• Anesthesia provider (anesthesiologist or CRNA) • Circulating nurse gives the verbal “hand-off” report to PACU nurse. • Postoperative care is provided initially in the PACU by a ACLS certified RN. • Initial postoperative care: • assessments, administering medications, managing client’s pain, preventing complications, and determining when a client is ready to be discharged from the PACU. • PRIORITIES During the immediate postoperative stage: • airway patency • ventilation • circulatory status Common Post-OP Complications: Immediate to 48 hr: • Respiratory depression • Hypoxia • Wound Hemorrhage • Nausea • Shock • Urinary retention (up to 3days) First 48hr: • Atelectasis After 48 hr: • Hypostatic pneumonia 2-4 days: • Paralytic ileus (decreased peristalsis) 3-5 days: • Wound infection • > 4 days: • UTIs • Thrombophlebitis • Wound dehiscence/evisceration Risk FactorsUrinary retention (up to 3days) First 48hr: • Atelectasis After 48 hr: • Hypostatic pneumonia 2-4 days: • Paralytic ileus (decreased peristalsis) 3-5 days: • Wound infection • > 4 days: • UTIs • Thrombophlebitis • Wound dehiscence/evisceration Risk Factors for Postoperative complications • Immobility (respiratory compromise, thrombophlebitis, pressure ulcer) • Anemia (blood loss, inadequate/decreased oxygenation, and healing factors). • Hypovolemia (tissue perfusion). • Hypothermia (surgical wound infection, altered absorption of medication, coagulopathy, and cardiac dysrhythmia). • Cardiovascular diseases (fluid overload, deep-vein thrombosis, arrhythmia) • Respiratory disease (respiratory compromise) • Comorbidities affecting Post-Operative period: • Immune disorder (risk for infection, delayed healing) • Diabetes mellitus (gastroparesis, delayed wound healing) • Coagulation defect (increased risk of bleeding) • Malnutrition (delayed healing) • Obesity (wound healing, dehiscence, evisceration) • Older adults ( more susceptible) PACU Assessments and Nursing interventions: • Full Head to Toe assessment with priority given to airway, breathing, and circulation (ABCs) • Nursing monitoring and management: • Airway and Breathing: • ( artificial airway, O2 Sat (>92% or at preop. levels) • Respiratory pattern ,breath sounds, chest wall movement, and Auscultate lung sounds • Administer humidified oxygen. • If unable to cough: • Suctioning with Yankauer suction ( thick oral secretions), or • Large French suction catheter (nasopharyngeal or nasotracheal secretions) • Circulation: Monitor • S & S of internal bleeding (abdominal distention, visible hematoma under/near the surgical site, tachycardia, hypotension, increased pain). • External Bleeding. • Assess for hypervolemia and hypovolemia. • Assess skin color, temperature, sensation, and capillary refill. • Check mucous membranes, lips, and nail beds for cyanosis. • Assess and compare peripheral pulses for impaired circulation, deep-vein thrombosis (continue DVT prevention measures) • ECG readings and apical pulse Fluid and electrolyte balance. • Vital Signs: • Until stable (every 15 min) and assess for trends. • Prevent hypothermia • Positioning: • If responding to verbal stimuli: Semi Fowler’s if not contraindicated (facilitate chest expansion) • If unresponsive or unconscious: Right or Left Lateral position (to prevent aspiration) • If hypotension or shock develop: Elevate legs and lower the head of the bed. • If recovering from spinal anesthesia: Do not elevate legs higher than placement on a pillow • Avoid placing a pillow under the knees or engaging the knee gatch of the bed ( decrease venous return). • Response to anesthesia (sedation, nausea and/or vomiting), Monitor • LOC • Movement, sensation • Antiemetics • I & O: Monitor • Fluid and electrolyte balance • Skin turgor, diaphoresis • Emesis, drains, NG tubes, IV fluids, urine, Blood products. • Isotonic IV fluids (0.9% sodium chloride, lactated Ringer’s, dextrose 5% in lactated Ringer’s) • Palpate bladder for distention. • Urinary catheters patency: Urine output less than 30 mL/hr may indicate hypovolemia. • Surgical wound, incision site, and/or dressing • Pain • Monitor recovery from anesthesia by using the Aldrete scoring system. • Criteria indicating readiness for discharge from the PACU • Aldrete Score of 8 to 10 • Stable vital signs • No evidence of bleeding • Return of reflexes (gag, cough, swallow) • Minimal to absent nausea and vomiting • Wound drainage that is minimal to moderate • Urine output of at least 30 mL/hr • The anesthesiologist must sign out the client before transfer to another unit or discharged to home. DIABETES • Type 2 – Impaired insulin production/Impaired insulin use Etiology and Risk Factors • Type 2 – • Insulin production is less or use is impaired or reduces insulin sensitivity o Hereditary – major role o Obesity o Eating habits o Sedentary life style Pathophysiology • Type 2 – • Causes – leading to high glucose • Stages – Desensitization – Failure of beta cells to respond to high glucose levels • Insulin Resistance – Production of glucose by liver despite of high glucose levels • Inability of fat and muscle tissue to take up glucose – peripheral insulin resistance Clinical Manifestations • 3 p’s – Polydipsia, Polyuria and Polyphagia • ^ Hyperglycemia S/S: Fatigue, Blurred vision, Slow wound healing, Itchy skin-“Hot and dry, blood sugar high” • v Hypoglycemia S/S: Sweating, Hunger, Trembling, Anxiety, Confusion, Blurred vision-“Cool and clammy, need some candy” • Weight loss • Ketone bodies- Diabetic Keto Acidosis • Fruit breath odor, headache, N,V, Abd.
