BACKGROUND: Endotracheal intubation is one of the most important and challenging tasks that an emergency physician has to perform. Complications associated with this procedure range from local trauma of the airway to death caused by unrecognized misplacement of the endotracheal tube. This study was designed to investigate complications of intubation including rapid sequence intubation in the emergency department. METHOD: One hundred four consecutive patients requiring endotracheal intubation in the emergency department of the Stanford Medical Center over a 8-month period were studied prospectively. RESULT: The indications for incubation were acute respiratory failure(60.5%), airway protection(30.8%), and cardiopulmonary arrest(8.7%)). 97(93.3%)intubations were inserted orally, remaining 7(6.7%) were intubated via the nasotracheal route. Of 97 orotacheal intubations, sapid sequence incubation was used in 71(73.2%) cases. Grouped by level of training, junior residents attempted 69(66.3%) intubations, senior residents 21(20.2%), and star 13(12.5%). Of the 104 intubations, 92(88.5%) were successful on the flit or second attempt. 12 procedures(11.5%) required more than two attempts at intubation. A total of 36(34.6%) complications occurred. Esophageal incubations occurred in 13 cases, right main stem intubation in 13, pulmonary aspiration in 4, and others in 6. Fourteen patients(13.5%) died after intubation. CONCLUSION: The complication rate of endotracheal intubation in the emergency department is high. In order to decrease the complication, detailed knowledge, skill, and equipments about endotracheal incubation are required. The good condition of a patient before incubation appears to be important far survival.

Inflammatory mediators, such as oxidants, TNF-alpha, and IL-6, play a major role in the systemic response to bum injury It has been known that a continuing inflammatory response cause a sepsis and subsequent multiple organ failure. Recent studies have shown that burn patients receiving recombinant human growth hormone(rhGH) therapy have an improvement of the general condition, but the mechanism by which rhGH exerts its effects has not been clearly understood. The aim of this study was to evaluate the effect of rhGH on the early bum injury. Female Sprague-Dawley rats were divided into four groups : control group, bum group, burn plus rhGH treated group, and rhGH only treated group. Animals were killed at 30min., 3, 6, 24, and 48 hours after treatment. Histology and biochemical changes including malondialdehyde(MDA) content, tissue reduced glutathione(GSH) and catalase activity in the lung and liver, and plasma TNF-alpha and IL-6 levels were examined. Lung histology in the bum plus rhGH treated group showed decreased inflammtory response such as neutrophil and lymphocyte infiltrations, interstitial thickening, and edema compared with the bum group. Liver histology in the bum group revealed mild neutrophil and lymphocyte infiltrations, vacuolization .of hepatocytes, disrupted lobular structures, and dilated sinusoids. But liver histology of the bum plus rhGH was similar to control group. Lung and liver MDA in the burn plus rhGH and rhGH only treated groups were decreased with time compared with the burn group. Lung and liver GSH and catalase activities in the bum plus rhGH and GH only treated groups remained significantly increased compared with the bum group for the 48-hours period. Plasma TNF-alpha levels in the bum group remained elevated for the 48-hours period compared with the bum plus rhGH and rhGH only treated groups. Plasma IL-6 levels in the burn group were significantly increased only at first compared with the bum plus rhGH and rhGH only treated groups. These results suggested that rhGH showed inhibitory effects on the inflammatory cell infiltration and lipid peroxidation in the lung and liver after bum injury. Increased GSH levels and catalase activities seemed to be associated with the antioxidant effect of rhGH. But the inhibitory effect of rhGH on plasma TNF- and R-6 levels was not clearly demonstrated.

PURPOSE: Iodine contrast media used in computed tomography (CT) often induces nausea in patients. This study evaluated the prophylactic effect of metoclopramide against nausea induced by intravenous contrast media. METHODS: A prospective, double-blinded, randomized controlled trial was performed in the emergency department of an urban teaching hospital. Adult patients(>15 years old), who required enhanced CT scans, were infused with 52 ml normal saline solution mixed with either 10 mg/2 ml metoclopramide or 2 ml normal saline over 10 minutes prior to the CT scan. After the scan, the patients were asked about nausea. Patients who had any other cause for their nausea or had received metoclopramide prior to the study were excluded. RESULTS: In total, 69 patients were analyzed. The metoclopramide group contained 37 patients, and the placebo group contained 32 patients. Five patients in the placebo group complained of nausea(15.6%), whereas none of the patients in the metoclopramide group experienced nausea (Fisher's exact test, p=0.018). CONCLUSION: Metoclopramide can prevent nausea induced by intravenous iodine contrast media.

