Polytrauma.ppt
- 2. POLYTRAUMA World wide No.1 killer amongst the younger age group (18-44 yrs). Third most common cause of death in all age group. Great economic & social loss to country. Less than 2% of budgets for health services spend on trauma patients. TRAUMA- Neglected Disease of Modern Society
- 3. POLYTRAUMA Defined as “a clinical state following injury to the body leading to profound physiometabolic changes involving multisystem’’. OR Patient with anyone of the following combination of injuries TWO MAJOR SYSTEM INJURY + ONE MAJOR LIMB INJURY. ONE MAJOR SYSTEM INJURY + TWO MAJOR LIMB INJURY. ONE MAJOR SYSTEM INJURY + ONE OPEN GRADE III SKELETAL INJURY. UNSTABLE PELVIS FRACTURE WITH ASSOCIATED VISCERAL INJURY.
- 4. Polytrauma is not synonym of multiple fractures. Multiple fractures are purely orthopaedic problem as there is involvement of skeletal system alone. While in Polytrauma there is involvement of more than one system,Like associated head/spinal injury, chest injury, abdominal or pelvic injury. Polytrauma is a multi-system injury and needs management by a team of surgeons and physicians. Orthopaedic surgeon is one of the team member of trauma unit. POLYTRAUMA / MULTIPLE FRACTURES
- 8. LIFE SALAVAGE 50% deaths due to trauma occur before the patient reaches hospital. 30% occur within 4 hrs of reaching the hospital. 20% occur within next 3 weeks in the hospital. If preventive measures are taken 70% deaths can be prevented meaning 30% deaths are nonsalvagable deaths.
- 9. AIMS IN MANAGEMENT “TO RESTORE THE PATIENT BACK TO HIS PREINJURY STATUS” HAVING FOLLOWING PRIORTIES: LIFE SALVAGE LIMB SALVAGE SALVAGE OF TOTAL FUNCTION IF POSSIBLE
- 10. PHILOSOPHY FOR MANAGEMENT ADVANCED TRAUMA LIFE SUPPORT -- based on ‘TREAT LETHAL INJURY FIRST, THEN REASSESS AND TREAT AGAIN’ The steps in management are: •Primary survey •Resuscitation •Secondary survey •Definitive care
- 11. Every team must have a final decision maker,the captain.The team must be: a) able to evaluate the patient swiftly. b) Willing to discuss the effect of the management of one problem on other. c) Able to arrive at decisions quickly. d) Efficient in regard to performing lifesaving procedures . TEAM APPROACH Anesthetist. General surgeon NeuroSurgeon Orthopedic surgeon A TEAM consists of:
- 12. Basic Emergency Medical Technician Skills 1. Maintenance of airway (endotracheal intubation?). 2. Cardiopulmonary resuscitation. 3. Intravenous access and Ringer’s lactate therapy. 4. Reduction and splintage of fractures. 5. Perform primary survey of patient and report findings to destination center. PREHOSPITAL PHASE
- 13. 2 types usually exist 1. The number of patients and severity of injuries do not exceed the ability of facility to render care. IN THIS SITUATION , PATIENTS WITH LIFE- THREATING PROBLEMS AND THOSE SUSTAINING MULTIPLE SYSTEM INJURIES ARE TREATED FIRST 2. The number of patients and the severity of their injuries exceed the Capacity of the facility and the staff. IN THIS SITUATION ,THOSE PATIENTS WITH GREATEST CHANCE OF SURVIVAL , WITH LEAST EXPENDITURE OF TIME , EQUIPMENTS , SUPPLIES AND PERSONNEL , ARE MANAGED FIRST TRIAGE Triage is the sorting of patients based on the need for treatment and the available resources to provide that treatment Ideally must be followed right from the site of the Accident
- 14. “The Golden Hour” The Golden Hour is a theory stating that the best chance of survival occurs when a seriously injured patient has emergency management within ONE hour of the injury. Platinum 10 minutes: Only 10 minutes of the Golden Hour may be used for on-scene activities
- 15. Primary Survey Airway with cervical spine control. Breathing and ventilation Circulation –control external bleeding. Dysfunction of the central nervous system Exposure (undress)/Environment(temp.) Control
- 16. PRIMARY SURVERY During the primary survey life threatening conditions are identified and management is instituted SIMULTANEOUSLY. •Airway obstruction •Tension pneumothorax •Hemothorax •Open thoracic injury and Flail chest •Cardiac temponade •Massive internal or External hemorrhage Priorities for the care of Adult , Pediatrics & Pregnancy women are all the same.
