Organ perfusion during controlled hypotension.
Relatively short periods of unwanted hypotension, such as those associated with "shock" states, may be followed by irreversible organ damage. In contrast, controlled hypotension is rarely followed by organ damage, although minor reversible changes in function may occur (Rollason and Hough, 1960; Enderby, 1961; Linacre, 1961). The usual explanation for this paradox is that in the former situatio...
متن کاملAutoregulation of cerebral blood flow during controlled hypotension in baboons.
The effect of graded, progressive hypotension on the autoregulation of cerebral blood flow was studied in anaesthetised baboons. Progressive hypotension was produced over a period of four to five hours, either by graded haemorrhage or by the administration of increasing concentrations of hypotensive drugs. During haemorrhagic hypotension autoregulation was maintained until the mean arterial pre...
متن کاملControlled hypotension during operation for coarctation of the aorta.
Since 1948 61 patients have been operated on for coarctation of the aorta at the University Hospital, Copenhagen. The technical problems of this operation are largely due to the high blood pressure proximal to the stenosis and in the highly developed and dilated collaterals which are forced to act as a by-pass round the stenosis. These dilated and fragile vessels, particularly the intercostal a...
متن کاملClevidipine for controlled hypotension during spinal surgery in adolescents.
INTRODUCTION Clevidipine is an ultra-shorting acting, intravenous calcium channel antagonist of the dihydropyridine class. Metabolism by blood and tissue esterases results in a half-life of 1-2 minutes thereby allowing easy titration by i.v. administration. We present preliminary experience with this novel agent to provide controlled hypotension (CH) in a cohort of adolescents undergoing poster...
متن کاملEffects of propranolol in a case of orthostatic hypotension.
In a hypertensive patient with orthostatic hypotension, the changes in several haemodynamic indices with respect to posture were evaluated. In the upright position, systemic blood pressure was reduced as compared with the supine position, and peripheral vasodilation was present, as shown by an increase in Jantsch's index of the impedance plethysmographic tracings. Systolic time intervals remain...
