Dear All, 

I wanted to know your unit’s antibiotic choice in 22-23 week babies. We use Benzyl Penicillin and Gentamicin. Dose of Gentamicin is 5 mg/kg/dose @ 36 hourly interval. However we’ve seen actuate kidney injuries with this dosage and we’re wondering whether to change to cefotaxime instead. Would be grateful for your input.

@RyoItoshima would you like to tell us about your practice from Japan?

Penicillin and amikacyn

 

We would also probably go with bensyl-Pc and Amikacin, the latter dosed every 48 hours (and with checking serum-konc of amikacin before the 2nd dose)

Empirical treatment of the first choice is Ampicilin/Gentamcin

Cefotaxime first line for EOS in Southampton. 

We give Ampicillin / Gentamicin. Dose of Gentamicin is 5mg/kg first dose, then 36h later 3.5mg/kg @24h intervals. Step up from Ampicillin if there is evidence of other bacteria (resistant?) from mother

Ampicillin/Gentamicin

Gentamicin 5 mg/kg every 48h hours according to the dosage handbook of the American pharmacists association 

Ampicillin plus gentamicin in our NICU, according Neofax dosages. We stop antibiotics if blood culture is negative (48-72 hours) and no clinical or laboratory signs of active infection.

Hi Vicky

Do you use Cefotaxime monotherapy?

Yes- we would add in amoxicillin if concerns re: listeria. 

No aminoglycoside....

kindly review your Gentamicin dosage in this clinical context can you please high light acute kidney injury is it dose related Acute tubular necrosis? 
please update thank you

Hi Vicky

That's interesting as it will save doing drug levels and medications errors as well.

My questions

- how long since you intoduced this  as 1st line for EOS

- what's the microbiology advice regarding resisitance as you know most of other units use cefotaxime and vanc as 3rd line Abx.

- What's your second and third line Abx policy .

Thanks again

Gentamycin / Ampicillin. Intervall and Dose acorrding to Neofax. Through Level measuring before second Dose (who determine also peak level?). No 3. Generation Cephalosporines because reported higher appearence of ESBL bacteria. 

I can’t tell you how long we’ve used cefotaxime for- but definitely 10 years.
 

You are best speaking to a colleague of mine for more details- if you want to message me your email address I can pass it on?  Microbiology data monitored and I assume no concerns with ESBLs!

second line fluclox and gent or vanc and gent if a central line present. 

We use amp and gent. With gent doses of 4mg q 48 hours.

We haven't experienced any kidney failure.
