The purpose of this study is to develop a healthcare service based on standard protocol and information communication technology for mother's sustainable postpartum care. The developed service was consisted of a client area where mothers measure, manage and transmit their vital signs using their own smartphone and personal health devices, and a server area that manages and shares with the received mother's vital signs and the results of examination results and personal health records. The client area collects vital signs through the IEEE 11073 Personal Health Device (PHD) using the m-health application of the previous study and Continua Health alliance certified personal health devices and transfers to Health Level Seven (HL7) V2.4, Continuity of Care Record (CCR) and Continuity of Care Document (CCD). The server area consists of a mobile web that manages and shares the HL7 Fast Healthcare Interoperability Resources (FHIR)-compliant personal health records to ensure interoperability of examination results, and a mobile web where the postpartum caregiver enters and manages the results of the mother's examination results and provides it to the mother. In this way, the healthcare service of this study securing continued exchanges between the mother and postpartum caregiver improves the quality of life of the mother not only to satisfy the needs of the mother who was discharged but also through self-management and postpartum. In the future, we will conduct a study applying mothers and postpartum caregiver after approval of a clinical trail at a university hospital to evaluate developed healthcare services.

A hospital room has multiple patient monitoring devices at the bedside to monitor his or her status. However, vital sign monitors, ventilator and other bedside devices are made by a variety of different manufacturers and often cannot easily interface to the hospital information system. Medical environments incorporate complex and integrated data networks to transfer vast amounts of patient information, such as images, waveforms, and other forms of digital data. Hence, to assure interoperability of images, waveforms and patient data, Health Level Seven (HL7) was developed as an international standard to facilitate the communicating and storing of medical data. In this study, we developed middleware capable of receiving data from mCare 300 vital signs monitoring devices and converting the data to HL7 data format. The HL 7 middleware streamline clinical workflow and support patients. Therefore, clinical expertise are empowered to respond to dynamic healthcare situation as soon as they emerged, and consequently quality of care while helping to reduce the length of a patient's stay in a hospital.

For years, physicians and anatomists have been interested in the heart that has one functioning ventricle. Various terms have been suggested for this entity including single ventricle, common ventricle, double-inlet left ventricle, cor biatriatum triloculare, and primitive ventricle. In this report, the term "single ventricle" is utilized as suggested by Van Praagh, and is defined as that congenital cardiac anomaly in which a common or separate atrioventricular valves open into a ventricular chamber from which both great arterial trunks emerge. An outlet chamber, or infundibulum, may or may not be present and give rise to the origin of either of the great arteries. This definition excludes the entity of mitral and tricuspid atresia. An 11 year old cyanotic boy was admitted chief complaints of exertional dyspnea and frequent upper respiratory infection since 2 weeks after birth. He was diagnosed as inoperable cyanotic congenital heart disease, and remained without any corrective treatment up to his age of 11 year when he suffered from aggravation of symptoms and signs of congestive heart failure for 2 months before this admission. On 22nd of May 1979, he was admitted for total corrective operation under the impression of tricuspid atresia suggested by a pediatrician. Physical check revealed deep cyanosis with finger and toe clubbing, and grade V systolic ejection murmur with single second heart sound was audible at the left 3rd intercostal space. Development was moderate in height [135 cm] and weight[28Kg]. Routine lab findings were normal except increased hemoglobin [21.1gm%], hematocrit [64 %], and left axis deviation with left ventricular hypertrophy on EKG. Cardiac catheterization and angiography revealed 1-transposition of aorta, pulmonic valvular stenosis, double inlet of a single ventricle with d-loop, and normal atriovisceral relationship [Type III C solitus according to the classification of Van Praagh]. At operation, longitudinal incision at the outflow tract of right ventricle in between the right coronary artery and its branch [LAD from RCA] revealed high far anterior aortic valve which had fibrous continuity with mitral annulus, and pulmonic valve was stenotic up to 4 mm in diameter positioned posterolaterally to the aorta. Ventricular septum was totally defective, and one markedly hypertrophied moderator band originated from crista supraventricularis was connected down to the imaginary septum of the ventricular cavity as a pseudoseptum of the ventricle. Size of the defect was 3X3 cm2 in total. Patch closure of the defect with a Teflon felt of 3.5 x 4 cm2 was done with interrupted multiple sutures after cut off of the moderator band, which was resutured to the artificial septum after reconstruction of the ventricular septum. Pulmonic valvotomy was done from 4 mm to 11 mm in diameter thru another pulmonary arteriotomy incision, and right ventriculotomy wound was closed reconstructing the right ventricular outflow tract with pericardial autograft of 3 x 4 cm2. Atrial septal defect of 2 cm in diameter was closed with 3-0 Erdeck suture, and atrial wall was sutured also when rectal temperature reached from 24`C to 35.5`C. Complete A-V block was managed with temporary external pacemaker with a pacing rate of 110/min. thru myocardial wire, and arterial blood pressure of 80/50 mmHg was maintained with Isuprel or Dopamine dripping under the CVP of 25-cm saline. Consciousness was recovered one hour after the operation when his blood pressure reached 100 /70 mmHg, but vital signs were not stable, and bleeding from the pericardial drainage and complete anuria were persisted until his heart could not capture the pacemaker impulse, and patient died of low output syndrome 320 min after the operation.

