PMC-L2.1

Wounds, closure and suturing

PMC-M2 · Treatment on board · PMC-M2-A Wound closure, infection control and the medical emergencies most likely aboard.

Table A-VI/4-2 expects you to be able to **close a wound**. The skill is less the stitch than the judgement: clean it properly, know which wounds to leave open, and spot infection early.

Wounds

Governing: Table A-VI/4-2 'wounds, wound healing and infection', 'techniques of sewing and clamping', 'minor surgical treatment', 'dressing and bandaging'.

Assessment

Look at Why
Mechanism Crush, bite, high-pressure injection and dirty objects change everything
Site Face, hands, joints and over tendons need care and often specialist repair
Depth and length Deep wounds may involve tendons, nerves or vessels
Function beyond the wound Movement and sensation of fingers or toes; loss suggests tendon or nerve injury
Contamination Soil, marine growth, rust, bilge water
Age of the wound Older wounds are more likely to be infected

Cleaning

Wear gloves. Control bleeding (MFA lesson 2.1 for tourniquets). Irrigate generously with clean water or sterile saline; a syringe gives useful pressure. Remove visible debris. Clean the surrounding skin. This step prevents more infections than any antibiotic.

Closure options

Method Use
Adhesive strips Small, straight, low-tension cuts; no anaesthetic needed
Tissue glue (if carried) Small, clean cuts; not over joints or in moist areas
Sutures Gaping wounds under tension; requires anaesthetic and a sterile field
Staples (if carried) Scalp and straight wounds
Clamping Artery forceps on a visible bleeding vessel while help is sought

The stitch itself (usually simple interrupted, knots to one side, edges just meeting, not strangled) is learned on the practical part of the course. The SCMG and TMAS will direct the material, anaesthetic and technique.

When not to close

  • Bites (human or animal) and heavily contaminated wounds.
  • Puncture wounds, including fish spines and sea urchins.
  • Wounds more than a few hours old, unless TMAS advises.
  • Wounds with suspected tendon, nerve or joint involvement.
  • High-pressure injection injuries from hydraulic or fuel lines, which look small and are surgical emergencies.

Leave these open, dressed, and seek advice. Delayed closure ashore is better than an abscess at sea.

Aftercare

Record the site, length, depth, method and number of sutures. Check the wound daily. Plan removal dates with TMAS. Signs of infection: spreading redness, heat, swelling, increasing pain, pus, red streaks up the limb, fever. These need a TMAS call and may need antibiotics.

Minor surgical procedures

A-VI/4-2 includes minor surgical treatment: draining a superficial abscess, removing a splinter or fish hook, treating a subungual haematoma. Do these only within your training and, where in doubt, on telemedical advice.

CAUTION — Hands Yacht crew work with their hands: lines, winches, galley knives, stainless fittings. Any hand wound with loss of movement or feeling goes to a hand specialist; do not close it and hope.

TIP — Photographs Photograph the wound before and after closure, with a scale. MGN 623 notes photographs can support a TMAS consultation.

recall · core

Which wound should generally NOT be closed on board without advice? (a) A clean scalp cut (b) A clean, fresh 2 cm laceration on the forearm (c) A dog or human bite (d) A superficial cut suitable for adhesive strips

recall · core

What is the most important step before closing any wound? (a) Suturing as quickly as possible (b) Covering it with a tight bandage (c) Thorough cleaning with irrigation and removal of debris (d) Applying antiseptic cream inside it

recall · core

Which sign suggests wound infection? (a) Spreading redness, increasing pain, swelling, pus or fever (b) Itching during healing (c) A dry scab (d) Mild pink edges on day one

scenario · core

A deckhand cuts his palm deeply on a stainless fitting. It is gaping, bleeding controlled by pressure, and he cannot fully bend one finger. Port is 3 days away. What do you do? (a) Clean and dress it, splint the hand, and call TMAS: loss of finger movement suggests tendon damage that needs specialist repair (b) Suture it closed and carry on (c) Glue it and let him return to work (d) Leave it undressed to breathe
