Cholecystolithiasis and Thyroid Nodule Clinical Trial
Official title:
Effect of Different Infusion Volume on Perioperative Bladder and Blood Volume in Patients Undergoing Daytime Surgery.
The objective of the trial was to explore the effect of different infusion volume on perioperative bladder and blood volume in patients undergoing daytime surgery assisted by bladder and vascular ultrasound and transthoracic echocardiography.
The objective of the trial was to evaluate the effects of different infusion volume of Ringer's solution acetate (2 ml/kg,8ml/kg, 16ml/kg) on bladder volume, hemodynamics,transthoracic echocardiography and vascular ultrasound including the inferior vena cava(IVC) and the right subclavian vein(SCV) diameter and the IVC and SCV collapsibility index in patients undergoing daytime surgery through a randomized controlled clinical study, so as to provide better guidance for clinical transfusion avoiding bladder catheterization . The patients in this trial were visited before induction and discharge from the postanaesthesia .We also collected the first time and times of micturition and whether the patients have the dysuria. ;
