Effects of rectally administered paracetamol on infants delivered by vacuum extraction.
OBJECTIVE
To evaluate whether paracetamol (20 mg/kg rectally) relieves pain in infants delivered by vacuum extraction, and improves clinical condition.


METHODS
Prospective, randomised, double-blind, placebo-controlled study. Infants delivered by vacuum extraction were randomised either to the study group (n=61) and given paracetamol or to the control group (n=61) receiving placebo. Pain assessment was performed by a validated pain score and by scoring the clinical condition. Both scores and clinical symptoms in these groups were compared with symptoms in a reference group (n=66) with uncomplicated pregnancy and delivery in vertex position without vacuum extraction.


RESULTS
Pain score did not differ between groups; clinical condition in the study group improved only after the first dose. There was a significant difference (P<0.05) in objective clinical symptoms in the vacuum extraction groups, compared to the reference group.


CONCLUSIONS
One dose of paracetamol given to neonates delivered by vacuum extraction significantly improved their clinical condition, but did not result in a significant change in objective pain scores. Subsequent doses of paracetamol did not show any effect on the clinical symptoms or appearance of the neonates studied.
