-
perioperative nursing
wide variety of nursing functions associated with the patient's surgical procedure
-
perianesthesia nursing
wise variety of nursing functions associated with the patient's care before and after anesthesia
-
preoperative phase
- begins when decision for surgical intervention is made
- ends with transfer of the patient to the operating room table
-
preoperative teaching
- assess level of understanding
- explain pre and post-operative procedures
- medications
- coughing and deep breathing exercises
- splinting of incision (putting a blanket/pillow over an abdominal incision when coughing)
- turning side-to-side
- leg exercises
-
preoperative medication restrictions
OTC drugs - stop taking two weeks prior to surgery
all other prescribed meds are usually taken up until the day of surgery, unless otherwise stated
-
with informed consent, the patient understands:
- nature and reason for surgery
- who will perform the surgery & others who will be present
- all available options and risks associated with each
- risks associated with surgical procedure and potential outcomes
- risks associated with anesthesia
-
preoperative medications: antianxiety
diazepam (valium)
-
preoperative medications: sedatives
midazolam
-
preoperative medications: analgesics
morphine sulfate
-
preoperative medications: anticholinergics (decrease oral secretions = decrease in chance of aspiration)
- atropine sulfate
- glycopyrrolate
-
preoperative medications: H-2 Receptor antagonist (for patients at risk for vomiting)
zantac, axid, tagamet
-
intraoperative phase
- begins when patient is admitted or transferred to the surery department
- ends when patient is admitted to the recovery area (post anesthesia/PACU)
-
universal protocol for preventing wrong site, wrong procedure, wrong person surgery
- preoperative verification process
- marking with operative site
- "time out" immediately before starting the procedure
-
anesthesia induction
the point at which anesthesia is inititated just prior to the first incision cut
-
general anesthesia
- controlled loss of consiousness
- protective reflexes lost
- sedation and analgesia
- muscle relaxation
- IV agents, inhalation agents, narcotics
-
general anesthesia complications
- CNS: emergence delerium; delayed emergence
- CV: hypotension, dysrhythmias, MI
- hypothermia (temp less than 95)
- repiratory: laryngospasm
- malignant hyperthermia
-
malignant hyperthermia (MH)
- chain reaction of abnormalities
- pharmacogenetic disease of skeletal muscle (muscle breakdown = heat production)
- inherited disorder (single defective gene)
- laboratory tests: caffiene, halothane contracture test
-
MH signs and symptoms
- early signs: muscle rigidity, tachycardia and dysrhythmias
- cutatneous changes
- tachypnea
- pyrexia (hallmark of disease but late sign)
-
management of MH crisis
- discontinue anesthesia/surgery
- administer 100% oxygen
- administer Dantrolene ASAP (reconstitte with 60 mL PF sterile water) - ONLY drug that can treat MH
- patient cooling
-
types of regional anesthesia
- spinal
- epidural
- caudal
- peripheral nerve block
- intravenous (bier block)
- infiltration block
- field block
- topical
- local
-
advantages of regional anesthesia
- fewer complications
- decreased pain
- faster recovery
-
dermatomes
- used to determine level of block
- access level using a sharp, dull, or cold test item
-
MAC
- monitored anesthesia care
- administered by anesthesia provider
- pt maintains own airway
- all IV
-
conscious/moderate sedation
- minimally depressed level of consciousness in which the patient retains the ability to maintain a patent airway independently and continuously and is able to respond appropriately to verbal commands
- administered by a non-anesthesia provider who has received speial training
-
postoperative phase
- begins with the admission of the patient to the recovery area
- ends with a follow-up evaluation in the clinical setting or at home
-
PACU care
monitoring patient for sings and symptoms of anesthesia and/or surgery/procedure complications
-
postoperative assessment
vital signs are the first item assessed -- RR is most important!
-
wound dehisscence
- seperation of the wond edges
- more likely wih vertical incisions
- may be caused by a bacterial infection or poor wont healing
-
evisceration
- protrusion of loops of bowel accompanied by escape of pink, serous drainage
- more likely in patients who are older, obese, diabetic, or malnourished
- emergency situation - patient must be readmitted to OR
- prevention: splint incision
-
common complications
- urinary retention
- pulmonary problems: atelectasis, pneumonia, embolus
- thrombophlebitis
- decreased GI peristalsis (prevented by BG tube, encourage early ambulation)
