Profoundly sick patient, call for help, don't panic instead focus on ABCs and you can work it out

Introduction

• Work quickly and logically. POCUS may be useful.
• Start O₂ and get IV access and start Observations.
• Find a central pulse and monitor it. Always think ABC.
• Check airway is fine, check breathing and circulation.
• Get early IV access, Decompress tension PTX if likely.
• Significant haemorrhage: Give blood if bleeding out.
• Comatose assess need for ABC and Intubation
• Consider urinary catheter if shocked to monitor output.
• Antibiotics Co-Amoxiclav 1.2 g IV 6-8 hourly +/- Gentamicin or local guidance if not pen allergic
• High yield tests if well enough: Coma CT Scan. Breathless ECG, CXR, Bedside Echocardiogram, Chest pain: ECG, CXR, CT Aorta. Dimer. Lactate, ABG. Abdominal pain: Erect CXR, CT abdomen

Always keep asking if patient not improving

• Is the diagnosis correct?
• Is the diagnosis complete?
• Could there be more than one diagnosis?
• What information do I need -is that test available
• Shall I phone a friend - my registrar/consultant

Airway

Breathlessness

• Mechanical Airways Issue: fast bleep anaesthetics/ENT if stridor and suspected epiglottitis do not examine airway. Give oxygen.
• Otherwise Head tilt, chin lift and inspect mouth. Remove any obstruction.
• Hypoventilating: Give naloxone 0.4 mg (400mcg) repeated as needed. Can give up to 2 mg initially and max 10 mg. High flow oxygen, oropharyngeal airway, Ambu bag. Anaesthetic help. RSI. Other causes could be neurological? Myasthenia, GBS, MND
• Tension Pneumothorax. Pushes lungs away. Resonant. Decreased air entry. Context e.g. ventilated or trauma. Then decompress with needle 2nd space and mid-clavicular line
• Acute LVF: Crackles, Sitting up, Tachypnoeic. Give GTN and IV Frusemide and get ECG and CXR. If STEMI fast track for reperfusion.
• Acute PE: Type 1 RF. Chest pain. Tachypnoeic. ECG tachycardia. If Hypotensive consider Bedside Echo if available and/or CTPA. Consider IV heparin. Consider thrombolysis if haemodynamic compromised
• Acute Severe Asthma: Tiring patient. Begins to CO₂ retain and become hypoxia. Get ITU to see. See section
• Exacerbation of COPD: Known COPD. Wheeze, tachypnoeic. Prolonged expiratory phase. 24-28% oxygen. Consider NIV
• Pneumonia/COVID19: CXR changes, hypoxia
• Hyperventilating: Panic attack. Low PCO₂. Diagnose when all else excluded

Decompressing Tension Pneumothorax

Hypotensive

• If no clear cause consider a trial of 500 ml of N-Saline and reassess. If breathless then trial 250 ml unless clearly in pulmonary oedema.
• Haemorrhagic shock: GI bleed, liver disease, varices
• Septic Shock: Infection. Lactate high Start Sepsis 6 with broad-spectrum IV antibiotics
• Leaking AAA: abdominal pain. Palpable aneurysms. IV access. Vascular consult
• Ectopic pregnancy: Fertile female shock and abdominal pain
• Cardiogenic shock: Recent Chest pain but can be silent, Get ECG STEMI, New murmur. Telemetry, Echocardiogram
• Dissection Aortic Aneurysm: chest pain needs CT aorta, BP control and cardiothoracic
• Anaphylaxis: bee sting, drug, penicillin. Urticaria, wheeze, rash. Needs IM Adrenaline and 1L N-Saline over 30 mins
• Cardiac tamponade High JVP, Muffled heart sounds, trauma, anticoagulated, BP fall with inspiration and cannot be palpated (pulsus paradoxus)
• Pulmonary embolism: tachypnoeic. High JVP, Loud P2, DVT, Risk factors, ECG changes. CXR may be normal
• Meningococcal septicaemia: non-blanching rash, fever, malaise, obtunded, meningism
• Addison disease: Pigmentation

Treating Anaphylaxis: See topic

Chest Pain

• Acute coronary syndrome: get CXR. Treat ACS
• Acute Aortic dissection: Get CXR, CT Aortogram/TOE. Avoid antithrombotics until excluded
• Acute Pulmonary Embolism: CTPA
• Oesophageal disease: rupture, inflammation, GORD

Comatose

• Hypoglycaemia: Give Glucose
• Opiates: Give naloxone 0.4 mg (400mcg) repeated as needed. Can give up to 2 mg initially and max 10 mg
• Space Occupying lesion: get CT head
• Alcohol intoxication or other drugs
• Meningitis/Encephalitis: Treat Aciclovir/Ceftriaxone and consider LP
• Massive stroke (ischaemic, haemorrhagic or SAH) or bilateral thalamic infarct
• Post seizure or Non convulsive status
• Cerebral malaria: foreign travel

Arrhythmias

• If rate < 50 or > 120 then ask If the rhythm could be the case.
• See algorithm for bradycardia and tachycardia. Get ECG
• Tachycardia causing hypotension: DC cardioversion
• Bradycardia causing hypotension: Atropine, External or Transvenous Pacing wire

Abdominal Pain

• Leaking AAA: abdominal pain and hypotension. IV access. Vascular surgeons
• Acute Pancreatitis: peritonism, bruising flanks
• Perforated viscus: CXR and CT abdomen to establish cause. NBM. IV fluids, Broad spectrum antibiotics
• Ectopic pregnancy: fertile female. Abdominal pain and collapse
• GI bleed: Needs endoscopy, PPI and vasopressin if varices suspected. Correct coagulopathy. Transfuse as needed
