This study aimed to evaluate venous hemodynamic and morphological changes and associated factors in patients with Peripherally Inserted Central Catheters (PICCs), to provide evidence for rational clinical use of PICCs. Venography was performed at different time points in 87 patients with PICCs to observe hemodynamic, morphological, and structural changes. Related laboratory blood tests were als...

The use of echocardiography in intensive care units in shock patients allows us to measure various hemodynamic variables in an accurate and a non-invasive manner. By using echocardiography not only as a diagnostic technique but also as a tool for continuous hemodynamic monitorization, the intensivist can evaluate various aspects of shock states, such as cardiac output and fluid responsiveness, ...

PURPOSE To investigate hemodynamic response to volume replacement with saline solution and hypertonic hydroxyethyl starch in hypovolemic dogs. METHODS Forty dogs under general anesthesia and hemodynamic monitoring, following measurements at baseline, were bled 20 ml x Kg(-1) and parameters were measured again after 10 minutes. The animals were randomly divided in two groups and volume replace...

OBJECTIVE The aim of this study was to (1) observe the extent to which hemodynamic and glucose measurements change in patients submitted to a dental procedure with and without a local anesthetic and a vasoconstrictor (LAVA; 2% mepivacaine with adrenaline 1100,000) and (2) correlate those parameters with the patients' anxiety levels. METHOD This was an unblinded, random, prospective, and obser...

Evaluation of hemodynamic profile by impedance plethysmography (IPG) provides functional expression of cardiovascular performance with efficacy of treatment. Objective of this study was to establish normative hemodynamic parameters by IPG. In this cross-sectional study hemodynamic parameters including cardiac output (CO), Stroke volume (SV), left ventricular ejection time (LVET), impedance (Zo)...

BACKGROUND There have been many concerns about alteration in hemodynamic parameters within and shortly after endotracheal intubation (ETI) in patients scheduled for elective coronary artery bypass grafting (CABG). OBJECTIVES We compared the attenuation effect of magnesium sulfate and lidocaine on hemodynamic responses after ETI, in patients undergoing CABG. PATIENTS AND METHODS In this rand...

conclusions intravenous magnesium reduces postoperative ileus, postoperative severe pain and intra/post operative analgesic requirements in patients after major gi surgery. no side effects of magnesium in these doses were seen, so it seems to be beneficial along with routine general anesthesia in major gi surgeries. patients and methods a randomized, double blind, placebo controlled study was p...

conclusions this study suggests that obese patients in hs may have a higher risk of hemodynamic instability compared to their nonobese counterparts primarily due to obesity-induced increases in intra-abdominal pressure resulting in reduced venous return. results in hemorrhage simulation, moderate increases in bmi were found to produce greater decreases in map and co compared to the normal subje...

The effects of electroacupuncture (EA) on intraocular pressure (IOP) and hemodynamic parameters were evaluated in isoflurane anesthetized 10 (5 males, 5 females) normal mongrel dogs (8.1-9.8 kg, 6-8 years old). After determination of baseline IOP and hemodynamic parameters (cardiac index, systolic arterial pressure, diastolic arterial pressure, heart rate and systemic vascular resistance index)...
