Review Meta Analysis
The Effect of Perioperative Music on the Stress Response to Surgery: A Meta-analysis.
Current perioperative patient care aims to maintain homeostasis by attenuation of the stress response to surgery, as a more vigorous stress response can have detrimental effects on postoperative recovery. This systematic review and meta-analysis aims to assess the effect of perioperative music on the physiological stress response to surgery. ⋯ Perioperative music can attenuate the neuroendocrine stress response to surgery.

Alcohol (EtOH) poses a challenge in traumatic brain injuries (TBIs) given its metabolic and neurologic impact. Studies have had opposing results regarding mortality and complication rates in the intoxicated TBI patient. We hypothesized that trauma mechanism, brain injury severity, and blood alcohol concentration (BAC) would influence the impact of EtOH on mortality in TBI. ⋯ We found that EtOH is not associated with mortality in the patient with TBI, suggesting no causative effect. However, EtOH showed some predictability of mortality based on a receiver operator characteristic analysis. Interestingly, EtOH was associated with lower infectious complications, suggesting an immunomodulatory effect of EtOH in TBI.

Comparative Study
Intrathecal Morphine Versus Nerve Blocks in an Enhanced Recovery Pathway for Pancreatic Surgery.
Intrathecal morphine (ITM) and peripheral nerve blocks are accepted techniques for analgesia after abdominal surgery, but their efficacy has not been evaluated in the context of an enhanced recovery pathway (ERP) in pancreatic surgery. ⋯ ITM was associated with reduced pain scores and opioid requirements compared with peripheral nerve blocks in an ERP for pancreatic surgery.

Soluble suppression of tumorigenicity 2 (sST2), a decoy receptor for interleukin (IL)-33, has emerged as a novel biomarker in various disease processes. Recent studies have elucidated the role of the sST2/IL-33 complex in modulating the balance of Th1/Th2 immune responses after tissue stress. However, the role of sST2 as a biomarker after traumatic injury remains unclear. To address this, we evaluated serum sST2 correlations with mortality and in-hospital adverse outcomes as endpoints in blunt trauma patients. ⋯ Elevations in serum sST2 levels are associated with poor clinical trajectories and mortality after blunt trauma. High sST2 coupled with low IL-33 associates with severe injury, mortality, and worse clinical outcomes. These findings suggest that sST2 could serve as an early prognostic biomarker in trauma patients and that sustained elevations of sST2 could contribute to a detrimental suppression of IL-33 bioavailability in patients with high injury severity.

Rib fractures are a common consequence of traumatic injury and can result in significant debilitation. Rib fixation offers fracture stabilization, resulting in improved outcomes and decreased pulmonary complications, especially in high-risk groups such as those with flail segments. However, commercial rib fixation has only recently become clinically prevalent, and we hypothesize that significant variability exists in its utilization based on injury pattern and trauma center. ⋯ Rib fixation is infrequently used at trauma centers in Pennsylvania. It is used more frequently in nonflail injuries, and its use may be associated with the occurrence of pulmonary complications. Significant center-level variation exists in rib fixation rates among multiple fractured patients. A significant number of patients are cared for at centers that do not perform rib fixation. Further research is needed to illicit better-defined indications for operative fixation, and opportunities exist to further the penetrance of this practice to all trauma centers.
