Intervention / Treatment |

Experimental: combined general/epidural anesthesia
epidural catheter was inserted in group GE at T8/9, T9/10, or T10/11 interspinous space with a 17-gauge Tuohy needle in lateral decubitus position and advanced 5 cm cephalad.
Epidural analgesia was maintained using the patient-controlled analgesia technique.

Before the induction of anesthesia, epidural catheter was inserted in group GE at T8/9, T9/10, or T10/11 interspinous space with a 17-gauge Tuohy needle in lateral decubitus position and advanced 5 cm cephalad. . Epidural analgesia was maintained using the patient-controlled analgesia technique containing 250 mL of 0.2% ropivacaine and 2 μg/mL fentanyl with setting of 5 mL/hr for continuous infusion and 0.5 mL of bolus dose. Lockout time was set to 15 min. General anesthesia was induced with 2 mg/kg of propofol and 50 mg of rocuronium. After tracheal intubation, anesthesia was maintained with sevoflurane. All the patients were ventilated with controlled mode of 8 mL/kg of ideal body weight and respiratory rate was adjusted to maintain end-tidal carbon dioxide between 35-40 mmHg. |
Active Comparator: General anesthesia
Patients allocated to general anesthesia group did not receive epidural anesthesia.

Patients allocated to general anesthesia group and DID NOT receive epidural anesthesia. General anesthesia was induced with 2 mg/kg of propofol and 50 mg of rocuronium. After tracheal intubation, anesthesia was maintained with sevoflurane.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change of diaphragm movement using sonography (diaphragm inspiratory amplitude, diaphragm inspiratory and expiratory velocity)on postoperative day 1 and 2 from baseline (day before surgery)
Time Frame: on the day before surgery until postoperative day 2
|
The measurements of diaphragmatic motion were attained at the posterior surface of the diaphragm.
From the tracings on M-mode, the distance between echogenic lines (DIA) in cm and diaphragm inspiratory/expiratory velocity in cm.s-1 during quiet, deep, and sniff breathing were measured on the frozen images.
Three consecutive sonographic examinations were performed, and the highest value of three measurements was recorded
|
on the day before surgery until postoperative day 2
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in pulmonary function test on postoperative day 1 and 2 from baseline (day before surgery)
Time Frame: on the day before surgery until postoperative day 2
|
Spirometric measurements included vital capacity (VCIN), forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/FVC, peak expiratory flow rate (PEF), maximal midexpiratory flow rate (MMEF), tidal volume (VT), and expiratory residual volume (ERV)
|
on the day before surgery until postoperative day 2
