Brief Summary:
Purpose. It has been demonstrated clearly that sucrose solutions given before a minor painful procedure can reduce pain among newborns. But, there are no entirely accepted conclusions about the time scheduling of sucrose administration prior to heel lance. In a few studies, various time intervals between sucrose intake and heel lance procedure have been proposed. The aim of this study was to obtain a deeper knowledge of the underlying mechanism by investigating whether a different initiation of heel lance in terms of timing would reduce the effect of orally administered sucrose at heel lance among preterm newborns.
Methods. A randomized, double-blind trial with a validated, neonatal, pain-scoring scale in Gulhane Medical School Hospital in Ankara, Turkey between March 2019 and January 2021. The trial included 69 preterm newborns undergoing heel lance, who were assigned randomly to 1 of 2 groups, ie, group I, with the 2-minute-time interval of per oral 24% sucrose given prior to heel lance or group II, without a time interval of per oral sucrose given prior to heel lance. Pain-related behavior during blood sampling was measured with the Premature Infants Pain Profile-Revised (PIPP-R). Crying incidence, duration, and heart rate were also recorded. The aim of this study was to help to clarify the mechanism underlying the pain-reducing effect of orally administered sucrose by attempting to determine whether elimination of the time interval prior to heel lance would reduce the effect of oral sucrose among preterm newborns. Investigators hypothesized that there would be a significant difference in pain intensity without a waiting period after sucrose ingestion, measured at 30 and 60 s following heel lance using PIPP-R, and adverse events would be higher.
Detailed Description:
The sample size was calculated based on the difference in the PIPP scores of the groups. A sample size of 54 (27 for each group) achieves 80% power to detect a large effect size of 0.8 using a two-sided Mann-Whitney U test with a significance level of 0.05.
After inclusion in the study, participating infants were randomized to one of two possible interventions during a clinically-required heel lance: 1) The 2-minute-time interval of per oral 24% sucrose given prior to heel lance (Group 1) or no time interval of per oral 24% sucrose given prior to heel lance (Group 2) combined with containment in a blanket while in an infant incubator. Enrollment and randomization into the 2-minute-time interval of per oral 24% sucrose given prior to heel lance or no time interval of per oral 24% sucrose given prior to heel lance (within 10 s) interventions were carried out by a member of the research team using a computerized off-site password protected website. Intervention allocation concealment was achieved by using randomly permuted stratified randomization of gestational week and gender. The treatment allocations were inserted into identical sealed envelopes marked only with a number. Solutions of 24% sucrose were freshly prepared daily by pharmacy using 2.4 g sucrose plus 10 ml distilled water. Solutions were packaged in 1 ml sterile syringes and further packaged in opaque sealed envelopes labeled according to the randomization code. The research team including two clinicians and nurses were masked in the treatment allocation. Outcome assessor was also blinded.
