The effectiveness of glucose in reducing needle-related procedural pain in infants

Efficacy and safety of non-pharmacological interventions for endotracheal suctioning pain in preterm infants: A systematic review

AIM

To review and analyse the evidence on the efficacy and safety of non-pharmacological interventions for preterm infants to relieve endotracheal suctioning (ES) pain.

DESIGN

A systematic review per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

METHODS

Six databases were searched with a retrieval strategy. Parallel and crossover randomized controlled trials reporting non-pharmacological interventions for relieving ES pain in preterm infants were identified from inception to 1 September 2021. The protocol was published in PROSPERO (CRD42021276058).

RESULTS

Ten studies were retrieved, including nine different non-pharmacological interventions. Seven studies reported that non-pharmacological interventions in relieving pain were more effective than conventional care during ES, and three trials reported its safety. Due to the heterogeneity of pain assessment tools, time of assessment and population, only Facilitated tucking had sufficient evidence that it is a safe and effective non-pharmacological intervention.

Insights on Nutrients as Analgesics in Chronic Pain

Many serious inflammatory disorders and nutrient deficiencies induce chronic pain, and anti-inflammatory diets have been applied successfully to modify the inflammatory symptoms causing chronic pain. Numerous scientific data and clinical investigations have demonstrated that long-term inflammation could lead to an inappropriate or exaggerated sensibility to pain. In addition, some Non-steroidal Anti-inflammatory Drugs (NSAID), which directly act on the many enzymes involved in pain and inflammation, including cyclooxygenases, are used to dampen the algesic signal to the central nervous system, reducing the responses of soft C-fibers to pain stimuli. On the other hand, there are a few reports from both health authorities and physicians, reporting that decreased transmission of pain signals can be achieved and improved, depending on the patient's dietary habit. Many nutrients, as well as a suitable level of exercise (resistance training), are the best methods for improving the total mitochondrial capacity in muscle cells, which can lead to a reduction in sensitivity to pain, particularly by lowering the inflammatory signaling to C-fibers. According to the current literature, it could be proposed that chronic pain results from the changed ratio of neuropeptides, hormones, and poor nutritional status, often related to an underlying inflammatory disorder. The current review also evaluates the effective role of nutrition-related interventions on the severity of chronic pain. This review pointed out that nutritional interventions can have a positive effect on pain experience through the indirect inhibitory effect on prostaglandin E2 and attenuation of mitochondrial dysfunction caused by ischemia/reperfusion in skeletal muscle, improving the intracellular antioxidant defense system. These data highlight the need for more nutrition studies where chronic pain is the primary outcome, using accurate interventions. To date, no nutritional recommendation for chronic pain has been officially proposed. Therefore, the goal of this article is to explore pain management and pain modulation, searching for a mode of nutrition efficient in reducing pain.

Healthcare Providers' Knowledge and Current Practice of Pain Assessment and Management: How Much Progress Have We Made?

Context. Despite improvement in pain management and availability of clinical treatment guidelines, patients in Jordan are still suffering from pain. Negative consequences of undertreated pain are being recognized as a reason for further illnesses and poor quality of life. Healthcare providers (HCPs) are responsible for relieving pain of their patients. Objective. To evaluate the knowledge and attitudes of HCPs toward pain management in Jordan. Methods. A 16-item questionnaire with agree or disagree options was given to 662 HCPs in seven hospitals in Jordan who volunteered to participate in the study. Following data collection, the responses were coded and entered into SPSS. Results. There was a statistically significant difference (p < 0.004) in percentage scores between physicians (36%) and pharmacists (36%) versus nurses (24%). The level of knowledge was the best among physicians, followed by pharmacists specifically in the area of cancer pain management. Nurses scored the lowest for knowledge of pain assessment and management among HCPs. However, HCPs overall scores indicated insufficient knowledge specifically in relation to pain assessment and management among children.

