Brief Summary

Adequate and balanced fluid resuscitation is one of the cornerstones of intraoperative patient management. Over-resuscitation leading to positive fluid balance is associated with increased postoperative mortality and morbidity. Invasive and non-invasive technologies can be used for the adequacy of intraoperative fluid therapy. Lung ultrasonography (LUS) is a safe and accurate bedside imaging method. LUS, which is frequently used in the diagnosis of postoperative hypoxemia, has also begun to be preferred for fluid management in intensive care units.

Conditions

Intraoperative Fluid Management

Outcome Measures

Primary Outcomes (1)

• LUS

  peroperative

Secondary Outcomes (9)
