Pain

Nursing Diagnoses:

Acute Pain/Chronic Pain/Impaired Comfort

related to the disease process, injury, or surgical procedure

Desired Outcome:

The patient's subjective report of pain using a pain scale, family's report, and behavioral and/or physiologic indicators reflect that pain is either reduced or at an acceptable level within 1-2 hr.

ASSESSMENT/INTERVENTIONSRATIONALES
Obtain history about ongoing/previous pain experiences and previously used methods of pain control. Elicit what was/was not effective. Consider whether pain is acute, chronic, or acute with an underlying chronic component.A pain history enables development of a systematic approach to pain management for each patient, using information gathered from pain history and the hierarchy of pain measurement (self-report, pathologic conditions or procedures that usually cause pain, behavioral indicators, report of family, and physiologic indicators). The Agency for Health Care Research and Quality (AHRQ, 2013) and the American Pain Society (APS, 2008) state that self-report of pain is the single most reliable indicator of pain.
Use a formal patient-specific method of assessing self-reported pain when possible, including description, location, intensity, and aggravating/alleviating factors.
Assess for behavioral and physiologic indicators of pain at frequent intervals (e.g., during scheduled vital signs [VS] assessments). Document responses.
Teach patients that pain assessment and management are not only a part of their treatment but also their right.Patients have the right to appropriate assessment and management of their pain (TJC, 2013).
Accept the patient's report of pain and plan interventions based on this report.A patient's self-report should be the primary source of pain assessment when possible (AHRQ, 2013; APS, 2008).
Evaluate the patient's health history for alcohol and drug (prescribed and nonprescribed) use, which could affect effective doses of analgesics (i.e., patient may require more or less). Ensure that the surgeon, anesthesiologist, and other health care providers are aware of any significant findings. Consult a pain management team if available.Other medication use could alter effective doses of analgesics or lead to undertreatment. All care providers must be consistent in setting limits while providing effective pain control through pharmacologic and nonpharmacologic methods. Psychiatric or clinical pharmacology consultation may be necessary.
Develop a systematic and collaborative approach to pain management for each patient, using information gathered from pain history and the hierarchy of pain measurement.American Nurses Association & American Society for Pain Management in Nursing (2005) identifies importance of involvement of patient, family, and other health care providers in data collection, formulation of outcomes, and development of the pain management plan. The AHRQ (2013) and APS (2008) state self-report of pain is the single most reliable indicator of pain.
imageUse at least two identifiers (e.g., patient's name, medical record number) before administering medications.Using two or more identifiers improves accuracy of patient identification in keeping with The Joint Commission (TJC, 2013) National Patient Safety Goals promoting the right patient receiving the right medication.
Use a preventive approach: administer prn pain medications before pain becomes severe as well as before painful procedures, ambulation, and bedtime.Prolonged stimulation of pain receptors results in increased sensitivity to painful stimuli and the need to increase the amount of drug required to relieve pain.
Administer analgesics according to the World Health Organization (WHO) three-step analgesic ladder.
Recognize that choice of analgesic agent is based on three general considerations: therapeutic goal, the patient's medical condition, and drug cost.Individualized therapeutic goal and the stage of illness/disease process are important factors in agent selection to maximize pain relief and minimize potential of adverse side effects. The difference in cost of different agents used to accomplish the same goal may be large. Where there is no proven or expected benefit of using one medication in preference to another to accomplish a desired goal, the less costly medication should be considered. The right medication is the one that works with the fewest side effects.
Also consider convenience, anticipated analgesic requirements, side effects, and patient's previous experience with a specific agent or patient's recall of side effects experienced with a specific agent, including route.The preferred route is the one that is least invasive while achieving adequate relief. Aversion to painful routes of delivery (e.g., subcutaneous, intramuscular [IM]) may lead to underreporting of pain by patients and to undermedication by nurses.
