Insights

Nearly one in four very premature infants without bronchopulmonary dysplasia were readmitted, with respiratory infections being a major cause. Respiratory syncytial virus (RSV) infections significantly contributed to these readmissions in infants not receiving RSV prophylaxis.

Area of Science:

  • Neonatal Medicine
  • Pediatric Pulmonology
  • Infectious Diseases

Background:

  • Very premature infants face significant respiratory morbidity post-discharge.
  • Lower respiratory tract illness (LRTI) is a common cause of readmission in this vulnerable population.
  • Respiratory syncytial virus (RSV) is a primary pathogen responsible for severe LRTI in neonates.

Purpose of the Study:

  • To determine the incidence and risk factors for readmission due to any LRTI and RSV-documented LRTI.
  • To evaluate the impact of RSV prophylaxis on readmission rates in very premature infants.
  • To identify specific risk factors associated with readmission for respiratory illnesses.

Main Methods:

  • A multicenter prospective longitudinal cohort study involving 2813 infants born before 33 weeks of gestational age.
  • Infants were followed through the respiratory epidemic season.
  • Data collected included gestational age, bronchopulmonary dysplasia status, intrauterine growth restriction, and RSV prophylaxis use.

Main Results:

  • Among infants without bronchopulmonary dysplasia and not receiving prophylaxis, 15.1% were readmitted for LRTI and 7.2% for RSV-related LRTI.
  • Infants born before 31 weeks' gestation, with intrauterine growth restriction, or from single-mother families had higher readmission risks.
  • For infants receiving prophylaxis, 6.1% were readmitted for RSV-related LRTI.

Conclusions:

  • A significant proportion of very premature infants without bronchopulmonary dysplasia are readmitted, with LRTI and RSV infections being key contributors.
  • Gestational age, intrauterine growth restriction, and family structure are associated with increased readmission risk.
  • Further research is needed to understand the role of other respiratory pathogens in post-discharge morbidity.

Breathing01:05

Breathing

The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...

Transmission-based Precautions II: Airborne and Protective Environment

Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...
Pulmonary Cycle: Exhalation01:17

Pulmonary Cycle: Exhalation

In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

Pneumonia V: Nursing management and Prevention

Nursing management of pneumonia involves promoting airway patency, facilitating rest and conserving energy, encouraging fluid intake, maintaining nutrition, and educating patients.
The nurse must practice strict medical asepsis and adhere to infection control guidelines to minimize healthcare-associated infections.
Enhance airway patency
Position the patient correctly to facilitate drainage of the affected lung segments. Manual or mechanical percussion and vibration can also be employed.
Acute Respiratory Failure-V01:29

Acute Respiratory Failure-V

The treatment for acute respiratory failure varies based on factors like the underlying cause, overall health, and severity. A collaborative healthcare team is essential for early detection, often through arterial blood gas analysis. Identifying the cause is the primary goal, with treatment strategies adjusted for ventilation/perfusion (V/Q) mismatch, shunting, or diffusion impairment.
Ensure that patients are monitored continuously for their response to therapy, including changes in...
Respiratory Syncytial Virus Disease01:29

Respiratory Syncytial Virus Disease

Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
