DETERMINING THE NEED FOR PATIENT TRANSFER

Page 6: Resuscitation and transportation of trauma patients

RAPID PRIMARY SURVEY

• IDENTIFY LIFE THREATENING INJURIES in orderly manner based on effect of injury on patients physiology and life

• INITIATE LIFE PRESERVING THERAPIES • In settings with limited resources, the primary survey simplifies

priorities and any problems identified should be managed immediately, in the order they are detected, before moving on to the next step of the survey.

• However, at major trauma centers, many capable clinicians may be present, allowing the team to address multiple problems simultaneously.

Page 7: Resuscitation and transportation of trauma patients

The primary survey consists of the following steps:●Airway assessment and protection (maintain cervical spine stabilization when appropriate)●Breathing and ventilation assessment (maintain adequate oxygenation)●Circulation assessment (control hemorrhage and maintain adequate end-organ perfusion)●Disability assessment (perform basic neurologic evaluation)●Exposure, with environmental control (undress patient and search everywhere for possible injury, while preventing hypothermia)

RECOGNITION OF AIRWAY COMPROMISE• Maxillofacial Trauma• Neck Trauma• Laryngeal Trauma Agitation,obtundation Cyanosis indicates hypoxemia. However, cyanosis is a late finding of hypoxia. Pulse oximetry is used early in the airway assessment to detect inadequate oxygenation prior to the development of cyanosis. LOOK FOR retractions, use of accessory muscles LISTEN FOR abnormal sounds. Noisy breathing,Snoring, gurgling, and stridor FEEL FOR the location of the trachea.

• Tension pneumothorax• Open pneumothorax• Massive hemothorax• Flail chestNEEDS TO BE IDENTIFIED AT THIS STAGE OF PRIMARY SURVEY

• Ventilation requires functioning lungs, chest wall, diaphragm.

• Tachypnea can indicate respiratory distress

• Patients chest to be exposed to assess chest wall excursion.

• Palpate to detect chest wall injuries that compromise ventilation.

• Percuss to demonstrate air or blood.

Page 17: Resuscitation and transportation of trauma patients

RECOGNITION OF BREATHING COMPROMISE1] Ventilation can be compromised by airway obstruction, altered ventilatory mechanics, and/or central nervous system (CNS) depression. If a patient’s breathing is not improved by clearing the airway, other causes of the problem must be found and managed.

2] Direct trauma to the chest, especially with rib fractures,

3] Intracranial injury 4] Cervical spinal cord injury

Page 18: Resuscitation and transportation of trauma patients

OXYGENATION IS IT ADEQUATE?

Pulse oximetry is useful, as the continuous monitoring of oxygen saturation provides an immediate assessment of therapeutic interventions.• Oxygenated inspired air is best provided via a tightfitting oxygen

reservoir face mask with a flow rate of at least 11 L/min. Other methods (e.g., nasal catheter, nasal cannula, and nonrebreather mask) can improve inspired oxygen concentration

Page 19: Resuscitation and transportation of trauma patients

Circulation with hemorrhage control

• First step is to identify the presence of shock.• The second step in the initial management of shock is to identify the

probable cause of the shock state

DAMAGE CONTROL RESUSCITATION• PERMISSIVE HYPOTENSION • HEMOSTATIC RESUSCITATION• DAMAGE CONTROL SURGERY

Page 25: Resuscitation and transportation of trauma patients

PERMISSIVE HYPOTENSION• Target SBP of 70-90 mm hg [ palpable radial pulse]• BY RESTRICTED OR DELAYED APPROACH TO FLUID ADMINISTRATION.• Aggressive fluid administration as ineffective and potentially harmful.• Controlled hypotension may be beneficial in patients with

hemorrhagic shock. However, it may be detrimental to blunt trauma patients with brain injury, as hypotension reduces cerebral perfusion and increases mortality.

• The rationale for improved outcomes with delayed fluid resuscitation is that aggressive fluid administration might, via augmentation of blood pressure, dilution of clotting factors, and production of hypothermia, disrupt thrombus formation and enhance bleeding.

