C. GENERAL EXAMINATION (CONT.)
7 . Conclusion- Just a short history with the facts.- Never give name of accused- Avoid trying to narrate actual events as per person giving it
because it might not be the same as in police statement and these differences can be used by defence to dispute evidence in court
![Page 10: MEDICOLEGAL ASPECTS OF TRAUMA MANAGEMENT Dr T. Kombora](https://reader031.vdocument.in/reader031/viewer/2022022404/56649cf05503460f949bf7c5/html5/thumbnails/10.jpg)

E. GYNAECOLOGICAL EXAMINATION
1 . Breast development use Tanner Stage 1 – 52 . Pubic Hair use Tanner Stage 1 - 5 - Tanner Staging best way to determine discrepancies
between apparent and chronological ages3. Examine external genitalia noting any injuries old or new4. Hymen- Use clock notation to describe position of injuries 5. Vagina - Use clock notation to describe injuries. Record any
vaginal delivery in past 6 months and if any lesions result of it6. Cervix and Perineum
![Page 13: MEDICOLEGAL ASPECTS OF TRAUMA MANAGEMENT Dr T. Kombora](https://reader031.vdocument.in/reader031/viewer/2022022404/56649cf05503460f949bf7c5/html5/thumbnails/13.jpg)
F. SAMPLES TAKEN FOR INVESTIGATION
1. Forensic Specimen taken2. Urine Pregnancy Test3. Seal number of Evidence Collection Kit4. Note name, rank, Force Number of person given Kit for preservation
on chain of evidence5. Conclusion
- Do not use term rape - if negative eg “ absence of injuries does not exclude forcible
penetration of vulva or vagina by penis or other object” - if positive eg “ injuries compatible with forcible penetration
past labia majora with bruising of hymen” - State if injuries confirm to time and date of alleged incident
![Page 14: MEDICOLEGAL ASPECTS OF TRAUMA MANAGEMENT Dr T. Kombora](https://reader031.vdocument.in/reader031/viewer/2022022404/56649cf05503460f949bf7c5/html5/thumbnails/14.jpg)

![Page 17: MEDICOLEGAL ASPECTS OF TRAUMA MANAGEMENT Dr T. Kombora](https://reader031.vdocument.in/reader031/viewer/2022022404/56649cf05503460f949bf7c5/html5/thumbnails/17.jpg)
J . ANNEXURE
. This is a declaration that said Medical Officer has done the examination on the person mentioned in the J88
![Page 18: MEDICOLEGAL ASPECTS OF TRAUMA MANAGEMENT Dr T. Kombora](https://reader031.vdocument.in/reader031/viewer/2022022404/56649cf05503460f949bf7c5/html5/thumbnails/18.jpg)
PITFALLS IN COMPLETING J88
. Failure to do adequate exam and describe full extent of injuries and poor documentation
. Not signing on every written page
. Use of abbreviations like NAD and medicolegal terms ( layman terms to be used)
. sketches that difficult to note esp with use of pen of same colour with sketches
. Making a subjective diagnosis which is scientifically impossible
![Page 19: MEDICOLEGAL ASPECTS OF TRAUMA MANAGEMENT Dr T. Kombora](https://reader031.vdocument.in/reader031/viewer/2022022404/56649cf05503460f949bf7c5/html5/thumbnails/19.jpg)
WOUND DESCRIPTION
• Open– Laceration– Incision wound– Abrasion– Puncture– Penetration wound– Gunshot wound – Entrance and exit wounds
• Closed– Contusion– Hematoma
![Page 20: MEDICOLEGAL ASPECTS OF TRAUMA MANAGEMENT Dr T. Kombora](https://reader031.vdocument.in/reader031/viewer/2022022404/56649cf05503460f949bf7c5/html5/thumbnails/20.jpg)
LACERATION• Laceration – Irregular tear like wound caused by blunt trauma or
heavy edged weapons like axes or hatchet
![Page 21: MEDICOLEGAL ASPECTS OF TRAUMA MANAGEMENT Dr T. Kombora](https://reader031.vdocument.in/reader031/viewer/2022022404/56649cf05503460f949bf7c5/html5/thumbnails/21.jpg)
ABRASION• Abrasion - Superficial with loss of epidermis. Caused by skin coming
into moving contact with a rough surface. If more traumatic with loss of all sin layers then its an avulsion
![Page 22: MEDICOLEGAL ASPECTS OF TRAUMA MANAGEMENT Dr T. Kombora](https://reader031.vdocument.in/reader031/viewer/2022022404/56649cf05503460f949bf7c5/html5/thumbnails/22.jpg)
CONTUSION
• Contusion - Blunt force causes rupture of capillaries and venules with extravasation of blood into extracellular space
![Page 23: MEDICOLEGAL ASPECTS OF TRAUMA MANAGEMENT Dr T. Kombora](https://reader031.vdocument.in/reader031/viewer/2022022404/56649cf05503460f949bf7c5/html5/thumbnails/23.jpg)
Haematoma
• Haematoma – Collection of blood under the skin
![Page 24: MEDICOLEGAL ASPECTS OF TRAUMA MANAGEMENT Dr T. Kombora](https://reader031.vdocument.in/reader031/viewer/2022022404/56649cf05503460f949bf7c5/html5/thumbnails/24.jpg)
PUNCTURE• Puncture - Sharp thin object like a needle, nail or screwdriver
puncturing skin
![Page 25: MEDICOLEGAL ASPECTS OF TRAUMA MANAGEMENT Dr T. Kombora](https://reader031.vdocument.in/reader031/viewer/2022022404/56649cf05503460f949bf7c5/html5/thumbnails/25.jpg)
INCISION WOUND• Incision Wound - regular margins cased by sharp edged object like
knife, razor or glass
![Page 26: MEDICOLEGAL ASPECTS OF TRAUMA MANAGEMENT Dr T. Kombora](https://reader031.vdocument.in/reader031/viewer/2022022404/56649cf05503460f949bf7c5/html5/thumbnails/26.jpg)
PENETRATION WOUND• Penetration Wound – Sharp object entering body eg knife
![Page 27: MEDICOLEGAL ASPECTS OF TRAUMA MANAGEMENT Dr T. Kombora](https://reader031.vdocument.in/reader031/viewer/2022022404/56649cf05503460f949bf7c5/html5/thumbnails/27.jpg)
GUNSHOT WOUNDS• BALLISTICS. Calibre – Approximate diameter of a bullet in inches, in a rifled
barrel this is the distance between consecutive lands or grooves
. A moving projectile has kinetic energy proportional to its weight and velocity KE= MV2/g
.Wounding effect due to transfer of KE from projectile to tissues
. The greater the angle of yaw with subsequent tumble and wobble the greater the damage the greater the loss of KE
. Calibre and mass of projectile influence the “drag effect”. Structure of projectile important
. The denser the tissue the greater the loss of KE
![Page 28: MEDICOLEGAL ASPECTS OF TRAUMA MANAGEMENT Dr T. Kombora](https://reader031.vdocument.in/reader031/viewer/2022022404/56649cf05503460f949bf7c5/html5/thumbnails/28.jpg)
GUNSHOT WOUND. Several mechanisms of injury by bullets ; - Direct laceration with low velocity rounds forming single
permanent cavity - High velocity tend to form a large temporary cavity due to the
great KE, lasts 5-10 msec. If pressure of temporary cavity exceeds elastic limit of tissue then it will burst eg liver
- Shockwaves receeding from projectile can rupture hollow viscus like bowel
- Secondary projectiles eg shattered bone fragments - Discharge gases from muzzle of gun