Toxic shock syndrome (TSS) is a rare but life-threatening illness that is mainly caused by toxigenic strains of Staphylococcus aureus. Although TSS is classically known to be associated with tampon use, the number of TSS cases with non-menstrual causes such as skin and soft tissue infection has been increasing. Tattooing can result in several complications such as localized and systemic infections, inflammatory skin eruptions and neoplasms. We recently experienced a 26-year-old man diagnosed with typical TSS following tattooing. He complained of fever, chills and erythematous rash at tattoo site. Subsequently, the patient developed sign of shock. The skin cultures on the tattoo site were positive for methicillin-sensitive Staphylococcus aureus. The patient was successfully treated with vasopressor infusion and intravenous antibiotics and was discharged without complications. On discharge from the hospital 7 days later, desquamations on the tattoo site, fingers and toes were observed.

BACKGROUND: The toxicity of paraquat has been known to be caused by oxygen free radicals which leads to the lipid peroxidation and multiple organ failure. Although vitamin C has been known to be a potent antioxidant, recently there are numerous data which have shown that a low dose of vitamin C may act as a prooxidant due to the stimulation of the Fenton reaction with metal ions, which produces hydroxyl radicals. It has been reported that a deferoxamine in paraquat intoxication could reduce the production of the hydroxyl radicals by the inhibition of the Fenton reaction through the reduction of iron ion in tissue. The aim of this study was to evaluate the effect of the high and low dose of vitamin C and deferoxamine on lipid peroxidation and plasma TNF-alpha in paraquat intoxication. METHODS: Female Sprague-Dawley rats were divided into seven groups: control group which was not given paraquat(20mg/kg), P group which was given paraquat only, PVH group given paraquat and high dose of vitamin C(100mg/kg), PVL group given paraquat and low dose of vitamin C(10mg/kg), PVHD given paraquat, high dose of vitamine C and deferoxamine(100mg/kg), PVLD given paraquat, low dose of vitamin C and deferoxamine, and PD given paraquat and deferoxamine. Animals were killed at 6 and 24 hours after treatment. Malondialdehyde(MDA), superoxide dismutase(SOD) and glutathione(GSH) contents, catalase activity, plasma TNF-alpha, and histologic changes in the lung and liver tissue were measured. RESULTS: The lung histology in the PVH and PD or PVHD groups showed the significant decreases in the alveolar edema and interstitial thickness compared to the P group. The liver histology in the PVH and PVHD groups demonstrated marked differences in the central venous and sinusoidal dilatation compared to that of the P group. While the MDA levels of the lung and liver in the PVH and PD groups showed the significant reduction compared to that of the P group at 6 hours after treatment, all groups showed the significant changes compared to the P group at 24 hours. There was no significant change of the SOD levels of the lung and liver at 6 hours among all groups. At 24 hours, the SOD levels of the lung in PVH, PVL, and PVHD groups showed the significant increases compared to the P group. The increase of the SOD level in groups combined with deforoxamine, however, revealed a little reduction. The SOD level of the liver in PVH group only significantly increased compared to the P group at 24 hours. There was no significant change of the GSH level of the lung and liver among all groups at 6 hours. At 24 hours, the GSH level of the lung and liver were significantly increased in both PVH and PD group and PVH group, respectively, compared to the P group. Although the catalase activity of the lung was not significantly increased, that of liver was significantly increased in both PVHD and PD groups compared to the P group at 6 hours. The catalase activities of the lung and liver were significantly increased in PVH, PD, and PVHD at 24 hours. The concentrations of the Plasma TNF-alpha were slightly decreased at 6 hours and slightly increased at 24 hours compared to that of the P group, but they were not significant. CONCLUSION: This study showed that although the low dose of vitamin C had no effect, the high dose of vitamin C revealed a decrease of the MDA level and an increase of SOD, GSH, and catalase activity in the lung and lung and liver tissues, and the effect of the high dose of vitamin C increased with time. The administration of the deferoxamine with or without high dose of vitamin C, however, significantly showed the inhibition of the lipid peroxidation and antioxidant effect and low dose vitamin C decreased the effect of deferoxamine. The effects of the vitamin C and deferoxamine on plasma TNF-alpha were not clearly shown.

