Study Notes

Malignant Hyperthermia

  • Malignant hyperthermia: a life-threatening medical emergency
  • Induction of general anesthesia: drowsy, dizzy, exaggerated pain sensation, decreased consciousness
  • Loss of consciousness: relaxation, light hypnosis, loss of consciousness, increased muscle tone
  • Regular pattern of respiration: total paralysis of intercostal muscles, cessation of voluntary respiration
  • Danger stage: respiratory failure, possible cardiac arrest, prepare for cardiopulmonary resuscitation

Regional Anesthesia

  • Production of anesthesia in a specific body part
  • Injecting local anesthetics in close proximity to appropriate nerves
  • Spinal Anesthesia: local anesthetic injected into lumbar intrathecal space/subarachnoid space
  • Spinal anesthesia produces excellent analgesia and relaxation for abdominal and pelvic procedures
  • Epidural Anesthesia: local anesthetic injected into epidural space via lumbar puncture
  • Peripheral Nerve Blocks: anesthetic injected around a nerve supplying sensation to a small area
  • Intravenous Block: local agent injected into a vein with an occlusion tourniquet
  • Local Anesthesia (Infiltration): agent injected into surgical site for minor and superficial procedures
  • Topical Anesthesia: anesthetic agent applied directly to skin and mucous membranes

Complications of Spinal Anesthesia

  • Hypotension
  • Nausea and vomiting
  • Urinary retention
  • Post-spinal headache

Positioning Surgical Patient

  • 5 factors to consider: anatomy involved, surgical approach, patient comfort, patient and staff safety, respiratory and circulatory freedom
  • Supine (Dorsal Recumbent): abdominal, extremity, vascular, chest, neck, and facial procedures
  • Lateral Recumbent: chest and kidney procedures
  • Trendelenburg: lower abdominal and pelvic organ procedures
  • Kraske (Jacknife): rectal, sigmoidoscopy, and colonoscopy procedures
  • Prone: surgeries involving the posterior surface of the body, spine, neck, buttocks, and lower extremities

Perioperative Nursing

  • 3 phases: preoperative, intraoperative, and postoperative
  • Effects of surgery on a client: physical and psychological effects

Surgical Risk Patients

  • Extremes of age
  • Malnourished (emaciated/obese)
  • Dehydrated patients
  • Patients with severe trauma or injury, infection, or sepsis
  • Patients with cardiovascular disease
  • Endocrine dysfunction
  • Hepatic/renal disease

Medications Affecting Surgical Client

  • Antibiotics
  • Antidysrhythmics
  • Anticoagulants
  • Corticosteroids
  • Insulin
  • Diuretics
  • Antidepressants

Classifications of Surgery

  • According to urgency: emergent, urgent, required, elective, and optional
  • According to degree of risk: major and minor
  • According to purpose: diagnostic, exploratory, curative, ablative, and reconstructive

Surgical Skin Prep

  • Aseptic procedure to reduce resident and transient flora on the skin surface
  • Performed by the circulating nurse
  • Prior to draping
  • Antimicrobial solutions: povidone-iodine (Betadine) and chlorhexidine gluconate

Special Areas of Consideration

  • Eyes
  • Traumatic open wounds
  • Fractures
  • Tumors, aneurysm, and ovarian cyst
  • Dirty contaminated areas
  • Emergency preps

Sutures

  • Absorbable sutures: chromic, plain, polydiaxone (PDS), polyglactin 910 (Vicryl), polyglycolic acid (Biovek)
  • Non-absorbable sutures: silk, nylon, prolene (polypropylene)
  • Used either on skin wound closure or in stressful internal environments where absorbable sutures won't suffice

This quiz is about the signs and symptoms of malignant hyperthermia during general anesthesia induction and the patient's response to it. It covers the patient care considerations during this situation.
