The combination of transcricothyroid membrane ultrasonography and ultrasonographic lung-sliding evaluation could be useful in confirming endotracheal intubation in the ED.

Background and Objectives：We performed this study to evaluate the common carotid artery intima-media thickness (CCA IMT), and its correlation with several clinical variables, including the 10 year coronary heart disease (10 Yr CHD) risk in both healthy and hyperlipidemic hypertensive (HH) Koreans. Subjects and Methods：This was a multi-centered prospective epidemiological study. The study population consisted of 227 healthy subjects without risk factors, with the exception of age (mean 49 years old, 114 males), and 243 HH subjects (mean 51 years old, 120 males). The carotid IMT and presence of plaques were semi automatically measured in both carotid arteries at a central reading facility. Results：Linear regression analysis of all the subjects revealed that the independent factors of both CCA IMT were age, pulse pressure (PP) and HDL-cholesterol, and that of the right CCA IMT were sex and 10 Yr CHD risk. In healthy subjects, the independent factor of both CCA IMTs was age, and that of the right CCA IMT was body weight. In the HH subjects, age, sex, total cholesterol, HDL-cholesterol and PP were independent factors of both CCA IMTs, but 10 Yr CHD risk was an independent factor of only the right CCA IMT. Carotid plaques were seen in 17% of the healthy subjects and 35% of the HH subjects. An ROC curve analysis showed a right CCA IMT of 0.646 mm and left CCA IMT of 0.656 mm demonstrated 60% sensitivity and specificity in differentiating healthy from HH subjects. Conclusion：This result reliably demonstrates the Korean CCA IMT, as well as several other significant pieces of information. (Korean Circulation J 2005;35:513-524) KEY WORDS：Carotid arteries；Korea.

BackgroundSevere or massive postpartum hemorrhage (PPH) has remained a leading cause of maternal mortality for decades across the world and it results in critical obstetric complications. Recombinant activated factor VII (rFVIIa) has emerged as a gold standard adjunctive hemostatic agent for the treatment of life-threatening PPH refractory to conventional therapies although it remains off-licensed for use in PPH. We studied the effects of rFVIIa on coagulopathy, transfusion volume, prognosis, severity change in Korean PPH patients.MethodsA retrospective review of medical records between December 2008 and March 2011 indicating use of rFVIIa in severe PPH was performed. We compared age, rFVIIa treatment, transfusion volume, and Sequential Organ Failure Assessment (SOFA) score at the time of arrival in the emergency department and after 24 hours for patients whose SOFA score was 8 points or higher.ResultsFifteen women with SOFA score of 8 and above participated in this study and eight received rFVIIa administration whereas seven did not. Patients’ mean age was 31.7 ± 7.5 years. There was no statistically significant difference in initial and post-24 hours SOFA scores between patients administered rFVIIa or not. The change in SOFA score between initial presentation and after 24 hours was significantly reduced after rFVIIa administration (P = 0.016).ConclusionsThis analysis aimed to support that the administration of rFVIIa can reduce the severity of life-threatening PPH in patients. A rapid decision regarding the administration of rFVIIa is needed for a more favorable outcome in severe PPH patients for whom there is no effective standard treatment.

Purpose: Cultivator accidents are frequent and often lead to abdomino-perineal organ injury and, if severe, to death. This study presents the clinical characteristics, outcomes, and factors associated with mortality in patients who sustained an abdomino-perineal organ injury in cultivator accidents.Methods: We retrospectively analyzed the records of 53 patients who visited the emergency department of a tertiary hospital with abdomino-perineal organ injuries caused in cultivator accidents from April 2005 to March 2010.Results: All 53 patients had visited other medical institutions before visiting our hospital. Their mean age was 64.0± 11.1 (range, 20-80) years and 32 (60.4%) patients were 65 or older. The male-to-female ratio was 46:7. The chief complaint was abdominal pain (38 cases, 71.7%). The 53 patients included 41 cultivator operators (77.4%), 11 passengers (20.8%), and 1 passerby (1.9%). The causes of the injuries included a direct impact of the handlebar in 20 cases (37.7%), a rollover in 21 cases (39.6%), a fall in 10 cases (18.9%), and a wheel in two cases (3.8%). Several of the 53 patients had injuries to multiple abdomino-perineal organs, and the injured organs included the liver (23 cases, 26.4%), spleen (16 cases, 18.4%), pancreas (7 cases, 8.0%), small bowel (7 cases, 8.0%), mesentery (6 cases, 6.9%), adrenal gland (5 cases, 5.8%), and other organs. According to the abbreviated injury scale (AIS) dictionary, a thoracic injury was the most frequent co-injury (33 of 53 cases, 62.3%). Abdomino-perineal surgery was performed in 31 cases (58.8%) and angio-embolization was performed for six liver and two kidney injuries. Thirteen patients died (24.5%); all were males. The Injury Severity Scale (ISS) was lower in the survivors (17.8±8.5 vs. 27.0±16.0; p=0.010).Conclusion: With the aging of agricultural workers, safety education programs should be implemented. Furthermore, the patient transfer system in agricultural areas must be improved. [ J Trauma Inj 2015; 28: 60-66 ]
