Delayed cervical ripening may seriously jeopardize the health of the baby and/or mother and could lead to still birth. Current methods for softening the cervix (cervical ripening), primarily involve the use of drugs such as prostaglandins and oxytocin which may have undesirable side effects.
Ultrasound energy is widely used in medical applications (diagnostic imaging, therapeutic heating and noninvasive surgery), and has an excellent safety record. Moreover, ultrasound imaging is routinely used in obstetrics to visualize the cervix of pregnant women.
Professor Bruce Towe of Arizona State University and collaborators at Dignity Health have developed a novel method for accelerating the softening of the cervix prior to labor by application of ultrasound energy. Using a compact portable device and either an intravaginal probe or an external trans-abdominal wand, pulsed ultrasound energy can be directed to the cervix to promote softening.
This method, using unique ultrasound pulse characteristics, enables a noninvasive means for safe and effective cervical ripening and has the potential to replace the use of drugs such as prostaglandins and oxytocin.
