3-if morbidily obese
5-will die if not going to surgery
Anesthesia Management Options
Communicate available choices

Identify Plan A and Plan B

Nice to know if they absolutely refuse /object an option (you may not be the one conducting the informed consent)
What is the purpose of Informed Consent?
Educates the patient about the events surrounding the procedure to be performed
Based on patient’s right to self-determination

Protects the caregiver from libelous acts.
What is the definition of Informed Consent?
The patient has agreed to undergo
a procedure after receiving a clear
description of the nature of the
procedure, anesthetic options
available, and any potential side-
Informed Consent
Choice of Technique
Site of surgery
Coexisting disease
Position of operation
Elective or emergency
Patient preference
What anesthetic risks should be disclosed?
Lundquist v Ayerst Laboratories, Inc the court said “the anesthesia provider is not required to inform the patient of every conceivable risk, but only significant risks”
Markarian(1991) you don’t have to site every risk, so as not to unduly alarm the patient.
Airway trauma
Sore throat
Dental Injury
Peripheral Neuropathy
Allergic drug reaction
What anesthetic risks should be disclosed?
What are substantial risks? (those inherent in the instrumentation of the mouth, invasive line placement or regional anesthesia)

Accompany risks with measures to minimize harm (use of monitors, drugs…..)

Include rarity of the risk (e.g.. chance of postdural puncture headache < 2%)
What are the elements of Informed Consent? [4]
Disclosure of information – need to make an informed judgment
Comprehension of information – must be understandable, minimize medical jargon
Voluntary – free of coercion or controlling influences. (There are always pressures)
Capacity to Consent – requires a capable decision maker
Who can render Informed Consent?
Persons of legal age
Legal guardians (step-mom/dad)
Emancipated minors (Those under the legal age who are considered legally adult for consent purposes)
Married, widowed or divorced
Patient is a parent
Patient is a member of the armed forces.
Patient is pregnant
Living separate and apart from his or her parent(s) or guardian & managing own finances.
What are special charting concerns with OB anesthesia? [4]
For c-sections note
the following:
Time of Intrauterine incision
Time of birth
Sex of baby
APGAR readings
What is special about DNR in the OR?
AANA ethical guidelines state these orders acknowledge a patient’s right to die with dignity.
Automatic suspension fails to comply with this right.
Raises issue of potential battery.
Clarify all possible scenarios in the perioperative phase and exactly what DNR means. Document discussion and have patient initial/sign.
What is special about the Jehovah Witness patient in the OR?
Clear documentation of the extent to which the patient wishes transfusion of blood or blood products under life threatening situations.
Child – parents need to know transfusion therapy could occur in event of life threatening hemorrhage (via a court order)
Standardized consent

What should I be concerned about in reference to the law and charting?
It is a legal document and is admissible in court as evidence demonstrating the kind, standard, or quality of care delivered.
Although accurate and complete charting doesn’t prevent complications or potential legal concern, it can minimize discussion concerning the appropriateness of anesthesia management or compliance with standards.
Charting and the Law
Be clear, concise, factual, and objective
Mod amount of emesis vs 200cc
Patient appears upset vs patient crying enroute to OR
Meds given without a clear rationale must be explained (give a response too )
