Adenosine dose for paediatric SVT

The paediatric dose for SVT has been changed on the Supraventricular tachycardia and Paediatric cardiac arrest pages to be consistent with current ARC guidelines and the Paediatric resuscitation chart in the manual. The adenosine doses recommended are now: initial dose 0.1 mg/kg, repeat dose 0.2 mg/kg, maximum dose 0.3 mg/kg (or 12mg)

Enoxaparin dose for DVT

On the Deep venous thrombosis page under Management, the doses of heparin (5000Units bd) and enoxaparin (40mg/day) previously quoted on this page are for prophylaxis, and not treatment of DVT.

Austin Flint murmur

The description of the Austin Flint murmur as that of MR on the Aortic valve disease page has been corrected.

ECG intervals correction

The Normal ECG morphology page has been updated with an image that now demonstrates the correct ECG intervals. The previous image demonstrated inaccuracies in the start and finish of the PR, QRS, ST and QT intervals. More explicit descriptions of the relevant intervals have been added to The Normal ECG page as well.

Beta-HCG units correction

The correct measurement units (mIU/mL) have been applied to the various pages where quantitative beta HCG levels have been used.Previously many of the values were quoted in IU/mL, or just IU.

Hypokalaemia corrections

Please be aware that on page 271 of the print version, and the old Hypokalaemia page (now corrected) (Link) had a few annoying little errors. ECG changes of hypokalaemia occur when the K+ is < 2.7mmo/L, not when it is >2.7mmol/L. The ECG image was of hypokalaemia (as in the title) despite the text beneath … Read more

Dibucaine number
