year-old woman with hypertensive nephrosclerosis began haemodialysis in January 2009. In March 2010, she underwent placement of a left forearm straight Polytetrafluoroethylene (PTFE) haemodialysis graft for haemodialysis. She became increasingly intolerant of graft cannulation due to the pain of skin puncture and was prescribed a topical local anaesthetic preparation (EMLA). Within 3 weeks...

Intralesional steroid injections are the standard treatment for hypertrophic scars and keloids. The procedure is, however, quite painful and is unpopular with patients because of this. Topical application of anesthetic creams, such as Ametop gel (tetracaine) and EMLA cream (lidocaine and prilocaine), has limited efficacy because of poor drug penetration. The onset of the analgesic effect is als...

OBJECTIVE To investigate the efficacy and safety of dorsal penile nerve block (DPNB) and eutectic mixture of lidocaine (EMLA) for palliation of pain associated with circumcision in low-birth-weight infants. DESIGN Randomized, blinded, controlled trial. SETTING Intensive care nursery (step down unit) at Georgetown University Medical Center, Washington, DC. PARTICIPANTS Fifty neonates with ...

OBJECTIVE To determine the relative efficacy of lidocaine-prilocaine and tetracaine for procedural pain in children. METHODS Systematic review was performed (MEDLINE1990-June 2001) of all studies comparing the efficacy of these 2 modalities of pain relief in children undergoing painful cutaneous procedures. Search terms included lidocaine, prilocaine, tetracaine, and anesthesia. RESULTS Eig...

BACKGROUND Topical anesthetics are commonly applied for a variety of indications. Several lidocaine-containing topical anesthetics are available for purchase over the counter (OTC). Recently, the authors' group has shown that there is great interindividual discrepancy in the manner in which lidocaine is absorbed and metabolized for even a single OTC product. OBJECTIVES The authors compare fiv...

OBJECTIVE The aim of this investigation was to compare the pharmacokinetics of lidocaine and prilocaine in two groups of 10 patients undergoing intravenous regional anaesthesia. METHOD The study had a randomized design. The patients were allocated to one of the two groups of 10. Each group received either lidocaine (200 mg = 0.855 mM) or prilocaine (Citanest, 200 mg = 0.909 mM), injected intr...

PURPOSE Transrectal ultrasound-guided prostate biopsy is the procedure of choice for diagnosing prostate cancer. We compared with pain-relieving effect of acetaminophen, a known drug for enhancing the pain-relieving effect of tramadol, and eutectic mixture of local anesthetics (EMLA), a local anesthetic agent, with that of the conventional periprostatic nerve block method. MATERIALS AND METHO...

BACKGROUND Comprehensive international travel preparation often requires several vaccines. Up to 90% of adults have some fear of injections, mostly due to injection-related pain. Pediatric studies with routine vaccines have shown topical anesthetic EMLA cream (lidocaine and prilocaine, Astra Pharmaceuticals, Inc.) and the topical vapocoolant Fluori-Methane (dichlorodifluoromethane and trichloro...
