Tidal volume challenge to predict fluid responsiveness in the operating room: An observational study

CONCLUSION The changes in PPV and SVV obtained after VTC are reliable and comparable to the changes in CI and SVI obtained after EEOT performed at 8 ml kg−1 PBW in predicting fluid responsiveness in neurosurgical patients. TRIAL REGISTRATION ACTRN12618000351213.

Authors: Lv X, Tang R, Gao Z, Hu D, Li G, Lang Y, He J Abstract Functional degradation of the motor cortex usually results from brain injury, stroke, limb amputation, aging or other diseases. Currently, there are no ideal means of treatment, other than medication and sports rehabilitation. The present study investigated whether electrical stimulation of the sciatic nerve can activate the motor-related area of the brain. The study is based on a self-developed fully implantable nerve electrical stimulator and a self-developed multi-channel electroencephalogram (EEG) electrode array. The sciatic nerves of Sprague-Dawl...

This article reviews various potential variables for the prediction of fluid responsiveness in the pediatric population. Differences in anatomic and physiologic characteristics between the pediatric and adult populations are covered. In addition, some important considerations are discussed for future studies on fluid responsiveness in the pediatric population. PMID: 31591858 [PubMed - in process]

Background: Our previous study showed that propofol, one of the widely used anesthetic agents, can attenuate subarachnoid hemorrhage (SAH)-induced early brain injury (EBI) via inhibiting inflammatory and oxidative reaction. However, it is perplexing whether propofol attenuates inflammatory and oxidative reaction through modulating PI3K/Akt pathway. The present study investigated whether PI3K/Akt pathway is involved in propofol's anti-inflammation, antioxidation, and neuroprotection against SAH-induced EBI.

HISTORICALLY, carotid endarterectomy (CEA) surgery has generated several disputes regarding the choice of anesthesia provided and intraoperative neuromonitoring. The landmark General Anesthesia versus Local Anesthesia trial,1 which included 3,526 patients, showed no difference in the occurrence of stroke, myocardial infarction, or death at 30 days after surgery with respect to either local or general anesthesia. Harky et al.2 conducted a systematic review and meta-analysis of general versus local anesthesia in CEA surgery and concluded that each of the anesthetic techniques was noninferior to one another.

AbstractPurposeHemodynamic management during low central venous pressure (L-CVP)-assisted hepatectomy involves fluid restriction during resection and fluid resuscitation after resection. Recently, high stroke volume variation (SVV) has been reported as an alternative to L-CVP for reducing blood loss during a hepatectomy. The current study evaluated the impact of a newly implemented SVV-based goal-directed therapy (GDT) protocol on blood loss during hepatectomy.MethodsWe conducted a before –after comparative study, which included L-CVP-assisted hepatectomy cases (control group) and GDT-assisted hepatectomy cases (inte...

Comparison of TransFemoral Transcatheter Aortic Valve Replacement Performed With a Minimally Invasive Simplified Technique: "FAST" Versus a Standard Approach. J Invasive Cardiol. 2019 Oct;31(10):300-306 Authors: Lefèvre G, Jégou A, Dambrin G, Picard F, Anconina J, Pouzet B, Guesnier L, Cheikh Khelifa R, Hilpert L, Doan HL, Favereau X Abstract OBJECTIVES: To assess the safety and efficacy of a new simplified procedure for transfemoral (TF) transcatheter aortic valve replacement (TAVR): the FAST protocol. BACKGROUND: A minimalist approach for TF-TAVR has been reported. The goa...

This study sought to determine the feasibility and safety of outpatient, unsedated PEG implementation in stroke patients. This retrospective cohort study involved stroke victims who underwent unsedated outpatient PEG insertion from 2014 to 2017 at our Surgical Endoscopy Unit. Patients were given pharyngeal anesthesia with lidocaine 10% spray, while the PEG tube was placed under local anesthesia. The incidence of intraprocedural and postprocedural complications and 30-day mortality rate were recorded. Data from 127 cases were analyzed. The procedures were performed with minor, transient complications, which resolved after r...

Abstract Atrial fibrillation (AF) is the most common arrhythmia in the perioperative period. Previously considered a benign and self-limited entity, recent data suggest that perioperative AF is associated with considerable morbidity and mortality and may predict long-term AF and stroke risk in some patients. Despite known risk factors, AF remains largely unpredictable, especially after noncardiac surgery. As a consequence, strategies to minimize perioperative risk are mostly supportive and include avoiding potential arrhythmogenic triggers and proactively treating patient- and surgery-related factors that might pr...
