Reduction in perioperative blood loss using ultrasound-activated scissors during tumour surgery.

The aim of this study was to compare the effectiveness of Harmonic Focus+ scissors with the conventional surgical method regarding surgical blood loss and transfusion of blood products in the surgical treatment of head and neck tumours. In a retrospective study, the intraoperative blood loss, number of units of transfusion products given, operating time, and inpatient length of stay of 74 patients with squamous cell carcinoma were compared. Patients who underwent classic tumour surgery were compared with a group treated with Harmonic Focus+ scissors. A significantly lower intraoperative blood loss (496.15⬰ml vs 1096.0⬰ml, respectively; P⬰=⬰0.002) and shorter operation time (436.89 minutes vs 493.13 minutes, respectively; P⬰=⬰0.030) were achieved using the Harmonic Focus+ scissors when compared to the classic tumour surgery. Additionally, fewer units of blood products needed to be transfused (administration of red cell concentrates, P⬰<⬰0.001) and the length of stay in the intensive care unit was shorter for patients treated with the Harmonic Focus+ scissors (P⬰=⬰0.009). The study results indicate that the use of Harmonic Focus+ scissors during surgery for cancer of the oral cavity and pharynx is a safe and cost-effective method. This is of paramount importance during a pandemic when medical resources are scarce, including access to blood reserves.
