Association for Radiologic & Imaging Nursing Position Statements (Updated Februay 2016)

Use of Capnography for Patients Who Receive Moderate Sedation/Analgesia

ARIN endorses the routine use of capnography for all patients who receive moderate sedation/analgesia during procedures in the imaging environment.  This position is based on an extensive literature review demonstrating technical superiority and cost advantages with capnography use.

Bariatric Patient Safety in the Imaging Environment

The obese patient presents specific challenges within the imaging department because of the constraints of imaging technology design, weight limits, positioning limitations; potential respiratory depression related to sedative and analgesia medications combined with cardiac and respiratory system factors unique to the obese patient; and availability of instruments of appropriate length to target the identified lesion. Screening may reveal that anesthesia may be the most appropriate level of care to maximize safe and successful outcomes.

Contrast Medium Administration to Breast Feeding Mothers

Occasionally, contrast agents (either iodinated or gadolinium based) are indicated for an imaging study on a breastfeeding mother. The patient and the physician may be concerned about contrast media being excreted into breast milk and the contrast media exposure to the infant.

Nursing Leadership and Performance Position Statement

Imaging nurses influence patient care in a variety of settings and nursing roles. Imaging nurses are involved in the assessment, care planning, and direct care of patients before, during, and after diagnostic and therapeutic imaging procedures. Imaging nurses promote high quality patient care in those environments.

Patient Safety in the Imaging Setting

Healthcare professionals in the medical imaging setting face unique challenges to ensure patient safety. Broad process and systems interventions are required to ensure that patient safety initiatives are carefully developed, implemented, and maintained ensuring a culture of safety (Emergency Nurses Association, 2005). The Association for Radiologic and Imaging Nursing (ARIN) is dedicated to the success of research, education, and implementation of evidence-based measures that ensure the well-being of patients receiving care and treatments in the imaging setting. In addition, the core purpose of ARIN is to foster the growth of nurses who advance the standard of care in the imaging environment.

Role of the Imaging Registered Nurse in Patients Undergoing Sedated Procedures

The Imaging Registered Nurse plans, coordinates, and delivers nursing care for patients across the life span who are going to receive sedation and analgesia while undergoing a radiological procedure. The purpose of sedation and analgesia is to relieve anxiety, discomfort or pain and diminish memory of the event and to facilitate the best results. Possessing clinical knowledge, sound judgment and critical thinking skills based on scientific principles the nurse plans and implements nursing care to address physical, psychological and spiritual responses of the patient undergoing a radiological procedure. The nurse is responsible for the patient outcomes resulting from the nursing care provided during the radiological procedure.

The Registered Nurse in the Imaging Setting

The imaging nurse uses evidence-based practice to provide quality nursing care for patients in the imaging setting. The nurse is knowledgeable in meeting the physical, psychological, cultural, and educational needs of patients.

ARIN Clinical Practice Guidelines (Updated May 2015)


Vertebroplasty is a percutaneous procedure performed to treat painful vertebral compression fractures.

Universal Protocol and Verification for Invasive and/or High Risk Procedures in Imaging

The Safety in America group and The Joint Commission have set forth guidelines for the safe care of patients undergoing invasive procedures. The Joint Commission’s Universal Protocol for Preventing Wrong Site, Wrong procedure, Wrong Person Surgery™ was developed to ensure that these guidelines become a part of our culture and practice.

Moderate Sedation and Analgesia

Moderate Sedation and Analgesia medications are frequently administered by Imaging Nurses. Moderate Sedation and Analgesia is defined as a drug‐induced depression of consciousness during which patients respond purposefully to verbal commands, either alone or accompanied by light tactile stimulation.

Handoff Communication Concerning Patients Undergoing a Radiological Procedure with General Anesthesia

The Joint Commission (JC) has identified that ineffective communication has been the root cause for sentinel events compromising safe patient care. To that end, National Patient Safety Goal (NPSG) 2E requires a “handoff” communication when care is transferred from one clinician to another.

Contrast Media Administration to Pregnant or Potentially Pregnant Patients

Studies of contrast (iodinated and gadolinium-based) in pregnancy are limited. Effects of contrast on the human embryo or fetus are unknown. It must be assumed that all contrast media cross the blood-placenta barrier into the fetus. No data are available to assess the rate of clearance of contrast agents from the amniotic fluid. It is not possible to state with certainty whether contrast agents present a risk or pose no risk to the fetus. Patients of child-bearing potential should be screened for the possibility of pregnancy.

Contrast Extravasation

Extravasation of contrast medium can occur during hand or power injection. Iodinated contrast media are toxic to surrounding tissues, particularly skin. Some patients will experience stinging or burning, but other patients will have little to no immediate discomfort.

Metformin Therapy and Lactic Acidosis Risk

Metformin is an oral antihyperglycemic agent used to treat patients with type II diabetes mellitus. The most significant adverse effect of metformin therapy is the development of metformin-associated lactic acidosis in the susceptible patient. Although the incidence of metformin-associated lactic acidosis is rare, the mortality is high: 50% of patients with metformin-associated lactic acidosis die. Therefore, metformin and drugs containing metformin should be withheld temporarily for patients undergoing radiological studies using intravenous (IV) iodinated contrast.

Iodinated Gastrointestinal Contrast Medium

Barium sulfate contrast media or aqueous contrast agents may be indicated in fluoroscopic or computed tomography applications. These agents can be given by mouth, feeding tube, or enema, as indicated for the appropriate study.

Contrast Associated Nephrotoxicity

Renal failure due to contrast media has been reported to be the third most common cause of in-hospital renal failure, after hypotension and surgery. Transient renal effects are seen after intravascular contrast and may be due to renal hemodynamic changes or direct tubular toxicity of the contrast media. Patients with normal renal function are at extremely low risk for contrast-associated nephrotoxicity.

Guidelines for Personnel Dealing with Chemotherapy/Cytotoxic Medications

Medications used in the treatment of cancer are considered hazardous to healthcare workers. The term “hazardous” describes medications that need special handling because of health risks that may result from exposure. These risks are a result of the inherent toxicities of the medications.

Informed Consent for a Radiology Procedure

Patient consent is required at various times in health care delivery. Radiology procedures requiring consent include but are not limited to: 1) invasive procedures such as a biopsy, drainage and/or placement of a drainage catheter, 2) angiograms or venograms, 3) vascular access catheter placement and 4) moderate sedation for a procedure.
