MEDICOLEGAL CASES• A medico-legal case is a case of injury/
illness where the attending doctor, after history and examination thinks that some investigation by law enforcement agencies is essential to establish and fix responsibility for the case in accordance with the law of the land.
• Simply put, it is a medical case with legal implications or a legal case requiring medical expertise.
![Page 3: MEDICOLEGAL EMERGENCIES](https://reader036.fdocuments.in/reader036/viewer/2022062306/5884f90c1a28abf76f8b790f/html5/thumbnails/3.jpg)
EMERGENCIES• Any acute medical, surgical or obstetric
condition which deteriorates rapidly often leading to death .
• Timely and immediate intervention by trained personnel saves lives.
• Often involves Intensivist or emergency medicine consultants early in management
• Multidisciplinary approach
![Page 4: MEDICOLEGAL EMERGENCIES](https://reader036.fdocuments.in/reader036/viewer/2022062306/5884f90c1a28abf76f8b790f/html5/thumbnails/4.jpg)
THE EMERGENCIES
• Polytrauma• Poisoning• Drug overdosages• Burns• Assaults• Gun shot injuries• Drowning • Hanging• Snake /animal bite
TYPICAL ER or EMERGENCY ROOM
![Page 5: MEDICOLEGAL EMERGENCIES](https://reader036.fdocuments.in/reader036/viewer/2022062306/5884f90c1a28abf76f8b790f/html5/thumbnails/5.jpg)
Cont’d…• Cases of suspected or evident sexual assault.• Cases of suspected or evident criminal abortion.• Cases of unconsciousness where cause is not natural/ not clear• Cases of suspected self-infliction of injuries or attempted suicide• Death /arrest in the operation theatre• Brought dead to the casualty/Accident and Emergency dept / deaths occurring within 24 hours of hospitalization without establishment of diagnosis
![Page 6: MEDICOLEGAL EMERGENCIES](https://reader036.fdocuments.in/reader036/viewer/2022062306/5884f90c1a28abf76f8b790f/html5/thumbnails/6.jpg)
PROCEDURE• In the casualty - first priority is to save the life
of the patient. • He should do everything possible to resuscitate
the patient and ensure that he is out of danger.
• All legal formalities stand suspended till this is achieved.
![Page 7: MEDICOLEGAL EMERGENCIES](https://reader036.fdocuments.in/reader036/viewer/2022062306/5884f90c1a28abf76f8b790f/html5/thumbnails/7.jpg)
PRECAUTIONS
• Consent• Confidentiality • Collection and preservation of
samples• Preparation of medico-legal reports
in duplicate
![Page 8: MEDICOLEGAL EMERGENCIES](https://reader036.fdocuments.in/reader036/viewer/2022062306/5884f90c1a28abf76f8b790f/html5/thumbnails/8.jpg)
PolytraumaAirway – and total spine controlBreathing – and ventilatory support.Circulation – with haemorrhage control.Disability – brief neurological evaluation.Exposure – completely undress the patient
![Page 9: MEDICOLEGAL EMERGENCIES](https://reader036.fdocuments.in/reader036/viewer/2022062306/5884f90c1a28abf76f8b790f/html5/thumbnails/9.jpg)
AIRWAY Mandatory intubation in • GCS < 9• Severe facial injury or bleeding.• Severe facial or neck burns
Anticipate airway problems in all patients with trauma to:
• Head & Neck• Upper Thorax
![Page 10: MEDICOLEGAL EMERGENCIES](https://reader036.fdocuments.in/reader036/viewer/2022062306/5884f90c1a28abf76f8b790f/html5/thumbnails/10.jpg)
AIRWAY - Cont’d• Restlessness, decreased LOC = Hypoxia
until proven otherwise• Oxygenate, Look for cause• Oxygen is useless if patient isn’t ventilatingDanger Signs• Respirations <10• Respirations >24• Decreased tidal volume• Labored breathing
![Page 11: MEDICOLEGAL EMERGENCIES](https://reader036.fdocuments.in/reader036/viewer/2022062306/5884f90c1a28abf76f8b790f/html5/thumbnails/11.jpg)
BREATHING AND VENTILATION• Rapid assessment of respiratory rate, Spo2,
trachea , chest expansion and auscultation. • Tension pneumothorax & haemothorax - immediate
needle thoracocentesis Always exclude the following 1) Tension pneumothorax 2) Massive haemothorax 3) Open pneumothorax 4) Flail chest 5) Pericardial tamponade
![Page 12: MEDICOLEGAL EMERGENCIES](https://reader036.fdocuments.in/reader036/viewer/2022062306/5884f90c1a28abf76f8b790f/html5/thumbnails/12.jpg)
CIRCULATION & HAEMORRHAGE CONTROL
• Restlessness and anxiety especially with pallor, tachycardia, or slow capillary refill =
• Falling BP = Late sign of shock
• Don’t treat a falling BP - Prevent It!!
SHOCK
![Page 13: MEDICOLEGAL EMERGENCIES](https://reader036.fdocuments.in/reader036/viewer/2022062306/5884f90c1a28abf76f8b790f/html5/thumbnails/13.jpg)
Cont’d
• If shock present without external bleeding, think:– Thoracic or abdominal bleed– Pelvic fracture– Multiple long bone fractures– Tension pneumothorax– Cardiac tamponade
![Page 14: MEDICOLEGAL EMERGENCIES](https://reader036.fdocuments.in/reader036/viewer/2022062306/5884f90c1a28abf76f8b790f/html5/thumbnails/14.jpg)
Cont’d• Isolated head trauma does NOT cause
decreased BP in adults• Look for injuries of:
– Chest– Abdomen– Pelvis– Major long bones
![Page 15: MEDICOLEGAL EMERGENCIES](https://reader036.fdocuments.in/reader036/viewer/2022062306/5884f90c1a28abf76f8b790f/html5/thumbnails/15.jpg)
CONT’‘ D• Orthopedic injury usually NOT life-
threatening• Exceptions:
– Pelvic fracture– Femur fractures
• Assess, treat proximal to distal
• Insert 2 large IV cannula.
![Page 16: MEDICOLEGAL EMERGENCIES](https://reader036.fdocuments.in/reader036/viewer/2022062306/5884f90c1a28abf76f8b790f/html5/thumbnails/16.jpg)
CONT ‘ D
• If you don’t know the diagnosis. . .
Open, clear, maintain airwayMaximize oxygenation, ventilation
Maximize perfusion
![Page 17: MEDICOLEGAL EMERGENCIES](https://reader036.fdocuments.in/reader036/viewer/2022062306/5884f90c1a28abf76f8b790f/html5/thumbnails/17.jpg)
TRAUMA CARE CONCLUSIONS• Definitive Treatment = Surgeon’s Knife
• Trying to field-stabilize unstable trauma = Ultimate Stabilization
• Minimum time on scene ; Maximum treatment in route
• Patient MUST go to facility able to continue care appropriately
• Closest facility, facility preferred by family is NOT necessarily most appropriate
DEATH
![Page 18: MEDICOLEGAL EMERGENCIES](https://reader036.fdocuments.in/reader036/viewer/2022062306/5884f90c1a28abf76f8b790f/html5/thumbnails/18.jpg)

