“…In general, the acid–base status can be determined from the blood pH, which is kept in a narrow range of 7.36–7.44 by a number of buffer systems, the lungs, and the kidneys (23). Disturbances of the acid–base-balance are characterized by a pH of <7.36 (acidosis) or >7.44 (alkalosis) and can be either due to respiratory or metabolic disorders (24, 25). To identify whether a disturbance is of respiratory or metabolic nature, not only blood pH but also the pCO 2 as a marker for respiratory disorders, and the concentration of bicarbonate as well as BE, as a marker for metabolic disorders, should be measured (26–29).…”

BackgroundThe ‘Western diet’ typically consumed in industrialized countries is characterized by high amounts of processed cereal grains and animal products while being low in vegetables, tubers, and fruits. This dietary behavior leads to imbalances of acid–base status in favor of the acids and may cause low-grade metabolic acidosis (LGMA) that is associated with negative effects on health in the long run, including urolithiasis, bone loss, and even cardiometabolic diseases. Therefore, it has become of great interest to find dietary strategies that can be used to neutralize the acid load associated with Western diets.ObjectiveThe aim of this study was to investigate whether the diet-dependent net acid load can be reduced by the daily consumption of mineral waters with different bicarbonate content and different potential renal acid load (PRAL).MethodsA single-centered, randomized trial including 129 healthy men and women aged from 18 to 75 years was conducted. Participants consumed 1,500–2,000 mL of one of four mineral waters with different bicarbonate content and different PRAL values daily for 4 weeks: low bicarbonate, high PRAL (LBHP, HCO3−: 403.0 mg/L, PRAL: 10.7); medium-high bicarbonate, medium PRAL (MBMP, HCO3− : 1816.0 mg/L, PRAL: −10.8); high bicarbonate, low PRAL (HBLP, HCO3−: 2451.0 mg/L, PRAL: −19.3); medium-high bicarbonate, low PRAL (MBLP, HCO3−: 1846.0 mg/L, PRAL: −22.1). Throughout the study, participants were asked to maintain their usual dietary habits. The primary outcome was the net acid excretion (NAE) measured in the 24-h urine output.ResultsConsumption of the three mineral waters: MBMP, HBLP, and MBLP led to a significant decrease in NAE values. Within the MBMP group, the NAE could be reduced by 48% (P = 0.001), while consumption of HBLP led to a reduction of 68% (P < 0.001) and MBLP to a reduction of 53% (P = 0.001). Moreover, a slight increase in serum bicarbonate could also be observed in the groups that drank HBLP (P = 0.057) and MBLP (P = 0.001).ConclusionDaily consumption of at least 1,500–2,000 mL of mineral water rich in bicarbonate (>1800.0 mg/L) with medium or low PRAL (<−11 mEq/L) can effectively reduce the NAE level by reducing the dietary acid load under free-living conditions in healthy adults.

Background: Arterial blood puncture is one of the most complex parts of nursing practice. Purpose: Evaluate effect of applying program based learning on nurse's performance and self-efficacy regarding arterial blood puncture. Method: Quasi experimental research design has been utilized in this study. This study was conducted at four hospitals affiliated to ministry of health. A convenient sample of 70 nurses was included. Three tools were utilized for collecting data; first tool was a questionnaire to assess nurses' knowledge regarding arterial blood puncture. Second tool was observational checklist of arterial blood puncture procedure. The last one was arterial blood puncture self-efficacy scale. Results: the study results revealed improvement in nurses' knowledge and practice regarding arterial blood puncture after applying the program based learning. A significant difference was founded between levels of nurses' self-efficacy about arterial puncture after program implementation with p-value of 0.000. While, hospitals where nurses working are associated significantly with total self-efficacy of nurses regarding arterial blood puncture. Conclusion: the current study concluded that the program based learning about arterial puncture improves nurses' knowledge, practice and self-efficacy. Additionally, regular training program regarding arterial blood puncture should be applied in hospitals. Conducting the same study in larger sample is recommended.

“…En la fase pre-analítica está la mayor probabilidad de introducir errores en la prueba, sin embargo, es la menos estudiada (2) . En ella, la trazabilidad en los datos de identificación del paciente (3) , la calidad de las jeringas (4) , el tipo de anticoagulante usado (5) , la temperatura de transporte de la muestra (agua helada a 4°C) (6) , temperatura del paciente (7) y el tiempo de almacenamiento entre la toma de la muestra y su procesamiento (6) son entre otros, factores determinantes en la calidad de los resultados; de ahí la importancia de su estandarización y control permanente.…”

“…Según varios estudios internacionales, la proporción de estos errores es significante (6,8) . Por otra parte, en la mayoría de los hospitales, las muestras de sangre se toman mediante el uso de jeringas de plástico de polipropileno de alta densidad (impermeables a los gases) (7) . El equipo de extracción de sangre adecuado para los estudios de gases sanguíneos es la jeringa plástica heparinizada (8) .…”

“…Los equipos miden generalmente el pH, la PO2 y el PCO2 a 37°C. Por lo tanto, los pacientes con temperatura corporal de 37°C o cercana a esta, tendrán resultados exactos que corresponden a los intervalos de referencia, mientras que los pacientes febriles o extremadamente hipotérmicos pueden tener resultados que difieren marcadamente de la verdadera concentración in vivo (7,12) .…”

Introducción: Varios factores pre-analíticos afectan los resultados de gases sanguíneos. Objetivo: Evaluar la calidad del proceso pre-analítico de los análisis de gasometría sanguínea solicitados en las unidades de cuidados críticos e intermedios de una institución hospitalaria de tercer nivel de la ciudad de Santiago de Cali. Materiales y métodos: Estudio descriptivo/transversal. Se evaluaron las solicitudes y muestras tomadas a pacientes hospitalizados en las unidades de cuidados críticos. Se calculó medidas de tendencia central, desviación estándar y distribución de proporciones. Los test de Medianas y Kruskal-Wallis permitieron evaluar diferencias estadísticamente significativas en el manejo de la muestra por unidad de servicio/turno/mes/semana de estudio. El análisis se realizó en STATA 15®. Resultados: La muestra efectiva fue de 414 tomadas a 125 pacientes. En promedio se tomaron 4 muestras/día para estudios de gasometría. El 100% de las solicitudes y muestras no cumplieron con los criterios de calidad y seguridad para la identificación del paciente y 3% cumplieron con los criterios técnicos de temperatura y tiempos. Conclusiones: Las directrices del Ministerio de Salud para la seguridad del paciente y las normas técnicas de calidad pre-analítica en gasometría no se cumplen.
