PSA
   Procedural sedation and analgesia (PSA) refers to the
    pharmacologic techniques of minimizing or eliminating a
    child‘s pain and anxiety related to invasive or potentially
    frightening treatments & procedures.
Historical Perspective
   AAP (American Academy of Pediatrics) seminal article
    1992 referred to as ―conscious sedation‖, & established
    guidelines for monitoring these patients.
   Defined as ―a depressed state of consciousness where the
    patient retains protective reflexes and responds
    appropriately to stimuli‖.
   AHCPR (Agency for Health Care Policy & Research)
    published federal guidelines for management of acute pain
    in adults & children.
Procedural Sedation Re-defined
 American College of Emergency Physicians re-named
  ―conscious sedation‖ as ―moderate sedation‖
                        because
Procedural sedation‘s goal was to medicate patients safely
  until they can tolerate unpleasant procedures; i.e, they
  aren‘t really ―conscious‖.
AHCPR Guidelines
1.   Provide adequate           3.Combine
     preparation of children     pharmacological & non-
     & families for procedure    pharmacological options
2.   Be attentive to             when possible (relaxation
     environmental comfort       & imagery/VR)
     (allow parents to stay,    4. If procedures will be
     quiet room, sign on         repeated, provide max
     door)                       S&A for 1st procedure
Four Levels of Sedation
The Joint commission and the American Society of
 Anesthesiologists (ASA) described the 4 levels of
 sedation.
     Anxiolysis
     Moderate Sedation
     Deep Sedation
     General Anesthesia
Minimal Sedation
   Anxiolysis or minimal sedation refers to a drug-induced
    state in which cognitive and motor function may be
    impaired. This state does not fall under the sedation
    monitoring strict guidelines.
Moderate Sedation
   Moderate sedation is a state of sedation in which a child
    responds purposefully to verbal commands with or
    without light tactile stimulation, and maintains protective
    reflexes.
Deep Sedation
   Deep sedation and analgesia is a drug induced depressed
    level of consciousness in which patients respond
    purposefully only to repeated or painful stimulation, and
    may be accompanied by the loss of protective reflexes.
General Anesthesia
   General anesthesia refers to the drug induced loss of
    consciousness in which there is no response to painful
    stimulus, and loss of protective reflexes.
requires the patient to be very still for the
duration of the procedure, which may be
frightening for the child)

Sedation for Emergency Procedures
   Incision and drainage
   Fracture reduction / splinting
   Repair of lacerations
Goals of Sedation
   Mood alteration in order to allay the patient‘s fear
    and anxiety
   Maintenance of consciousness and cooperation for
    those patients who must be awake enough to
    cooperate throughout the procedure
   Elevate the pain threshold with minimal changes in
    vital signs, protective reflexes and physiologic
    response
   Complete the procedure safely in minimum time
Sedation and Analgesia Goals


    Achieve adequate sedation with minimal risk, minimal
     time
    Minimize discomfort and pain
    Minimize negative psychological response by providing
     anxiolysis, analgesia, and amnesia
       Monitoring and Assessment
       Key Elements

   • III: A child with severe systemic disease
   • IV: A child with severe systemic disease that is
       a constant threat to life
   • V: A moribund child who is not expected to
        survive without the procedure
Pre-procedural Criteria
   History and Physical/allergies/sedation hx
   Informed consent..for procedure and sedation/analgesia
    drugs
   NPO status
   Base-line vital signs
   Height and weight
   Adequate staffing
   Emergency equipment
Health Assessment
   Height / weight in kilograms
   Vital signs including blood pressure
   NPO status
   Allergies
   Current Medications (which may affect sedation level)
   Systemic diseases or genetic conditions
   Ability to intubated in the event of an emergency: size of
    jaw and ability to open mouth

Informed Consent
   a consent will need to be signed by a parent or legal
    guardian for the procedure & medications, & should be
    accompanied by a note in the medical record.
   What constitutes an ‗informed consent?‖
 NPO Guidelines


   Age         Duration of fasting      Duration of fasting
              (milk, formula, solids)     (clear liquids)
  Infants     6 hours for formula fed        2 hours

Children>3           8 hours                 2 hours
   years
NPO Guidelines
   Breast fed infants should be fasted for the normal interval
    between feeding
   When proper fasting has not been assured or in the case of a
    true emergency, ―the increased risks of sedation must be
    weighted against its benefits; and the lightest effective sedation
    should be used. In an emergency situation the child may
    require protection of the airway (intubation) before sedation‖,
    and emptying the stomach as much as possible.
TJC (The Joint Commission) Standards
   Procedure /Site Verification
   Marking the operative site
   Time out before procedure (Universal Protocol)
   All must be documented in the MR
BRN Scope of Practice