imageUse acetaminophen with caution. Be alert to the total amount of acetaminophen a patient is receiving through over-the-counter and other combined medications.Dose adjustments are required for patients with impaired liver/renal function. For adults, the American Liver Foundation (2008) recommends acetaminophen not exceed 3 grams in 24 hr. Acetaminophen may cause serious skin reactions in some people, Stevens Johnson syndrome (see description in “Caring for Patients with Human Immunodeficiency Virus,” p. 524), or toxic epidermal necrosis. Acetaminophen may be given IV for patients unable to tolerate oral agents.
imageUse COX-2 selective NSAIDs and NSAIDs with caution.NSAIDs and COX-2 selective NSAIDs should be used with caution in patients with a history of duodenal bleeding ulcer; preexisting renal impairment; advanced age; concomitant use of corticosteroids, anticoagulants, warfarin, heparin; or history of long-duration NSAID therapy. The Food and Drug Administration (FDA) alerts and manufacturers' withdrawals of rofecoxib (Vioxx) and valdecoxib (Bextra) mandate that all health care providers remain current and assess risks/benefits based on current information, safety data, and availability.
As prescribed, administer opioid analgesics (e.g., morphine) for pain of greater severity.Morphine is the standard of comparison for opioid analgesics, and morphine or related “mu” (µ) receptor agonists are preferred when possible.
imageUse meperidine and normeperidine, a metabolite of meperidine, with caution.Normeperidine is a central nervous system (CNS) excitotoxin, which with repetitive dosing may produce anxiety, muscle twitching, and seizures. Patients with impaired renal function and those taking monoamine oxidase (MAO) inhibitors are particularly at risk. Recommended use is for less than 48 hr for acute pain in patients without renal or CNS dysfunction or dose less than 600 mg/24 hr (APS, 2008). In low doses meperidine has a role in alleviating shivering associated with general anesthesia and some biologic agents.
imageDo not use naloxone (Narcan) to attempt to reverse normeperidine toxicity.Naloxone does not reverse normeperidine and may potentiate hyperexcitability.
imageIf use of naloxone is necessary, titrate with caution.Too much too fast can precipitate severe pain, hypertension, tachycardia, and even cardiac arrest. More than one dose is sometimes necessary because naloxone has a shorter duration than most opioids.
imageDo not administer mixed agonist-antagonist analgesics concurrently with morphine or other pure agonists because reversal of analgesic effects may occur.Mixed agonist-antagonist agents such as butorphanol (Stadol) and pentazocine (Talwin) produce analgesia by binding to opioid receptors, while blocking or remaining neutral to the µ receptors. To date, there is no convincing evidence that agonist-antagonists offer any advantage over morphine-like agonists in the treatment of acute pain. Mixed agonist-antagonist agents may be useful in patients who are unable to tolerate other opioids.
imageAssess patients receiving opioid analgesics for level of pain relief and potential side effects, including evidence of excessive sedation or respiratory depression (i.e., RR less than 10 breaths/min or Spo2 less than 90%-92%). In the presence of respiratory depression, reduce amount or frequency of the dose as prescribed. Have naloxone readily available to reverse severe respiratory depression.Sedative effects precede respiratory depression. Close monitoring of sedation level may prevent respiratory depression.
imageMonitor older adults and individuals with chronic obstructive pulmonary disease, obstructive sleep apnea, asthma, and other respiratory disorders closely for respiratory depression and excessive sedation when they are receiving opioid analgesics. Consider using reduced doses and titrate carefully.Older adults who are opioid naive and patients with coexisting conditions are at higher risk of respiratory depression. The most critical time for monitoring for respiratory depression is the first 24 hr of opioid therapy in these populations (Pasero & McCaffery, 2011). Increased tolerance to respiratory depression occurs over days to weeks. Therefore, patients who are opioid naive (or have coexisting conditions) are at greater risk of respiratory depression than the patient who has been receiving an opioid for a week or more.
Wean patients as prescribed from opioid analgesics by decreasing dose or frequency.In general, doses should be reduced by no more than 10%-20% per day with vigilant assessment for withdrawal signs and symptoms.
Convert to oral therapy as soon as possible. When changing route of administration or medication, be certain to use equianalgesic doses of the new medication.Note: Changing the route of medication administration often results in inadequate pain relief because of ineffective equianalgesic conversion.
More opioid is required to produce respiratory depression than to produce sedation. Sedative effects precede respiratory depression. Close monitoring of the level of sedation and respiratory status may prevent respiratory depression.
