Randomized Controlled Trial Comparative Study
Thoracic paravertebral block versus thoracic epidural analgesia for post-operative pain control in open pancreatic surgery: A randomized controlled trial.
The purpose of this study was to compare the efficacy of bilateral ultrasound guided thoracic paravertebral catheters to a thoracic epidural after open pancreatic surgery. ⋯ The use of thoracic paravertebral catheters provided comparable analgesia and less modality related adverse events when compared to a thoracic epidural in patients undergoing open pancreaticoduodenectomy.

There are few patient-reported outcomes routinely used that capture frequency and interference of different pain-related symptoms on a single scale. The purpose of this study was to describe the development and initial validation of the new Multidimensional Symptom Index (MSI). ⋯ This article presents the development and psychometric properties of a new measure of pain and related symptom frequency and interference. This measure could aid clinicians in establishing clinically relevant pain phenotypes for screening, prognosis and treatment decisions.

Psychosocial factors and responses to injury modify the transition from acute to chronic pain. Specifically, posttraumatic stress disorder (PTSD) symptoms (reexperiencing, avoidance, and hyperarousal symptoms) exacerbate and cooccur with chronic pain. Yet no study has prospectively considered the associations among these psychological processes and pain reports using experience sampling methods (ESMs) during the acute aftermath of injury. This study applied ESM via daily text messaging to monitor and detect relationships among psychosocial factors and postinjury pain across the first 14 days after emergency department (ED) discharge. ⋯ Daily hyperarousal symptoms predict same-day pain severity over the acute postinjury recovery period. We also demonstrated feasibility to screen and identify patients at risk for pain chronicity in the acute aftermath of injury. Early interventions aimed at addressing hyperarousal (e.g., anxiolytics) could potentially aid in reducing experience of pain.

Comparative Study
Comparing N-PASS and NIPS: Improving Pain Measurement in the Neonate.
Proper assessment of pain is essential to allow for safe and compassionate care of infants in the neonatal intensive care unit (NICU). The Neonatal Infant Pain Scale (NIPS) used in an urban level IV NICU addresses acute pain but may not adequately measure chronic neonatal pain. ⋯ Further research evaluating guided management of acute and chronic pain scores on the N-PASS would aid hospital policies on therapies for neonatal pain.

Generalized hyperalgesia and impaired pain modulation are reported in chronic low back pain (LBP). Few studies have tested whether these features are present in the acute phase. This study aimed to test for differences in pain presentation in early-acute LBP and evaluate the potential contribution of other factors to variation in sensitivity. ⋯ Four subgroups with distinct features were identified: "high sensitivity," "low CPM efficacy," "high sensitivity/low CPM efficacy," and "low sensitivity/high CPM efficacy." Various factors such as sleep and alcohol were associated with each pain measure. Results provide evidence for generalized hyperalgesia in many, but not all, individuals during acute LBP, with variation accounted for by several factors. Specific pain phenotypes provide candidate features to test in longitudinal studies of LBP outcome.