COLLECTING EVIDENCE FROM GSW
• Victim’s clothes may yield information on range of fire or distinguish entrance from exit wounds
• Package items of clothing separately to cross contamination and place in paper bags (to avoid the static electricity in plastic bags which would lift evidence from clothes)
• In suspected shooters wrap their hands in paper bags for later test of GSR
• When removing bullets cover haemostats/forceps with gauze to preserve the microscopic “fingerprint” of each bullet
• Bullets must be collected in breathable containers eg paper boxes or envelopes not airtight containers
• When in doubt over GSWs describe what u see not guessing
![Page 36: MEDICOLEGAL ASPECTS OF TRAUMA MANAGEMENT Dr T. Kombora](https://reader031.vdocument.in/reader031/viewer/2022022404/56649cf05503460f949bf7c5/html5/thumbnails/36.jpg)
THE INTOXICATED PATIENT
. Issue of collecting bloods ; Section 37 of the Criminal Procedure Act of 1977 states that blood samples can be taken by medical officer of any prison or any district surgeon and also any registered MO or nurse can do so on request of police.
. It gives authority to do this against will of subject( provided he is lawfully arrested) and allows use of reasonable force without this constituting assault
. However in other 1st world countries it’s a bit different you need patient consent and its recommended that police surgeons do the collection
![Page 37: MEDICOLEGAL ASPECTS OF TRAUMA MANAGEMENT Dr T. Kombora](https://reader031.vdocument.in/reader031/viewer/2022022404/56649cf05503460f949bf7c5/html5/thumbnails/37.jpg)
CONSENT
. Duty of treating doctor to advise and explain benefits and risk of any treatment to be administered to patient
. Done in two stages : 1) Assessment of legal capacity to consent 2) The process of obtaining that consent. On assessment age, consciousness and whether of sound mind
considered
![Page 38: MEDICOLEGAL ASPECTS OF TRAUMA MANAGEMENT Dr T. Kombora](https://reader031.vdocument.in/reader031/viewer/2022022404/56649cf05503460f949bf7c5/html5/thumbnails/38.jpg)
UNAUTHORISED ADMINISTRATION
. Negates need for consent on basis of medical ‘necessity’
. There must be a real state of emergency
. The patient must be unaware of the fact that he is being medically treated, or must at least be incapable of properly appreciating the situation
. The treatment must not be against the will of the patient
. The treatment must be intended to be in the best interest of the patient
![Page 39: MEDICOLEGAL ASPECTS OF TRAUMA MANAGEMENT Dr T. Kombora](https://reader031.vdocument.in/reader031/viewer/2022022404/56649cf05503460f949bf7c5/html5/thumbnails/39.jpg)
JEHOVAH’S WITNESSES
.First consider whether patient is competent to give or refuse consent
.Refusal of blood transfusion by a legally competent person is binding but it must be his own decision, free of undue influence
. If incompetent adult( eg unconscious) the views of relatives are not binding. However, we should respect a formal advance directive ,made when competent, that no blood may be given
. In cases of minors the issue might need to go before the courts which usually grant permission for the transfusion
