Excessive fluid removal during dialysis can lead to hypotension, especially when combined with what type of medication?

Excessive fluid removal during dialysis can indeed lead to hypotension, and this risk is significantly heightened when combined with antihypertensive medications. Antihypertensives are designed to lower blood pressure, and when a patient undergoing dialysis already experiences fluid removal that drops blood pressure, introducing antihypertensive drugs amplifies that effect. This combination can result in dangerously low blood pressure levels, contributing to symptoms like dizziness, fainting, and even shock in severe cases.

In contrast, diuretics are often used to promote fluid elimination in patients with fluid retention but are not typically administered during dialysis procedures because dialysis itself serves to remove excess fluid. Anticoagulants are used to prevent blood clotting during dialysis and do not directly affect blood pressure but instead manage the risk of clot formation in the dialysis circuit. Vitamin supplements have no significant impact on blood pressure and are unrelated to fluid management during dialysis. Therefore, among all the options, antihypertensive medications present the most relevant risk when combined with excessive fluid removal during dialysis.
