Hemodialysis and peritoneal dialysis are medical choices used to deal with end-stage renal illness. Regardless of their similarities, they’re removed from being alike. This text explains the marked variations between these two medical phrases.



Hemodialysis, also called dialysis or kidney dialysis, is a medical process used to purify the blood by means of a dialyzer, a machine that features as an “synthetic kidney”. The tip-goal of the purification course of is to revive the electrolyte stability inside the physique regardless of the kidney’s incapability to operate optimally.

A remedy choice for folks affected by kidney failure, hemodialysis removes extra fluid and waste merchandise akin to urea, free water, and creatinine from the bloodstream. It may possibly both be an inpatient or an outpatient remedy choice.

Peritoneal dialysis

Peritoneal dialysis can also be used to deal with kidney failure. On this process, the tissues within the affected person’s belly cavity are used to filter the blood and take away extra fluids and waste merchandise. This dialysis approach goals to right electrolyte imbalance by eliminating toxins from the bloodstream.

Through the process, a dialysis catheter is surgically inserted into the belly cavity, the place a particular fluid is flushed to scrub and cleanse the intestines. After a particular time frame, the fluid containing waste merchandise is faraway from the peritoneal cavity.

Usually, the answer used through the course of is a mix of hydrogen carbonate, chloride, sodium, and an osmotic agent. The intestinal partitions operate as a filter between the bloodstream and this particular answer.

Hemodialysis vs Peritoneal Dialysis

So what’s the distinction between hemodialysis and peritoneal dialysis? Whereas each these medical procedures have the identical end-goal, they enormously differ in a lot of methods.

Firstly, hemodialysis makes use of a dialyzer, a man-made membrane that removes extra fluids and waste merchandise to filter the bloodstream. Peritoneal dialysis, then again, makes use of the peritoneal membrane (the liner of the belly cavity) of the affected person, together with a dialysate (a cleaning agent) to attain the identical end-result.

Earlier than hemodialysis initiates, a registered doctor must create an insertion web site to facilitate unimpeded blood stream out and in of the physique. The perfect entry websites embrace the suitable inside jugular vein, the suitable exterior jugular vein, the left inside jugular vein, or the left exterior jugular vein. In the meantime, throughout a peritoneal dialysis, an entry is created to the affected person’s belly cavity.

In relation to this, hemodialysis requires needle insertion to a vein because the dialyzer is related to the physique by way of tubes hooked up to the affected person’s blood vessels. Opposite to this, peritoneal dialysis doesn’t require needle insertion because the cleaning agent is launched into the belly cavity by way of a dialysis catheter.

When it comes to size and frequency, a hemodialysis process lasts for roughly 3 hours. It’s usually achieved thrice every week, relying on the doctor’s prescription. Peritoneal dialysis, then again, is named an “change.” A affected person present process this remedy is really helpful to finish round 4 to six exchanges a day.

Moreover, hemodialysis often requires help from knowledgeable healthcare supplier, whereas peritoneal dialysis promotes independence as it may be achieved by the affected person alone. Plus, since equipment is used for hemodialysis, it is more difficult to set it up at house.

Lastly, by way of dangers, hemodialysis makes a affected person extra susceptible to bloodstream an infection, whereas peritoneal dialysis heightens a affected person’s threat for peritonitis, an an infection of the liner of the belly cavity.
