Background  The bone cement implantation syndrome (BCIS) is a frequent and potentially disastrous intraoperative complication in patients undergoing cemented hip arthroplasty. Several risk factors have been identified, however randomized controlled trials to reduce the incidence of BCIS are still pending. We hypothesized that goal-directed hemodynamic therapy guided by esophageal Doppler monitoring (EDM) may reduce the incidence of BCIS in a randomized, controlled parallel-arm trial.    Methods  After approval of the local ethics committee, 90 patients scheduled for cemented hip arthroplasty at the Medical Center – University of Freiburg were randomly assigned to either standard hemodynamic management or goal-directed therapy (GDT) guided by an esophageal Doppler monitoring-based algorithm. The primary endpoint was the incidence of overall BCIS including grade 1–3 after cementation of the femoral stem. Secondary endpoints included cardiac function, length of hospital stay and postoperative complications.    Results  Ninety patients were finally analyzed. With regards to the primary endpoint, the overall incidence of BCIS showed no difference between the GDT and control group. Compared to the control group, patients of the GDT group showed a higher cardiac index before and after bone cement implantation (2.7 vs. 2.2 [l●min − 1 ●m − 2 ]; 2.8 vs. 2.4 [l●min − 1 ●m − 2 ];  P  = 0.003,  P  = 0.042), whereas intraoperative amount of fluids and mean arterial pressure did not differ.    Conclusions  The implementation of a specific hemodynamic goal-directed therapy did not reduce the overall incidence of BCIS in patients undergoing cemented hip arthroplasty.    Trial registration  This randomized clinical two-arm parallel study was approved by the local Ethics Committee, Freiburg, Germany [EK 160/15, PI: U. Goebel] and registered in the German Clinical Trials Register ( DRKS No. 00008778 , 16th of June, 2015).
