The Medical Uses of Water

Medical Surgeon

Water has many uses as a tool in the medical field, being used to prepare food for medical patients and to sterilise materials for procedures. It plays a very important part in the health care field, being used for washing surgical equipment, as well as for hydrotherapy for patients. Water prevents the risk of infection when treating ill patients and ensures cleanliness, and assists in finding cures for patients and new diseases. It can be used in treating people with body dysfunctions, to minimise the risk of infection and controlling the bacteria that enters their body.


Medical Instruments

Equipment used during surgery needs to be sterilised and cleaned. Therefore, water helps to sterilise instruments, preventing deposits, spotting and residue being left on them. This prevents infection and cross-contamination. Water is always used in cleaning, once disinfectants have been used, water rinses away chemicals and leaves surfaces germ free. It can also be a good way to wipe off screens and avoid leaving streaks. It ensures that medical equipment that is in contact with human skin is sterilised.



Water is regularly used by surgeons for decontaminating their hands and arms before they perform surgery. This prevents bacteria from getting on the skin and contamination surgeries or equipment. A scrub station is usually where surgeons decontaminate and scrub clean their hands and arms before rinsing.


Surgeon Washing Hands



Sterile water is frequently used to clean wounds as it is pure and can help prevent infection. The pure form of water has no impurities, avoiding infecting or contaminating wounds.


First Aid

If you get injured, it is good to have a bottle of water close by. This is because the water helps to clean the area of the wound and prevent infection or bacteria spreading to the rest of the body.



Dentists regularly use water, especially during operations following a tooth extraction or root canal treatment. They rinse your mouth out with sterile water, washing away existing bacteria.


Dentist Surgery


Autoclave Chamber

These are also known as steam sterilisers and are used in healthcare clinics, dentists and industrial applications. It uses steam under pressure to kill harmful bacteria, viruses and fungi that are placed inside the pressure vessel. This prevents bacteria from infecting and contaminating areas or patients.


Veterinary Surgeries

Veterinarians use water regularly for operations and sanitisation, as well as for intravenous injections. These are commonly given to pets to reduce fevers and keep them hydrated.


Lab Experiments

Water is regularly used for experiments, as water impurities can ruin lab experiments and is used for cleaning tools. This makes sure contaminants or minerals don’t taint laboratory results.



This involves the surgeons dispersing water into the surgical field to have a complete visualisation of an area. It consists of antibodies mixed with water and is put into the body cavity.


Continuous Positive Airway Pressure (CPAP) Machines

Water is used in these devices; this machine is a lifesaver who people who suffer from sleep apnea. The machine takes air and pressurises it, therefore when the person breathes through the attached mask, the airway is kept open. They also have a water tank that helps add moisture to the air. It also helps prevent bacteria and stops the machine from having mineral deposit build-ups.


Dialysis Machines

If you have damaged kidneys then you may be put on a dialysis machine, this works as an artificial kidney. It uses water to filter out bad toxins from your blood, allowing you to have cleaner blood for your kidneys function.



Facilities for renal replacement therapy that carry out hemodialysis have a large water demand. It is regularly used in maintenance dialysis facilities for reuse on the same patient.


Automated Endoscope Reprocessor (AER)

An endoscope is a medical instrument that is used to examine interior surfaces on the body. Water is used to rinse fluid in the device, and requires regularly cleaning and disinfecting when being used on patients.



Water creates a soothing environment for patients who undergo hydrotherapy and is used in hydrotherapy tanks. Hydrotherapy uses water to soothe pains and treat certain medical conditions. This includes pools, whirlpools, whirlpool spas, hot tubs and physiotherapy tanks. Medical conditions such as burns, septic ulcers, arthritis, lesions and amputations are improved by sitting in warm water. This water needs to be clean as these patients have weakened immune systems. They are also easily vulnerable to new infections from contaminated water.
