A Simple Apparatus for Intratracheal Anæsthesia

A Combined Manometer and Safety Valve for Intratracheal Anæsthesia

capable of accurate adjustment and dosage, at the same time simple in construction, and as far as possible reliable in its action, they started experimenting in March of this year. The first piece of the apparatus to be taken in hand was the safety valve. Those familiar with the intratracheal method of administering anaesthetics well know that an efficient safety valve is a sine qua non. Two ty...

A Simple and Inexpensive Method of Intra-Tracheal Anæsthesia

Stochastic Dynamics of Anæsthesia

Recent developments in the analysis of synchronization and directionality of couplings for noisy nonlinear oscillators are being applied to study the complex interactions between cardiac and respiratory oscillations, and brain waves (especially delta and gamma), during anæsthesia. It is found that marked changes occur in the inter-oscillator interactions during anæsthesia in both rats and human...

Interactions between cardiac, respiratory, and EEG-δ oscillations in rats during anæsthesia

We hypothesised that, associated with the state of anæsthesia, there exist characteristic changes in both cardio-respiratory and cerebral oscillator parameters and couplings, perhaps varying with depth of anaesthesia. Electrocardiograms (ECGs), respiration and electroencephalograms (EEGs) were recorded from two groups of 10 rats during the entire course of anæsthesia following the administratio...

The cardioprotective effect of vanillic acid on hemodynamic parameters, malondialdehyde, and infarct size in ischemia-reperfusion isolated rat heart exposed to PM10

Objective(s): Particulate matter (PM) exposure can promote cardiac ischemia and myocardial damage. The effects of PM10 on hemodynamic parameters, lipid peroxidation, and infarct size induced by ischemia-reperfusion injury and the protective effects of vanillic acid (VA) in isolated rat heart were investigated. Materials and Methods: Eighty male Wistar rats (250–300 g) were divided into 8 groups...