The effect of sucrose as pain relief/comfort during immunisation of 15-month-old children in health care centres: a randomised controlled trial

AIMS AND OBJECTIVES

To investigate the effect of 30% sucrose compared with a placebo (water) as pain relief and comfort during immunisation of 15-month-old children in health care centres.

BACKGROUND

Children experience different levels of pain and distress during immunisation. Sweet solutions function as pain relief during immunisation for infants up to one year of age. However, there are few studies of older children.

DESIGN

An experimental design in which the participants (15-month-old infants) were randomly assigned to an intervention group that received a 30% sugar solution or a control group that received a placebo (water).

METHODS

The study was performed at three health care centres in a large Norwegian municipality. The parents of all 15-month-old infants who were recommended for vaccination (for measles, mumps and rubella) between 5 September 2013 and 31 March 2014 were invited to have their infant participate. Duration of crying was the outcome measure.

RESULTS

A total of 114 children were included (59 in the intervention group, 55 in the control group). The intervention group infants' crying was shorter (18 seconds mean) compared with the control group infants (33 seconds mean). The difference in crying duration between the groups was both statistically and clinically significant.

CONCLUSION

This trial revealed that 30% sucrose orally has a calming and pain-relieving effect on 15-month-old infants during immunisation.

RELEVANCE TO CLINICAL PRACTICE

Public health nurses should use a 30% sucrose solution for pain relief during immunisation of 15-month-old infants.

A systematic review and meta-analyses of nonsucrose sweet solutions for pain relief in neonates

BACKGROUND

Sucrose has been demonstrated to provide analgesia for minor painful procedures in infants. However, results of trials investigating other sweet solutions for neonatal pain relief have not yet been synthesized.

OBJECTIVE

To establish the efficacy of nonsucrose sweet-tasting solutions for pain relief during painful procedures in neonates.

METHOD

The present article is a systematic review and meta-analyses of the literature. Standard methods of the Cochrane Neonatal Collaborative Review Group were used. Literature searches were reviewed for randomized controlled trials investigating the use of sweet solutions, except sucrose, for procedural pain management in neonates. Outcomes assessed included validated pain measures and behavioural and physiological indicators.

RESULTS

Thirty-eight studies (3785 neonates) were included, 35 of which investigated glucose. Heel lancing was performed in 21⁄38 studies and venipuncture in 11⁄38 studies. A 3.6-point reduction in Premature Infant Pain Profile scores during heel lances was observed in studies comparing 20% to 30% glucose with no intervention (two studies, 124 neonates; mean difference -3.6 [95% CI -4.6 to -2.6]; P<0.001; I2=54%). A significant reduction in the incidence of cry after venipuncture for infants receiving 25% to 30% glucose versus water or no intervention was observed (three studies, 130 infants; risk difference -0.18 [95% CI -0.31 to -0.05]; P=0.008, number needed to treat = 6 [95% CI 3 to 20]; I2=63%).

CONCLUSIONS

The present systematic review and meta-analyses demonstrate that glucose reduces pain scores and crying during single heel lances and venipunctures. Results indicate that 20% to 30% glucose solutions have analgesic effects and can be recommended as an alternative to sucrose for procedural pain reduction in healthy term and preterm neonates.

Sucrose for procedural pain management in infants

The use of oral sucrose has been the most extensively studied pain intervention in newborn care to date. More than 150 published studies relating to sweet-taste-induced calming and analgesia in human infants have been identified, of which 100 (65%) include sucrose. With only a few exceptions, sucrose, glucose, or other sweet solutions reduced pain responses during commonly performed painful procedures in diverse populations of infants up to 12 months of age. Sucrose has been widely recommended for routine use during painful procedures in newborn and young infants, yet these recommendations have not been translated into consistent use in clinical practice. One reason may be related to important knowledge and research gaps concerning analgesic effects of sucrose. Notably, the mechanism of sweet-taste-induced analgesia is still not precisely understood, which has implications for using research evidence in practice. The aim of this article is to review what is known about the mechanisms of sucrose-induced analgesia; highlight existing evidence, knowledge gaps, and current controversies; and provide directions for future research and practice.
