We provide the first complete biophysical study of surfactant by captive bubble surfactometry from a neonate with meconium-stained amniotic fluid under controlled whole body hypothermia. Surfactant function improves after 48 hours of hypothermia, as surfactant cholesterol decreases. These findings partially explain positive effect of hypothermia on respiratory outcomes during meconium aspiration syndrome. A larger study including several neonates with or without lung disease is being conducted to better define the effect of hypothermia on surfactant function.

Name: Therapeutic hypothermia and temperature management
Human lysophosphatidylcholine acyltransferase 1 (hLPCAT1) is a protein which helps produce surfactant in the fetal lung. We previously reported that levels of cell-free fetal mRNA for hLPCAT1 in amnio...
The objective of this study was to determine the effect, if any, of maternal body mass index (BMI) and amniotic fluid index (AFI) on the accuracy of sonographic estimated fetal weight (EFW) at 40 t...
Deep hypothermia for the operative correction of congenital cardiac lesions protects hypoperfused organs, mostly because of its effect on lowering metabolic demand and oxygen requirement. Deleterious ...
Inadvertent perioperative hypothermia (body core temperature
The immune cellular composition of amniotic fluid is poorly understood. Herein, we determined: 1) the immunophenotype of amniotic fluid immune cells during the second and third trimester in the absenc...
The purpose of this research project is to ascertain the effectiveness of plastic head covering in prevention of hypothermia. Hypothermia is defined by body temperature
Cardiac arrest is a sudden, unexpected loss of heart function. Therapeutic hypothermia, in which the body's temperature is lowered and maintained several degrees below normal for a period ...
The purpose of this trial is to determine if hypothermia (body cooling), administered very soon after a severe brain injury improves functional outcome. This pilot trial ended in July 2005...
The present study was designed to evaluate, in premature babies with RDS breathing spontaneously, the efficacy of combined treatment with nasal continuous positive airway pressure (CPAP) a...
The objective of this pilot study is to examine the feasibility and safety of performing a larger trial to assess outcomes following treatment of meconium aspiration syndrome with surfacta...
Abnormally low BODY TEMPERATURE that is intentionally induced in warm-blooded animals by artificial means. In humans, mild or moderate hypothermia has been used to reduce tissue damages, particularly after cardiac or spinal cord injuries and during subsequent surgeries.
A pulmonary surfactant associated protein that plays a role in alveolar stability by lowering the surface tension at the air-liquid interface. It is a membrane-bound protein that constitutes 1-2% of the pulmonary surfactant mass. Pulmonary surfactant-associated protein C is one of the most hydrophobic peptides yet isolated and contains an alpha-helical domain with a central poly-valine segment that binds to phospholipid bilayers.
A pulmonary surfactant associated-protein that plays an essential role in alveolar stability by lowering the surface tension at the air-liquid interface. Inherited deficiency of pulmonary surfactant-associated protein B is one cause of RESPIRATORY DISTRESS SYNDROME, NEWBORN.
Lower than normal body temperature, especially in warm-blooded animals; in man usually accidental or unintentional.
An abundant pulmonary surfactant-associated protein that binds to a variety of lung pathogens and enhances their opsinization and killing by phagocytic cells. Surfactant protein D contains a N-terminal collagen-like domain and a C-terminal lectin domain that are characteristic of members of the collectin family of proteins.
