NCT ID: NCT06375538 Recruiting - Clinical trials for High-flow Nasal Cannula

Ultrasound Evaluations of Diaphragm and Intercostal Muscle to Predict the Failure of High-Flow Nasal Cannula Therapy

Start date: October 21, 2022
Phase:
Study type: Observational

The study aims to predict the failure of High-flow Nasal Cannula oxygenation therapy by ultrasound evaluation of diaphragm and intercostal muscle contraction during the first 24 hours.

NCT ID: NCT04786626 Not yet recruiting - Clinical trials for Ultrasound Evaluation

Ultrasound Evaluation of Uterine Healing After Vaginal Repair of Cesarean Scar Defect (CSD)

CSD
Start date: March 20, 2021
Phase:
Study type: Observational

Cesarean scar defect is one of the complications after cesarean section (CSD). CSD may be further caused many long term complications, such as abnormal uterine bleeding, infertility, uterine scar pregnancy and uterine rupture. Vaginal repair due to CSDs is a minimally invasive and effective method that maintains fertility. The main concern linked to surgery is the quality of healing of the myometrial incision. However, no diagnostic method has yet been widely accepted to assess the healing process. Thus, the authors investigated uterine healing after vaginal repair with two-dimensional (2D) power Doppler ultrasound (PDU) in this study.

NCT ID: NCT04529837 Completed - Induction of Labor Clinical Trials

Ultrasound Assessment of DILAPAN-S

Start date: October 1, 2020
Phase:
Study type: Observational

The goal of this observational prospective study is to assess the change in Dilapan-S rod diameters using transvaginal ultrasound over a period of 12 hours in term women undergoing induction of labor.

NCT ID: NCT04208438 Completed - Clinical trials for Ultrasound Evaluation

Non-Invasive Jugular Venous Blood Volume Assessment (BVI)

Start date: June 5, 2019
Phase:
Study type: Observational

The purpose of this study is to evaluate the ability of the Mespere Blood Volume Index (BVI) device to calculate the blood volume in the jugular veins by comparing the measurements from the device to volumetric measurements obtained with ultrasound.
