Brief summary
It has been proved that lithium carbonate can prolong slow wave sleep with few or no side-effects. The aim of the present study is to evaluate postoperative sleep quality of patients undergoing video assisted thoracic surgery taken 250mg lithium carbonate 6 hours after surgery.
Detailed description
This study is a prospective, randomized, controlled (randomized, parallel group, concealed allocation), double-blinded trial. All patients undergoing video assisted thoracic surgery during morning will be randomized 1:1 to the treatment intervention with lithium carbonate 250mg (Baoqing, Hunan, China) or calcium carbonate 500mg (Reneed, Beijing, China) 6 hours after surgery. The objective of the trial is to evaluate the lithium carbonate 250mg on the first postoperative night sleep quality. The patients received standardized general anesthesia supplemented by paravertebral nerve block. The ultrasound-guided approach for paravertebral nerve block was used with the patient in the lateral decubitus position, and the paravertebral nerve block was administered at the T4-T6 level according to the incision protocol at our center. General anesthesia for maintenance of propofol anesthesia, total intravenous anesthesia was administered by using propofol (Fresenius Kabi, Austria GmbH) at a plasma target concentration (Marsh pharmacokinetic model software) of 2.5-4 μg/ml. Remifentanil (0.2-0.5 μg/kg/min, Renfu, Yichang, China) was given to all patients during the operation. All patients accepted patient-controlled intravenous analgesia with 1 μg ml-1 sufentanil (Renfu, Yichang, China). Duration of sleep was defined as the duration of all bispectral index data below 80 in the 12 hours of monitoring (from 20:00pm to 06:00am).
