Context Heel prick is one among the common painful procedures in neonates. We performed a systematic review and network metaanalysis (NMA) to compare the efficacy of different interventions for analgesia during heel prick in neonates. Evidence acquisition Medline, Cochrane, Embase and CINAHL databases were searched from inception until February 2023. Randomized and quasi-randomized trials that evaluated different pharmacological and non-pharmacological interventions for analgesia during heel prick for neonates were included. Data from the included trials were extracted in duplicate. A NMA with a frequentist random-effects model was used for data synthesis. Certainty of evidence (CoE) was assessed using GRADE. We adhered to the PRISMA-NMA guidelines. Results One-hundred-and-three trials comparing 51 different analgesic measures were included. Among the 38 interventions, for pain “during” heel prick, non-nutritive suckling (NNS) plus sucrose [SMD Ȓ3.15 (Ȓ2.62, Ȓ3.69)], followed by breastfeeding, glucose, expressed breast milk (EBM), sucrose, NNS and touch massage, had a high certainty of evidence (CoE) to reduce pain scores when compared to no intervention. Among the 23 interventions for pain at 30 seconds after heel-prick, moderate CoE was noted for facilitated tucking plus NNS plus music, glucose, NNS plus sucrose, sucrose plus swaddling, mother holding, EBM, sucrose and NNS. Conclusions Oral sucrose 2 minutes before combined with NNS during the procedure, was the best intervention for reducing pain during heel prick. It also effectively reduced pain scores 30 seconds and 1 minute after the procedure. Other interventions with moderate to high CoE for a significant reduction in pain during and at 30 seconds after heel prick are oral sucrose, oral glucose, EBM and NNS. All these are low-cost and feasible interventions for most of the settings.
