ASTM Color Guidelines
Anesthesia professionals frequently encounter high-pressure situations where they must simultaneously manage various medications, syringes, alarms, and fluctuating patient needs. In these environments, even small improvements in medication identification can help reduce cognitive workload and improve safety.
Despite strategies like the Five Rights of Medication Administration and National Performance Goals, system complexity and medication variety continue to cause errors. There is no patient care delivery area that highlights these challenges more than anesthesia. It is one of the few areas in healthcare with no secondary verification of medication administration, yet it also has the highest number of administered medications, most of which are high-alert medications. To minimize these risks, clinicians rely on various identification methods, including ASTM color guidelines. This guide explores how these protocols can improve safety across your operations.
Key Takeaways
- Standardized visual identification. ASTM color guidelines provide standardized visual identification for anesthesia medication classes. Each drug class is assigned a specific color to help clinicians distinguish medications more quickly during procedures.
- A supplement, not a substitute. Color should never be the only method used to identify a medication. Providers should always verify the drug name, concentration, and other label information before administration.
- Reduces variability across care settings. Consistent labeling practices help improve communication and medication identification in operating rooms, labor and delivery, ambulatory surgery centers, and other procedural areas.
- Layered safety strategy. Combining ASTM colors with clearly printed drug names, Tall Man lettering when appropriate, barcode technology, and standardized labeling procedures creates a layered medication safety strategy.
- Implementation takes more than labels. Organizations should establish standardized labeling policies, educate staff, and routinely evaluate compliance to maximize the safety benefits of ASTM color guidelines.
What Are ASTM Color Guidelines?
ASTM International is a global leader in developing standards for over 150 different industries including healthcare and pharmaceuticals. ASTM standards are developed through the expertise and judgment of members in each respective industry. In healthcare, the guidelines apply to each unique drug classification, which is assigned a specific color by the ASTM. For example,
- Blue labels — opioids
- Fluorescent red — neuromuscular blockers
- Yellow — induction agents
- Orange — tranquilizers
- Violet — vasopressors
- Green — anticholinergics
Why Are ASTM Color Guidelines Important?
ASTM color guidelines aid in the safe dispensing of user-prepared medication syringes. For example, when a patient requires an opioid, the clinical staff knows the syringe should contain a blue colored label. This visual cue offers an additional means to distinguish between various types of anesthesia, which is especially important in the operating room and intensive care units, where distractions can present obstacles to the clinical staff. To manage these distractions, some tasks that are repeatedly performed may rely on working memory. Without the color cues, providers may unintentionally use less reliable options such as size or location.
When the clinical staff operates in a high stress situation or is fatigued, color-coding can help to simplify complex tasks. It offloads mental processing from the working memory so clinicians can dedicate their focus to active patient monitoring and care rather than decoding labels.
It's important to note that colors serve as an important layer within a broader medication safety system. Providers should always confirm the drug name, concentration, and other critical label information before administration.
Challenges With Using ASTM Color Guidelines
Our brains are better at storing and retrieving information when we use multiple senses. But not when the information we're retrieving is inconsistently presented. Although ASTM color guidelines have the potential to improve medication administration accuracy, the lack of a universally standardized system enforced by accrediting organizations remains a significant challenge. The inconsistencies can lead to misidentification of medication syringes, medication errors, and adverse patient outcomes.
In addition, with multiple high-risk medications within the same drug class, an over-reliance on one variable, like color, when selecting a syringe poses significant error risks.
How to Use ASTM Color Guidelines Effectively
While ASTM color guidelines are valuable, they are not intended to be the sole method for identifying and distinguishing medications. But they are effective when incorporated into the medication labeling process. For example, an anesthesia label that includes the drug name, concentration, time and expiration date, combined with the ASTM color classification, incorporates the essential checks that should occur with each patient and the color cue. Collectively, they work in concert to elevate medication safety.
