Title: Moderate Conscious Sedation

  • Moderate Conscious Sedation

Upon completion of this learning module, the
nurse should be able to
  • 1. Define moderate conscious sedation.
  • 2. Identify nursing responsibilities before,
    during, and after a procedure involving moderate
    conscious sedation.
  • 3. Review medications commonly used in moderate

The purpose of this self learning study is to
review and update the nurse on moderate
conscious sedation.

  • A drug induced depression of consciousness during
    which patients respond purposefully to verbal
    commands, either alone or accompanied by light
    tactile stimulation.
  • No interventions are required to maintain a
    patent airway, and spontaneous ventilation is
  • Cardiovascular function is usually maintained.

Moderate Sedation is used for diagnostic,
therapeutic, and invasive procedures
  • Bone marrows
  • Bone reduction
  • EGD/colonoscopy
  • Chest tube insertion
  • Wound debridement
  • Heart lab procedures (ie. heart cath, TEE, EP
    studies, etc)
  • Minimally invasive surgical procedures
  • Cardioversion

Moderate Conscious Sedation does not apply to
  • Patients who are mechanically ventilated or whose
    cardiovascular and respiratory status are
    continuously monitored and documented in an ICU
    or PACU.
  • Patients who receive anxiolytic or analgesic
    agents that are routinely administered to
    alleviate pain and agitation.
  • Management of seizures.

Staff Qualifications
  • Conscious sedation is the responsibility of a
    licensed independent practitioner (LIP)
    privileged in moderate sedation.
  • LIP must be qualified and have the appropriate
    credentials as defined by the medical staff to
    manage patients at whatever level of sedation or
    anesthesia is achieved, either intentionally or
  • Sufficient numbers of qualified personnel are
    present to assist and document.

Physicians exempt from providing proof of
training for moderate conscious sedation are
intensivists, emergency medicine physicians, and
Moderate sedation is administered in the
following units
  • Operating Room
  • Pediatrics
  • Heart Lab
  • Oncology
  • Stepdown Units
  • Intensive Care Units
  • Outpatient services
  • Radiology
  • Pain Management
  • Emergency Department

  • Appropriate equipment for monitoring including
    heart, blood pressure, respiratory rate, and
    oxygenation using pulse oximetry
  • Cardiac arrest resuscitative equipment, reversal
    agents, and a code cart must be in the department
    where the procedure is performed
  • EKG is monitored as ordered by the physician for
    patients with heart disease or if arrhythmias are
    present or anticipated

Documentation of Moderate Sedation is completed
on form 202120
Post-procedure vital signs And Aldrette scoring
Post-procedure and discharge
Pre-procedure and Intra-procedure
Pre-Procedure ResponsibilitiesPhysician
  • History and Physical including airway assessment
  • Plan for moderate sedation and post procedure
  • Current medications
  • Documents NPO status
  • -Adults should be NPO for 4 hours
  • -Pediatric patients should have no
    solids or non-human
  • milk for 4 hours prior to the procedure
  • Obtains and documents informed consent for
    procedure and sedation

In extreme emergencies the physician may
determine it to be necessary to proceed with an
intervention without completing the above steps.
Pre-Procedure ResponsibilitiesHospital Staff
and Nursing
  • Verifies informed consent, HP, and reassessment
    has been done prior to procedure.
  • Verifies availability of emergency equipment,
    including O2 and suction.
  • Establishes venous access.
  • Assess patients VS, O2 sat, LOC, and Aldrete
    score and document on the moderate sedation flow
  • If the patient is an outpatient- complete
    outpatient nursing assessment record.

Intra-Procedure ResponsibilitiesPhysician
  • Assumes full responsibility for the
  • management of the procedure and sedation

Intra-Procedure ResponsibilitiesHospital Staff
and Nursing Role
  • Conducts and documents time out with physician
    present as well as the procedure team.
  • Monitors and documents the patients VS and O2
    sat every 5 minutes or more frequently prn.
  • Continuous assessment and documentation while
    assessing for changes in condition.