- 17. Assess Airway If pt conscious airway is maintained Open if necessary using jaw-thrust maneuver Consider oro- or naso-pharyngeal airway Note unusual sounds and correct cause Snoring – oro-/naso-pharyngeal airway Gurgling – suction Stridor – consider intubation
- 18. SIGNS OF AIRWAY OBSTRUCTION LOOK AGITATION POOR AIR MOVT. RIB RETRACTION DEFORMITY FOREIGN MATERIAL. LISTEN SPEECH?”HOW ARE YOU’’ HOARSENESS. NOISY BREATHING GURGLE. STRIDOR. FEEL FRACTURE CREPITUS. TRACHEAL DEVIATION. HEMATOMA. FACE.
- 19. DEFINITIVE AIRWAY Cuffed tube in trachea secured thoroughly with oxygen enriched gas supplementation. Indications for definitive airway- A=Airway-Obstructed airway. -Inadequate Gag reflex B=Breathing-Inadequate breathing. -oxygen saturation less then 90%. C=Circulation-systolic BP < 70 mm Hg despite resuscitation. D=Disability-Coma. -GCS less then 8/15. E=Environment-Hypothermia Core temp<33degree C.
- 20. BREAHTING LOOK Cyanosis Chest asymmetry Tachypnea. Distended neck veins. Paralysis. LISTEN I can’t breathe? Stridor Wheezing Decreased breath Sounds. FEEL Chest tenderness. Deviated trachea. Surgical emphysema. •Airway patency does not assure adequate ventilation. •Rate, Rhythm, Depth (tidal volume) •Use of accessory muscles/retractions
- 21. WHEN TO VENTILATE? Apnoea Hypoventilation. Flail chest. High Spinal cord injury. Diaphragmatic injury. Head injury GCS < 8 Hypercapnia. Hypothermia.
- 22. *Protection of the spine & spinal cord is the important management principle. *Neurological exam alone does not exclude a cervical spine injury. *Always assume a cervical spine injury in any pt with multi-system trauma, especially with an altered level of consciousness or blunt injury above the clavicle. Airway Maintenance with Cervical Spine Protection
- 23. INTUBATION IN PATIENTS OF CERVICAL INJURY
- 24. 1. cricothyroidotomy •last resort for airway control. •Y connector with O2 at 15 l/min. •Intermittent jet insufflation- sedate & paralyze, only for 30-45min. EMERGENCY RESUSC. MEASURES TO MAINTAIN ADEQUATE AIRWAY AND BREATHING
- 25. Intercostal drain 4th or 5th intercostal space, mid-axillary line local anaesthetic down to pleura ‘above the rib below’ blunt dissection. finger exploration pass large drain on forceps superior & posterior. underwater drain pursestring suture EMERGENCY RESUSC. MEASURES TO MAINTAIN ADEQUATE AIRWAY AND BREATHING
- 26. ASSESS CIRCULATION - PULSES Compare radial and carotid pulses Rhythm Regular Irregular Quality Weak Thready Bounding “Rapid,low amplitude with narrow pulse pressure indicates SHOCK.” • Rate –Normal –Fast –Slow
- 27. ASSESS CIRCULATION SKIN -Color -Temperature -Moisture BRAIN - Level of consciousness. KIDNEYS - Urine output.
