Effects of different types and concentration of oral sweet solution on reducing neonatal pain during heel lance procedures / 中华儿科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To compare the effect of different types and concentrations of sweet solutions on neonatal pain during heel lance procedure.</p><p><b>METHOD</b>Totally 560 full term neonates (male 295, female 265) were randomized into 7 groupsplacebo group (plain water), 10% glucose, 25% glucose, 50% glucose, 12% sucrose, 24% sucrose and 30% sucrose groups.In each group, 2 ml corresponding oral solutions were administered through a syringe by dripping into the neonate's mouth 2 minute before heel lance. The procedure process was recorded by videos, from which to collect heart rate, oxygen saturation and pain score 1 min before puncture, 3, 5 and 10 min after puncture.</p><p><b>RESULT</b>The average heart rate increase 3, 5 and 10 min after procedure in the 25% and 50% glucose groups, 12% and 24% and 30% sucrose groups was significantly lower than those in the placebo group (P < 0.01 or 0.05). The average heart rate increase 3 min after procedure in the sucrose group was lower than that in the glucose group (P < 0.01).Neonates who received 30% sucrose has a significantly lower average heart rate increase than those who received 12% and 24% sucrose 3 min after heel lance (both P < 0.05) . The average oxygen saturation decrease 3, 5, 10 min after procedure was significantly lower than those in the placebo group (P < 0.01). The average oxygen saturation decrease 3 min after procedure in the sucrose groups was significantly lower than that in the glucose groups (P < 0.01). The average pain score 3, 5, 10 min after procedure was significantly lower than those in the placebo group (P < 0.01). The average pain score 3 min after procedure in the sucrose groups was significantly lower than that in the glucose groups (P < 0.01).</p><p><b>CONCLUSION</b>Oral administration of sweet solutions is an effective way to relieve neonatal pain on procedure, and sucrose has a better pain relief action than glucose, moreover, 30% sucrose provides better effect in control of heart rate increase 3 min after heel lance, but the best concentration of sucrose for pain relief needs further study.</p>
