Pain: The Fifth Vital Sign
Definitions of Pain
 Pain is an unpleasant sensory and emotional experience
associated with actual or potential tissue damage.
 Pain is whatever the experiencing person says it is and exists
whenever he or she says it does (McCaffery, 1999).
 Self-report is always the most reliable indication of pain.
Types of Pain
 Types of pain:
 Acute pain
 Chronic pain:
 Chronic cancer pain
 Chronic non-cancer pain
 Sources of pain:
 Nociceptive pain types:
 Somatic pain
 Visceral pain
 Neuropathic pain
Pain Transmission
Attitudes and Practices Related to
Pain
 Attitudes of health care providers and nurses affect
interaction with patients experiencing pain.
 Many patients are reluctant to report pain:
 Desire to be a “good” patient
 Fear of addiction
Addiction, Pseudoaddiction, Tolerance,
and Physical Dependence
 Addiction—primary, chronic neurobiologic disease with
genetic, psychosocial, and environmental factors influencing
its development and manifestations
 Pseudoaddiction—iatrogenic syndrome created by the
undertreatment of pain
 Tolerance—state of adaptation in which exposure to a drug
results in a decrease in one or more the drug’s effects over
time
Addiction, Pseudoaddiction, Tolerance, and
Physical Dependence (Cont’d)
 Physical dependence—adaptation manifested by a drug-class–
specific withdrawal syndrome that can be produced by abrupt
cessation, rapid dose reduction, decreasing blood level of the drug,
and/or administration of an antagonist
 Withdrawal or abstinence syndrome—N&V, abdominal cramping,
muscle twitching, profuse perspiration, delirium, and convulsions
Collaborative Management
 History
 Physical assessment/clinical manifestations:
 Location of pain:
 Localized pain
 Projected pain
 Radiating pain
 Referred pain
Pain Pharmacologic Therapy—
Non-Opioid Analgesics
 Acetylsalicylic acid (aspirin) and acetaminophen (Tylenol) are
most common
 Most are NSAIDs, including aspirin:
 Can cause GI disturbances
 COX-2 inhibitors for long-term use
Non-Opioid Analgesics (Cont’d)
 Acetaminophen (Tylenol):
 Available in liquid form; can be taken on empty stomach
 Preferable for patients for whom GI bleeding is likely
 Can cause renal or liver toxicity if used long-term
Pain Pharmacologic Therapy—
Opioid Analgesics
 Block the release of neurotransmitters in the spinal cord
 Drugs include codeine, oxycodone, morphine,
hydromorphone, fentanyl, methadone, tramadol,
meperidine, oxymorphone
Side Effects of Opioids



Nausea and vomiting
Constipation
Sedation
Respiratory depression
WHO Analgesic Ladder
 World Health Organization’s recommended guidelines for
prescribing, based on level of pain (1-10, 10 is most severe
pain)
 Level 1 pain (1-3 rating)—Use non-opioids
 Level 2 pain (4-6 rating)—Use weak opioids alone or in
combination with an adjuvant drug
 Level 3 pain (7-10 rating)—Use strong opioids
Pain Management in End of Life
 Opioid regimen should stay consistent with dose in weeks
before last weeks of life
 Generally believed that patient still feels pain when
unconscious
 Does not hasten death unless the dose was not properly and
gradually titrated
Routes of Opioid Administration
 Can be administered by every route used
 PRN range orders
 Patient-controlled analgesia (PCA)
PCA Infusion Pump
Spinal Analgesia
 Epidural analgesia
 Intrathecal (subarachnoid) analgesia

Deficient Knowledge Interventions
 Preoperative teaching.
 Informed consent:
 Surgeon is responsible for obtaining signed consent before
sedation and/or surgery.
 The nurse’s role is to clarify facts presented by the physician
and dispel myths that the patient or family may have about
surgery.
Implementing Dietary Restrictions
 NPO: Patient advised not to ingest anything by mouth for 6
to 8 hours before surgery:
 Decreases the risk for aspiration.
 Patients should be given written and oral directions to stress
adherence.
 Surgery can be cancelled if not followed.
Administering Regularly Scheduled
Medications
 Medical physician and anesthesia provider should be
consulted for instructions about regularly taken
prescriptions before surgery.
 Drugs for certain conditions often allowed with a sip of
water before surgery:




Cardiac disease
Respiratory disease
Seizures
Hypertension
Intestinal Preparation
 Bowel or intestinal preparations performed to prevent
injury to the colon and to reduce the number of intestinal
bacteria.
 Enema or laxative may be ordered by the physician.
Skin Preparation
 A break in the skin increases risk for infection.
 Patient may be asked to shower using antiseptic solution.

Anesthesia
 Induced state of partial or total loss of sensation, occurring
with or without loss of consciousness
 Used to block nerve impulse transmission, suppress reflexes,
promote muscle relaxation, and, in some cases, achieve a
controlled level of unconsciousness
General Anesthesia
 Reversible loss of consciousness induced by inhibiting
neuronal impulses in several areas of the central nervous
system
 Involves a single agent or a combination of agents
Four Stages of General Anesthesia



Stage 1—analgesia and sedation, relaxation
Stage 2—excitement, delirium
Stage 3—operative anesthesia, surgical anesthesia

Conscious Sedation
 IV delivery of sedative, hypnotic, and opioid drugs to
reduce the level of consciousness.
 Patient maintains a patent airway and can respond to
verbal commands.
 Amnesia action is short with rapid return to ADLs.
