This article aims to review the main studies evaluating glucose as a therapeutic alternative during mildly to moderately painful procedures in neonatology, highlighting its benefits and limitations. During their stay in neonatal intensive care units, neonates are constantly subjected to a number of painful procedures without proper therapeutic management, although the medical literature emphatically recommends this type of management, highlighting the deleterious neurological consequences of pain. Most of these interventions are frequently necessary in neonatal intensive care units to maintain clinical stability in these children; the use of systemic analgesia, however, is not considered to be a good option. The administration of oral glucose solution is apparently effective and safe for pain control during procedures causing mild-to-moderate pain in neonate intensive care units, with rare adverse effects; however, its mode of action has not yet been described clearly in the literature. The administration of oral glucose solution is well described for use in venous punctures; it is apparently effective also for heel punctures, especially when associated with nonnutritive sucking, with most studies showing favorable results.
