Effect of Regional Anesthesia Techniques on Hemodynamic Variables Measured With FloTrac/Vigileo™ System: A Prospective Cohort Study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background and objectives Neuraxial anesthesia, particularly the subarachnoid block (SAB) or spinal anesthesia, is a viable option utilized for the surgical management of proximal femoral fractures (PFF) in the geriatric population. The hemodynamic effects of SAB could be detrimental in the geriatric population, especially with cardiac comorbidities. A segmental epidural or lumbosacral plexus block (LSPB) is particularly safe for this cohort while undergoing proximal femoral nail (PFN) surgery. We decided to monitor variations in cardiac output (CO) and stroke volume (SV) in a cohort of patients who were undergoing proximal femoral nailing for PFFs. The FloTrac/Vigileo™ System was employed to monitor hemodynamic variables continuously. Methods This prospective, observational study included 29 patients with PFFs. Heart rate, CO, SV, and mean arterial pressure (MAP) were continuously monitored from the commencement of regional anesthesia (segmental epidural or LSPB) to the conclusion of the surgical procedure. Before regional anesthesia techniques, each patient was administered a mini-fluid challenge. Results Eleven patients were recruited in the epidural group, and 18 patients in the LSPB group. Compared to the epidural group, for each unit increase in SV in the LSPB group, the rate of increase in MAP was higher by 0.13 (p<0.001). Compared to the epidural group, for each unit increase in CO in the LSPB group, the rate of increase in MAP was higher by 2.78 (p<0.001). Compared to the epidural group, for each minute passed under the LSPB group, the rate of increase in CO was lower by 2.18 (p<0.001). Compared to the epidural group, for each minute passed under the LSPB group, the rate of increase in SV was lower by 0.05 (p<0.001). In four patients in whom LSPB was administered, noradrenaline and vasopressors were given, while six patients in the epidural group received inotropes and vasopressors. Conclusions In patients having PFN for PFFs, regional anesthesia in the form of a segmental epidural or lumbosacral plexus provides steady hemodynamics during the perioperative phase. Furthermore, maintaining proper fluid balance can meet a fluid challenge even in high-risk populations.
