Why the study?
Does intraoperative hypotension or post-induction hypotension increase the risk of post-operative organ complications in surgical patients?
Does intraoperative hypotension or post-induction hypotension increase the risk of post-operative organ complications in surgical patients?
Intraoperative hypotension (MAP ≤ 65 mmHg) is associated with post-operative organ complications, though comparisons with post-induction hypotension are complicated by differences in cumulative duration.
IOH but not PIH was associated with post-operative complications; leaves open whether duration-specific IOH thresholds warrant prospective trials.
The presence of IOH defined as MAP ≤ 65 mmHg is relevant to post-operative organ complications, the presence of PIH does not appear to be of such significance. Because cumulative duration of PIH and IOH differs significantly, especially in long-lasting procedures, direct comparison of the influence of PIH and IOH on outcome separately may be biased and should be taken into account in data interpretation. Further research is needed to deeply investigate this phenomenon.
