Alprostadil

To maintain or restore patency of the ductus arteriosus

Only to be used in infants who are ventilated or where ventilation is immediately available

DO NOT DELAY IN STARTING Alprostadil if: there is clinical
suspicion of duct dependent CHD while waiting for paediatric cardiology opinion OR echocardiogram, even when in-house echo facilities are present.

Quick-Wee method

Have you ever wanted an infant to PU faster?

Gentle suprapubic cutaneous stimulation with gauze soaked in cold fluid (the Quick-Wee method) led to a clinically and statistically significant increase in voiding and successful urine collection within five minutes for infants aged 1-12 months

An ideal job to be given to parents/carers

Anion Gap & Metabolic Acidosis

The anion gap (AG) represents the amount of unmeasured anions in the plasma.

AG =([Na]+[K]) – ([HCO3]+[Cl])

The main contributor to the AG is albumin (decreasing albumin by 1g/l reduces the AG by 0.25) so hypoalbuminaemia can falsely reduce the AG.

Corrected AG = AG + (0.25*(40-[albumin]))

(However, this relies on getting LFT’s back about 1 hour) Read more

A-a gradient

A-a gradient = Alveolar Oxygen – arterial Oxygen

This is “relatively” simple way of working out if the paO2 on a ABG is normal, and demonstrates V/Q mismatch well. V/Q mismatch is simple terms is either an area of the lung either under ventilated(pneumonia) or under perfused (PE). Read more
