Procedural Sedation: In A Nutshell Deb Updegraff, R.N., M.S.N. P.N.P. Clinical Nurse Specialist Pediatric Intensive Care 3S Intermediate Intensive Care LPCH
The Players • MD • RN • Patient
Levels of Sedation • Minimal Sedation (anxiolysis) • Moderate Sedation/Analgesia (formerly called conscious sedation) • Deep Sedation
American Association of Anesthesiologists: ASA RiskClassification ASA I - A healthy patient ASA II - A patient with mild systemic disease ASA III - A patient with severe systemic disease (limits activity but not incapacitating) ASA IV- A patient with an incapacitating systemic disease that is a constant threat to life ASA V- A moribund patient not expected to survive 24 hours with or without surgery
Pre-sedation Risk AssessmentAmpule • Allergies • Medications • Past Medical History • Last Meal • Events leading up to the need for sedation
Other Risks • Previous problems with anesthesia or sedation • Known difficult intubation • Cranial facial syndromes • Decreased airway protective reflexes • Obesity • GERD or problems with gastric motility
Equipment (SOAP) • Suction • Oxygen • Airway • Pharmacy
Monitoring Continuous: • ECG • O2 Sat Blood Pressure • Q 5 min for moderate to deep sedation • Q 15 min for others
Pharmacology: Selecting the MedsDepends on the Procedure and Patient History • LP • MRI • PICC placement • Central Line Placement • Bronchoscopy • Chest tube placement
Choice of Drugs • Analgesics • Narcotics • Fentanyl • Morphine • Ketamine • Sedation • Benzodiazepines • Midazolam • Lorazepam • Barbiturates • -Propofol
Fentanyl Bolus= 0.5-1.0 mcg/kg (MAY REPEAT Qq5-10MIN) Rigid Chest Syndrome Morphine - Bolus=0.05-0.1mg/kg (may repeat q5-10min) Histamine Release + Sedative and Hypnotic properties Narcotics Narcotics have both sedative and analgesic qualities
Midazolam Bolus=0.05-0.2 mg/kg Lorazepam Bolus=0.05-0.2 mg/kg Benzodiazepines Benzodiazepines have both sedative and Amnesic qualities NO Analgesic Properties
Ketamine Dissociative anesthetic: phencyclidine derivative (PCP) • IV - 0.5 to 2mg/kg • IM -3-4 mg/kg • + Analgesia/Sedation • Contraindicated Increased Intracranial Pressure Increased Intraoccular Pressure • Onset of action IV 1-2 minute • IM 3-10 minutes Can cause larygospasms and hallucinogenic emergent reactions.
Propofol • General Anesthetic Agent • NO Analgesic Properties • Advantages: • Rapid Onset and Emergence • Profound Sedation • Disadvantages: • Metabolic Acidosis • Severe SVR
Propofol - dosing Continuous Infusion 5-50 mcg/kg/hr Induction 2.5 – 3.5 mg/kg Over 20-30 seconds Repeat as child emerges
Reversal Agents Narcan: For Narcotic Reversal dose: 1-10mcg/kg IV push (1/10th of dose recommended for full reversal of narcotic poisoning) May need to repeat. OK: IV, IM, endotracheal Flumazenil: For Benzodiazepine Reversal- Can reverse benzo-induced respiratory depression and paradoxical excitatory reactions. dose: 0.01-0.02 mg/kg. May be repeated.
