The influence of body position on pulmonary function in low birthweight babies.

The influence of the prone and supine body positions on the respiratory rate, arterial pH, pO2, pCO2 and serum bicarbonate level; on alveolar pO2 and pCO2; and on alveolar/arterial gradients for carbon dioxide and oxygen, were compared in 10 low birthweight infants. THE ALveolar pCO2 was higher in the prone, while pO2 was higher in the supine position, possibly as a result of ventilation/perfusion imbalance with increased physiological dead space in the supine position. There were no significant differences between the other parameters studied. Since aspiration of feed by the low birthweight infant is a major cause of morbidity and mortality, evidence is presented in favour of the prone nursing position.

Screening for abnormal haemoglobins: a pilot study.

A pilot study has been made of the implication of screening for abnormal haemoglobins in immigrant schoolchildren. An abnormality was detected by capillary blood haemoglobin electrophoresis in 8.4% of 6,835 children and a haemoglobinopathy outpatient clinic had to be established to deal with the heavy work load which resulted. The clinic was also used to determine the value of investigating the remaining members of the family once an abnormality had been detected in one child.Healthy siblings with normal haemoglobin electrophoretic patterns and normal iron and folate levels were studied to determine a normal range for haemoglobin in relation to age for adequately nourished immigrant children. The lower limit of the normal range was close to the mean value minus 1(1/2) S.D.; by using this definition 10.3% of 280 children were subsequently found to be anaemic.Population screening of this type is desirable, but further pilot studies of patient education, genetic counselling, organization of specimen collection, data processing, and follow-up health care facilities are required before screening is extended more widely in the United Kingdom.
