Scalp wounds can bleed far more than they look like they should — a cap that holds the pressure gives the responder's hands back for the injuries that kill faster.
At a glance
9 things to know about the Trauma Cap
Why scalp bleeding deserves a device, how the cap works, and when firm pressure on the head is the wrong move.
-
01
Built to replace a hand on the scalp
Rescue Essentials describes the Trauma Cap as a patented device designed and tested by emergency physicians to serve as a mechanical replacement for manual pressure on scalp lacerations — apply it and move on to other injuries.3,4
-
02
Scalp bleeding is not trivial
A scalp laceration can bleed enough to cause shock, and a wound that looks quiet in a patient in shock can bleed heavily once blood pressure is restored.6 In the Japan Trauma Data Bank, 14.0% of patients 65 or older with an isolated scalp laceration needed a red-cell transfusion within 24 hours, against 2.6% of younger patients.7
-
03
Anchor behind, fasten in front
The elastic straps share a common anchor point that sits firm behind the head; the bands pull forward and fasten with hook-and-loop to the front of the cap, and can cover the ears if needed.3
-
04
Extra straps add compression
Additional fastener straps go across the scalp for more compression, and the straps can be adjusted to set the pressure.3
-
05
An optional chin strap
The chin strap is optional and adds security.3
-
06
The cap is not the dressing
The Trauma Cap is non-sterile; a sterile gauze pad goes on the wound first and the cap holds it there.3,4
-
07
Gentle pressure only on an open skull
For a penetrating head wound or an open skull fracture, the TCCC Guidelines call for a surface dressing, hemostatic gauze on the surface with gentle pressure if it is actively bleeding, and nothing packed into the wound.1 If you feel bone move or see brain tissue, do not crank the straps down.
-
08
Another option for scalp bleeding: the iTClamp
For head and neck wounds whose edges can be easily brought together, the TCCC Guidelines list the iTClamp as a primary option.1 In 80 prehospital scalp and face cases from the maker's surveillance database, it was reported to give adequate control in 87.5%.8
-
09
Class I, latex-free, not on the evidence-based list
Tri-Tech Forensics, Rescue Essentials' parent company, lists the Trauma Cap with the FDA as an elastic bandage (product code FQM), Class I and 510(k)-exempt; the label marks it latex-free.3,5 The evidence-based list does not name it, and absence from the list does not by itself mean a product was tested and failed.2
How to apply the Trauma Cap
Rescue Essentials' instructions, with the head-injury cautions from the TCCC Guidelines.
-
1Look for worse first. Life-threatening bleeding elsewhere, the airway and breathing come before a scalp wound. A tourniquet goes on any limb bleeding that needs one — high and tight over clothing under threat or when the source cannot be seen, on bare skin 2–3 in. above the wound once it is exposed.1
-
2Pad on the wound. Place a sterile gauze pad on the bleeding scalp wound.3
-
3Open skull? Gentle only. If the skull is open or the wound is penetrating, use a surface dressing and only gentle pressure, and never pack the wound.1
-
4Cap on, anchor behind. Open the cap and apply it to the head with the elastic strap anchor point behind the head.3
-
5Pull and fasten. Pull the elastic bands forward until their common anchor point is firm behind the head, and secure the hook-and-loop fasteners to the front of the cap. Cover the ears if needed.3
-
6Add compression. Apply the extra fastener straps across the scalp for more compression, and the optional chin strap for added security.3
-
7Monitor and adjust. Watch for bleeding through the pad, the level of consciousness and the airway, and adjust the straps as needed.3
-
8If it bleeds through. A scalp wound is not packed: leave the first pad in place, add gauze on top and refasten. Do not peel off the pad to look.
Where it fits
- Bleeding scalp lacerations — holding a sterile gauze pad under steady pressure3
- Freeing a responder's hands when there are other injuries or other casualties3,4
- Keeping a head dressing in place through extrication and transport
- Most head sizes — one size fits most, with adjustable straps3
- Firm pressure over an open skull fracture or penetrating head wound — gentle pressure only1
- Packing — never pack a head wound
- Eye injuries — a penetrating eye injury gets a rigid eye shield, not a pressure patch1
- Taking the place of a sterile dressing — the cap is non-sterile4
The evidence
No study has tested the Trauma Cap itself. These are the guideline and the scalp-bleeding studies behind the advice above.
| Study | Evidence type | What was studied | What it found |
|---|---|---|---|
| TCCC Guidelines, 1 May 2026 | Expert review · guideline | Head and neck hemorrhage; penetrating traumatic brain injury and open skull fracture | iTClamp may be a primary option where wound edges re-approximate; for penetrating TBI, surface dressing, hemostatic gauze on the surface with gentle pressure, never pack the cavity |
| Okumura et al., Acute Med Surg 2026 | Human · trauma registry | 304 patients with isolated scalp lacerations, Japan Trauma Data Bank 2019–2023 | Red-cell transfusion within 24 h in 14.0% of patients 65 or older vs 2.6% younger; age ≥65 (OR 4.5) and arrival systolic BP <90 (OR 6.1) independently linked to transfusion |
| Turnage & Maull, South Med J 2000 | Human · case report | Scalp laceration in a blunt-trauma patient in shock | Scalp lacerations can cause hypovolemic shock; bleeding became profuse as blood pressure was restored |
| McKee et al., J Inj Violence Res 2019 | Human · case series | 80 prehospital scalp and face cases from the iTClamp maker's post-market surveillance database | Adequate hemorrhage control reported in 87.5%; direct pressure and packing abandoned for the clamp in 27.5% |
The registry and case data are about scalp bleeding itself and about the iTClamp, not the Trauma Cap. The iTClamp series comes from its manufacturer's post-market reporting database, not a controlled study.
How it compares
The ways to control a bleeding scalp, side by side.
| Trauma Cap | iTClamp | Manual pressure on gauze | |
|---|---|---|---|
| How it controls bleeding | Elastic cap and straps hold pressure on a gauze pad | Clamps the wound edges together | A responder's hand presses gauze on the wound |
| Gauze pad | Required — a sterile pad goes under the cap | Not required; may be used with a hemostatic dressing | Required |
| Hands free once applied | Yes | Yes — needs no added direct pressure | No |
| Where it fits | Scalp lacerations | Head and neck wounds whose edges can be brought together; never within 1 cm of the eye | Any compressible wound |
| evidence-based standard | No | Yes — iTClamp | Not a device |