Use ASTM Color Guidelines with LASA Labels
Another area that remains an ongoing challenge is confusion over similarly named drugs. The ISMP recently updated their confused drug names list, which now includes over 150 different items. For example:
- Dobutamine vs. Dopamine — DOBUTamine vs. DOPamine
- Clonidine vs. Clozapine — cloNIDine vs. cloZAPine
- Vincristine vs. Vinblastine — vinCRIStine vs. vinBLAStine
In practice, Tall Man lettering appears on a range of critical communication tools including medication labels, electronic health record systems (EHRs), pharmacy dispensing software, IV bags, and packaging. When used consistently, it significantly enhances visibility and reduces confusion, especially in environments with high-alert medications.
Because similar-sounding drugs often fall into different drug classifications, Tall Man and Look-Alike Sound-Alike flags, which incorporate the ASTM color guidelines, serve to alert the medical staff and help prevent mistakes.

Healthcare organizations have incorporated barcode technology into their medication management processes to provide an additional level of verification before medications reach the patient. But when combined together, barcode verification and standardized anesthesia labels can further reduce the risk of selecting or administering the wrong medication.
In the anesthesia environment, providers often prepare and label syringes before procedures begin, then manage multiple medications simultaneously throughout the case. During busy procedures, visual identification remains essential because clinicians need to distinguish medications quickly without interrupting patient care. Clearly printed drug names, concentrations, preparation dates, expiration times, and standardized color classifications allow providers to rapidly identify syringes. Barcode systems provide an additional layer of safety by supporting documentation and medication verification.
ASTM Color Guidelines Are Consistent With Accreditation 360 Standards
Accreditation 360 and the new National Performance Goals cite effectively managing medications as a key area to improve patient safety and care quality.
The Standard — Label all medications, containers (syringes, cups, basins), and solutions on and off the sterile field. Even if a syringe is filled in the sterile area but kept on a separate table, or if a medication is prepared in the pharmacy and brought to the room, it must be labeled.
The Challenge — Adverse Drug Events (ADEs) affect nearly 5% of hospitalized patients. Unlabeled or conventionally labeled containers (like syringes or basins) are common culprits in preventable errors.
Anesthesia & Drug Labels that follow ASTM color guidelines simplify the medication labeling process and serve as an important visual cue. When combined with LASA labels, they provide an important mental check that can help prevent medication errors.
Implementing ASTM Color Guidelines
Simply selecting color-coded labels is only the first step. To maximize their effectiveness, organizations should implement ASTM color guidelines as part of a standardized medication labeling process that is consistently followed throughout every anesthesia service area.
Standardize Labels Across All Perioperative Settings
Use the same labeling conventions in operating rooms, critical care, labor and delivery, procedural areas, ambulatory surgery centers, and post-anesthesia care units. Consistency reduces confusion when staff move between departments or assist in unfamiliar areas.
Include Complete Medication Information
Every anesthesia label should clearly identify the drug name, concentration, preparation date and time, expiration information, and any additional information required by facility policy. ASTM colors should reinforce this information.
Use Multiple Visual Safety Cues
ASTM color classifications, Tall Man lettering for look-alike/sound-alike medications, and large, legible typography each provide unique visual cues that help clinicians quickly distinguish medications under demanding conditions.
Develop Standardized Preparation and Labeling Procedures
Establish clear policies for labeling medications, who is responsible for labeling, and how to apply labels before placing syringes on the sterile field.
Educate Staff Regularly
Provide ongoing education for anesthesia providers, nurses, pharmacists, and new employees to reinforce the purpose of ASTM color guidelines and the importance of verifying every medication before administration.
Evaluate Compliance Through Periodic Audits
Routine observations and medication safety reviews help identify inconsistencies, reinforce best practices, and support continuous improvement efforts.
Ultimately, to facilitate medication syringe identification, color-coded labels require a standardized guideline with strict practice enforcement. Enforcing this standard across anesthesia service areas will enhance safety. Further, simplifying processes will likely lead to improved safety outcomes.
