Intrapartum fetal stimulation tests: a meta-analysis.

Objective: To assess the performance of stimulation tests for the prediction of intrapartum fetal acidemia.

Data Sources: We conducted a MEDLINE (Internet Grateful Med) literature review from 1966 to 2000 using the terms "fetal scalp pH," "fetal scalp stimulation," and "fetal acoustic stimulation."

Study Selection: Articles were included if sensitivity, specificity, and predictive values for intrapartum fetal acidemia could be calculated.

Effectiveness of Selective Use of Intravenous Pyelography in Patients Presenting to the Emergency Department with Ureteral Colic.

Objective: To determine whether IV pyelography (IVP) is required routinely for all patients presenting to the ED with ureteral colic.

Methods: A randomized prospective study was conducted with 2 patient groups-a routine IVP group, in which all patients underwent IVP, and a selective IVP group, in which patients were treated, observed, and released without undergoing IVP unless they experienced continued symptoms. The study was performed in a large university-affiliated, community hospital ED.
