The Study of the Arterial Blood Pressure Changes in Adult Patients Under Operated Through General Anesthesia

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 some 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.