![Page 21: MEDICOLEGAL EMERGENCIES](https://reader036.fdocuments.in/reader036/viewer/2022062306/5884f90c1a28abf76f8b790f/html5/thumbnails/21.jpg)
21
Early Deaths (1-3 hours )
• Epidural Heamatoma• Subdural Heamatoma• Hemo/Pneumothorax• Intra-abdominal Bleeding• Pelvic Fractures• Femur Fractures• Multiple Long Bone Fractures
Why do these patients die?
![Page 22: MEDICOLEGAL EMERGENCIES](https://reader036.fdocuments.in/reader036/viewer/2022062306/5884f90c1a28abf76f8b790f/html5/thumbnails/22.jpg)
22
Late (2-4 weeks)
• Sepsis
• Multiple Organ System Failure
How can these deaths be avoided?
![Page 23: MEDICOLEGAL EMERGENCIES](https://reader036.fdocuments.in/reader036/viewer/2022062306/5884f90c1a28abf76f8b790f/html5/thumbnails/23.jpg)

Trauma Care Conclusions• Definitive Trauma Care = Surgeon’s Knife
• Short time to surgery = Improved survival
• EMS improves survival by:– Recognizing critical trauma– Supporting oxygenation, ventilation, perfusion– Transporting rapidly to definitive care
“The golden hour” concept -the platinum few minutes
![Page 24: MEDICOLEGAL EMERGENCIES](https://reader036.fdocuments.in/reader036/viewer/2022062306/5884f90c1a28abf76f8b790f/html5/thumbnails/24.jpg)
24
RECOGNIZING THE GOLDEN HOUR AND PLATINUM MINUTES
!• Where should the patient go?
The most appropriate
facility Not necessarily the closest
one!

