Key result
Hypotensive epidural anaesthesia resulted in significantly better radiographic scores for acetabular cement-bone fixation compared to normotensive general anaesthesia (p<0.02).

Does hypotensive epidural anaesthesia improve the quality of the cement-bone interface in patients undergoing total hip arthroplasty?
p-value: p=<0.02
Hypotensive epidural anaesthesia facilitates better penetration of cement into bone during total hip arthroplasty compared to normotensive general anaesthesia.
Cs et al. (1991) conducted a cohort in Total hip arthroplasty (n=40). Hypotensive epidural anaesthesia vs. Normotensive general anaesthesia was evaluated on Quality of the cement-bone interface assessed by radiographic scores (p=<0.02). Hypotensive epidural anaesthesia resulted in significantly better radiographic scores for acetabular cement-bone fixation compared to normotensive general anaesthesia (p<0.02).
