abstract background: providing better surgical conditions with meticulous control of intraocular pressure (iop) is one of the most important factors that affect the success rate in ophthalmic surgery. clonidine is a selective central α2 agonist with analgesic, antianxiety and sedative effects which makes it a good choice in premedication recently. in this study, we compared the effects of oral ...

Background In off-pump coronary artery bypass (OPCAB) surgery, the most critical complication is hemodynamic deterioration, which can occur during displacement of the heart to expose the target vessels. Pre-operative intra-aortic balloon pump (IABP) therapy has shown to improve cardiac performance and facilitates access to the target coronary artery while maintaining hemodynamic stability, espe...

We consider that general anesthesia will be an appropriate and safe method as regional methods could lead to significant time loss in the prevention or minimization of complications. High blockage required for regional anesthetic methods in pregnant women with TGA and the maintenance of hemodynamic stability may become difficult due to neuroaxial sympathectomy even if a successful neuroaxial bl...

Thorasic paravertebral block (PVB) thorasic epidural and pectoral nerve blocks can be used as a regional anesthetic option for breast surgery. Thorasic PVB is defined as injection of local anesthesthetic solution at the site where spinal nerves emerges from paravertebral foramen. It produces unilateral motor, sensory and sympathetic block, hence PVB could be an anesthetic choice in patients wit...

BACKGROUND Peri-operative statin therapy in cardiac surgery cases is reported to reduce the rate of mortality, stroke, postoperative atrial fibrillation, and systemic inflammation. Systemic inflammation could affect the hemodynamic parameters and stability. We set out to study the effect of statin therapy on perioperative hemodynamic parameters and its clinical outcome. METHODS In a single ce...

Although oral clonidine premedication is known to reduce the hemodynamic response under general anesthesia, effects of the hemodynamic response during sedated fiberoptic nasal intubation have not yet been examined. Our aim was to compare the effects of clonidine premedication on hemodynamic responses with those of atropine and hydroxyzine premedication during sedated fiberoptic nasal intubation...

Use of etomidate for anesthesia induction is still debated. In the previous issue of Critical Care, Heinrich and colleagues reported that etomidate for anesthesia induction had similar outcome in comparison with other drugs, in a specific population of 3,054 patients ahead of major cardiac surgery. For the authors, the similar outcomes for mortality and length of hospital stay add to the hemody...

Acute renal failure (ARF) requiring dialysis is a common complication of patients in intensive care unit (ICU). Dialysis can be performed with either intermittent hemodialysis (IHD) or continuous renal replacement therapy (CRRT). CRRT is associated with less hemodynamic instability. Therefore, it is preferred in critically ill and hypotensive patients in ICU. However, current evidence does not ...

Even in patients with chronic renal failure and chronic intermittent hemodialysis, continuous venovenous hemofiltration (CVVH) is the most often practiced renal replacement technique in the intensive care unit. Although patients show less hemodynamic instability during CVVH than during hemodialysis, it requires a blood flow exceeding 200 ml/min in the extracorporeal circuit necessitating the us...

About 10% of patients in the intensive care unit which develop acute renal failure will depend on renal replacement therapy. Although there are no data showing reduction in mortality when compared with intermittent therapy, continuous therapies provide higher cumulative doses of dialysis and greater hemodynamic stability. However, have high costs and are not available in many centers. In this c...
