  1. 1. PRIMARY ASSESSMENT AND PREOPERATIVE MANAGEMENT OF MAXILLOFACIL AND HEAD INJURIES INDIAN DENTAL ACADEMY Leader in continuing dental education www.indiandentalacademy.com www.indiandentalacademy.com
  2. 2. INTRODUCTION www.indiandentalacademy.com
  3. 3. DEATHS FOLLOWING RTA’S Immmediate deaths (50 per cent) Early deaths (30 per cent) Late deaths (20 per cent) www.indiandentalacademy.com
  4. 4. TRIMODAL DISTRIBUTION OF DEATH www.indiandentalacademy.com
  5. 5. STEPS IN MANAGEMENT Primary survey- identify what is killing the patient. Resuscitation- treat what is killing the patient. Secondary survey- proceed to identify all other injuries. Definitive care- develop a definitive management plan. www.indiandentalacademy.com
  6. 6. PRIMARY SURVEY AND RESUSCITATION Primary survey of the patient follows a strict sequential protocol. Airway and Cervical spine control. Breathing and Ventilation. Circulation and Hemmorhage control. Disability = Neurological status. Exposure + Environment. www.indiandentalacademy.com
  7. 7. CERVICAL SPINE There should be high index of suspicion for cervical spine injury in the patient with maxillofacial injuries or multisystem trauma, if the patient has an altered level of consciousness or if there is history of high speed impact. www.indiandentalacademy.com
  8. 8. CERVICAL SPINE Assume injury to cervical spine if – Blunt trauma above clavicles Head injury Maxillofacial trauma Multiple trauma www.indiandentalacademy.com
  9. 9. CERVICAL SPINE CONTROL Definitive cervical spine control requires the application of semi rigid cervical collar, sandbags placed on either side of the head and tapes over the forehead and chin, immobilizing the head and neck to the trolley. www.indiandentalacademy.com
  10. 10. CERVICAL SPINE CONTROL In the restless and agitated patient, immobilizing the head and neck while allowing the rest of the body to move can damage the cervical spine and here just a semirigid collar is acceptable. www.indiandentalacademy.com
  11. 11. AIRWAY Assessment must rapidly be made as to whether the patient can maintain and protect his own airway. If the patient is able to respond verbally, the airway, at least for the time being, is patent but repeated assessment is prudent. www.indiandentalacademy.com
  12. 12. AIRWAY Teeth, dentures, vomitus, hematoma and other foreign bodies may block the airway - right main bronchus - susceptible. Earlv in the primary survey, the oral cavity should be cleared using a finger sweep followed by aspiration. www.indiandentalacademy.com
  13. 13. AIRWAY Hemorrhage may result from several causes to obstruct the airway. Bleeding from vessels in open wounds can be controlled by pressure with gauze swabs. Soft tissue swelling and edema resulting from trauma to the oral cavity may compromise the airway. www.indiandentalacademy.com
  14. 14. The fractured nose may need to be packed as a result of damage to the anterior or posterior ethmoidal vessels or the maxillary artery. www.indiandentalacademy.com
  15. 15. AIRWAY The tongue can often fall back and obstruct the airway in unconscious patients and in these a simple chin lift or jaw thrust maneuver can be used to correct the tongue position and open the airway. www.indiandentalacademy.com
  16. 16. CHIN LIFT Chin lift should be performed without hyperextending the neck. The mandible is gently lifted upward using the fingers of one hand placed under the chin. The thumb of the same hand lightly depresses the lower lip to open the mouth. www.indiandentalacademy.com
  17. 17. JAW THRUST Jaw thrust is performed by grasping the angles of the mandible with one hand on each side and displacing the mandible forward. www.indiandentalacademy.com
  18. 18. TONGUE STAY SUTURE www.indiandentalacademy.com
  19. 19. INDICATIONS FOR DEFINITIVE AIRWAY Apnea Inability to maintain patent airway by other means need to protect the lower airway from blood or vomit potential compromise of the airway, e.g. following inhalational injury, facial fractures etc. The presence of a closed head injury requiring assisted ventilation (GCS ≤ 8) An inability to maintain adequate oxygenation by face mask oxygen supplementation. www.indiandentalacademy.com
