ABSTRACT
OBJECTIVES: Due to their developmental characteristics, adolescents have a higher probability than other age groups of experiencing injuries caused by accidents, violence, and intentional self-harm. The severity and characteristics of injuries vary by the intentionality and mechanism of injury; therefore, there is a need for a national-level estimate of the scale and the severity of injuries in adolescents that takes these factors into account. METHODS: By using data from the Emergency Department-based Injury In-depth Surveillance Data, National Emergency Department Information System, the Korean National Hospital Discharge In-depth Injury Survey, and cause of death statistics, we calculated the emergency department (ED) visit rate, hospitalization rate, and death rate of injuries per 100 000 adolescents for each injury mechanism. The calculated rates were used to generate the injury pyramid ratio (ratio of death rate to hospitalization rate to ED visit rate) to visualize the scale and the severity of the injury. RESULTS: The mortality rate in adolescents due to injury was 10/100 000; the corresponding rates for hospitalization and ED visits were 1623 and 4923, respectively, resulting in an injury pyramid ratio with the general pyramid form, with a 1:162:492 ratio of deaths to hospitalizations to ED visits. The mortality rate due to suicide/intentional self-harm was 5/100 000, while 35 were hospitalized for this reason and 74 made ED visits. The pyramid ratio of 1:7:15 for intentional self-harm/suicide showed a steep pyramidal form, indicating considerable lethality. The mortality rate due to motor vehicle collisions (MVCs) was 3/100 000; 586 were hospitalized for this reason, while 1023 made ED visits. The pyramid ratio of 1:195:341 for MVCs showed a gradual pyramid form, indicating that the lethality was low and the scale of injury was high. CONCLUSIONS: The main categories of injuries in adolescents were visualized in pyramid form, contributing to an understanding of the scale of each injury by mechanism in terms of levels of death, hospitalization, and ED visits. These findings will be helpful for understanding how to prioritize injuries in adolescents.

PURPOSE: The incidence and severity of injuries differs between each region of Korea due to socioeconomic differences. The comparative analysis between national injury data and the evaluation of regional epidemiologic characteristics is useful in establishing an injury prevention strategy for a regional community. This study was conducted in order to provide basic data for the establishment of an injury prevention strategy by priority through comparison between national injury data collected by National Emergency Department Information System (NEDIS) and injury data from regional emergency centers located in small cities, in Korea. METHODS: The study subjects were the injury patients who visited a total of 117 regional, specialized and local emergency centers from April 2009 to March 2010, as well as those who visited Konkuk University Chungju Hospital during the same period. We collected national data from the Injury Surveillance Report published by Korea Centers for Disease Control and Prevention and compared these with study hospital data collected by our own injury registration system to include gender, ratio, age, and mechanism and severity of patient injury. RESULTS: Of 3,931,573 patients who visited 117 emergency centers and 23,671 patients who visited the study hospital during the study year, the number of injury patients was 786,006 (20.0%) versus 6,177 (26.1%), respectively. 485,521 (62.0%) of the nation-wide subjects versus 4,046 (65.5%) of the study hospital subjects were male, and 298,197 (38.0%) of the nation-wide subjects versus 2,128 (34.5%) of the study hospital subjects were female. The comparison by age of the injury subjects was as follows: below 9 years (22.4% versus 16.8%), twenties (14.5% versus 16.3%) and forties (14.5% versus 15.2%). In the comparison of injury mechanism, blunt injury was higher (20.4%) in nation-wide subjects followed by slip injury (20.0%) and transport accident (19.0%). Transport accidents produced the highest cause of injury (26.0%) in the study subjects followed by slip injury (20.1%) and bunt injury (16.1%). In the severity comparison, 641,344(81.6%) versus 4797(77.8%) were mild injury patients, 139,260(17.7%) versus 1299(21.1%) were severely injured, and 3114 (0.4%) versus 69(1.1%) were fatal injuries. The causes of severe injury nation-wide included intoxication (46.3%), falls (34.8%) and machine accidents (33.3%) versus machine (46.0%), asphyxia (44.4%), intoxication (39.3%) in the study hospital, and the causes of fatal injuries nation-wide were intoxication (5.2%), drowning (4.3%), and asphyxia (4.2%), versus drowning (11.1%), asphyxia (5.6%) and intoxication (4.9%) in the study hospital. CONCLUSION: Through the comparison between study hospital with national injury data, we found that the percentage of severe and fatally injured patients was higher in the nationally with transportation related accidents being highest in terms of mechanism. The construction of a regional injury data system with ongoing comparison with national injury data may be useful in the establishment of a regional injury intervention strategy by priority.

