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”

Page 5: Procedural sedation in emergency medicine

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).

Page 6: Procedural sedation in emergency medicine

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.

Canadian Consensus Guidelines

Page 26: Procedural sedation in emergency medicine

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.

Page 27: Procedural sedation in emergency medicine

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

Page 28: Procedural sedation in emergency medicine

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

Page 29: Procedural sedation in emergency medicine

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.

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.

Page 68: Procedural sedation in emergency medicine

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.

Page 69: Procedural sedation in emergency medicine

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)

Page 70: Procedural sedation in emergency medicine

Documentations

Don’t forget …..

Must ….

Page 71: Procedural sedation in emergency medicine

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

Page 72: Procedural sedation in emergency medicine

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.

Page 73: Procedural sedation in emergency medicine

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?

Page 74: Procedural sedation in emergency medicine

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

*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.

Capnography?

*Although not essential this indicates if

patient is ventilating

adequately.

*This will indicate hypoventilation

before pulse oximetry.

*Currently available to intubated

patients only

Page 78: Procedural sedation in emergency medicine

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.

Page 79: Procedural sedation in emergency medicine

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?

Page 80: Procedural sedation in emergency medicine

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).

(frequently the third) Aldrete can be the D/C score.

Page 83: Procedural sedation in emergency medicine

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

Page 84: Procedural sedation in emergency medicine

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.).

physician immediately after the change in the patient's condition,

increase oxygen delivery, call for assistance and consider reversal

agents.

B. Continue to monitor for further changes; reduce the next dose of

sedation medication by half.

C. Document the patient's status on the assessment form; notify the
