Insights

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was common in infants hospitalized for serious bacterial infection (SBI) evaluation during high community spread. Most infected infants did not require intensive care.

Area of Science:

  • Pediatrics
  • Infectious Diseases
  • Epidemiology

Background:

  • Young infants hospitalized for serious bacterial infection (SBI) evaluations may be at risk for SARS-CoV-2 infection.
  • Understanding the prevalence and clinical characteristics of SARS-CoV-2 in this population is crucial for appropriate management.

Purpose of the Study:

  • To determine the prevalence of SARS-CoV-2 in infants under 90 days old hospitalized for SBI evaluation.
  • To characterize the clinical presentation of SARS-CoV-2 infection in these young infants.

Main Methods:

  • Retrospective chart review of infants <90 days old hospitalized for SBI evaluation.
  • Study conducted across 4 New York City inpatient facilities from March to December 2020.

Main Results:

  • 15% (22/148) of infants tested positive for SARS-CoV-2.
  • Infants admitted during high community SARS-CoV-2 circulation had a 31% positive rate, versus 3% during low circulation (P < .001).
  • Fever was the most common symptom (59%); SARS-CoV-2 positive infants were less likely to have positive cultures or require intensive care.

Conclusions:

  • SARS-CoV-2 was prevalent in young infants hospitalized for SBI evaluation during periods of high community transmission.
  • Clinical presentation often included isolated fever, and most did not require intensive care admission.

Acute Respiratory Failure-II

Type I Respiratory Failure, or hypoxemic respiratory failure, occurs when the partial pressure of oxygen (PaO2) in arterial blood falls below 60 mmHg while breathing room air without a corresponding increase in arterial carbon dioxide levels (PaCO2). This condition highlights a significant impairment in the lungs' capacity to oxygenate the blood.
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:

Acute Respiratory Failure-I01:21

Acute Respiratory Failure-I

Acute respiratory failure is a condition characterized by the inability of the lungs to perform their primary function: gas exchange. This failure leads to insufficient oxygen levels (hypoxemia) in the blood, elevated carbon dioxide levels (hypercapnia), or both, causing critical impairment in organ function.
Definition: It is defined by specific criteria based on blood gas measurements. Hypoxemia happens when the partial pressure of oxygen (PaO2) falls below 60 mmHg. At the same time,...

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...

Acute Respiratory Failure-III

Hypercapnic respiratory failure, also known as Type 2 or ventilatory respiratory failure, is a severe condition characterized by the body's inability to effectively remove carbon dioxide (CO2) from the bloodstream. It leads to an arterial CO2 pressure (PaCO2) exceeding 45 mmHg and a blood pH above 7.35. This situation indicates that the body's ventilatory demand, or the ventilation needed to maintain normal PaCO2 levels, surpasses its supply or the maximum gas flow achievable without...

Acute Respiratory Failure-IV

Respiratory failure can manifest suddenly or gradually, characterized by a rapid decline in PaO2 and a rapid rise in PaCO2. This situation indicates a severe respiratory problem that may quickly become a life-threatening emergency. One of the early signs of hypoxemic Acute Respiratory Failure (ARF) is a change in mental status due to the brain's sensitivity to oxygen levels and changes in acid-base balance. Symptoms such as restlessness, confusion, and agitation suggest inadequate oxygen...
