The invention provides a flushing
system (1) configured to flush the
pericardial cavity (PC) of a patient, wherein the
system comprises: an infusion liquid outlet (4) to connect a first tube(20) having an infusion liquid lumen to guide a flow of infusion liquid from the
system to the
pericardial cavity, and an
effusion liquid inlet (6) to connect to a second tube (21) having an
effusion liquid lumen to guide the
effusion liquid flow from the
pericardial cavity to the system, a flow
rate control system to control the flow rate of the infusion liquid flow at the infusion liquid outlet (4) on the basis of
multiple sensor signals, wherein the flow
rate control system comprises: a
control unit (5) to provide a
control signal on the basis of the sensor signals, and a pump device (3) to pump infusion liquid to the infusion liquid outlet (4) at an infusion liquid flow rate, wherein the infusion liquid flow rate is adjustable by the
control signal of the
control unit (5) and wherein the sensor signals registered by the
control unit (5) comprise: an infusion liquid
signal representative for the infusion liquid flow to the pericardial cavity, an effusion liquid
signal representative for the effusion liquid flow rate from the pericardial cavity, a
blood volume signal generated by a
hematocrit sensor (12) representative for a
blood loss flow rate in the effusion liquid from the pericardial cavity, and a
pressure control signal representative for the pressure in the pericardial cavity generated by a
pressure sensor positioned inside or in connection with the first tube (20), the second tube (21) or the pericardial cavity. The invention also provides a method of monitoring the
blood loss volume or flow rate from the
pericardium based on
multiple sensor signals as well as, a method of treatment of postoperative cardiac patients in order to reduce the risk of cardiac
tamponade, reduce post-operative
blood loss and reduce the accumulation of blood and clots in the pericardial cavity, wherein the pericardial cavity of the patient is flushed with a flushing system according to the invention.
