Abstract

A retrospective study was conducted on patients subjected to laparoscopic myomectomy at our institution from January 2017 to December 2018 to identify predictive factors of blood loss. Two multiple regression models were run to predict intraoperative blood loss and haemoglobin drop. Predictors of an increased intraoperative blood loss and haemoglobin drop were the presence of three-four fibroids at ultrasound (+47 ml, p =.01; +0.58 g/dl, p =.05) and increased operative time (r = 0.57, p =.01; r = 0.01, p <.01), while predictors of a reduced intraoperative blood loss and haemoglobin drop were epinephrine injection (–50 ml, p <.01; −0.42 g/dl, p <.01), FIGO7 (–87 ml, p <.01; −0.85, p =.01), and FIGO6 (–35 ml, p <.01; −0.44, p =.02) fibroids at the ultrasound. Preoperative ultrasound evaluation is crucial in identifying patients at higher risk for blood loss, which could benefit from optimising haemoglobin values. The injection of diluted epinephrine could be proposed in selected high-risk patients. In the clinical practice, a tailored approach based on fibroids’ ultrasonographic characteristics should be implemented to optimise preoperative Hb values and evaluate the use of diluted epinephrine in selected cases, reducing blood loss and the potential related complications.Impact statementWhat is already known on this subject?
