Pulse oximeter plethysmographic waveform changes in awake, spontaneously breathing, hypovolemic volunteers.

BACKGROUND The primary objective of this study was to determine whether alterations in the pulse oximeter waveform characteristics would track progressive reductions in central blood volume. We also assessed whether changes in the pulse oximeter waveform provide an indication of blood loss in the hemorrhaging patient before changes in standard vital signs. METHODS Pulse oximeter data from fin...

Modeling the non-steady state respiratory effects of remifentanil in awake and propofol-sedated healthy volunteers.

BACKGROUND Few studies address the dynamic effect of opioids on respiration. Models with intact feedback control of carbon dioxide on ventilation (non-steady-state models) that correctly incorporate the complex interaction among drug concentration, end-tidal partial pressure of carbon dioxide concentration, and ventilation yield reliable descriptions and predictions of the behavior of opioids. ...

Mechanism of pupillary reflex dilation in awake volunteers and in organ donors.

BACKGROUND The mechanism of reflex pupillary dilation was investigated in eight patients who were declared brain dead after rupture of intracranial vascular malformations and in eight awake volunteers. The authors hypothesized that the reflex was primarily a spinal sympathetic reflex that would be blocked by topical application of the alpha1-adrenergic blocking agent dapiprazole and that it wou...

Population volume kinetics predicts retention of 0.9% saline infused in awake and isoflurane-anesthetized volunteers.

BACKGROUND In previous work, extravascular expansion was observed to be enhanced by isoflurane anesthesia in sheep when a crystalloid bolus was administered. The aim of the current study was to further elaborate these investigations to humans and to explore the use of population kinetics in the analysis of fluid shifts. METHODS Eleven healthy volunteers participated in two experiments each, e...

Ventilating Anterior Nasal Packing after Septoplasty

Anterior nasal packing after septoplasty is commonly employed by most of otorhinolaryngologists for haemostasis and splintage action. However it has complications which are usually manageable but rarely can become fatal particularly in high risk patients. Objectives: Present study was aimed to find out significance of ventilating nasal packing after septoplasty to minimize complications of nasa...
