Worked example

Fictional case: Mr. S.B., 56 years, type 2 diabetic, 3 weeks after two debridements for necrotising fasciitis of the left leg. Medial and posterior calf wound 22 x 11 cm with healthy granulation. Wound swab 5 days ago: no Streptococcus pyogenes, scanty Pseudomonas.

Case details

Date: 05/11/2026. Elective split-thickness skin grafting, left leg. OT 5.

In OT 09:30. Spinal given 09:40. Graft harvest started 09:55. Dressing completed 10:50.

Surgeon: Dr A. (2nd-year resident, General Surgery). Assistant: Dr B. (1st-year resident). Consultant: Dr C., present in OT.

Anaesthetist: Dr D. Scrub nurse: Sr E.

Indication and pre-op

Indication: granulating raw area left leg after debridement for necrotising fasciitis, too large for direct closure.

Hb 10.8 g/dl, serum albumin 3.3 g/dl. Fasting blood sugar 142 mg/dl on insulin.

Pseudomonas on swab is not a bar to grafting as granulation looks healthy.

Donor site: left anterolateral thigh, marked.

Consent: general, procedure-specific and anaesthesia consent taken in Hindi from patient, son as witness.

WHO checklist sign in and time out done. Inj cefazolin 1 g IV at 09:35, before incision.

Anaesthesia and position

Spinal anaesthesia. Supine, left knee slightly flexed with leg rotated out to expose the medial calf. No tourniquet. Left lower limb from groin to toes painted with povidone-iodine and draped.

Findings

Recipient bed 22 x 11 cm on medial and posterior calf. Red, flat granulation with good marginal epithelium. Gastrocnemius covered by granulation. No exposed tendon or bone. No slough.

Procedure

Recipient bed scraped with the back of a scalpel blade to remove the top layer of granulation until fresh bleeding. Saline-soaked mops applied with pressure for haemostasis.

Donor thigh lubricated with liquid paraffin. Assistant held the thigh from behind to make the front firm and convex. Skin stretched between two paraffin-coated wooden boards.

Graft harvested with Humby knife set for intermediate thickness, using a to-and-fro motion. Two strips, each about 20 x 7 cm.

Donor site: uniform fine punctate bleeding, no fat exposed. Saline mop applied with pressure.

Grafts kept in saline on a moist gauze with raw side up. Window cuts made in the grafts with a No. 15 blade.

Grafts spread raw side down on the recipient bed, overlapping the edges slightly. Fixed at the margins with skin staples. No air or clot left under the graft.

Excess graft about 6 x 4 cm stored in saline gauze in a labelled sterile container at 4 degrees C.

Closure

Recipient: paraffin gauze (tulle gras), saline-moistened cotton, gauze pads, roller cotton and crepe bandage from toes to knee. Below-knee posterior plaster slab to keep the ankle still.

Donor: paraffin gauze, gauze, roller cotton and crepe bandage.

End of procedure

Estimated blood loss 150 ml. No transfusion.

Mop, needle and instrument count correct, confirmed by scrub nurse.

No intra-operative complications.

Specimens: none. Implants: none.

Patient shifted to post-operative ward in stable condition. Pulse 84/min, BP 130/78 mmHg.

Post-op orders

Left leg elevated on a pillow. Bed rest till first graft inspection.

Recipient dressing to be opened on POD 5 for graft check, earlier if soakage, fever or foul smell.

Donor dressing not to be removed for 10 days. If soaked, add outer layers only.

Analgesia as per chart. Blood sugar 6-hourly, insulin as per sliding scale.

High-protein diet.

Stored graft to be used or discarded at the POD 5 inspection.

Must document for this operation

  • State of the recipient bed and the culture result before grafting. If the graft fails, the review will ask whether the bed was ready and Streptococcus pyogenes was excluded.
  • Donor site, instrument and thickness setting. The next surgeon needs this if regrafting is needed, and thickness explains how fast the donor site heals.
  • Size of graft and of the area covered, and whether meshed or fenestrated. It helps judge percentage graft take at the first dressing.
  • Method of fixation and immobilisation. Ward staff must know if staples or tie-over sutures are to be removed, and a slab changes nursing care.
  • Dressing plan with dates for recipient and donor sites. Early removal of the donor dressing causes pain and delays healing, and a missed recipient check hides infection.
  • Any stored graft, where it is kept and its label. Stored skin is used only if it is clearly identified as this patient's own.

Common mistakes in these notes

  • Writing 'SSG done' with no donor site, size or instrument.
  • No record of wound culture before grafting.
  • Leaving out the dressing plan and dates for donor and recipient sites.
  • Not noting a splint when the graft crosses a joint.
  • Not recording stored graft and its label.

Indian practice and paperwork

  • The ICMR antimicrobial guideline lists no antibiotic or a single perioperative dose of cefuroxime or cefazolin for clean (class I) operations, given within 1 hour before incision. (ICMR Treatment Guidelines for Antimicrobial Use in Common Syndromes 2019, Table 10.1 and section 10.3.8 (printed pp. 97-99))
