The Modified Behavioral Pain Scale (MBPS) was designed to assess procedural pain in infants and is considered valid for assessing immunization pain. The aim of this study was to assess the practical and psychometric properties of the MBPS when applied to other commonly performed procedures. Twenty-six clinicians independently applied the MBPS scale to segments of video collected from 100 infants and children aged 6 to 42 months undergoing 1 of 4 procedures in the emergency department. ⋯ Finally, 28% of scores changed after the second viewing of a video segment. The MBPS appears reliable and sensitive to procedural pain when applied by clinicians. Results question the capacity of the scale to differentiate between pain- and nonpain-related distress, the feasibility of this scale, and the appropriateness of item descriptors for medical procedures.

Observational Study
Predicting outcomes of acute low back pain patients in emergency department: A prospective observational cohort study.
Low back pain (LBP) is a common complaint among patients presenting to emergency department (ED) in Singapore. The STarT Back Screening Tool (SBT) was recently developed and validated for triage of LBP patients in primary care settings. This study aimed to investigate whether the SBT could provide prognostic information for long-term outcomes of acute LBP patients visiting the ED, who might benefit from appropriate and timely management at an earlier stage. ⋯ In the model, SBT total score and 6-week pain score were significantly associated with 6-month pain score (P < .05) with respective coefficients of 0.125 and 0.500. The model explained 40.1% of the variance for 6-month pain score. This study demonstrated that the multiple linear regression model showed predictive performance in determining long-term outcomes for acute LBP patients presenting to the ED.

The aim of this study was to evaluate whether standardized responses to nociceptive pain, assessed with the revised Nociception Coma Scale (NCS-R), were correlated with the outcomes of patients with unresponsive wakefulness syndrome (UWS) 6 months after admission to a rehabilitation department. We recruited 24 consecutive patients with UWS. Patients' consciousness levels were assessed with the revised Coma Recovery Scale (CRS-R) at admission and 6 months later, and their CRS-R scores were correlated with the NCS-R scores at admission. ⋯ Patients with and without consciousness improvement after 6 months showed no significant difference in the NCS-R total score and sub-scores at admission (P values > 0.05). In conclusion, the correlation between NCS-R and CRS-R scores at admission suggests that the standardized assessment of pain parallels patients' levels of consciousness, and may be helpful in the clinical evaluation of patients with UWS. Pain response assessed with the NCS-R was not related to the 6-month outcomes of patients with UWS.

Randomized Controlled TrialEfficacy and Safety of Lidocaine Infusion Treatment for Neuropathic Pain: A Randomized, Double-Blind, and Placebo-Controlled Study.
Lidocaine infusion therapy (LIT) is an effective treatment for relieving neuropathic pain (NeP). However, it remains unclear whether pain relief can be sustained through repeated lidocaine infusions. This study aimed to determine whether repeated intravenous administration of low-dose lidocaine could provide prolonged pain relief in patients with specific NeP conditions. ⋯ This study was registered at ClinicalTrials.gov, identifier NCT02597257.

Randomized Controlled TrialDexamethasone as an Adjuvant to Femoral Nerve Block in Children and Adolescents Undergoing Knee Arthroscopy: A Prospective, Randomized, Double-Blind, Placebo-Controlled Trial.
Perineural dexamethasone has been demonstrated to extend postsurgical analgesia after peripheral nerve blockade in adults. The mechanism of action of dexamethasone as a regional anesthetic adjuvant is unclear as intravenous dexamethasone has been shown to have similar analgesic efficacy as perineural dexamethasone. The efficacy of perineural dexamethasone has not been previously explored in the pediatric population. ⋯ This study was registered at ClinicalTrials.gov, identifier NCT01971645.
