Intraoperative blood salvage (IOS), also known as cell salvage, is a specific type of autologous blood transfusion. Specifically IOS is a medical procedure involving recovering blood lost during surgery and re-infusing it into the patient. It is a major form of autotransfusion.
Autotransfusion is a process wherein a person receives their own blood for a transfusion, instead of banked allogenic (separate-donor) blood.There are two main kinds of autotransfusion: Blood can be autologously "pre-donated" (termed so despite "donation" not typically referring to giving to one's self) before a surgery, or alternatively, it can be collected during and after the surgery using ...
The process is commonly known as "cell-saver" and is considered far superior to the use of blood from a donor, because it reduces the possibility of infection and provides more functional cells back to the patient. [1] Because the blood is recirculated, there is no limit to the amount of blood that can be given back to the patient. [2]
The intraoperative consultation is the name given to the whole intervention by the pathologist, which includes not only frozen section but also gross evaluation of the specimen, examination of cytology preparations taken on the specimen (e.g. touch imprints), and aliquoting of the specimen for special studies (e.g. molecular pathology ...
Newer, more advanced thrombapheresis machines can filter white blood cells during separation. [citation needed] For example, with marginally acceptable whole blood (white blood cells: < 10,000/mm³; platelets: > 150,000/mm³), a dose (3×10 11) of platelets comes with about 2×10 10 white blood cells. This can seriously damage the patient's health.

This type of hematology analyzer utilizes both Coulter's principle and flow cytometry to determine the granularity, diameter, and inner complexity of the cells. Using hydrodynamic focusing, the cells are sent through an aperture one cell at a time. During this, a laser is directed at them, and the scattered light is measured at multiple angles.
In a hybrid operating room the anatomy can be updated and imaged in real time. 3D images can be fused and/or overlaid on live fluoroscopy or the endoscope. (Real-time image guidance in laparoscopic liver surgery: first clinical experience with a guidance system based on intraoperative CT imaging. [19]) Crucial anatomy like vessels or a tumor ...
