Evaluación del efecto de la terapia de relajación en pacientes con hipertensión arterial

ObjectivesTo evaluate whether the application of a relaxation therapy reduces the blood pressure in hypertensive patients and whether there is improvement in several parameters which can influence blood pressure such as anxiety, quality of life and sleep.MethodsA quasi-experimental study (measures before-after) was performed in 25 Primary Care patients with hypertension poorly controlled by pharmacological treatment. The intervention consisted of relaxation therapy composed of 3 techniques: passive relaxation of Schwartz-Haynes, diaphragmatic breathing and imaginary visualization. A total of 14 group sessions of 30 min each (2/week) were conducted. Systolic and diastolic blood pressure were taken at the beginning and end of the relaxation programme implemented and after each of the programme sessions. The Pittsburgh Sleep Quality, Quality of Life Hypertension, State-Trait Anxiety and Perceived Stress questionnaires were used to measure psychosocial parameters.ResultsAfter intervention, a reduction in systolic blood pressure of 20 mmHg (p < .001) and of 8 mmHg (p < .001) in diastolic blood pressure was observed. Regarding other factors, sleep quality (p < .001), quality of life (p< .001) and state anxiety (p = .004) were significantly improved.ConclusionsRelaxation therapy had positive effects in improving blood pressure parameters, as well as the other factors evaluated. In our opinion, such strategies should be evaluated more thoroughly to consider their inclusion in Primary Care.     

Valoración en la variación de la composición corporal del enfermo crítico

Critically ill patients are especially prone to malnutrition because their hypermetabolic state produces an increase in nutritional requirements that often are not covered with the formulae supplied. Evaluation of the body composition (BC) makes it possible to quantify the main structural components of the body: muscle, bone and fat. An anthropometry study was made for the assessment of these elements to obtain information on the protein-calorie nutritional status of critically ill patients. We have aimed to describe the variations in the BC of the critical ill patient during the first seven days after ICU admission. The observational study included 50 critically ill patients, of whom 78% were male and 22% women with a mean age of 56 years.Height, weight, body mass index (BMI), bone diameters, muscle perimeters and skinfolds of patients were recorded. The body composition (BC) calculations were performed using the Faulkner, Rocha, Wurch and Matiegka formulae. We obtained the baseline energy expenditure of each patient with the Harris-Benedict formula. After analyzing the data, a decrease was found in the percentage of muscle mass (mean ± SD: 3 ± 0.76), an increase in the percentage of body fat (2 ± 0.76) and an increase in BMI at the expense of an augment of weight. We have concluded that during the first week of ICU admission patients lose critical muscle mass and have an increase in fat mass. Awareness of these changes in the BC of patients may be useful to determine the appropriate nutrition for critically ill patients.