- 28. CAUSES OF MAJOR BLEEDING THE BIG FIVE: EXTERNAL visual inspection Local Pressure THORACIC Primary survey and CXR . intercostals tube insertion PELVIC pelvis X-ray. Usually self limiting/ pelvic ring closure LONG BONES clinical examination. Spontaneously traction splintage ABDOMEN clinical findings/exclusion of other/USG/CT/DPL Lapratomy
- 29. Positive if Bile or intestinal contents More than 20ml frank blood aspirated prior to running in the lavage fluid After infusion of the fluid, more than 100,000 red cells/mm3 (blunt trauma) or 10-50,000/mm2 (penetrating trauma) Elevated amylase WBC > 500 / mm3 DIAGNOSTIC PERITONEAL LAVAGE (CLOSED TECHNIQUE)
- 30. 50% of trauma death are due to head injuries Simple Mnemonic to describe level of consciousness A : Alert V : Responds to Vocal stimuli P : Responds to Painful stimuli U : Unresponsive to all stimuli Not forget to use also Glasgow Coma Scale. DISABILITY ( NEUROLOGICAL EVALUATION)
- 31. Glasgow Coma Score If GCS < 10 CT head is indicated Limitations of GCS:- Does not include pupillary assessment Does not identify abnormal lateralization of motor response Minimum score is 3 Eye Opening Spontaneous 4 To voice 3 To pain 2 None 1 Verbal Response Oriented 5 Confused 4 Inappropriate words 3 Incomprehensible sounds 2 None 1 Motor Response Obeys command 6 Localizes pain 5 Withdrawn (pain) 4 Flexion (pain) 3 Extension (pain) 2 None 1
- 32. Signs of Severe Head Injury Unequal pupils Unequal motor examination An open head injury with exposed brain tissue Neurological deterioration Depressed skull fracture These are signs of severe head injury irrespective of CGS score
- 33. • Patient should be undressed to facilitate thorough examination. • Warm environment (room temp) should be maintained • Intravenous fluid should be warm. • Early control of hemorrhage. E. EXPOSURE / ENVIRONMENTAL CONTROL
- 34. A.Airway Definite airway if there is any doubt about the pt’s ability to maintain airway integrity. A definite airway is a cuffed tube in the trachea. B. Breathing /Ventilation/Oxygenation Every multiple injured pt should received supplement oxygen. A clear distinction must be made between an adequate airway and adequate breathing. RESUSCITATION
- 35. C. Circulation •Control bleeding by direct pressure or operative intervention •Minimum of two large caliber IV(16G) should be established • Lactated Ringer is preferred & better if warm. RESUSCITATION
- 36. Children less than 6 y/o for IV access is impossible due to circulatory collapse or for whom percutaneous peripheral venous cannulation had failed on two attempt Venescetion •Greater saphenous vein 2cm ant and superior to medial malleolus •Antecubital medial basilic vein 2cm lateral to medial epicondyle Intraosseous Puncture/Infusion
- 37. Initial Fluid Therapy Lactated Ringer is preferred For adult 1-2 liters bolus For child 20ml/kg bolus
- 38. 3 FOR 1 Rule a rough guideline for the total amount of crystalloid volume acutely is to replace each ML of blood loss with 3 ML of crystalloid fluid, thus allowing for restitution of plasma volume lost into the interstitial & intracellular space
- 39. RESPONSE TO EARLY RESUSCITATION MONITER: •PULSE. •BP. •SKIN - PERFUSION. •CONSCIOUSNESS •URINE OUTPUT. •-ABGs RAPID RESPONSE BE CAREFULL ,MAY STILL BECOME UNSTABLE AGAIN. & REQUIRE SURGERY . TRANSIENT RESPONSE STOP THE BLEEDING. MINIMAL RESPONSE REMEMBER THE “BIG 5”’ -GO TO O.T. ADVERSE RESPONSE •COAGULOPATHY. •HYPOTHERMIA •UNDER RESUSCITATION
- 40. Focused History and Physical AMPLE History A – allergies M – medications P – past medical history L – last oral intake E – events leading up to the incident
- 41. ADJUNCT TO PRIMARY SURVEY & RESUSCITATION A. Electro-cardiographic Monitoring B. Urinary & Gastric Catheter C. X-Ray & Diagnostic Studies C-spine lateral , CXR, Pelvic film (TRAUMA SERIES) Essential x-ray should NOT be avoid in pregnant pt.
