Trial design and protocol of randomized controlled trial comparing the efficacy of oral mefenamic acid, paracetamol and placebo for analgesic prophylaxis in childhood vaccination (MAP VaC trial)
Abstract
Background: Needle related pain has been one of the most important concerns for parents of children receiving vaccination. Non-steroidal anti-inflammatory drugs (NSAIDs) like paracetamol and mefenamic acid have been commonly used as analgesics in pediatric population. However, prophylactic administration of these drugs for analgesia during vaccination has not been studied. The main objective of this study is to compare the efficacy of prophylactic paracetamol, mefenamic acid and placebo on needle pain associated with vaccination.Methods: This is a three-arm parallel, triple blind, randomized controlled trial. Children aged 6 weeks to 7 years who need immunization as per national immunization schedule and reporting to pediatric outpatient department (OPD) at tertiary level hospital, AIIMS Mangalagiri, Andhra Pradesh, will be included. All participants will be randomly allotted to any of the three groups by computer based block randomization. Each participant will be given any one of the three drugs as per their allocation. Vaccination will be done as per national immunization schedule after 30 minutes of drug administration. Face, legs, activity, cry, consolability (FLACC) scoring will be done immediately after vaccine administration and repeated at 15 minutes and 30 minutes. All personnel involved in randomization, drug and vaccine administration, FLACC scoring and statistical analysis will be blinded along with parents and children enrolled in the study.Conclusions: If this…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
