Title/Description: Moderate Sedation and Anesthesia Care Department: Organization-wide Personnel: All Individuals Involved in Anesthesia Care Effective Date: 9/90 Revised: 3/94, 12/96, 4/00, 11/02, 02/03, 6/03, 12/04, 5/05, 1/06, 7/08, 3/12, 7/12, 12/14 PURPOSE To provide safe and consistent care for patients receiving sedation, whether moderate or deep, during therapeutic or diagnostic procedures, this would be in any setting, for any purpose, by any route, for minimal or moderate sedation. These guidelines are designed to provide specific recommendations for the safe care of patients during the delivery of medications for sedation by non-anesthesiologists during diagnostic and therapeutic procedures. Procedural Sedation (deep) may be performed with or without analgesia at the discretion of the Practitioner. DEFINITIONS 1. MINIMAL SEDATION (anxiolysis)- A drug-induced state during which patients respond normally to verbal commands. Although cognitive function and coordination may be impaired, ventilatory and cardiovascular functions are unaffected. 2. MODERATE SEDATION/ANALGESIA ( 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 adequate. Cardiovascular function is usually maintained. 3. DEEP SEDATION/analgesia- A drug-induced depression of consciousness during which patients cannot be easily aroused, but respond purposefully following repeated or painful stimulation. The ability to independently maintain ventilatory function may be impaired. Patients may require assistance in maintaining a patent airway and spontaneous ventilation may be inadequate. Cardiovascular function is usually maintained. 4. ANESTHESIA- Consists of general anesthesia and spinal or major regional anesthesia. It does not include local anesthesia. General anesthesia is a drug-induced loss of consciousness during which patients are not arousable, even by painful stimulation. The ability to independently maintain ventilatory function is often impaired. Patients often require assistance in maintaining a patent airway, and positive pressure ventilation may be required because of depressed spontaneous ventilation or drug-induced depression of neuromuscular function. Cardiovascular function may be impaired. 5. PROCEDURAL SEDATION-The administration of pharmacological agents to produce a sedated or dissociated state where the patient s lack of response and altered
cognition will aid in the performance of an unpleasant or painful procedure. Procedural Sedation and Analgesia is intended to result in a depressed level of consciousness but one that allows the patient to maintain airway control independently and continuously. The drugs, doses and techniques used are not likely to produce a loss of protective airway reflexes. 6. DISSOCIATIVE SEDATION-A trance-like cataleptic state induced by the dissociative agent ketamine and characterized by profound analgesia and amnesia, with retention of protective airway reflexes, spontaneous respirations, and cardiopulmonary stability. 7. LOSS OF PROTECTIVE REFLEXES-Loss of reflexes, including the inability to maintain a patent airway, handle secretions without aspiration or purposeful response to physical and/or verbal stimulation as a result of a systemically administered medication. 8. PRACTITIONER-Within the context of this policy, refers to a physician who is appropriately credentialed to provide Procedural Sedation. PROCEDURE I. Physician Responsibilities (credentials in sedation and anesthesia care) 1. Trained in professional standards & techniques to: a) Administer pharmacologic agents to predictably achieve desired levels of sedation; and b) Monitor patients carefully in order to maintain them at the desired level of sedation. c) Appropriate credentials to manage patients at whatever level of sedation or anesthesia achieved, either intentionally or unintentionally. d) Competency-based education, training & experience in evaluating patients prior to performing moderate or deep sedation & anesthesia and to include methods & techniques required to rescue those patients who unavoidably or unintentionally slip into a deeper-than desired level of sedation or analgesia including: - Practitioners who have appropriate credentials and are permitted to administer moderate sedation, are qualified to rescue patients from deep sedation and are competent to manage a compromised airway and to provide adequate oxygenation and ventilation. - Practitioners who have appropriate credentials and are permitted to administer deep sedation for procedures such as: dislocations & rapid intubation etc. are qualified to rescue patients from general anesthesia and are competent to manage an unstable cardiovascular system as well as a compromised airway and inadequate oxygenation and ventilation. - Qualified personnel are present during procedures using moderate or deep sedation to : * appropriately evaluate the patient prior to beginning moderate or
