CRRT uses diffusion (haemodialysis), convection (haemofiltration) or combines these two methods (heamodiafiltration) in order to achieve solute removal from the blood. Small molecular weight substances like potassium, urea and creatinine are efficiently removed through haemodialysis (Kellum, Mehta, Angus, Palevsky and Ronco, 2002, p.1858). For larger solute molecules, heamofiltration is the most efficient method of their removal in comparison with dialysis. In haemofiltration, filtration of plasma through the semi-permeable membrane is caused by hydrostatic pressure. In addition, solutes cross the membrane alongside the plasma which results in convective solute transport flowing in the same direction as water (Medve, Preda and Gondos, 2010, p. 104). Therefore, haemofiltration needs the use of replacement fluid to avert excessive removal of fluid, electrolyte depletion as well as iatrogenic acidosis. Since the plasma solute concentration is the same as that of the removed filtrate, concentration of the solutes in the blood plasma remaining need to be diluted using substitution fluid. The use of combined convective and diffusive clearance as well as haemofiltration is effective for removal of large and small molecular weight solutes (Joannidis and Oudemans-van Straaten, 2007, p. 219). Modalities The several modalities of CRRT available are continuous veno-venous haemodiafiltration (CVVHDF), continuous veno-venous haemofiltration (CVVH) and continuous veno-venous haemofiltration (CVVHD). In terms of solute clearance rate, CRRT is lower in comparison with IHD (Intermittent haemodialysis treatments). However, balance clearance within the 24 hr period that CRRT is undertaken is much higher. Moreover, fluid elimination during CRRT is much slower and requires continuous use of anticoagulants which risks bleeding (Uchino, Bellomo, Morimatsu, Morgera, et al. 2007, p. 1567). Continuous veno-venous haemodiafiltration (CVVHDF) There is counter-flow of blood and dialysis solution within the dialysis filter Blood flows at a speed of between 100 and 200ml/min Dialysis solution speed is between 1 and 2 l/h Optimisation of the ultrafiltration speed is dictated by convective transport of dissolved substances and volume loss. The removal of solutes is done simultaneously by both diffusion and convection Substitution fluid is used to replace lost fluid Continuous veno-venous haemofiltration (CVVH) Removal of solutes occurs via convective transport Ultrafiltrate which is produced must be replaced using a substitution solution Removal of ultrafiltrate may cause patient’s volume loss Continuous veno-venous haemofiltration (CVVHD) There is counter-flow of blood and dialysis solution within the dialysis filter Blood flows at a speed of between 100 and 200ml/min Dialysis solution speed is between 1 and 2 l/h The administration of fluid is not routine Solute removal occurs through diffusion Principles and Indications Membrane characteristics must be considered when choosing treatment modalities of CRRT. These characteristics include; biocompatibility, solute removal and water permeability (Fall and Szerlip, 2010, p. 583). In general, efficiency of small molecules in CRRT is largely depended on ...Download file to see next pagesRead More

Hormone Replacement Therapy and Breast Cancer

...Is There An Association Between Hormone Replacement Therapy And Breast Cancer Breast cancer is a hormone dependant malignancy. Carcinomabreast is the most frequent malignancy in women. The acquired mutation as a cause of malignancy has raised interests among investigators, and it has been postulated that gonadal hormones naturally play a significant role in proliferation of breast tissue in different phases of a woman's life, hence exogenous hormones would act as a promoter of this disease. In an attempt to find out the actual relationship of the hormones in development of breast cancer, there had been extensive researches on different hormonal instigators that might have played a role in...

Human Growth Hormone Replacement Therapy and Aging

...HGH Summary of theory Human growth hormone (HGH) has been in use for a relatively short amount of time, so there is still a lot of lively debate inpeer reviewed journals about its possible uses and misuses. One factor upon which HGH has a debated effect is age or longevity. On the one hand, when it is given to some clients, HGH can promote growth and fight some of the effects of aging; on the other hand, it is not as useful the older the person taking it is, and there are other limiting factors. “Growth hormone is clearly our master hormone because of its ability to affect all other hormones, organs and the cells of our body. It has truly amazing reparative and restorative powers that can reverse cellular and tissue damage... Summary of...

Recommending alternative treatment for patients with hormone deficiency Hormone replacement therapy is a viable way of treating hormone deficiency but it has significant side effects. I can recommend herbal treatment for hormone deficiency because they help make up for the shortcomings of hormone supplements. Besides herbal hormone supplements, I can recommend certain foods that help treat hormone deficiency such as head vegetables and broccoli. These foods are a good alternative to hormone supplements because they are cheap and easily accessible. I can recommend physical exercise and relaxation techniques as...

Lastly, technology is increasingly enabling more women to access abortion services virtually, especially though video conferencing with physicians who can advise when abortion is necessary and the available options and dispatch them online. In addition, abnormality screening devices may increase abortion where it diagnoses conditions which cannot be corrected on the baby such as mental retardation or material injury to the spine (Sadati et al, 2014). However, positive outcomes of the screenings of unborn baby may reduce chances of abortion, especially among married couples. References Kaygusuz, I., Simavli, S.A., Eser, A., Inegöl, G.
