Soothing the Newborn
There are several techniques that have been shown to provide pain relief for newborns (0–28 days of age) undergoing painful procedures. In breastfed newborns, breastfeeding itself is the preferred method to alleviate procedural pain. In addition to being safe, effective, natural, and without added cost, it provides an additional opportunity to promote and support breastfeeding. The individual components of breastfeeding (sucking, sweet taste, and warm contact) may be used separately or, preferably, in combinations when breastfeeding itself is not possible.
Breastfeeding or Human Milk
- When available, breastfeeding should be the first choice to alleviate procedural pain in neonates undergoing a single painful procedure, such as venipuncture or heel lance (Codipietro, Ceccarelli, & Ponzone, 2008; Carbajal et al., 2003; Gray et al., 2002). Breastfeeding should not be discontinued prior to the procedure. Studies show that when breastfeeding was stopped shortly before a painful procedure, no significant differences were found (compared to control groups) in outcomes in terms of the orogustatory, emotional, tactile, or thermal experience (Gradin, Finnstrom, & Schollin, 2004). When breastfeeding is not possible, whether because of the unavailability of the mother or difficulties with breastfeeding, consider the use of expressed human milk by dropper, syringe, or bottle, which has been shown to soothe newborns experiencing procedural pain (Mathew & Mathew, 2003; Upadhyay et al., 2004; Taddio et al., 2008; Shah, Aliwalas, & Shah, 2006). Administration of human milk can also be combined with sucking, by dipping a pacifier (dummy) in the milk, as described below for sucrose.
- Although some studies have demonstrated the efficacy of human milk alone (Upadhyay et al., 2004; Shah, Aliwalas, & Shah, 2007), human milk may not be equivalent to breastfeeding because of breastfeeding's multicomponent experience. Breastfeeding throughout the painful procedure is likely to be superior to human milk alone on the basis of synergism between the components of breastfeeding (Gradin, Finnstrom, & Schollin, 2004; Shah, Aliwalas, & Shah, 2007).
- Coordinating a breastfeeding session with the timing of the procedure is best, but, if this is not possible, skin-to-skin contact can comfort infants undergoing a procedure such as a heel lance. Skin-to-skin contact also gives the mother a caretaking role during the procedure that is unobtrusive, and by diminishing infant stress, it can increase maternal confidence as to her value to the infant (Gray, Watt, & Blass, 2000).
- Parental contact and sucrose may act synergistically to reduce pain in neonates. Therefore if feasible, this combination can be employed (Schechter et al., 2007). Sucrose taste—first studied 20 years ago—is readily available for increasing the efficacy of other non-pharmacologic techniques (Gradin, Finnstrom, & Schollin, 2004). Sucrose administration is covered in more detail in the section below. Sucrose and pacifier can both be combined with the skin-to-skin component of parental contact.
Sucrose and Sucking (in Combination or Separately)
Sucrose taste has been shown to be effective analgesia for newborns and young infants for minor procedures, but not for more painful experiences like bladder catheterizations:
- Sucrose and pacifier. The combination of oral sucrose and pacifier or non-nutritive sucking is remarkably soothing (Blass & Watt, 1999). This technique offers pain reduction to infants undergoing a wide variety of painful procedures, including heel lance, umbilical or percutaneous venous or arterial catheter insertion, central venous line placement, subcutaneous or intramuscular injection, lumbar puncture, circumcision, and endotracheal suction (Anand, 2001; Stevens, Yamada, & Ohlsson, 2004; Stevens et al., 2005). Because pain reduction achieved when using both sucrose and non-nutritive sucking is similar to that with breastfeeding, using a pacifier (dummy) dipped in 24% sucrose (by weight) solution whenever breastfeeding is not possible is an effective option (Blass & Watt, 1999; Akman et al., 2002). Sucrose administration should begin 2 minutes prior to the procedure. If use of a pacifier is not an available or acceptable option, sucrose can also be combined with sucking by dipping a clean, gloved (or non-gloved parental) finger in the sucrose solution. If sucking a pacifier or finger is not an option, administer a sucrose solution orally before the procedure (Anand, 2001). When parents are present, they should be educated that sweet substances other than breast milk and pacifiers both are recommended in the newborn period only for procedural pain.
- Glucose versus sucrose. Glucose has also been shown to be an acceptable and effective alternative analgesic (Axelin et al., 2009; Idam-Siuriun et al., 2008). Taste difference is not a factor. Studies in rat (Blass & Shide, 1994) and human (Okan et al., 2007) newborns have not shown a preference for sucrose over glucose. The commercial availability of sucrose (table sugar) may have increased its use.
- Sucrose by syringe. If use of a pacifier is not possible, administer 0.5–2mL of a 24% sucrose solution orally via syringe 2 minutes before the painful procedure (Anand, 2001; Shann, 2007). Several 24% sucrose solutions are commercially available. Sucrose administered by oro- or nasogastric tube is not analgesic.
- Pacifier alone. While pacifiers alone may decrease crying associated with painful procedures, they do not have the same effect on physiological parameters such as heart rate or vagal tone (Taddio, 2001: Porges & Lipsitt, 1993). Moreover, sucking a pacifier has been found to reduce pain only when the suck rate exceeds 30 sucks/minute (Stevens, Yamada, & Ohlsson, 2004). A pacifier (or clean gloved or parental finger) should be used as the sole soothing intervention only if breastfeeding, human milk, sucrose (or glucose), and skin-to-skin contact are unavailable because non-nutritive sucking has consistently been found to be better than no intervention at all (Pinelli, Symington, & Ciliska, 2002).
