Changes in cardiac index and total peripheral resistance index in all patients (A; n=54) and patients with hypotension after tourniquet deflation (B; n=9). Data are presented as mean with SD. T1: during 5 min before the lateral position for spinal anesthesia, T2: between 15 and 20 min after the end of local anesthetic injection into the subarachnoid space, T3: between 10 and 15 min after tourniquet inflation, T4: during 5 min before tourniquet deflation, T5: nadir within 10 min after tourniquet deflation. * P<0.001 compared to T1; ^‡ P<0.001 compared to T3; ^§ P<0.001 compared to T4; ^|| P<0.01 compared to T1; ** P<0.01 compared to T3; ^‡‡ P<0.05 compared to T2; ^{|| ||} P<0.01 compared to T4; ^¶P<0.05 compared to T3.
