Background The advent of sevoflurane, in to the field of inhalational anaesthesia has added an attractive choice to the anaesthesia armamentarium. In some respects, it combines the properties of halothane and isoflurane and overcomes the disadvantages of both.
Objectives The aim of the study is to evaluate its usefulness in prolonged surgeries calling for a high degree of cardiovascular stability in selected neurosurgical and cardiothoracic patients of our study.
Methodology This prospective study includes 15 Neurosurgical patients and 5 cardiothoracic patients. After adequate preparation induction of anaesthesia was done as shown. Maintance of anaesthesia was done with J-R (Jackson Rees) circuit in the three paediatric patients and use of closed circuit and Bains circuit alternately in adult patients to space the effect of sodalime on sevoflurane. All the patients were monitored for colour, Pulse, Non invasive blood pressure, Pulse Oximetry, Urine output and CVP as indicated.
Result Sevoflurane is an excellent agent for use in the above operations, providing good operating conditions with cardiovascular stability and rapid recovery even after such prolonged operations. However institution of pain management before termination of its anaesthetic effects is warranted to prevent post operative restlessness which in turn might provoke nausea and vomiting with dangerous and deleterious effects in these patients.
Conclusion From our study we conclude that sevoflurane is an excellent agent for use in prolonged surgeries calling for a high degree of cardiovascular stability,with added advantages of rapid and smooth recovery.
