10) Although both uterine tachysystole
and nonreassuring fetal-heart tracing are well recognized potential complications of misoprostol use, (19) and such events did occur in this research, none of the studies demonstrated a difference in maternal or fetal outcomes between the outpatient and inpatient settings.
Incidence of uterine tachysystole
and hyperstimulation is reported to be higher then Prostaglandin E2 vaginal tablet18.
Maternal outcome in terms of nausea vomiting, loose motions, fever, PPH, uterine tachysystole
, blood transfusion and puerperal sepsis were considered.
The elective induction bundle includes four criteria: a gestational age of at least 39 weeks, a normal fetal status at the start, pelvic exam documented prior to the start, and recognition and management of uterine tachysystole
Secondary outcome measures included length of time for preinduction cervical ripening, total time for induction, delivery route, uterine tachysystole
, side effects, subject comfort, and other fetal heart rate disturbances.
The insert had to be removed after about 6 hours because of active labor in 19 patients, ruptured membranes in 5, uterine tachysystole
in 5, and nonreassuing fetal heart rates in 2.
After 6 hours, she develops uterine tachysystole
with recurrent variable decelerations but the oxytocin infusion is continued at the same rate (FIGURE 6).
One disadvantage with Misoprostol is uterine tachysystole
and hyperstimulation with further foetal distress.
For example, early on we surveyed EVMS residents and labor and delivery nurses about how they defined uterine tachysystole
One disadvantage with Misoprostol is slightly increased incidence of uterine tachysystole
and hyperstimulation and hyperstimulation with further fetal distress.
Induction included cervical ripening with misoprostol followed by oxytocin, resulting in uterine tachysystole
and an abnormal fetal heart-rate pattern.
A concern in the use of misoprostol for induction of labour is tachysystole 3,6 It appears that the incidence of uterine tachysystole
is dose related as indicated by an incidence of 17% with the 25mg dose (8) 37% with 50mg (6) and 72% with 100mg dose.