  20. 20. DEFINITIVE AIRWAY This provides oxygen assisted ventilation via a cuffed tube present in the trachea with the cuff inflated and the tube secured in place with a tape. Three types Orotracheal intubation Nasotracheal intubation Surgical (cricothyroidotomy & tracheostomy) www.indiandentalacademy.com
  21. 21. ALOGRITHM LEADING TO SURGICAL AIRWAY www.indiandentalacademy.com

  28. 28. TRACHEOSTOMY www.indiandentalacademy.com
  29. 29. TRACHEOSTOMY www.indiandentalacademy.com
  30. 30. SUPPLEMENTAL OXYGEN Supplemental oxygen delivered through a well-fitting re-breathing mask at a rate of l5 litres per minute to achieve maximum oxygenation of the tissues, should be given to every trauma patient. www.indiandentalacademy.com
  31. 31. BREATHING AND VENTILATION Once the airway has been secured, breathing and ventilation must be assessed. Direct trauma to the chest - pain with breathing and leads to rapid shallow breathing - hypoxemia. Intracranial injury - abnormal patterns of breathing and compromise the adequacy of ventilation. Cervical spinal cord injury - diaphragmatic breathing and interfere with the ability to meet increased oxygen demands. www.indiandentalacademy.com
  32. 32. BREATHING AND VENTILATION Thoracic injuries that are immediately life threatening include Flail chest Tension pneumothorax Open pneumothorax Massive hemothorax Cardiac tamponade These should be identified in the primary survey. www.indiandentalacademy.com
  33. 33. EXAMINATION All the clothes covering the front and sides of the patients chest must be removed. The respiratory rate, effort and symmetry should be recorded, because these are sensitive indicators of underlying pulmonary contusion, hemothorax, pneumothorax and fractured ribs. www.indiandentalacademy.com
  34. 34. FLAIL CHEST This occurs when a segment of the chest wall looses bony continuity with the rest of the thoracic cage, usually as a result trauma associated with multiple rib fractures. Associated pain with chest wall movement and underlying lung injury add to the patient’s hypoxia. www.indiandentalacademy.com
  35. 35. FLAIL CHEST Initial treatment includes adequate ventiliation, administration of humidified oxygen and fluid resuscitation. Definitive treatment - re-expand the lung, ensure oxygenation, administer fluids and provide analgesia to improve ventilation. www.indiandentalacademy.com
  36. 36. OPEN PNEUMOTHORAX Large defects of the chest wall which remain open result in an open pneumothorax. If the opening in the chest wall is approximately two-thirds the diameter of the trachea, air passes preferentially through the chest defect with each respiratory effort. Effective ventilation is thereby impaired, leading to hypoxia www.indiandentalacademy.com
  37. 37. OPEN PNEUMOTHORAX Initial management is by promptly closing the defect with a sterile occlusive dressing large enough to overlap the wound's edges that is taped securely on three sides which provides a flutter - type valve effect. A chest drain should be placed remote from the site as soon as possible. Definitive surgical closure later. www.indiandentalacademy.com
  38. 38. TENSION PNEUMOTHORAX Tension pneumothorax develops when a one way valve air leak occurs either from the lung or through the chest wall. Air is forced into the thoracic cavity, between the parietal and visceral pleura, without any means of escape, completely collapsing the affected lung. www.indiandentalacademy.com
  39. 39. TENSION PNEUMOTHORAX Chest pain Air hunger Respiratory distress Tachycardia Hypotension Tracheal deviation Unilateral absence of breath sounds Neck vein distention and Cyanosis - late manifestation. www.indiandentalacademy.com
  40. 40. TENSION PNEUMOTHORAX It requires immediate decompression by inserting a large bore needle into the second intercostal space in the midclavicular line of the affected hemithorax. Definitive treatment requires the insertion of a chest drain into the fifth intercostal space (nipple level) between the anterior and midaxillary lines www.indiandentalacademy.com
