The approach to the critically ill patient Assessment of the Critically Ill Patient Nick Smith Clinical Skills Khaled M.Hassan MD; 2011 A E B D C
Learning outcomes: • Identify the correct sequence of priorities in assessing the critically ill patient. • State why it is important to have a systematic approach to assessment and care, with rational for each step. • Identify clinical situations in which a patient’s condition may become compromised. • Demonstrate safe and effective assessment and care of the critically ill patient using a systematic approach. Khaled M.Hassan MD; 2011
ISIT IMPORTANT TO ASSESS? • Assessment is the first step in Caring for a patient, and assessing the critically ill patient is an essential part of their care. • Careful assessment is fundamental in order to recognise when a patient is becoming compromised. • The nurse acts as patient advocate, monitoring, anticipating potential problems, planning, implementing and constantly evaluating care, and communicating with other MDT; multidisciplinary team; staff involved in the patient care. • Khaled M.Hassan MD; 2011
The Multidisciplinary Team (MDT) • The MDT brings together people who are experts in different areas of medicine and care, and usually meet every week to discuss the diagnosis, treatment and care of individual patients. The Team is responsible for: • Working out your treatment plan • Deciding on further tests • Making appropriate referrals to specialist services • Making sure the team has all the necessary members • Collecting information and keeping good records. Khaled M. Hassan MD. 2011
Patient Assessment Systems • Basic Life support (BLS) • Advanced Life Support (ALS) • Acute Life-threatening Events, Recognition and Treatment (ALERT) • The Advanced Trauma Life Support (ATLS) Khaled M.Hassan MD; 2011
All of these assessment systems use a systematic approach in a strict order: • A: airway (with C-spine protection in trauma) • B: breathing • C: circulation • D: deficits in neurological status • E: environment (exposure) Khaled M.Hassan MD; 2011
Objectives • The rational of ABCDE • The process of primary & secondary survey • Recognition of life threatening events • Treatment of life-threatening conditions • Handover Khaled M. Hassan MD; 2011
The ABCDE approach A E B Airway & oxygenation D C Exposure & examination Breathing & ventilation Disability due to neurological deterioration Circulation & shock management
The principles • Perform primary ABCDE survey (5 min) • Instigate treatment for life threatening conditions as you find them • Re-assess when any treatment is completed • Perform more detailed secondary ABCDE survey including investigations • If condition deteriorates repeat primary survey Khaled M. Hassan MD; 2011
The primary survey • ABCDE assessment looking for immediately life threatening conditions • Rapid intervention usually includes max O2, IV access, fluid challenge +/- specific treatment • Should take no longer than 5 min • Can be repeated as many times as necessary • Get experienced help as soon as you need it Khaled M. Hassan MD; 2011
The secondary survey • Performed when patient more stable • More detailed examination of patient (ABCDE) • Order investigations to aid diagnosis • IF PATIENT DETERIORATES RETURN TO PRIMARY SURVEY Khaled M.Hassan MD; 2011
Airway • How do we assess airway and why? Khaled M. Hassan MD; 2011
Airway - causes A • GCS • Body fluids • Foreign body • Inflammation • Infection • Trauma Khaled M. Hassan MD; 2011
Airway - assessment A • Unresponsive • Added sounds • Snoring, gurgling, wheeze, stridor • Tracheal tug • Accessory muscles • See-saw respiratory pattern Khaled M. Hassan MD; 2011
Airway – interventions(basic) A • Head tilt chin lift • Jaw thrust • Suction • Oral airways • Nasal airways Khaled M. Hassan MD; 2011
Airway – interventions(advanced) A • GET HELP!!! • Nebulised adrenaline for stridor • LMA • Intubation • Cricothyroidotomy • Needle or surgical Khaled M.Hassan MD; 2011
