First aid for contusions

Contusion is a common closed injury requiring prompt measures to limit hemorrhage into the tissues. Basic first aid consists of local cooling of the injury zone, ensuring rest, and proper application of a pressure bandage.

Cooling regimenIce is applied for 2 hours with obligatory 30–40 minute breaks.
Thermal proceduresHeating pads and Sollux lamps are used exclusively from the 2nd–3rd day after the injury.
Surgeon's tacticsLarge hematomas are subject to puncture on the 5th–7th day.
AbrasionsProtected with film-forming agents, healing proceeds under a scab.

Action algorithm for the first 24 hours

The primary task in the first 24 hours after sustaining a contusion is to maximally limit the volume of internal bleeding into the soft tissues. The following tactics are used for this:

  • Application of a pressure bandage directly to the site of the contusion.
  • Use of cold. An ice pack is the optimal option, as it helps constrict blood vessels and reduce hemorrhage. Follow a strict regimen: cold is applied for 2 hours, followed by a 30–40 minute pause.
  • Actions for hemarthrosis. If hemorrhage into the joint cavity has occurred, it is critically important to ensure complete rest. The injured limb must be elevated, and a tight pressure bandage applied to the joint itself.

Important: if concomitant bone injury is suspected, transport immobilization is mandatory for the victim even at the pre-hospital stage.

Treatment on days 2–3

After the first forty-eight hours, the treatment tactics change drastically. Cold is completely discontinued, as the risk of ongoing bleeding decreases. The stage of applying thermal procedures begins.

The patient is prescribed medical heating pads or warming with a Sollux lamp. Heat exposure is necessary to locally dilate blood vessels, improve microcirculation, and significantly accelerate the resorption of the already formed hemorrhage.

Tactics for large hematomas

If the volume of extravasated blood is large, conservative heat treatment may be insufficient. In such cases, minimally invasive surgical intervention is required:

  1. On the 5th–7th day after the injury, the physician performs a hematoma puncture.
  2. The accumulated liquid blood is completely removed via a needle.
  3. Immediately after the procedure, a pressure bandage is applied to the affected area (not to be confused with an aseptic, occlusive, or plaster bandage — in this case, a pressure bandage is specifically required).

Management of concomitant superficial injuries

Contusions are often accompanied by superficial skin injuries — abrasions and minor wounds. The main goal of pre-hospital care is to stop bleeding from small vessels and prevent infection.

  • Wound edges (the skin around the defect, but not the wound itself) are treated with an iodine solution.
  • Bleeding is stopped by applying a standard bandage.
  • For isolated abrasions, it is advisable to use film-forming agents as a primary dressing. They create a reliable protective film on the surface. After antiseptic treatment, further healing of such defects proceeds safely under a scab.

Outpatient treatment and primary surgical debridement (PSD)

Patients with contusions, abrasions, and small wounds are treated in an outpatient clinic. If the wound (incised, bitten, lacerated, puncture, or contused) requires edge excision and primary closure, primary surgical debridement (PSD) is indicated.

PSD is a set of measures aimed at rapid wound healing without complications. The procedure must be radical, single-stage, and definitive. It begins with wound toilet (cleaning the surrounding skin with warm water and soap, alcohol, hydrogen peroxide, or gasoline; shaving hair) and mandatory local or general anesthesia.

How to memorize

The «Cold-Heat» rule: on day 1 — ice (constrict vessels), from days 2–3 — heating pad (resorb blood).

Class and exam questions

Can you apply heat to a contusion on the first day?

Strictly forbidden. In the first 24–48 hours, only cold (ice pack) must be used to stop the bleeding. Thermal procedures are prescribed no earlier than 2–3 days.

How to properly apply ice to a contusion site?

The ice pack should be applied for up to 2 hours, with mandatory 30–40 minute breaks to prevent tissue frostbite.

What does first aid for hemarthrosis consist of?

In case of joint hemorrhage, it is necessary to ensure complete rest for the joint, elevate the limb, and apply a pressure bandage directly to the joint area.

On which day are large hematomas punctured?

Puncture followed by blood removal and application of a pressure bandage is performed on the 5th–7th day after the injury.
