Perioperative Flashcards
Informed consent for a surgical procedure is necessary when a procedure meets the following four conditions:
- invasive procedures, such as surgical incision, a biopsy, a cystoscopy, or paracentesis
- procedures requiring sedation and/or anesthesia
- a nonsurgical procedure, such as an arteriography, that carries more than a slight risk to the patient
- procedure involving radiation
Emergent:
pt requires immediate attention; disorder may be life threatening, without delay; severe bleeding, bladder or intestinal obstruction, fractured skull, extensive burns, gun shot, GI obstruction, stabbing
Urgent:
pt requires prompt attention, within 24-30 hours, acute gall bladder infection, kidney or ureteral stones
Required:
pt needs to have surgery, plan within a few weeks or months, prostatice hyperplasia without bladder obstruction, thyroid disorders, cataracts
Elective:
pt should have surgery, failure to have surgery not castrophic, repair of scars, simple hernia, vaginal repair
Optional:
decision rests with pt, personal preference, cosmetic surgery
Vitamin K
essential for normal blood clotting
Vitamin C
allow for collagen formation to strengthen the wound
protein
enhances wound healing
Restriction of nutrition/fluids
prevent aspiration
Intestinal preparation
allow satisfactory visualization of the surgical site and to prevent trauma to the intestine or contamination of the peritoneum by fecal matter colonoscopy allows visualization of the colon
Urinary catheterization
performed in the OR as necessary, monitor intake and output, usually remove post opp day one to decrease risk of infection
Administration of preoperative medications
use is minimal with ambulatory or outpatient surgery. If prescribed, it is usually administered in the preoperative holding area
Anticoagulants –
can increase the risk of bleeding during the introperative and postoperative periods; should be discontinued in anticipation of elective surgery. The surgeon will determine how long before the elective surgery the pt should stop taking it, depending on the type of planned procedure and the medical condition of pt
Anti-seizure agents –
IV administration of med may be needed to keep the pt seizure-free in the intraoperative periods
Corticosteroids –
cardiovascular collapse can occur if discontinued suddenly. A bolus of corticosteroids may be administered IV immediately before and after surgery.
Diuretics –
during anesthesia, may cause excessive respiratory depression resulting from an associated electrolyte imbalance
Insulin –
IV insulin may need to be administered to keep the blood glucose within normal range
Aspirin is withheld ____ days before surgery, if possible, because it acts by
___________________
7-10 days; Inhibiting platelet aggregation
Diabetics undergoing surgery are at risk for four major complications:
Hyperglycemia, hypoglycemia, acidosis
List three significant nutritional concerns for the elderly surgical patient:
pre-op - dehydration, hypovolemia, and electrolyte imbalances
post-op – wound healing, return of normal bowel function, and fluid and electrolyte imbalance
Name three primary goals necessary to promote postoperative mobility:
Improve circulation, prevent venous stasis, promote optimal respiratory function (insentive spirometry increase lung expansion)
After administration of a preoperative medication, what patient safety measures must be maintained:
Keep pt up in bed with side rails raised cause medicine can cause lightheadedness or drowsiness. Observe the t for untoward reaction. The immediate surroundings are kept quiet to promote relaxation
Who is responsible for initiating and what does the phrase “time out” mean during the intraoperative period
Circulating nurse; second verification of the surgical procedure, every member of the team verifies the pt, procedure, and surgical site using objective documentation and data before beginning surgery
Stage I of General Anesthesia
beginning anesthesia – as the pt breathes in the anesthetic mixture, warmth, dizziness, and a feeling of detachment may be experienced
Stage II of General Anesthesia
excitement – characterized by struggling, shouting, talking, singing, laughing, or crying, often avoided if the anesthetic agent is administered smoothly and quickly
Stage III of General Anesthesia
surgical anesthesia – reached by continued administration of the anesthetic vapor or gas
Stage IV General Anesthesia
medullary depression – reached if too much anesthesia has been administered
What nursing assessment indicates that a patient has recovered from the effects of spinal anesthesia?
Return of sensation
