Study Notes

Dressing and Emotional Support

Change into a hospital gown and remove personal items to prevent loss during surgery.
Provide reassurance to the patient, highlight the supportive staff, and encourage any last-minute questions.

Intraoperative Types of Anesthesia

General Anesthesia: Induces unconsciousness using intravenous and inhalational agents.
- Stages:
  - Induction: Transition from awake to unconscious using IV drugs like propofol or inhalation agents.
  - Excitement: Involuntary movements and heightened reflexes; a brief phase.
  - Surgical Anesthesia: Safe for surgery; patient is fully unconscious.
  - Danger: Final stage; risk of respiratory and cardiovascular collapse if not monitored.
- Objectives:
  - Oxygenation, unconsciousness, analgesia, muscle relaxation, control of autonomic reflexes.
Regional Anesthesia: Blocks sensation in a specific body area.
- Common techniques include nerve blocks, spinal, and epidural anesthesia.
- Nerve Block: Anesthetic near a nerve for local sensation loss.
- Spinal Anesthesia: Injected into cerebrospinal fluid for lower abdominal and pelvic surgeries.

Surgical Incisions

Midline Incision: Vertical abdominal incision for wide access.
Pfannenstiel Incision: Transverse incision above the pubic symphysis, typically used in gynecological surgeries and cesarean sections.

Positioning the Client for Surgery

Supine Position:
- Patient lies flat on the back; common for various surgeries.
- Ensure padding to prevent pressure ulcers and monitor for complications.
Lithotomy Position:
- Patient lies on the back with legs elevated; commonly used for gynecological and urological surgeries.
- Careful leg handling is necessary to avoid strain.
Trendelenburg Position:
- Head lowered, legs elevated; used during shock or certain abdominal surgeries.
- Monitor for intracranial pressure and secure positioning.
Reverse Trendelenburg Position:
- Head elevated, feet lower; facilitates respiratory function.
- Monitor for hypotension and ensure securing.
Modified Fowler's/Sitting Position:
- Patient seated at a 45-60 degree angle; used for head, neck, and upper respiratory surgeries.
- Ensure back support and monitor respiratory function.

Postoperative Complications

Deep Vein Thrombosis (DVT): Caused by vein damage or immobility.
- Monitor for calf pain or tenderness; manage with hydration, ambulation, and anticoagulants.
Pulmonary Complications: Includes atelectasis and bronchitis.
- Management involves deep breathing exercises, incentive spirometry, and early ambulation.
Urinary Difficulties: Commonly retention and incontinence post-surgery.
- Caused by bladder spasms; induce voiding with environmental measures.
Intestinal Obstruction: Caused by adhesive loops of intestines.
- Symptoms include nausea and absence of bowel movements; management may include surgery.
Wound Complications:
- Infection: Monitor for fever, redness, or pus; maintain aseptic techniques and administer antibiotics.
- Hematoma: Monitor bleeding; prepare for clot evacuation if necessary.
- Wound Dehiscence: Disruption of the incision; Evisceration involves organ protrusion; inspect for bloody fluid.

Patient Inspection and Assessment

Normal Findings:
- Quiet respiration, pink nail beds, normal respiratory rate (12-20 breaths/min), symmetrical chest appearance.
Abnormal Findings:
- Barrel chest, funnel chest, pigeon chest, kyphoscoliosis indicate structural abnormalities.
- Crepitation indicates subcutaneous air leakage; asymmetry in expansion may indicate pleural effusion.
Palpation:
- Assess tenderness, temperature, and vibrations in the chest wall.
- Abnormal fremitus can indicate masses or pneumothorax.
Percussion:
- Normal resonance indicates healthy lung function; dull sounds may suggest fluid or solid masses.
Auscultation:
- Normal breath sounds include vesicular, bronchovesicular, and bronchial.
- Abnormal sounds include crackles, rhonchi, pleural friction rubs, and wheezes, indicating various pulmonary conditions.

Upper Airway Infections

Upper Airway Infections (URIs): Commonly caused by viruses, particularly rhinoviruses, leading to significant healthcare visits.
Rhinitis: Characterized by nasal inflammation; types include acute, chronic, allergic, and non-allergic.
- Symptoms include nasal congestion and sneezing; management focuses on symptomatic relief for viral causes.
