Infection Prevention in Newborns

Antenatal and preconception prevention

Protecting the unborn child from infectious agents begins long before birth. Chronologically, this process is divided into two crucial initial stages, whose objective is to prevent the transmission of pathogens from mother to fetus.

Preconception stage (family planning) The key objective at this stage is working with women at risk. Medical specialists must perform a comprehensive screening of the expectant mother for markers of intrauterine infections (IUI). It is critical that pathogen detection and appropriate therapy are completed strictly prior to conception.

Antenatal stage (pregnancy period) Throughout pregnancy, preventive measures shift into a phase of active monitoring and correction of the woman's condition. They include:

• Foci sanitation: Active detection and treatment of any chronic foci of infection, as well as prevention of acute infectious diseases.
• Protective regimen: Creating favorable working and living conditions for the pregnant woman, which directly affects the body's resistance.
• Monitoring: Careful and regular observation in an antenatal clinic. This allows physicians to detect any deviations from the normal course of pregnancy early and correct identified pathologies in a timely manner.

Intranatal phase: protection during childbirth

The period of childbirth (intranatal phase) is associated with high risks of fetal infection when passing through the birth canal and potential trauma. The basis of prevention at this stage is exclusively rational and careful management of labor.

To minimize the risk of trauma and transmission of infection, obstetric tactics require:

1. Limiting vaginal examinations: Each such examination increases the risk of ascending infection, so their number must be strictly regulated and justified.
2. Special attention to amniotic fluid: In premature rupture of membranes, the fetus, deprived of natural protection, becomes extremely vulnerable. Immediate selection of correct patient management tactics is required.
3. Justification of obstetric maneuvers: Any application of obstetric maneuvers must be used only according to strict indications to eliminate the risk of fetal tissue trauma, which can become a portal of entry for infection.

Prevention of nosocomial infections in neonatology

After birth, the infant faces a new threat — nosocomial (hospital-acquired) infections. To protect newborns in maternity hospitals and neonatal units, strict infection control is implemented.

• Sanitary and epidemiological regime: The basic, fundamental, and most effective method of containing nosocomial infections remains strict hand hygiene. Medical personnel are required to thoroughly wash and antiseptically treat their hands both before and after every contact with any newborn.
• Disposable consumables: In modern neonatology, the reuse of care items and instruments is unacceptable. Syringes, vascular catheters, endotracheal tubes, and diapers must be exclusively disposable.
• Natural nutrition: The most crucial factor in establishing the infant's own immunity is early breastfeeding initiation immediately after birth followed by exclusive breastfeeding.
