Fluid restriction neither increased nor was a risk factor for AKI. HES should be administered with caution in high-risk patients undergoing thoracic surgery.

BACKGROUND: Stroke volume variation (SVV) and pulse pressure variation (PPV) are used as indicators of fluid responsiveness, but little is known about the usefulness of these dynamic preload indicators in thoracic surgery, which involves an open thoracic cavity and 1-lung ventilation (OLV). Therefore, we investigated whether SVV and PPV could predict fluid responsiveness, and whether the thresholds of these parameters should be adjusted for thoracic surgery. METHODS: This was a prospective, cont

This study was performed to evaluate the effects of cryoanalgesia combined with thoracic epidural analgesia on pain and respiratory complications in patients undergoing thoracotomy. Ninety patients were prospectively randomised to epidural analgesia alone (n = 45) or epidural analgesia and cryoanalgesia combined (n = 45). We monitored the use of rescue pain medication and changes in forced vital capacity and forced expired volume in 1 s, and recorded pain and opioid-related side-effects during t

BACKGROUND: Postoperative delirium (POD) is one of messy complications related with increased mortality and hospital costs. Patients undergoing esophagectomy are more in danger of delirium than other kinds of surgeries. We investigated the impact of robot-assisted thoracoscopic esophagectomy on the incidence of POD compared with open transthoracic esophagectomy. MATERIALS AND METHODS: A retrospective review was completed for the patients who underwent esophagectomy from December 2, 2012 and Apri

Rapid crystalloid prehydration can affect CSF flow in the lumbar region, reducing cephalic spread of 0.5% isobaric tetracaine and delaying the time to reach the peak sensory level.

Age, operation name, preoperative lung injury, epidural analgesia, and ppoFEV1 can predict postoperative morbidity in thoracic surgery patients.

We assessed the roles of the protein kinase C (PKC) and the tyrosine kinase (TK) signaling pathways in regulating capacitative calcium entry (CCE) in human pulmonary artery smooth muscle cells (PASMCs) and investigated the effects of intravenous anesthetics (midazolam, propofol, thiopental, ketamine, etomidate, morphine, and fentanyl) on CCE in human PASMCs. Fura-2-loaded human PASMCs were placed in a dish (37 degrees C) on an inverted fluorescence microscope. Intracellular Ca2+ concentration ([

BACKGROUND: A high fraction of inspired oxygen (Fio2) is administered during one-lung ventilation (OLV). However, a high Fio2 is not physiologic and may lead to various complications. We hypothesized that continuous titration of Fio2 using the oxygen reserve index (ORI) reduces oxygen exposure compared to conventional management during OLV. METHODS: In this randomized, double-blinded trial, patients undergoing thoracic surgery were assigned to an ORI (n = 64) or a control group (n = 60). In the

Sugammadex reverses neuromuscular blockade by encapsulating steroidal neuromuscular blockers; therefore, it does not pharmacologically affect sedation levels. However, some clinicians avoid using it because of sudden unwanted acting out or patient arousal. Previous studies suggested sugammadex-induced awakening, but frontal muscle contraction after sugammadex administration compromised reliability of results obtained from EEG-based anesthesia depth monitoring tools like bispectral index (BIS). W

Background: Compared with blockers mounted on the endotracheal tube, (a conjugated blocker), studies about blockers that are independent of a single-lumen tube, (a separated blocker) are rare. This study's object was to find several characteristics about these new blockers.

Eleven year-old boy was scheduled for right encephalo-duro arterial synangiosis (EDAS). He received left EDAS 4 months ago, and there was no problem during the perioperative period. Mild cardiomegaly was suspected in his preoperative chest PA. After intubaton, we couldn't hear the breathing sound of left chest, and the saturation went down to 95%. There was large opaque hemithorax on emergency chest AP, and on the fiberoptic bronchoscopic examination, left main stem bronchus (LMSB) was observed