Consult with the health care provider to discuss converting to scheduled dosing with supplemental prn analgesics when pain exists for 12 hr out of 24 hr.Experts recommend around-the-clock (ATC) dosing for patients with continuous pain because it provides superior pain relief with fewer side effects (APS, 2008). Prolonged stimulation of pain receptors results in increased sensitivity to painful stimuli and the need to increase the amount of drug required to relieve pain. Addiction to opioids occurs infrequently in hospitalized patients.
Titrate the dose to achieve the desired effect.The initial effect and duration of action of analgesics may differ vastly in acutely ill older adults who may require lower doses, whereas higher doses may be required for those with opioid tolerance or polysubstance use. It is important to consider factors such as these that can influence the initial effect and duration of action due to variations in the metabolism of analgesics. The goal is to develop a safe and effective pain management plan.
Provide patient-controlled analgesia (PCA) as prescribed.
imageIncrease patient monitoring following initiation, during the initial 24 hr, and at night when the patient may hypoventilate. Do not assume pain is controlled; assess the patient to determine if relief has been obtained.Monitoring involves pain, sedation, and respiratory assessments and may include Spo2 and capnography. Safety issues with PCA have been described with suggested strategies to reduce risk in ISMP Medication Safety Alerts (2008, 2009, 2013).
Monitor patients in whom neuraxial analgesia is used based on drug(s) being administered, catheter placement, and drug concentration and volume.Neuraxial analgesia (spinal, epidural, and caudal) is a widely used option for regional analgesia. It decreases many side effects associated with intravenous opioids, and there is evidence it can lead to increased mobility and postoperative recovery. Local anesthetics, opioids, steroids, and clonidine are examples of agents that may be used.
For local anesthetics, monitor motor examination/sensory level and pain intensity.Assessments may include sensory level and motor examination evaluations, level of pain intensity, sedation level, VS, and side effects. Potential side effects/complications include catheter migration, occlusion, hematoma, respiratory depression, hypotension, nausea/vomiting, urinary retention, and pruritus. For local anesthetics sensory assessments are performed bilaterally along dermatomes.
For opioids, monitor respiratory rate, sedation level, and pain intensity.Signs of local anesthetic systemic toxicity (LAST) are metallic taste, unusual sensations around and inside the mouth, ringing in the ears, muscle twitching, and confusion.
As prescribed, use analgesic adjuvants/co-analgesics.These agents are used to prolong and enhance analgesia, not specifically to treat isolated incidents of anxiety or depression.
imageAvoid substituting sedatives and tranquilizers for analgesics.
Assess for and report analgesia side effects. For management of constipation, see Constipation in “Prolonged Bedrest,” p. 68.Other analgesia side effects can include sedation, respiratory depression, nausea/vomiting, pruritus, and hypotension.
Augment action of the medication by advising nonpharmacologic methods of pain control, including weight reduction, physical therapy, cognitive behavioral therapies, acupuncture, massage, and biofeedback. Other methods include reflexology, acupressure, Reiki, thermotherapy, back and foot massage, range-of-motion exercises, transcutaneous electrical nerve stimulation, distraction, relaxation exercises, and guided imagery.Patients in whom nonpharmacologic interventions may be most successful include those who express interest in the approach, express anxiety or fear, or those with inadequate relief with pharmacologic management (ASA, 2012). Many of these techniques may be taught to and implemented by the patient and significant other.
Maintain a quiet environment and plan nursing activities to enable long periods of uninterrupted rest at night.Promoting rest and sleep may decrease level of pain.
Evaluate for and correct nonoperative sources of discomfort.Such sources including uncomfortable positioning, full bladder, and infiltrated IV site can be corrected readily without resorting to drug use.
imageCarefully evaluate the patient if sudden or unexpected changes in pain intensity occur, and notify the health care provider immediately should this occur.This may signal complications such as internal bleeding or leakage of visceral contents.
Document efficacy of analgesics and other pain control interventions using a pain scale or other formalized method.This documentation communicates level of pain relief obtained, interventions, effectiveness of the interventions, and ongoing follow-up to meet the analgesic goal.
