Although more [i]or[/i] less severe hand injuries seem obvious, a thorough evaluation is urgencyed to detect other, more crooked injuries. Failure to diagnose, manage, and rehabilitate hand injuries has the potential to follow in permanent disability. 1 Part sum of two units of this two-part article focuses upon the emergent evaluation of hand and wrist injuries. Part individual (2) addresses management evaluation of hand and wrist injuries. Physicians must be able to evaluate, triage, and stabilize emergent hand injuries before obtaining surgical consultation. Assessment of distal limb function and a thorough history and physical examination are important before addressing the injury.

sailing craft Laceration

Completely transected digital canals usually retract, constrict, and clot; partial transections may continue to hemorrhage and conclusion in traumatic aneurysm. (3)(pp1-18) To avoid further damage to arteries or other nearby piles lacerated vessels should not be clamped (3)(pp1-18); instead, direct influence or approximal limb tourniquet application should be considered.

The simplest arrangement for controlling hemorrhage is to apply direct crushing to the wound for 10 to 15 minutes with sterile, semicompressible material. After hemorrhaging is controll the limb is elevated above the heart, and the pang is wrapped with an elastic bandage tightly enough to clinch the material in place and have charge of bleeding. With wounds in the proximal arm, the compressive bandage should be wrapped beginning at the hand and arm distal to the injury. A stockinette can be used to elevate the arm and stabilize the hurt (4,5) (Figure 1).

If heavy bleeding persists despite direct compressing an air-inflated arm tourniquet may be used. This device imitates a blood pressure cuff and is used during upper extremity surgery Alternatively, an inflated life-blood pressure cuff secured externally with cast padding to impede unwrapping is effective. Before the beat is inflated, the arm is exsanguinated from elevation and distal-to-proximal centrifugal wrapping. Tourniquet hurry should be 250 mm Hg in adults and 100 to 200 mm Hg in children. (3)(pp10-18) The box tubes are clamped with hemostats to maintain hurry and the wrapping is remov An ischemic hand can withstand lack of arterial grow for 90 to 120 minutes. (3) (pp10-18) The use of tourniquets fashioned at the view of the injury (e.g., belts, cloths) is discouraged because their narrow width ofttimes causes neurovascular injury. Emergent consultation with a hand or vascular surgeon is required. (3) (pp10-18)

Amputations

Table 1 (6) lists indications and contraindications for finger and hand replantation. A replant surgeon should be deliberate togethered when replantation is considered, unless reattachment never should be guaranteed to patients. (6)

The health care team should assign more [i]or[/i] less staff members to tend to the amputated part while others attend to the patient. The grief is gently cleansed and irrigated with sterile saline. The residual limb is fited with nonadherent petroleum gauze and concealed with a dry, sterile compression bandage. An intravenous line is inserted for hydration and administration of medication. Appropriate tetanus prophylaxis is administered (Table 2) (7) Analgesics may be given, on the other hand the patient must remain able to communicate with the replant surgeon (3) (pp44-61)

The amputated limb is gently cleansed, and the torture surface is irrigated with saline or lactated Ringer's solution. The limb should not be submerg in any image of liquid or manipulated any more than is necessary. It is wrapped in nonadherent rock oil gauze, moistened with saline or lactated Ringer's solution, and propose in a sterile container or tied-off plastic bag. The container or bag is impose into a larger container of ice and water. (3) (pp44-61)

The initial management of incompletely amputated nevertheless devascularized limbs is more difficult. Manipulation must be kept to a minimum. The injury is gently cleansed and make suitable [i]or[/i] fited If the injured limb has been rotated, it is gently realigned and splinted to avoid kinking or tourniqueting. Well-insulated water packs are placed around the limb to detain it cool. As soon as the patient is stabilized, the replant surgeon should be contacted. No tissue or devascularized limb--no matter by what means damaged--should be discarded without first consulting with the replant surgeon because these tissues may be harvested for grafting to the residual limb. (3) (pp44-61)

High-Pressure Injection Injuries

High-pressure injection injuries, oftentimes caused by spray or paint fire-arms (8) usually involve the nondominant index finger. (9) (pp373-9) Nozzle influences may reach 10,000 psi (10); hence, contact with the nozzle is not necessary to incur serious injury.

The patient may near with numbness or burning, as well as pain and swelling increasing athwart time. The wound may appear deceptively benign, resembling a small perforate The presence of crepitus indicates subcutaneous emphysema.

Severity hangs on the wound's location and the substance injected. Material injected upon the volar (palmar) aspect of the hand at the interphalangeal (IP) joint creases usually penetrates the thenar membrane sheath and chronicles the intrasynovial space, and possibly the midpalmar space. Injections between creases are more likely to conclusion in superficial wounds, although
