Randomized Controlled Trial Multicenter Study
Long-term safety and effectiveness of tanezumab as treatment for chronic low back pain.
A noncontrolled, randomized, multicenter study (NCT00924664) evaluated long-term safety and effectiveness of tanezumab in patients with chronic low back pain following a randomized placebo- and active-controlled parent study that evaluated analgesic efficacy. Patients were randomized to tanezumab 10mg (n=321) or 20mg (n=527) administered at 8-week intervals via 3 intravenous injections followed by 4 subcutaneous injections. Effectiveness analyses included change from parent study baseline in Brief Pain Inventory Short Form, Roland Morris Disability Questionnaire, and Patient's Global Assessment of low back pain. ⋯ A blinded, independent adjudication committee reviewed all 6 patients with reported osteonecrosis and 4 of the 9 patients undergoing TJR. Adjudication outcomes were osteonecrosis (n=0), worsening osteoarthritis (n=5; 1 rapidly progressive), and another diagnosis or indeterminate (n=5). Tanezumab 10mg had better tolerability than tanezumab 20mg, and may represent an effective long-term treatment for chronic low back pain.

Randomized Controlled Trial Multicenter Study
Compression stockings in ankle sprain: a multicenter randomized study.
Ankle sprain is a frequently encountered traumatic injury in emergency departments and is associated with important health expenses. However, the appropriate care of this traumatic injury remains a matter of debate. We tested the hypothesis that compression stockings speed up recovery from ankle sprain. ⋯ Compression stockings failed to significantly modify the time to return to normal painless walking in ankle sprain. A beneficial effect was observed only in a subgroup of patients, as compression stockings significantly decreased the time to return to sport activity.

Multicenter Study
Computerized physician order entry and decision support improves emergency department analgesic ordering for renal colic.
Computerized physician order entry (CPOE) offers the potential for safer, faster patient care, as well as greater use of evidence-based therapy via built-in decision support. However, the effectiveness of CPOE in yielding these benefits has shown mixed results in the emergency department (ED) setting. Our objective was to evaluate the impact of CPOE implementation on analgesic prescribing and dosing practices for renal colic presentations. ⋯ The introduction of CPOE is associated with an increase in ketorolac use for ED renal colic visits. This may reflect the inclusion of ketorolac in the renal colic order set. Computerized physician order entry implementation with condition-specific electronic order sets and decision support may improve evidence-based practice.

Multicenter Study Comparative Study Observational Study
[Implementation of a specific premedication protocol for tracheal intubation in the delivery room. Practice in two level-III hospitals].
Tracheal intubation in neonates is a painful procedure performed daily in the delivery room despite the widespread development of noninvasive ventilation. Specific analgesia is not commonly performed. The objective of this observational study was to compare practices between two level-III centers: one with a specific protocol for premedication before tracheal intubation of newborns in the delivery room, the other without. ⋯ One hundred and fifteen neonates were intubated in the delivery room and included over a 4-month period: 25% of them received specific premedication before intubation, exclusively in the center with the protocol. None of the extreme premature neonates (age≤28 gestational weeks) received analgosedation before the procedure. Nalbuphine, midazolam, and sufentanil were mainly used, via the intravenous or intrarectal route. Infants receiving a premedication were significantly heavier and had a greater gestational age than the others (1500 g [range, 1180-2260 g] vs. 1170 [range, 860-1680 g] P=0.003, and 31 GW [range, 29-34 GW] vs. 29 [range, 27-32 GW] P=0.014, respectively). Most pediatricians (85-100%) favored a specific protocol for sedation before tracheal intubation. Implementation of a specific protocol allows specific analgesia to be implemented for newborns undergoing tracheal intubation. Further studies should be conducted to determine the best strategies for pain management during tracheal intubation of neonates, especially in the delivery room.

Multicenter Study Observational StudyTransversus Abdominis Plane Block in Children: A Multicenter Safety Analysis of 1994 Cases from the PRAN (Pediatric Regional Anesthesia Network) Database.
Currently, there is not enough evidence to support the safety of the transversus abdominis plane (TAP) block when used to ameliorate postoperative pain in children. Safety concerns have been repeatedly mentioned as a major barrier to performing large randomized trials in children. The main objective of the current investigation was to determine the incidence of overall and specific complications resulting from the performance of the TAP block in children. In addition, we evaluated patterns of local anesthetic dosage selection in the same population. ⋯ The upper incidence of overall complications associated with the TAP block in children was 0.3%. More important, complications were very minor and did not require any additional interventions. In contrast, the large variability of local anesthetic dosage used can not only minimize potential analgesic benefits of the TAP block but also result in local anesthetic toxicity. Safety concerns should not be a major barrier to performing randomized trials to test the efficacy of the TAP block in children as long as appropriate local anesthetic dose regimens are selected.
