NCT03713268
The overall five-year goals of the project are to develop novel technology to provide actionable new information through provision of live volumetric imaging during surgery, improving surgical practice and outcomes. The investigators believe this technology will enable novel ophthalmic and other microsurgeries not possible due to current limitations in surgical visualization.
NCT07208552
The study population consists of term primigravida women undergoing induction of labor at a tertiary care referral center in Assiut, Egypt.
NCT05513378
OBJECTIVES The primary objective is to compare if the addition of a needle guide can reduce the number of central venous catheter (CVC) insertions with \>1 skin puncture in ultrasound-guided catheterization of the subclavian vein using the long-axis approach with an in-plane needling technique. Secondary objectives include if this addition 1) decreases the frequency of mechanical complications (defined as bleeding, arterial puncture, arterial catheterization, nerve injury, pneumothorax), 2) increases the time when the needle is visible, 3) decreases the time until successful vessel punction, 4) decreases the number of needle redirections during the insertion, and 5) a comparison between the two groups regarding number of failed catheterizations. DESIGN This is a prospective, randomised, controlled, parallel intervention study. Patients will be enrolled at Skåne University Hospital in Lund, Sweden. The trial is investigator-initiated and non-commercial. POPULATION AND INTERVENTION Adults (18 years of age or older) in need of a subclavian CVC for any reason and able to give written informed consent will be included in the study provided no exclusion criteria is fulfilled. OUTCOMES Primary outcome will be number of CVC insertions with \>1 skin puncture. Secondary outcomes include comparison between the two groups regarding 1) the frequency of mechanical complications, 2) proportion of the insertion-time when the needle is visible on the ultrasound (US) screen, 3) time to successful vessel punction, 4) the number of needle redirections during the insertion, 5) number of failed catheterisations, 6) Feasibility of the needle guide evaluated with a questionair to the operators at the end of the study.