BACKGROUND: Tracheal intubation stimulates the sympathetic nervous system, resulting in hypertension, tachycardia and sometimes critical complications, especially in patients with underlying hypertension, cardiovascular disease or cerebrovascular disease. In this study, we sprayed 4% lidocaine into the trachea before intubation, and observed the hemodynamic changes after tracheal intubation. METHODS: We randomly allocated 87 patients, whose ASA physical status was I or II, into three groups. The 4% topical lidocaine was sprayed before intubation at the following specific times: just before intubation (group 0), or 1 minute (group 1) and 2 minutes before intubation (group 2). For maintenance of anesthesia, TIVA (total intravenous anesthesia; propofol-remifentanil infusion with orchestra(R)) was used. We observed hemodynamic changes between the groups just after the intubation, as well as 1, 3 and 5 minutes after the intubation. Hemodynamic changes were also monitored in the same group. RESULTS: When the patients arrived at the operating room, we found no significant difference in heart rate and arterial pressure between the groups. However, heart rate after intubation in group 1 was significantly lower than group 0. The diastolic and mean arterial pressure just after intubation were lower in group 1 and 2 than in group 0. CONCLUSIONS: Spraying lidocaine 1 or 2 minutes before intubation was more effective than spraying it just before intubation for reducing hypertensive responses after intubation.

PURPOSE: This study was conducted to survey children's health status and need of customized visiting health care services in one province. METHODS: The participants in this study were 237 caregivers of infants and preschoolers. Data were collected at the participant's home or public health center. RESULTS: Many of the children did not receive developmental screening tests or dental examinations. In the beneficiary group, the prenatal checkup rate and children's vaccination rate were lower, and caregivers had more health problems than the other groups. On the assessment of home safety, unsafe conditions were more frequently found in the beneficiary group. The caregivers in the beneficiary group showed lower child rearing confidence than the other groups, and wanted customized visiting health care services most in the areas of developmental screening, regular health check-up and counseling, nutritional supplementation, and oral health care. CONCLUSION: These results indicate that it is necessary for children and parents in poverty to be provided with professional home visiting interventions for the promotion of child health and prevention of developmental problems and diseases. These findings can be used for developing future customized visiting health care service programs for infants and children in this community area.

BACKGROUND: The purpose of this study was to determine the optimal dose of remifentanil for minimizing hemodynamic changes during intubation and reducing propofol-induced pain in elderly patients. METHODS: In a randomized prospective study, 60 patients (ASA I-II, elder than 65 years) were enrolled to determine which of two target remifentanil blood concentrations (3 ng/ml, 5 ng/ml) was required to blunt hemodynamic changes during intubation and to reduce propofol-induced pain. After the target effect site concentration of remifentanil had been reached, the target controlled infusion of propofol was started and propofol-induced pain was recorded. Blood pressure and heart rate were recorded at baseline, just before intubation and 1, 3, 5 min after intubation. RESULTS: There were no significant differences in the hemodynamic parameters between two groups, but not in arterial pressure at just before intubation and 1 minute after intubation. However, the group R5 (5 ng/ml) showed significantly less intense pain induced by propofol than in the group R3 (3 ng/ml). CONCLUSIONS: The results suggest that the group R5 provide more relief in propofol induced pain than the group R3, but showed great possibility of hypotension and bradycardia in both groups, which means it should be used with cautions in the elderly patients.

