Extreme blood loss in cancer surgery: is it a verdict to the patient or a challenge to the staff?

Abstract

Background. The development of anesthesiology allows performing combined operations in patients with locally advanced malignant tumors. A logical companion of aggressive cancer surgery is a massive blood loss, which can be so pronounced that it poses a threat to the life of the patient. Objective. The presented experience is an example of transformation of a nearly fatal situation into a curable one and can be useful in choosing an active treatment strategy in most desperate situations. Methods. This research includes 25 patients with the blood loss of 20 liters or more during surgery. Results. The median ratio of infusion to blood loss was 133%, and the ratio of the infusion to all fluid losses amounted to 118%. In 100% of cases, catecholamines were used to support the blood circulation: one drug used in 12% of observations and two to five drugs used in 88% of observations. 2 patients died during the operation. 5 patients died in the early postoperative period from multiple organ failure. The cause of death of another 5 patients was septic complications before the 28th post-op day. Discussion. Performing operations accompanied by acute massive blood loss requires an effective anesthetic support. Conclusions. Enforcement of certain diagnostic and therapeutic conditions (stage construction of anesthesia, hemodynamic and laboratory monitoring, adequate venous access, rational infusion, timely use of catecholamines, using cell-saver device) in the majority of cases allows completing the operation with the surgical control of hemostasis and successfully enduring traumatic and complicated surgery in half of cases.
