o Shock

18
- Genitourinary clinical manifestations of pain (4)
o Decreased urine output o Urinary retention o Fluid overload o Hypokalemia
19
- Sensory clinical manifestations of pain (6)
o Pallor o Diaphoresis o Dilated pupils in acute pain o Constricted pupils in deep or prolonged pain o Rapid speech in acute pain o Slow speech in deep or prolonged pain
20
- Immune clinical manifestations of pain (2)
o Impaired immune function o infection
21
- Cues or behaviors in response to pain
o grimaces o clenched teeth o rubbing or guarding of the painful area o agitation o restlessness o withdrawal from painful stimuli
22
- Vocalizations of pain
o Crying o Moaning o Screaming
23
- Behaviors of a patient in labor in response to pain
o Effleurage (rhythmic massaging of the abdomen with her hands o Immobilization to help deal with uterine contraction pain.
24
- Complementary and alternative pain therapies
- recommended for patients with mild pain who do not want to use medications to control pain o Herbal remedies o Yoga o Biofeedback o Mediation o Aromatherapy o Hypnosis o Reiki and therapeutic touch o Traditional Chinese medicine  Acupuncture  Acupressure  Cupping
24
NSAID and non opioid analgesics
- Non-opioid: include acetaminophen NSAIDS (Motrin and aspirin). Used to treat mild pain. Non addictive and safer. o Acetaminophen: long term use may result in hepatotoxicity or renal disease. Daily dose of 3000mg should not be exceeded. An OD can be fatal o NSAIDS: have significant side effects (GI upset and bleeding, cardiac and renal complications). Can avoid symptoms by taking meds with food.
25
- Patient-controlled analgesia (PCA)
system in which an infusion pump immediately delivers medication to the patient when they push a button without the need for the nurse. o Used more frequently but in smaller doses. o Delivered:  IV  SubQ  Epidurally o LEGALLY only the patient can push the button to give themselves the pain injection
26
- On-Q pump
continuous infusion of local anesthesia through an antimicrobial catheter o Used for post op pain after abdominal surgery
27
- Transdermal patch:
consists of a medicated adhesive patch that is placed on the skin to deliver a specific dose of medication through the skin allowing for absorption into the blood stream
28
- Intrathecal injection
: into the subarachnoid spaice through a needle or a catheter to provide relief of pain to a large area of the body o Spinal anesthesia for surgery
29
- Epidural anesthesia
continuous infusion of a narcotic or local anesthetic into the epidural space by a needle (used for labor pain, surgery, cancer pain)
30
- Nerve block
injection of local anesthetic into or near spinal nerves for temporary pain control o Used for migraines o Headaches o Dental work o Back pain o Herniated disks o Cancer pain
31
- Physical dependence
builds as the body becomes unable to function normally without the medication, reaching the point of withdrawal symptoms on abrupt cessation of the medication.
31
- Drug tolerance
an adaptation to medication which eventually leads to be less effective o Better to change to a new medication instead of increasing dose.
32
- Addiction
psychological or emotional dependence on a prescribed medication or illicit drug. You crave the drug and engage in compulsive use or abuse regardless of consequences
33
- Opioid analgesics
the most effective agents for relief of moderate to severe pain.  Agonist analgesics  Agonist antagonist analgesics  Antagonist analgesics
34
o Agonist analgesics:
: they change the patients perception of pain while relieving the pain; most effective agents for relief of severe pain rated 7-10 on a NRS;  Drugs: * Morphine * Hydromorphone * Oxycodone * Fentanyl * Meperidine  Routes: * Oral * Transdermal * IM may be given q1-3 * IV may be given q1-3  Adverse effects: * Respiratory depression * Seizures * Nausea * Vomiting * Constipation * Itching * Urinary retention * Dizziness * Blurred vision * Confusion * Orthostatic hypotension
34
o Agonist-antagonist analgesics
they depress the pain-impulse transmission at the spinal cord by acting with opioid receptors; used for moderate to severe pain  Drugs * Pentazocine * Butorphanol * Dezocine * Nalbuphine  Routes: * IM; q1-4 depending on drug * IV; q1-4 depending on drug  Adverse effects: * Drowsiness * Dizziness * Nausea * Vomiting * Itching * Respiratory depression
35
- Adjuvant or Co-analgesic medications:
: work synergistically with standard pain medications to enhance pain relief and treat side effects of the medication. o Examples:  Antidepressants and anticonvulsants may be used together to treat neuropathic pain  Antiemetics given with opioids to counteract N/V  Laxatives given with opioids to help reduce constipation * senna or docusate  antihistamines to decrease the itching side effect of opioids  Ketorolac (Toradol) and NSAID) given with opioids to enhance pain relief  Caffeine used with analgesics to treat migraines.
35
o Antagonist analgesics
used for treatment of opioid analgesic overdose; competes with the opioid receptor sites, decreasing the side effects of opioids.  Drugs: * Naloxone  Routes: give q2-3min until symptoms of opioid overdose subside * IV * IM * Sub Q * Endotracheal tube  Withdrawal symptoms * May occur up to 2 hours after administration o Vomiting o Hypertension o anxiety
35
- Multimodal:
: provides holistic pain management by including nonpharmacological interventions, nonopioid analgesics, opioid analgesics and coanalgesics (meds that were not primarily for pain relief but work in conjunction with opioids to optimize outocme
