The persistence of dextran 70 in blood plasma following its infusion, during surgery, for prophylaxis against thromboembolism.
An infusion of dextran (mean molecular weight 70000) in normal saline (either 1 litre or 500 ml) was given to patients undergoing hysterectomy. The infusion was started at induction of anaesthesia and continued throughout the operation and for up to 5 h thereafter. The rate of elimination of dextran was independent of the dose given. The time to eliminate half the dose was nearly two days and up to 10% was still present in the circulation after one week. The persistence of dextran in the plasma in these amounts and for this length of time may have considerable implications in the prophylaxis of postoperative deep venous thrombosis.
