show that the LC-NE system plays a modulatory role in the induction and emergence of intravenous general anesthesia induced by propofol and etomidate, both of which suppress LC neuronal activities through a cooperative mechanism. A point worth noting is that general anesthesia may not always be the best choice; depending on a patient’s clinical presentation, local … General anesthesia uses intravenous and inhaled agents to allow adequate surgical access to the operative site. TIVA total intravenous anaesthesia TNF tumour necrosis factor TOE transoesophageal echocardiography TOF train-of-four TPN total parenteral nutrition VF ventricular fibrillation VIE vacuum-insulated evaporator V/Q ventilation/perfusion VT ventricular tachycardia GCAPR 7/2/04 5:31 PM Page ix. Although total intravenous anaesthesia has advantages for some patients, the commonest technique used for maintenance of anaesthesia in the UK and Ireland remains the administration of an inhaled volatile anaesthetic. Chronic obstructive pulmonary disease and anaesthesia. Anaesthesia for the patient with respiratory disease. Duggappa DR, Rao G V, Kannan S. Anaesthesia for patient with chronic obstructive pulmonary disease. Continuing Education in Anaesthesia Critical Care & Pain, Volume 14, Issue 1, 1 February 2014, Pages 1–5. Group A received 15% magnesium sulphate 30 mg.kg −1 (from a blindly labelled vial) as a slow intravenous infusion prior to induction of anaesthesia and 10 mg.kg −1.h −1 by continuous infusion during surgery. Adjunct to surgery renders the patient unaware or unresponsive to pain stimuli Systemic effect on the CNS Intravenous agents act more rapidly producing unconsciousness in 20sec.thiopental, etomidate and propofol are used in induction of anaesthesia Here, Du et al. Recovery to 90% twitch height occurs in 40 to 50 minutes. Thiopentone and propofol are the intravenous induction anaesthetic agents used during general surgery. The study was done with an aim to compare the intra operative and the Post operative findings in Propofol and Thiopentone groups. Induction intravenous inhalational where IV access is difficult. The newer neuromuscular blocking drugs include vecuronium and atracurium. Update in Anaesthesia.

The same volume of isotonic saline was administered to the control group B. INTRAVENOUS ANAESTHESIA. E OMONGE Anaesthetic drugs - qualities. The locus coeruleus (LC)-norepinephrine (NE) system is involved in general anesthesia. Readily controllable Induction and recovery rapid General anaesthesia. Immediately after induction of general anesthesia, additional agents are necessary to maintain the anesthetic state since most induction agents have a brief duration of action. Vecuronium is a competitive neuromuscular blocking drug with a steroid nucleus. When maintenance of general anaesthesia is by intravenous infusion, this is referred to as total intravenous anaesthesia. A dose of 0.1 mg/kg has an onset time of 2 minutes and provides surgical paralysis for 20 minutes. This topic will discuss use of inhalation and intravenous (IV) agents during the maintenance phase of general anesthesia.
