conclusions closed suction caused fewer disturbances in patients’ hemodynamic condition, took shorter time, and is more economical. therefore, this method can replace open suction method in caring of severely critically ill patients. results no significant differences were observed between the two suctioning methods in terms of mean systolic blood pressure (p = 0.075), diastolic blood pressure ...

1. To investigate the influence of heart rate variability on blood pressure variability, short-term variability in heart rate and blood pressure was studied in 10 children with fixed ventricular pacemaker rhythm (80 beats/min). Ten healthy children, in sinus rhythm, served as a reference population. 2. Arterial blood pressure and heart rate were measured continuously using a finger arterial dev...

Background: Induction of anesthesia in patients that undergo cardiac surgery has more risk than others, because of specific cardiovascular effects of the anesthetic drugs and the preoperative state of these patients, so the hemodynamic stability is very important in these patients. It seems that midazolam have less cardiovascular side effects than thiopentone. In this study, the effects of mid...

bachground: to induce anesthesia in cesarean, thiopental is often used, and propofol may be used as an alternative. considering different effects and contradictions deriving from previous studies, this study aimed to investigate the effects of thiopental and propofol on apgar score. methods: a double blind clinical trial study was designed on pregnant women scheduled for elective cesarean. pati...

To characterize the normal nycterohemeral blood pressure and heart rate profiles and to delineate the relative roles of sleep and circadian rhythmicity, we performed 24-hour ambulatory blood pressure monitoring with simultaneous polygraphic sleep recording in 31 healthy young men investigated in a standardized physical and social environment. Electroencephalographic sleep recordings were perfor...
