Randomized Controlled Trial
Adjunctive virtual reality pain relief after traumatic injury: a proof-of-concept within-person randomized trial.
In this study, we hypothesized that immersive virtual reality (VR) environments may reduce pain in patients with acute traumatic injuries, including traumatic brain injuries. We performed a randomized within-subject study in patients hospitalized with acute traumatic injuries, including traumatic brain injury with moderate pain (numeric pain score ≥3 of 10). We compared 3 conditions: (1) an immersive VR environment (VR Blu), (2) a content control with the identical environment delivered through nonimmersive tablet computer (Tablet Blu), and (3) a second control composed of donning VR headgear without content to control for placebo effects and sensory deprivation (VR Blank). ⋯ VR Blu was perceived as most effective by patients for pain reduction (F 2,66.84 = 16.28, P < 0.001), and changes in measures of parasympathetic activity including heart rate variability (F 2,55.511 = 7.87, P < 0.001) and pupillary maximum constriction velocity (F 2,61.41 = 3.50, 1-tailed P = 0.038) echoed these effects. There were no effects on opioid usage. These findings outlined a potential clinical benefit for mollifying pain related to traumatic injuries.

Determining Intraosseous Needle Placement Using Point-of-Care Ultrasound in a Swine (Sus scrofa) Model.
Intraosseous (IO) access is critical in resuscitation, providing rapid access when peripheral vascular attempts fail. Unfortunately, misplacement commonly occurs, leading to possible fluid extravasation and tissue necrosis. Current research exploring the utility of bedside ultrasound in confirming IO line placement is limited by small sample sizes of skeletally immature subjects or geriatric cadaveric models. The objective of this study was to investigate the potential value of ultrasound confirming IO needle placement in a live tissue model with bone densities approximated to the young adult medical or trauma patient. ⋯ Within the context of this study, point-of-care ultrasound with CPD did not reliably confirm IO line placement. However, more accurate assessments of functional and malpositioned catheters were noted in sonographers with greater than 4 years of experience. Future study into experienced sonographers' use of CPD to confirm IO catheter placement is needed.

Randomized Controlled TrialSOFTLY: Comparison of outcomes of rigid versus soft collar during emergency department investigation for potential cervical spine injury in low-risk blunt trauma patients - A pilot study.
Blunt trauma patients with potential cervical spine injury are traditionally immobilised in rigid collars. Recently, this has been challenged. The present study's objective was comparison of the rate of patient-oriented adverse events in stable, alert, low-risk patients with potential cervical spine injuries immobilised in rigid versus soft collars. ⋯ Use of soft rather than rigid collar immobilisation for low-risk blunt trauma patients with potential cervical spine injury is significantly less painful for patients and results in less agitation. A larger study is needed to determine the safety of this approach or whether collars are required at all.

Effect of TENS on Vacuum Pain in Acute Soft Tissue Trauma.
In the literature, the effect of TENS on acute pain has been investigated, and no study has been found on its effect on pain associated with VAC application. This randomized controlled trial was designed to assess the efficacy of TENS application in pain caused by vacuum applied in acute soft tissue trauma of the lower extremity. ⋯ The results obtained from our study showed that TENS reduced the pain caused by vacuum applied in acute soft tissue trauma of the lower extremity. It is thought that TENS may not replace traditional analgesics but may help reduce the level of pain and contribute to healing by increasing comfort during painful procedures.

Prehospital Tranexamic Acid for Severe Trauma.
Whether prehospital administration of tranexamic acid increases the likelihood of survival with a favorable functional outcome among patients with major trauma and suspected trauma-induced coagulopathy who are being treated in advanced trauma systems is uncertain. ⋯ Among adults with major trauma and suspected trauma-induced coagulopathy who were being treated in advanced trauma systems, prehospital administration of tranexamic acid followed by an infusion over 8 hours did not result in a greater number of patients surviving with a favorable functional outcome at 6 months than placebo.