Page 26: Resuscitation and transportation of trauma patients

INITIAL MANAGEMENT OF HEMORRHAGIC SHOCKThe initial treatment of shock is directed toward restoring cellular and organ perfusion with adequately oxygenated blood.• Definitive control of hemorrhage and restoration of adequate

circulating volume are the goals of treatment of hemorrhagic shock.• External haemorrhage is identified and controlled in primary survey(MANUAL COMPRESSION, SPLINTS, ELASTIC BANDAGE, TORNIQUET)• Vasopressors are contraindicated for the treatment of hemorrhagic

shock because they worsen tissue perfusion.

Page 27: Resuscitation and transportation of trauma patients

• Short, large-caliber peripheral intravenous lines are preferred• The most desirable sites for peripheral, percutaneous intravenous

lines in adults are the forearms and antecubital vein• If circumstances prevent the use of peripheral veins, large-caliber,

central venous (i.e., femoral, jugular, or subclavian vein. • In children younger than 6 years, the placement of an intraosseous

needle should be attempted before inserting a central line.

Page 28: Resuscitation and transportation of trauma patients

INITIAL FLUID THERAPY• An initial, warmed fluid bolus is given. The usual dose is 1 to 2 L for

adults and 20 mL/kg for pediatric patients.• ISOTONIC CRYSTALLOIDS(NS,RL,plasmalyte-A ), Hypertonic saline,

RESTRICTIVE VS LIBERAL FLUID ADMINISTRATION

•  Aggressive fluid administration via augmentation of blood pressure, dilution of clotting factors, and production of hypothermia, disrupt thrombus formation and enhance bleeding.

• Patient’s mental status and likelihood of intracranial injury, type of injury, severity of injury (eg, ongoing hemorrhage), and proximity to a trauma center to be considered.

• Aggressive fluid administration as ineffective and potentially harmful. and limited volume replacement that maintains minimally adequate organ perfusion improve outcomes. This strategy is often referred to as delayed fluid resuscitation or controlled hypotension, an approach which targets early fluid resuscitation only to a systolic blood pressure of 70 – 90 mmHg.[ palpable radial pulse]

Page 33: Resuscitation and transportation of trauma patients

HEMOSTATIC RESUSCITATION1] Early use of blood and blood products as primary resuscitation fluids to treat ATC and prevent development of dilutional coagulopathy.2] Aggressive hemostatic resuscitation to be equally combined with aggressive control of bleeding.3] Transexamic acid 1g over 10 min f/b 1g over 8hours when given within 1 hr for uncontrollable bleeding who required blood transfusion were benefited. As per CRASH2 trial in 2010 transexaemic acid significantly reduced mortality due to haemorrhage without any increase of Thrombo-embolic complications. 4] factor7,prothrombin complex, fibrinogen concentrates also play a role in hemostatic resuscitation.

Page 34: Resuscitation and transportation of trauma patients

BLOOD TRANSFUSION• The decision to initiate blood transfusion is based on the patient’s response, as

described in the previous section. • Patients who are transient responders or nonresponders—those with Class III or

Class IV hemorrhage—will need pRBCs and blood products as an early part of their resuscitation.

• CROSSMATCHED, TYPE-SPECIFIC, AND TYPE O BLOOD• Fully crossmatched blood is preferable. However,the complete crossmatching

process requires approximately 1 hour in most blood banks. • Type-specific blood can be provided by most blood banks within 10 minutes. Such

blood is compatible with ABO and Rh blood types, but incompatibilities of other antibodies may exist.

• If type-specific blood is unavailable, type O negative packed cells are indicated for patients with exsanguinating hemorrhage.

Page 35: Resuscitation and transportation of trauma patients

RBC:PLATELET:FFP------1:1:1 or 2:1:1 ?

• PROPPR trial and PROMMTT study showed that early use of higher amounts of plasma and platelets was associated with improved survival during first 6 hours after admission.

• Early availability of blood products administerd within minutes of arrival using transfusion ratio of 1:1:1 was associated with better hemostasis ad decreased hemorrhage related death.

