Q

dizziness and fainting
- increased risk when
- highest risk with

A
  • in first 24-48 hours
  • spinal/ epidural as it freezes motor (movement), sensory (feeling) and autonomic (muscle tone) nerves. When the patient stands the vessels do not contract (as they should to prevent blood flow from moving to the feet) so blood flows to feet, blood pressure drops and patient faints

29
_______accounts for the majority of cases and has usually arisen from a distant vein and travelled to the lungs via the venous system
thrombosis
30
DVT- can lead to especially with ____ surgery
PE, assess for calf pain and redness, especially with orthopedic surgery
31
hemorrhage/bleeding Risk factors: Assessment: Intervention:
Risk factors: Trauma, long surgical time, blood thinners Assessment: Assess patient’s dressing, vital signs and lab values; Assess for increase pulse and symptoms of shock for internal bleeding Intervention: Change dressings prn after 24-48 hours postop unless directed otherwise Hold pressure on wound and call for help if needed and notify doctor Empty and measure drains to assess amounts
32
Hematoma what assessment intervention
Area immediate to surgical site that continues to swell, filling with blood Assessment: Watch for firmness, swelling, discolouration (bruising), mark it with a pen Intervention: Apply pressure dressing, call surgeon if continues, occasionally needs to be drained
33
Hypotension RF Assessment interventions
Risk factors: fluid/blood loss, fluid deficit, peripheral pooling of blood, vasodilation from anaesthetic (also decreases BP), medications Assessment: Decreased LOC and BP, dizzy, nausea, pale * Hypovolemic Shock decrease BP, increase pulse, cold, clammy, pale * Patient can develop orthostatic hypotension when changing from lying to standing too quickly. Interventions: replace lost fluids (insure strict I&O measuring)
34
HTN causes assessment
Causes: pain, delirium, hypoxia, gastric or bladder distention, fluid overload Assessment: regularly according to policy and PRN- BP, pulse, cap. refill, absence of chest pain, RR, extremities, crackles, edema
35
normal prehigh high BP
120/80 or less 121-139/81-89 140/90 or higher
36
cardiac dysfunction
- Myocardial infarctions/ischemia - CVA/TIA - Dysrhythmias - Hypo/hypertension - Pulmonary embolism
37
cardiac dysfunction causes assessment interventions
Causes: effects of drugs (pre, intra, & post op), prolonged surgical time, trauma, co-morbidities, acid/base - fluid/electrolyte imblaances Assessment: Monitor VS as per protocol, telemetry/ECG monitor (depending on acuity/surgery), CWMS, I&O balance, Interventions: ?cardiac/DVT heparin protocol, replace/excrete fluids & electrolytes,
38
Fluid and Electrolyte Imbalances: | 4 examples
Hypo/hypervolemia (fluid) Hypo/hypercalcemia (Ca) Hypo/hyperkalemia (K+) Hypo/hypernatremia (Na+)
39
Fluid and electrolyte imbalances Causes: Assessment: Intervention:
Causes: trauma, blood loss, too much fluid replacement in OR, prolong surgical time, drugs, gastric losses Assessment: Monitor for signs and symptoms, full CVA assessment, lab values, telemetry/ECG monitoring, monitor I&O Intervention: Treatment based on levels – fluid replacement/diuretics, electrolyte replacement/excretion
40
N/V Causes: assessment: Intervention:
Causes: Anesthetic, drugs, pain, NPO status Assessment: monitor – like pain, it is what they say it is; monitor I&O Intervention: administer anti-emetics, HOB elevated to prevent aspiration of emesis, slow progression of diet (CF, FF, regular)
41
paralytic ileus causes assessment interventions
Causes: delayed return of GI peristalsis Assessment: assess for presence of bowel sounds, abd. distention, abd. pain, N/V, diminished peristalsis Interventions: Encourage early ambulation of patients to prevent ileus – bowel motility and patient mobility Use splinting of abdomen for any abdominal surgeries to protect incision Starting bowel protocol with patients early on esp. with narcotic use Keep patient on fluids until active BS
42
urinary retention = causes assessment intervention
- Inability to void 6-8 hours post-op - This is a common immediate postoperative complication that can often be dealt with conservatively with adequate analgesia. If this fails, catheterization may be needed. - Causes: Anaesthetic, trauma to bladder, spasm of sphincters from pain or anxiety, spinal and epidural anaesthesia delays the recovery of autonomic bladder reflexes - Assessment – inability to void, distended bladder, discomfort. patients post-op for void ie. Bladder scan - Intervention: regular toileting, fluids, decrease use of narcotics, catheter if needed
43
UTI causes assessment intervention
Causes: very common, more in women, and elderly may not present with typical symptoms Assessment: I&O, monitor urine (frequency, cloudy urine, burning), fever, delirium (can cause disorientation and mental changes in the elderly) Intervention: Treat with antibiotics if needed and encourage adequate fluid
44
infection of wound causes assessment intervention
Causes: poor aseptic technique, poor post-op cleansing, poor patient hygiene, on rare occasions contamination in OR Assessment: redness around wound site of >2cm, purulent drainage, fever, warmth at site, growth from C&S swab of clean wound base Intervention: Treat with antibiotics, also silver antimicrobial dressings can be used
45
Dehiscence | - what - causes - usually occurs between day
- Inadequate wound closure, stress on incision from coughing or vomiting, distention, decreased circulation - affects about 2% of midline laparotomy wounds - is a serious complication with a mortality of up to 30% - usually occurs between 7 and 10 days postoperatively
46
dehiscence causes assessment intervention
Causes: Malnutrition, obesity, older age Assessment: monitor site Intervention: Initial management includes sterile dressing to the wound, opiate analgesia, fluid resuscitation and early return to OR for re-suture; Removing alternate sutures/staples during removal decreases likelihood of occurrence
47
evisceration intervention
- Cover entire area with sterile NS soaked dressing and cover dressing. - Monitor for signs of shock, place pt. in bed with knees to chest and call surgeon immediately - Cover entire area with moist sterile dressing and monitor for signs of shock, call surgeon
48
potential breathing complications immediately post op | A P P P R
Aspiration: unable to maintain airway, vomiting medications, anesthesia Respiratory depression: opioids, medications, sedatives Pneumonia >2days: retained secretions, aspiration PE: DVT(immobility Pulmonary edema: fluid overload
49
why a post op patient might be hypervolemic (2)
- stress response causing activation of RAAS, ADH an aldosterone which retain water and Na - too much IV fluids
50
What patients would be at increased risk for fluid overload? | 3
renal (cant remove excess fluid) HF ( elderly (comorbs)
51
Dec BP, with N pulse and warm dry pink skin usually represents
- residual vasodilating effects of anesthesia - continue to monitor
52
Dec BP with inc HR, cold clammy and pale skin may be caused by
- impending hypovolemic shock - requires immediate attention
53
signs of hypovolemia (5)
- cool, clammy skin - decrease LOC - increase RR - Increase HR - decreased BP
54
