Relación entre la saturación central venosa de oxígeno >_ 70% y la mortalidad en el choque séptico / Determination of the ratio of central venous oxygen saturation (ScvO2) > 70% mortality in septic shock. Patients admitted to pediatric intensive care unit

Objetivo: Determinar la Relación de la saturación central venosa de oxígeno (ScvO2) >_70% con la mortalidad, en el choque séptico en pacientes que ingresan al servicio de terapia intensiva pediátrica del HGR 36, Puebla. Métodos: Estudio, descriptivo, longitudinal, observacional. Se identificaron todos los pacientes de un mes a 14 años de edad que ingresaron a unidad de terapia intensiva con el diagnóstico de choque séptico. Se corroboró la colocación de un catéter venoso central para la medición de la ScvO2 a su ingreso y las 6 horas. Calificamos con el Indice Pediátrico de Mortalidad (PIM2) para medir el riesgo de mortalidad en cada paciente. Se realizó estadística descriptiva. Resultados: Fueron 15 pacientes, 8 (53.3%) femeninos y 7 (46.7%) masculinos. El PIM2 obtuvo un promedio de 7.42 % al ingreso, y a las 6 horas fue de 13.4%. El promedio de la saturación venosa central de oxígeno al ingreso de los pacientes a la terapia intensiva pediátrica fue de 56% y a las 6 horas el promedio alcanzó 71%. Ningún paciente falleció durante la reanimación cardiiopulmonar desde su ingreso. Conclusión: En base a los resultados anteriores podemos concluir, que no hay una correlación entre la ScvO2 >_ 70% y la mortalidad en los pacientes pediátricos con choque séptico

Objective: To determine the ratio of central venous oxygen saturation (ScvO2) >_ 70% mortality in septic shock patients admitted to pediatric intensive care unit of the HGR 36, Puebla. Methods: A descriptive, longitudinal, observational study. We identified all patients from one month to 14 years of age who were admitted to ICU with a diagnosis of septic shock. It confirmed the placement of a central venous atheter for the measurrement of income and ScvO2 to 6 hours. Qualified with the Pediatric Index of Mortality (PIM2) to measure the risk of death in each patient. We performed descriptive statistics. Results: there were 15 patients,eight (53.3%) female and 7 (46.7%) male. The PIM2 obtained an average of 7.42%. To entry, and 6 hours was 13.4%. The mean central venous oxygen saturation on admission of patients to the pediatric intensive care was 56% and 6 hours on average reached 71%. No patient died during cardiopulmonary resuscitation from your income. Conclusion: Based on previous results we can conclude that there is no coelation between ScvO2 >_70% and mortality in pediatric patients with septic shock

Spatially-resolved near-infrared spectroscopy for bedside monitoring of shock patients / 国际生物医学工程杂志

Objective To study the feasibility of non-invasive spatially-resolved near-infrared spectroscopy (SR-NIRS) in clinical bedside monitoring of shock.Methods The central venous blood samples of 25 patients with shock were collected and the central internal jugular central vein oxygenation (ScvO2) level was measured.The self-developed non-invasive SR-NIRS device was used to measure tissue blood oxygen saturation (StO2) surrounding the region of jugular central vein.In addition,the artery oxygen saturation (SaO2) and partial pressure of oxygen (PO2) were also measured using conventional methods.The correlation between StO2 between ScvO2,SaO2 and PO2 was analyzed.Results StO2 levels in shock patients were highly correlated with ScvO2 levels (r=0.84,P＜0.001) and the concordance coefficient of 0.80 was high.Conclusion StO2 value collected from the surrounding region of jugular central vein by SR-NIRS device can be used as an indicator of shock suggesting the potential of noninvasive SR-NIRS for bedside shock monitoring.