Page 36: Resuscitation and transportation of trauma patients

DAMAGE CONTROL SURGERY• Concept in which initial surgery becomes a part of resuscitation

process rather than curative process.• Aimed at restoring normal physiology rather than anatomical integrity• 3parts initial abbreviated laparotomy, ICU resuscitation, and

subsequent reoperation for definitive resuscitation.• Only when patient is physiologically stable final therapeutic surgery is

carried out.

Exposure and environmental controlCompletely undressed and entire body is examined for signs of injury during the primary survey Missed injuries pose a grave threat Regions often neglected include the scalp, axillary folds, perineum, gluteal folds and in obese patients, abdominal folds. • While maintaining cervical spine precautions, examine the patient's back.• Hypothermia should be prevented if possible and treated immediately once

identified.• department (ED) and operating room (OR) temperatures of at least 29.4°C

(85°F) during the treatment of these patients• Make liberal use of warm blankets and active external warming devices.

DIAGNOSTIC STUDIES• Portable x-rays• Ultrasound (FAST exam) & Extended FAST (E-FAST)• Diagnostic peritoneal tap or lavage• Electrocardiogram• Laboratory tests

Page 40: Resuscitation and transportation of trauma patients

X-rays

• Screening x-rays should be obtained, either in the emergency department (ED) or the operating room (OR), even in hemodynamically compromised patients who are sent directly to the OR during or after their primary survey.

• Prompt imaging of the lateral cervical spine, chest, and pelvis can detect life threatening injuries that might otherwise be missed.

• A plain radiograph of the chest should be obtained in patients with penetrating injuries of the chest, back, or abdomen regardless of the need for CT. Plain films may reveal sub-diaphragmatic free air, a foreign body, or a pneumothorax or haemothorax

Page 41: Resuscitation and transportation of trauma patients

FAST• Primarily to detect pericardial and intra-peritoneal bleed.• Reliably identifies 200-250ml of intra-peritoneal fluid Sensitivity/specificity: 75%/98% Performed using a curvilinear 2.5 or 3.5 MHz probe• Cardiac: parasternal or sub-xiphoid, hepato-cardiac interface, pericardial space. RUQ: hepato-renal interface (Morrison’s Pouch), diaphragm, inferior pole of kidney.LUQ: spleno-renal interface, diaphragm, inferior pole of kidney, inferior tip of spleen.Suprapubic: outline of bladder, silhouette of uterus (females).Cannot reliably evaluate retro-peritoneal structure/hollow viscous injury/ pelvic bleeding[cannot differentiate urine or blood]

• Unstable patient: FAST >>>>>>>> OR. Stable : abdominal CT is gold standard

Page 42: Resuscitation and transportation of trauma patients

Diagnostic Peritoneal Lavage (DPL)• Open or closed (Seldinger) approach • It can be performed to detect intra-peritoneal blood when FAST is

unavailable, to determine the type of intra-peritoneal fluid when it is important to do so (eg, blood vs urine in the setting of a pelvic fracture)

• Highly accurate for hemo-peritoneum (Sn = 95%, Sp = 99%)• Laparotomy when:

• 10 cc gross blood• Enteric contents• 1 L warmed NS: > 100 000 RBC / mm3 or > 500 WBC / mm3

• High Sn for hollow viscous injuries [More so than CT]• Retro-peritoneum can’t be assessed • High false positive DPL with pelvic fracture• A negative aspirate in an unstable patient with a pelvic fracture suggests

retroperitoneal hemorrhage, and angiography with possible embolization should ensue

Page 43: Resuscitation and transportation of trauma patients

Computerized Tomography• It is a time-consuming procedure that should be used only in hemodynamically normal

patients.• Sn = 92-97%, Sp = 99% for bleeding• Only modality to directly detect retroperitoneal injury

• CT scanning's benefits include: Detects not only the presence but the source and amount of hemo-peritoneum Active bleeding often detectable Retro-peritoneum and vertebral column can be assessed

• CT scanning's disadvantages include: Suboptimal sensitivity for pancreatic, diaphragmatic, bowel, and mesentery injury. Can be unobtainable or harmful to obtain in unstable patients

Page 44: Resuscitation and transportation of trauma patients

SECONDARY SURVEY• A secondary survey is performed in all trauma patients determined to be

stable upon completion of the primary survey. The secondary survey includes a

Detailed history[ AMPLE],Detailed Head to Toe examination, Targeted diagnostic studies plays a crucial role in avoiding missed injuriesTERTIARY SURVEY < 24 hours & prior to discharge.• Identifies and catalogues all injuries after the initial resuscitation and

operative intervention . The timing of this survey typically occurs within twenty four hours after admission and is repeated when the patient is awake, responsive, and able to communicate any complaints & prior to discharge.

