CHAPTER 21 Acute Pain Management Jaime C Paz Danika Quinlan CHAPTER OUTLINE CHAPTER OBJECTIVES Pain Evaluation Physical Therapy Considerations for Pain Evaluation Pain Management Physical Therapy Considerations for Pain Management The objectives of this chapter are to provide the following: An overview of pain evaluation scales most applicable to the acute care setting A description of physical therapy considerations when evaluating pain An overview of commonly utilized management strategies for acute pain including pharmacologic agents A brief description of physical therapy management strategies for acute pain PREFERRED PRACTICE PATTERNS Pain is multifactorial in nature and applies to many body systems For this reason, specific practice patterns are not delineated in this chapter Please refer to Appendix A for a complete list of the preferred practice patterns in order to best delineate the most applicable practice pattern for a given diagnosis This chapter provides information on the evaluation and management of acute pain with the goal of facilitating patient care The characteristics of acute pain include less than months in duration, often associated with tissue damage such as surgery or traumatic injury, the cause of pain is easily recognized, pain can be treated readily, and the duration of pain is predictable.1 Acute pain in the medical patient may result from nonsurgical abdominal pain, renal or biliary stones, and phantom limb pain.2 Pain Evaluation The subjective complaint of pain is often difficult to objectify in the inpatient setting Patients may be mechanically ventilated, pharmacologically sedated, or in too much pain to articulate their discomfort.3 Furthermore, patients who may be cognitively impaired are at higher risk for their pain to be undertreated with a resultant decreased quality of life.4-6 Despite these difficulties, an effective pain treatment plan depends on an accurate evaluation of the patient’s pain.7,8 Each evaluation requires a complete physical and diagnostic examination of the patient’s pain The criterion standard for pain assessment is through self-report by the patient because it is the most accurate indicator of the existence or intensity of his or her pain, or both.4,5,9 The goal for evaluation should be directed toward individualization while maintaining consistency among patients To assist with this process, various pain-rating tools have been developed to address both verbal and nonverbal (conscious or unconscious) patients Verbal pain scales (Table 21-1) include: • Numeric rating scale (NRS) • Visual analog scale (VAS) • Verbal descriptor scale (VDS) • Wong-Baker Faces Scale • Functional pain scale Nonverbal pain scales include: • Adult Nonverbal Pain Scale (Table 21-2) • Behavioral Pain Scale (Table 21-3) 457 458 CHAPTER 21    Acute Pain Management TABLE 21-1  Verbal Pain Scales Tool Description Verbal descriptor scales Numeric Rating Scale (NRS) The patient describes pain by choosing from a list of adjectives representing gradations of pain intensity The patient picks a number from to 10 to rate his or her pain, with indicating no pain, and 10 indicating the worst pain possible Visual Analog Scales (VAS)   Line scale   Wong-Baker Faces scale Functional Pain Scale The patient marks his or her pain intensity on a 10-cm line, with one end labeled “no pain,” and the other end labeled “worst pain possible.” The patient chooses one of six faces, portrayed on a scale that depicts graduated levels of distress, to represent his or her pain level A zero (0) to five (5) scale with corresponding pain descriptions = No pain = Tolerable (and does not prevent any activity) = Tolerable (but does prevent some activities) = Intolerable (but can use telephone, watch TV, or read) = Intolerable (cannot use telephone, watch TV, or read) = Intolerable (and unable to verbally communicate because of pain) Data from Kittelberger KP, LeBel AA, Borsook D:

nonverbal critically ill adults, Dimens Crit Care Nurs 22:260-267, 2003 HR, Heart rate; RR, respiratory rate; SBP, systolic blood pressure Pain scales used for both verbal and nonverbal patients include: • Face, Legs, Activity, Cry, Consolability (FLACC) scale (Table 21-4) • Critical Care Pain Observational Tool (CPOT) (Table 21-5) The validity of these scales may be improved by asking the patient about his or her current level of pain, rather than asking the patient to speculate about “usual” or “previous” levels of pain.10   CLINICAL TIP The therapist should be sensitive to, and respectful of, how different cultures perceive pain, as pain expression may vary among cultures.5,11 The therapist should be aware that some physiologic indicators exist normally in critically ill patients One needs to analyze the behavioral trend and differentiate pain from physiologic changes.12 The Adult Nonverbal Pain Scale is targeted toward adult patients who are intubated and sedated and is adapted from the FLACC Pain Assessment Tool.12 The Behavioral Pain Scale (BPS) is used for mechanically ventilated, sedated patients in the intensive care unit (ICU).4 Validity measured by BPS scores increase with painful stimuli.13 Good construct validity (p < 0.001) has been reported for the FLACC as evidenced by decreased pain scores after administration of analgesics and from painful to nonpainful situations The FLACC has also demonstrated good interrater reliability when assessing pain in critically ill patients.14 This was consistent when compared among use with adults, children, and patients who are mechanically ventilated However, there is some disagreement concerning the use of this scale with adults