“…Although the risks of hypoxic ischaemic encephalopathy (HIE) and neonatal mortality were different between groups I and III, the wide confidence intervals for the risk ratio suggests some imprecision. Our findings corroborate those of previous publications 31,36 that reported that the rate of neonatal acidosis is linked with indications for emergency delivery. Future studies should discern the factors that significantly ameliorate the risk of neonatal morbidity with emergent caesarean.…”

“…Although our result shows a slower rate of decline in pH than that estimated by Wood et al, 9 our value was similar to the rate of 0.01 per minute decline in pH reported in cases of placental abruption and cord prolapse. 13 This rate is faster than that in the case of vaginal twin delivery, in which the rate of decline in cord arterial pH of the second twin was 0.0046 per minute after the first twin's delivery. 14,15 Our observation suggests that the likelihood of developing severe acidosis (pH < 7) within an HBDI of 5 minutes is relatively low, as only 0.5% of our Art., arterial; AS5, Apgar score at 5 minutes; BE, base excess; DM, diabetes; HBDI, head-to-body interval; Ven., venous.…”

“…16 This paradoxical phenomenon was also demonstrated in Group 2, and likely resulted from a selection bias, in which the severe cases with poorer outcome were delivered urgently, whereas mild cases with good outcome tended to be delivered less urgently. 17,18 Only when we analyzed according to different fetal heart rate patterns and defined the time period from the onset of bradycardia, was the correlation revealed.…”

“…Cord arterial pH drops at 0.009 per minute, which is similar to our previously reported rate of 0.011 per minute in other irreversible causes such as abruptio placentae and shoulder dystocia. 18,34 Hence, a decision-to-delivery interval of less than 15 minutes (or bradycardia-to-delivery interval of less than 20 minutes)…”
