Abstract/OtherAbstract:
The use of a tourniquet for obtaining a bloodless field is an essential and accepted tool for extremity surgery. A prospective study was done on 30 adult patients undergoing elective limb surgery requiring tourniquet application for haemodynamic and End tidal CO2 (EtCO2) changes. After the induction of general anaesthesia a tourniquet was applied on the limb. There was gradual increase in heart rate & EtCO2 through out the whole period of tourniquet inflation. There was also significant increase of mean arterial pressure during the inflation period. At the end of surgery tourniquet was deflated. Tourniquet time was 76.83+/-16.94 minutes. After deflation of the tourniquet, heart rate & EtCO2 value increased & the values were maximum at 5 minutes. These values came down to the base line at 15 minutes. There was significant decrease of mean arterial pressure (MAP) at 5 minute; it also came to the base at 15 minute. These changes are usually benign but can be significant in patients with co-existing cardiovascular & intracranial diseases. In conclusion, we recommend the haemodynamic and End tidal CO2 monitoring as well as rapid fluid infusion along with hyperventilation for 15-30 minutes after deflation of tourniquet.
