Relationship between changes in blood pressure from summer to winter and estimated 24-hour salt excretion using spot urine: the Niigata Wellness Study.

A convenient way to determine salt intake is salt excretion using spot urine (e-NaCl). We measured e-NaCl at health checkups and compared results with seasonal changes in blood pressure. Among 19,732 examinees who underwent health checkups from Aug. 2012 to Mar. 2013, age, body weight and e-NaCl were measured and compared to monthly mean systolic blood pressure (SBP). Excluded were those taking antihypertensive drugs and with creatinine levels higher than 2.0 mg/dL. Also examined was salt intake (i-NaCl) by an interview survey from Aug. to Dec. 2012. Correlations with SBP were R = 0.7718 for age, R = 0.5996 for body weight, R = 0.2498 for i-NaCl and R = 0.9335 for e-NaCl. e-NaCl decreased in summer. It was presumed that the reduced burden on the kidney of salt excretion due to sweating may be related to decreases in blood pressure in summer.

Influence of nursing intervention on blood pressure change for patients with lithotomy position surgery / 中国实用护理杂志

ObjectiveTo investigate the effect of medical elastic bandage and passive lower limb movement on blood pressure changes for patients with lithotomy surgery. Methods300 cases of lithotomy surgery patients in our hospital were randomly divided into three groups with 100 cases in each group.Group A was taken with routine care as the control group.Group B was taken with the medical elastic bandage based upon routine care.Group C was given passive movement in the lower limb based upon routine care.The blood pressure changes for three groups of patients were compared. ResultsThe lower extremities flat blood pressure was significantly reduced for patients of group A.The average arterial blood pressure decreased significantly at the flat lower limb immediately and after 5 min.The changes were statistically significant compared with patients of group B and C. ConclusionsThe medical elastic bandages and lower limb passive motion play a role in stabilizing the blood pressure of patients with lithotomy position surgery,which is worthy of clinical promotion.