BACKGROUND: Multi-organ failure from sepsis is very lethal disease entity, which is suspected to be caused by activated inflammatory cells. Inflammatory cells activated by endotoxins generate oxidants and cytokines such as TNF-alpha and IL-6, which in turn stimulate macrophages and neutrophils. Augmented inflammation makes an organ-injury deteriorate into an organ-failure, which may progress to multi-organ failure. This study is designed to evaluate the therapeutic effects of vitamin-C, a scavenger of oxidants, in sepsis. METHODS: Male Sprague-Dawley rats were divided into 3 groups : a control group, a group injected intrapetoneally with LPS(lipopolysaccharide), and a group injected intraperitoneally with LPS and vitamin-C. Each eight rats were sacrified 24 hours and 48 hours after injection, and samples of the blood, the liver and the lung were obtained. Biochemical assays of TNF-alpha level in the blood and malondialdehyde(MDA) level, catalase activity and nitric oxide synthase(NOS) activity in the liver and the lung tissues were performed. RESULTS: Serum TNF-alpha level, tissue lipid peroxidation and tissue i-NOS activity were dramatically increased, and tissue catalase activity was exhausted rapidly in sepsis. High dose vitamin-C administration decreased serum TNF-alpha level, tissue lipid peroxidation and tissue i-NOS induction, and protected against catalase exhaustion. CONCLUSION: high dose vitamin-C therapy was proved to have definite antioxidant effect in septic condition.

PURPOSE: For proper operation of the Seoul Emergency Medical Service Information Center, We analyzed the contents of the phone-calls made to the center. METHODS: We retrospectively analyzed phone calls made to the center from Jul. 1 to Sep. 30, 2001. RESULTS: The total number of phone calls made to the center during the above-mentioned period was 42,143, and the average number of calls was 458.1+/-32.3 per day. Most calls came between 09:00 and 12:00 (85 calls, 18.6%), and hours with the fewest calls were from 03:00 to 06:00 (18 calls, 3.9%). The average length of the calls was 2 minutes 38 seconds. Most callers(25,454 calls, 60.4%) asked questions about a disease or first aid which were considered as non-urgent, and 9,586 (22.7%) asked for simple advice about a hospital or a clinic and also considered as non-urgent. There were 885 (2.1%) calls that were considered as emergent situations and there were 1,686 cases (6.7%) connected to the Rescue system 1-1-9 for the rapid evacuation. CONCLUSION: The results show that the Seoul Emergency Medical Information Center does not perform the proper functions that it should in emergent situations.

PURPOSE: Tracheal intubation in a hemorrhagic airway is a difficult procedure because the visibility can be obscured by blood or vomitus. Several devices and methods have been developed to overcome such obstacles, but they are not available at all practical sites. Therefore, this study was conducted to assess the time and success rate of tracheal intubation according to the type of suction tip used in a hemorrhagic airway manikin model. METHODS: This study was a randomized crossover manikin simulation study. We recruited 18 emergency physicians to perform intubation with suction using a Yankauer suction tip and a polyvinyl chloride (PVC) catheter suction tip in a hemorrhagic airway manikin model. We then measured the time and success rate of intubation for each suction tip. RESULTS: The mean intubation time using the Yankauer suction tip was 42.3 seconds, and the mean intubation time using the PVC catheter suction tip was 91.1 seconds (p < 0.001). Two cases of esophageal intubation occurred when the PVC catheter suction tip was used (success rate, 88.9%). In contrast, there was no esophageal intubation when the Yankauer suction tip was used (success rate, 100%) (p=0.217). CONCLUSION: Intubation of a hemorrhagic airway manikin model can be performed in a shorter time when a Yankauer suction tip is used than when a PVC catheter suction tip is used.
