Meningitis and encephalitis: droplet precautions, neuro checks, comfort and contacts
- Safe practice
Suspected bacterial meningitis is an emergency: treatment starts at once, droplet precautions protect others, and close contacts are found quickly.
What it is
Bacterial meningitis kills about one in six people who get it, and one in five survivors has lasting harm such as hearing loss, seizures or weakness. Antibiotics start as soon as it is suspected, and nothing (not even the lumbar puncture) should delay the first dose. Meningococcal disease can kill within hours, and a fast-spreading purple or red rash that does not fade with pressure is a sign of very severe illness. Nursing care covers four things: rapid recognition and escalation, transmission precautions (droplet for meningococcus and Haemophilus influenzae type b until 24 hours of effective treatment; standard for most other causes, including viral meningitis and most encephalitis), close neuro checks for rising intracranial pressure and seizures, and helping public health identify the close contacts who need preventive treatment. In Colombia, the Ministry of Health guidance (2018) sets out droplet isolation and contact prophylaxis.
What it requires
- Droplet precautions: single room or more than a metre from other patients, surgical mask within a metre or for any procedure, hand hygiene, gown and gloves if splashes are likely, mask on the patient for transport.
- Health workers need preventive treatment only if they had direct contact with the patient's respiratory secretions (for example, mouth-to-mouth or intubation without a mask).
- In children, late signs of meningococcal disease (confusion, falling consciousness) appear 15 to 24 hours after the first symptoms; the rash can be harder to see on dark skin (check palms, soles, conjunctiva, palate).
- Possible after-effects: hearing loss, seizures, limb weakness, vision, speech and memory problems, scarring or amputation after sepsis.
How it is applied (and why)
- Recognise the signs and call at once: treatment must start without delay, even before the lumbar puncture.
- Start droplet precautions as soon as bacterial meningitis is suspected and post the sign: meningococcus spreads in respiratory droplets.
- Collect the ordered samples, never delaying the first antibiotic dose: the antibiotic comes first.
- Do neuro checks and vital signs at the ordered interval: falling consciousness, seizures or a pupil change mean rising pressure.
- Check the skin, palms and soles for a rash and recheck it: a spreading rash means sepsis.
- Keep seizure precautions ready and the airway clear: seizures can occur.
- Help comfort: control fever and pain as prescribed and adjust light and noise per protocol, because light sensitivity and headache are common.
- Report the case as the institution's surveillance protocol requires and help list close contacts: they need prophylaxis quickly.
- Explain the isolation to the patient and family, and report any change in hearing: hearing loss is a frequent after-effect.
In nursing practice
- Call at once: falling level of consciousness, a seizure, a pupil change, a new or spreading rash, cold hands and feet, fast breathing, low blood pressure.
- Isolation ends 24 hours after effective treatment starts for meningococcus and Haemophilus influenzae type b, not when the fever goes.
- Prevention: vaccines against meningococcus, pneumococcus and Haemophilus influenzae type b give the best protection; Hib is in most national childhood schedules.
- Encephalitis carried by mosquitoes or ticks needs standard precautions; in endemic areas, screens and repellents protect others.
Common mistakes
- Waiting for the lumbar puncture or the culture result before the first antibiotic dose.
- Using droplet precautions for every meningitis, or for none: the cause decides.
- Ending isolation when the patient looks better rather than after 24 hours of effective treatment.
- Forgetting to tell the team about a colleague who did airway care without a mask.
Test yourself
Think of the answer, then tap the question to see it.
Which precautions are used for suspected meningococcal meningitis, and for how long?
Standard plus droplet precautions, until 24 hours after effective antibiotic treatment starts.
Should the first antibiotic dose wait for the lumbar puncture?
No. Antibiotics start as soon as bacterial meningitis is suspected; the lumbar puncture must never delay the first dose.
Which health workers need preventive treatment after caring for a patient with meningococcal disease?
Only those with direct contact with respiratory secretions, such as mouth-to-mouth resuscitation or intubation without a mask.
What does a non-fading rash that spreads quickly mean?
Very severe meningococcal disease with sepsis. Call at once; the patient can deteriorate within hours.
