Fifty patients underwent baseline measurement of heart rate variability and were then assigned according to haemodynamic events (hypotension or bradycardia) after standardised induction of anaesthesia into ~stable~ (n = 39) and ~unstable~ patients (n = 11). Unstable patients had significantly lower baseline total power. Total power < 500 ms2 x Hz(-1) was associated with high sensitivity and specificity for the prediction of hypotension or bradycardia. Prospectively, 29 patients with total power < 500 ms2 x Hz(-1) were compared with 21 patients with total power > 500 ms2 x Hz(-1). Differences were found in the lowest mean arterial pressure and heart rate after induction of anaesthesia. We conclude that the pre-operative total power of heart rate variability in high risk patients may indicate the occurrence of haemodynamic events with high sensitivity and specificity. Heart rate variability may be a suitable tool to identify patients at high risk of a haemodynamic event and may be used to indicate need for intensive monitoring and, perhaps, prophylactic treatment. ------>tmu_sno=None ------>sno=13107 ------>authors2=Kuok CH ------>authors3=Kuo TBJ ------>authors4=HSU YW ------>authors5=Tsai PS ------>authors6= ------>authors6_c= ------>authors=Huang CJ ------>delete_flag=0 ------>SCI_JNo=None ------>authors2_c= ------>publish_area=0 ------>updateTitle=Does heart rate variability predict hypotension and bradycardia after induction of general anaesthesia in high risk cardiovascular patients? ------>language=2 ------>check_flag=None ------>submit_date=None ------>country=None ------>no=5 ------>patent_SDate=None ------>update_bywho=None ------>publish_year=2006 ------>submit_flag=None ------>publish_month=5 |
