Retrospective Evaluation of Effects of Preoperative Anaemia Treatment in Gynaecological and Obstetric Surgical Patients

OBJECTIVE: In anemic patients undergoing surgery, there is an increase in the requirement of blood transfusion, longer hospital stay and higher intensive care unit adimission. In this study we aimed to evaluate the efficacy of iv iron treatment before elective obstetric or gynecological operations retrospectively. METHODS: After obtaining approval of ethics committee, records of 5688 patients underwent either obstetric or gynecological surgery between January 1st of 2016 to December 31st of 2018 were documented retrospectively and 241 anemic cases were identified. Eighty-one anemic patients who did not receive any iv iron treatment preoperatively were excluded and 160 cases treated with either iv iron (either sucrose or ferric carboxy maltose) were included. The laboratory results including haemoglobin (Hb), MCV,MCH and serum iron binding capacities, ferritin, iron and transferrin levels were documented before (preoperative) and after iv iron treatment (postoperative 10(th) day) were collected from files. Difference between preoperative and postoperative Hb, MCV, MCH, TIBC, serum ferritin, iron and transferrin levels of these cases were determined. RESULTS: In 97 obstetric cases, the differences of Hb, MCV, MCH, serum iron, ferritin, iron binding capacity values before surgery and postoperative 10(th) day were respectively found as 1.3 g dL(−1) (p=0.000); 1.9 fL (p=0.000); 0.3 pg (p=0.01); 44.4 μg dL(−1) (p=0.008); 85.9 μg L(−1) (p=0.009); 211.7 μg dL(−1) (p=0.001). In 63 gynecologic cases, same measurements were evaluated and similar differences in Hb, MCV, MCH, serum ferritin and transferrin saturation values were 1.25 g dL(−1) (p=0.000); 2.2 fL (p=0.000); 0.8 pg (p=0.000); 215.6 μg L(−1) (p=0.002); 41.5% (p=0.044). Two obstetric patients and 7 gynaecologic patients were transfused erytrocyte suspensions after surgery. CONCLUSION: Efficacy of preoperative iv iron therapy in gynaecologic-obstetric patients with IDA has been demonstrated and its importance has been revisited once again.
