To investigate the association between cardiovascular mortality and short-term variabilities in blood pressure and heart rate, we performed a long-term prospective study of ambulatory blood pressure monitoring in Ohasama, Japan, starting in 1987. We obtained ambulatory blood pressure and heart rate in 1542 subjects >/=40 years of age. Blood pressure and heart rate variabilities were estimated a...

conclusions: the effects of propofol on hemodynamics and arterial oxygen pressure during one- or two-lung ventilation were not different from those of isoflurane. results: sixty patients (mean age = 4124.18 ± 18.63 years) were divided into two groups. the age and gender of the subjects were not statistically different between the two groups. in the propofol group, the arterial oxygen pressure d...

To delineate the relative roles of genetic and environmental factors on physiological variations of blood pressure and heart rate, we performed 24-hour ambulatory blood pressure monitorings with simultaneous polygraphic sleep recordings in 28 monozygotic and 16 dizygotic healthy young male twin pairs investigated in a standardized physical and social environment. Blood pressure and heart rate w...

Background: Esophagectomy is considered to be the main treatment for esophageal malignancies. Among the different methods, transhiatal approach can cause less damage to patients and is widely used however, manipulation of esophagus result in heart rate and blood pressure variations. The aim of this study was to investigate changes in blood pressure and heart rhythm during transhiatal esophagect...

Tonsils are located in the upper airway.serious complications may threaen the patients during and following surgical operations in this area.this study was done to assess the effectiveness of local lidocaine infiltration for redusing complications of tonsillectomy.in this study,74 patients were randomly selected.37 patients received local lidocaine infiltration(2ml of 2% lidocaine)in the tonsil...

background: controlling the hemodynamic situation of patients who have spinal operation is of prime importance, and maintaining the heart rate and blood pressure in normal or low- normal levels in these patients can reduce their bleeding loss. one of the commonly used drugs for this purpose is remifentanil. another sedative-hypnotic-analgesic drug, with acceptable effects is dexmedetomidine. th...

Music as a therapeutic non-invasive tool-could be used as an effective intervention in nursing practice. The aim of this study was to survey effect of music upon patients’ physiological parameters following open heart surgery. A quasi-experimental study was performed on 60 patients under open heart surgery referred to intensive care unit. Patients were randomly divided into two groups including...
