Neonates In The Neonatal Intensive Care Unit Experience Hundreds Of Painful Procedures At A Time Of Rapid Neurological Development. Although The Immediate Responses To Pain May Be Protective, The Potential Long-term Effects Of Early And Under-treated Pain Are Concerning. As Pain Assessment Is The First Step In The Provision Of Appropriate And Timely Pain Management, Attention Should Be Directed To The Quantification Of Pain In Terms Of Its Location, Severity, Intensity And Duration. Over The Past Decade, Numerous Pain Measures Have Been Developed For Preterm And Term Neonates, However, Most Of Them Have Been Developed For Research Purposes And Have Not Been Tested In The Clinical Setting. In Order To Effectively Implement Pain Measures In The Clinical Setting, The Psychometric Properties Of Reliability, Validity, Feasibility And Clinical Utility Must Be Established. This Review Paper Will Highlight The Importance Of Neonatal Pain Assessment And Examine The Psychometric Properties Of Various Measures Of Neonatal Pain. Pharmacological And Non-pharmacological Interventions To Manage Acute Pain In High-risk Neonates Will Be Addressed And Future Research Topics Will Be Proposed.

Context Hospitalized Infants Undergo Repeated Invasive Procedures. It Is Unknown Whether Cumulative Experiences With Pain Lead To Anticipatory Pain Behaviors And Hyperalgesia.

Objectives To Determine Whether Newborns Who Are Born To Mothers With Diabetes And Undergo Repeated Pain Learn To Anticipate Pain And Exhibit More Pain During A Painful Procedure Than Normal Infants.

Design, Setting, And Participants Prospective Cohort Study Of 21 Full-term Newborns Born To Mothers With Diabetes And 21 Born To Mothers With Uneventful Pregnancies, At A University Teaching Hospital Between August 1999 And October 2000. Infants Of Diabetic Mothers Underwent Repeated Heel Lances In The First 24 To 36 Hours Of Life For Monitoring Of Blood Glucose Concentrations. Pain Responses Of All Infants Undergoing A Venipuncture On The Dorsum Of The Hand To Obtain Blood For The Newborn Screening Test After The First Day Of Life Were Compared. In Addition, From September Through November 2001, 12 Infants Of Diabetic Mothers And 12 Normal Infants Were Compared For Pain Reactions To Intramuscular Vitamin K Injection After Birth.

Main Outcome Measures Percentages Of Time Observed Grimacing And Crying And Visual Analog Scale (vas) Scores.

Results Raters Were Blinded To Exposure Group. Median Baseline Scores For Grimacing, Crying Time, And Vas Did Not Differ Significantly Between Groups (p = .27, p = .32, And p = .32, Respectively). Median Scores (interquartile Range) For Grimacing During Skin Cleansing Were Higher In Infants Of Diabetic Mothers (22.2% [77.5%] Vs 0% [15%]; p = .03). The Vas Scores For Both Groups Were Zero, But The Distribution Of The Scores Was Significantly Different (86% Of Normal Infants Vs 52% Of Infants Of Diabetic Mothers Had Scores Of Zero) (p = .04). During Venipuncture, Infants Of Diabetic Mothers Had Higher Median Scores For Grimacing (81.7% [32.5%] Vs 40% [73.4%]; p = .01), Vas (69% [27.5%] Vs 5% [60.5%]; p = .002), And Crying (40.2% [77%] Vs 0% [54.8%]; p = .03) Compared With Normal Infants. There Were No Differences Between Groups On Any Pain Measure In Response To Intramuscular Injection.

Conclusions Newborns Who Had Diabetic Mothers And Were Exposed To Repeated Heel Lances In The First 24 To 36 Hours Of Life Learned To Anticipate Pain And Exhibited More Intense Pain Responses During Venipuncture Than Normal Infants.

