Abstract

The cardiac output and hemodynamic indices were measured by the bioimpedance method using NCCOM; in 21 selected halothane anesthetic cases. The author observed MAP, HR, PFI, EDI, CI and SI changes before and during halothane anesthesia. The results were as follows; The mean values for MAP before and during halothane aneshtesia were observed to be 101.90+/-13.92, 89.67+/-9.22, 96.20+/-12.32, 123.76+/-19.17, 93.24+/-16.27, 90.62 +/-17.15, 96.05 +/-16.06 and 98.38+/-19.60 mmHg. Theae values 1 minute after thiopental injection and 30 minutes after halothane inhalation were significantly devreased compared with the value of preanesthesia(p<0.01 or p<0.05). The value after intubation was significantly increased compared with the value of preanesthesia(p < 0.01). The mean values for HR before and during halothane anesthesia were observed to be 81.86+/-16.79, 85.67+/-10.28, 83.43+/-1l.67, 108.86+/-17.0S, 93.7614.41, 81.05+/-11.02, 105.81+/-133.21 and 78.24+/-1l.59 beat/min. These values after intubation and 5 minutes after pancuronium injection were significantly increased compared with the value of preanesthesia(p<0.01). The mean values for PFI, EF, EDI, CI and SI during halothane anesthesia were(significantly) decreased compared with the value of preanesthesia.
