Objective To describe labor and delivery outcomes in pregnant patients presenting to the hospital setting with an acute severe migraine headache attack earlier in the same gestation. Methods We retrospectively reviewed pregnancy and delivery records from a database of consecutive inpatient neurology consultations for acute headache in pregnant women over a 5 year period. Results We identified 86 pregnant women with acute migraine. The mean age was 29.3 (±6.4) years. Nearly half had migraine with aura (35/86 [40.7%]), 12.8% (12/86) had chronic migraine, and 31.4% (27/86) presented in status migrainosus. Complication rates included 54.7%([41/75], 95% CI 29.87, 52.13) for at least one adverse outcome, 28.0% ([21/75], 95% CI 11.78, 30.22) for preterm delivery, 21.3% ([16/75], 95% CI 7.7, 24.3) for preeclampsia, 30.6% ([23/75] 95% CI 13.48, 32.52) for cesarean delivery, and 18.7% ([14/75] 95% CI 6.15, 21.85) for low birthweight. Conclusions Pregnant women seeking treatment for acute migraine headache experienced a higher rate of preterm delivery, preeclampsia, and low birthweight but a lower rate of cesarean delivery than the local and general populations. More than half (54.7% [41/75] 95% CI 29.87, 52.13) of the study patients experienced some type of adverse birth outcome, suggesting that pregnancies in migraine patients presenting to an acute care setting may benefit from more intense surveillance.

Objective: It was our goal to determine the false-negative rate of the biophysical profile, characterize an 18-year variation in the false-negative rate, examine the relationship between the last normal biophysical profile score and death, and compare the false-negative rate of 2 disparate populations.Study Design: Biophysical profile scores of 86,955 patients at 2 medical centers were collected and recorded prospectively. All perinatal deaths occurring within 1 week of a normal score were similarly recorded. The annual false-negative rate, the cumulative false-negative rate, and the ratio of false-negative results in cases of subsequent fetal death to the perinatal mortality rate were calculated.Results: There were 65 fetal deaths among 86,955 fetuses. Over an 18-year study period at one institution, the false-negative rate varied but not significantly. The cumulative false-negative rate was 0.708 per 1000 at one medical center studied and 2.289 per 1000 at the other center. The average interval between last normal score and fetal death was 3.62 days and did not vary significantly between the medical centers.Conclusions: False-negative results in cases of subsequent fetal death reflect events that are subsequent to the last normal test result. Fetomaternal hemorrhage was the single most identifiable fetal cause of false-negative results in cases of subsequent fetal death. The ratio of the false-negative rate in cases of subsequent fetal death to the perinatal mortality rate should be used as a more objective approach to reporting this value, because the false-negative rate likely reflects the underlying perinatal mortality.
