Comparative Study
Relative humidity under radiant warmers: influence of humidifier and ambient relative humidity.
The effects of humidifier air temperature and flow, and ambient relative humidity (RH(amb)) on RH and air temperature under a radiant warmer (RW) were determined in stable and unstable conditions, using an infant surrogate. Mean supplemented RH under the RW was 36.3% at 14% RH(amb) and 67.6% at 55% RH(amb). ⋯ S. hospital, and could be predicted by calendar date (r = 0.58). Humidification equipment capabilities and limitations must be known when using this method to limit evaporative water loss.

Case Reports
Reversible oligohydramnios in a pregnancy with angiotensin-converting enzyme inhibitor exposure.
The use of angiotensin-converting enzyme inhibitors during pregnancy has been associated with poor fetal outcomes, including oligohydramnios, renal tubular dysplasia, cranial malformations, and fetal death. A 35-year-old woman with chronic hypertension was treated with the angiotensin-converting enzyme inhibitor benazepril until 27 weeks' gestation, when severe oligohydramnios was noted. ⋯ Oligohydramnios induced by the use of angiotensin-converting enzyme inhibitors during pregnancy may be reversible if the agent is discontinued. This case underscores the need for obstetricians to review carefully the medication regimens of all pregnant women and to be familiar with generic and proprietary names of medications to avoid the use of potentially harmful agents during pregnancy.
