Purpose: Hypovolemia is not uncommon among trauma patients in the emergency department (ED). Successful resuscitation of a hypovolemic patient often requires rapid intravenous administration of massive amounts of fluid. A rapid fluid infuser is used in the ED for this purpose, there have been no studies of their clinical uses and effectiveness. We studied clinical experience with a rapid fluid infuser at an urban university hospital in Seoul, Korea. Methods: We reviewed the medical records of 38 patients admitted to the ED with a history of application of a rapid fluid infuser from January 2004 to July 2005. Adult trauma patients older than 15 years of age were included in this study. Clinical data on the patients and the volume of fluid used to achieve a stable blood pressure were extracted from their medical records. Results: The total number of adult trauma patients with a history of application of a rapid fluid infuser from January 2004 to July 2005 in the ED was 16. The mean systolic blood pressure for deciding to apply the rapid fluid infuser was $74.9{\pm}12.7mmHg$. The mean time and volume used to achieve a stable blood pressure were 40.4 min and$2947.3{\pm}1339.2ml$, respectively. In all patients, the amount of fluid infused before using the rapid fluid infuser was between 500 ml and 10,000 ml, compared to 1,000 ml and 6,200 ml with the rapid fluid infuser. The mean amount of fluid per min. via the rapid fluid infuser was 85.5 ml. Vital signs were stabilized in 11 patients, 6 of the 11 were discharged alive. Conclusion: The mean amount of fluid delivered per min. via the rapid fluid infuser was much less than expected; thus, there should be clinical guidelines on volume resuscitation with a rapid fluid infuser in the ED. In the future, prospective, multicenter, clinical-data collection is needed for a more sophisticated study.

Purpose: The life expectancy of patients with spinal muscular atrophy (SMA) type I is generally considered to be less than 2 years. Recently, with the introduction of proactive treatments, a longer survival and an improved survival rate have been reported. In this study, we analyzed the natural courses and survival statistics of SMA type I patients and compared the clinical characteristics of the patients based on their survival periods. Methods: We reviewed the medical records of 14 pediatric patients diagnosed with SMA type I during a 9-year period. We examined the demographic and clinical characteristics of these patients, calculated their survival probabilities, and plotted survival curves as on the censoring date, January 1, 2010. We also compared the characteristics of the patients who died before the age of 24 months (early-death, ED group) and those who survived for 24 months or longer (long-survival, LS group). Results: The mean survival time was $22.8{\pm}2.0$ months. The survival probabilities at 6 months, 12 months, 18 months, 24 months, and 30 months were 92.9%, 92.9%, 76.0%, 76.0%, and 65.1%, respectively. Birth weight was the only factor that showed a statistically significant difference between the ED and LS groups ($P$=0.048). Conclusion: In this study, the survival probabilities at 2 years were far greater than expected. Because of the limited number of patients and information in this study, the contribution of improved supportive care on longer survival could not be clarified; this may be elucidated in larger cohort studies.

Purpose: The dog bite injury is expected to increase as westernizing lifestyle and the number of pet raisers increase. The bite injuries may cause serious sequelae. The purpose of this study is to contributes to establish a suitable management and treatment principle for domestic situation with a clinical analysis data of the dog bite injuries. Methods: We reviewed the hospital records of 76 patients with dog bite injuries who were treated in the emergency unit or out patient department of our hospital from January 2000 to May 2006. Results: The majority of patients were children less than 10 years of age, 21 case(27.6%). Injuries occurred most often in May and 14 patients(18.4%) were bitten by the kinds of Cockerspaniel. By Lackmann's classification, 36 patients(47.4%) had Stage I injuries, 27 patients (35.5%) Stage II, 11 patients(14.5%) Stage III and 2 patients(2.6%) Stage IVa. The most frequent injury site was the head and neck area with 55 cases(72.4%). Also, 58 cases(76.3%) were received the initial treatment within 30 minutes after being bitten and the most of case except emergency operation repaired within 3 days.Conclusion: The dog bite injuries increased by more than 20% every year over the study period and it says that it may continue to increase more in the future. However, There are little report or literature for suitable management and treatment principle for domestic situation. The authors think this clinical analysis data and treatment experience can be useful for establishing a suitable treatment principle for domestic situation.

8-isoprostane (8-$isoPGF_{2{\alpha}}$) is a reliable marker and considered a gold standard for lipid peroxidation. There are very few reports of 8-isoprostane levels in cancer patients, and in patients undergoing chemotherapy. Oxidative stress is however expected and has been observed in patients with cancer. This study measured 8-isoprostane levels in urine by ELISA of 25 patients undergoing chemotherapy for advanced non-small cell lung cancer, at cycles 1, 2, and 3 of treatment. It considers the creatinine clearance of the patients, and correction of 8-isoprostane levels by creatinine clearance, and overnight urine volume methods. The average 8-isoprostane levels in urine increased more than 6 to 12 fold on chemotherapy treatment, from $532{\pm}587$ pg/mL at cycle $1,6181{\pm}4334$ at cycle 2, and $5511{\pm}2055$ at cycle 3. Similar results were obtained if 8-isoprostane levels were corrected for overnight urine volume, giving averages of $285{\pm}244{\mu}g$ at cycle $1,4122{\pm}3349$ at cycle 2, and $3266{\pm}1200$ at cycle 3. No significant difference was seen in average total overnight urine volume or number of urinations between chemotherapy cycles except for a large variation in urine volume between cycle 2 and 3. Creatinine levels were significantly different only between cycles 1 and 2 (p=0.016). In conclusion, cisplatin therapy has been shown to induce high levels of lipid peroxidation in lung cancer patients and can be assessed from the 8-isoprostane marker in overnight urine, with or without urine volume correction.

