Abstract
Our own random clinical observations suggested that premature infants with respiratory distress syndrome (RDS) have larger umbilical cords (UC) than term infants and prematures without RDS. That UC size might distinguish RDS susceptible prematures from prematures with prenatal stress sufficient to produce pulmonary biochemical maturation (no RDS), was prospectively studied. Over a 3-month period, UC's were examined on all admissions to Univ. Hosp. San Diego, Nursery. Weight, displacement volume, and largest diameter of ends and middle of a 10cm. UC segment were measured. Results are tabulated.
Although premature UC's are larger than term UC's there is no difference in UC size of prematures with and without RDS.
