The patients were divided into two groups—a hypotension group and a normal group—based on the occurrence of intraoperative hypotension, which was defined as a mean arterial pressure < 65 mmHg and lasting ≥ 1 minute during the operation. The variables with a P value ≤ 0.1 in univariate regression analysis and clinically considered relevant variables were included in multivariate regression analysis in order to screen the risk factors for hypotension in these patients.Results: A total of 114 patients were included in the analysis. The incidence of hypotension was 54.4%. Old age was identified as the only risk factor for hypotension during hiatal hernia surgery.Conclusion: Old age is the only risk factor for intraoperative hypotension in patients undergoing laparoscopic hiatal hernia repair.Keywords: hiatal hernia, hypotension, risk factors