  41. 41. MASSIVE HEMOTHORAX This results from a rapid accumulation of more than 1500 ml blood in the chest cavity. It is most commonly caused by a penetrating wound that disrupts the systemic or hilar vessels but can also result from blunt trauma. lt is discovered when shock is associated with the absence of breath sounds and/or dullness to percussion on one side of the chest. It is initially managed by a simultaneous restoration of blood volume and decompression of the chest cavity. www.indiandentalacademy.com
  42. 42. CARDIAC TAMPONADE Cardiac tamponade results commonly from penetrating injuries, but blunt injury may also cause the pericardium to fill with blood from the heart, great vessels or pericardial vessels. Pericardiocentesis, may result in immediate improvement. Definitive treatment - pericardiotomy www.indiandentalacademy.com
  43. 43. CIRCULATION WITH HEMORRHAGE CONTROL Shock is defined as an abnormality of the circulation that results in inadequate organ perfusion and tissue oxygenation. If unchecked this will lead to end organ dysfunction. Hemorrhage is the main cause of post injury deaths that are preventable by rapid treatment in the hospital setting. Hypotension following injury must be considered to be hypovolemic in origin until proved otherwise. www.indiandentalacademy.com
  44. 44. Classification and signs of hypovolemic shock (in an adult assuming a 70 kg patient with normally 5 litres of circulating volume) www.indiandentalacademy.com
  45. 45. HEMORRHAGE Hemorrhage is an acute loss of circulating blood volume. After airway and breathing, the initial treatment of shock is directed toward restoring cellular and organ perfusion with adequately oxygenated blood. www.indiandentalacademy.com
  46. 46. MANAGEMENT OF HEMORRHAGE The priority is to control the source of hemorrhage. External hemorrhage - controlled by direct manual pressure. Occult hemorrhage - immediate surgical intervention. www.indiandentalacademy.com
  47. 47. FLUID REPLACEMENT The aim of fluid management in hypotensive resuscitation - restore critical organ perfusion. Therefore in a standard adult trauma victim, 2 litres of warmed crystalloid, preferably Ringer's lactate, should be given and then the patient reassessed. In reassessing the circulatory state, one of three responses are seen :- Responder, Transient responder and non responder www.indiandentalacademy.com
  48. 48. BLOOD REPLACEMENT Either whole blood or packed cells can he used to resuscitate the trauma patient. The main purpose in transfusing blood is to restore the oxygen-carrying capacity of the intravascular volume. Volume resuscitation itself can be accomplished with crystalloids. www.indiandentalacademy.com
  49. 49. DISABILITY (NEUROLOGICAL EVALUATION) A rapid evaluation is performed at the end of the primary survey and this establishes the level of the patient's consciousness, as well as pupillary size and reaction. The Glasgow Coma Scale (GCS) is a detailed, quick, simple and predictive of patient outcome. www.indiandentalacademy.com
  50. 50. GLASGOW COMA SCALE www.indiandentalacademy.com
  51. 51. Exposure and environment The patient should be completely undressed to facilitate a thorough examination and assessment. After the assessment is completed it is important to cover the patient with warm blankets or an external warming device to prevent hypothermia. Intravenous fluids should be warmed before infusion. www.indiandentalacademy.com
  52. 52. Secondary survey This does not begin until the primary survey has been completed and the patient stabilized. It is a head to toe and front to back evaluation of the trauma patient. A thorough history and physical examination, including a reassessment of all vital signs, are carried out and each region of the body is completely examined. www.indiandentalacademy.com
  53. 53. HISTORY A through history should be taken from the patient and family. Allergies Medications currently used Past illness Pregnancy Last meal Events/ environment relating to injury www.indiandentalacademy.com
