Sin embargo, a pesar de las guías actuales, el tiempo de ayuno supera frecuentemente las 12 horas antes de un procedimiento electivo. Objetivos: Describir los efectos del ayuno en el estado hídrico, gasto urinario y volúmenes plasmático y sanguíneo; evidenciados por cambios en el peso, hematocrito y volumen urinario. Métodos: Se realizó un estudio prospectivo cuasiexperimental sin grupo control; se llevaron 18 sujetos (10 hombres, 8 mujeres) a un punto de hipohidratación leve por medio de ayuno absoluto de sólidos y líquidos en un periodo máximo de 24 horas; se midió el peso y el gasto urinario de manera seriada y se tomaron muestras sanguíneas al comienzo y al final del periodo de ayuno. Resultados: Se encontró un déficit hídrico de 16 ml/Kg tras 12 horas de ayuno y una pérdida de 1,038 g/Kg/h en adelante. El tiempo medio para llegar a la hipohidratación fue de 15:09 horas (±3,3h); los sujetos presentaron un descenso del gasto urinario a un promedio de 0,6 ml/Kg/h y se calculó una reducción de los volúmenes sanguíneo y plasmático de 2,9% y 4,18% respectivamente. Conclusiones: El ayuno prolongado como aquel que se presenta antes de un procedimiento quirúrgico puede provocar hipohidratación y oliguria. Esto podría afectar la respuesta ante el reto anestésico y quirúrgico; aumentando la susceptibilidad de complicaciones renales, hemodinámicas, entre otras. Se sugiere que las instituciones tomen medidas que eviten tiempos excesivos de ayuno y las complicaciones relacionadas (Texto tomado de la fuente).Background: Preoperative fasting attempts to reduce aspiration risk during anesthesia; despite current recommendations, fasting time frequently exceeds 12 hours before elective procedures. Objectives: To describe the effects of fasting in hydration status, urinary output, plasma and blood volume; through the measuring of weight loss and changes in hematocrit and spontaneous void of the bladder. Methods: A quasi-experimental, uncontrolled, prospective study was conceived; eighteen subjects (10 male, 8 female) were taken to a mild hypohydration (defined as a water deficit equal to 2% of bodyweight) through fasting in a maximum period of 24 hours; subjects were weighted, and their urine output was measured repeatedly throughout the trial. Blood samples were drawn before and after this fasting period. Results: After 12 hours of fasting, subjects had a water deficit of 16 ml/Kg on average, with an ongoing loss of 1,038 g/Kg/h from there on. A mean time to hypohydration of 15:09 hours (±3,3h) was calculated. Moreover, a decline was observed in urinary output, plasma and blood volumes at the time of hypohydration; median urinary output fell to 0,6 ml/Kg/h, meanwhile blood volume and plasma volume decreased by 2,9% and 4,18% respectively. Conclusions: Prolonged fasting akin to that required before surgical procedures can result in hypohydration and oliguria. These may affect the system’s response to surgical stress and anesthesia management; increasing the risk of renal and hemodynamic complications, amongst others. Institutions ought to address long preoperative fasting and related complications.MaestríaMagister en FisiologíaSe realizó un estudio prospectivo cuasiexperimental sin grupo control; se llevaron 18 sujetos (10 hombres, 8 mujeres) a un punto de hipohidratación leve por medio de ayuno absoluto de sólidos y líquidos en un periodo máximo de 24 horas; se midió el peso y el gasto urinario de manera seriada y se tomaron muestras sanguíneas al comienzo y al final del periodo de ayuno.xvii, 95 páginasapplication/pdfspaUniversidad Nacional de ColombiaBogotá - Medicina - Maestría en FisiologíaFacultad de MedicinaBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá610 - Medicina y salud::612 - Fisiología humanaHematócritoPeso CorporalVolumen PlasmáticoHematocritBody WeightPlasma VolumeAyunoEstado de hipohidratación del organismoDeshidrataciónPeriodo preoperatorioOliguriaFastingOrganism hypohydration statusDehydrationPreoperative periodOliguriaAyuno e Hipohidratación en un Periodo de 24 horas, Estudio Piloto Cuasiexperimental en Condiciones Naturales en Voluntarios en BogotáFasting And Hypohydration in A Period Of 24 Hours, A Quasi-Experimental Pilot in Natural Conditions in Volunteers In BogotáTrabajo de grado - Maestríainfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/acceptedVersionTexthttp://purl.org/redcol/resource_type/TMBogotáColombiaRomit JJA, van de Mortel T.
