Dextran 70 in prophylaxis of thromboembolic disease after surgery: a clinically oriented randomized double-blind trial.

A randomized double-blind trial of prophylaxis of thromboembolism in surgical patients judged by clinical morbidity has been completed. Altogether 831 patients over 40 years of age who underwent elective surgery of the stomach, biliary system, or colon received either dextran 70 or normal saline before the operation. Thirteen of the 435 patients on saline and three of the 396 on dextran developed pulmonary embolism. Eight of these 16 patients died of pulmonary embolism--seven in the saline group and one in the dextran group. As detected either clinically or by 125I-fibrinogen scanning the incidence of deep vein thrombosis was similar in the two groups. There was no increased incidence of excessive bleeding in patients on dextran though clinical impression suggested that some patients on dextran bled excessively. This trial showed that dextran 70 administered by intravenous drip during operation is effective in preventing pulmonary embolism and, in particular, reducing mortality from this cause. It seems to be as effective as subcutaneous heparin but is easier to administer and places less of a burden on nursing services.

Use of oxytocin and incidence of neonatal jaundice.

A retrospective controlled study using data from the Cardiff Births Survey examined a possible relation between oxytocin administration to induce or accelerate labour and the subsequent development of neonatal jaundice. Among 10 591 infants born in Cardiff between 1970 and 1972 the incidence of neonatal jaundice was higher in infants born after oxytocin administration than among others. Analysis by gestational age at delivery, birth weight, Apgar score, length of labour, sedative and analgesic therapy during labour, and suppression of lactation showed that this association held within all these categories except among small immature infants, who are at high risk of jaundice in any case.

Pulmonary disability in coal workers' pneumoconiosis.

Results from a correlation survey which compared radiological and physiological findings during life with detailed morbid anatomical findings in the lungs of 247 deceased miners and ex-miners with pneumoconiosis were used to assess the extent and significance of their pulmonary disability.Coal workers' pneumoconiosis usually caused progressive impairment of ventilation, which in the simple type of disease was not related to radiological category. In such cases the presence of emphysema was found to be a more important factor in determining the impairment of ventilation than the radiological category of simple pneumoconiosis.
