Filter by:To record the digital data from monitoring instruments (standard patient monitor) containing cardiovascular system information, and from depth-of-anesthesia monitoring modules (Bispectral index, Entropy module, Surgical Plethysmography Index, Analgesia Nociception Index) containing neurological system information captured in the patient monitor, as well as the physiological data regarding anesthetic dosage, respiratory gas analysis and the standard monitoring requirement of anesthesia. The investigators also record the precise time points of detail surgical steps during the laparoscopic cholecystectomy. Clinical data collected from these monitoring instrument will be used to gain more understanding of the complex interaction between anesthetic effect, surgical procedure, autonomic response and drug modeling. The goal is to obtain the performance of each monitoring index in detail surgical steps.
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.
The purpose of this study is to determine whether increasing cardiac output by a combination of intravenous fluids and inotropic drugs can reduce mortality and morbidity in radical cystectomy operations.
