Blast/Cracker Injury Hand

Introduction

Accidents involving blasts, gunshots, and cracker explosions can lead to severe hand injuries, often resulting in mutilation. These injuries require specialized medical attention and precise management.

Types of Injuries Causing Hand Mutilation

Hand mutilation can be caused by various types of injuries, including:

Blast Injuries: These injuries occur due to explosive devices, leading to complex polytrauma cases where the treatment of other injuries takes precedence over the hand injury. In cases of active bleeding, hemostasis is a top priority, alongside managing other injuries.

Cracker Burn Injuries: Cracker-related injuries to the hand can be of two primary types:

• Flame Burns: These injuries are typically managed with routine dressings, antibiotics, and pain relief medications.
• Blast Injuries: Occur when a cracker explodes while held in the hand, resulting in surgical emergencies that require immediate attention.

Transportation and Treatment for Blast Injuries

Managing a mutilated hand due to blast injuries, considering factors like limb ischemia and amputation, is a complex process that demands specialized skills and expertise. If there’s limb ischemia or partial amputation, the possibility of reimplantation is considered. The amputated part should be carefully transported in a plastic bag with ice at an ideal temperature of 4 degrees Celsius. Once the patient’s overall condition stabilizes and other critical injuries are addressed, the hand injury is evaluated.

Single-Stage or Multi-Stage Treatment

Patients and their families receive detailed counseling regarding the complex nature of managing blast injuries. It’s essential to clarify that these injuries typically require multiple stages of surgery and extensive effort from both the surgeon and the patient’s support system.

Initial Management at Kayakriti

At Kayakriti, the initial management of blast injuries to the hand involves:

• Upper Limb Splinting: To stabilize the injured limb.
• Wound Cleaning: Proper cleaning and irrigation of the wound.
• Vascularity Assessment: Evaluation of blood flow to the hands and fingers.
• Missing Structures Noted: Any missing or damaged hand structures are documented.
• Sensory Evaluation: Assessing sensation in the hand.
• Range of Motion Assessment: Evaluating the range of motion in the affected hand.
• Tetanus Toxoid Administration: To prevent infection.
• Pain Relief and Antibiotics: Administering pain relief medications and antibiotics.
• X-ray for Bone Injury: Assessing bone injuries.

Surgery for Blast Injuries

After initial management, the patient is planned for surgery for initial debridement to be done under suitable anesthesia.

Reimplantation is not possible or feasible in most of the cases of hand blast injuries even if the part is brought well preserved as there is injury to the vital structures at multiple levels within the part or the part is damaged beyond recognition or is in shreds. In a few isolated cases, where the part is well preserved relatively, reimplantation can be attempted with guarded consent.

• Debridement of all necrotic and dead tissues + wound irrigation of wound culture
• Antibiotics coverage with skeletal stabilization with K wires
• Management of hand fractures is done as per protocol.
• The vital structures are assessed and tagged.
• If vascularity is compromised, it can be established using microvascular technique.

In a few cases, a second relook surgery is required to debride any remaining dead tissue.

Skin and Soft Tissue Reconstruction

Once the infection load and edema decrease, the patient is planned for second-stage surgery.

• Tendon, nerves, and muscles are repaired.
• Appropriate soft tissue coverage is important for coverage of bone, joint, tendon, and neurovascular structures. The closure is done as per the protocol of the reconstruction of soft tissue defects of the hand .

Recovery After Surgery

The recovery process includes:

• Immobilization for 4 Weeks: Keeping the hand immobilized for a specific period.
• Flap Monitoring: Regular monitoring of flaps.
• Limb Elevation: Elevating the limb to minimize swelling.
• Frequent Dressing Reviews: Periodic reviews of wound dressings.
• Physiotherapy: Initiated after complete wound healing.

Results of Surgery

The outcomes of surgery for blast injuries vary depending on the extent, type, and level of injury. The road to rehabilitation can be long and challenging, and results may differ from initial expectations. The primary goal is to reintegrate patients into society with a functional hand, although this may not always be achievable.
