Beta-1-receptor blockade reduces heart rate, cardiac output, and arterial pressure while increasing peripheral vascular resistance. It is possible that beta blockers not only inhibit the core-to-peripheral re-distribution of body heat and cutaneous heat loss due to vasodilation after anesthesia induction but also reduce the convective transfer of heat from the ...

BACKGROUND: Neuraxial anaesthesia improves tissue perfusion and tissue oxygen tension. Vasodilation induced by this technique may result in hypotension requiring the administration of vasoactive drugs. The use of peripheral vasoconstrictors might counteract the improved tissue perfusion and its potentially beneficial effects. We therefore investigated the effect of i.v. norepinephrine and ...

Hypotension after spinal anaesthesia is a common and important complication at caesarean delivery. Skin conductance monitoring has been shown to predict post-spinal hypotension in elderly patients and may be a rapid, non-invasive means of predicting risk in the obstetric population. Women having elective caesarean delivery were included in this observational ...

Takayasu's arteritis is a rare form of nonspecific obliterative panarteritis of unknown aetiology. Anaesthesia for patients with Takayasu's arteritis is complicated by severe uncontrolled hypertension leading to end-organ dysfunction, stenosis of major blood vessels affecting regional circulation, and difficulties in the monitoring of arterial blood pressure. The anaesthetic approach for ...

Landiolol is a new ultra-short-acting beta 1-selective adrenoreceptor antagonist, which is metabolized rapidly by plasma cholinesterase (PCHE). Metoclopramide has been shown to inhibit PCHE in vitro. Therefore, metoclopramide might prolong beta blocking effects of landiolol and spoil its ultimate-short-acting property. Just before induction of anesthesia, gynecological patients were randomly assigned ...

Photoplethysmography (PPG), i.e. pulse oximetric wave, is a non-invasive technique that is used in anaesthesia monitoring primarily to monitor blood oxygenation. The PPG waveform resembles that of the arterial blood pressure but instead of pressure it is related to the volume changes in the measurement site and hence contains information ...

In many hospitals, emergency physicians commonly initiate invasive positive-pressure ventilation. To review common patient- and ventilator-related factors that can promote hemodynamic instability during and after endotracheal intubation. Venous return is proportional to mean systemic pressure (Pms) minus right atrial pressure (Pra). Endotracheal intubation with positive-pressure ventilation often reduces Pms while ...
