Bed bath, oral care and hygiene of the dependent patient
- Procedure
A bed bath and oral care clean, comfort and let you check the skin; a clean mouth also prevents pneumonia.
What it is
Hygiene for a patient who cannot wash on their own includes the bed bath, perineal care, oral and denture care, and care of the hair, nails and feet. Besides cleaning and comforting, it is a key moment to assess the skin, pain, mood and behaviour. Oral care matters more than it seems: hospital-acquired pneumonia in patients who are not ventilated is common, and regular toothbrushing reduces its risk. Privacy, body warmth and the patient's preferences are respected.
Indications
- Patients who cannot wash on their own because of pain, weakness, bed rest, or cognitive or physical impairment.
- Oral care for every inpatient, with extra care for those who take nothing by mouth or are at risk of aspiration.
- Skin assessment at every bath.
Contraindications and precautions
- Unstable patient or severe pain: the nurse gives or supervises the bath, and it may be postponed.
- Aspiration risk: leave no liquid in the mouth; head of bed raised or side-lying and suction ready.
- Warm, not hot, water: the patient tests it with their hand if able; fragile skin in older adults.
- Fall risk in the shower or when moving the patient: brakes, side rails and dry floors.
- Respect movement restrictions, drains, tubes and IV lines.
Equipment
- Basin, warm water, mild soap, towels, washcloths and bath blanket.
- Clean bed linen and gown, gloves and a bag for soiled linen.
- Soft (or suction) toothbrush, toothpaste, rinse and a labelled denture cup.
- Suction equipment if there is aspiration risk.
Step by step (and why)
- Identify, explain, ask preferences and give privacy — respects dignity and encourages cooperation.
- Hand hygiene, gloves if there is contact with body fluids, bed at working height and locked — protects patient and you.
- Test the water temperature and cover the patient with the blanket, uncovering only the area you wash — avoids burns and chill.
- Wash head to toe, clean to dirty, and dry the skin folds well — avoids spreading germs and maceration.
- Turn the patient as one unit to wash the back and check sacrum, heels and folds — this is the moment to assess the skin.
- Do perineal care last, front to back, and change gloves with hand hygiene — reduces the risk of infection.
- Brush teeth, gums and tongue; with aspiration risk, side-lying or sitting and with suction — prevents pneumonia.
- Clean dentures outside the mouth and store them in a labelled cup — avoids loss and infection.
- Leave clean clothes, the bed low and locked and the call bell in reach; record the skin and findings — gives safety and continuity.
Complications
- Falls during the bath or shower.
- Burns from water that is too hot.
- Chilling, especially in older adults.
- Aspiration during oral care in patients with dysphagia.
- Skin injury from friction or from poorly dried skin folds.
Next step: when to call for help
- Report red skin that does not blanch, wounds, blisters, bruises or rashes.
- Report mouth sores, bleeding gums, pain or changes in swallowing.
- Report if the patient coughs, chokes or changes colour during oral care.
- Report pain, persistent odour, discharge or changes in behaviour noticed during the bath.
Test yourself
Think of the answer, then tap the question to see it.
In what order is the patient washed in a bed bath?
Head to toe, from cleanest to dirtiest, with the perineal area last, followed by a glove change and hand hygiene.
Why is oral care important in patients who take nothing by mouth?
Because a dirty mouth favours hospital-acquired pneumonia. Brushing at least twice a day reduces that risk.
How is oral care given to a patient at risk of aspiration?
Sitting up or side-lying, with a suction toothbrush or suctioning saliva before and after brushing, leaving no liquid in the mouth.
What can be assessed during a bed bath?
The skin (especially bony prominences and folds), pain, mood and behaviour, as well as any discharge or odour.
