Clean Environment

Part of Midwifery and Childbirth

Preventing infection during childbirth through environmental preparation and aseptic technique.

Why This Matters

Before the 19th century, women who gave birth in hospitals died of puerperal fever (childbed fever) at rates of 10-35%. Women who gave birth at home attended by midwives died at rates of 1-2%. The difference was not surgery or drugs — it was that hospital physicians moved directly from autopsies and infected patients to deliveries without washing their hands. Ignaz Semmelweis demonstrated in 1847 that mandatory handwashing reduced hospital mortality from 18% to under 2%.

The lesson is stark: cleanliness, not medication, is the primary intervention preventing maternal and neonatal deaths from infection. In a resource-scarce setting where antibiotics do not exist, the ability to create a clean environment for birth is not an optional refinement — it is the central skill.

Puerperal fever is caused by bacteria (primarily Group A Streptococcus, but also Staphylococcus, E. coli, and others) introduced into the uterus during delivery. Neonatal tetanus is caused by Clostridium tetani introduced through the umbilical cord. Both are preventable through strict cleanliness.

Defining Cleanliness Levels

Clean: Physically clean — free of visible soil, blood, debris. Achieved by washing with soap and water.

Disinfected: Reduced microbial count to safe levels. Achieved by boiling, bleach solution, or alcohol. Not sterile, but much safer than merely clean.

Sterile: Complete absence of living microorganisms. Requires autoclaving (pressure-steam sterilization) or equivalent. Not achievable in field conditions.

Goal for childbirth: Clean birth attendant hands (ideally disinfected), clean or disinfected instruments for cord care, clean delivery surface, clean cloths for the infant. True sterility is not achievable but is not required — clean and disinfected is sufficient to prevent the majority of infection.

Handwashing

The Semmelweis Protocol

This is the single most impactful action in preventing birth-related infection. Apply it without exception.

Required moments:

• Before any vaginal examination
• Before any contact with the birth canal during delivery
• Before handling the newborn
• After handling body fluids (blood, amniotic fluid, placenta)
• Between the mother and any other patient

Method:

1. Remove any rings, bracelets, or watch. Pathogens live under jewelry.
2. Wet hands to the wrists.
3. Apply soap — enough to lather all surfaces.
4. Scrub vigorously for 30 full seconds: palms, backs of hands, between fingers, under nails (use a nail brush or stick if available), wrists.
5. Rinse completely under clean running water.
6. Dry with a dedicated clean cloth — not shared, not a general-use rag.

Nail length: Short nails are essential. Long nails harbor pathogens and cause internal injury during examinations. Birth attendants must keep nails cut short.

When soap is unavailable: Use wood ash (alkaline — antimicrobial). Mix to a paste with water, scrub as above, rinse thoroughly. Improvised but meaningfully better than nothing.

Preparing the Birth Surface

The surface where the woman delivers and where the baby lands must be clean.

Process:

1. Remove all visible dirt and debris.
2. Wash the surface with soap and water if possible.
3. Cover with a clean cloth layer — at minimum a clean sheet, folded cloth, or any reasonably clean fabric.
4. Place a waterproof cover (oilskin, waxed cloth, broad leaves) beneath the clean cloth if available, to prevent soaking through.

The floor is acceptable. A clean cloth spread on a clean floor is entirely appropriate for delivery. The decisive factor is cleanliness, not furniture.

Instrument Disinfection

For Cord-Cutting Equipment

The cord-cutting blade and cord ties are the instruments most likely to introduce infection directly into the newborn’s circulation.

Boiling (most reliable): Submerge metal instruments in a pot of water. Bring to a full, rolling boil. Boil for 10 minutes. Remove with a clean cloth or stick — do not handle with bare hands. Allow to cool on a clean surface or in clean water. Do not place back on any surface before use.

Flame (field emergency): Pass a blade through a flame until it glows red-hot. Allow to cool in air before use. Effective for bacterial contamination. Less effective against heat-resistant spores.

Alcohol (if available): Submerge instrument in 70% alcohol for 10 minutes. Remove and allow to air dry before use.

Boiling cord ties: Cloth ties boiled for 10 minutes and allowed to cool in a covered clean container.

Do not use: Instruments that have not been disinfected. Rusty instruments. Instruments that have touched the ground or non-clean surfaces after disinfection.

For Other Instruments

Any instrument that enters the birth canal (hands, any equipment) should be clean and ideally disinfected. Vaginal examinations with unwashed hands introduce bacteria directly to the environment where the baby will be born.

Clean Water Supply

All water used for birth must be clean — boiled, or from a trusted clean source.

Water needed at delivery:

• For handwashing (most important use)
• For cleaning the perineum before and after delivery
• For rinsing the infant if soiled
• For making herbal preparations if used

Prepare clean water in advance — labor does not pause while water boils. Have at least 2 liters ready before active labor begins.

After Delivery: Continuing Infection Prevention

Cord stump care: Keep the umbilical cord stump dry and clean. Do not apply soil, dung, ash, oil, or wrapping to the stump — traditional practices of applying various substances to the cord stump are a primary route for neonatal tetanus infection. Clean (if dirty), then leave open to air. It will dry and fall off in 7-14 days.

Monitoring for infection (neonatal): Signs of cord infection: redness or swelling spreading from the base of the stump, discharge, fever, poor feeding. This is a medical emergency — neonatal sepsis progresses rapidly.

Monitoring for infection (maternal): Puerperal fever typically appears 24 hours to 5 days after delivery. Fever (above 38 degrees C), lower abdominal pain, foul-smelling lochia. Treat with available antimicrobials (garlic, thyme tea, echinacea) and support. Rest. Hydration.

Placenta disposal: The placenta contains significant blood and is a culture medium for bacteria. Bury it deeply or burn it — do not leave it exposed in the living area.

The Clean Hands Rule Is Absolute

There is no situation in which a birth attendant should perform a vaginal examination or assist delivery with unwashed hands. Even in an emergency, the 30-second handwash is non-negotiable. The infection risk from unwashed hands at delivery is not theoretical — it is the documented cause of millions of maternal deaths. Do not shortcut this step.