HEAD INJURY• The primary goal of treatment for patients with suspected traumatic

brain injury (TBI) is to prevent secondary brain injury.

• Secondary injury may occur due to hypotension, hypoxia, hypercapnia, and iatrogenic hypocapnia.

Page 49: Resuscitation and transportation of trauma patients

MANAGEMENT OF HEAD INJURIES 1] Adequate oxygenation (PaO2 >60 mmHg) and blood pressure support (systolic BP >90 mmHg) Isotonic fluids (normal saline) should be used to maintain euvolemia. A subgroup analysis in the large SAFE study found that for patients with TBI, fluid resuscitation with albumin was associated with a higher mortality as compared with normal saline (33 versus 20 percent); this risk was even more pronounced in those with severe TBI (42 versus 22 percent)

2] Early endotracheal intubation is generally recommended for patients with a Glasgow coma scale score of 8 or less3] Management of raised ICP ventriculostomy placement with ICP monitoring in patients with severe TBI and an abnormal CT scan showing evidence of mass effect from lesions such as hematomas, contusions or swelling

Page 50: Resuscitation and transportation of trauma patients

4] CPP target is 60 mmHg, avoiding CPP >70 mmHg and <50 mmHg, which should be achieved by optimizing ICP first and then MAP (with volume expansion, vasopressors) second5] Short-term (one week) use of antiepileptic drugs ( phenytoin , valproate ) for the prevention of early seizures 6] fever and hyperglycemia be avoided for their potential to exacerbate secondary neurologic injury. Coagulopathy should be corrected to maintain an INR < 1.4 and a platelet count > 75,000/mm 3 . 7] SURGICAL TREATMENT OF INTRA CRANIAL HAEMORRAGES PENETRATING INJURIES, SKULL FRACTURES, DECOMPRESSIVE CRANIECTOMY

Page 53: Resuscitation and transportation of trauma patients

Mannitol· Use with signs of tentorial herniation· Dose: 0.25-1.0 g / kg IV bolus• Consult with neurosurgeon first• Mannitol should not be given to patients with hypotension, because

mannitol does not lower ICP in hypovolemia and is a potent osmotic diuretic. This can further exacerbate hypotension and cerebral ischemia.

Hypertonic saline 2-6ml/kg bolus is also used to reduce elevated ICP.Concentrations of 3% to 23.4% are used, and this may be the preferable agent to use in patients with hypotension, as it does not act as a diuretic. However, thereis no difference between mannitol and hypertonic salinein lowering ICP

Page 54: Resuscitation and transportation of trauma patients

•Hyperventilation should be used only in moderation and for as limited a period as possible

• hypercarbia (PCO2 > 45mm Hg) will promote vasodilation and increase intracranial pressure, and thus it should be avoided.

• Hyperventilation will lower ICP in a deteriorating patient with expanding intracranial hematoma until emergent craniotomy

• Aggressive and prolonged hyperventilation may promote cerebral ischemia in the already injured brain by causing severe cerebral vasoconstriction and thus impaired cerebral perfusion. This is particularly true if the PaCO2 is allowed to fall below 30 mm Hg

SPINAL SHOCK

• Spinal shock refers to the flaccidity (loss of muscle tone) and loss of reflexes seen after spinal cord injury.

• The “shock” to the injured cord may make it appear completely nonfunctional, although the cord may not necessarily be destroyed.

• The duration of this state is variable.

INTRAVENOUS FLUIDS in spinal trauma 1] Intravenous fluids are administered as they would usually be for resuscitation of trauma patients. 2] If active hemorrhage is not detected or suspected, persistent hypotension should raise the suspicion of neurogenicshock. 3] Patients with hypovolemic shock usually have tachycardia, whereas those with neurogenic shock classically have bradycardia. If the blood pressure does not improve after a fluid challenge, use of DOPAMINE is usually the vasopressor of choice.

