also found that the incidence of hypotension was 10.5% (6/57) in patients with baseline PI ≤3.5 and 71.42% (45/63) in patients with baseline PI >3.5 which was clinically and statistically highly significant (p < 0.001).[ 5 ] Varghese RV found that the incidence of hypotension in group 1 (PI >3.5) was 86.67% whereas in group 2 (PI ≤3.5) was 6.67% which was highly significant (p < 0.05).[ 6 ] George et al . found that the incidence of hypotension was 66.7% among the study subjects and they concluded tha
