Intra-op definition
Begins when the pt is received in the OR and ends with admission to post anesthesia recovery room (PARR).
-

- Anestheiologist - can be MD or nurse, starts IV, central line
- Perioperative staff - RN, scrub tech, support staff, instrument personnel
-

Holding Nurse
Does all checks & balances
-

-
Roles in the OR
Specialty Nurse
Educated for a particular type of surgery
-
Roles in the OR
Laser-light amplification by the stimulated emission of radiation
High power beam of light that cuts thru tissue - intense heat. Must wear eye protectors.
-
Surgical Area Preparation
- Layout of suite
- Electrical safety
- Health of team
- Attire/scub
- Surgical awareness
-
Surgical Asepsis
- Hand washing - surgical scrub - wash for 2 minutes for everyone who goes in
- Droplet contamination - sneeze in sleeve
- Avoid spilling
- Open packages correctly - look to see where to peel
- Sterile items
- Clothing - scrubs, shoes kept in OR if working there
-
General surgical considerations
- Team meets with patient
- Anesthesiologist makes an assessment
- RN makes assessment & documents the intraoperative NCP
-
Anesthetic Techniques
- General - reversible state - pt loses consciousness as a result of inhibition of neural impulses in several areas of the CNS
- Analgesia - pain relief
- Amnesia - memory loss of surgery
-
Four Stages of Anesthesia
Stage 1
Analgesia & sedation, relaxation
Begins with induction & ends with loss of consciousness. Pt feels drowsy & dizzy. Hearing is exaggerated.
Nursing interventions - close OR door, dim lights, control traffic, position pt securely with safety belts,
Rationales - avoids external stimuli & promotes relaxation
-
Four Stages of Anesthesia
Stage 2
Excitement, delirium
Begins with loss of consciousness & ends with relaxation & loss of eyelid reflux. May have irregular breathing, increased muscle tone & involuntary movements. Laryngospasm or vomiting may occur.
Nursing Interventions - Stay with pt & protect. Avoid auditory & physical stimuli.
Rationales - staying with pt is emotionally supportive & safety measures help to prevent injury
-
Four Stages of Anesthesia
Stage 3
Operative anesthesia, surgical anesthesia
Begins with generalized muscle relaxation & ends with loss of reflexes & depression of vital functions. Jaw is relaxed & there is quit, regular breathing. Pt cannot hear. Sensations are lost.
Nursing Interventions - assist anesthesiologist with intubation. Place into operative position. Prep the operative site as directed.
Rationales - providing assistance helps promoste smooth intubation & prevent injury. Performing procedures asap promotes time management to minimize total anesthesi time for pt.
-
Four Stages of Anesthesia
Stage 4
DANGER
Begins with depression of vital functions & ends with respiratory failure, cardiac arrest, & possible death. Pupils are fixed & dilated. Respiratory muscles are paralyzed; apnea occurs.
Nursing Interventions - prepares for & assists in treatment of cardiac/pulmonary arrest. Document occurrence.
-
General Anesthesia
- Inhalation
- Gaseous agents - nitrous oxide
- Endotracheal tube
- Intravenous - barbiturates
- Balanced - combination inhaled/intravenous
- Adjuncts - opioids/neuromusc. blocking agents
-
Complications of general anesthesia
- Sore throat
- Overdose
- Unrecognized hypoventilation
- Complications of intubation - knock out tooth, vocal cords injury...
- Malignant hyperthermia
-
Malignant Hyperthermia
- Inherited disorder resulting in chemical reaction causing an increased metabolic rate
- Deficit in cell membrane - increased circulating calcium level
- S/S - muscles get rigid, increased HR, arrythmias, coke-colored urine related to muscle contraction, skin-mottled, increased temp (111 F)
- Death, renal failure
- TX - dantrolene sodium (Dantrium), cooling measures, fluids
-
Local Anesthesia
Local/Topical - agents applied directly to skin
Local infiltration - injection of an agent directly into tissue around an incision, wound, or lesion. Used for suturing.
-
Regional Anesthesia
May be used when general anesthesia cannot be used because of a disease, pt has had reaction to general anesthesia, pt's choice, or pain management is enhanced by regional anesthesia -- still have gag reflex.
-
Regional Anesthesia
Field Block
Occurs with a series of injections around the operative field. Used for chest procedures, hernia repairs, dental surgery & some plastic surgeries.
-
Regional Anesthesia
Nerve Block
Occurs with injection of local anesthetic agent into or around a nerve or group of nerves. Used for example after rotator cuff repair.
-
Regional Anesthesia
Spinal Anesthesia
AKA intrathecal block. Occurs by injecting an anesthetic agent into cerebrospinal fluid in subarachnoid space. It is used for lower abdominal & pelveic surgery.
-
Regional Anesthesia
Epidural Anesthesia
Injected into epidural space & spinal cord areas are never entered. Use for vaginal, hip & lower extremity surgeries. Two advantages are decreased cardiac & pulmonary complications which are especially important for older pt & use of epidural catheter for pain control after surgery.
-
Complications of Local or Regional Anesthesia
- Incorrect placement or delivery technique
- Nurse assesses for CNS stimulation followed by CNS & cardiac depression which are signs of a system toxic reaction.
- Nurse observes for blurred vision, H/A, incoherent speech, metallic taste, N/V, siezures, & an increase in vital signs.
- If untreated, death may occur.
Interventions - establish an airway, giving oxygen, notify surgeon
-
Conscious Sedation
Administration of sedative, hypnotic, & opiod meds to produce a condition in which the pt has a depressed level of consciousness but retains ability to independently maintain a patent airway & respond appropriately to verbal commands & physical stimulation
Versed (midazolam), Valium
-
Presurgical Assessment
- Name
- Chart
- Pre-op checklist
- Informed consent
- Allergies
- Labs
- Hx/physical
- Autologous blood transfusion
-
Nursing diagnoses
- R/F infection R/T break in skin integrity
- R/F disuse syndrome R/T immobilization
- Ineffective thermoregulation R/T medications
- R/F injury
-
Client Safety / Interventions
- Staff health
- Pause
- Traffic
- Draping
- Grounding
- Positioning - pad under bony prominances, maintain good alignment
- Interventions - skin prep night before, wound closure (staples, absorbable, non), documenting
- To PARR - anesthesiologist & circulating nurse accompany pt
