Optimizing Neonatal Care: The Power of N-PASS in Assessing Pain, Agitation, and Sedation

Author: Brian Halse

In the world of neonatal care, precision and sensitivity are paramount. Infants are not able to voice concerns, fears or pain and adults are not particularly good at guessing at the needs of a neonate.

The Neonatal Pain, Agitation, and Sedation Scale (N-PASS) is an essential tool designed to help healthcare professionals assess and manage these critical aspects in neonates, particularly in intensive care and critical care retrieval settings.

Understanding the N-PASS Tool

The N-PASS tool is structured around five key domains:

1. Cry/Irritability: The quality and characteristics of an infant’s cry can reveal much about their discomfort.

2. Behavioral State: Observing an infant’s level of alertness and responsiveness gives insight into their well-being.

3. Facial Expression: Tiny expressions—grimacing, furrowing of the brow—can be subtle yet significant indicators of pain.

4. Extremity Tone: Changes in muscle tone and posture signal potential agitation or discomfort.

5. Vital Signs (HR, RR, BP, SaO2): Physiological indicators like heart rate and blood pressure provide a crucial baseline for assessing distress.

Scoring and Clinical Application

Each domain is scored on a scale from 0 to 2, giving a total score out of 10, which helps guide pain and sedation management. Regular assessments and triggered evaluations ensure the infant’s comfort and help in making timely adjustments to treatment plans. The N-PASS is not just about numbers—it’s about interpreting those scores within the context of the infant’s needs.

For instance, in premature neonates, the scoring is adjusted to account for their unique physiological challenges, acknowledging that even without overt signs, these infants may still experience significant pain.

We make an adaption for premature neonates because they are not able to physiologically or physically always show pain despite feeling it.

• <28 weeks the infant already scores a 3 on the pain score
• 29-31 weeks the infant scores 2 on the pain score
• 33-35 weeks the infant scores 1 on the pain score

Making Informed Decisions

When using the N-PASS, the first question should always be: what is the intention for the neonate? If sedation is the goal but the infant still shows signs of agitation, further action is needed. Conversely, a reduction in pain score from +4 to +2 can signal success in pain management.

Benefits of N-PASS

The N-PASS isn’t just a scoring tool; it’s a pathway to enhanced patient outcomes:

? Improved Comfort: By accurately assessing and managing pain, we can significantly improve neonatal comfort and well-being.

? Optimized Care: Tailoring pain and sedation management to the infant’s specific needs ensures the highest quality of care.

In summary, the N-PASS is a critical tool that enables us to better understand and respond to the needs of our most vulnerable patients, ensuring they receive the care they deserve.
