Perioperative Monitoring

Many articles have reported that intraoperative low mean artery pressure (MAP) or low systolic blood pressure (SBP) impacts on organs’ function and patients’ outcomes perioperatively. On the contrary, what type of blood pressure should be obtained still needs to be clarified. In our paper, we compared the influencing factors of MAP and SBP, and mathematical formula, arterial pulse contour calculation, and cardiovascular physiological knowledge were adopted to discuss how blood pressure can effectively reflect tissue perfusion and hemodynamic abnormality perioperatively. We concluded that MAP can reflect cardiac output change sensitively and SBP can reflect stroke volume change sensitively. Moreover, SBP can reflect the early hemodynamic changes, organs’ perfusion, and heart systolic function. Compared with MAP, perioperative monitoring of SBP and timely detection and treatment of abnormal SBP are very important for the early detection of hemodynamic abnormalities.

Histological Damage

Subcutaneous injection of 40 mg/kg isoproterenol is followed within 2 minutes by a fall in blood pressure and peripheral resistance, by tachycardia, and by an increase in cardiac output. It seems likely that these hemodynamic changes are a consequence of a direct action of isoproterenol on the myocardium. Isoproterenol also causes a significant increase in the oxygen consumption of the rats. The increased oxygen demand of the tissues may play a role in maintaining the hemodynamic changes for periods of more than an hour after isoproterenol. Signs of histological damage in the myocardium begin to appear without affecting the function of the cardiovascular system, as measured by the tests used.

Hemodynamic Changes

Cardiodynamic and hemodynamic reactions to emotion-eliciting film sequences were investigated. Thirty-two healthy subjects (12 women, 20 men) were randomly assigned to one of two groups. In the first group, anger was induced using selected scenes of the film “Ragtime.” In the second group, scenes of the film “The Shining” were chosen to elicit fear. A documentary film was used as a baseline stimulus in both groups. EKG, impedance cardiography, and blood pressure were continuously monitored. The two emotional conditions elicited significant differential changes in subjective ratings and cardiovascular indices. Fear was associated with decreased cardiac output, increased total peripheral resistance, and a reduction in stroke volume and myocardial contractility. Anger was associated with an increase of cardiac output and small changes in total peripheral resistance. These results support the hypothesis that discrete emotions such as fear and anger elicit differential patterns of physiological responses.
