Each patient's demographic and clinical data, including age, sex, surgical level, operation time, estimated blood loss, length of hospital stay, number of preoperative co-morbidities, and perioperative complications, were collected based on medical records.
There was no difference with respect to ASA grade, comorbidities (except cardiac comorbidities), pre- and postoperative haemoglobin levels, operation time, age or gender between the two groups.
Patients with subclinical AKI had higher albumin, lower AST level, shorter operation time, and less use of furosemide than patients with clinical AKI.
Logistic regression analysis identified the risk factors of symptoms occurring as serum sodium level variables, operation time more than or equal to 90 min, and presence of continuous drainage from bladder.
Logistic regression detected that the risk factors for being symptomatic were serum sodium level variables, operation time longer than or equal 90 min, and presence of continuous drainage from the bladder.
The risk factors for symptoms occurring were sodium level variables, operation time longer than 90 min, and presence of continuous drainage from bladder.> ROC analysis showed that the optimal cutoff value for change in absolute serum sodium concentration was 7.4 mmol/l, with an area under the ROC curve (AUC) of 0.87, a sensitivity of 0.72, and a specificity of 0.87.
The removals of Pb2+ and Zn2+ from kaolinite were evaluated using the Taguchi approach, in which the effects of five four-level parameters (operation time, electrical potential, cathode gap, concentration, and hydrostatic head) were analyzed.
If the anesthetized region was lower than the T10 sensory levels or operation time was longer than 1.5 h, 0.375% ropivacaine hydrochloride (3.0 5.0 ml) was administrated as epidural anesthesia through a catheter at L1/2 or L2/3, followed by continuous administration of 0.2% ropivacaine hydrochloride (2 5 ml/h) through the postoperative period.
Independent sample t test were used for the comparison of the parameters between each stage operation, including operation time, blood loss, number of operated levels and hospital stages.
A basic requirement for ITER equipment to meet is a high level of reliability, because ITER operation time is precious and radioactive operation leaves limited scope for repair.
In practice, it is always not so easy to suppress the short-circuit fault current by power system level operation and control in real-time, because the slower speed of system level scheduling.
