Objective: To investigate the effect of volume of water intake on the length of time before the bladder is sufficiently full prior to undergoing transabdominal ultrasound.
Methods: Ninety-three patients scheduled for transabdominal ultrasound were enrolled between November 2007 and April 2008 and randomly allocated to 3 study groups by volume of water intake: 300, 400, and 500 mL. The total waiting time was recorded when the bladder was sufficiently full to undergo transabdominal ultrasound.
Objective: To evaluate the shortening of the time of nonstress test (NST) by using transabdominal fetal stimulation with halogen light.
Study Design: Experimental research.
Material And Method: The authors enrolled 176 pregnant women between 32 and 42 weeks of gestation indicated for NST at the Division of Maternal Fetal Medicine, Siriraj Hospital, Mahidol University.
Objective: To investigate the feasibility of transperineal ultrasonography for uterine cervical assessment by determining the correlation of uterine cervical length measurement from transabdominal, transperineal and transvaginal ultrasonography and comparing discomfort arising from each technique.
Material And Method: Fifty pregnant women of 37 weeks' gestation or later who gave consent participated in this research. They had no exclusion criteria, which were listed as the following: preterm premature rupture of membranes, previous cervical surgery, undiagnosed vaginal bleeding, and true labor pain.
