Worked example
Fictional case: Mrs. N.J., 26 years, G1P0, emergency LSCS at 40 weeks for arrest of descent after 20 hours of labour, with atonic PPH after placental delivery not controlled by oxytocin, carboprost and bimanual compression.
Case details
Date: 11/09/2026. Emergency. Labour OT.
LSCS skin incision 03:05. Baby delivered 03:10. PPH noted 03:18. Decision for B-Lynch 03:40. B-Lynch tied 03:52. Closure completed 04:30.
Surgeon: Dr A. (3rd-year resident, OBGY). Assistant: Dr B. (1st-year resident). Consultant: Dr C., called at 03:20, present and scrubbed from 03:35.
Anaesthetist: Dr D. Scrub nurse: Sr E.
Indication and pre-op
Atonic uterus after complete delivery of placenta. Uterine incision intact, no extension, cavity empty.
Measures tried: oxytocin 5 IU slow IV at 03:11, then 20 IU in 1000 ml RL at 150 ml/h; uterine massage and bimanual compression; carboprost 0.25 mg IM at 03:22 and 03:37; tranexamic acid 1 g IV over 10 min at 03:25.
EBL 1600 ml at decision. Pulse 118/min, BP 96/60 mmHg.
Decision for B-Lynch suture by Dr C. at 03:40. Husband informed and consent taken in Hindi for B-Lynch and for hysterectomy if needed, 03:42.
4 units PRBC cross-matched, 2 units FFP requested. Second 16 G IV line placed. Hb, platelets, coagulation profile and fibrinogen sent at 03:25.
WHO checklist done before the LSCS. Inj cefazolin 2 g IV at 02:58 before skin incision; second dose 2 g IV at 03:45 as blood loss exceeded 1500 ml.
Anaesthesia and position
Spinal anaesthesia continued, patient awake and comfortable. Supine with left lateral tilt.
Findings
Uterus globally atonic, bleeding from the cavity. Bleeding reduced when the uterus was squeezed between both hands.
No broad ligament haematoma. Tubes and ovaries normal.
Procedure
Uterus exteriorised. Hysterotomy kept open. Bladder already below the lower segment.
Chromic catgut No. 2 on a large round-bodied needle.
First bite 3 cm below the right end of the incision, entering the cavity and coming out 3 cm above the upper edge of the incision.
Suture taken over the fundus about 4 cm from the right border, down the back of the uterus, and passed horizontally through the posterior lower segment at the level of the incision.
Suture taken back over the fundus on the left side, and the left anterior bites placed as a mirror of the right.
Assistant compressed the uterus with both hands. Both ends pulled up evenly and tied firmly at 03:52.
Hysterotomy closed in two layers with continuous polyglactin 910 (Vicryl) No. 1.
Uterus firm and contracted. No further bleeding from above. Vaginal bleeding minimal on check at 04:05.
No additional vessel ligation needed. Peritoneal toilet done. Broad ligaments not bulging.
Closure
No drain. Parietal peritoneum not closed. Rectus sheath continuous Vicryl No. 1. Subcutaneous fat 1.5 cm, not sutured. Skin subcuticular Monocryl 3-0.
Urine clear, 60 ml since start.
Specimens and implants
Placenta sent for HPE (PPH). No implants.
End of procedure
Total estimated blood loss 1900 ml (suction 1100 ml + weighed mops). Transfused 2 units PRBC in OT.
Mop, needle and instrument count correct, confirmed by scrub nurse.
Complication: atonic PPH, controlled with B-Lynch suture.
Shifted to HDU at 04:40. Pulse 102/min, BP 108/68 mmHg. Baby with mother, APGAR 7 and 9.
Post-op orders
HDU care. Pulse, BP, uterine tone and vaginal bleeding every 15 min for 2 hours, then every 30 min. Urine output hourly.
Oxytocin infusion 20 IU in 1000 ml RL at 150 ml/h to continue.
Hb, platelets, coagulation profile and fibrinogen at 06:00.
2 units PRBC more to be kept ready.
Catheter to stay for 24 hours.
Calf compression stockings now. LMWH once bleeding has stopped and clotting is normal, dose as per chart.
Call the consultant at once if bleeding restarts, the uterus relaxes, pulse goes above 110/min or systolic BP falls below 90 mmHg.

Must document for this operation
- Every measure tried before the B-Lynch suture, with dose and time. PPH audits check that uterotonics were used in sequence and without delay.
- Suture material and size used for the B-Lynch. If the uterus becomes ischaemic or synechiae form later, the material and tension are reviewed.
- Whether the uterine cavity was entered (opened lower segment or through the incision). The next surgeon needs to know what was done to the lower segment when planning the next delivery.
- The response: uterine tone and bleeding from above and below after tying. It shows why further surgery was or was not done.
- Total blood loss and blood products given. Needed for transfusion audit and for maternal near-miss review.
- Time of decision and name of the senior involved. PPH reviews check the time from the start of bleeding to each step, because surgery works best before coagulopathy sets in.
Common mistakes in these notes
- Writing 'B-Lynch applied' without suture material or bites described.
- Not listing the uterotonics given before the suture.
- Not checking and recording vaginal bleeding after tying.
- Leaving the time of decision out of the note.
- Writing 'EBL 1 litre' when mops and drapes were not weighed.
Indian practice and paperwork
- NABH standard COP.14(e) (5th edition) requires the operative note to be written before the patient is transferred out of recovery. (NABH Hospital Accreditation Standards 5th ed. (April 2020), COP.14 OE e)
- In NQAS-assessed public hospitals, the OT checkpoint 'Operative Notes are Recorded' looks for the people present, pre- and post-op diagnosis, procedure, length of procedure, estimated blood loss, fluids given, specimen removed and complications.
