Impact of nitroglycerin-induced vasodilation on stroke volume and diuretic response in acute heart failure: A protocol for a mechanistic trial.
Acute heart failure is a clinical syndrome characterized by cardiac dysfunction and neurohumoral activation, encompassing complex underlying pathophysiology which may vary across phenotypes. Nitroglycerine is a nitrate donor with vasodilatory effects on both venous capacitance vessels and arterial resistance vessels in higher doses, typically used with the aim of reducing congestion, preload, and afterload. A limited number of studies have proposed that nitroglycerin could promote diuresis and natriuresis. However, the exact hemodynamic effects of nitroglycerin remain uncertain in the clinical setting of acute decompensated heart failure. We hypothesize that intravenous nitroglycerin induces a significant increase in stroke volume and urinary output while lowering cardiac filling pressures. ⋯ This study will assess the acute effects of vasodilation on stroke volume and urinary output in hospitalized patients with AHF. Furthermore, characterizing the hemodynamic profile of the patient prior to vasodilation may help explore which patients will benefit from vasodilation.

Assessing pain in neonates is crucial for their management but is inherently subjective. This study investigated the effects of visual attention, gaze patterns, and empathic responses of neonatal healthcare professionals on their assessments of neonatal pain. ⋯ The study emphasises the importance of visual cues and empathy in neonatal pain assessment, highlighting the roles of healthcare professionals and stimulus presentation formats. It addresses challenges in understanding neonatal pain, advocating for standardised protocols. Using eye-tracking technology, the research explores how professionals' visual attention and empathy affect pain evaluations, suggesting more objective assessment methods.

Exploring management reasoning when discharging high-risk postoperative patients from the post-anaesthesia care unit.
Decision-support tools for detecting physiological deterioration are widely used in clinical medicine but have been criticised for fostering a task-oriented culture and reducing the emphasis on clinical reasoning. Little is understood about what influences clinical decisions aided by decision-support tools, including professional standards, policies, and contextual factors. Therefore, we explored management reasoning employed by anaesthesiologists and PACU nurses in the post-anaesthesia care unit during the discharge of high-risk postoperative patients. ⋯ While decision-support tools offer cognitive aid and help standardise patient trajectories, they also limit professional discretion in management reasoning and can potentially compromise care and treatment. This highlights the need for a balanced approach that considers both the benefits and limitations of these tools in clinical decision-making.

Ruptured aneurysms visualized by vessel wall MRI (VW-MRI) exhibit characteristic aneurysm wall enhancement (AWE). A secondary bulge of the aneurysmal wall, called a bleb, is often the site of rupture in ruptured aneurysms. We hypothesized that a higher degree of AWE would identify the rupture point in aneurysms with multiple blebs. ⋯ AWE is associated with the bleb rupture status independent of WSS. Contrast-enhanced VW-MRI may be a useful noninvasive tool for identifying the rupture point and guiding the treatment strategy.
