  4. Asystole

    Absence of electrical and mechanical activity in the heart - a non-shockable cardiac arrest. Algorithm
  5. Atrial Fibrillation

    An arryhthmia: Rapid and asynchronous contractions of the atrium, causing irregular contraction of the ventricles. The pulse will be irregular in rate and strength, and the wrist and Apex pulse rates will be asymmetrical.  AF details
  6. Barotrauma

    Injury due to excess pressure in tissues.
  7. Beta (β) blockers

    Negative inotropic drugs which block the affect of Adrenaline on the heart and blood vessels, by weakening effects of the Sympathetic Nervous System on heart conductivity, and reducing blood pressure and heart rate.  Example

  9. Bronchospasm

    Sudden difficulty in breathing caused by constriction of plain muscle in the walls of the bronchi. Spontaneously breathing patients may have an audible wheeze.  Actions   ||   During anaesthesia
  10. Can't intubate, can't ventilate

    When intubation fails, and the patient suffers hypoxaemia and difficult ventilation, a rescue algorithm must be followed, as described by the  Difficult Airway Society
  11. Cardiac arrest

    The heart stops pumping blood around the body, resulting in unconsciousness and abnormal breathing, which requires immediate cardiopulmonary resuscitation. 
    User manual ||  Youtube ||  Dealing with an arrest
  12. Cardiac (pericardial) tamponade

    A condition in which gas or fluid, such as blood or pus, accumulates in the pericardium faster than the pericardial sac can stretch. If the fluid/gas significantly elevates the pressure on the heart, it will prevent the heart's ventricles from filling properly, leading to a low stroke volume, shock, and death.  Actions

    Increased level of carbon dioxide in the blood.
  29. Hyperkalaemia

    A high level of serum potassium: the normal range is 3.5 – 5.3 mmol/L.
    For raised levels, give 10ml of calcium gluconate 10% intravenously over 2-5 minutes; then 10 IU Actrapid + Glucose 50%, 50 mls.

    ECG characteristics of hyperkalemia:
    • P-waves are widened and low amplitude due to slowed conduction.
    • Tall tented T waves.
    • QRS widening
    • Fusion of QRS-T
    • Loss of the ST segment
  30. Hypertension

    Blood pressure which is above the normal range for a particular category of person, according to such factors as age and weight. Typical treatment is by a Beta-blocker, such as Atenolol, Esmolol, or Labetalol.
  31. Hyperventilation (hyperpnoea)

    • ST depression
  33. Hypotension

    Blood pressure which is below the normal range for a particular category of person, according to such factors as age and weight. Typically treated by a vasoconstrictor. Low diastolic pressure suggests arterial vasodilation, as with sepsis or anaphylaxis. A small pulse pressure could be due to arterial vasoconstriction, such as with hypovolaemia, or cardiogenic shock

    • Mataraminol
    • Ephedrine
    • Noradrenaline
    • Phenylepharine

  34. Hypothermia

    Core body temperature below (35°C). Consequences can vary from minor to severe.  Mitigations
  35. Hypoventilation (hypopnoea)

    Hypoventilation refers to inadequate breathing and impaired gas exchange, which prevents the body from being able to remove carbon dioxide appropriately. As a consequence, there develops an increase in the level of carbon dioxide (hypercapnia) in the blood, together with a decreased level of oxygen.  Significance
  36. Hypovolaemia

    Reduced circulating blood volume, typically caused by shock.
    • Dry mouth
    • Dry axillary skin
    • Thirst
    • Postural hypotension

    The immediate goal is to raise systolic blood pressure to 100 mmHg, by administering 250-1,000 ml isotonic (0.9%) saline solution.
  37. Hypoxia

    Low level of oxygen in the tissues (cellular level).  Anaesthetic significance
  38. Hypoxaemia

    Low level of oxygen in arterial blood.
  39. Laryngospasm

  44. Opioid overdose

    Causes respiratory depression, signified by a low minute volume, with resultant hypercapnia.

    • Pin-point pupils
    • Slow respiratory rate
    • Sighing
    • Hypercapnia, then hypoxia

    Reverse with Naloxone, or stimulate respiration with eg, Doxapram.
  45. Oxygen toxicity

    A condition resulting from the harmful effects of breathing molecular oxygen at elevated partial pressures (hyperoxia). Severe cases can result in cell damage and death, with effects most often seen in the central nervous system, lungs and eyes. Oxygen toxicity is a concern for those on high concentrations of oxygen (particularly premature babies), and those undergoing hyperbaric oxygen therapy. Symptoms may include disorientation, breathing problems, burning sensation with deep breathing, anxiety, vomiting, and vision changes.

  55. Post operative nausea and vomiting

    A side effect of general anaesthesia, suffered by 1 in 4 patients. If unmanaged, can lead to pulmonary aspiration of gastric contents. Younger patients are more susceptible than older ones, as are gynaecological, urological, strabismus correction, and middle ear surgery patients. Treatment is by  antiemetics, dispensing a combination of agents, until efficacy is achieved.  Drugs and actions

  57. Precordial thump

    An attempt to interrupt an arrhythmia, such as Ventricular Fibrillation or pulseless Ventricular Tachycardia, by making a single strike, with the fist, to the centre of the patient's sternum. The thump is only effective if made at the onset of a witnessed and monitored adverse rhythm (VF/pVT), and a defibrillator is not immediately available. Latest resuscitation guidelines de-emphasise use of the precordial thump.

