Analgesia no farmacológica en la vacunación. Valoración de pediatras, pacientes y tutores

Abstract

Introduction The use of nonpharmacological measures to reduce pain during vaccination has been studied extensively in infants, but there are fewer studies on its effectiveness in older children and on the parental perception of pain in children. Methods We conducted a multicentre, quasi-experimental interventional study with a control group. Patients: Infants aged 2 and 11 months and children aged 4 years that attended routine vaccination appointments. Setting: Primary care. Intervention during vaccination: infants were breastfed and 4-year-old children blew a party horn. Control: vaccination performed following routine practice. Measurement: NIPS (Neonatal Infant Pain Scale) and duration of crying in infants, Wong−Baker FACES pain rating scale in older children and parents. Results The study included 125 children (intervention: 60; control: 65). There was a significant decrease in perceived pain in the intervention groups: NIPS score in infants, 3.8 ± 1.1 compared to 5.2 ± 0.7 (P < .001); Wong−Baker FACES score at 4 years of 3.3 ± 1.7 compared to 4.2 ± 1.6 (P = .042). These same differences in support of the intervention were reflected in the parental assessments (3.4 ± 1.3 vs 4.5 ± 1.5; P < .001). The correlation between child and parent scores was strongly positive: 0.7 (95% CI, 0.59–0.78). However, the duration of crying was longer in the intervention group. Conclusions The use of distraction techniques reduces pain in children and the pain perceived by parents in their children, thus increasing their satisfaction with the procedure.
