CHA2DS2VA and stroke risk table
The table on the Stroke prevention in atrial fibrillation page previously demonstrating the CHA2DS2Vasc score and stroke risk has been updated to demonstrate the CHADS2VA score and stroke risk.
Atrial fibrillation stroke risk
The Stroke prevention in atrial fibrillation page has been updated with a revised segment on AF stroke risk.
Minimum O2 flow rate through a Hudson mask is 5L/min.
The Oxygen therapy page has been updated with expanded details on the minimum O2 flow rate through a Hudson face mask.
Blood gas calculations require PaCO2 or PaO2 values, not venous PCO2 or PO2 values
The Blood gasses page has been updated to better reflect that, if you are going to do calculations on blood gas results at all, you need to use arterial O2, CO2 and HCO3 values. Better still, learn something else that is less prone to error, better validated and more clinically useful…..
PaO2 and PaCO2
All instances of PO2 and PCO2 in the manual have been updated to PaO2 and PaCO2 whenever relevant to prevent readers thinking that PO2 and PCO2 may mean venous PO2 or PCO2.
Ensuring extent of neuromuscular paralysis is measured and reversed prior to extubation
The Endotracheal extubation page has been updated with additional emphasis on ensuring the extent of neuromuscular paralysis is measured and reversed prior to extubation. In particular, do not assume neuromuscular blockade will have worn off after a few hours in ED patients.
Duration of action of rocuronium
The Non depolarising neuromuscular blocking agents page has been updated with additional information about the duration of action of rocuronium, particularly emphasising it is highly variable and may be very significantly prolonged.
Beat to beat variation in QRS amplitude in AF
The Assessment of atrial fibrillation or flutter page has been updated with information about the beat to beat variation in QRS amplitude in AF,
Treatment of AF through an accessory pathway
The Supraventricular tachycardia page has been updated to better reflect the dangers of AV nodal blockade in AF through an accessory pathway.
Features of AFib through an accessory pathway
The Supraventricular tachycardia page has been updated with additional information about the features of AF through an accessory pathway.
Important correction : AFib and accessory pathway – ventricular rate often > 200bpm
The Supraventricular tachycardia page has had a significant correction. Previously it was stated that in AFib with an accessory pathway the ventricular rate was often < 200bpm, when it is actually commonly > 200bpm.
Activated charcoal
The Activated charcoal page has been revised and updated, including some changes to the indications and contra-indications.
Substance related seizures
The Substance induced seizures page has been revised and updated.
Drug related seizures page name change to Substance induced seizures
The page previously known as Drug related seizures has been changed to Substance induced seizures.
Pacemaker lead positions
The Permanent transvenous pacemakers page has been updated with additional information about lead positions.
His bundle pacing diagram
The Permanent transvenous pacemakers page has been updated with a diagram of a typical 2 lead His bundle pacemaker configuration.
3 lead pacemaker position diagram
The Permanent transvenous pacemakers page has been updated with a diagram of a typical 3 lead pacemaker configuration.
Body temperature and sepsis
Additional information about body temperature in sepsis has been added to the Assessment of sepsis page.
Adult sepsis pathway
Information about the Adult sepsis pathway has been added to the Assessment of sepsis page.
Management of sepsis
The Management of sepsis page has had a number of other small updates and improvements.
