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. Please note that none of the values used in the manual have changed, just the units used have been corrected. Thanks to an astute subscriber for noting these errors.

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 stating it was of hyperkalaemia.

U waves are often mistaken as T waves.

A low dibucaine number, not a high one, is a measure of increased suxamethonium sensitivity. The Suxamethonium page in the Resuscitation section has been corrected to reflect this

The trochlear (IV) and abducens (VI) nerves have now been correctly numbered in the Assessment of vision page in the Neurological disorders section. Previously their Roman numbering had been reversed.

The dose of naloxone as described in the Neonatal Resuscitation page ( p146 of text) in the Resuscitation section should be 0.1 microgram/kg not 0.1mg/kg as stated. The 0.1microgram/kg dose can be repeated if required.
