Purpose: The purpose of this study was to determined that the efficacy and comfort of iontophoretic transdermal delivery of lidocaine by comparison of local anesthetic duration, sensory threshold, pain threshold and pain tolerance levels according to four different cleansing regimes. Methods: Forty healthy volunteers were randomly assigned to four groups; oil cleansing group, lotion cleansing group, solution cleansing group and alcohol cleansing group. All subjects were received lidocaine iontophoresis on the forearm using direct current with 4 mA for 10 minutes. All subjects were measured the duration of local anesthesia after lidocaine iontophoresis, also evaluated the sensory threshold, pain threshold and pain tolerance level during iontophoresis. For comparisons of the efficacy and the sensory characteristics of iontophoresis within the groups, an one-way ANOVA was used. Results: The duration of local anesthesia were found significant difference between groups (p<0.001). The anesthetic duration in solution and alcohol cleansing groups were significantly longer than oil and lotion cleansing group by post hoc (p<0.05). Statistically significant difference were noted in respect to all sensory characteristics such as sensory threshold, pain threshold and pain tolerance between groups (p<0.001). The sensory threshold in solution and alcohol cleansing group were significantly lower than oil and lotion cleansing group by post hoc using Duncan multiple range test (p<0.05). The pain threshold and pain tolerance in solution and alcohol cleansing group were significantly higher than oil and lotion cleansing group by post hoc (p<0.05). Conclusion: These results demonstrated that cleansing regimes have affected the efficacy and discomfort of iontophoretic transdermal delivery of lidocaine. These findings indicate that cleansing agents without oil ingredient contributed to more comfort, and more successful achievement of the iontophoretic transdermal delivery.

Surgery on the distal trachea or the carina presents special problems for maintaining the airway and systemic oxygenation. Cardiopulmonary bypass is an alternative method for respiratory support for the patients with these conditions. Percutaneous cardiopulmonary support (PCPS) applied under local anesthesia has recently been used for respiratory support in tracheal surgery and the outcome is satisfactory. We encountered a patient who had severe distal tracheal stenosis after prolonged intubation. We had a gratifying result with performing tracheal resection and repair under the support of PCPS.

Xiphodynia is a term used to describe a painful xiphoid process, and this is a rare musculoskeletal disorder that can radiate to the anterior chest, epigastrium, neck, shoulders and back. Clinical awareness of xiphodynia is important for making its correct diagnosis. We report here on two cases of xiphodynia. The diagnosis was suggested by the reproduction of the anterior chest pain or/and the epigastrium pain with light pressure on the xiphoid process. The patient of case 1 had suffered from xiphodynia throughout the years, and this patient underwent surgical excision of the xiphoid process. The patient of case 2 received an injection of local anesthetic agent to the xiphoid process.

A concentration of 0.01 mM bupivacaine was necessary to maintain approximately 50% depression of contractility of rat atria suspended in a modified Krebs-Ringer bicarbonate glucose medium, pH 7.4 at $30^{\circ}C$. Sodium pyruvate, sodium acetate, and fructose partially restored the contractility of the bupivacaine-depressed atria. However, 20 mM glucose had no effect on the bupivacaine-depressed atria, although this concentration of glucose markedly increased the contractility of normal atria not to be exposed to bupivacaine. Contractility of normal atria was not significantly influenced by sodium pyruvate, sodium acetate, and fructose. The results suggested that at least part of the negative inotropic action of bupivacaine is the result of inhibition of glucose uptake or utilization in the glycolytic pathway, and further pinpoint the blockade as an early step in the glycolytic sequence prior to the phosphofructokinase step.

Propolis, a natural resinous compound collected from honey bees, contains many biochemical constituents and has been used in traditional medicines as early as 300 B.C. Recently, it has been reported to possess many biological activities such as antibacterial, antiviral, fungicidal, local anaesthetic, immunostimulating, antiinflammatory and free radical scavenging properties. This study was performed to investigate the pharmacological effects of the propolis extract and fractions on the gastric lesion and ulcer. The ethanol extract was fractionated with hexane, toluene and ethyl acetate. Followed by bioassay on antigastric and antiulcer activity. Propolis ethanol extracts(500, 750, 1,000, 1,500 and 2,000 mg/kg) showed the protective effect on HCl·ethanol-induced gastric lesion and the antisecretory effect against Shay’s gastric secretion in pylorus-ligated rats in a dose related manner. In the animal models of HCl·ethanol, aspirin-induced gastric lesion and Shay’s gastric secretion, the hexane and toluene fraction of propolis significantly reduced the length of gastric lesion and the acid secretion. These data showed that the gastric protective effects of propolis might result from reduction of acid secretion through the inactivation of H+/K+ATPase activity.

