Introduction: A consistent approach to pain assessment for
patients admitted to intensive care unit (ICU) is a major difficulty for health
practitioners due to some patients’ inability, to express their pain verbally. This study
aimed to assess pain behaviors (PBs) in traumatic brain injury (TBI) patients at different
levels of consciousness.
Methods: This study used a repeated-measure, within-subject
design with 35 patients admitted to an ICU. The data were collected through observations
of nociceptive and non-nociceptive procedures, which were recorded through a 47-item
behavior-rating checklist. The analyses were performed by SPSS ver.13 software.
Results: The most frequently observed PBs during nociceptive
procedures were facial expression levator contractions (65.7%), sudden eye openings
(34.3%), frowning (31.4%), lip changes (31.4%), clear movement of extremities (57.1%),
neck stiffness (42.9%), sighing (31.4%), and moaning (31.4%). The number of PBs exhibited
by participants during nociceptive procedures was significantly higher than those observed
before and 15 minutes after the procedures. Also, the number of exhibited PBs in patients
during nociceptive procedures was significantly greater than that of exhibited PBs during
the non-nociceptive procedure. The results showed a significant difference between
different levels of consciousness and also between the numbers of exhibited PBs in
participants with different levels of traumatic brain injury severity.
Conclusion: The present study showed that most of the
behaviors that have been observed during painful stimulation in patients with traumatic
brain injury included facial expressions, sudden eye opening, frowning, lip changes, clear
movements of extremities, neck stiffness, and sighing or moaning.
