What is
Procedural
Sedation?To reduce patient anxiety
and awareness
To facilitate a painful medical procedure
Patient maintains their airway & breathing
“Conscious sedation”“Deep sedation”
What is Procedural Sedation?
• Procedure (n) A series of steps taken to accomplish an end. Examples: EGD, bronchoscopy, fracture/dislocation reduction, cardiac catheterization
• Sedation (n)
Reduction of anxiety,
stress, irritability, or
excitement by
administration of a
sedative agent or
drug. Procedural Sedation (n) Reducing anxiety or stress with medications in order to perform a procedure. These medications may include, but are not limited to Opiates (e.g., morphine, fentanyl) and Benzodiazepines (e.g., midazolam, lorazepam).
The goals of PSPatient safety & welfare the first priority.
Adequate analgesia, anxiolysis, sedation and amnesia during the performance of painful diagnostic or therapeutic procedures in the ED.
Minimize the adverse psychological responses
Control motor behaviour that inhibits the provision of necessary medical care.
Return the patient to a state in which safe discharge is possible.
Procedural
Sedation PositivesAvoids the discomfort associated with local or regional anaesthetictechniques.Doesn’t affect anatomyRelatively simple technique

Definition Details Examples
ASA
PS 1 A
normal
healthy
patient
Healthy individual with no
systemic disease, undergoing
elective surgery. Patient not at
extremes of age. (Note: Age
is often ignored as affecting
operative risk; however, in
practice, patients at either
extreme of age are thought to
represent increased risk.)

hernia.
Fibroid uterus in an
otherwise healthy woman
ASA
PS 2 A
patient
with
mild
systemic

Individual with one system,
well-controlled disease.
Disease does not affect daily
activities. Other anesthetic
risk factors, including mild
obesity, alcoholism, and
smoking can be incorporated
at this level.
Non-limiting or only
slightly limiting organic

However, there is no
immediate danger of
death from any
individual disease.
Severely limiting organic heart
disease. Severe diabetes with

Patient who is in
imminent danger of death.
Operation deemed to be a
last resort attempt at
preserving life. Patient not
expected to live through

ASA Scores & PSA• The ASA classification is not validated
outside of the OR.
• Malviya et al showed an increased risk
of adverse sedation-related events in
paediatric patients with an ASA > 2.
“The patient’s ASA status should be
determined. For non-emergent
procedures, ED sedation and
analgesia should be limited to ASA
class 1 or 2 patients.”Class B, Level III
Procedural sedation and analgesia in the emergency department
Canadian Consensus Guidelines
The Last Supper
Fasting & PSA
ANZCA recommendations for healthy elective GA patients:
2 h NPO for liquids
6 h NPO for solids
The risk of aspiration during PSA is extremely low.
There is no evidence that fasting improves outcome during procedural sedation and analgesia.
One large paediatric study of ED procedural sedation showed no increase in the number of adverse events in patients that were not fasting.
Starved for how long…?
Controversial.
Probably not as rigid as anaesthetic guidelines for GA...
Depends on degree and duration of sedation
Starship CED paediatric guideline:
Clear fluids: at least 2 hours
Non-clear fluids and solids: at least 4 hours
Oral Intake
GuidelinesAge does not matter – what they took orally is the issue.
Ingested Material Minimum Fasting Period
Clear Liquids 2 hours
Breast Milk 4 hours
Infant Formula 6hours
Non-clear Liquids 6 hours
Light Meal 6 hours
Options for the patient not within these guidelines:
Cancel the Procedure
Postpone the Procedure
Emergent
Procedures
Emergent Procedures : life- or organ (i.e., CNS) saving procedures (consult anesthesiology)
Urgent procedure are those which need to be done in 2-4 hrs
•Document why it is urgent; •Assess the need for sedation and preferably administer none•Consider postponing or consult anesthesiology•Monitor the patient's airway closely •Look for active or silent regurgitation and aspiration.
PATIENT SELECTION
Can you hold the fort if something goes wrong?
BREATHING & CIRCULATION:
Lung disease?
Stable cardiac status?
BP stable?
Medications
Allergies (e.g. watch out for soy, eggs: Propofol)

Considerations
When selecting a sedative, the following pharmacokinetic parameters should be considered to optimize response in a given situation.* Onset and Duration * Elimination Route * Accumulation * Drug interactions / potentiations* Cross-Tolerance
e.g. patients with prior opiate use may require higher doses of opiates; those with prior ethanol exposure may require larger doses or benzodiazepines, etc.

