Computer-controlled closed-loop norepinephrine infusion system for automated control of mean arterial pressure in dogs under isoflurane-induced hypotension: a feasibility study

Frontiers in Veterinary Science
IntroductionIntra-operative hypotension is a common complication of surgery under general anesthesia in dogs and humans. Computer-controlled closed-loop infusion systems of norepinephrine (NE) have been developed and clinically applied for automated ...

Enhanced norepinephrine sensitivity in renal arteries at elevated transmural pressure

, 1990
The electrical and mechanical responses of vascular smooth muscle to norepinephrine were compared at three different levels of transmural pressure (60, 100, and 140 mmHg) in cannulated small arteries that were isolated from dog kidneys.

Transcutaneous auricular vagus nerve stimulation in drug‐resistant epilepsy: A randomized, sham‐controlled crossover trial with exploratory EEG and MRI response phenotyping

Epilepsia Open, EarlyView.
Abstract Objective Transcutaneous auricular vagus nerve stimulation (taVNS) is a noninvasive neuromodulation strategy for drug‐resistant epilepsy, but clinical response is heterogeneous. We examined whether electroencephalographic (EEG) and structural magnetic resonance imaging (MRI) phenotypes were associated with active‐specific clinical benefit from

Trendelenburg positioning with or without norepinephrine infusion for haemodynamic support in anaesthetised hypovolemic horses

Equine Veterinary Journal, EarlyView.
Abstract Background Intraoperative haemorrhage during equine anaesthesia is a rare but potentially fatal complication requiring prompt haemodynamic support. Postural manoeuvres such as Trendelenburg (TL) positioning and vasopressor support augment venous return and improve cardiac output (CO), yet their efficacy in anaesthetised hypovolemic horses ...

Chronic norepinephrine infusion and adrenergic function of hypertrophied hearts

, 1985
The ability of chronic subpressor norepinephrine infusion to prevent depletion of myocardial norepinephrine stores and deterioration of myocardial adrenergic nerve function in congestive heart failure was examined.

Dexmedetomidine infusions improve cardiovascular and renal function in anaesthetised, experimentally endotoxaemic horses

Equine Veterinary Journal, EarlyView.
Abstract Background Dexmedetomidine infusions are beneficial in anaesthetised endotoxaemic horses when administered concurrent to endotoxin, but post‐conditioning effects are unknown. Objectives To evaluate whether a dexmedetomidine infusion is beneficial in horses administered Escherichia coli O55:B5 lipopolysaccharides (LPS) endotoxin prior to ...

Measurement of total and organ-specific norepinephrine kinetics in humans

, 1984
A variety of biochemical tests, most notably measurement of the plasma concentration of norepinephrine, have been used to quantify overall sympathetic nervous system activity in humans.

Implantable electrochemical sensors for continuous blood monitoring

FlexMat, EarlyView.
Implantable electrochemical sensors enable direct, in situ, and continuous blood monitoring, shifting diagnosis from population‐based averages to dynamic, individualized analysis. This review systematically examines the influence of the unique blood properties on sensor design.

Effect of norepinephrine on consumption of oxygen in perfused skeletal muscle from cold-exposed rats

, 1988
The effect of norepinephrine on the consumption of O2 was studied in the skeletal muscle in the perfused hindlimbs of rats that had been kept at 4 degrees C for 5-25 days.

Postoperative Hemoglobin and Transfusion Rates Do Not Influence Revision of Head and Neck Free Flap in a Cohort of 259 Patients

Head &Neck, EarlyView.
ABSTRACT Introduction Recent literature advocates restrictive transfusion thresholds (Hb < 7 g/dL). The aim of this study was to evaluate if postoperative hemoglobin levels and transfusions influence Free Flap Revision (FFR). Methods This single center retrospective study included all patients who underwent head and neck surgery with free flap ...
