2. Short-handled outlet forceps often kept ready at caesarean section.
4. The anterior fontanelle is where the sagittal, frontal, and _______ sutures meet.
6. A symptomatic caesarean scar niche with >3mm ________ myometrial thickness can be remodelled hysteroscopically.
8. Intrauterine balloon tamponade device for PPH. A recent study looked at how long to retain these balloons and found there was no difference between 6-7 hours and longer (Garabedian et al 2026).
9. Bleeding within the layers of the neonatal scalp, between the skull bone and periosteum. It stops at the suture lines.
12. At caesarean, the risk of caesarean scar niche can be reduced with an unlocked double-layer suture of the uterus where the first layer does not incorporate the ___________.
13. The posterior fontanelle is where the sagittal suture meets the ________ suture.
14. A procedure preserving placental circulation at caesarean section while managing the fetal airway, when extreme airway difficulty is anticipated.
16. At vaginal breech birth, the widest part of the baby’s hips is called the ______________ diameter.
17. A technique that can be used for the impacted fetal head at caesarean section, involving birth of the arms and shoulders first, then the fetal body, and finally the head.
21. 2019 RCT showing a single dose of IV amoxicillin/clavulanic acid after instrumental birth can reduce the risk of infection from 19% to 11%.
25. Myometrial defect at a prior caesarean scar, also called an isthmocele.
26. Bleeding within the layers of the neonatal scalp, between the aponeurosis and periosteum. It can cross suture lines, and a significant volume of blood can be lost.
28. Family who kept the obstetric forceps a secret for generations.
29. Rotational forceps that have almost no pelvic curve and a sliding lock.
30. Tear involving rectal mucosa with an intact anal sphincter complex.

1. Most invasive form of abnormal placentation, breaching the uterine serosa.
3. Obstetrician whose 1950s labour curve long underpinned definitions of normal labour progress.
5. Airway scoring system used to predict the difficulty of endotracheal intubation prior to general anaesthetic.
7. Spinal anaesthesia rapidly blocks the thoracolumbar nerve roots which encompass the ___________ chain. Blockade can lead to rapid hypotension.
10. Nerve block with infiltration about 1cm inferior and medial to the ischial spine.
11. An epidural catheter passes through the ligamentum flavum into the epidural space. A spinal needle continues through two layers of meninges into the ____________ space, where there is CSF. The presence of CSF in the needle is used as a confirmatory sign of needle tip placement.
15. The suture technique often used as the third layer at classical caesarean section, colloquially referred to as a “baseball stitch”, is more accurately called a ___________ stitch.
18. The WOMAN trial showed that __________ acid reduces death in postpartum haemorrhage.
19. Modified ______ Manoeuvre. A method of controlling speed of delivery of the fetal head and perineal guarding, by applying upward pressure from the perineum with one hand, while using fingers of the other hand on the fetal occiput to maintain flexion of the fetal neck during contractions.
20. Rare rescue manoeuvre for shoulder dystocia, where the fetal head is replaced into the uterus ahead of caesarean delivery.
22. At fetoscopic laser of the placenta for twin-twin transfusion syndrome, anastomoses are photocoagulated, and then a _______ line is photocoagulated along the equator between each twins’ placental territory.
23. Cut diathermy uses a __________, low voltage waveform to vaporise tissue. Coagulation diathermy uses intermittent, high voltage waveforms to desiccate tissue.
24. Mentum ________. A face presentation with maximal hyperextension of the fetal neck; for which vaginal delivery is not recommended.
27. Compression brace suture technique used to mechanically compress an atonic uterus, first described in 1997.
