Sudden heavy bleeding from a residual limb: direct pressure, tourniquet, then the surgeon

Why amputation haemorrhage is an immediate threat

Amputation divides major arteries and veins that are tied off or sealed during surgery. If a ligature slips or a vessel reopens, especially in the early postoperative period, bleeding can be brisk and arterial. Because the limb is wrapped in bulky dressings, blood may first appear as rapidly spreading staining or pooling beneath the stump rather than an obvious spurt.

Major blood loss can produce shock within minutes, so this is a circulation emergency that outranks pain control, phantom sensation or positioning. Many units keep a tourniquet at the bedside of a new amputee for this reason. The nurse should know where it is and how to apply it before it is ever needed, as part of routine safety checks.

First action: firm direct pressure and a call for help

Press firmly over the bleeding area with gloved hands and gauze or the dressing, without removing soaked layers, and add more dressings on top if blood seeps through. Elevating the residual limb slightly can help, provided it does not delay pressure. Call for help immediately using the emergency call system, so a colleague can contact the surgeon and bring supplies.

Do not lift the dressing repeatedly to check whether bleeding has stopped, because that disrupts clot formation. Keep pressure continuous and stay with the client. A second nurse can take vital signs and prepare IV access while you maintain pressure. Reassure the client briefly, since sudden bleeding is frightening and movement can worsen it.

When and how the bedside tourniquet is used

If firm direct pressure does not control bleeding that appears life threatening, apply the tourniquet above the bleeding point, proximal to the wound and not over a joint, and tighten it until the bleeding stops. Note the exact time of application and tell the surgeon. Leave the tourniquet visible, and do not loosen or remove it until the surgical team is present.

A tourniquet is a temporary measure that stops blood flow to the residual tissue, so it buys time for the surgeon rather than solving the problem. Applying it when simple pressure would work exposes the client to tissue ischaemia without benefit. Local protocols and the surgeon's instructions determine exactly when the bedside tourniquet is used and who may apply it.

Assess for shock and prepare for return to theatre

Monitor pulse, blood pressure, respiratory rate, oxygen saturation, skin colour and temperature, level of consciousness and urine output. Tachycardia, cool clammy skin, restlessness and falling blood pressure indicate hypovolaemia. Lay the client flat if hypotensive, ensure IV access and start fluids as ordered, and prepare for blood tests, crossmatch and transfusion according to the prescriber's plan.

Keep the client fasting and gather information the surgeon needs: time of onset, estimated loss, vital sign trend, anticoagulant use and what has been done. Return to theatre to secure the vessel is likely. Document times precisely, including tourniquet application, and keep family informed when the client is stable enough for that conversation.

Worked example and the distractors

In a hypothetical scenario, a client one day after a below-knee amputation calls out that his bed is wet, and the dressing is rapidly soaking with bright red blood. Options are to remove the dressing to locate the source, apply firm direct pressure and call for help, check his blood pressure, or reposition the limb flat on the bed.

Direct pressure with a call for help is the first action because it immediately limits blood loss. Removing the dressing wastes time and disturbs clot; vital signs matter but do not stop bleeding and a colleague can obtain them; repositioning alone does nothing for an open vessel. If pressure fails and bleeding remains severe, the bedside tourniquet comes next.
