Cardio pulmonary resuscitation

  1. 1. Cardiopulmonary resuscitation Dr.V.Ravimohan What I learned in the ILS training http://www.mrcogexam.net
  2. 2. Chain of survival <ul><li>Early recognition and call for help </li></ul><ul><li>Early cardiopulmonary resuscitation (CPR) </li></ul><ul><li>Early defibrillation </li></ul><ul><li>Post resuscitation care </li></ul>
  3. 3. Early recognition <ul><li>Most in-hospital cardiac arrests are not sudden or unpredictable events </li></ul><ul><li>Hypoxia or hypotension are either not noticed by staff ,or are recognised but treated poorly. </li></ul><ul><li>2 systems </li></ul><ul><li>early warning scores </li></ul><ul><li> calling criteria </li></ul><ul><li>“ cardiac arrest team” “Medical emergency team” </li></ul>
  4. 4. Medical emergency team calling criteria Acute change in Physiology Airway Threatened Breathing All respiratory arrests Respiratory rate < 5/ min Respiratory rate >36/min Circulation All cardiac arrests Pulse rate <40/min Pulse rate > 140/min Systolic pressure <90 mmHg Neurology Sudden decrease in level of consciousness Decrease in GCS of > 2 points Repeated or prolonged seizures Other Any patient causing concern who doesn’t fit the above criteria

  19. 19. Advanced life support cardiac rhythm <ul><li>2 groups of cardiac rhythm </li></ul><ul><ul><li>Shock able rhythm </li></ul></ul><ul><ul><ul><li>Ventricular fibrillation </li></ul></ul></ul><ul><ul><ul><li>Pulse less ventricular tachycardia </li></ul></ul></ul><ul><ul><li>Non shock able rhythm </li></ul></ul><ul><ul><ul><li>Asytole </li></ul></ul></ul><ul><ul><ul><li>Pulse less electrical activity </li></ul></ul></ul>
  20. 20. Shock able Rhythm
  21. 21. 3 possibilities
  22. 22. VT/VF persists
  23. 23. VF/VT still persists
  24. 26. Some tips <ul><li>Lidocaine 100mg IV is an alternative for amidarone but isn’t an option if amidarone is already given </li></ul><ul><li>If there is doubt about whether a rhythm is Asystole or very fine AF </li></ul><ul><ul><ul><li>don’t defibrillate </li></ul></ul></ul><ul><ul><ul><li>Very fine VF is unlikely to respond to shock </li></ul></ul></ul>
  25. 27. Precordial Thump <ul><li>May be useful in VF/VT cardiac arrest which was witnessed and monitored sudden collapse </li></ul><ul><li>Ulnar edge of a tightly clenched fist </li></ul><ul><li>From height of about 20 cm </li></ul><ul><li>Thumb is most likely to be successful in converting VT to sinus rhythm </li></ul>
  26. 28. PULSELESS ELECTRICAL ACTIVITY <ul><li>Definition: organised electrical activity in the absence of any palpable pulses. </li></ul>
  27. 29. Treatment for PEA
  28. 31. If VT/VF persists <ul><li>Follow shock able side of algorithm </li></ul>
  29. 33. Treatment for asystole and slow PEA(rate <60 min -1 )
  30. 34. During CPR
  31. 35. Reversible causes 4H 4T Hypoxia Tension pneumothorax Hypovolaemia Tamponade,cardiac Hypo/Hyperkalaemia/metabolic Toxins Hypothermia Thrombosis
  32. 36. 4 H Hypoxia 100% oxygen Ensure adequate chest rise & bilateral breath sounds Hypovolaemia Crystalloid/Colloid Surgery Hyperkalaemia 12 ECG may help in the diagnosis Check for hypoglycaemia Hypothermia
  33. 37. 4T Tension pneumothorax May be a complication of inserting central venous catheter Signs: decreased air entry decreased expansion hyperresonance percussion on affected side Do: needle thoracocentesis Tamponade cardiac Cardiac arrest after penetrating chest trauma 2 reasons:A.hypovolaemia B.cardiac tamponade Do: needle pericardiocentesis or resuscitative thoracotomy Toxins Thrombosis Consider thrombolytic therapy
  34. 38. CPR in a pregnant patient <ul><li>Left lateral tilt(15-30 degrees) of patient </li></ul><ul><li>Periarrest caesarean section should begin within 4 minutes </li></ul><ul><li>Sterile preparation is not necessary </li></ul><ul><li>Moving the patient to operating theatre isn’t necessary </li></ul>
