and Sedatives Last Reviewed: 7-5-2017

Institutional Animal Care and Use Committee (IACUC) Standard Operating Procedure
USING ANALGESICS, ANESTHETICS, AND SEDATIVES
1. Purpose
This procedure describes the recommended use of analgesics, anesthetics, and sedatives in animals used for research and teaching on approved Institutional Animal Care and Use Committee (IACUC) protocols. Federal regulations mandate that animals undergoing potentially painful procedures be given anesthesia and/or analgesia to minimize their pain and distress. Exceptions to this are only permitted when scientific justification is included in the IACUC protocol and is approved by the ISU IACUC.
2. Scope
This SOP is applicable to all ISU staff, research investigators, and technicians who provide care and/or use animals that will receive any analgesics, anesthetics, or sedatives. ISU staff, research investigators, and technicians are expected to understand the content of SOPs related to their work responsibilities.
This policy is applicable to individuals from all colleges performing research-related procedures on animals. Veterinary medical and animal care procedures are outside the scope of this policy when they are unrelated to the research project and when they are performed to improve animal health or well-being or to treat an illness or injury under the direction of the Attending Veterinarian or designee.
3. General Requirements
The Attending Veterinarian (AV) has the authority to ensure the provision of adequate sedation, analgesia, or anesthesia as mandated by the Animal Welfare Act and related animal care regulations. The AV or designee should therefore be directly involved in the selection of appropriate agents during protocol development. The procedures within this SOP for using analgesics, anesthetics, and sedatives are intended to assist investigators in their use of animals for research or teaching. Experimental design or special circumstances may dictate modification of dose levels or agents/methods

outlined herein. We strongly encourage the use of pre-operative, intra-operative, and post-operative analgesics in ALL recovery surgical procedures. The ISU Institutional Animal Care and Use Committee will rely on the procedures outlined in this SOP when reviewing animal protocols and may request explanations or justifications for substantial deviations. Intravenous barbiturates (i.e., thiopental, pentobarbital) for use as an anesthetic should be administered by giving 1/3–1/2 of the total calculated dose as a bolus, followed by titration of the remaining volume to effect, if needed. Special considerations apply to late term fetal and neonatal altricial rodents (e.g., rats and mice between E15 and P7). Dosage intervals listed on tables are single doses unless otherwise noted. A veterinarian should be consulted to assist in determining the frequency and amount of drug needed for repeated dosing. Investigators who use controlled anesthetic or analgesic agents must comply with the special storage and record keeping requirements. When issued a controlled substance as defined by the U.S. Department of Justice Drug Enforcement Administration, the PI responsibilities are to • keep the substance in a secure, locked location when not in use; • record usage of the substance (see Table below); • maintain the record of usage for 3 years from the date that a substance is completely used or returned to LAR; • return outdated substances and Records of Usage to LAR. The ISU IACUC has a controlled substance record template available. Environmental Health and Safety is available for consultation about safety of the agent prior to use. Investigators who use anesthetic gases must follow the IACUC SOP ‘Anesthetic Gas Usage Safety Precaution’
4. Procedure
A. Follow the analgesia regimens in Appendix 1 for commonly used species at Iowa State University.
B. For species or agents not listed please contact LAR at [email protected] for a consultation to identify the appropriate analgesics and anesthetics.

5. Roles and Responsibilities
ISU Attending Veterinarian or Designee
Be involved in the selection of appropriate agents during protocol development.
Investigators If the anesthetic or analgesic used is a controlled substance, follow the required special procedures for storage and record keeping—see the IACUC Controlled Substance Record Template for details. Review proper handling procedures with Environmental Health and Safety prior to the use of specific agents. Responsible for following the procedures described in this guide and the final approved IACUC protocol.
6. Definitions
A. Analgesia: loss of sensitivity to painful stimulation without loss of consciousness. B. Anesthesia: loss of feeling or sensation, which is often accompanied by loss of
consciousness. C. Local anesthesia: the loss of sensation to a section of the body. D. General Anesthesia: unconsciousness with adequate analgesia and muscle relaxation to
allow for surgery. E. Sedation: a mild degree of central depression in a conscious but calm animal also
referred to as tranquilization. F. Common Abbreviations
1. IM: intramuscular 2. IP: intraperitoneal 3. IV: intravenous 4. SQ or SC: subcutaneous 5. PO: per os – means to be given by mouth or orally 6. q: every 7. bid: give medication twice a day 8. sid: give medication once a day 9. qxh or qxd: once every x hours or once every x days