because of their inability to CHAPTER 21    Acute Pain Management demonstrate some behaviors associated with the pediatric population Those who disagree suggest utilizing the NVPS, as it has good interrater reliability and validity with critically ill, sedated, mechanically ventilated, and/or cognitively impaired adults.12,14,15 The CPOT was developed to assess pain in critically ill ICU patients and was mainly used with those recovering from cardiac surgery It is reliable and valid in this population and further research is required for its use in other populations.16 The CPOT can be used with both verbal and nonverbal patients.4,16 Physical Therapy Considerations for Pain Evaluation • Observe pain-related behaviors to appropriately select an assessment tool Use nonverbal assessment tools when selfreport is unattainable.5 • Select the appropriate tool based on the clinical environment and relevance to the specific patient population.5 TABLE 21-3  Behavioral Pain Scale Item Description Facial expressions Relaxed Partially tightened (e.g., brow lowering) Fully tightened (e.g., eyelid closing) Grimacing No movement Partially bent Fully bent with finger flexion Permanently retracted Tolerating movement Coughing but tolerating ventilation for most of the time Fighting ventilator Unable to control ventilation Movements of upper limbs Compliance with ventilation Score 4 459 • Table 21-6 provides a comparison of the various pain scales to aid in selecting an appropriate tool The VAS and NRS tend to be used commonly in the clinical setting.5,17 • Patients report a preference for the NRS because of its ease of use and accuracy • In consideration of Joint Commission requirements, each patient interaction needs a pain rating, even if the patient reports 0/10 on the NRS • A pain grade is generally accompanied by location, description, and most importantly, an “intervention,” especially if pain is graded greater than 4/10 on the NRS • The physical therapist should recognize when the patient is weaning from pain medication (e.g., transitioning from intravenous to oral administration), as the patient may complain of increased pain with a concurrent reduced activity tolerance during this time period • To optimize consistency in the health care team, the physical therapist should use the same pain rating tool as the medicalsurgical team to determine adequacy of pain management • Often the best way to communicate the adequacy of a patient’s pain management to the nurses or physicians is in terms of the patient’s ability to complete a given task or activity (e.g., the patient is effectively coughing and clearing secretions) Therapists should communicate both verbally and in written form to the medical team if the pain management is insufficient to allow the patient to accomplish functional tasks Pain Management From Payen JF, Bru O, Bosson JL et al: Assessing pain in critically ill sedated patients by using a behavioral pain scale, Crit Care Med 29(12):2258-2263, 2001 The primary goal in acute pain management is to promote the resolution of the underlying causes of pain while providing effective analgesia.18 Acute pain can be managed using both pharmacologic and nonpharmacologic techniques (including physical therapy) either in isolation or more often in combination.19,20 This section focuses on pharmacologic management while the next section will describe physical therapy management considerations TABLE 21-4  FLACC Pain Assessment Tool Categories Score = Score = Score = Face No particular expression or smile Legs Activity Frequent to constant frown, clenched jaw, quivering chin Kicking, or legs drawn up Arched, rigid, or jerking Cry Normal position or relaxed Lying quietly, normal position, moves easily No cry (awake or asleep) Consolability Content, relaxed Occasional grimace or frown, withdrawn, disinterested Uneasy, restless, tense Squirming, shifting back/forth, tense Moans or whimpers, occasional complaint Reassured by occasional touching, hugging, or “talking to,” distractible Crying steadily, screams or sobs, frequent complaints Difficult to console or comfort Indication: For nonverbal patients, particularly the pediatric population From

from Gélinas C: Nurses’ evaluations of the feasibility and the clinical utility of the Critical-Care Pain Observation Tool, Pain Manag Nurs 11(2):115-125, 2010   CLINICAL TIP Communication among therapists, nurses, physicians, and patients on the effectiveness of pain management is essential to maximize the patient’s comfort This includes a thorough review of the patient’s medical history and the doctor’s orders by the physical therapist before prescribing any modalities or therapeutic exercises Pharmacologic management of acute pain is based on the World Health Organizations (WHO) Analgesic Ladder21,22 originally designed to promote ongoing assessment of pain management during the palliative care of patients with cancer.20 The WHO ladder is a stepwise process in which step is for patients with mild pain in whom the use of nonopioid analgesia is recommended, step is for moderate pain and advocates the use of weak opioids with or without nonopioids, and step is for patients with severe pain in whom strong opioids with or without nonopioids are recommended.20 Table 21-7 provides an overview of commonly utilized opioid agents in the management of acute pain Nonopioid drugs typically comprise nonsteroidal antiinflammatory drugs (NSAIDs) (Table 21-8) and acetaminophen (paracetamol), which is a centrally acting analgesic that interacts with the cyclooxygenase system.18,19 Acetaminophen also has antipyretic effects and is an effective