Midline episiotomy at vacuum birth linked to more sphincter injury
A 5,277-delivery US cohort separates midline from mediolateral cuts at operative birth. Also: what Crimean-Congo haemorrhagic fever does in pregnancy, CBT for postnatal depression, and a biased opioid after caesarean.
The edition in brief
In 5,277 operative vaginal deliveries from the US MFMU APEX cohort, any episiotomy was associated with higher odds of obstetric anal sphincter injury (adjusted OR 1.45, 95% CI 1.25-1.67), but the cut mattered: midline episiotomy at vacuum delivery was associated with more injury whatever the parity, while mediolateral episiotomy was associated with less injury in women without a previous vaginal birth. This is observational and the mediolateral group was small. A patient-level pooled analysis of 55 pregnancies with Crimean-Congo haemorrhagic fever found maternal mortality of 28.8% and fetal loss of 57.4%; third-trimester ribavirin was associated with lower maternal mortality (OR 0.33, 95% CI 0.13-0.84). The disease is endemic in parts of western India, so a febrile, bleeding pregnant woman with livestock or tick exposure needs it on the list. A meta-analysis of eight trials (1,811 women) found cognitive behavioural therapy lowered EPDS scores (SMD -0.59) and nearly doubled clinical improvement (RR 1.84), with evidence certainty very low to moderate. A 94-woman Chinese trial found tegileridine PCA after elective caesarean cut nausea and vomiting from 23.9% to 6.5% with similar pain control; the drug is not available in India and the trial is small.
Crimean-Congo haemorrhagic fever in pregnancy: about three in ten mothers died
Keep CCHF on the differential for a febrile, bleeding pregnant woman with tick or livestock exposure, and isolate early.
Cognitive behavioural therapy for postnatal depression: a moderate effect on symptoms
Refer women with a raised EPDS for structured CBT, while assessing risk at the same visit.
Tegileridine after caesarean: less nausea, same pain relief, in a small trial
Target nausea as hard as pain after caesarean; tegileridine itself is not yet a practical option.
Examine the perineum and the anal sphincter after every operative birth
After every instrumental birth, do a rectal examination before you start suturing.
At operative birth, the type of episiotomy matters more than whether you cut
When an episiotomy is needed at operative birth, favour mediolateral over midline.
