[Effects of intratracheal suctioning on hemodynamic parameters and arterial oxygen]

intubated patients with the aim of cleaning airway for good oxygenation. The aim of this study was to evaluate the effects of intratracheal suctioning on blood pressure, heart rate, and arterial oxygen saturation. Intratracheal suctioning is a standard method of nursing care for admitted to intensive care unit of Kashani teaching center of Shahr-e-kord University in 2005. The data were collected by a questionnaire form 35 patient by observation and measurement of blood pressure, heart rate and arterial oxygen saturation. This was a semi-experimental research in which the patients and heart rate increased and arterial oxygen saturation decreased significantly, when compared with pre-suctioning period. The same occurred when these parameters were compared between pre-suctioning period and 1 minute post-suction, except for arterial oxygen saturation that had not statistically significant decline, 1 minute after suctioning. The parameters under study remained increased [including arterial oxygen saturation that decreased during suctioning] 3 minutes after suctioning, but this increase was not statistically significant when compared with pre-suctioning period. The study showed that parameters in 1 and 3 minutes after suctioning were also significantly different from those of suctioning period. The findings showed that during suctioning, systolic pressure, diastolic pressure, pressure and heart rate [increase] and arterial oxygen saturation [decrease] occurs during suctioning and maximum changes of blood pressure and heart rate [decrease] and arterial oxygen saturation [increase] occurs 3 minutes after suctioning. Therefore, hyper oxygenation, hemodynamic and SpO2 monitoring before, during and after suctioning are recommended. The finding of this research showed that the maximum changes of blood

[Sleep disorders in patients with congestive heart failure hospitalized in Hajar hospital, Shahrekord, 2003]

Sleep is an important regular and repeated biologic period and leads to refreshment of human life both physically and mentally. One third of human life is spending in sleep and lack of it, endangers human well being. This phenomenon usually is affected by both internal and external factors such as age, sex, drug, disease and surgery. Therefore, the aim of this study was to assess the sleep disorders in congestive heart failure patients in Hajar hospital of Shahrekord in 2003. This descriptive-analytical study was performed on 205 patients with an ejection fraction less than 40%. The sampling was conducted using simple method from September to November, 2003. Data were collected using a questionnaire comprising two parts of questions and expresses, which was filled in by the researchers. Data were analyzed by Chi-square test using SPSS. Prevalence of sleep disorders in congestive heart failure patients was%51. The most prevalent disorder for start sleep stage was disturbing thoughts [62%] and for co-sleep, stage was sleep rising by slight noise [77.1%] and for sleep-raising stage was sleep raising 2-3 hours sooner [57%]. The statistical test showed that the more sleep disorder, the less sleep consent [p<0.001]. Sleep disorders were more abundant in women [p<0.001]. There was no significant correlation between sleep disorder score and age, but with aging, the sleep complications will be increased [p<0.05]. Based on our results, the prevalence of sleep disorder in heart failure patients was higher than that of the general population. Regarding the importance of sleep in these patients providing good physical condition for sleep is necessary