  59. Primary survey

    Steps to take when assessing an unconscious patient.

    Order of steps
    DangerAssess Dangers to yourself and casualties
    ResponseUse the Glasgow Coma Scale to ascertain the level of consciousness
    AirwayExamine the Airway for obstructions
    BreathingLook, listen, and feel for adequate respiratory effort. Supplement with oxygen to correct hypoxia, if saturations are below 95%
    CirculationIf a carotid pulse is not palpable, then resuscitation should be commenced
  60. Pulmonary embolism

    An embolism which usually originates from the proximal veins of the thigh and pelvis.
    Details   ||   Emergency steps
  61. Pulmonary oedema

    Excess of watery fluid in the lungs, which collects in the air sacs, making it difficult to breathe. Pulmonary oedema is most often caused by heart failure (cardiogenic pulmonary oedema), but it may be caused by other conditions, which do not directly affect the heart (non-cardiogenic pulmonary oedema).
  62. Pulseless Electrical Activity (PEA)

    A cardiac arrest where the patient has cardiac electrical activity, which would otherwise produce cardiac output and an obvious pulse. PEA usually has an underlying treatable cause which, in emergency situations, is most often hypovolemia. Performing a pulse check after a rhythm/monitor check will ensure that PEA is identified.  Cardiac issues
  63. QuickTrach Cricothyrotomy kit

    For making an airway opening during a "can't ventilate" emergency. 
  64. Respiratory failure

    When the respiratory system fails in oxygenation and/or carbon dioxide (CO2) elimination.   Actions

    Basic principles  ||  In Hospital resuscitation
  66. Secondary survey

    A more in depth survey of the patient than the primary survey.  Steps to take
  67. Shock

    Failure of the cardiovascular system to deliver adequate blood flow necessary to properly supply oxygen and nutrients to vital organs, particularly to the kidneys and brain. This inadequate tissue perfusion causes an accumulation of lactic acid in the tissues. If untreated, shock can lead to multiple organ failure.  Recognition and treatment
  68. Stridor

    A harsh vibrating sound, during inspiration, caused by tumour, infection, or partial obstruction of the larynx or trachea.

    • Oxygen and positioning the head of the bed 45 - 90 degrees.

    • Nebulized racemic Adrenaline (0.5 to 0.75 ml of 2.25% racemic Adrenaline added to 2.5 to 3 ml of normal saline) in cases where airway oedema may be the cause of the stridor.

    • Dexamethasone (Decadron) 4-8 mg IV q 8 - 12 h in cases where airway oedema may be the cause of the stridor; note that some time (hours) may be needed for dexamethasone to work fully.

    • Inhaled Heliox (70% helium, 30% oxygen); the effect is almost instantaneous. Helium, being a less dense gas than nitrogen, reduces turbulent flow through the airways.

    • Always ensure an open airway.
  69. Suxamethonium apnoea

    Prolonged effect of Suxamethonium, which means a patient may reverse from anaesthesia, but remain paralysed.  Anaesthesia protocol
  70. Syncope

    A brief period of unconsciousness, due to reduced blood flow to the brain.
  71. Tachycardia

    Fast heart rate/pulse.
    Causes include...
    • Anaemia
    • Fever
    • Hypovolaemia
    • Myocarditis
    • Pain
    • Vasodilation
    • Vagolytic drugs, such as Atropine

      Adult treatment algorithm
  72. Tension pneumothorax

    Pneumothorax due to air escaping into the pleural cavity, typically as a consequence of a penetrating injury.   What to do
  73. Thoracocentesis

    Puncturing the Thorax to aspirate pleural fluid or gas.
  74. Tracheotomy

    A procedure to make an airway opening through the second or third tracheal ring, typically because of upper airway obstruction.
    • A lateral cut is made, superior to the sternal notch.
    • The skin is separated and surrounding tissues dissected, exposing the trachea.
    • The 2nd or 3rd tracheal ring is incised, and the tracheostomy tube placed.
    • The tube cuff is then inflated (2-5 ml).
    • The incision is sutured at the side of the tracheostomy tube.
  75. Ventricular Fibrillation (VF)

    Heart rhythm is chaotic - the heart is in a state of electrical chaos. No blood is pumped from the heart, and the patient has no pulse. The ECG trace lacks P-waves, QRS complexes, or T-waves. Action is electrical defibrillation.
    See  Advanced Life Support
  76. Ventricular Tachycardia (VT)

    A regular and fast beating of the ventricles (120 beats/min), which is too fast for them to fill with sufficient blood betweeen beats. Pulseless VT can lead to Ventricular Fibrillation, which is a more serious condition. Action for pulseless VT is electrical defibrillation.
