Essay Example on Neonatal Pain Management

Newborns, including preterm and terms, experience pain and thus have the right to receive adequate and effective pain reliefs. When newborns are compared to an adult, a neonate demonstrates more sensitivity towards sensory stimuli and therefore is much more prone to the consequences of pain. Neonates cannot also verbalize when in pain and depend on the caretaker's skill to assess, recognize, and manage the pain effectively. There are instances whereby clinicians have been accused of not practicing the correct approaches when managing pain neonates with pain effectively. In this study, there will be an evaluation of current guidelines on assessing, preventing, and managing pain in a neonate. This review aims to improve how clinicians evaluate and treat pain in neonates through the utilization of specialized pain assessment tools with particular focus on acute pain associated with medical and surgical ailments.

Assessing pain in a neonate is challenging, and although there are different pain scoring systems, there still lacks a universal approach in assessing pain in neonates (Witt et al.,2016, pp 1-5). There also seems to be minimal understanding of different ways pain is perceived by and the adverse effects that follow if the pain is left untreated (Witt et al.,2016, pp 1-5). The American Academy of Pediatrics, in conjunction with the Canadian Pediatric Society, established a policy in 2006 indicating that all health care centers were to create neonatal pain programs with the aim of assessing pain frequently, reducing the painful procedures conducted, and reducing and preventing acute pain in invasive procedures.

Developed countries have advanced medical and technological advancement, which means that extremely vulnerable premature babies and term babies with advanced diseases survive often survive. (Bhalla & Shepherd, 2014, p. 89). However, diagnostic procedures and treatment can cause pain in the neonate. All newborns have to go through at least one procedure that is painful in their initial days of life. The impact of this pain may have short and long-term implications. Despite this, pain in neonates is sometimes undertreated, underrecognized, and regularly not reassessed or evaluated (Bhalla & Shepherd, 2014, p. 89). Pain management remains unevolved in developing countries since there can be assumptions that neonates cannot experience pain (Witt et al.,2016, pp 1-5).

Pain assessment in a neonate or a nonverbal child is a challenging task and requires skill. There are pain scales that make this process less daunting. However, there are differences in the scales and methods available since, and there still lacks a universal method for assessment. Objective data, such as blood pressure, heart rates, and cortisol levels, can be utilized. Still, they rarely are since most physicians rely on crying, grimace, and the overall mannerisms of the neonate to make a diagnosis (Witt et al.,2016, pp 1-5). In addition to the variations existing in pain scales, they are many other variations that can affect the pain perception in neonates. Anxiety is a significant factor in pain perception in children and adults (Witt et al.,2016, pp 1-5). It can be difficult to establish the impact of being in a new environment such as emergency or exam rooms in a neonate (Coakley & Wihak,2017, p.9). It is also often overlooked in the assessment of pain on whether the clinician has adequate sills and willingness to assess signs of illness in children.

The Joint Commission has a set of standards implemented in health care facilities making pain assessment compulsory for all patients (Witt et al.,2016, pp 1-5). The standard numeric scale is usable in verbal children, and there are scales validated to assess pain in children as young as three years old. Revised FACES scales such as the Wong-Baker Faces scale plus the 10 cm visual analog scale are utilized in different health care facilities to assess pain in pediatric patients (Witt et al.,2016, pp 1-5). Apart from assessing pain through physiologic frameworks in neonates, there are other varied pain scales utilized in newborn intensive care units (NICUs). Examples being the neonatal infant pain scale (NIPS), neonatal pain, agitation and sedation scale(N-PASS), neonatal facial coding system (NFCS) and cry, required oxygen, increased vital signs, expression, sleeplessness scale (CRIES) which are all used to assess neonates(Witt et al.,2016, pp 1-5).

Pain in neonates is managed best when there is the utilization of different approaches, including pharmacological and non-pharmacological ways (Bhalla & Shepherd, 2014, p. 89). Although it is well studied in adults, few studies have attempted to evaluate the pharmacodynamics and pharmacokinetics in infants and neonates in general. There are different variables in a neonate, including drug interactions, malnutrition, and low plasma proteins that affect how the drug is distributed in the body (Bhalla & Shepherd, 2014, p. 89). There are no specific guidelines set to help identify these problems and the effects they cause on specific analgesics. These factors should be considered when picking an appropriate dose or route of administration.

