Patient Advocate!
- Assess,
- confirm, monitor, prepare, direct, anticipate, provide, coordinate, count,
- transport, collaborate, teach, position, skin prep, document, protect, specimen
- handling, secretarial duties, other
-
Principles of aseptic technique
- Only sterile
- items may enter a sterile field
- If sterile
- comes in contact with unsterile, it
is contaminated
- Gown is
- sterile only on the front from chest
- to table level;
- sleeves to 2” above elbow
- Maintain wide
- margin between sterile and
unsterile
- Contaminated
- items must be removed
immediately
-
Principles of aseptic technique (cont.)
- Table is
- sterile only at tabletop level
- Edges of a
- sterile package are considered
- contaminated
- Bacteria
- travel on wind currents
- Bacteria
- travel through moist fabrics
- Bacteria live
- on hair, skin and respiratory
- tracts and must be confined by
- appropriate
attire
And finally……….
THE FIVE-SECOND RULE DOES NOT APPLY!
-
The patient in the OR
- Brought in by
- anesthesia provider and circulator - watch noise levels
- Moved over to
- OR table - safety
- Safety straps
- and monitors applied
- Pre-oxygenation
- – guided imagery
- Insertion of
- lines, foley
Positioning
Skin prep
Draping
“Time Out”
-
anesthesia
General Anesthesia – “Balanced Anesthesia”
Loss of sensation & consciousness
Muscle relaxation
Analgesia
Elimination of somatic, autonomic
and endocrine response (coughing,
gagging, vomiting)
Phases of General Anesthesia -
Induction-most dangerous time
Maintenance
Emergence-most dangerous time
-
Intraoperative anesthesia drugs
IV AGENTS (Induction)
Barbiturates – Pentothal, Brevital
Rapid induction, short duration
Cardiac Side effects
- Nonbarbiturate hypnotics – Amidate,
- Propofol
Rapid onset and elimination
Cardiac Side effects
Propofol may also be used for anesthesia maintenance
-
Intraoperative anesthesia drugs (cont.)
INHALATION AGENTS (maintenance)
Volatile liquids – halothane, enflurane,
isoflurane, desflurane, sevoflurane
(muscle relaxation, bronchodilation,
rapid excretion)
Gaseous agents – nitrous oxide (weaker than volatile liquids, may be used in conjunction with volatile liquids)
Ketamine – Dissociative anesthetic (rarely
used due to hallucinations, nightmares,
increased heart rate, B/P, intraocular
and intracranial pressure)
-
Adjuncts to general anesthesia
- Opoids – Sublimaze, Sufenta, Morphine, Demerol, Alfenta, Altiva, Methadone (used
- in all three phases, causes
- respiratory depression)
Benzodiazepines – Valium, Versed, Ativan
(Induction and maintenance, conscious
- sedation, sedation during regional or
- local)
- Neuromuscular Blockers – Anectine,
- Norcuron,
Tracrium, Pavulon, Zemuron (paralysis)
- Antiemetics – Inapsine, Zofran, Reglan,
- Compazine,
Phenergan
-
Local anesthesia
- Beer
- Block for arm to restrict blood.. 2 hour sx. Only with tourniquet
- Operative
- procedure is performed without loss of consciousness
Topical application – gels, creams
Local infiltration – lidocaine, marcaine
into tissues
Peripheral nerve block – into or around nerve or group of nerves
Bier block – exsanguination then IV
injection provides anesthesia and bloodless field
Spinal block – into CSF
Epidural block – outside the dura
-
Catastrophic events during surgery
- Anaphylactic reaction – hypotension,
- tachycardia, bronchospasm, pulmonary
- edema (antibiotics and latex most common
- causes)
Latex Allergy –
Type IV – contact dermatitis
Type I – anaphylaxis- (Most serious)
Risk Factors – repeated exposure, hx of
asthma & hay fever, food allergies
- Malignant hyperthermia – rare but
- deadly
Reaction to Anectine, autosomal dominant
- Muscle rigidity, hyperthermia (late
- sign), hypoxemia, lactic acidosis, cardiac alterations,
- cardiac arrest
Treatment: Dantrolene
-
emergence
Airway
Paralysis
Safety
-
The Postoperative patient
PACU – Postanesthesia care unit
Critical care area
Transitional
Will be discharged to home or
clinical care area
Phase I – general anesthesia
- Phase II – ambulatory
- surgery
-
Pacu initial assessment
- Anesthesia
- & Circulator report to PACU nurse
Priority:
¡Respiratory – ABC’s
- ¡Circulatory – ECG monitoring, B/P,
- temp, skin color and condition
- ¡Neurological – LOC, orientation,
- sensory & motor
- status,
- pupil size & reaction
- ¡Fluid balance – I&O, IV’s,
- irrigation, drains
- ¡Wound assessment – pain, drainage,
- bleeding
¡Emotional support, reassurance
¡Ongoing assessment
-
Respiratory complications
- Obstruction –
- Tongue, laryngospasm, secretions,
- laryngeal edema
- Hypoxemia –
- Atelectasis, secretions, decreased respiratory excursion, hypotension, low cardiac output, fluid
- overload, sepsis,
- aspiration, bronchospasm,
- hypoventilation
TREAT THE CAUSE
-
Cardiovascular complications
- Hypotension –
- decreased fluid volume
- Hypertension –
- pain, anxiety, full bladder,
respiratory compromise, hypothermia,
preexisting hypertension
- Cardiac
- dysfunction – MI, tamponade, PE,
arrythmias, preexisting heart disease
TREAT THE CAUSE
-
Other COMPLICATIONS
- Emergence
- delirium – hypoxemia, anxiety,
full bladder, pain, preop anxiety
- Delayed
- awakening – prolonged drug action
- Pain – may
- prolong PACU stay
- Hypothermia –
- Age extremes at risk, increases recovery time
- Nausea &
- Vomiting – lengthens PACU time
TREAT THE CAUSE
-
