Effect of Different Infusion Volume on Perioperative Bladder and Blood Volume in Patients Undergoing Daytime Surgery.

May 12, 2022 updated by: Wen-fei Tan, China Medical University, China
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.

Study Overview

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.
