Abstract

OBJECTIVES To evaluate the effect of sucrose solution given by mouth on infant crying times and measures of distress in the immunisation clinic.

DESIGN Randomised, double blind, placebo controlled trial of sucrose solution 75% wt/vol v sterile water as a control.

SETTING The immunisation clinic of the Women’s and Children’s Hospital, Adelaide.

PATIENTS A total of 107 healthy infants attending for 2, 4, or 6 month immunisations with polio by mouth (Sabin), intramuscular diphtheria, tetanus, and pertussis (DTP), and intramuscular Haemophilus influenzae type b were randomised to receive 2 ml 75% sucrose solution or sterile water by mouth before the two injections.

METHODS The duration of infant crying was recorded during and immediately after two intramuscular immunisations and infant distress was assessed by a visual analogue scale (Oucher scores) independently by a nurse and a parent.

RESULTS The administration of 2 ml 75% sucrose solution by mouth reduced the infant crying time and Oucher distress scores after immunisation with DTP/H influenzae type b.

CONCLUSIONS Infant immunisation by intramuscular injection is a distressing procedure for infants and parents. Sucrose solution at a high concentration reduces infant distress and is safe and clinically useful in this setting.
