BACKGROUND Intrathoracic pressure regulation (IPR) therapy has been shown to increase blood pressure in hypotensive patients. The potential value of this therapy in patients with hypotension secondary to trauma with bleeding is not well understood. We hypothesized that IPR would non-invasively and safely enhance blood pressure in spontaneously breathing patients with trauma-induced hypotension....
BACKGROUND Spinal anesthesia is a standard technique for cesarean section but can cause hypotension which may be related to venous pooling secondary to progesterone-induced decreases in vascular tone. This study investigated the use of a sequential compression mechanical pump with thigh-high sleeves with compression cycles timed to venous refilling. We hypothesized that this would recruit poole...
Two patients with profound dialysis-induced hypotension were seen, in both of whom sequential ultrafiltration and haemodialysis failed to alleviate their symptoms; in one bicarbonate dialysis similarly produced no improvement. The hypotension was frequently severe enough to necessitate premature termination of the dialysis. Haemofiltration was associated with almost total resolution of symptoms...
The impact on blood pressure of two vasodilating mechanisms, underlied by vascular smooth muscle hyperpolarization, was studied and compared to that induced by nitric oxide NO mechanism. Systemic blood pressure, after inhibitory intervention in arachidonic acid metabolism cytochrome P-450 inhibition by miconazole 0.5 mg/100 g b.w. , one of the hyperpolarizing pathways, did not change. After the...
