“…found no change in hepatic blood flow in 12 women during early‐ (1.71 L/min at 12–14 weeks), mid‐ (1.92 L/min at 24–26 weeks), and late‐pregnancy (1.80 L/min at 36–38 weeks) compared to 1.81 L/min at 10–12 weeks postpartum using indocyanine green. Last, Probst et al . found that hepatic blood flow was decreased to 70% of the control value during labor in seven healthy pregnant women compared with nonpregnant controls.…”

The pharmacokinetics of many drugs are altered by pregnancy. Drug distribution and protein binding are changed by pregnancy. While some drug metabolizing enzymes have an apparent increase in activity, others have an apparent decrease in activity. Not only is drug metabolism affected by pregnancy, but renal filtration is also increased. In addition, pregnancy alters the apparent activities of multiple drug transporters resulting in changes in the net renal secretion of drugs.

To establish current practice patterns and assess the general knowledge among vitreoretinaltrained physicians regarding the use of indocyanine green (ICG) angiography during pregnancy, and to review the literature regarding the established safety of ICG angiography in pregnant women. Methods: A survey was mailed to 1101 members of the Retina, Macula, and Vitreous Societies. Results: Of the 520 respondents, 434 (83%) had seen at least 1 pregnant woman who required ICG angiography or fluorescein angiography. Of these, 385 (89%) withheld fluorescein angiography and 105 (24%) withheld ICG angiography, largely because of fear of teratogenicity or lawsuit. Diabetic retinopathy and choroidal neovascular membrane were the most common indications

Applications of in vivo near‐infrared (NIR) spectroscopy have emerged in various segments of clinical medicine and medical research. Developments in photonics, wireless connectivity, and smart devices that have been spurred on by the communication revolution have set the stage for even more rapid advancement of noninvasive or minimally invasive medical applications of NIR spectroscopy. The goal of this article is to review the current capabilities and limitations of in vivo NIR spectroscopy and highlight the impact of these capabilities and limitations in selected areas where NIR spectroscopy is being used to address clinical problems. The optical properties of tissues are briefly reviewed as these properties largely dictate the feasibility of an in vivo spectroscopic diagnostic approach and constrain the scope of problems that can be tackled using NIR spectroscopy. Some of the more successful applications of NIR spectroscopy in medicine are described. The number and magnitude of confounding factors that confuse in vivo spectroscopy can be daunting to the experimentalist and may represent the largest barrier in transforming in vivo spectroscopic measurements into clinically meaningful and reliable information. In vivo NIR spectroscopy abounds with opportunity and challenge.
