Objective To compare the effi cacy of oral sweet solutions to water or no treatment in infants aged 1-12 months during immunisation. Methods Randomised controlled trials (RCTs) were retrieved through internet searches or manual searches of reference lists. Search terms included newborn, infant, pain, sucrose and alternative names for sweet solutions. Summary estimates with 95% CIs were calculated and included relative risk (RR), risk difference (RD) and number needed to treat to benefi t (NNTB) for dichotomous outcomes, and weighted mean differences (WMD) for continuous outcomes. Where pooling of results was not possible, a narrative summary of study results is presented. Results Of the 695 studies identifi ed, 14 RCTs with 1674 injections met the inclusion criteria. Sucrose or glucose, compared to water or no treatment decreased crying during or following immunisation in 13 of the 14 studies. Infants receiving 30% glucose (three trials, 243 infants) had a decreased RR in crying incidence following immunisation (typical RR 0.80, 95% CI 0.69 to 0.93; RD −0.17, 95% CI −0.29 to −0.05; NNTB 6, 95% CI 3 to 20). With sucrose or glucose, there was a 10% WMD reduction in proportion of crying time (95% CI −18 to −2) and a 12 s reduction in crying duration (95% CI −23 to −0.7 s). An optimal dose of sucrose or glucose could not be ascertained due to the varied volumes and concentrations used. Conclusion Infants aged 1-12 months administered sucrose or glucose before immunisation had moderately reduced incidence and duration of crying. Healthcare professionals should consider using sucrose or glucose before and during immunisation.
BACKGROUNDExtensive research shows that oral sucrose, glucose and other sweet tasting solutions are effective analgesics during minor painful procedures in neonates. 1 2 The administration of sweet solutions (in particular sucrose and glucose) is now widely recommended for routine use prior to painful procedures in newborn infants. [3][4][5][6][7] Although the analgesic effect of sucrose and glucose on newborns is well established, little is known about whether these solutions or other sweet tasting solutions are effective in reducing procedural pain in infants beyond the newborn period. This gap in knowledge was the subject of a recent narrative literature review of 10 published randomised controlled trials (RCTs) in which confl icting results across studies were highlighted. 8 A systematic review and meta-analyses were recommended to ascertain whether current evidence supports the use of sweet solutions for pain management beyond the neonatal period. Therefore, the aim of our study was to conduct a systematic review and metaanalyses on the effectiveness of sweet solutions during painful procedures for infants beyond the neonatal period up to 12 months of age.