Chloral hydrate와 hydroxizine을 이용한 경구진정법은 적용대상의 나이와 체중에 따라 제한을 받는다. 일반적으로 경구 진정법은 36개월 미만, 체중 15 kg 미만의 환아에서 가장 좋은 진정 효과를 보인다. 그러나 36개월 이상 또는 15 kg 이상의 환아에 대해서는 경구진정법이 적절한 진정 효과를 얻는데 한계를 가지며, 얕은진정으로 인해 시술 중 잦은 움직임을 보여 쉽게 진정에 실패하게 된다. 진정 실패 시 고려 할 수 있는 대안은 추가적인 약제 투여로 인한 재진정의 유도나, 좀 더 깊은진정 법으로의 전환이 있다. 그러나 깊은진정법으로의 전환은 환아의 움직임과 동통의 감소를 위해 흡입마취제 및 마취기계가 요구되어 외래 진료실에서는 쉽게 선택되지 못한다. EMLA cream(Eutectic Mixture of Local Anesthesia)은 피부의 도포마취를 위해 널리 사용되고 있는 약제로 본 증례에서는 이를 이용하여 자극 없이 정주진정 경로를 확보하여 경구진정에서 정주진정으로의 전환에 성공하였다. 만 46개월, 체중 15 kg 남아가 다발성 우식을 주소로 단국대학교 치과대학 병원 소아치과에 내원하였다. 일반적인 행동조절 하에 치료 권유하였으나 보호자의 요구에 의해 경구진정 시도하였으며, 경구진정 실패를 고려하여 복용 전 EMLA cream을 사전 도포하였다. 경구 복용 90분 경과 뒤에도 진정효과를 얻지 못하여 보호자의 동의하에 아산화질소를 이용하여 얕은진정 유도 후, EMLA cream 도포 부위에 정맥로를 확보하였다. 총 시술 시간 2시간 30분으로 특별한 부작용 없이 성공적으로 시술을 완료하였다.

Purpose: The field trauma triage for injured patients is essential for trauma care system. In this study, agreement of patient evaluation between by prehospital EMS personnel and by hospital staffs and the appropriateness of prehospital triage were evaluated. Methods: This observational study was conducted from September to October 2012 for 5 weeks. During this period, EMT evaluated patient's severity according to guideline for field triage and recorded. Same guideline was applied in 26 hospitals for patients with EMS use. Kappa statistics were used to measure agreement for each item of guideline. Finally, over-triage and under-triage rate of EMT were calculated. Results: During study period, total 3,106 patients were transferred to 26 hospital emergency departments with EMS use. Kappa statistics for "vital signs" items were 0.45 for mentality lower than V and 0.44 for systolic blood pressure lower than 90 mmHg as a moderate agreement. In "anatomy of injury" items Kappa statistics were very low. In "mechanism of injury" items Kappa statistics were 0.28 for high-rise fall down and 0.27 for high energy traffic accident but in other items Kappa statistics were very low. 362 patients (12.0%) were over-triaged and 281 patients (9.3%) were under-triaged. Conclusion: Field triage can be applied but need to evaluate and modify in order to become accurate and sensitive for decision of transportation.
