Is preoperative testing inconsistent with published guidelines and rarely changes management?
The majority of elective surgical patients undergo preoperative testing. Non-compliance with guidelines ranged from 5 to 98%. The results of most tests were normal and influenced management in only 2.6% of cases.
These data do not support the contention that normal-to-borderline elevated pHo of healthy subjects are heritable and under major genetic influence. They suggest that E and C are far more important than A in determining pHo variance. Furthermore, they provide no evidence of a relationship of pHo with pACE and PAI-1:ag.
