Gunshot wounds from ordinary firearms differ significantly from military projectiles. They are typically made of soft lead, easily deformed, have low initial velocity, and are fired at close range. Common weapons include revolvers, pistols, Flobert guns, and shotguns. Shotguns produce either highly destructive or relatively harmless wounds depending on the distance. At close range, a single charge lacerates tissues; at long range, multiple small perforations occur.
<Callout type="important" title="Critical Examination">Careful examination of the firearm used, nature of the projectile, and patient's position is crucial for medico-legal reasons. Examine ears, nose, mouth, head for exit wounds or bullet location under scalp.</Callout>
For head injuries, especially those involving suicide attempts, focus on the right temple or forehead. If a depression without penetration is found, pack with sterile gauze and bandage; later use X-rays to locate and remove bullets if necessary.

Spinal injuries require immediate attention if symptoms suggest severe cord damage. Operate to remove bone fragments and debris but avoid probing or disinfecting the spinal canal unless there are clear indications.
Thoracic wounds demand conservative treatment initially, covering with sterile compresses and avoiding unnecessary explorations. Abdominal gunshot wounds present a more urgent situation; operate immediately if signs of visceral injury are evident.
Key Takeaways
- Careful examination and documentation of the firearm used is essential for medico-legal reasons.
- Head injuries require thorough inspection for foreign bodies and proper wound management.
- Spinal wounds may need immediate surgical intervention if there are signs of severe cord damage.
- Thoracic gunshot wounds should be treated conservatively unless symptoms indicate urgency.
- Abdominal gunshot wounds often necessitate prompt surgery to address visceral injury.
Practical Tips
- Always assume the presence of foreign bodies in gunshot wounds and treat accordingly.
- Use X-rays for locating bullets that cannot be easily found or removed without causing further damage.
- For spinal injuries, avoid unnecessary probing to prevent infection and additional harm.
- In abdominal cases, prepare for laparotomy if there are signs of visceral injury.
Warnings & Risks
- Failure to document the firearm used can lead to legal complications in civil practice.
- Ignoring medico-legal aspects can result in incomplete treatment or misdiagnosis.
- Improper handling of spinal injuries can worsen prognosis and cause permanent damage.
Modern Application
While this chapter provides valuable insights into treating gunshot wounds, modern medical advancements have improved diagnostic tools (like CT scans) and surgical techniques. However, the principles of thorough examination, careful documentation, and prompt intervention remain crucial for effective emergency care.
Frequently Asked Questions
Q: What are the key differences between civil and military firearm projectiles?
Civilian firearms typically use soft lead bullets that deform easily upon impact, have lower initial velocity, and are fired at close range. Military projectiles tend to be harder and more aerodynamic.
Q: Why is careful examination of the firearm important in civil practice?
Careful examination helps establish medico-legal context, aids in understanding wound characteristics, and guides appropriate treatment based on the type of weapon used.
Q: What should be done if a bullet is not visible but suspected to be lodged within tissue?
If a bullet cannot be easily located or removed without causing further damage, it may be left in place with plans for later removal using X-rays or other imaging techniques.
Q: How should spinal injuries from gunshot wounds be managed?
Spinal injuries require careful examination to determine the extent of cord involvement. Immediate surgical intervention may be necessary if there are signs of severe damage, but probing and disinfection should be avoided unless absolutely required.
