Abstract

The cardiac output and hemodynamic indices were measured by the bioimpedance method using NCCOM3 in 38 selected spinal anesthetic cases with 0.5% bupivacain. The authors observed MAP, HR, PFI, EDI, CI and SI changes before-and during spinal anesthesia. The results were as follows: The mean values for MAP before, 10 minutes and 30 minutes after spinal anesthesia were observed to be 96.18+/-14.25 and 9.45+/-14.89 mmHg. These values during spinal anesthesia were significantly decreased compared with the value before spinal anesthesia(P<0.01). The mean values for HR before, and 30 minutes after spinal anesthesia were observed to be 71.34+/-17.25 and 72.39+/-19,01 beat/min. The value during spinal anesthesia was significantly decreased compared with the value before spinal anesthesia(P<0.01). The mean value for PFI before and during spinal anesthesia were observed to be 306.55+/-75.63 and 285.47+/-73.60 1/sec/m2 . The value duing spinal anesthesia was insignificantly decreased compared with the value before spinal anesthesia.(P<0.05). The changes of mean values of EF, EDI and SI were insignificant statistically. The mean values for CI before and 30 minutes after spinal anesthesia were observed to be 3.49+/-1.02 and 3.11+/-0.86(1/min/m2) The value during spinal anesthesia was significantly decreased compared with the value before spinal Anesthesia(P<0.01)