Background: Tramadol administered epidurally is known to have one-thirtieth the potency of morphine for treatment of pain following abdominal surgery. We designed a prospective, randomized, controlled study to evaluate the analgesic efficacy and safety of combined epidural infusion of bupivacaine and tramadol with 2-day infusor as ompared to bupivacaine and morphine combined epidural infusion. Methods: Sixty healthy women scheduled for Cesarean delivery were assigned randomly in double- blind fashion: Group 1 (n=20) were given a mixture of morphine 10 mg(1 ml), 0.5% bupivacaine 40 ml and normal saline(NS) 40 ml; Group 2(n=20) a mixture of tramadol 300 mg(6 ml), 0.5% bupivacaine 40 ml and NS 54 ml; Group 3(n=20) or a mixture of tramadol 500 mg(10 ml), 0.5% bupivacaine 50 ml and NS 50 ml, of continuous dose via epidural route following 1% lidocaine 6 ml as bolus dose for 48 hours postoperatively. We evaluated the analgesic efficacy and side effects of these three groups using visual analogue pain scale (VAPS) and verbal rating scale (VRS). Results: VAPS of group 1 and 3 were lower than group 2, and VAPS of group 1 was lower than group 3(12, 24, 36, 48 hours). VRS of group 1 and 3 were lower than group 2 (12, 24, 36 hours). There were incidences of pruritus was 16 patients in group 1. Conclusions: Tramadol does possess the analgesia effect of morphine, but has the added analgesia following increment. Further research to determine the most effective administration method and reguired dosage of tramadol is further needed.

We investigated the diffusive transport of bupivacaine HCl through the microchannels of microfluidic drug delivery devices. In the biodegradable microfluidic drug delivery devices developed in this research, the drug release rate can be controlled by simply modulating the geometrical parameters of the microchannels, such as the length, number, and cross-sectional area of the microchannels, when the microchannels are used as paths for drug release. However, the hydrophobic nature of a biodegradable polymer, 85/15 poly(lactic-co-glycolic acid), hinders the infiltration of a release medium (phosphate-buffered saline) through the microchannels into the reservoir of a device that contains bupivacaine HCl, at the early stage of drug release. This can have an adverse effect on the early stage release of local analgesic compounds from the device. In this study, microfluidic channels were surface-treated with surfactants such as PEG600 and Tween80, and the effects of the surfactants on the release performance are presented and analyzed.

Purpose: A eutectic mixture of local anesthetics (EMLA$^{(R)}$) cream has been used as a topical anesthetic to reduce the pain of procedures penetrating the skin. It is generally applied for 40 to 60 minutes before the painful procedure. Because of the long application period, EMLA$^{(R)}$ is not useful in the emergency department (ED). The purpose of this study was to determine whether a 20-minute application of 9.6% lidocaine would be useful in reducing the pain of routine peripheral intravenous cannulation in the ED. Methods: We examined 27 male and 19 female patients ages over 18 years of age who required intravenous cannula insertion. Intravenous insertion was performed on 46 patients: 24 patients in the placebo group (mean age: 40.0 years) and 22 in the 9.6% lidocaine group (mean age: 37.6 years). The 9.6% lidocaine or placebo gel was applied and covered with an occlusive dressing for 20 minutes. Pain was scored by the patients using a 0- to 10-cm visual analogue scale. Results: The patients in the 9.6% lidocaine group (mean pain score: 3.4) experienced less pain than those in the placebo group (mean: 5.3), and the difference was statistically significant (p=0.029). Conclusion: We concluded that a 20-minute application of 9.6% lidocaine is safe and effective for reducing pain associated with venipuncture.

Whereas a somatic pain notifies tissue damage, a neuropathic pain presents disorder of the nerve itself. The causes of neuropathic pains are trauma, infection, chronic irritation by adjacent tissue and so on. The iatrogenic trauma or infection also causes traumatic neuropathy, which may exert a bad influence on doctor-patient relationship. Some of related dental treatments are implantation (directly or indirectly through heating), root canal treatment, teeth extraction, block anesthesia, mandibular surgery. If inappropriate management is performed after nerve trauma, there will be many chances to develop chronic neuropathy for the patient. It is important that the sign of nerve trauma have to be caught by the practitioner as soon as possible and treated properly.
