Kidneyfailure is the medical condition where the kidneys fail to filter themetabolic wastes from the blood sufficiently. In that regard, chronickidney disease (CKD) also regarded as chronic renal disease entailsthe progressive loss of kidney functionality over several months oryears. It is a long-term condition that is sometimes related to oldage. This paper will discuss the different types of dialyses and themost effective one in the management of this disease. The extent ofthe ailment is determined by the symptoms that can be severe. Some ofthem include tiredness, swollen hands, feet, or ankles, blood inurine, and shortness of breath. Before discussing the different typesof dialyses, it is important to comprehend the stages, causes, andsymptoms of the disease.
Symptoms,Causes, Tests, and Treatment of CKD
Inthe early stages, CKD is rarely detected. This is because the bodycan cope with the considerable reduction in the functions of thekidney. It can only be noticed through regular checks. However,during the later stages, a victim may experience reduced appetitethat leads to weight loss, swollen hands, feet, and ankles,tiredness, and shortness of breath. The patient also suffers fromitchy skin, headaches, muscle cramps, insomnia, increased rates ofurination, and blood in urine. It also leads to erectile dysfunctionin males. At this stage, the ailment is regarded as kidney failureand may require transplantation or dialysis [CITATION NHS16 p 1 l 1033 ].
Thecauses of CKD are varying and can be a combination of severalproblems. It can be due to high blood pressure, diabetes, highcholesterol, infections, glomerulonephritis, regular usage of somemedicines, obstructions of urine flow, and polycystic kidney ailmentthat can be inheritable. As such, the illness can be avoided througha healthy lifestyle. The common diagnosis mechanisms include urineand blood tests [CITATION NHS16 p 1 l 1033 ].The examinations are used to identify if certain substances arehighly concentrated in the kidney. Presently, CKD has no cure.However, some treatment methods can be utilized to relieve or stopthe symptoms. The type of therapy is dependent on the severity of theailment. The core management practices include alteration of thelifestyle, medications to control issues like high cholesterol orhigh blood pressure, kidney transplant, and dialysis. Dialysis is themechanism where kidney functions are replicated in the body[CITATION NHS16 p 1 l 1033 ].
Stagesof Chronic Kidney Disease
Phase1-2 (early stage). Some individuals at this stage show no symptoms.As such, management mainly targets controlling the blood pressure aswell as healthy lifestyles. The middle stage (phase 3-4) entails thediscovery of the ailment. This is because of the increase of wastesin the blood. Control at this step focuses on slowing down theprogress of the illness to lessen other complications. Stage 5 isregarded as the end phase, and the only remedy is a kidney transplantor dialysis [CITATION Web161 p 1 l 1033 ].
ChronicKidney Disease Dialysis
Dialysisis the process of removing waste products as well as excessive fluidsfrom the blood during kidney failures. The procedure is instigatedwhen the kidneys cease working properly. It often entails divertingblood to a device that cleans it. Therefore, it operates like akidney to filter the blood and remove hazardous wastes as well asexcessive fluids that are passed out of the body as urine [CITATION Med162 p 1 l 1033 ].The procedure can be temporal or eternal depending on the severity ofthe ailment. In other words, when a patient is awaiting transplant,dialysis is done. On the other hand, if the patient cannot undergo anoperation, he/she needs the procedure for eternity. However, in someinstances, patients suffer temporal kidney issues and once they arehealed the process is stopped. There are two common types of dialysisi.e. hemodialysis and peritoneal dialysis[CITATION Med162 p 1 l 1033 ].
Inthis procedure, a physician creates an entry into one of the bloodvessels to join the body to a filtering machine. This is known asvascular access. At this part, blood can be removed and returned withease. The method entails driving the victim’s blood via anarrangement of semipermeable tissues i.e. “artificial kidney”that divides the blood from the dialysate. This is a solution ofcrystalloids such as calcium, bicarbonate buffer, and sodium [CITATION Kid161 p 15 l 1033 ].Osmotic interchange across the tissues permits the extraction ofphosphate, creatinine, and urea among other uremic metabolites. Itallows for the modification of electrolyte and acidosisabnormalities. Regulation of the pressure variances through themembrane permits convective water loss as well as the dissolvedsolutes coming from the blood section. This necessitates the volumeoverload corrections. The management needs sufficient entree to theperson’s circulation, normally through the creation of anartificial graft or arteriovenous fistula. Theprocess may temporarily enter by the Hickman catheter or subclavian.These accessing elements are referred to as the victim’s“lifeline.” Hemodialysis normally happens for three times a week,with each session lasting from 3 to 6 hours depending on thepatient’s size and compliance to dietary. Some patients withrecurring renal failure operation are managed twice a weekeffectively, although it does not work for the majority [CITATION Kid161 p 16 l 1033 ].
