Peritoneal dialysis is a home-based therapy for patients with end-stage kidney disease. It is less efficient in removing solutes and fluid than haemodialysis but offers more flexibility and independence. Peritoneal transport characteristics affect the dialysis prescription. The timing of drug administration is independent of the dialysis process except for the administration of intraperitoneal antibiotics. Dose reductions should follow current recommendations for patients with kidney disease. Fluid overload is common in patients undergoing peritoneal dialysis. Residual kidney function can ameliorate this problem and needs to be preserved. Dialysis solutions with high glucose concentrations contribute to adverse metabolic effects. Peritoneal dialysis-related catheter complications and infections may require patients to transition to haemodialysis. Antifungal prophylaxis needs to be co-administered for the duration of antibiotic courses for any indication to reduce the risk of fungal peritonitis. Close communication with the patient's supervising dialysis unit is required.
Long-term hypertension control in the community significantly reduces cardiovascular risk. However, the benefit of controlling acute elevations of blood pressure in hospitalised patients is unclear. In-hospital elevations of blood pressure are relatively common and might not reflect poorly controlled blood pressure before admission. The measurement of blood pressure in hospital patients significantly differs from the best practice recommended for primary care and outpatients. Recent observational studies suggest that the pharmacological treatment of acute, asymptomatic, in-hospital elevations of blood pressure may have no benefit. However, it may increase the risk of in-hospital and post-discharge complications. Pending the development of robust inpatient measurement protocols, acute blood pressure elevations in hospitalised patients should not routinely require antihypertensive treatment in the absence of symptoms or acute end-organ damage. Rather, such elevations should facilitate follow-up of blood pressure and other cardiovascular risk factors after discharge.
