Filter by:The primary objective is to study impact of upper airway ultrasonography in guiding anaesthetic assistant into providing accurate cricoid pressure, or both cricoid and paralaryngeal pressure in those with oesophagus deviation, achieving sonographic proven oesophageal occlusion compared to those without ultrasound guidance.
An education model with a homemade jugular venous catheterization model will be compared to the conventional training model for ultrasound-guided central jugular line catheterization. The study will include 60 residents to be divided into two groups with stratified random sampling. Training session for the control group (Group 2) will include a lecture about the subject, a demo video presentation, and practice of visualization of right jugular vein on a real human subject. Training session for the model group (Group 1) will include the same as GControl with the addition of the puncture practice on the homemade jugular venous catheterization model(HJVCM) with ultrasound guidance. Both groups will be tested with another HJVCM individually and the results of the success and fail parameters will be compared.
The objective of this trial is to compare the efficacy of three different nerve blocks as an analgesic option after total knee arthroplasty (TKA), based on muscle strength, mobilization and pain. The Adductor Canal Block has been proposed as an equally effective technique to the Femoral Nerve Block in terms of pain control after a TKA, with the benefit of preserving muscle function. We hypothesize that a block performed at the apex of the femoral triangle would best balance analgesia with quadriceps function.
This is a randomized controlled study comparing US guided vs standard procedure for PICC line placement in newborns admitted to Children's Hospital of Eastern Ontario Neonatal Intensive Care Unit who require a PICC line. Patients will be randomized using REDCap randomization module (stratified by gestational age < 28 weeks and >= 28 weeks and blocked to ensure approximate balance with each stratum) into two arms. - Arm 1: PICC line insertion procedure using anatomical landmarks and tip placement will be confirmed by X-ray (current standard); Arm 2: US guided PICC line insertion procedure and tip placement confirmation by both US and X-ray. Sample size of 33 infants per group would achieve greater than 80% power to detect a difference between groups. Primary outcome: Time to complete the standard versus the US-guided procedure. Secondary outcomes (comparison between two arms): The number of total "venipuncture" attempts needed to place a PICC line Number of tip manipulations after complete insertion Proportion of successful tip placement
While statin treatment may induce plaque regression, the effect of statin on plaque composition with varying doses is unknown. This study assessed such effects by volumetric virtual histology intravascular ultrasound (VH-IVUS). In this prospective, randomized, double-blinded pilot study, statin-naïve patients with stable angina requiring percutaneous coronary intervention (PCI) were randomized to receive 6 months of either atorvastatin 10mg or 40 mg daily. VH-IVUS was performed in all non-PCI lesions at baseline and 6 months; all analyses were performed by core laboratory.
