Indocyanine green liver function studies on women taking progestins.

ABSTRACT

The liver extraction of indocyanine green in concentrations of 0.2 mg./kg. and 0.5 mg./kg. in women taking oral contraceptive (norethindrone 2 mg. with mestranol 0.1 mg., and norethindrone 1 mg. with mestranol 0.05 mg.) is reported. No major alteration was noted in the hepatic function with the plasma concentrations of the dye employed. The probability of increased hepatic arterial flow or increased cardiac output due to norethindrone-mestranol combination is noted. The value of indocyanine green in the study of liver dysfunction is stated and its relative sensitivity at various concentrations is mentioned. The use of indocyanine green to predict early hepatic changes in toxemia of pregnancy, especially in those patients with excessive weight gain, is suggested.
