Summary

Increased intra-abdominal pressure(IAP) might influence on perioperative morbidity related to increased CVP, PVWP, SVR, PAP and decreased venous return and cardiac output. Prone position has been known to increase IAP. In clinical field, various apparatuses has developed to minimize IAP elevation during prone position operation. In this study, we would compare the changes of IAP and respiratory system compliance according to positional apparatus in prone position.

Detailed description

In clinical field, Wison frame, chest rolls and Jackson table have been widely used for prone position surgery. Among those apparatus, Jackson table has padded supports under the chest and pelvis, so that the abdomen can hang freely and prevent the abdominal compression. By reducing abdominal and thoracic pressure, Jackson table would reduce blood loss, and less effects on pulmonary mechanics. But few studies has known to compare IAP with other positioning apparatus such as Wilson frame or chest roll.

Conditions

• Prone Position

Interventions

Type	Name	Description
DEVICE	Jackson surgical table	After standard total intravenous anesthesia using propofol and remifentanil continous infusion, patients were turned to the prone position on a Jackson table with two padded supports on each side. The supports were positioned under the lateral chest and at the iliac crest.
DEVICE	Wilson frame	After standard total intravenous anesthesia using propofol and remifentanil continous infusion, patients were turned to the prone position on a Wilson frame. The supports were positioned vertically from shoulder to iliac crest.
DEVICE	Chest roll	After standard total intravenous anesthesia using propofol and remifentanil continous infusion, patients were turned to the prone position on a chest roll. The supports were positioned vertically from shoulder to iliac crest.
