Robotic Esophagectomy

Esophagectomy

The investigators will enroll adult patients who will undergo robotic esophagectomy under general anesthesia. The oxygen reserve index will be monitored continuously during anesthesia. The postoperative complications will be recorded after surgery.

Strategies to Reduce Postoperative Pulmonary Complications in Robot-assisted Esophagectomy: Intraoperative Monitoring of Oxygen Reserve Index

The investigators will monitor the oxygen reserve index during anesthesia.

The investigators will observe and record the occurrence of the postoperative pulmonary complications.

The patients who are diagnosed with multiple-trauma and have blood test in an emergency room. The patients with multiple-trauma are defined as the patients who have trauma in more than two regions.

Trauma

The blood samples of the patients who agreed on this research are obtained in order to check their inflammatory response factor, and then their medical records are checked to find their initial ABGA result, lactate, C-reactive protein(CRP) known as initial inflammatory response, and procalcitonin.
A patient's whole blood is collected in the tube with ethylene diaminetetracetic acid (EDTA) treatment. A modified method of Boyum's technique is applied so as to separate polymorphonuclear neutrophils. The separated polymorphonuclear neutrophils is collected so as to check apoptosis. And then, in the separated plasma, interleukin(IL)-6 and tumor necrosis factor(TNF)-α are measured, and its correlation with oxygen saturation will be analyzed.