PATIENT PREPARATION
Explanation
Consent
Secure IV access
is mandatory.
Informed Consent
* The person performing the procedure (clinician) is to review objectives,
risks, benefits and alternatives of Procedural Sedation (informed consent)
* This can be done at the same time as the procedure is explained
* Informed consent for the sedation does not require a patient signature.
Rather there is a check box on the Pre-Procedure/Pre-Sedation Assessment
form. If paper forms are not available, it is the responsibility of the clinician
to document this in the pre- procedure note.
* If the person who will monitor the patient (assistant) finds that the patient has
additional questions, the person performing the procedure (clinician) will be
contacted to answer these questions before sedation is given.
Assistant Responsibilities
– Patient assessment and
appropriate documentation
throughout the procedure
– Reassure patient and monitor
patient awareness.
– Provide comfort measures as
needed
– Notify clinician of changes /
concerns.
– Documentation of required
parameters.The Assistant is not to leave patient bedside for any
reason during the procedure (although may assist
the clinician with short, interruptible tasks) The
assistant must be able to drop those tasks if the
patient needs attention)
Documentations
Don’t forget …..
Must ….
Pre-Procedure/Pre-Sedation Assessment form (required
for all procedural sedation) includes documentation of the
following:
Review of Systems:
*Can be completed by nursing or medical staff. If completed by nursing,
must
be reviewed by the clinician completing the pre-procedure
assessment.
Focused Assessment:
Must be completed by a licensed independent practitioner according
to
Medical Staff Bylaws. It includes procedure-specific parameters, and
addresses any new or pertinent data seen on the Review of Systems.
Airway Assessment:
* Aim is to plan for airway management if that would be necessary.
* Assessment parameters may include
* Assessing dentures, loose teeth, partials, etc.
* When the patient opens his/her mouth, how easily can the cords
and
pharynx be visualized should intubation be necessary.
* Are there physical limitations, which would impede proper
positioning
Pre-Procedure/Pre-Sedation Assessment form
(required for all procedural sedation) includes
documentation of the following:
Risk Assessment (ASA PS Score)
*To be completed by clinician, even if you’re not Anesthesia
personnel
Risks/Benefits/Alternatives for Sedation
*Required discussion with patient should be documented
either on outpatientforms, or in procedure note
Risks/Benefits/Alternatives for Procedure
*As above, with the addition of signature on procedural
consent
Sedation Plan:
*The level of sedation that was presented to, and accepted by
the patient. This must be documented before initiation of the
procedure.
Prevent wrong site / wrong patient / wrong
limb / wrong equipment• Site Verification / Marking “YES” on the procedure site
– Must be completed before the procedure starts
– Is the responsibility of the person performing the procedure (clinician)
– Should be a process which includes patient input / verification / understanding
• TIME OUT!
– To be completed immediately before the first dose of sedation / start of the procedure.
– Is the responsibility of the clinician, although may be documented by the assistant
– Should be a group interaction (clinician, assistant, others present in the room)
– Includes four questions:1. Is this the Correct Patient?2. Is this the Correct Procedure?3. Is this the Correct Site?
4. Is this the Correct Equipment?
Intra-procedure Monitoring requirements
*BP, Pulse, Respiratory Rate, SpO2
Immediately before the procedure / first dose of sedation, monitored
frequently and documented every 10 minutes throughout the
procedure and recovery period.
*Mechanical noninvasive blood pressure is preferred, however may
use manual (cuff) method.
*Continuous Pulse Oximetry
*Sedation
*Assessed and documented with vital signs
*RASS Sedation Scale
Richmond Agitation Sedation Scale (RASS)

