28
Q

local Anesthesia: Nursing Considerations

A
  • Observe for a systemic toxic reaction due to CNS stimulation (headache, blurred vision, metallic taste).
  • Without treatment, it leads to unconsciousness, hypotension, apnea, cardiac arrest, and death.
  • Establish airway patency, administer oxygen, and monitor oxygen saturation. Then notify the anesthesiologist and surgeon.
  • Monitor the client following administration of a fast-acting barbiturate.
  • Monitor and report laboratory values (ABGs, CBC, and electrolytes).
  • Monitor cardiac status (rhythm, heart rate, blood pressure).
  • Monitor drains, tubes, catheters, and IV access throughout anesthesia and surgery
29
Q

what should you assess after giving a local anesthesia

A
  • Assess motor function to ensure paralysis does not ensue (sense of touch returns first followed by pain, warmth, cold, and finally the ability to move).
  • With epidural and spinal anesthesia, monitor for autonomic nervous system blockade (hypotension, bradycardia, nausea, vomiting).
  • Lower the head of the bed, increase IV fluid infusion rate if no restrictions, and monitor vital signs.
30
Q

csfk leakage w local anesthesia

A
  • CSF leakage (spinal and epidural) manifests with a severe headache when the head of the bed is elevated.
  • Keep the head of the bed flat to promote the dura tear to seal.
  • Provide a quiet environment.
  • Keep the client well hydrated to help replace CSF loss.
31
Q

whos responsible for transfer from post ip to pacu

A
  • responsibility of the anesthesia provider: an anesthesiologist or certified registered nurse anesthetist.
  • The circulating nurse will give the verbal hand‑off report to the PACU nurse.
32
Q

where is post op care provided

A
  • Postoperative care is usually provided initially in the PACU, where skilled nurses who are certified in advanced cardiac life support can monitor a client’s recovery from anesthesia.
  • In some instances, a client is transferred from the operating suite directly to the intensive care unit
33
Q

initial post op care involves

A
  • Assessments
  • Administering medications
  • Managing pain
  • Preventing complications
  • Determining when a patient is ready to be discharged from the PACU
  • bleeding usually happens within 2hr after pacu
34
Q

priority During the immediate postoperative stage

A

*****maintaining airway patency and ventilation and monitoring circulatory status are the priorities
- Postoperative patients who receive general anesthesia require frequent assessment of their respiratory status.

  1. A client who has a WBC of 22,500/uL
  2. A client who uses an insulin pump
  3. A client who takes warfarin daily
  4. A client who has heart failure
  5. A client who has a BMI of 26
A

1-4

48
Q

assessment: airway

A
  • An artificial airway (endotracheal tube, nasal trumpet, or oral airway) is left in place until a client can maintain an open airway without support.
  • Assess blood oxygen saturation levels continuously (Sat probe)
    Should be greater than 95% or at preoperative baseline.
  • Assess respiratory pattern, rate, and depth to determine adequacy of oxygen exchange
  • Assess for symmetry of breath sounds and chest wall movement.
  • Absent breath sounds on the left can indicate the endotracheal tube has migrated down the right mainstem bronchus or that there is a pneumothorax.
  • Auscultate lung sounds.
  • Administer humidified oxygen.
  • Suction accumulated secretions if the patient is unable to cough
    Snoring or stridor:
  • A high-pitched crowing type sound
  • Can indicate poor oxygen exchange.
49
Q

suction

A

Use a Yankauer suction for thick oral secretions or a large French suction catheter for nasopharyngeal or nasotracheal secretions.

50
Q

when to take airway out

A
  • Retained neuromuscular blocking agents can hinder the client’s ability to cough and eliminate secretions.
  • Extubation(removal) of endotracheal tube is based on client’s response to commands, ability to elevate head, and use of thoracic breathing.
    -As soon as the patient follows commands, encourage coughing, deep breathing, and use of the incentive spirometer
51
Q

circulation: s/s of internal bleeding

A
  • Abdominal distension
  • Visible hematoma under/near the surgical site