Selective Serotonin Reuptake Inhibitors (ssris) And Benzodiazepines Are Frequently Used To Treat Maternal Depression During Pregnancy, However The Effect Of Increased Serotonin (5ht) And -amino-butyric Acid (gaba) Agonists In The Fetal Human Brain Remains Unknown. 5ht And Gaba Are Active During Fetal Neurologic Growth And Play Early Roles In Pain Modulation, Therefore, If Prolonged Prenatal Exposure Alters Neurodevelopment This May Become Evident In Altered Neonatal Pain Responses. To Examine Biologic And Behavioral Effects Of Prenatal Exposure, Neonatal Responses To Acute Pain (phenylketonuria Heel Lance) In Infants With Prolonged Prenatal Exposure Were Examined. Facial Action (neonatal Facial Coding System) And Cardiac Autonomic Reactivity Derived From The Relationship Between Respiratory Activity And Short Term Variations Of Heart Rate (hrv) Were Compared Between 22 Infants With Ssri Exposure (se) [fluoxetine (n = 7), Paroxetine (n = 11), Sertraline (n = 4)]; 16 Infants Exposed To Ssris And Clonazepam (se+) [paroxetine (n = 14), Fluoxetine (n = 2)]; And 23 Nonexposed Infants During Baseline, Lance, And Recovery Periods Of A Heel Lance. Length Of Maternal Ssri Use Did Not Vary Significantly Between Exposure Groups--[mean (range)] Se:se+ 183 (31-281):141 (54-282) D (p > 0.05). Infants Exposed To Se And Se+ Displayed Significantly Less Facial Activity To Heel Lance Than Control Infants. Mean Hr Increased With Lance, But Was Significantly Lower In Se Infants During Recovery. Using Measures Of Hrv And The Transfer Relationship Between Heart Rate And Respiration, Ssri Infants Had A Greater Return Of Parasympathetic Cardiac Modulation In The Recovery Period, Whereas A Sustained Sympathetic Response Continued In The Control Group. Prolonged Prenatal Ssri Exposure Appears To Be Associated With Reduced Behavioral Pain Responses And Increased Parasympathetic Cardiac Modulation In Recovery Following An Acute Neonatal Noxious Event. Possible 5ht-mediated Pain Inhibition, Pharmacologic Factors And The Developmental Course Remain To Be Studied.

Abstract

Recent studies show neonatal intensive care units (NICU) patients are not receiving appropriate pain treatment compared to their adult and pediatric counterparts. Untreated pain in the compromised infant results in long and short-term physical, emotional and mental complications. An opportunity exists among all the key players involved in infant care to benefit by collaborating to overcome barriers to achieving infant pain relief. A proposed solution that involves creating a systematic framework integrating health care provider education, policies and protocols, as well as conflict resolution resources that are regulated and monitored by the Joint Commission on Accreditation of Healthcare Organizations (JCAHO), is described and evaluated. Through empowerment, guidance, evaluation and legitimacy, the proposed solution provides an enduring means to ensure that NICU infants receive cost-effective adequate pain relief.

--------------------------------------------------------------------------------

Introduction

The Problem of Untreated Pain in NICU Infants

More than 370,000 neonatal intensive care unit (NICU) patients in the United States each year rely on their caregivers to provide for all their basic needs to help them sustain life. However, recent studies show that NICU infants are not medicated prior to procedures for which adults are routinely medicated (Rouzan, 2001). Pain management differences also exist between neonatal and pediatric patients. For example, "66% of pediatric intensive care unit patients...[compared to] 26% of NICU patients are likely to receive analgesia (Rouzan, 2001, p.59). Another study demonstrated that neonates "from 109 NICUs in the United States and 14 NICUs in Canada that underwent a variety of painful procedures did not receive pharmacological treatment or comfort measures" (Stevens, 2000, p.634).

Untreated pain in NICU infants results in short and long-term complications. In the compromised NICU patient, pain inhibits the body's ability to fight infection, resulting in longer and more expensive hospital stays. Research shows that the infant's neurological ability to create long-term memories is well developed (Furdon, 1998). Long-term studies following the development of infants showed that behavioral reactions, such as "disruptions in sleep, feeding patterns and maternal-infant interactions can persist long after the noxious stimuli has ended," demonstrating recall of pain (Rouzan, 2001, p.58).

Why is Pain Untreated in NICU Infants?

Several reasons exist for untreated pain in NICU patients. Medically accepted definitions of pain, such as "an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage, " provided by the International Association for the Study of Pain, are not applicable to NICU infants since they are unable to voice their perceptions of pain. Moreover, parents are often unaware about the availability of infant pain relief medication or may fear the adverse side effects of drugs used to treat neonatal pain (Franck, 1997).

