The rate adaptive sensors applied to cardiac pacing should respond as promptly as the normal sinus node with an highly specific and sensitive detection of the need of increasing heart rate. Sensors operating alone may not provide optimal heart responsiveness: central venous pH sensing, variations in the oxygen content of mixed venous blood, QT interval, breathing rate and pulmonary minute venti...
Objective: Few studies are available on the hemodynamic changes acutely determined by Primary Percutaneous Coronary Intervention (PCI) in ST-Elevation Myocardial Infarction (STEMI) patients, probably for the difficult evaluation of hemodynamic variables in this acute setting. Therefore, the paper is to evaluate the variations of several hemodynamic parameters determined by PCI using PRAM (Press...
BACKGROUND The clinical and hemodynamic assessment at the bedside and the use of pulmonary artery catheter for the estimation of hemodynamic data have been used in decompensated heart failure. However, there are no data on the use of continuous noninvasive hemodynamic monitoring. OBJECTIVE To compare the data obtained through noninvasive hemodynamic monitoring with invasive ones in patients w...
Background: Patients who require surgery on the lower extremities are considered to be a high risk group from the point of anesthesia. This study was performed to compare sitting and lateral positions in spinal anesthesia method with hyperbaric bupivacaine 0.5% for hemodynamic status and analgesic period in patients under vascular surgery of the lower limbs in Imam-Khomeini Hospital Complex aff...
Objective(s): This research aimed to test the impact of liver ischemia/reperfusion (IR) insult on the activity of antioxidant enzymes, functional enzymes, histological, and hemodynamic parameters of heart, as well as protective function of crocin on these variables in rats. Materials and Methods: Thirty two rats were randomly assigned into 4 experimental groups (8 rats in each). I: sham-oper...
Aims and background: A major surgery such as a laparotomy can induce severe pain in a patient. However administration of pain control medications can have dramatic effects on the hemodynamic status of the patient. Therefore, the aim of this study was to investigate intravenous infusion of magnesium sulfate for pain control and its’ effect on the hemodynamic status of the patient after laparot...
Aims and Background: Although controversial, many studies have shown effectiveness of colloid loading as a substitute for crystalloids on reducing the incidence of hypotension in spinal anesthesia. This study was conducted to compare the effects of three intravenous fluid regimens on hemodynamic changes following spinal anesthesia in cesarean section. The regimens included 6% Hydroxy ethyl star...
Aims and Background: Hemodynamic changes during laparoscopy and postoperative pain after laparoscopic surgery are important issues. Therefore, in this study we examined the effect of oral clonidine on hemodynamics and postoperative pain control after laparoscopic cholecystectomy. Materials and Methods: The study was a randomized clinical trial. 61 patients, candidate for laparoscopic cholecyst...
Background and purpose: Âdminstration Fluid balance in critically ill patients is a common problem in ÏÇÜ and is often associated with a poor outcome. Ïn addition, important clinical changes in hemodynamic variables occur after diuretic therapy. This study was conducted to evaluate the safety and relative effectiveness of two diurectic protocols in ÏÇÜ. Materials and methods : Twenty- two ...
Abstract Background Ketamine is an anesthetic drug that is importantly analgesic without respiratory depression. Ketamine increases blood pressure and heart rate. Propofol is an anesthetic drug with good sedation, rapid recovery, but it causes respiratory depression, low heart rate and low blood pressure. Combination of Ketamine and Propofol provides sedation, analgesia and rapid recovery wit...
