Introduction. The transition of glucose into the blood during automated peritoneal dialysis with regeneration of the dialysis fluid leads to a decreased removal of excess fluid from the body and corresponding violations of the water-salt balance.Aim. To consider a system for automatically maintaining the concentration of glucose in the dialysate solution, which provides effective ultrafiltration, as well as to propose a non-contact photometric feedback sensor.Materials and methods. The sensor is an optical system of an IR laser diode with a power of 30 mW and a wavelength of 1600 nm, a photodiode and a quartz tube, through which the test solution circulates. The sensor measures the attenuation of the radiation passing through the solution in a pulsed mode and calculates the glucose concentration. The selected combination of digital filters provides compensation for the noise of the optical system. Experimental studies of the efficiency of the sensor were carried out on peritoneal dialysis solutions with various concentrations of urea, creatinine, uric acid and glucose. At the beginning of the experiments, the sensor was calibrated in a pure solution.Results. It was shown that the developed sensor makes it possible to measure the concentration of glucose in a solution for peritoneal dialysis in the range of 42…220 mmol / l with a relative error of about 15%. The time of one measurement is about 1 minute, which makes it possible to obtain up-to-date information on the current concentration of the solution.Conclusion. This combination of characteristics will allow the sensor to be used in artificial kidney wearable devices for assessing the glucose content in the solution, calculating the time to change the solution and as a feedback sensor in a system for maintaining the concentration of the osmotic agent.

Abstract A method has been developed for the determination of arsenic (As) in pharmaceutical and scalp hair samples of kidney failure patients by cloud point extraction (CPE). The scalp hair samples were subjected to microwave-assisted digestion in nitric acid–hydrogen peroxide (2 + 1, v/v). Then, dialysate and digested scalp hair solutions were preconcentrated by CPE using pyronine B as a complexing agent. The resulting complex was entrapped in nonionic surfactant (Triton X-114) prior to its determination by electrothermal atomic absorption spectroscopy. The validity of the CPE method for As was checked by analysis of a certified reference material of human hair and a standard addition method for dialysate solution. The chemical variables affecting the analytical performance of the CPE methods were studied and optimized. After optimization of the complexation and extraction conditions, a preconcentration factor of 52 was obtained for As in 10 mL of dialysate solution and acid digested samples of scalp hair. Under the optimum experimental conditions, the LOD and LOQ of As for the preconcentration of 10 mL of solution were 0.022 and 0.073 μg/L, respectively. The level of As in scalp hair samples of kidney failure patients was higher than in healthy controls.

Electrolyte Replacement

Hydrofluoric acid (HF), a dangerous inorganic acid, is widely used in various industries and in daily life. Chemical burns caused by HF exposure occur more frequently in some regions worldwide. It has been reported that some cases with HF burns can be lethal due to the hypertoxicity of HF. In this article, we present a case of a 24-year-old worker who suffered HF burns by 53% HF solution to his face, neck, and nasal cavity. This patient quickly developed electrolyte disturbance, that is, hypocalcemia, and hypopotassemia, and myocardial injury after exposure. Multiple measures had been taken to treat this patient, including fluid resuscitation, electrolyte replacement, timely wound treatment with neutralizers, and respiratory tract care. Moreover, continuous renal replacement therapy was also employed to remove fluoride in the circulatory system and rectify the electrolyte disturbance and acid-base imbalance. The patient smoothly pulled though and survived. High fluoride levels in the dialysate solution were confirmed, indicating that continuous renal replacement therapy is an effective and potentially lifesaving treatment for acute HF poisoning.

To allow a better adsorption performance inside a novel magnetic adsorption device designed in the process of hemodialysis, the mechanical properties of magnetic absorbents trapped inside a two-phase system are studied in this paper. A gradient magnetic coil field was assumed to produce the magnetic driving force that balances other hydraulic forces for the adsorbents. Applying this field, a complement practical form of winding equation for the solenoid coil is obtained. The case studies are also made in this paper to explore the design of the field.

Many patients tolerate peritoneal dialysis well and experience little difficulty with the process. There are, however, a number of unique complications that can arise in a patient undergoing peritoneal dialysis. While infection remains a significant concern, there are also many non-infectious problems that can occur. Many mechanical complications occur as a result of the increased intra-abdominal pressure associated with the instillation of fluid into the peritoneal cavity. The dialysate solution itself may also play a role in some of the metabolic complications seen. An awareness of the potential problems that can occur will help the clinician in properly caring for a patient on this therapy and this chapter describes a range of non-infectious complications that may arise.
