ABSTRACT
Resumen Objetivo Evaluar el diagnóstico de la coagulación intravascular diseminada (CID) mediante el uso de la escala para CID asintomática («scoring for non-overt disseminated intravascular coagulation¼). Material y métodos Se realizó un estudio clínico, epidemiológico, ambispectivo, transversal, descriptivo, en un grupo de 84 pacientes que ingresaron a la Unidad de Cuidados Intensivos con diagnósticos relacionados con el embarazo, en un hospital de la Secretaría de Salud de la Ciudad de México, durante el periodo del 1 de enero de 2014 al 31 de mayo de 2017. Resultados De una muestra de 84 pacientes, 12.29% presentó un puntaje para CID; en el análisis estadístico y la relación, no se observaron diferencias estadísticamente significativas entre mujeres con CID presente y ausente (t = 0.978; p = 0.665); tampoco con la presencia positiva de tabaquismo (χ2 = 1.337; p = 0.210) o alcoholismo (χ2 = 0.652; p = 0.314). Predominó la edad de 17 a 37 años. Conclusiones El uso de una escala para el diagnóstico o tamizaje en pacientes obstétricas es un auxiliar para aquéllas que cursan con CID asintomática; la puntuación mayor a cinco puntos se asocia con la presencia de la enfermedad. Como tamizaje para mujeres con sangrado obstétrico, la escala identificó con mayor frecuencia la CID asintomática.
Abstract Objective To evaluate the diagnosis of disseminated intravascular coagulation (DIC) using a non-overt DIC score. Material and methods A clinical, epidemiological, ambispective, transversal, descriptive study was carried out in a group of 84 patients who entered the Intensive Care Unit with diagnoses related to pregnancy at the General Health Hospital of Mexico City during the period from January 1, 2014 to May 31, 2017. Results From a sample of 84 patients, 12.29% presented a scoring for DIC; in the statistical analysis and the relationship, no statistically significant difference was observed between women with present and absent DIC (t = 0.978; p = 0.665), neither with the positive presence of smoking ( χ2 = 1.337, p = 0.210) or alcoholism ( χ2 = 0.652, p = 0.314). We had a predominance of age from 17 to 37 years. Conclusions The use of a scale for diagnosis or screening in obstetric patients is an aid for those with non-overt DIC; a score greater than five points is associated with the presence of the disease. As screening for women with obstetric bleeding, the scale most frequently identified non-overt DIC.
Resumo Objetivo Avaliar o diagnóstico de coagulação intravascular disseminada utilizando a escala de coagulação intravascular disseminada (CIVD). Material e métodos Foi realizado um estudo clínico, epidemiológico, ambispectivo, transversal e descritivo em um grupo de 84 pacientes que foram admitidos na Unidade de Terapia Intensiva com diagnósticos relacionados à gravidez, na Secretaria de Saúde da Cidade do México, durante o período de 1o de janeiro de 2014 a 31 de maio de 2017. Resultados De uma amostra de 84 pacientes, 12.29% apresentaram uma pontuação para a CIVD, na análise estatística e na relação não foi observada diferença estatisticamente significativa entre as mulheres com CIVD presente e ausente (t = 0.978; p = 0.665), nem com a presença positiva de tabagismo (x2 = 1.337, p = 0.210) ou alcoolismo (x2 = 0.652, p = 0.314). Com predomínio de idade de 17 a 37 anos. Conclusões O uso de uma escala para diagnóstico ou triagem em pacientes obstétricas é um auxiliar para pacientes com CIVD que não se manifesta, uma pontuação maior a cinco está associada à presença da doença. Como rastreio para mulheres com sangramento obstétrico, a escala identificou com maior freqüência a CIVD não-manifestada.
ABSTRACT
The present study aimed to examine the change cold-induced vasodilation (CIVD) of finger between seven female alpine (AP group) and six female cross-country skiers (CC group) at different points in their training programs. The CIVD test was performed twice, once in spring period after ski-training, once in the summer period during physical-training.From the onset of ice-water immersion in each CIVD test, finger skin temperature in each group fell followed by an incline. Thereafter, finger skin temperature began to rise and fall in an attenuated fashion during ice-water immersion. The resistance index (RI) in summer (7.1±1.7) for AP group was significantly (P<0.01) higher than that in spring (4.6±1.1). However, that of CC group showed no difference between spring and summer.These results suggested that the physical training during summer period for AP group may influence on the improvement of CIVD.
ABSTRACT
We studied the effects of transcutaneous electrical nerve stimulation (TENS) of Baxie on local cold tolerance as an index of cold induced vasodilatation (CIVD). The subjects consisted of 22 healthy adult volunteers.<br>The skin temperature and skin blood flow in the middle finger were measured simultaneously before, during, and after immersing the finger in cold water. TENS at 1Hz with 100-V intensity was applied for 5 minutes before immersion of the finger.<br>Experiments were conducted with no stimulation and with TENS on the same subjects on different days.<br>The results revealed the following:<br>1. The minimum skin temperature and minimum skin blood flow during immersion of the finger in cold water were higher in the TENS group than in the control (no stimulation) group.<br>2. The maximum skin temperature, mean skin temperature, and increase and decrease of skin blood flow rate during immersion of the finger in cold water and in the rising phase of skin temperature were higher in the TENS group than in the control group.<br>3. The index of resistance to frostbite was higher in the TENS group than in the control group.<br>4. The number of fluctuations in skin temperature during immersion of the finger in cold water was significantly higher in the TENS group than in the control group.<br>5. The incidence of abnormal perception during immersion of the finger in cold water was lower in the TENS group than in the control group.<br>These results suggest that TENS enhances the local cold tolerance of fingers by suppressing SSA in the initial falling phase on skin temperature and increasing the motion of skin blood vessels in the rising phase of skin temperature.
ABSTRACT
We studied the effects of electro acupuncture stimulation of Baxie on local tolerance as an index of cold induced vasodilation (CIVD). The subjects consisted of 22 healthy adult volunteers. The skin temperature and skin blood flow in the middle finger were simultaneously examined before, during, and after immersion of the finger in cold water. Electroacupuncture stimulation at 1 Hz with a 66 to 100V intensity was performed for 5 minutes. Experiments of no stimulation and electroacupuncture stimulation were conducted on the same subject on different days.<br>The results revealed the following:<br>1. CIVD was caused by rapid increase of skin blood flow during immersion of the finger in cold water.<br>2. The minimum skin temperature, minimum skin blood flow, maximum skin blood flow, mean skin temperature in the rising phase of skin temperature, and the index of resistance to frostbite of the electroacupuncture stimulated group were higher than those of the unstilmulated group, and rates of skin temperature increase and decrease during immersion of the finger in cold water in the electroacupuncture stimulated group were significantly higher. These results show that electroacupuncture stimulation increases local cold tolerance in the finger.
