Worked example
Fictional case: Mrs. N.K., 26 years, primigravida at 39+5 weeks, on epidural, second stage for 3 hours (1 hour active pushing) with late decelerations over the last 15 minutes, head 0/5 palpable, direct occipito-anterior at +2 station.
Case details
Date: 22/08/2026. Low-cavity vacuum delivery (Kiwi). Labour room 2.
Decision 09:02. Cup applied 09:08. Baby born 09:13. Placenta delivered 09:18. Repair completed 09:40.
Operator: Dr A. (2nd-year resident, OBGY). Supervisor: Dr C. (senior resident), present in room.
Paediatrician Dr F. present at birth. Staff nurse: Sr E.
Indication and pre-op
Indication: prolonged second stage with suspected fetal compromise. Late decelerations with each contraction for 15 min, baseline 150 bpm, variability normal.
P/A: head 0/5 palpable. Contractions 4 in 10 min. Estimated fetal weight about 3 kg.
P/V: cervix fully dilated, membranes absent, liquor clear. Vertex at +2 below spines, direct OA, caput +, moulding +. Descends with pushing. Classified as low, no rotation needed.
Bladder emptied by plain catheter, 150 ml clear urine. Verbal consent after explaining reason, risks and possible caesarean, husband present.
Anaesthesia and position
Epidural top-up by anaesthetist, perineal sensation checked and absent. Lithotomy. Parts cleaned with povidone-iodine and draped. Continuous CTG during procedure.
Procedure
Kiwi vacuum checked, holds pressure. Position and station confirmed again before application.
Cup placed with centre on the flexion point, 3 cm in front of posterior fontanelle on the sagittal suture. Finger swept round the cup: no vaginal wall or cervix trapped.
Pressure raised quickly to 0.8 kg/cm2 at the start of a contraction.
Traction with contractions and maternal pushing, along the pelvic curve. Pull 1: good descent. Pull 2: head on perineum. Right mediolateral episiotomy given at crowning. Pull 3: head delivered. No pop-off. Total time from application to birth 5 min.
Shoulders delivered with normal traction, no shoulder dystocia.
Live male born 09:13, weight 3.05 kg, cried at birth, APGAR 8 and 9 at 1 and 5 min. Chignon at vertex, no scalp laceration. Baby handed to paediatrician.
Cord clamped at 1 min. Paired cord blood gases taken: arterial pH 7.21, venous pH 7.28.
Inj oxytocin 10 IU IM at 09:13. Placenta delivered by controlled cord traction at 09:18, complete with membranes.
Findings and repair
Vulva, vagina and cervix inspected: no cervical or periurethral tear. Episiotomy 4 cm, apex seen. Rectal examination: anal sphincter intact, no buttonhole tear.
Episiotomy repaired: vaginal mucosa continuous from above the apex to the hymen, muscle layer continuous, skin subcuticular, all with polyglactin 910 rapid (Vicryl Rapide) 2-0.
Rectal examination after repair: no suture through the rectum. No vaginal pack.
End of procedure
Estimated blood loss 350 ml.
Swab and needle count correct, confirmed by staff nurse.
No maternal complications. Specimens: cord blood gases only.
Uterus well contracted. Pulse 90/min, BP 118/74 mmHg.
Post-op orders
Pulse, BP, uterine tone and bleeding every 15 min for 1 hour.
Record time and volume of first void. Catheterise if not voided or bladder palpable.
Single IV dose of amoxicillin-clavulanate as per unit protocol, given at 09:45.
Oral paracetamol as needed, dose as per unit protocol.
VTE risk low: early mobilisation.
Baby: paediatric check of scalp and head circumference, observe for pallor or boggy scalp swelling.
Dr A. to explain the reason for vacuum and the findings to patient before discharge.

Must document for this operation
- Abdominal fifths, station, position, caput and moulding before application. These findings justify the choice of instrument and are the first thing reviewed if the baby is injured or delivery fails.
- The indication with its evidence (CTG pattern, length of second stage). An instrumental delivery without a clear recorded indication cannot be defended in an audit or a complaint.
- Instrument type, number of pulls, pop-offs and total application time. The number of pulls and the duration are linked to scalp and intracranial injury in the baby.
- Time of decision, application and birth, and time of any decision for a second instrument or caesarean. Sequential instruments and caesarean after a failed attempt carry higher risk and are reviewed closely.
- Rectal examination result and degree of any tear. OASIS (obstetric anal sphincter injury) is more common after instrumental delivery, especially forceps, and a missed tear is treated as negligence.
- Baby condition, marks on scalp or face, and cord gases. They show the baby's state at birth, and the paediatric team uses them to decide how closely to observe.
- Operator and supervisor with grades. Training audits and complaint reviews look at who performed and who supervised.
Common mistakes in these notes
- Writing 'ventouse done' with no station, position or number of pulls.
- Writing 'fully dilated, head low' without abdominal fifths.
- Not recording pop-offs, or the reason for the pop-off.
- Leaving out the per rectal examination after delivery and after repair.
- Not recording the time the instrument was applied.