-4 Deep sedation No response to voice, but movement or eye opening to
physical stimulation
-5 Unarousable No response to voice or physical stimulation
Intra-procedure Monitoring requirements
EKG monitor
*Assistants may not be able to perform rhythm
interpretation
*Identify when more in depth patient assessment
is required
1). For example: heart rate drops, assistant
may stimulate
patient, check BP, or other
2). Another example: heart rate accelerates,
assistant may ask patient about comfort level.
*Assistants should notify the clinician for any
noticeable changes in rhythm, rate, or other
concerns noted on monitor for further medical
direction.
Intra-procedure Monitoring
requirements
Capnography?
*Although not essential this indicates if
patient is ventilating
adequately.
*This will indicate hypoventilation
before pulse oximetry.
*Currently available to intubated
patients only
Responsible Individual
for discharge planning
• The person who will provide the patient’s ride home and be
available to the patient after the procedure will be identified
before the procedure begins.
• This person may be an adult, or someone in their late teens that
the patient feels comfortable with.
• If the patient is an outpatient, this person frequently
accompanies the patient to the hospital
• If the responsible individual is not present, hospital staff need to
verify the individual by telephone.
• If the patient is an inpatient, it may not be necessary to identify
this individual pre-procedure.
• If the inpatient is discharged within 24 hours of the
procedure, the patient must be discharged to a responsible
individual.
Responsible individual?
• For outpatients: If either the clinician (person performing
the procedure) or the assistant (person monitoring the
patient) feels the individual present would not be
appropriate in this role, or the patient has no one
identified, the clinician needs to determine:
– Can the procedure be cancelled (or postponed) until a
responsible individual is available?
– Should the procedure be completed and the patient
kept an additional 4 hours after discharge criteria are
reached, then released with appropriate
transportation?
Discharge to Responsible Person
Guidelines:
Best Practice: Patient accompanied by Responsible
Adult
If no responsible adult present at patient admission,
staff should
-Verify via phone the responsible adult who will be
present at discharge
-Or
-Identify a responsible individual to whom the patient
can be reasonably transported after the procedure
-Or
-Cancel the Procedure!
How do I know the
person is
responsible?
Use your
professional
judgment.
If no responsible adult present after the procedure is completed,
observe the patient for 4 hours after completion of the recovery
period, then discharge (patient must not drive for 24 hours after
sedation).

Discharge score must be a minimum of pre-procedure score minus
one, with stable vital signs to meet discharge criteria.
TOTAL:
Baseline must be done before sedation initiated. This
is what post-procedure Aldretes are compared to.
Post Procedure is done at the end of the procedure, then every 10 minutes until patient
meets recovery criteria. A minimum of 3 aldrete scores must be completed before the
patient can be identified as “recovered” When recovery criteria are met, the last
(frequently the third) Aldrete can be the D/C score.
Recovery criteria
*A minimum of two consecutive Aldrete scores are baseline minus one
with stable vital signs
*The patient’s room air oxygen saturation must be back to baseline
*Sufficient time (i.e., a minimum of 1 hour) should have elapsed after the
last administration of reversal agents (naloxone, flumazenil) to ensure
that
the patient does not become resedated after reversal effects have
abated.
* Patients who will be discharged to home and receive IV
medications for relief of pain, nausea, vomiting etc. must be
observed no less than two consecutive Aldrete / vital sign
assessments following administration of such medication
Discharge criteriaVital signs stable (Vital signs include BP, HR, R,& O2 Sat. The VS are
determined to be stable if they are consistent with the patient’s age and with the
patient’s pre-operative VS)
Swallow, cough present (patient demonstrates ability to swallow fluids and
is able to cough
Able to ambulate (patient demonstrates ability to ambulate at pre-procedure
level)
Nausea, vomiting, dizziness is minimal
Absence of respiratory distress (patient’s respiratory effort consistent
with pre-procedure status)
State of consciousness (patient is alert, oriented to time, place and person
consistent with pre-procedure level of consciousness).
Level of comfort (Pain controlled as per BJH pain policy)
Post-procedure (oral and written) discharge instructions are
given to the patient and/or significant other regarding the following: purpose and
expected effects of sedation, patient’s care, emergency phone number,
medications, dietary or activity restrictions, and necessary precautions (e.g., no
driving for 24 hours, avoid alcohol and use of power tools, etc.).