Post Procedure ResponsibilitiesPhysician
  • Documents a post procedure/anesthesia note,
    including pre and post procedure diagnosis,
    procedure findings, complications, blood loss or
    specimen removed, plan of care, and discharge

Post Procedure ResponsibilitiesHospital Staff
and Nursing Role
  • Monitors and documents the patients VS and O2
    sat immediately post procedure and every 15
    minutes post procedure until it is a minimum of
    30 minutes post narcotic/sedative dose, the
    patients Aldrete score is 12 or equivalent to
    his/her pre procedure Aldrete score, or by
    physician order

Aldrete Scoring System
Post Procedure ResponsibilitiesHospital Staff
and Nursing Rolecontinued
  • If the patient has received a reversal agent,
    monitor VS q 15 min. for 2 hours.
  • Notify the physician immediately if the patient
    doesnt meet the Aldrete score after 1 hour post
    procedure or if there is a significant variation
    in the patients physiological parameters.

Discharge Criteria
Discharge to hospital unit
Discharge from the hospital
  • Aldrete score of 12, or pre procedure status, or
    by physician order
  • Minimal nausea
  • At least 1 hour from last dose of narcotic,
    hypnotic, antiemetic
  • At least 2 hours from the last dose of reversal
  • Pain rated less than 4, equal to the pre
    procedure score, or tolerable for the patient
  • Accompanied by a responsible adult
  • Minimum 30 minutes since the last dose of
    narcotic or sedative
  • Aldrete score of 12, or pre procedure status, or
    by physician order

Medications used for Moderate Conscious Sedation
  • Individualize dose per recommendations.
  • Do not give by rapid or single bolus IV
  • Use small increments to achieve the appropriate
    level of sedation.
  • Titrate medication and dose to patient response.
    Expect to vary with age, physical status,
    concomitant medications.
  • Allow time for drug to circulate and to have an
    effect after each incremental dose.
  • Consider routine medications the patient has
    taken pre procedure they may potentiate and
    prolong the effects of the medications used for
    conscious sedation.

Drug IV Dosing Guidelines Onset, Peak, and Duration Comments
Morphine 2-4 mg. increments q 5 min. max dose of 10-20 mg. Peds 0.1-0.2mg/kg Onset- 1-3 min. Peak- 20 min. Duration- 2-4 hrs. Slower onset and longer duration than Fentanyl Histamine release assoc. with hypotension and itching
Fentanyl (Sublimaze) 1-3 mcg/kg, given in increments of 25-50 mcg max of 250 mcg Peds 1-2 mcg/kg total dose- given in increments up to 50 mcg max dose Onset- 1-2 min. Peak- 10-15 min. Duration- 30-60 min. Advantages include quick onset and short duration Causes less histamine release and less side effects as compared with morphine but 100 times more potent
Demerol (Meperidine) 10-25 mg increments max of 150 mg Peds 1-2 mg./kg. Onset 1-5min. Peak 1-3 hrs. Duration- 2-4 hrs. Nausea and vomiting common Risk of seizures
Drug IV Dosing Guidelines Onset, Peak, and Duration Comments
Versed (Midazolam) 1-3 mg increments every 2-3 min. Max of 5 mg. Peds 0.02-0.1 mg/kg IV or IM Give in increments total dose not to exceed 0.4mg/kg Onset- 1-3 min. Peak- 5-7 min. Duration- 20-30 min. (may need to redose) Quick onset and short duration Retrograde and antegrade amnesia
Valium (Diazapam) 1-2 mg increments Max of 10 mg. Peds 0.1-0.2 mg/kg Onset 1-5 min. Duration 2-8 hrs. Respiratory depression with narcotics Irritates veins Long duration
Reversal Agents
Drug IV Dosing Guidelines Onset, Peak, and Duration Comments
Narcan (Nalaxone) 0.1- 0.2 mg IV q 2-3 minutes prn Peds 0.005 -0.01 mg q 2-3 minutes prn Onset- 1-2 min. Duration- 30 min. when given IV Reverses narcotics only Reversal effect may not outlast narcotic Give slowly
Romazicon (Flumazenil) 0.2 mg over 15 seconds. After an interval of 45 seconds, a second dose of 0.2 mg may be given. Repeat at 60 second intervals until 1 mg. total. Peds 0.01mg/kg IV over 15 seconds, may repeat in 45 seconds Onset- 1-2 min. with peak effect within 10 min. Duration- 30-60 min. Reverses Benzodiazapines - ie. Versed - not narcotics Reversal may not out last sedative, monitor for 1 hr. after reversal
