This study was to investigate the influence of bone cement implantation on haemodynamics and the preventive effect of epinephrine hydrochloride on pulmonary embolism in elderly patients with cemented semihip replacement. 128 patients were retrospectively analyzed. The patients were treated with (group A, 64 cases) or without (group B, 64 cases) epinephrine hydrochloride saline. The monitoring indicators included systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), heart rate (HR), and pulse oxygen saturation (SPO 2 ). The indicators of the two groups were compared before and 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10 minutes after bone cement implantation. Analysis of variance and SNK-q test were used for the statistical analysis. Blood pressure and SPO 2  of group B decreased with statistical difference ( P  < 0.05) and HR increased without statistical significance, comparing with those of group A. In group A, SBP, DBP, MAP, HR, and SPO 2  after bone cement implantation did not change significantly at each time point comparing with before implantation ( P  > 0.05). Bone cement implantation has significant influence on hemodynamics in elderly patients with hemiarthroplasty. Flushing the bone marrow cavity with saline epinephrine hydrochloride is an effective measure to reduce the incidence of bone cement pulmonary embolism.
