ABSTRACT

RFID technology meets identification and tracking requirements in healthcare environments with potential to speed up and increase reliability of involved processes. Due to this, high expectations for this integration have emerged, but hospital and medical centers interested in adoption of RFID technology require prior knowledge on how to squeeze RFID capabilities, real expectations and current challenges. In this paper, we show our lab tested solutions in two specific healthcare scenarios. On the one hand, we analyze the case of a medical equipment tracking system for healthcare facilities enabling both real-time location and theft prevention. Worth-noting aspects such as possible EMI interferences, technology selection and management of RFID data from hospital information system are analyzed. Lab testing of system reliability based on passive UHF RFID is provided for this case. On the other hand, we analyze and provide a solution for care and control of patients in a hospital based on passive HF RFID with the result of a fully functional demonstrator. Our prototype squeezes RFID features in order to provide a backup data source from patient's wristband. It also provides an offline working mode aiming to increase application reliability under network fail down and therefore, improving patient's safety. Considerations regarding lessons learned and challenges faced are exposed.

ABSTRACT

UNLABELLED: Hepatic cirrhosis is the leading cause of portal hypertension and is usually associated with the development ofsplacnic varices. Variceal intraabdominal rupture is a rare cause of hemoperitoneum. A case of spontaneous mesenteric vein rupture is reported. CLINICAL CASE: 43-year-old man with hepatic cirrhosis (Child-Pugh C stage) and previous bleeding of esophageal varices, admitted to hospital because of orthostatic hypotension episodes (positive tilt test) and abdominal distention. Laboratory: anemia, low platelet count and abnormal coagulation tests. CT scan showed abdominal fluid. Exploratory laparotomy was performed and 3 liters of blood were found into the abdominal cavity. The mesenteric vein had a ruptured variceal dilatation with intermitent jet bleeding. No organ abnormalities were found. Repair of the dilated vein was performed. The patient evolved well and was dismissed from hospital ten days after admittance. OBJECTIVE: To present a case in which a rare cause of intraabdominal bleeding, usually associated with high mortality rate, is follawed by a good clinical evolution.

ABSTRACT

La cirrosis hepática es la principal causa de hipertensión portal y se asocia con el desarrollo de venas esplácnicas varicosas. La rotura de várices intraabdominales es una causa rara de hemoperitoneo. Se presenta el caso de hemoperitoneo espontáneo por rotura de vena mesentérica superior varicosa. Caso clínico: varón de 43 años con antecedentes de cirrosis alcohólica (estadio C de Child-Pugh) y múltiples internaciones por hemorragia digestiva variceal. Consulta por episodios sincopales y distensión abdominal. Al examen físico se presento: vigil, orientado, hipotenso, con tilt test positivo, distensión abdominal, estigmas cutáneos de hepatopatía crónica. Laboratorio: anemia, plaquetopenia, rolongación de los tiempos de coagulación. TAC de abdomen: líquido libre en cavidad peritoneal. Laparotomía exploradora: se extraen tres litros de sangre de cavidad abdominal. Se visualiza vena mesentérica superior varicosa con una zona en forma de pezón que muestra punto de sangrado en jet, intermitente. No se evidenció daño de otro órgano. Se procedió a la rafia de la lesión lográndose hemostasia. El paciente evolucionó favorablemente abandonando el hospital 10 días después del ingreso. Objetivo: presentar un paciente con una causa poco común de hemoperitoneo y remarcar la buena evolución, ya que este tipo de patología suele tener alta mortalidad.