Purpose: The establishment of the trauma system has changed the quality of trauma care in many countries. As one of the first designated level I trauma centers in Korea, we hypothesized that there were changes in laparotomy patterns and subsequent survival rates after the center was established. Methods: This was a 5-year retrospective study of all severe hemoperitoneum patients who were transfused with more than 10 units of packed red blood cells (RBCs) within 24 h of hospitalization. Variables related to trauma were collected throughout the study period, and the patients admitted before (period 1) and after (period 2) the establishment of a trauma center were compared. Results: Forty-five patients were managed from January 2009 to March 2015. The baseline patient characteristics of the two groups, including age, Injury Severity Score, blood pressure, and hemoglobin levels, were similar. The time to the operating room (OR) was $144.3{\pm}51.5$ min (period 1) and $79.9{\pm}44.1$ min (period 2) (p<0.0001). Damage control surgery (DCS) was performed in 17% of patients during period 1 and in 73% during period 2. The number of actual survivors (n=10) was higher than expected (n=8) in period 2. Conclusion: This is the first study analyzing the impact of a trauma center on the management of specific injuries, such as severe hemoperitoneum, in patients in Korea. During the study, the time to OR was shortened and DCS was used to a greater extent as a surgical procedure.

Background/Aims Potassium-competitive acid blockers are expected to be the next generation of drugs for the treatment of diseases caused by gastric acid. In 2015, vonoprazan fumarate, a novel potassium-competitive acid blocker, was approved by the Japanese health insurance system. Since its approval, patients refractory to vonoprazan can be encountered in clinical settings. We designed this study to clarify the pathophysiology of gastroesophageal reflux disease refractory to vonoprazan. Methods In this retrospective study, we involved patients who had refractory symptoms after administration of standard-dose proton pump inhibitors or vonoprazan and underwent diagnostic testing with esophageal high-resolution manometry and 24-hour multichannel intraluminal impedance and pH monitoring while using proton pump inhibitors or vonoprazan. Patients were diagnosed based on the Rome IV criteria for functional gastrointestinal disorders and diagnostic test results. Results Twenty-seven patients were analyzed during this study. Gastric pH ${\geq}4$ was sustained for a longer period of time, and the esophageal acid exposure time and number of acid reflux events were shorter in the vonoprazan group than in the proton pump inhibitor group. The percentage of patients diagnosed with acidic gastroesophageal reflux disease in the vonoprazan group was lower than that in the proton pump inhibitor group. Conclusions Intra-gastric pH and acid reflux were strongly suppressed by 20-mg vonoprazan. When patients with gastroesophageal reflux disease present symptoms after administration of 20-mg vonoprazan, the possibility of pathophysiologies other than acid reflux should be considered.

Background: The objective of the present study was to examine the status of patients who had received dental treatment under intravenous (IV) sedation at Chungnam Dental Clinic for the Disabled in Korea from its inception to the present time, and to review the analysis results. Methods: Retrospective analysis was performed on 305 cases of patients who had received dental treatments under IV sedation between January 2011 and May 2016. The analysis examined the patient's sex, age, primary reason for IV sedation, duration of anesthesia and dental treatment, type of dental treatment performed, number of clinical departments involved in the dental treatment and level of multidisciplinary cooperation, and annual trends. Results: Most dental treatments using intravenous sedation were performed on medically disabled patients or dentally disabled patients with an extreme gag reflex or dental phobia. The mean duration of IV sedation was 72.5 min, while the mean duration of treatment was 58.0 min. The types of dental treatments included surgical treatment (n = 209), periodontal treatment (n = 28), prosthodontic treatment (n = 28), restorative treatment (n = 23), implant surgery (n = 22), endodontic treatment (n = 9), reduction of temporomandibular joint dislocation (n = 1), and treatment of traumatic injuries (n = 1), with treatments mostly performed on adult patients. Conclusions: With increasing demand for minimally painful treatment, cases using IV sedation are on an upward trend and are expected to continue to increase.

Purpose: This study attempted to propose the basic framework for spiritual nursing intervention by understanding live spiritual experiences of terminal cancer patients. The study duration was from July 2002 to January 2003, and the subjects of this study were patients who were expected to live less than six months. The number of subjects was six and the average time of each interview was about an hour. Method: The data were analyzed using the method of phenomenological study analysis, which Colaizzi (1978) proposed. Result: Through live spiritual experiences. terminal cancer patients showed complex emotion about the Absolute, human, disease, and death: depended on the Absolute through recognizing death and spiritual acknowledgement: recollected the past life: accepted death believing salvation and immortality: recovered relationships with others through forgiving and reconciling with the Absolute and neighbors. Also, they pursued the meaning of pain. death, and life while feeling pain: demanded love and concern to the Absolute and neighbors: had a sense of futility about life and a hope for the future life: transcendental energy towards the world after death. Wishing to have a peaceful end to life. they felt peaceful and comfortable. Conclusion: Terminal cancer patients want to meet a peaceful end to life with a hope for the future and accept the meaning of death with peace and comfort minds(##-minds), which will allow them to carry on peaceful and satisfactory days for the rest of their lives. Thus, it is very important for caregivers to let them have spiritual experiences and care for them.
