Narcotic AnalgesicsNursing Process

• Assessment

– Pain assessment– Precipitating factors– Nonpharmacological medications– Time last medicated– Response to last pain medication– Allergies– Bowel history

Narcotic AnalgesicsNursing Process

• Planning

– Adverse reactions– Expected pain relief– Route of administration

Narcotic AnalgesicsNursing Process

• Suggested Nursing Diagnoses

– Pain, acute– Pain, chronic– Constipation r/t adverse drug effects

Narcotic AnalgesicsNursing Process

• Implementation

– Identify patient– Observe 6 Rights

Narcotic AnalgesicsNursing Process

• Evaluation

– Response to medication– Evidence of adverse reactions– Evidence of tolerance, addiction

Narcotic AnalgesicsKey Points

• Side Effects– Lethargy, Confusion– Constipation

• Adverse Reactions– Respiratory Depression (Opiate Naïve)– Opiate Poisoning

• Combination Drugs– Be mindful of acetaminophen toxicity

Narcotic AnalgesicsKey Points

• Addiction– Not likely to happen when purpose of drug is to

relieve pain

• Tolerance– Likely to occur, especially with morphine

• PCA’s– PCA’s are PATIENT controlled, not nurse

controlled

Narcotic AnalgesicsKey Points

• Opioids are drugs of choice for SOME pains

• Not ALL pain should be managed with Opioids

• Review: Thumbs Up? Thumbs Down?

Narcotic AnalgesicsKey Points

• Pain associated with Myocardial Infarction– Morphine is the drug of choice

Narcotic AnalgesicsKey Points

• Pain associated with Ulcerative Colitis– Opioids should be avoided

Narcotic AnalgesicsKey Points

• Pain associated with Gall Bladder surgery– Avoid morphine– Meperidine is drug of choice

Narcotic AnalgesicsKey Points

• Pain associated with Labor– May prolong labor– May cause respiratory depression in the

newborn

Narcotic AnalgesicsKey Points

• Pain associated head injury– Opioids may increase intracranial pressure

(ICP)

Narcotic AnalgesicsKey Points

• Pain in patients with COPD– Opioids cause respiratory depression

Narcotic AnalgesicsKey Points

• Pain in patients with seizure disorders– Opioids may precipitate seizures

Anesthestic Medications

Anesthetic Medications

• Topical

– Application to body surface– Cream, lotion, spray, gel, etc.– May be given prior to an

injection

Anesthetic Medications

• Local Infiltration

– Injection of anesthetic into tissue– Example: Novacaine

Anesthetic Medications

• Regional Anesthesia

– Spinal

Subarachnoid space

– Conduction

Near a nerve

Anesthetic Medications

• Regional Anesthesia - Spinal

– Injected into subarachnoid space of spinal cord– Most commonly 2nd lumbar vertebra– Loss of feeling and movement• Lower abdomen

• Perineum

• Lower extremities

Anesthetic Medications

• Regional Anesthesia – Conduction Blocks

– Epidural block– Caudal block

– Brachial plexus block

Anesthetic Medications

• Preparing the patient for local or regional anesthetics– Positioning– Teaching– Emotional Support

Anesthetic Medications

• Providing care after local or regional anesthesia– Safety r/t lack of sensation– Loss of body functions– Hemorrhage– Infection

Anesthetic Medications

• Preanesthesia Medications

– Opioids to decrease anxiety / apprehension• Fentanyl (Sublimaze)

• Meperidine (Demerol)

• Morphine

Anesthetic Medications

• Preanesthesia Medications

– Barbiturates to decrease anxiety / apprehension• Pentobarbital (Nembutal)

• Secobarbital (Seconal)

Anesthetic Medications

• Preanesthesia Medications

– Benzodiazepines to decrease anxiety / apprehension• Chlordiazepoxide (Librium)

• Diazepam (Valium)

• Midazolam (Versed)

• Lorazepam (Ativan)

Anesthetic Medications

• Antiemetic Medications

– Decrease nausea / vomiting and side effect of drowsiness / antianxiety• Hydroxizine (Vistaril)

• Promethazine (Phenergan)

Anesthetic Medications

• Antiemetic Medications

– Cholinergic blocking agents to decrease respiratory secretions and mucous production• Atropine sulfate

• Robinul

• Scopolamine

Anesthetic Medications

• General Anesthesia

– Cause loss of consciousness– Except for very short procedures, patient must

be intubated– Profound analgesia

Anesthetic Medications

• Types of General Anesthesia

– Barbiturates• Methotrexital (Brevital)

• Propofol (Diprivan)

Anesthetic Medications

• Types of General Anesthesia

– Benzodiazepines• Midazolam (Versed)

Anesthetic Medications

• Types of General Anesthesia

– Ketamine (Ketalar)

• Street Drug

Special K

Anesthetic Medications

• Types of General Anesthesia

– Gases and Volatile Liquids• Nitrous oxide

Anesthetic Medications

• Types of General Anesthesia

– Opioids• Fentanyl (Sublimaze)

• Given as adjunct to other medications to produce reduced motor activity and profound analgesia

Anesthetic Medications

• Types of General Anesthesia

– Skeletal Muscle Relaxants• Deep abdominal or chest surgery

• Facilitate endotracheal insertion

• Succinylcholine (Anectine)

Anesthetic Medications

• 4 Stages of Anesthesia

– Stage 1 – Analgesia– Medication given to induce anesthesia– Lasts 5 – 10 seconds

Anesthetic Medications

• 4 Stages of Anesthesia

– Stage 2 – Delerium– Delerium– Keep room quiet

Anesthetic Medications

• 4 Stages of Anesthesia

– Stage 3 – Surgical Analgesia– Deep coma– Surgery takes place

Anesthetic Medications

• 4 Stages of Anesthesia

– Stage 4 – Respiratory Paralysis– ABNORMAL – Severe Complication– Respiratory and Cardiac Arrest

Anesthetic Medications

• Nursing Responsibilities

• Administer Pre-op medications observing 5 rights

• Provide safety after medications given

Anesthetic Medications

• Nursing Responsibilities

– Post Anesthesia: PACU• Check airway for patency

• Observe for hypoxia, especially if nitrous oxide administered

• Position patient to prevent aspiration

• Check patient every 5 – 10 minutes, suctioning as needed

Anesthetic Medications

• Nursing Responsibilities

– Post Anesthesia: PACU (cont.)• Exercise caution in administering opioids

• Record all medications given

Anesthetic Medications

• Nursing Responsibilities

– Post Anesthesia: Post-op• Continue to exercise caution with opioid medications

• Refrain from barbiturates and benzodiazepines during first 24 hours

• Administer supplemental oxygen as needed

Anesthesia MedicationsKey Points

• Anesthesia can be– Local– Regional– General

Anesthesia MedicationsKey Points

• Many different kinds of medications can induce anesthesia– Barbiturates (Nembutal, Seconal)– Benzodiazepines (Versed)– Ketamine– Nitrous oxide– Opioids (Inapsine)– Skeletal muscle relaxants (Anectine)

Anesthesia MedicationsKey Points

Anesthesia MedicationsKey Points

• Nursing Responsibilities are dependent upon type of anesthesia given, but always focus on– Airway (respiratory depression, aspiration)– Safety (confusion, lethargy)– Comfort (without reentering anesthesia state)