Similarly, a lack of awareness among health care providers contributes to ineffective pain relief among NICU infants (Available at: 404 Not Found). Until the mid-1980s, NICU patients did not receive any analgesia or anesthetic before undergoing surgery or diagnostic procedures. While recent studies show that NICU infants do experience pain and the health care community has recognized a need to treat it, current research findings do not always coincide with health care provider and public beliefs about neonatal pain management (Franck, 1997, p.83). While there are no legal cases of a health care provider violating the standards of care for neonatal pain, research suggests that disciplinary actions may have occurred but are rarely reported (McGrath, 2000). Providing a means to assess, evaluate and reinforce health care providers' accountability is crucial to delivering adequate neonatal pain relief.

Cost also affects access to pain relief for NICU infants. With the advent of costly medical technologies to improve neonatal outcomes, the median cost per day is about $1,115 per day with the average length of a NICU stay being 49 days, adding up to a median total of $49,457 (Rogowski, 1999). Literature searches in the last five years revealed no figures about the cost of neonatal pain therapy. NICU infants, regardless of condition, race, gender, and socio-economic background are at a high risk of not receiving access to adequate pain therapies.

Policy makers and medical associations have also been slow to create and adopt standards supporting neonatal pain management (Stevens, 2000). Further, hospitals are often slow to adopt evidence-based research and use the data to develop protocols. The Joint Commission on Accreditation of Healthcare Organizations (JCAHO) passed new pain assessment standards for health care institutions on January 1, 2001, addressing adult and pediatric clients (available at: 404 Not Found); however, neonatal pain assessment was virtually ignored. Thus, many hospitals lack neonatal pain management protocols or a regulatory body to reinforce NICU pain management implementation.

Key Players in Neonatal Pain Management

For a neonatal pain management policy to be created, such a policy must take into consideration all of the stakeholders. Health care providers are expected to "do no harm" according to the Hippocratic Oath. Parents aim to protect their children. Insurers and hospital administrators seek to provide quality, cost-effective access to health care. Pharmaceutical companies seek to increase their product market share by expanding the application of therapy to various patient populations. Policy makers aim to create solutions to address the unmet needs of vulnerable populations. Most importantly, patients have a right to have their pain treated. There is a collaborative need and opportunity for the key players to provide cost-effective access to adequate pain relief to the NICU population.

--------------------------------------------------------------------------------

Proposal

A Proposal for Solving the NICU Pain Management Problem

One proposed solution to the NICU infant pain control problem is a synthesis of suggestions that integrates Carlson's nationwide mandated NICU health care provider education, led by neonatal nurse practitioner staff, with Franck's development and implementation of health care institution neonatal pain assessment and management protocols, and conflict resolution resources (Carlson, 1996, p.68, Franck, 1997, p.85). This author recommends that all of these components should subsequently be evaluated by JCAHO. "Much of the work required to improve the management of pain in infants must occur at the organizational level" (Franck, 1997, p.84). One study supported the strength of a regional medical center's NICU's pain assessment, management and evaluation protocols and policies by demonstrating a "decreased length of time of extubation, decreased length of stay, better fluid management, and reduced side effects of narcotics" (Furdon, 1998, p.58). Health care institution protocols provide a standard that would include "a minimum standard frequency of pain assessment, standardized method of documentation, [and] guidelines for starting and escalating therapy" (Franck, 1997, p.85). Additional benefits included "improved pain management documentation, decreased cost, and decreased nursing time" (Furdon, 1998, p.58).

The proposed program reaches individuals who influence hospital policy, such as hospital administrators and executives. Conflict resolution methodologies would involve ethicists, parents and NICU health care providers to help facilitate open, multidisciplinary discussion of cases for which usual methods do not resolve a patient's pain (Franck, 1997). JCAHO can specifically create neonatal pain assessment and treatment standards to monitor and reinforce health care institutions' policies and protocols. The integration of health care provider education, institutional protocols, policies, and conflict resolution resources, with JCAHO reinforcing and regulating neonatal pain assessment, diagnosis and treatment, creates a system that can effectively provide adequate neonatal pain management.

As "clinicians, educators, researchers, advocates, managers and consultants" -- roles that are necessary for "greater understanding of the neonatal pain phenomenon" -- neonatal nurse practitioners are well suited to educate other health care team members (Carlson, 1996, p.65). The combination of skills required within these roles uniquely positions neonatal nurse practitioners to assess, diagnose, treat and emotionally support neonatal patients and their families. Through health care provider education, parents would be empowered to serve as advocates for their infants. Health care providers would be better equipped to handle the demands of families and patients by being educated about the latest in neonatal pain therapies, fulfilling their professional commitment to reduce suffering, and patients would have their pain treated.

