Randomized Controlled Trial
Effects of Serratus Anterior Plane Block on Early Recovery from Thoracoscopic Lung Resection: A Randomized, Blinded, Placebo-Controlled Trial.
The efficacy of serratus anterior plane block for treatment of pain after minimally invasive thoracic surgery remains unclear. This trial assesses the impact of serratus anterior plane block on postoperative opioid consumption and on measures of early recovery after thoracoscopic lung resection. ⋯ The protocol-specified intention-to-treat analysis demonstrated that serratus anterior plane block did not result in a significant reduction in opioid consumption when added to a multimodal analgesic regimen after thoracoscopic anatomic lung resection. The sensitivity as-treated analysis showed a significant and modest clinical reduction in the primary outcome that warrants further investigation.

Comparative Study
Mechanical power in decelerating flow versus square flow ventilation in pediatric ARDS.
Mechanical power is a summary variable quantifying the risk of ventilator-induced lung injury. The original mechanical power equation was developed using square flow ventilation. However, most children are ventilated using decelerating flow. It is unclear whether mechanical power differs according to mode of flow delivery. This study compared mechanical power in children with acute respiratory distress syndrome who received both square and decelerating flow ventilation. ⋯ Mechanical power was marginally lower in square flow than in decelerating flow, although the clinical significance of this is unclear. Upward of 30% of mechanical power may go toward overcoming resistance, regardless of age. This is nearly three-fold greater resistance compared to what has been reported in adults.

Bleeding during cardiac surgery may be refractory to standard interventions. Off-label use of factor eight inhibitor bypass activity (FEIBA) has been described to treat such bleeding. However, reports of safety, particularly thromboembolic outcomes, show mixed results, and reported cohorts have been small. ⋯ Low-dose FEIBA administration during cardiac surgery does not increase risk of thromboembolic events, intensive care unit length of stay, or mortality in a propensity-matched cohort. Higher doses were associated with increased acute renal failure and postoperative transfusion. Further studies are required to establish the efficacy of activated factor concentrates to treat refractory bleeding during cardiac surgery.

Acute liver injury is a disease characterized by severe liver dysfunction, caused by significant infiltration of immune cells and extensive cell death with a high mortality. Previous studies demonstrated that the α7 nicotinic acetylcholine receptor (α7nAChR) played a crucial role in various liver diseases. The hypothesis of this study was that activating α7nAChR could alleviate acute liver injury and investigate its possible mechanisms. ⋯ The authors' study revealed that activating α7nAChR could protect against LPS/D-Gal-induced acute liver injury by inhibiting hepatic inflammation and necroptosis possibly via regulating immune cells infiltration and inhibiting STING signaling pathway.
