Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Principal hypothesis:

A low suction drainage (-50 mmHg) reduce a 25% the blood loss with respect a standard closed drainage (-700 mmHg) following total knee arthroplasty.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Secondary's hypothesis:

* It don't expect differences in:

1. Incidence of hematomas
2. Incidence in surgery wound infection
3. Time of immobilization
4. Duration of hospitalization
* The low suction drainage (-50 mmHg) will be more cost-effective than the standard closed drainage (-700 mmHg)

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Low suction drainage

In the experimental group the drainage catheter was connected to a modified DRENOFAST® system. This system consisted of a sterile plastic bottle with a holding capacity of 600 mL of fluid and a negative pressure of 700mmHg. It was hermetically closed and had two connections. The DRENOFAST® modification consisted of establishing an open connection between the bottle and a wall vacuum source (normally used to administer oxygen) placed next to the patient's bed. The 50 mmHg constant negative pressure of the bottle was maintained by the wall vacuum source and verified by flow meter.

Intervention Type DEVICE

In the experimental group the drainage catheter was connected to a modified DRENOFAST® system. This system consisted of a sterile plastic bottle with a holding capacity of 600 mL of fluid and a negative pressure of 700mmHg. It was hermetically closed and had two connections. The DRENOFAST® modification consisted of establishing an open connection between the bottle and a wall vacuum source (normally used to administer oxygen) placed next to the patient's bed. The 50 mmHg constant negative pressure of the bottle was maintained by the wall vacuum source and verified by flow meter. Duration: Drains were removed after bleeding had ceased (48-72h).

High suction drainage

The standard DRENOFAST® system was used in the control group, and the initial negative pressure was 700 mmHg.

Group Type ACTIVE_COMPARATOR

High pressure suction drainage

Intervention Type DEVICE

In order to mask the type of intervention from the patient and the investigators, both drainage systems had two drain catheters. One catheter allowed the blood to flow from the wound to the bottle. The second catheter connected the bottle to the vacuum source. In the experimental arm the second catheter was open, while in the control group it was closed. So that the system used could not be distinguished, the connection of the second catheter to the bottle was covered with opaque adhesive tape.Drains were removed after bleeding had ceased.
