Brief Summary:
Lymphatic venous anastomosis could be applied on patients suffering from limb lymphedema after surgery or radiotherapy. The particular pathophysiology leads unconventional fluid treatment strategy and changes in urine output. Hemodynamic monitors shows the benefits in perianesthetic care in fluid maintenance and decrease postanesthetic complication.
Invasive hemodynamic monitors, such as arterial line and FlowTrac, have risks of hematoma, infection, nerve injury in puncture site. In this study, photoplethysmography is applied comparing with conventional mean arterial pressure for perianesthetic hemodynamic optimization in bispectral index (BIS)-guided target-controlled infusion sedation on lymphatic venous anastomosis.

Detailed Description:
After allocation, patients would be assigned to Standard group or ClearSight group. All patients will be sedative with BIS-guided Propofol/Alfentanil Target-Controlled Infusion. The BIS will be maintained between 40-70 with electromyography(EMG) \< 30%. Ce(effect site concentration) of Propofol is adjusted according to BIS score. Ce of Alfentanil is adjusted between 15-75 ng/ml. Patients have spontaneous respiration during the procedure with O2 simple mask. If the oxygen saturation by pulse oximetry(SpO2) \< 95%, prescribe chin lift first. Nasopharyngeal airways is given if chin lift can not improve the saturation. Crystalloid, usually Lactate Ringer, is infused with the rate 4ml/kg/hr. The goal of Standard group is to maintain mean arterial pressure(MAP) \> 60%. If MAP \< 60%, 3ml/kg crystalloid is challenged in 10 minutes. If MAP still less than 60% after the second fluid challenge, Ephedrine 4-8mg iv is prescribed. ClearSight group is to maintain stroke volume(SV). If SV decreases more than 10%, 3ml/kg crystalloid is challenged in 10 minutes. If MAP still less than 60% after the second fluid challenge, Ephedrine 4-8mg iv is prescribed.
