BACKGROUND Epidural steroid injection (ESI) is one of the most common procedures for patients presenting low back pain and radiculopathy. However, there is no clear consensus on what constitutes appropriate steroid use for ESIs. To investigate optimal steroid injection methods for ESIs, surveys were sent to all academic pain centers and selected private(More)
OBJECTIVES This randomized, double-blind, placebo-controlled trial evaluated intraperitoneal (IP) lidocaine administration and intravenous (IV) lidocaine infusion for postoperative pain control after laparoscopic cholecystectomy (LC). METHODS Patients who underwent LC were randomized to either group IV (intravenous lidocaine infusion), group IP(More)
A 60-year-old man presented with pain on the left cheek and lateral nose. The patient had been diagnosed with facial herpes zoster in the left V2 area 6 months previously. Medical treatment was prescribed for 6 months but it had little effect. We blocked the left infraorbital nerve under ultrasound guidance, but pain relief was short term. Therefore, we(More)
OBJECTIVE To compare the efficacy of ramosetron, midazolam, and the combination of ramosetron and midazolam in the prevention of postoperative nausea and vomiting (PONV) in female patients undergoing thyroidectomy. METHODS Patients were randomized to receive 0.3 mg ramosetron (Group R), 75 µg/kg midazolam (Group M) or 0.3 mg ramosetron combined with 75(More)
BACKGROUND The preemptive intravenous injection of local anesthetics is known to improve postoperative pains in abdominal surgery. The aim of this study is to assess the effect of intravenous lidocaine injection and analyze the precise amount of pain by computerized patient-controlled analgesia (PCA) in patients who had undergone laparoscopy-assisted distal(More)
Postherpetic neuralgia (PHN) is one of the most difficult pain syndromes to treat. Invasive treatments may be considered when patients fail to obtain adequate pain relief from noninvasive treatment approaches. Here, we present three cases of PHN in the mandibular branch treated with ultrasound-assisted mental nerve block and pulsed radiofrequency treatment.(More)
BACKGROUND Despite the suitable characteristics of ropivacaine as an epidural analgesic agent, such as better preservation of motor function and less neurotoxicity, we are aware of no data on its clinical application in pain management following lumbar spine surgery. The purpose of the present study was to evaluate the preemptive analgesic effects and(More)
BACKGROUND The aim of this study was to assess whether intraperitoneal administration of ginseng total saponins (GTS) has antihyperalgesic effects in a rat model of incisional pain. The proinflammatory responses and reversal of the antihyperalgesic effect of GTS by N-methyl-d-aspartate (NMDA) or naloxone were also evaluated. MATERIALS AND METHODS Rats(More)
BACKGROUND Vaccine use has been increasing worldwide, and adult populations are presented with more opportunities to experience pain from vaccine injection. The insertion of a needle through the skin is the most common source of iatrogenic pain, and needle phobia is a major concern in medical practice.
