2 Aims & Learning Outcomes Aims & Learning Outcomes The aim of this module is to describe and apply the airway, breathing, circulation, disability and exposure (ABCDE) approach and SBAR to acutely ill patients The learning outcomes are to: Describe the clinical assessments of each element of the ABCDE approach. Apply the appropriate methods of oxygen and fluid delivery to acutely ill patients. Perform (using manikin) and reflect on the bedside application of the ABCDE approach to a patient with an acute ST elevation myocardial infarction, a patient with sepsis and a patient with an acute gastrointestinal haemorrhage Perform using role play the situation, background, assessment, and recommendation (SBAR) approach for referral of acutely ill patients Reflect on own learning and recognise how improvements can be made.

3 AIRWAY BREATHING CIRCULATION DISABILITY EXPOSURE Recognition & Early Management of Acutely Ill Patients Introduction Introduction The General Medical Council expects that by qualification junior doctors will be able to provide immediate care in medical emergencies; specifically that the junior doctor will be able to: Assess and recognise the severity of a clinical presentation and a need for immediate emergency care. (Outcomes for Graduates 2015) Acutely ill patients are best approached using an ABCDE assessment in conjunction with a targeted history and examination in order to reach a diagnosis so that definitive treatment can be administered. A B C D E

4 Bedside Assessment of Acutely Ill Patients Bedside Assessments of Acutely Ill Patients The clinical management of acutely ill patients requires that life threatening problems are immediately addressed whilst a diagnosis is sought so that definitive treatment can be administered. The ABCDE approach and diagnostic synthesis are complementary and simultaneous processes (see next slide). Junior doctors can co-ordinate these activities by proceeding in a step wise fashion.

5 Bedside Assessment of Acutely Ill Patients

6 Step 1 Step 1: Initial Assessment Much of the ABCDE assessment can be accomplished within moments of arrival at the bedside by observation of the patient and their charts. Offering a handshake is a good way to start the bedside assessment, not only will this provide clinical information about the level of consciousness, airway patency and peripheral perfusion but will also reassure a potentially frightened and distressed patient. Diagnosis requires a focussed history, examination and investigations history from the patient may be limited and may need to be supplemented by information obtained from the bedside nurse, medical notes and relatives. The ABCDE approach requires that concerns regarding each element of this bedside assessment have to be addressed before proceeding to the next element. For example, an obstructed airway must be opened before breathing is assessed.

7 AIRWAY Recognition & Early Management of Acutely Ill Patients Step 2 BREATHING CIRCULATION DISABILITY EXPOSURE Step 2: Airway Assessment Complete airway obstruction is very rare (patients usually dies within minutes) but partial airway obstruction is quite common and can be recognised by noisy breathing such as snoring or gurgling and evidence of increased work of breathing such as intercostal recession. The commonest cause of partially obstructed airway is a reduced level of consciousness (due to reduced airway muscular tone, loss of protective airway reflexes, principally the gag and cough reflexes, retention of oropharyngeal secretions and tongue mal-position). A A partially obstructed airway can be relieved with simple manoeuvres such as head tilt & chin lift or jaw thrust. Airway adjuncts such as oropharyngeal or nasopharyngeal devices may be useful. B C D E

8 Simple Airway Manoeuvres Head tilt & Chin lift Tilt head backwards by placing one hand on patient`s forehead. Gently lift lower jaw by placing finger tips of other hand under patient`s lower jaw. Jaw thrust Tilt head back. With fingers placed behind lower jaw apply steady pressure to lift lower jaw forward. At same time open mouth slightly by displacing chin in downwards direction using thumbs. Pictures are from the ALERT Course Manual Third Edition January 2012 Portsmouth Hospitals NHS Trust

9 AIRWAY Recognition & Early Management of Acutely Ill Patients Step 3 BREATHING CIRCULATION DISABILITY EXPOSURE Step 3: Breathing Assessment Begin by counting respiratory rate, breaths per minute (bpm). Increased respiratory work commonly accompanies acute illness as a result of an increased metabolic rate and oxygen consumption. This may lead to respiratory distress, signs of which include: inability to complete sentences, high respiratory rate, diaphoresis, accessory muscle use and cyanosis. Focussed clinical examination including tracheal palpation, percussion and auscultation may uncover the diagnosis. (Tracheal deviation-tension pneumothorax, hyper-resonance-tension pneumothorax, dull percussion note-pleural effusion/empyema, wheeze, silent chest-acute severe asthma, left ventricular failure, diminished or bronchial breath sounds-pneumonia). A B C D E

