Summary

Nosocomial infections are the primary transmission route in neonatal intensive care units (NICUs), affecting 15-20% of infants. Current infection control strategies are ineffective, necessitating novel approaches to reduce risks and boost neonate immunity.

Area of Science:

  • Neonatal Intensive Care Unit (NICU) infections
  • Nosocomial infection epidemiology
  • Neonatal infectious diseases

Background:

  • Nosocomial infections are the predominant transmission route in NICUs, with infection rates mirroring adult ICUs.
  • Significant risk factors include indwelling vascular catheters, hyperalimentation, assisted ventilation, and prior antibiotic use.
  • Existing prophylactic strategies (antibiotics, immunoglobulins, physical barriers) have proven unsuccessful in reducing NICU infections.

Purpose of the Study:

  • To highlight the high prevalence of nosocomial infections in NICUs.
  • To identify key risk factors associated with these infections.
  • To underscore the urgent need for new infection prevention and neonate resistance-enhancing methods.

Main Methods:

  • Review of surveillance studies on NICU infection rates.
  • Analysis of identified risk factors for nosocomial infections in neonates.
  • Evaluation of the efficacy of current infection control strategies.

Main Results:

  • NICU infection rates range from 15% to 20%, comparable to adult ICUs.
  • Vascular catheters, high-calorie infusions, ventilation, and prior antibiotics are significant risk factors.
  • Prophylactic measures have failed to effectively decrease infection rates.

Conclusions:

  • Nosocomial infections pose a major threat in NICUs.
  • Current interventions are insufficient to control infection spread.
  • Development of novel strategies to mitigate risk factors and enhance neonatal immunity is critical.