- Sucrose better than human milk? At least one study indicates that sucrose is more effective than human milk, when both are administered orally via syringe, at reducing infants' cry time, recovery time (heart rate peak returns to baseline), and change in heart rate (Ors et al., 1999). The sugar in human milk is lactose, which has been shown to be an ineffective analgesic agent (Blass & Shide, 1994). The analgesic component of human milk may be attributed to its fat content or other constituents.
Soothing the Premature Newborn
Less research has been completed for this population, but there are several techniques that can be used to relieve pain in premature newborns. Breastfeeding may be problematic secondary to the medical status of the infant. Preterm infants may be medically compromised and/or may be developmentally unable to suck or swallow. In such cases, individual components of breastfeeding or a combination of the components of breastfeeding (e.g., contact and sweet taste) are available. Concerns about prolonged sucrose exposure in the premature infant are real. One study documented infants born at <31 weeks who were given a higher number of sucrose doses had lower scores in motor development and attention when assessed at term. There are no uniform gestational age criteria for studies on analgesia used in preterm infants. The following recommendations are based on studies of infants with an average gestational age of 30 weeks or greater. Not all studies have included infants between 28 and 30 weeks in gestational age, however, and it is unclear if the following recommendations are applicable to that age range. The data do not allow us to extrapolate these recommendations to the smallest premature infants (<27 weeks).
- Skin-to-skin contact provides effective pain reduction for premature newborns (Ludington-Hoe, Hosseini, & Torowicz, 2005; Johnston et al., 2003).
- In very-low-birth-weight neonates (27–31 weeks of gestation) undergoing consecutive heel lances, a pacifier dipped in sucrose or in water significantly reduced pain compared with infants who did not receive any intervention (Stevens et al., 1999).
- The value of sucrose as a pain reducer in the preterm infant is well established (Johnston et al., 2002; Ramenghi et al., 1996; Abad et al., 1996; Johnston et al., 1999). The recommended dosage in this population is 0.1–0.4mL of 24% sucrose solution. (Anand, 2001; Abad et al., 1996). Further pain reduction can be achieved when preterm infants receive 24% sucrose as three doses (0.1 mL, 2 minutes apart given 2 minutes and immediately prior to heel lance and 2 minutes after lance) rather than as a single dose (Johnston et al., 1999).
- The efficacy of breastfeeding and human milk as a pain reducer for the preterm or low-birth-weight infant is not well established in the current literature and should be the subject of further research; no studies have been performed specifically in this population. Regardless, if a mother wishes to breastfeed or provide her infant with human milk instead of sucrose, this should not be discouraged.
- Skin-to-skin contact plus sucrose has not been formally evaluated in premature infants, but may provide pain reduction for the preterm or low-birth-weight neonate.
Soothing the Older Infant (1 Month to 1 Year of Age)
Breastfeeding or its components as an analgesic technique has not been fully researched across this older population. For children older than a year, the focus of published literature is on the use of distraction techniques, which falls outside the scope of this protocol.
- Sucrose. Two recent meta-analyses of 10 and 14 randomized clinical trials (RCTs) on infant pain (Shah et al., 2009; Harrison et al., 2010) found sucrose to be an effective pain management strategy for infants and children up to 12 months of age. Two milliliters of 25% sucrose was effective during vaccination up to 6 months of age (Lewindon, Harkness, & Lewindon, 1998); however, 2mL of 24% sucrose was not effective for possibly more painful procedures like bladder catheterization in children older than 1 month of age (Rogers et al., 2006). Increasing the concentration of sucrose solution may be more effective as the infant ages (Harrison et al., 2010). One study explored the pain-relieving qualities of sucrose in children up to 48 months of age (Dilli, Kucuk, & Dallar, 2009) and found effectiveness compared to no treatment. Others, however, report lack of effectiveness with lower concentrations and younger ages (Lewindon, Harkness, & Lewindon, 1998; Barr et al., 1995). Sucrose taste alone was effective for one vaccination up to 12 months of age (Thyr et al., 2007) but did not demonstrate similar analgesia for multiple (three) vaccinations (Mowery, 2007). The higher concentrations of sucrose solutions may be more effective at older ages (Ramenghi et al., 2002); however, the majority of studies used differing concentrations, therefore precluding recommendations on the optimal concentration and dose (Shah et al., 2009; Harrison et al., 2010).
- Maternal/caretaker behavior. It has been noted that maternal behavior during a painful procedure accounts for up to 26% of infant pain behavior during both the procedure and the recovery period (Sweet & McGrath, 1998). Maternal distress was an especially important determinant of pain behavior in infants with low vagal tone compared to infants with high vagal tone (Sweet, McGrath, & Symons, 1999). Giving parents a caretaking role, such as securing or distracting the child, can reduce parental sense of helplessness. When parents are unavailable or unable to play a caretaking role, consider recruitment of another person (e.g., nurse) to help secure and/or distract the child (Schechter et al., 2007).
- If the infant is still breastfeeding, the mother should be invited to try it. Although the efficacy of breastfeeding and human milk as a pain reducer for older infants has not been extensively studied, there is potential benefit/minimal risk.
- The upper age limit of effectiveness of sucrose as a pain reducer has not been fully studied, and sucrose therefore cannot be recommended as a pain reducer in infants older than 12 months at this time (Schechter et al., 2007; Shah et al., 2009; Lewindon, Harkness, & Lewindon, 1998). A recent publication of workshop proceedings reviews the evidence for other techniques such as physical, psychological, and pharmacological interventions and has shown a range of non-pharmacologic treatments to be effective at reducing older childhood vaccine injection pain (Shah et al., 2009; Taddio et al., "Inadequate pain management," 2009; Taddio et al., "Physical interventions," 2009; Chambers et al., 2009).