Resuscitative Thoracotomy The therapeutic maneuvers that can be effectively accomplished with a resuscitative thoracotomy are:1] Evacuation of pericardial blood causing tamponade2] Direct control of exsanguinating intrathoracic hemorrhage3] Open cardiac massage4] Cross-clamping of the descending aorta to slow blood loss below the diaphragm and increase perfusion to the brain and heart.

Page 73: Resuscitation and transportation of trauma patients

Abdominal and Pelvic Trauma

ASSESMENT AND MANAGEMENT1] Inspect the abdomen and flanks for lacerations, contusions and ecchymosis; palpate for tenderness and rigidity. The presence of a seat belt sign, rebound tenderness, abdominal distension, or guarding all suggest intra-abdominal injury.2] Rectum and genitourinary — Inspect the perineum of all patients for signs of injury3] DRE is warranted in cases where urethral injury or penetrating rectal injury is suspected. If the examination is performed, check for the presence of gross blood (sign of bowel injury), a high-riding prostate (sign of urethral injury), abnormal sphincter tone (sign of spinal cord injury), and bone fragments (sign of pelvic fracture).

• Reduce fracture, Stabilize pelvis• Splint fracture

• Application of direct pressure [if bleeding]

• Use of a tourniquet may be helpful and lifesaving [ severe bleed]• Appropriate fluid resuscitation [ prevents crush syndrome]

• All constrictive dressings, casts, and splints applied over the affected extremity must be released[ in compartment syndrome]

If no significant changes occur, fasciotomy is required

TRANSFER OF TRAUMA PATIENTS

Page 78: Resuscitation and transportation of trauma patients

Determining the Need for Patient Transfer It is essential that clinicians assess their own capabilities and limitations, as well as those of their institution, to allow for early differentiation between patients who may be safely cared for in the local hospital and those who require transfer for definitive care.

TIMELINESS OF TRANSFER When should I transport the patient?

Patient outcome is directly related to the time elapsed between injury and properly delivered definitive care. In institutions in which there is no full-time, in-house emergency department (ED) coverage, the timeliness of transfer is partly dependent on the how quickly the doctor on call can reach the ED. In addition, the attending doctor must be committed to respond to the ED prior to the arrival of critically injured patients.

WHOM DO I TRANSFER?CATEGORY SPECIFIC INJURY &OTHER FACTORS

CNS – Penetrating injury or depressed skull fracture – Open injury with or without cerebrospinal fluid (CSF) leak – GCS score <15 or neurologically abnormal – Lateralizing signs• Spinal cord injury or major vertebral injury

CHEST • Widened mediastinum or signs suggesting great vessel injury• Major chest wall injury or pulmonary contusion• Cardiac injury• Patients who may require prolonged ventilation

PELVIS/ABDOMEN • Unstable pelvic-ring disruption• Pelvic-ring disruption with shock and evidence of continuing hemorrhage• Open pelvic injury• Solid organ injury

EXTREMITIES • Severe open fractures• Traumatic amputation with potential for replantation• Complex articular fractures• Major crush injury• Ischemia

MULTI SYSTEM INJURIES • Head injury with face, chest, abdominal, or pelvic injury• Injury to more than two body regions• Major burns or burns with associated injuries• Multiple, proximal long-bone fractures

Page 80: Resuscitation and transportation of trauma patients

SECONDARY DETERIORATION Mechanical ventilation required• Sepsis• Single or multiple organ system failure (deterioration in central nervous, cardiac, pulmonary, hepatic, renal, or coagulation systems)• Major tissue necrosis

CO MORBID FACTORS ELDERLY, CHILD<5, DM, CARDIC DISEASE, RESPIRATORY DISEASE, PREGNANCY, MORBID OBESITY, IMMUNOSUPPRESSION

Patients with evidence of shock, Significant physiologic deterioration, or progressiveDeterioration in neurologic status require the highestLevel of care and will likely benefit from timely transfer

Page 81: Resuscitation and transportation of trauma patients

The inter-hospital transfer of a critically injured patient is potentially hazardous unless the patient’s condition is optimally stabilized before transport, transfer personnel are properly trained, and provision has been made for managing unexpectedcrises during transport.

