The IACUC will determine if further justification as prolonged restraint is required on a case-by-case basis.&nbsp; As the duration of restraint increases, a concomitant increase in attention should be given to alternatives to restraint, to the endpoint criteria for the restraint, and to monitoring the health and well-being of the restrained animal. The restraint must be described based on the species, scientific rationale and justified in the Exceptions section of the AVAU.&nbsp;<\/p>\n\n\n\n<p>Prolonged restraint is subject to the following considerations:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Prolonged restraint must be the minimum required to accomplish the research objectives.&nbsp; Alternatives to physical restraint should be considered.<\/li>\n\n\n\n<li>A description of the restraint device, duration of restraint, and a plan for routine monitoring must be included in the AVAU, including clinical signs of pain and\/ or distress that will be monitored and the amount of time that will be allowed to elapse before intervention if distress develops.<\/li>\n\n\n\n<li>For Agriculture species, restraint that restricts movement&nbsp; (i.e. chutes, stocks, or headlocks) must be included in the protocol with a description of rest periods and monitoring. The use of farrowing crates or pens must align with the Ag guide. Animals placed in restraint devices should be acclimated and given positive reinforcement&nbsp; training to adapt to the equipment and personnel as appropriate for the species. These details are to be included in the protocol and any animals that fail to adapt must have criteria for temporary or permanent removal from the study.&nbsp;<\/li>\n\n\n\n<li>Veterinary care must be provided if lesions, illness, or severe behavioral changes indicating distress are observed. The Attending Veterinarian (or designee) has the authority to terminate the restraint procedures at any point should there be signs of complications compromising the animal\u2019s wellbeing.<\/li>\n\n\n\n<li>It is the responsibility of the Principal Investigator to ensure that the animals are monitored at appropriate intervals by adequately trained individuals. Personnel must be trained in restraint procedures, equipment, and monitoring.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Restraint Stress<\/h3>\n\n\n\n<p>Restraint stress such as prolonged restraint in non-acclimated animals can be approved with justification as a category E procedure if it is essential for achieving the research objectives.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">References<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>National Research Council. 2011.&nbsp;<a href=\"https:\/\/doi.org\/10.17226\/12910\" target=\"_blank\" rel=\"noreferrer noopener\">Guide for the Care and Use of Laboratory Animals: Eighth Edition<\/a>.

The method of animal restraint used to achieve a particular objective in an experimental protocol should be chosen to minimize distress to the animal. Restraint is defined as limiting or restricting the normal physical movement of an awake, non-anesthetized, non-sedated animal. Physical restraint is the use of more than momentary manual or mechanical means to limit some or all of an animal\u2019s normal movement for the purpose of examination, collection or samples, drug administration, therapy or experimental manipulation. Restraint devices should not be used simply as a convenience in handling or managing animals. Restraint devices should be suitable in size, design, and operation to minimize discomfort, pain, distress and the potential for injury to the animals and staff.\u00a0 Mechanisms of restraint could include tethers, slings, DecapiCone restrainer, cylinder restrainer, metabolism cages\/stalls, or any other device that limits animal movement.<br><br>All persons involved with the care and\/or use of animals in research and\/or teaching at the University or wildlife studies, including, but not limited to Principal Investigators, researchers, Animal Handlers, and students.\"}","ncst_content_audit_freq":"","ncst_content_audit_date":"","ncst_content_audit_display":false,"ncst_backToTopFlag":"","footnotes":""},"tags":[],"class_list":["post-1255","page","type-page","status-publish","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.1.1 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Use of Restraint in Vertebrate Animal Studies - Research Administration and Compliance<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/research.ncsu.edu\/administration\/compliance\/research-compliance\/iacuc\/iacuc-procedures-and-guidance\/restraint-in-vertebrate-animal-studies\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Use of Restraint in Vertebrate Animal Studies - Research Administration and Compliance\" \/>\n<meta property=\"og:description\" content=\"Guidance Any restraint that is part of the scientific objectives of the study must be described in the protocol.