Evaluating the Proposal: Strengths and Limitations

The greatest strength of the proposed solution is that it presents advantages to all the key players involved in neonatal pain management, including patients, families, health care providers, insurers, pharmaceutical companies, regulatory bodies and ethicists. First, health care providers would be able to better discern how, when and what treatment method should be used. Pharmaceutical companies could collaborate with health care providers to fund medical education programs, which will ultimately drive product usage and increase market share. To maintain their JCAHO accreditation status, hospital administrators would monitor the implementation of neonatal pain management protocols and policies to meet JCAHO standards cost-effectively and to attract patients to the hospital. Families would benefit by knowing that a JCAHO-accredited hospital is caring for their infant, has passed certain pain management standards, and could use accreditation as a factor in selecting a health care facility for treatment. Insurers would benefit by having established protocols serve as pain management reimbursement guidelines. Patients would have a system of protocols, policies and conflict resolution resources, providing many opportunities to obtain pain relief. Involving ethicists in conflict resolution would provide a different perspective to address problems. Most importantly, this program would provide the necessary long-lasting systematic framework to cost-effectively reinforce access to adequate neonatal pain relief.

Used in isolation, educational campaigns, protocols and policies do not provide the necessary framework to provide adequate pain relief for NICU patients. Education alone does not always result in a lasting change in behavior, particularly for health care providers who have an ingrained way of performing procedures (Franck, 1997). To ensure implementation, protocols and policies need to be reinforced and monitored through a designated regulatory body. Moreover, patients with a complicated clinical profile, requiring care that is not met by the health care institution's policies and protocols, need conflict resolution resources.

However, there are limitations to the proposed policy program. First, such a program may take years to create and implement because it would need to pass through a bureaucratic approval process involving hospitals, health care providers, medical organizations, JCAHO, pharmaceutical companies and insurers. Thus, many patients may miss the benefits of such a program. Large costs may be associated with creating educational materials and developing protocols.

Yet, the program's long-term viability incrementally lessens the sunk cost in the establishment of the program. Thus, the lasting effect of the proposed solution significantly outweighs and justifies the time and costs it will take to implement. The program creates an educational platform to empower, standards to guide and evaluate care, as well as a reinforcement body to ensure legitimacy. By providing advantages to all the major players, the proposed program motivates all of the stakeholders to help achieve the delivery of cost-effective access to adequate neonatal pain relief, resulting in a long-term solution.

--------------------------------------------------------------------------------

Conclusion

Untreated pain leads to suffering and further complications, which ultimately results in longer hospital stays as well as greater costs to society at large. While assessing and diagnosing pain in neonatal patients is challenging, it is a problem that can be resolved through the proposed systematic framework of protocols, conflict resolution resources and enforcement that involves and benefits all the key players. The system is sustained by protocols that help define and guide the roles of all the key players, conflict resolution offers an outlet to deal with ambiguity, and enforcement through JCAHO lends legitimacy, providing a collaborative win-win situation for all players that will encourage them to perpetuate the continuation of the system. Despite the long road it will take to create and implement such a program, the promise of cost-effective access to adequate neonatal pain management will outweigh the emotional and financial costs that we currently and will continue to pay without having one in place.

Pediatric Pain Management staff education

Top 10 things you need to know about pediatric pain management:

Infants do have PAIN.

If a child is lying still, pain may be present. Children may not always be willing or able to communicate the fact that they are in pain.

When there is pain, there may be nausea. Treat both.

Don't UNDERMEDICATE. Children often require more pain medication than adults (in milligrams/ kilogram) do to achieve pain control. Repeat patients usually need more medication to attain the same degree of pain relief.

Incorporate the family into the child's care, since family insights are very helpful at all ages and developmental stages.

When assessing the effect of pain medications, remember to consider the patient's normal routine. If it's naptime the child may not arouse easily. Pain medication may not be the problem.

Titrate pain medication in increments is when possible. Monitor respiratory status if narcotics are being used.

Always consider other reasons for patient discomfort besides pain. Is the child wet or hungry? Does she want her parents? Does he need to be burped?

Communicate at the child's level when assessing pain and response to pain, remembering that many children regress when in pain.

Seek other pediatric personnel as consultants whenever necessary.

