Multiple longitudinal studies have demonstrated reasonable stability of blood pressure (BP) levels and hemodynamics throughout childhood and adolescence and into adulthood. Part of this stability might be caused by genetic factors that are expressed steadily over time. We aimed to determine the relative contributions of genetic and environmental factors to the stability of BP and underlying hem...

Preemptive analgesia aims to prevent the sensitization of central nervous system, hence the development of pathologic pain after tissular injury. The aim of the study was to assess the effect of preincisional clonidine treatment on analgesic consumption and hemodynamic stability compared to clonidine administered at the end of the operation and control group. Ninety-one patients undergoing elec...

BACKGROUND AND PURPOSE Rupture risk of intracranial aneurysms may depend on hemodynamic characteristics. This has been assessed by comparing hemodynamic data of ruptured and unruptured aneurysms. However, aneurysm geometry may change before, during, or just after rupture; this difference causes potential changes in hemodynamics. We assessed changes in hemodynamics in a series of intracranial an...

Acute renal failure (ARF) occurs in 10 per cent to 23 per cent of intensive care unit patients with mortality ranging from 50 per cent to 90 per cent. ARF is characterized by an acute decline in renal function as measured by urine output (UOP), serum creatinine, and blood urea nitrogen (BUN). Causes may be prerenal, intrarenal, or postrenal. Treatment consists of renal replacement therapy (RRT)...

background : children suffering from cancer always require pain relief and reduce anxiety when undergoing painful procedures. the aim of this study is to compare the effect of pethedine and ketamine administration in cancer-diagnosed children undergoing bone marrow aspiration and biopsy procedures. subjects and methods : a randomized, double-blinded, crossover trial was carried out on 57 childr...

Hemodynamic instability and inadequate cardiac performance are common in critically ill children. The clinical assessment of hemodynamic status is reliant upon physical examination supported by the clinical signs such as heart rate, blood pressure, capillary refill time, and measurement of the urine output and serum lactate. Unfortunately, all of these parameters are surrogate markers of cardio...

INTRODUCTION Acute hemodynamic instability increases morbidity and mortality. We investigated whether early non-invasive cardiac output monitoring enhances hemodynamic stabilization and improves outcome. METHODS A multicenter, randomized controlled trial was conducted in three European university hospital intensive care units in 2006 and 2007. A total of 388 hemodynamically unstable patients ...

Background: Lumbar puncture (LP) and bone marrow aspiration or biopsy in pediatric patients with hematological diseases is often repeated at regular intervals. These procedures are painful and unpleasant and bring a lot of stress for the children and their families. This study aimed to compare the effectiveness of two drug combinations of propofol-ketamine and propofol-remifentanil in children ...

introduction: cardiac dysfunctions have been well known in patients with major thalassemia. some studies have focused on differences in blood pressure and heart rate between these patients and normal population, while this view has not been proven in other studies. given the importance of hemodynamic factors in the health of these individuals, we intend to test the hypothesis as to whether or n...
