PRINCIPLES OF ADVANCED TRAUMA LIFE SUPPORT BY DR MS AMINU 1
History ATLS has its origins in the US in 1976, when James K Styner, an Orthopedic surgeon piloting a light aircraft, crashed into a field in Nebraska. His wife, Charlene was instantly killed while 3 of his four children, Richard, randy and Kim sustained critical injuries. 2
History His son, Chris suffered a broken arm. He carried out the initial triage of his children at the crash site. Dr Styner had to flag down a car ro transport him to the nearest hospital, upon arrival, he found it closed. Even when the hospital was opened, the emergency care was inadequate and inappropriate. 3
History The initial ATLS course was held in 1978. in 1980, the American College of Surgeons Committee on Trauma adopted ATLS and began US and international dissemination of the course. 4
ATLS Represents an organized approach for evaluation and management of trauma patients. Has 2 phase Pre-hospital phase Hospital phase 5
PREHOSPITAL PHASE This covers the initial phase pf trauma management Covered normally by first responders in the field at the site of the trauma prior to transfer to a hospital Triage is carried out and patient are sorted out according to urgency prior to transport to the health care facility. 6
OBJECTIVES By the end of this session, we will be able to Review core principle and ABCDE approach Discuss rapid primary/ secondary survey technique Master critical interventions (hemorrhage control, airway management) 7
WHY ATLS Trauma kills >5 million/year globally. In the US, it’s the #1 cause of death for ages 1-44. But here’s the key: systematic care reduces mortality by 30% . ATLS isn’t optional – it’s how we buy time in the Golden Hour. 8
CORE ATLS PHILOSOPHY Key principles: Treat greatest threat to life first. Never delay resuscitation for diagnostics ABCDE: Sequential & concurrent priorities 9
INITIAL ASSESSMENT AND MANGEMENT Preparation (Prehospital – Hospital) Triage Primary survey (ABCDE) Resuscitation Adjuncts to primary survey 10
INITIAL ASSESSMENT AND MANGEMENT Secondary survey Adjuncts to secondary survey Post-resuscitation monitoring Definitive care 11
PRIMARY SURVEY Treatment priorities A: Airway maintenance + C-spine protection B: Breathing and ventilation C : Circulation ad hemorrhage control D: Disability – Neuro E: Exposure/ Environment control 12
A - Airway Airway Patency/ obstruction Severe head injury -> Definite airway 13
Open Pnemothorax > 2/3 of tracheal diameter Rx: 3 sided dressing Chest tube insertion 25
Open Pnemothorax 26
Open Pnemothorax 27
Flail Chest > 2 ribs fractured in 2 or more places Paradoxial chest wall movement Rx: 28
Massive Haemothorax > 1500ml of blood (1/3 of blood volume) in the chest cavity Rx IV resuscitation Chest tube Thoracotomy >1500ml immediately 200ml/ hr for 2 – 4 hours 29
Haemorrhagic Shock Most common cause of shock in trauma External vs Internal haemorrhage Rx: volume replacement 35
Haemorrhagic Shock Classification Class I 15% blood loss PR < 100bpm BP normal PP normal RR 14 – 20 Urine output > 30 ml/ hr Mental status: Slightly anxious 36
Haemorrhagic Shock Classification Class II 15 – 30% blood loss PR > 100bpm BP normal PP decreased RR 20 – 30 Urine output: 20 – 30 ml/ hr Mental status: mildly anxious 37
Haemorrhagic Shock Classification Class III 30 – 40% blood loss PR > 120bpm BP decreased PP decreased RR 30 - 40 Urine output: 5 – 15ml/ hr Mental status: confused 38
Haemorrhagic Shock Classification Class IV >40% blood loss PR > 140bpm BP decreased PP decreased RR >35 Urine output: ----- Mental status: confused/lethargic 39
Fluid Replacement Class I, II: Crystalloid Class III, IV : Crystalloids, blood Initial fluid therapy 1-2 L for adults 20 ml/kg for children 40
Response to Fluid Resuscitation Rapid response <20% blood loss Cross-match, Surgical consultation Transient response 20 – 40% blood loss Ongoing blood loss Blood transfusion, surgical intervention 41
Response to Fluid Resuscitation No response Immediate operative intervention 42
Neurogenic Shock Isolated intracranial injuries do not cause shock Loss of sympathetic tone: Spinal cord injury Hypotension without tachycardia Initially treated as hypovolemia DDx of non-responder 46
D Neurological Status Loss of consciousness (AVPU / GCS) Pupil size and light reaction Lateralizing signs Spinal cord injury level 47
D A : Alert V : Verbal command P : Painful stimuli U : Unresponsive 48
D Factors that affect level of consciousness Oxygenation Ventilation Perfusion Hypoglycemia Drugs/ Alcohol 49
D Reevaluation 50
E : Exposure/ Environment Uncloth patient Logroll patient and look for hidden injuries Prevent hypothermia Warm blanket Warm IV fluid 51
E : Exposure/ Environment Rectal examination Sphincteric tone Position of the prostate (high-riding) = urethral injury Gross blood (penetrating abdominal injury) Pelvic fractures 52
Conclusion The knowledge of ATLS is an invaluable tool in the arsenal of every orthopaedic surgeon, as such efforts must be made to gain this skill as it could very well be the deciding factor between life and death of a trauma patient 59
