The dialysis unit of Watford General Hospital was my designated placement for the one-week course.

A dialysis unit is mainly for people who have had kidney in the past and therefore their kidneys no longer do their prime function, which is filter, the blood. A typical patient has to receive dialysis treatment for four hours a day, three times a week. There are two types of ways that the dialysis treatment is administered either, through a neckline connection which is located just beneath the neck or on the underside of the lower arm. Many younger patients prefer to have the treatment in their arm as this way the tube connecting them comes out every time they have finished the treatment. Whereas the neckline patients have a permanently fixed tube attached to their chest, which prevents them from doing such activities as swimming.

The age range for this treatment varies between 28 - 80 +, the treatment is usually lifelong and very frustrating. The only other option to dialysis treatment is a transplant but a kidney has to be donated from a blood relative. However even if the transplant is successful the patient still needs to undergo two to three months of dialysis treatment in order to get the kidney functioning in its new body. But if the operation fails it then becomes a danger to the patient and would result in going back to stage one, which is dialysis treatment.

A dialysis machine is around five feet high by two feet wide. The cables and tubes that connect the machine to the patient are looped in a circle around the machine and connected to the corresponding places. On the left-hand side of the machine, a long glass tube is filled with the patient’s blood and the filtration begins from there. The patient’s blood is taken through the machine and purified, just as a functioning kidney would do. The process usually takes around fours hours to complete.

There were several dangers to this treatment but in the past century technology has evolved to a certain point that the treatment is now concerned to be one of the safest there is. The dialysis machine has several built in alarms, which notify the ward staff if there are any problems. For example if any air got into the blood of the patient then it could cause a serious problem and could potentially be fatal, if this problem occurs the dialysis machine automatically shuts off the pump and traps the blood, while sounding an alarm which notifies the staff.
