Overview
Brief Summary
The Perfusion Index (PI) is the ratio of the pulsatile to the non-pulsatile signal obtained from the pulse oximetry wave-form that is incorporated in several modern pulse oximeter monitors available in operating theatres.
It decreases with vasoconstriction and increases with vasodilatation, and several studies have suggested that the PI may be a sensitive estimate of the level of hemodynamic activity, as it indicates the status of the microcirculation which is densely innervated by sympathetic nerves, so our purpose is to check the findings of previous studies and to decide whether PI can be used as noninvasive parameter to measure hemodynamic response or not.
PI has been used to predict low blood pressure, identify early success indicators of central and peripheral nerve block effect assessment, evaluate systemic vascular resistance, indicate the success of sympathectomy and identify the incidence of hypotension after spinal anaesthesia
In our study ,We will check PI as non invasive parameter for hemodynamic response with the help of changes in perfusion index during Laryngoscopy
Recruitment of patients will start after the CTRI registration

Outcomes
Primary Outcomes
Measurement of hemodynamic response using perfusion index
Time Frame: baseline 0 minutes,during laryngoscopy - at the time of intubation , post intubation for 10 minutes, before reversal , during laryngoscopy- at the time of extubation ,post extubation for 10 minutes
Secondary Outcomes
- correlate change in hemodynamic parameters with perfusion index(baseline 0 minutes,during laryngoscopy - at the time of intubation , post intubation for 10 minutes, before reversal , during laryngoscopy- at the time of extubation ,post extubation for 10 minutes)