Page 82: Resuscitation and transportation of trauma patients

TREATMENT PRIOR TO TRANSFER

• Patients should be resuscitated and attempts made to stabilize their conditions as completely as possible based on the following suggested outline:

• 1. Airwaya. Insert an airway or endotracheal tube, if needed.b. Provide suction.c. Insert a gastric tube to reduce the risk of aspiration.• 2. Breathinga. Determine rate and administer supplementary oxygen.b. Provide mechanical ventilation when needed.c. Insert a chest tube if needed.• 3. Circulationa. Control external bleeding.b. Establish two large-caliber intravenous lines and begin crystalloid solution infusion.c. Restore blood volume losses with crystalloid fluids or blood and continue replacement during transfer.d. Insert an indwelling catheter to monitor urinary output.e. Monitor the patient’s cardiac rhythm and rate.

Page 83: Resuscitation and transportation of trauma patients

4. Central nervous system a. Assist respiration in unconscious patients. b. Administer mannitol, if needed.

c. Immobilize any head, neck, thoracic, and lumbar spine injuries. 5.Diagnostic studies When indicated; obtaining these studies should not delay transfer

6. Wounds Performing these procedures should not delay transfer.

7. Fractures Apply appropriate splinting and traction.

Page 84: Resuscitation and transportation of trauma patients

TREATMENT DURING TRANSPORT• The appropriate personnel should transfer the patient, based on

the patient’s condition and potential problems.• Treatment during transport typically includes: 1.Monitoring vital signs and pulse-oximetry2.Continued support of cardio-vascular system3.Continued blood-volume replacement4.Use of appropriate medications as ordered by a doctor or as allowed by written protocol5.Maintenance of communication with a doctor or institution during transfer6.Maintenance of accurate records during transfer

PITFALL: ET tubes, IV cannulas may get dislodged during transport. Necessary equipments to be ready for the procedure.

Page 85: Resuscitation and transportation of trauma patients

 Establishment of transfer agreements provide for the consistent and efficient movement of patients between institutions, and enhance the efficiency and quality of the patient’s treatment during transfer.

Page 86: Resuscitation and transportation of trauma patients

Transfer responsibilities are held by both referring and receiving doctor

• REFERRING DOCTORThe referring doctor is responsible for initiating transfer of the patient to the receiving institution and selecting the appropriate mode of transportation and level of care required for optimal treatment of the patient

• Stabilizing the patient’s condition before transfer to another facility is the responsibility of the referring doctor, within the capabilities of his or her institution.

• Initiation of the transfer process should begin while resuscitative efforts are in progress.

• Transfer agreements must be established to provide for the consistent and efficient movement of patients between institutions.

• PITFALLInappropriate communication b/w Referring and accepting care providers resulting in loss of information critical to the patient’s care.

Page 87: Resuscitation and transportation of trauma patients

RECEIVING DOCTOR1.The receiving doctor must be consulted with regard to the transfer of a trauma patient.2.The receiving doctor should assist the referring doctor in making arrangements for the appropriate mode and level of care during transport.3. If the proposed receiving doctor and facility are unable to accept the patient, they should assist in finding an alternative placement for the patient.4. Only by direct communication between the referring and receiving doctors can the details of patient transfer be clearly delineated. 5.If adequately trained emergency medical personnel are not available, a nurse or doctor should accompany the patient. 6.All monitoring and management rendered en route should be documented.

Page 88: Resuscitation and transportation of trauma patients

MODES OF TRANSPORTATION• Do no further harm is the most important principle when choosing

the mode of patient transportation. • Ground, water, and air transportation can be safe and effective in

fulfilling this principle, and no one form is intrinsically superior to the others.

• Local factors such as availability , geography, cost, and weather are the main determining factors as to which to use in a given circumstance.

• PITFALLfailure to anticipate deterioration in the patient’s neurologic condition or hemodynamic status during transport