PURPOSE: Assess the appropriate level of electrocardiography (EKG) education that should be incorporated into the curriculum of emergency medical technician (EMT) students. METHODS: Consensus by EMT professors and emergency medicine specialists was obtained using two rounds of the Delphi survey. The questionnaire consisted of 70 items; 12 related to demographic information, 8 related to general interpretation of EKG, 26 related to interpretation of arrhythmia, 20 related interpretations of structural anomaly, infarction and systemic disease, and 4 related to interpretation of EKG findings used for advanced cardiac life support. We considered consensus to be agreement of greater than 7 of 9 (66.7%). RESULTS: 59 and 24 subjects were included in the first and second rounds of the Delphi survey, respectively. The response rate was 59% for the first round and 40.7% for the second round. Of 70 items, 40 items came to a consensus by the panel. All items related to interpretation of EKG and advanced cardiac life support and most (10 of 12) items related to basic content were felt to be important by both EMT professors and emergency medicine specialists. However, for items related to arrhythmia and related to structural anomaly, infarction and systemic disease, less than half of the items examined were felt to be necessary in the curriculum of EMT students (12 of 26 and 6 of 20). CONCLUSION: We identified 40 items that should be included into the EKG curriculum of EMT students. These findings should be used to create more effective educational programs for EMT students.

BACKGROUND: Propofol produces anesthesia with rapid recovery but also causes pain on injection. This study was designed to evaluate the effects of two different concentrations of remifentanil for minimizing the pain caused by propofol and to compare the hemodynamic changes during propofol-remifentanil infusion. METHODS: In a randomized, double-blind study of 80 patients, we compared the severity of the injection pain of propofol between two groups of patients. The initial effect-site target concentration of remifentanil was set at 4 ng/ml (the R4 group, n = 40) or 8 ng/ml (the R8 group, n = 40). After the effect-site concentration of remifentanil was achieved, the infusion of propofol was started with the concentration of 4 microgram/ml. The remifentanil-related complications were evaluated and the severity of the pain caused by propofol was compared by using a four-point scale during the propofol infusion. The heart rate and arterial blood pressure were measured at pre-induction, just before intubation and at 1 minute after intubation. RESULTS: The severity of injection pain of propofol was significantly lower in the R8 group than in the R4. There was no significant difference in the incidence of remifentanil-related complications between the two groups. Compared with the pre-induction values, the heart rate and arterial blood pressure were significantly lower at pre-intubation and at 1 minute after intubation in the R4 and R8 groups. CONCLUSIONS: Pretreatment with an effect-site concentration of 8 ng/ml remifentanil may be useful for minimizing the propofol injection pain compared with 4 ng/ml remifentanil.

BACKGROUND: The addition of remifentanil during propofol TCI (target controlled infusion) attenuates the hemodynamic changes induced by endotracheal intubation. This study examined the optimal effect-site concentration of remifentanil to minimize the cardiovascular changes to endotracheal intubation in elderly patients. METHODS: Fifty ASA 1 or 2 elderly patients scheduled for elective surgery under general anesthesia were assigned randomly to one of two groups according to the effect-site concentration of remifentanil. Each group was administered 4 microgram/ml of propofol TCI with 1 ng/ml (group R1) or 3 ng/ml (group R3) of remifentanil. The heart rate (HR), systolic (SAP), mean (MAP) and diastolic arterial pressure (DAP) were measured at pre-induction, before and after endotracheal intubation. RESULTS: After intubation, the HR, SAP, MAP and DAP increased significantly in the two groups compared with the pre-intubation values. However, the HR, SAP, MAP and DAP for group R3 were lower than group R1 for 5 min after intubation. CONCLUSIONS: In elderly patients administered 4 microg/ml of propofol TCI, we suggest that the optimal effect-site concentration of remifentanil to minimize the cardiovascular changes to endotracheal intubation is 3 ng/ml rather than 1 ng/ml.

BACKGROUND: Glidescope(R) is a video-assisted intubation device.It offers a clear view and is easy to use, giving it several advantages over conventional intubation devises.This study was designed to compare the hemodynamic effects and POGO scores between conventional and video laryngoscopic intubation. METHODS: Sixty adult patients with ASA 1 or 2 were randomly allocated into two groups; Glidescope(R) (group G) or Macintosh (group M).Anesthesia was induced with propofol and remifentanil.Blood pressure and heart rate were recorded just prior to intubation and 1, 3, and 5 minutes after intubation.POGO scores, intubation time and the severity of sore throat were also recorded. RESULTS: There were no significant differences in SBP, MBP, DBP, HR, POGO score, intubation time and the severity of sore throat between two groups. CONCLUSIONS: The POGO scores and hemodynamic changes associated with tracheal intubation using the Glidescope(R) were almost the same as that of the Macintosh group.
