BACKGROUND Although photoplethysmography and cerebral state index (CSI) have been used as indices in monitoring vital signs perioperatively, there are only a few reports comparing the performance of photoplethysmography with CSI in monitoring anaesthesia depth. The aim of the present study was to clarify features of photoplethysmography in monitoring balanced general anesthesia compared with CS...

trachea [2]. For this reason, fibreoptic endotracheal intubation is advisable. Ljunghall and colleagues showed that patients with HPT who were apparently asymptomatic preoperatively did not have defects of their neuromuscular transmission that were of clinical significance [5]. In asymptomatic pHPT neither consistent abnormality of neuromuscular transmission nor abnormal muscle structure was fo...

Approach Eighteen New Zealand white rabbits, undergoing surgical catheterisation of the bilateral carotid and internal jugular vein, were used in this study. In group I (propofol), anaesthesia was maintained with an intravenous (iv) infusion of propofol at a rate of 0.7 mg/kg/min and interval iv fentanyl. In group II (isoflurane), the end-tidal concentration was adjusted to 1.0 minimum alveolar...

Evaluation of the Effect Kinesio Taping on Plantar Arch Index Children with Spastic Diplegic Cerebral Palsy

The dynamics of the cerebral vascular response to blood pressure changes in hypertensive humans is poorly understood. Because cerebral blood flow is dependent on adequate perfusion pressure, it is important to understand the effect of hypertension on the transfer of pressure to flow in the cerebrovascular system of elderly people. Therefore, we examined the effect of spontaneous and induced blo...

BACKGROUND AND PURPOSE This study aimed to monitor cognitive performance during a 3-year period in subjects with bilateral asymptomatic severe internal carotid artery stenosis and to explore the role of cerebral hemodynamics and atherosclerotic disease in the development of cognitive dysfunction. METHODS One hundred fifty-nine subjects with bilateral asymptomatic severe internal carotid arter...

BACKGROUND AND PURPOSE The effect of antihypertensive drugs on autonomic neural control of the cerebral circulation remains unclear. This study was designed to compare middle cerebral artery mean blood velocity responses to acute hypotension with and without alpha(1)-adrenoreceptor blockade (Prazosin) in young, healthy humans. METHODS Acute hypotension was induced nonpharmacologically in 6 he...

BACKGROUND AND PURPOSE A mathematical model has previously been introduced to estimate noninvasively intracranial pressure (nICP). In the present multicenter study, we investigated the ability of model to adapt to the state of cerebral autoregulation (SCA). This modification was intended to improve the quality of nICP estimation and noninvasive assessment of pressure reactivity of the cerebrova...