The most basic mechanism of action of non-steroidal anti-inflammatory drugs (NSAIDs) such as Acetaminophen is inhibition of cyclooxygenase, an enzyme responsible for producing prostaglandins (Lucas et al.,2019, p.124). This occurs in the central nevus system and the peripheral system. NSAIDs are said to have a longer half-life in infants and neonates since their hepatic enzymes are still immature, and there is still minimal glomerular filtration rates (GFRs) (Lucas et al.,2019, p.124). Currently, there are three types of NSAIDs available in IV form, including ibuprofen, ketorolac, and Indomethacin (Witt et al.,2016, pp 1-5). Indomethacin and ibuprofen pharmacokinetics have been studied extensively in neonates in regard to the closure of patent ductus arteriosus (PDA) but haven't been studied as extensively in investigating their analgesic effect in neonates (Witt et al.,2016, pp 1-5).

In preterm infants diagnosed with PDA, the occurrence of renal insufficiency and necrotizing enterocolitis is less when ibuprofen is preferred to indomethacin, but a prophylactic dose of indomethacin in high-risk neonates is associated with a decreased rate of intraventricular hemorrhage than the administration of ibuprofen (Witt et al.,2016, pp 1-5). Neither medication has been associated with improvements when used in the long term to treat PDA (Witt et al.,2016, pp 1-5). Ketorolac remains the most commonly used NSAID in infants and neonates, but data on the drug's efficacy and safety is usually retrospective and anecdotal. In one of the retrospective studies that included infants below six months, there were reports of no adverse effects of the drug on the neonates despite the drug being known to alter renal and platelet functions.

Meanwhile, the use of opioids in neonates is minimal, with pharmacokinetics being altered, accompanied by significant interpatient variability (Bhalla & Shepherd, 2014, p. 89). Decreased GFR in neonates leads to lower plasma clearance, a decrease in protein binding, and increased volume of distribution (Bhalla & Shepherd, 2014, p. 89). These factors are compounded by other complications related to acute diseases and prematurity, which all lead to change in opioid pharmacokinetics. The widely used medications in the neonatal population are morphine and fentanyl (Witt et al.,2016, pp 1-5). Requirements of Opioids are highly variable in neonatal patients, and clinicians are thus responsible for the careful titration to achieve adequate levels of sedation while preventing adverse effects.

Nonpharmacological methods of pain control are also useful in neonates. Some of these methods include administration of oral glucose or sucrose, breastfeeding, or skin to skincare contact, which is also referred to as Kangaroo care, sensorial saturation, swaddling, and nutritive suckling (Witt et al.,2016, pp 1-5). The most investigated non-pharmacological way has been the use of glucose with the hypothesis that different forms of glucose can lead to the endogenous release of opioids through mechanisms that are unknown (Silva, 2011, p.228). It has been established that glucose can significantly lower pain secondary to procedures. Measures of physiologic response, including heart rates, vagal tone, and oxygen saturation, are affected when different neonates were given placebos and some forms of glucose (Silva, 2011, p.228). When sucrose is preferred against breast milk or pacifiers, there was much more change in behavioral indicators of pain like grimacing or pain.

If a neonate is going through a painful procedure, then an alternative to glucose is breastfeeding or breast milk (Witt et al.,2016, pp 1-5). It has been determined that breast milk is helpful in one-time procedures. Neonates, being breastfed during venipunctures and heel stick procedures, demonstrated a substantial decrease in their physiologic responses like holding on to the mother and swaddling (Silva, 2011, p.228). The used parameters measured and showed decreased heart rates and reduced time neonates took to calm down after crying. In this population of neonate's diverse environmental interventions have proved to be effective in reducing pain, particularly when combined with other adjunctive therapies like breastfeeding or sweet solutions (Witt et al.,2016, pp 1-5). Kangaroo care is an effective tool for reducing pain in all physiologic parameters. Facilitated tucking involving flexing a neonate's arms and legs manually and swaddling have been known to stimulate self-soothing and are useful measures to reduce pain.
