The study examined the relationship of intraoperative hypotension (a drop in blood pressure during surgery) to serious cardiac events and kidney damage after pancreatic and small bowel surgery. The research included 1,846 patients operated on between January 2018 and December 2023, with their mean arterial pressure continuously monitored. The results showed that acute kidney injury progressively increased as blood pressure fell, while serious cardiac events followed a different pattern with a critical point around 65 mmHg. The most important metric was absolute maximum pressure change, which maintained statistical significance for both complications at all thresholds tested. The study found that cardiac events require a higher threshold for protection (MAP < 65 mmHg) than kidney damage (MAP < 60 mmHg), suggesting the need for more stringent blood pressure monitoring and control during major operations to protect various organs.
