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