10 AIRWAY Recognition & Early Management of Acutely Ill Patients Step 3 BREATHING CIRCULATION DISABILITY EXPOSURE Step 3: Breathing Assessment High flow oxygen should be administered to all acutely ill patients the effects of therapy should be assessed using pulse oximetery and the target oxygen saturations should be between 94% and above. The appropriate oxygen delivery device to use is an oxygen mask with reservoir bag. The reservoir bag should be inflated by placing a finger over the valve before applying on the patient. It is vital that the reservoir is kept inflated at all times this is usually achieved by setting the flow rate of oxygen to 15 L/min. This mask will usually deliver an inspired oxygen concentration (FiO 2 ) of 60-85% A B C D E

11 AIRWAY Recognition & Early Management of Acutely Ill Patients Step 4 BREATHING CIRCULATION DISABILITY EXPOSURE Step 4: Circulatory Assessment Begin by assessing radial pulse, beats per minute (bpm), rhythm and character. Attach cardiac monitoring if available. Note the blood pressure. Clinical signs that are common to hypovolaemic, obstructive and cardiogenic shock include: Confusion or agitation Cold extremities Reduced capillary refill Tachycardia Absent or small volume peripheral pulses Hypotension Oliguria A B C D E

12 AIRWAY Recognition & Early Management of Acutely Ill Patients Step 4 BREATHING CIRCULATION DISABILITY EXPOSURE Step 4: Circulatory Assessment The jugular venous pulse may be useful in distinguishing between hypovolaemic states (low) and cardiogenic or obstructive shock (elevated). Circulatory features of septic shock may include warm peripheries (vasodilatation) and bounding pulse. With the exception of cardiogenic shock, complicated by pulmonary oedema, the management of shocked patients invariably requires the administration of intravenous fluid. Peripheral cannulae can usually be inserted into antecubital fossa or external jugular veins whilst central lines provide access into internal jugular, subclavian and femoral veins. Very rarely venous access may require a senior to perform a cut-down approach or an intraosseous approach may be needed if venous access cannot be obtained. A B C D E

13 Poiseuille s Law Recognition & Early Management of Acutely Ill Patients Step 4 Step 4: Circulatory Assessment Sizes of peripheral cannula are determined by gauge (12 largest, 14, 16, 18, 20, 22, 24 smallest). Poiseuille s law states that flow is inversely related to the length of the IV catheter and directly related to its radius to the fourth power. Therefore fluids flow fastest down short cannula with large diameter. Two 16-gauge lines are recommended for resuscitation. Flow Rate Pressure Radius Fluid Viscosity Length of Tubing Administer intravenous fluids if hypotensive. Bolus of 500 ml of crystalloid (containing sodium in the range of mmol/l) over 15 minutes. (NICE IV Fluid Therapy Guidelines 2013).

14 AIRWAY Recognition & Early Management of Acutely Ill Patients Step 5 BREATHING CIRCULATION DISABILITY EEXPOSURE Step 5: Disability Assessment Disability refers to neurological status, relevant clinical examination would include assessment of the level of consciousness, focal and localising neurological signs, pupillary reflexes and signs of meningism.

16 AIRWAY Recognition & Early Management of Acutely Ill Patients Step 6 BREATHING CIRCULATION DISABILITY EXPOSURE Step 6: Exposure Assessment Exposure is a prompt to ensure the body is examined as a whole. Pay attention to wound sites or other injuries on the body. During examination, be mindful of environmental temperature and potential adverse effects of cooling (shivering causes increased metabolic work and contributing to further cardiovascular decompensation). Assess body temperature. A B C D E

17 Step 7 Step 7: Diagnostic synthesis, investigation and definitive management Once diagnosis is obtained and/or the causes of deterioration understood, definitive treatment can be started. This may require transfer of the patient to the operating theatre, interventional cardiology laboratory, endoscopy suite, intensive care unit or high dependency unit. Transfer will need to be conducted by trained personnel and the proposed management carefully communicated to the patient and those close to the patient.

18 Referral Referral of Acutely Ill Patient using the SBAR Approach Following the bedside assessment it is likely that the junior doctor will need to discuss further management with a senior colleague. The NHS Institute for Innovation and Improvement has recommended the Situation, Background, Assessment and Recommendation (SBAR) approach for such communications. Identify yourself (name, role, location) Confirm the identity of the person you are speaking to Identify the patient (name, hosp no, age, sex, and location) State the problem S SITUATION B BACKGROUND Relate the history Date of admission Diagnosis Management Describe current interventions State NEWS score A,B,C,D,E assessment Any other relevant factors eg relevant physical examination, blood results, sepsis screening, pain A ASSESSMENT R RECOMMENDATION State the request e.g. I need you to see this patient urgently; please come to the ward immediately

19 Referral Referral of Acutely Ill Patient using the SBAR Approach Once SBAR handover has been conveyed ensure that the receiver of this information understands the information and the urgency of the call. It is useful to hear the receiver Recall:- Summarise what has been relayed Ask for further information if necessary Confirm when expected to review patient / or relay alternative plan
