بررسی تغییرات فشار خون شریانی در بیماران بالغی که با القاء بیهوشی عمومی تحت عمل جراحی قرار می گیرند

The aim of this study was to determine the arterial blood pressure    changes in adult patients under operated through general anesthesia one    of the training hospitals in Iran University of Medical Sciences.            This study was a comparative analytic descriptive study , and was    performed in one of the related hospitals in Iran University of Medical    Sciences in 1991. In this research , arterial blood pressure of forty patients    was recorded using the mercurial sphygmomanometer , stethoscope and    direct observation. The mentioned data were analyzed through paired    t.test.            The results indicated that the means of the differences in the mentioned    patient systolic blood pressure prior to induction of anesthesia,    during anesthesia, and immediately after extubation were 10, 18.62 and    11 mmHg respectively. Also  the means of the differences in the same    patients diastolic B.P in these stage in comparison with their B.P in the ward    were 3.25 , 5.67 , 8.87 and 6.62, respectively and the paired t.test showed    the meaningful differences.           The results obtained from the statistical analysis showed the patients    blood pressure change in all stages ; prior to and after induction of    anesthesia , during operation and immediately after the extubation.