ComplicationsRelated to Hemodialysis
Duringrenal failure, the capacity to defecate liquid loads is absent orreduced in the patient. Fluid equilibrium is controlled throughextraction of the same in dialysis together with water and sodiumrestriction. Non-acquiescence with any can result in volume overloadthat acts the same manner as a heart failure, with pulmonary andperipheral edema. Fluid exhaustion is not common but might betriggered by over-vigorous extraction of fluid in dialysis. It mayalso emanate from vomiting or intercurrent diarrhea [CITATION Kid161 p 22 l 1033 ].
ThoughErythropoietin shortage is the main reason, in hemodialysis aperson’s iron insufficiency can contribute because of constant lossof small amounts of blood in the dialyzer. Oral Iron enhancementsare, therefore, necessary. Apart from that, they can be offeredintravenously during dialysis. During this procedure, a patient maylose some folic acid contributing to anemia. However, this is onlyprevalent in patients who have dietary issues. After hematinicshortage is corrected and the other reasons for anemia are removed,treatment is achieved via subcutaneous epoetin. It can also be giventhrough darbepoetin, which is long acting [CITATION Kid161 p 23 l 1033 ].
Bloodpressure remains high in some patients in spite of sufficient fluidextraction. These patient need antihypertensive treatment.Hyperkalemia can grow because of the destruction ofaldosterone-reliant colonic emission of potassium via ACE inhibitors.Other complications include vascular calcification, neuropathy, bone,joint, and cardiac diseases [CITATION Kid161 p 24 l 1033 ].
Asoft tube, known as a catheter, is put inside the belly. Theprocedure is done surgically, and the catheter enables the connectionto a distinct tubing which permits two to three quarts of a purgativefluid to drift into the belly [CITATION Kid16 p 15 l 1033 ].The cleansing fluid is referred to as the dialysate. This fluid cantake roughly 10 minutes to feel the stomach. Once the filling iscomplete, the catheter must be capped to ensure it does not leak. Theperitoneal membrane works as a natural filter. It allows the surplusfluids in the blood to flow through to the cleansing sample. Also,the lining prevents the vital aspects such as the nutrients and redblood cells from flowing out[CITATION Kid16 p 15 l 1033 ].
Forthe task to be completed efficiently, the dialysate has to remain inthe stomach for more than two hours contingent to the body size andthe waste to be extracted. When the dialysate is within theperitoneal cavity, it performs the task of a reservoir containing thedialysis solution [CITATION Kid16 p 17 l 1033 ].The waste materials move from the bloodstream through the peritonealtissues and into the dialysate. When the time is up, the dialysateused together with the blood impurities are drained from the cavityand substituted by fresh solutions[CITATION Kid16 p 17 l 1033 ].
Thecentral PD sequence involves drain, fill, and dwell. An exchangeoccurs every time the sequence is repeated. In the first phase,drain the tube is connected to the PD set while the old dialysate isremoved. These happen within four to eight hours [CITATION Kid16 p 19 l 1033 ].The next step is fill a fresh dialysate is placed in the peritonealcavity. The third stage is dwell, where the bags and tubing aredisconnected. The dialysate stays in the cavity for a certain amountof time. During this phase, extra fluids and wastes are extractedfrom the blood vessels through the peritoneal membrane. At thebeginning of the exchanges, the catheter must be connected to atubing set. Only a small extension of the tube and the catheter arevisible during the exchanges. The set is placed on the tummy. Thereare two types of PD i.e. Continuous Ambulatory Peritoneal andAutomated Peritoneal[CITATION Kid16 p 20 l 1033 ].
Effectsof PD on the Body
ThroughoutPD process, a typical adult easily holds two to three liters ofdialysis solution within the peritoneal cavity. Though it appears tobe a significant amount, there is little to no discomfort to thepatient. While the fluid penetrates through the membrane, the waistswells slightly [CITATION Nat15 p 1 l 1033 ].Though a patient may feel the change, it diminishes with time.However, the amount is much smaller for the children. As such, itmust be tailored to their sizes. The peritoneal catheter is about30cm long and stays permanently on the body. The exit point which isthe area where the peritoneal catheter leaves the abdomen must alwaysbe cleaned to avoid infections. This mechanism heightens the chancesto get infections along the lining of the belly. Apart from that, theprocess may be tedious to some patients[CITATION Nat15 p 1 l 1033 ].
Choosingbetween the two types is rather intricate since each one of them hasits own merits and demerits. Nonetheless, major variances occur whenselecting between a home based procedure and an in-center dialysis.Making the right choice is dependent on the severity of the ailment.However, the home-based peritoneal dialysis is the most suitable forthe majority of the patients. In this method, the patient needs tovisit the health care facility twice a month for laboratory work. Itis much better than the in-center type, where a patient has to visitthe facility thrice a week. PD is also convenient since it can bedone at home while traveling, or at work. As such, the patient can betaught how to use the equipment and serve themselves. It reduces theamount of time required to visit the facilities.
