The Impact of Fluid Therapy Strategies on Nonoliguric Hyperkalemia in Extremely Low Birth Weight Infants

PURPOSE: The aim of this study was to characterize the changes in the incidence and clinical characteristics of nonoliguric hyperkalemia (NOHK), together with plasma potassium levels, according to the fluid therapy strategies for extremely low birth weight infants (ELBWIs) during the first few days of life. METHODS: This retrospective study enrolled ELBWIs. We analyzed the occurrence of NOHK, plasma potassium levels, other biochemical data, and fluid balances according to historically controlled strategies such as conventional limited-volume supply and low-dose calcium supplementation (P1), increased-volume supply and high-dose calcium supplementation (P2), and early aggressive nutrition (EAN) and high-dose calcium supplementation (P3). RESULTS: The incidence of NOHK and the plasma potassium levels in P2 (127 ELBWIs) were not different from those in P1 (39 ELBWIs). However, arrhythmia and fatality significantly decreased in P2 compared to those in P1. In P3 (68 ELBWIs), the incidence of NOHK after 24 h and the plasma potassium levels after 36 h of life were significantly reduced compared to those in P1 and P2. Neither arrhythmia nor fatality developed in P3. CONCLUSION: EAN combined with high-dose calcium supplementation could be a potential strategy for the prevention of NOHK along with consequent arrhythmia and fatality in ELBWIs.

Influences of Bushen Zhuanggu Granule on Contents of Sexual Hormones and Metabolism of Calcium and Phosphorous in Early Menopausal Women / 广州中医药大学学报

Objective To explore the influences of Bushen Zhuanggu Granule (BZG)on contents of sexual hormones and metabolism of calcium and phosphorous in early menopausal women.Methods One hundred and Twenty-two early menopausal women were allocated to two groups:Group A was treated with BZG and Group B with nylestriol.Serum contents of sexual hormones and indexes of calcium and phosphorous metabolism were observed before and after treatment.Results After six months of treatment,the contents of serum estradiol(E 2)and alkaline phosphatase(ALP)were increased and the ratio of urine calcium and creatinine(Ca/Cr)decreased(P 0.05).The contents of follicle stimulating hormone(FSH)and luternizing hormone(LH)were increased in Group A as compared with Group B(P