Assessment and Documentation

Pain Assessment

A physician, nurse, and/or other health care professional will identify the presence of pain for each patient encounter at UMHHC. If pain is present, its intensity is scored, typically using a standardized 0 to 10 scale. (See "pain scales" below). Pain scores are documented in writing, just like vital signs, making them readily available to all members of the health care team. The American Pain Society actually suggests that pain should be thought of as the 5th vital sign.

In the hospital setting, the patient's pain is assessed at least as often as vital signs are taken, because ongoing assessment is necessary to evaluate changes in pain and the effectiveness of its treatment. Pain should be assessed at intervals appropriate to the severity of pain and the patient's situation. For many patients, this will mean assessment of pain every 4 hours, but the time between assessments must be individualized to the patient's need.

In the ambulatory care setting, pain assessment should be completed with every new episode of care. Repeated visits or contacts for the same problem may not require repeated pain assessments (unless a current pain problem is being followed).

Pediatric Pain assessment should be appropriate to the developmental level. All pediatric patients should be assessed for pain. Pain can be communicated by words, expressions, and behavior (crying, guarding a body part, grimacing).

Using the QUEST Principles of pain assessment (Baker and Wong, 1987) may be helpful in assessing pediatric pain.

Question the child.

Use pain rating scales.

Evaluate behavior and physiological changes.

Secure parent's involvement.

Take cause of pain into account.

Take action and evaluate results.

Neonates:

Situations that are painful for older children and adults can be expected to be painful for babies. Neonates that are ill may not be able to cry.

I really appreciate these articles. Our unit is undergoing some major changes to standardize our treatment of pain. I find the biggest barriers are all the conflicting information. For instance, one of the most simple ways of soothing a baby is using a soother dipped in sugar water or breast milk, but some of the breastfeeding nazis have the parents so scared of nipple confusion that they won't allow a soother. Another issue is baby's on the vents. Some of the docs will sedate wrangy kids, but others actually prefer that they fight against the vent.

Classification of Pain by Inferred Pathology

Two Major types of Pain

I Nociceptive Pain

a. Somatic Pain

b. Visceral Pai

II Neuropathic Pain

a. Centrally Generated Pain

b. Peripherally Generated Pain

Nociceptive Pain: Normal processing of stimuli that damages normal tissues or has the potential to do so if prolonged; usually responsive to nonopioids and/ or opioids.

A. Somatic Pain: Arises from bone, joint, muscle, skin or connective tissue. It is usually aching or throbbing in quality and is well localized.

B. Visceral Pain: Arises from visceral organs, such as the GI tract and pancrease. This may be subdivided:

1. Tumor involvement of the organ capsule that causes aching and fairly well-localized pain.

2. Obstruction of hollow viscus, which causes intermittent cramping and poorly localized pain.

Neuropathic Pain: Abnormal processing of sensory input by the peripheral or central nervous system; treatment usually includes adjuvant analgesics.

A. Centrally Generated Pain

1. Deafferentation pain. Injury to either the peripheral or centeral nervous system. Examples: Phantom pain may reflect injury to the peripheral nervous system; burning pain below the level of a spinal cord lesion reflects injury to the central nervous system.

2. Sympathetically maintained pain. Assoicated with dysregulation of the autonomic nervous system. Examples: May include some of the pain associated with reflex sympathetic dystrophy/causalgia (complex regional pain syndrome, Type I, Type II)

B. Peripherally Generated Pain

1. Painful polyneuropathies. Pain is felt along the distribution of many peripheral nerves. Examples: Diabetic neuropathy, alcohol-nutritional neuropathy, and those associated with Guillain-Barre' syndrome.

2. Painful neuropathies. Usually associated with a known peripheral nerve injury, and pain is felt at least partly along the distribution of the damaged nerve. Examples: nerve root compression, nerve entrapment, trigeminal neuralgia.

Wow! That's awesome! Thank you, Dave!

Does anyone have any research based evidence stating that it is beneficial to wean Pain meds, or that it can be detrimental the neonate if not done? Many times in out NICU, a baby may be on a Fentanyl drip and the next day it is d/ced all together. We'd like to start a protocol for weaning.

Specializes in NICU, PICU, educator.

We wean ours always..we have had kids go into withdrawl and actually seize! We wean by 10% per day as tolerated...we use the Neonatal Abstinence Scores to determine this. We have also changed some kids over to Methadone and weaned them from that as we can change that to an oral form if the baby is taking a long time to wean from narcs. I went to a seminar and it has been documented that most neonates can become dependent on narcs within 24 hours...I don't have the exact source, but I remember that from this talk.