analgesic when used alone or as an adjunct to opioid analgesia.18 As a group, NSAIDs are nonselective cyclooxygenase inhibitors Cyclooxygenase (COX) is an enzyme that exists in two forms (COX-1 and COX-2).23 The homeostatic pathways, which include production of prostaglandins and thromboxane, primarily involve the COX-1 enzyme, while COX-2 is involved with pathways that produce pain and inflammation Prostaglandins have a protective role for the mucosal lining of the gastrointestinal tract; therefore nonselective inhibition of these substances can result in gastrointestinal (GI) dysfunction (see Chapter 8) Selective inhibition of COX-2 was found to decrease injury to the mucosal lining of the stomach, leading to the development of COX-2 selective agents, which were aimed at reducing inflammation without adverse GI effects Unfortunately, these agents were also correlated with an increased risk of cardiovascular events in susceptible individuals, resulting in agents such as rofecoxib (Vioxx) and valdecoxib (Bextra) being taken off the market Currently celecoxib (Celebrex) is the only COX-2 selective agent still available.23,24 Careful patient selection regarding all NSAIDs and overall cardiovascular risk need to be considered.23 Acetylsalicylic acid (aspirin) is the oldest form of NSAID prescribed for patients to help manage pain and inflammation, as well as providing antiplatelet effects for vascular conditions.23 Opioid agents and NSAIDs can be administered by oral, intravenous, or intramuscular routes Alternative routes of administration for pain medications include local anesthetics (Tables 21-9A and 21-9B) and patient-controlled analgesia (PCA) (Table 21-10) 461 CHAPTER 21

rehabilitation, ed 4, Philadelphia, 2007, FA Davis, pp 149-160 Physical Therapy Considerations for Pain Management • The physical therapist should be aware of the patient’s pain medication schedule and the duration of the effectiveness of different pain medications when scheduling treatment sessions, particularly if premedication is necessary to optimize intervention • Patients should be educated on the need to request pain medicine or push their PCA button when they need it, particularly when they are on an “as needed” (PRN) pain medication schedule.25 • Patients should be asked about the specific type of pain that the medication is intended for, such as postsurgical incisional pain Pain medications, such as opioids, may mask the occurrence of a new type of pain, such as angina.25 • The physical therapist should also use a pillow, blanket, or his or her hands to splint or support a painful area, such as an abdominal or thoracic incision or rib fractures, when the patient coughs or performs functional mobility tasks, such as going from a sidelying position to sitting at the edge of the bed.26 • The physical therapist can also use a corset, binder, or brace to support a painful area during intervention sessions that focus on functional mobility • Patients may experience pain induced by exercise or mobilization (PIEM), which can be perceived by patients as a decreased quality of life and result in fears about participation in physical therapy and refusal of care Enhanced communication among care providers and with the patient about expected pain responses during therapy may lessen the adverse results of PIEM.27   CLINICAL TIP Patients, particularly those who are postsurgical, are often prescribed more than one type of pain medication in order to achieve “breakthrough” pain levels In other words, they require additional medicine to break their pain 464 CHAPTER 21    Acute Pain Management TABLE 21-10  Patient-Controlled Analgesia Indications Side effects Medications For patients with moderate to severe acute pain who are not cognitively impaired and are capable of properly using the pump Preoperative education of the patient on the use of patient-controlled analgesia Ensuring that only the patient doses himself or herself Dosage, dosage intervals, maximum dosage per set time, and background (basal) infusion rate can be programmed Pump apparatus, tubing and power lines could limit mobility Similar to those of opioids (see Table 21-7) Morphine, meperidine, fentanyl, and hydromorphone Types Description Intravenous patient-controlled analgesia (IV PCA) Patient-controlled epidural analgesia (PCEA) An intravenous line to a peripheral vein is connected to a microprocessor pump, and a patient is provided a button to allow self-dosing The tip of a small catheter is placed in either the epidural or the subarachnoid space and connected to a pump For short-term use, the catheter exits through the back to connect to a pump For long-term use, the catheter is tunneled through the subcutaneous tissue and exits through the front for patient control The catheter tip is inserted directly into a specific anatomic site such as a wound (incisional PCRA), near a peripheral nerve (perineural PCRA), or into a peripheral joint (intra-articular [IA] PCRA) The other end of the catheter is attached to a pump with a button for patient control Ropivacaine and bupivacaine are also used in PCRA Intranasal opioids are delivered using a syringe, nasal spray or dropper, or nebulized inhaler either in dry powder or water or saline solution A pump mechanism is adapted to provide PCINA A needle-free, self-contained fentanyl delivery system that does not require venous access for administration System adheres to outer arm or chest with an adhesive backing and, via iontophoresis, delivers fentanyl across intact skin Patient has on-demand dosing up to doses/hour Considerations Patient-controlled regional analgesia (PCRA)
