Circulatory changes produced by the Valsalva maneuver in normal subjects, patients with mitral stenosis, and autonomic nervous system alterations.
The cardiac output has been measured during the immediate post-Valsalva maneuver recovery period in normal subjects, patients with clinically significant mitral stenosis, and patients with alterations of the autonomic nervous system. When compared with the resting value, it was found that normal subjects had a decrease in cardiac output during the immediate post-Valsalva recovery period, while ...
متن کاملComparison of three methods of Valsalva maneuver, lidocaine, and Valsalva maneuvers along with administration of lidocaine to reduce the pain associated with administration of Propofol
Background: Propofol is commonly used in anesthesia practice because of its rapid recovery time, but pain upon injection is one of the unfavorable complications of this drug, which can cause both physical and mental discomfort for patients. Therefore, it is important to lower the pain on injection of Propofol in patients undergoing anesthesia. As a result, the current study was conducted in ord...
متن کاملComparison of the effectiveness of tourniquet and Valsalva maneuver in relieving pain caused by propofol injection to induce general anesthesia: A double-blind randomized clinical trial
Introduction: Propofol is one of the most common anesthetic drugs. Painful injection with a reported prevalence of 28 to 90% in various studies is one of the problems of taking Propofol. The present study investigated the effect of performing the Valsalva maneuver and tourniquet twisting on pain intensity and hemodynamic changes. Materials and Methods: This clinical trial was performed on 105 p...
متن کاملThe effects of the Valsalva-like maneuver upon the circulation in normal individuals and patients with mitral stenosis.
A Valsalva-like maneuver was performed during cardiac catheterization by a normal group of individuals and a group of patients with acoustic evidence of mitral stenosis. The latter group was subdivided according to its response to the maneuver. The mild group, like the normal group, showed an "overshoot" of blood pressure and a bradyeardia in the post-straining period, whereas the severe mitral...
متن کاملThe emphysema response to forced straining (Valsalva's maneuver).
R ECENTLY there has been a renewed interest in the physiologic effects of forced straining (Valsalva's maneuver). Particular emphasis has been placed on the blood pressure changes during and immediately after forced straining in an attempt to define more accurately the diagnosis of certain circulatory abnormalities, particularly hemodynamically significant mitral stenosis and the presence of co...