POISONING AND DRUG OVERDOSES
• 12% of all ICU admissions in India • 30% of patients requiring ventilatory support
• 75% of all admissions due to poisonings
• MORE THAN 50% OF ICU ADMISSIONS IN CAUVERY HOSPITAL REQUIRING VENTILATION
![Page 31: MEDICOLEGAL EMERGENCIES](https://reader036.fdocuments.in/reader036/viewer/2022062306/5884f90c1a28abf76f8b790f/html5/thumbnails/31.jpg)
MANAGEMENTGeneral Measures• Decontamination of the skin is very important and
done thoroughly. • Forced emesis if the patient is fully awake or
through a gastric lavage.
• 0.5-1 g/kg activated charcoal every 4 h. Sodium sulfate or sorbitol can be used as a cathartic.
• Serotonin adipinate
![Page 32: MEDICOLEGAL EMERGENCIES](https://reader036.fdocuments.in/reader036/viewer/2022062306/5884f90c1a28abf76f8b790f/html5/thumbnails/32.jpg)
Cont’d• The airway - adequate oxygenation should be
ensured.
• Atropine can precipitate ventricular arrhythmia in hypoxic patients.
• Early use of atropine - reduces respiratory secretions,
improve muscle weakness, and thereby improve oxygenation.
• Careful observation - as these patients are prone to respiratory failure during the acute phase and intermediate syndrome.
![Page 33: MEDICOLEGAL EMERGENCIES](https://reader036.fdocuments.in/reader036/viewer/2022062306/5884f90c1a28abf76f8b790f/html5/thumbnails/33.jpg)
Things to look for…..The important parameters to be monitored on a
regular basis are
• Symptoms of ocular muscle involvement (e.g.;
diplopia),• Neck muscle weakness• Tidal volume / vital capacity/RR• Single breath count• Arterial blood gas estimation or pulse oximetry.
![Page 34: MEDICOLEGAL EMERGENCIES](https://reader036.fdocuments.in/reader036/viewer/2022062306/5884f90c1a28abf76f8b790f/html5/thumbnails/34.jpg)
Specific therapy Anticholinergic Agent• Mainstay of treatment • Atropine can be started initially as a 2.4mg IV
bolus and then repeated at doses of 2-5 mg IV bolus every 5-15 min until atropinization is achieved.
• Most commonly used regimen is 0.2mg/kg/hour titrated to desired effect
![Page 35: MEDICOLEGAL EMERGENCIES](https://reader036.fdocuments.in/reader036/viewer/2022062306/5884f90c1a28abf76f8b790f/html5/thumbnails/35.jpg)
Target end-points for Atropine therapy
• Heart rate >80/ min, Systolic blood pressure >80
• Dilated pupils
• Dry axillae ,Drying of all secretions
• Chest clear of secretions and crepts.
![Page 36: MEDICOLEGAL EMERGENCIES](https://reader036.fdocuments.in/reader036/viewer/2022062306/5884f90c1a28abf76f8b790f/html5/thumbnails/36.jpg)
Oximes• PRALIDOXIME (2-PAM).
– OPCs bind and phosphorylate one of the active sites of AChE and inhibit the functionality of this enzyme.
– Oximes bind to the OP causing the compound to break its bond with AChE – REACTIVATION.
– AGEING IS A CONCERN.
• The main therapeutic effect of pralidoxime is due to recovery of N-M transmission at nicotinic synapses.
• However, oximes also enhance cholinesterase activity at muscarinic sites decreasing the requirement for atropine.

Supportive measures• Never forget co-existing diseases and medical
conditions
• Primarily supportive
• VAP-protocol
• DVT prophylaxis and thromboembolism prevention
• “ FAST HUG ME ”
![Page 38: MEDICOLEGAL EMERGENCIES](https://reader036.fdocuments.in/reader036/viewer/2022062306/5884f90c1a28abf76f8b790f/html5/thumbnails/38.jpg)

BURNS• Classification-Degree and percentage of
burnsMajor burns• 3rd degree or full thickness involving more than 10% BSA
• 2nd degree or partial thickness involving more than 25% BSA
• Burns involving face, hands and feet • Inhalational /chemical /electric burns and burns in pts with
co-existing medical diseases.
![Page 40: MEDICOLEGAL EMERGENCIES](https://reader036.fdocuments.in/reader036/viewer/2022062306/5884f90c1a28abf76f8b790f/html5/thumbnails/40.jpg)
ABC IN BURNS• Secure airway early, as intubation is likely to be
difficult once edema has set in.
• In a child nasal intubation is preferred over oral
• Smoke inhalation and ALI
• CO poisoning.
• Eschorotomies
![Page 41: MEDICOLEGAL EMERGENCIES](https://reader036.fdocuments.in/reader036/viewer/2022062306/5884f90c1a28abf76f8b790f/html5/thumbnails/41.jpg)
circulation• Parkland formula 4ml/kg/% of BSA burnt 50% of it in first 8hrs
25% each in remaining 8 hrs each
• Mount vernon regimen
• Brook’s formula
• Modified brook’s regimen
![Page 42: MEDICOLEGAL EMERGENCIES](https://reader036.fdocuments.in/reader036/viewer/2022062306/5884f90c1a28abf76f8b790f/html5/thumbnails/42.jpg)
DROWNING• ABCs – maintain airway at earliest
• Always keep in mind drug and alcohol intoxication
• Beware of prognosticating only with pupil size and reaction
• Hypothermia ----cerebroprotective!!!
• Consider mannitol and diuretics
![Page 43: MEDICOLEGAL EMERGENCIES](https://reader036.fdocuments.in/reader036/viewer/2022062306/5884f90c1a28abf76f8b790f/html5/thumbnails/43.jpg)
Attempted Hanging• ABCs • Secure airway, cervical spine control• Liberal use of steroids• Cerebral edema and hypoxia– major
determinant• Mannitol• Supportive measures.