deep sedation and anesthesia; * provide the moderate or deep sedation and anesthesia; * perform the procedure; * monitor the patient; and * recover and discharge the patient either from the postsedation or postanesthesia recovery area 2. Physician will obtain informed consent in the discussion with the patient concerning Procedural Sedation, and make the determination of the eligibility of the patient for procedural sedation. The discretion of the physician is used on a patient by patient basis. Risks vs. benefits and complications will also be addressed by the M.D. II. Educational Requirements A. The following personnel are authorized to administer agents for moderate sedation: 1. Physicians or other licensed health care professionals who have appropriate credentials to administer sedation agents. This will be done by successful completion of appropriate training which should include residency training and/or continuing medical education in the following subject areas: a. IV Therapy b. Oxygen Delivery Devices c. Airway Management both basic and advanced d. Pharmacology of Sedation agents, and their antagonist including drug administration techniques, characteristics, and management of adverse reactions and over dosage, and other complications. e. Dysrhythmia recognition f. Basic Cardiac Life Support g. Organized program of study on moderate sedation 2. Anesthesiologists and CRNA s appropriately credentialed to administer sedation. 3. The practitioner s continued competency to provide Procedural Sedation will be re-evaluated as part of the Medical Staff recredentialing process. III. Locations where sedation may be administered 1. OR / PACU / OPS/GI Lab 2. ICU/.3500 3. Radiology, including CT & MRI Special Procedures 4. Cardiac Catherization Lab 5. Emergency Department
6. Bronchoscopy Lab Note: Monitoring and credentialing requirements must be met regardless of the location of such procedures. IV. Documentation All departments will use the Moderate Sedation documentation found in Sunrise under Flow Sheets and also under Document Tab in Sunrise under Nursing IntraOp and including the following: 1. Listing of current medications and dosages 2. Drug allergies, history of tobacco, alcohol, or substance abuse, drug reactions 3. Pregnancy status is noted, if applicable 4. Time and nature of last oral intake-recent food intake is not a contraindication for administering Procedural Sedation but should be considered in choosing the depth and target level of sedation. 5. Overall physical status according to the American Society of Anesthesiologists (ASA) ASA Class 1: A normal, healthy patient ASA Class 2: A patient with mild systemic disease (ex: Asthma, controlled diabetes) ASA Class 3: A patient with severe systemic disease (ex: moderate COPD, stable angina) ASA Class 4: A patient with severe systemic disease that is a constant threat to life (ex: unstable angina, DKA) ASA Class 5: A Moribund patient who is not expected to survive without the operation. ASA Class 6: A declared brain dead person whose organs are being removed for donor purposes: 6. Procedural Sedation for patients- falling into classes III, IV, V, or VI is generally not recommended. Should Procedural Sedation be deemed necessary by the attending physician for this class of patient, it should be performed in consultation with the patient s primary physician and/or anesthesiologist. 7. Emergency (E) - The Suffix E is used to denote the presumed poor physical status of any patient in one of these categories that is operated on as an emergency. 8. Establish a patent intravenous line to be maintained from the beginning of the procedure until post-procedure discharge criteria are met (NO HEPLOCK). Intavenous line may be established on an as needed basis if only giving sedation medication by mouth. 9. Authorizing the administration of the sedative within the recommended moderate sedation dosage guidelines.
Note: An RN or other licensed healthcare provider may conduct the evaluation/assessment, but final responsibility for authorization to administer sedative rests with the physician. 10. Procedure Performed 11. Baseline and on going vital signs, location, 02 SAT, and cardiac rhythm strip 12. IV therapy, including fluid type, amount, and infusion rate. 13. Medication name, route, dose, time, and person administering. 14. Complications or drug side effects and their management. 15. Status of the patient upon conclusion of the procedure. 16. For Outpatients, any of the following methods of documentation by the M.D. will suffice: a) A Short Form H & P (dictated or written w/in 30 days-update day of surgery unless dictated the day of surgery) b) An H & P from the referring physicians office c) The emergency department history & physical evaluation
