ABSTRACT

OBJECTIVE: This study examined the clinical characteristics of suicide attempters who exposed their suicidal intension to suggest an active intervention strategy for suicide prevention based on the regional emergency medical service system. METHODS: A prospective database of suicide attempters who visited the emergency department of Chungbuk National University Hospital between October 2013 and December 2017 was used. All of the adult patients who provided consent for the initial assessment for suicidal attempters were eligible, excluding cases with unknown exposure of suicidal intension. The primary and secondary endpoints were the risk factors affecting exposure to the suicidal intension and characteristics of the exposure group. The adjusted odds ratios (AORs) of exposure to suicidal attempts after adjusting for potential confounders was calculated. RESULTS: Of a total 1,035 suicidal attempters enrolled, 332 (32.1%) were included in the exposure group. The exposure group was more likely to have an educational level above high school and no religion, and have suicidal characteristics at night time (18:00–08:00), under the influence of alcohol, suicidal plan before 1 week, and suicidal method involving asphyxia (P<0.05). The exposure group was more likely to have no guardian (AORs, 1.46; 95% confidence interval [CI], 1.00–2.12), use methods involving asphyxia (AORs, 2.07; 95% CI, 1.46–2.91), and attempt suicide at night (18:00 to 08:00) (AORs, 1.38; 95% CI, 1.05–1.83) compared to the no exposure group. CONCLUSION: Models need to be established, where regional mental health welfare center, local government, fire headquarter, and tele-communication companies can participate in the implementation of an active intervention strategy.

ABSTRACT

PURPOSE: This study aimed to identify predictive factors for decreased blood pressure in patients prescribed with propacetamol in the emergency room using clinical and laboratory indicators of sepsis. METHODS: Among patients aged 18 years or older with a fever, who visited Chungbuk National University hospital's emergency room between July and December of 2014, 246 patients underwent intravenous infusion of propacetamol to control body temperature. Of these, 112 patients fulfilled all study requirements. Patients whose systolic or diastolic blood pressure dropped below 90 mmHg or 60 mmHg, respectively, were included in the blood pressure decline group. Additional inclusion criteria were a decline in systolic blood pressure of more than 30-mmHg and thereby treated with fluids or inotropics after intravenous infusion of propacetamol. Remaining patients were included in the blood pressure maintenance group. The relationship of each factor between the two groups was then investigated. RESULTS: Twenty-nine patients (25.9%) showed a significant decrease in blood pressure, and among many factors, high-sensitivity C-reactive protein (hs-CRP) (cut off value, 11.86; sensitivity, 72.4%; specificity, 69.9%; area under curve [AUC], 0.698) and procalcitonin (cut off value, 0.67; sensitivity, 75.9%; specificity, 60.2%; AUC, 0.667) levels showed a statistically significant effect. Of the 29 patients with a decrease in blood pressure, 10 patients received fluids and inotropics; procalcitonin in particular showed a significant effect. CONCLUSION: When propacetamol is administered to patients at the emergency room, and if hs-CRP or procalcitonin levels are high, there is an increased risk of a decrease in blood pressure. In particular, if procalcitonin levels are high, aggressive treatment is required, such as administration of inotropics in addition to fluids.

ABSTRACT

PURPOSE: Facial scars are a main complaint of patients who had undergone suture in the emergency department. Therefore, effective techniques for minimizing scar formation are required. W-plasty, a widely used method of scar correction, has been performed to change the scar direction or divide it into multiple segmented scars. This method can be applied in the initial stage of wound repair in the emergency department. The aim of this study was to investigate the effectiveness of direct application of W-plasty to the wound in simultaneously accomplishing the aforementioned objectives. METHODS: This was a prospective study, from June 2012 to June 2014. Either simple debridement or W-plasty for facial laceration was performed in 31 patients. In patients in the simple debridement group, the excision was made along the laceration margin. In patients in the W-plasty group, the excision was made within the W-form predesigned margin of the laceration. The prognosis was evaluated using the Stony Brook scar evaluation scale (SBSES). RESULTS: Among 31 patients, 15 underwent simple debridement and 16 underwent W-plasty. In procedure time, there was no significant difference between the two groups. No complications were observed in either group. The median SBSES score was 4 (IQR, 3-4) in the simple debridement group and 5 (IQR, 5-5) in the W-plasty group, indicating a significant difference between the two groups (p<0.001). CONCLUSION: We achieved good results of direct W-plasty application to wound lacerations in terms of minimal scar formation. Thus, for patients with facial lacerations, we suggest that application of W-plasty to the wound debridement is more effective than the classic simple debridement.

ABSTRACT

PURPOSE: Hydrofluoric acid (HFA) causes injury via tissue penetration by the free fluoride ion. Methods for treatment of HFA burns include continuous intra-arterial infusion of calcium gluconate, which is especially useful for patients with dermal burns of the digits caused by HFA. However, no comparative study of tissue injury grade with clinical factors among patients with HFA burns treated with continuous intra-arterial infusion of calcium gluconate has been conducted in Korea. METHODS: We conducted a prospective study at the emergency department of a university teaching hospital between January 2011 and June 2013. The subjects enrolled in this study consisted of 33 patients with HFA burns. After completion of treatment, we divided the patients into three groups according to the type of skin lesions. Patients requiring a skin graft or surgical flap were included in the poor outcome group, those who had to undergo incision and drainage in the moderate outcome group, and those who did not require further treatment in the good outcome group. RESULTS: After completion of all treatments, 22 of the 33 patients were included in the good outcome group and seven in the moderate outcome group; the remaining four patients were included in the poor outcome group, as they met the above-mentioned criteria, experienced longer-lasting pain, and were more frequently treated with injection in comparison with the other patients. CONCLUSION: Patients with HFA burns with long-term pain who need frequent arterial injections despite undergoing intra-arterial calcium gluconate treatment are likely to have poor outcome; therefore, they require more proactive interventions.