Once airway open... A • Give 15 litres of oxygen to all patients via a non-rebreathing mask • For COPD patients re-assess after the primary survey has been complete & keep Sats 90-93% Khaled M. Hassan MD; 2011
Breathing • Why do we assess breathing and how do we carry out a comprehensive respiratory assessment? Khaled M. Hassan MD; 2011
Breathing - causes B • GCS • Resp depressions • Muscle weakness • Exhaustion • Asthma • COPD • Infection Khaled M. Hassan MD; 2011 • Pulmonary oedema • Pulmonary embolus • ARDS • Pneumothorax • Haemothorax • Open pneumothorax • Flail chest
Breathing - assessment B • Look • Rate (<10 or >20), symmetry, effort, SpO2, colour • Listen • Taking: sentences, phrases, words • Bilateral air entry, wheeze, silent chest other added sounds • Feel • Central trachea, Percussion, expansion Khaled M. Hassan MD; 2011
Breathing - interventions B • Consider ventilation with AMBU™ bag if resp rate < 10 • Position upright if struggling to breath • Specific treatment • i.e.: β agonist for wheeze, chest drain for pneumothorax Khaled M. Hassan MD; 2011
Circulation • What is the significance of circulation and how do we assess the patient? Khaled M. Hassan MD; 2011
Circulation - assessment • Look at colour • Examine peripheries • Pulse, BP & CRT • Hypotension (late sign) • sBP< 100mmHg • sBP < 20mmHg below pts norm • Urine output • Consider compensation mechanisms Khaled M. Hassan MD; 2011 C
Circulation – shock Inadequate tissue perfusion • Loss of volume • Hypovolaemia • Pump failure • Myocardial & non-myocardial causes • Vasodilatation • Sepsis, anaphylaxis, neurogenic C BP = HR x SV x SVR Khaled M.Hassan MD; 2011
Circulation - interventions • Position supine with legs raised • Left lateral tilt in pregnancy • IV access - 16G or larger x2 • +/- bloods if new cannula • Fluid challenge • colloid or crystalloid? • ECG Monitoring • Specific treatment Khaled M.Hassan MD; 2011 C
Central Venous Pressure • Involves insertion of a line to a major vein e.g. subclavian, internal jugular under full aseptic technique. • Patient is placed in supine or Trendelenburg position – promotes venous filling,aids catheter placement and reduces risk of air embolism. • Following insertion a check x-ray is required to confirm position and absence of pneumothorax. Khaled M. Hassan MD; 2011
CVP (contd.) • It is a direct measurement of pressure within the right atrium. • Readings should not be used in isolation, but as part of full haemodynamic assessment. • Used as a guide in fluid replacement. • Used to establish deficits in blood volume. • Used for drug administration, maintaining nutrition (TPN) Khaled M.Hassan MD; 2011
CVP (contd.) • What is the nursing management of CVP lines Khaled M.Hassan MD; 2011
Deficits in neurological status & environment (exposure) • How will you assess neurological status and environment? Khaled M. Hassan MD; 2011
Disability - causes • Inadequate perfusion of the brain • Sedative side effects of drugs • BM • Toxins and poisons • CVA • ICP Khaled M. Hassan MD; 2011 D
Disability - assessment • AVPU (or GCS) • Alert, responds to Voice, responds to Pain, Unresponsive • Pupil size/response • Posture • BM • Pain relief Khaled M. Hassan MD; 2011 D
Disability - interventions • Optimise airway, breathing & circulation • Treat underlying cause • i.e.: naloxone for opiate toxicity • Caution if reversing benzo’s • Treat BM • 100ml of 10% dextrose (or 20ml of 50% dextrose) • Control seizures • Seek expert help for CVA or ICP Khaled M. Hassan MD; 2011 D
Exposure E • Remove clothes and examine head to toe front and back • Haemorrhage (inc concealed), rashes, swelling etc • Keep warm (unless post cardiac arrest) • Maintain dignity Khaled M. Hassan MD; 2011
Secondary survey • Repeat ABCDE in more detail • History • Order investigations • ABG, CXR, 12 lead ECG, Specific bloods • Management plan • Referral • Handover Khaled M. Hassan MD; 2011