- 42. SECONDARY SURVEY • Does not begin until the primary survey (ABCDEs) is completed, resuscitative effort are well established & the pt is demonstrating normalization of vital sign. • Head to Toe evaluation & reassessment of all vital signs. • A complete neurological exam is performed including a GCS score. • Special procedure is order.
- 43. 7. ADJUNCT TO THE SECONDARY SURVEY include additional x-ray and all other special procedure. 8. RE-EVALUATION Adult urine output 1ml/kg/hr Pediatric urine output 1ml/kg/hr 9. DEFINITE CARE
- 44. End point of resuscitation Stable hemodynamics Stable oxygen saturation Lactate level below 2 mmol / L No cogaulation disturbance Normal temp Urinary output > 1ml /kg/hr No requirement of inotropic support
- 45. Polytrauma in pregnant female Tratement priorities are same as for non pregnant pt Unless spinal injury is present pt should be examined in left lateral position Pt can loss upto 35%of blood before tachycardia and hypotension appears Fetus may be in shock while mother appears normal 1st resuscitate the female than monitor the fetus
- 46. Management of life threatening orthopedic injuries
- 47. Spinal injuries Any pt suspected of spinal injury must be immobilised unless spine has been cleared Cervical collar Spine board Log roll technique Log roll technique
- 48. Neurological shock (Low BP & HR) Spinal shock - Flaccid areflexia Flexed upper limbs (loss of extensor innervation below C5) Responds to pain above the clavicle only Priapism – may be incomplete. Diaphragmatic breathing Signs in an Unconcious patients
- 49. Spine clearance Purpose: to identify accurately and early following blunt injury to the spine the presence or absence of a diagnosis of spinal column injury Ensure that There is no spinal injury to produce avoidable disabiity or symtomps There is no important Fracture We avoid overprotection with its attendant risk In all pt consistent with spinal injury maintain spinal preacutions untill thorough clinical and radiographic evaluation of spine is completed
- 50. Pelvic injuries Pelvic injury is one of few bony injury that can lead to pt death Pelvic injuries are assesed during secondary survey Pelvis x ray is mandatory in polytrauma pt Can lead to life threatening hemorrhage Open pelvic # 50% mortality Uretheral injury transurtheral catheter or suprapubic catheter
- 51. (
- 53. Definitions of pt conditions Stable no life threatening injuries, haemodynamically stable Borderline intially respond to resuscitation but can deteriorate Unstable remain haemodynamically unstable despite initial resuscitation Extremis close to death uncontrollable blood loss
- 54. Early total care (ETC) That is defenitive fracture tretement within 24 hr ,unreamed nail prefered Used in stable pts Avoid in severe thoracic injuries haemorrhagic shock head injury Advantage pain relief , less infection, eary mobilisation, dec throemboembolism
- 55. Damage control Described by us navy as the capacity of ship to absorb damge and maintain integrity Polytrauma pts means that surgical tratements intends to control but not to defenitively repair the trauma induced injuries early after trauma Used in unstable and extremis pts
- 56. DAMAGE CONTROL •Stage 2:Physiological restoration in ICU. •Stage 3:Return to operation theatre for definitive surgery. •Stage 1:Minimum surgery is done • achieve haemostasis. •Limit the contamination •Temporary stabilisation of unstable fractures
- 57. Damage Control Surgery (“STAGED LAPROTOMY”) •Arrest bleeding , and the resulting coagulopathy. • Limit contamination and the sequelae . •Close the abdomen to limit heat and fluid loss, and to protect viscera. Damage control orthopaedics 1st stage temporary stabilisation of # 2nd stage resuscitation and optimisation 3rd stage definitive fracture fixation •External fixator is most commonly used for temporary stabilisation •Change to definitive # fixation is done in 2nd week
- 58. Priorities in fracture care Tibia Femur Pelvis Spine Upper extremity
- 59. CONCLUSION Favorable outcome for a critically injured patient demands an integrated team effort. Initial treatment is dictated by patient’s immediate physiologic requirement for survival. The definitive treatment requires rapid assessment and life preserving therapy. Damage control surgery should have a defined place in surgeons armamentarium.
