Diagnostic value of ultrasound in obstetrics and gynecology

The Safe Use of Diagnostic Ultrasound in Obstetrics and Gynecology

The diagnostic ultrasound was considered safe after the intensity threshold was known and the output intensity (Ispta) was regulated to be less than 10 mW/cm2 in diagnostic devices in Japan, and diagnostic ultrasound was thought safe in USA when both thermal index (TI) and mechanical index were less than 1.0 in the obstetrical setting. Simple B-mode machine was not concerned from the thermal re...

General Obstetrics and Gynecology: Obstetrics

Objective: We tested if fetal pulse oximetry in addition to electronic fetal monitoring (CTG) and scalp blood sampling improves the accuracy of fetal assessment and allows safe reduction of operative deliveries ( 50%) and scalp blood sampling ( 50%) performed because of nonreassuring fetal status. Study design: A randomized controlled trial was conducted in 146 patients with term pregnancies in...

Simulation in obstetrics and gynecology.

Simulation is a practical and safe approach to the acquisition and maintenance of task-oriented and behavioral skills across the spectrum of medical specialties, including obstetrics and gynecology. Since the 1990s, the profession of obstetrics and gynecology has come to appreciate the value of simulation and major steps are being taken toward incorporating this technique into specialty-specifi...
