Table 4 Intrapartum surveillance of the foetus

From: Stillbirths and quality of care during labour at the low resource referral hospital of Zanzibar: a case-control study

  Case-control study BW ≥2000 g
Cases Intra-hosp. Stillbirths Controls Apgar 710
N (%)
Of women with at least one FHR reading: (n = 72) (n = 204)
 FHR in normal range on admission (110–160 beats per min.) 72 (100.0 %) 202 (99.0 %)
 Foetal distress detected prior to delivery 15 (20.8 %) 0 (0.0 %)
 <90 min. between any 2 recordings of FHRa 12 (16.7 %) 67 (32.8 %)
 Median time from last FHR till delivery or detected IUFD (min.)b,c 210 120
  1. BW birthweight, CI confidence interval, FHR foetal heart rate, min. minutes, OR odds ratio
  2. aDifference between intra-hospital stillbirths and controls: OR 0.41, 95 % CI 0.21–0.81
  3. bIt was possible to calculate average time from last FHR till delivery in 63 (86 %) cases and 176 (86 %) controls. The interquartile ranges were 75–315 min. and 63–238 min., respectively
  4. cFor each one-hour increase in duration from last FHR assessment, the odds of stillbirth increased 20 % (OR 1.20; 95 % CI 1.08–1.34)
