Filter by:The investigators are conducting a prospective, randomized trial to investigate whether patients randomized to receive an augmented bladder neck reconstruction (aBNR) at the time of robotic-assisted laparoscopic prostatectomy experience improved urinary function post-operatively compared to patients who undergo prostatectomy with a standard BNR. An aBNR here consists of the autologous medial umbilical ligament sling as well as a bladder neck intussusception stitch. The standard BNR group will receive the intussusception stitch only.
This randomized controlled trial will study the effects of peanut protein supplementation on changes in muscle size and quality in patients undergoing total knee arthroplasty.
Prospective, open-label clinical trial to evaluate the efficacy and safety of andexanet alfa patients who require urgent surgery that have been anticoagulated with the FXa (activated factor X) inhibitors.
To determine whether partially filling the bladder after outpatient gynaecological laparoscopy expedites time to first void and discharge. Methods: A single site, single-blinded, randomized control trial in which eligible patients undergo partial retrograde bladder filling immediately post-operatively compared to bladder drainage and foley catheter removal. Primary outcome is time to first void, secondary outcomes include time to discharge, post-operative complications and patient satisfaction.
To investigate if signal processing can detect subtle changes in speech production clinically relevant to oropharynx anatomy that may provide an objective measure in the assessment of the presumed difficulty of intubation.
Cerebral blood flow is tightly regulated to ensure constant cerebral perfusion independently from systemic blood pressure fluctuations. This mechanism is termed cerebrovascular autoregulation and preserves adequate cerebral perfusion in a range between 50 and 150 mmHg of cerebral perfusion pressure. Upper and lower autoregulatory limits may vary individually. Beyond the autoregulatory range the protective autoregulatory response is lost, facilitating cerebral ischemia or hyperemia. The cerebrovascular response may be altered during general anesthesia, through direct effects of anesthetic agents on the vascular tone, changes of arterial partial pressure of carbon dioxide or the administration of vasoactive substances. The association of perioperative impairment of cerebral autoregulation and postoperative cognitive function has been discussed controversially.
A prospective multicenter observational cost-utility study following older or high-risk patients with colorectal cancer with and without prehabilitation before surgery.
In this observational study, all enrolled patients having a thoracic surgical procedure requiring lung isolation will have a bispectral index (BIS) monitor placed at time of induction. BIS monitors are used to assist in determining depth of anesthesia. This study will evaluate changes in BIS before, during and after lung isolation.
Does the introduction of a preparatory virtual reality (VR) program that is used in the home environment, have an effect on the anxiety level of children immediately before surgery, prior to administration of preoperative sedatives?
Clinicians need to measure energy expenditure (EE) by indirect calorimetry (IC) to optimize nutritional support for a better clinical outcome, especially in patients with chronic conditions or with high risk of under- and over- feeding. However, IC is rarely used in clinical routine because the devices currently on the market are of tedious use, imprecise and expensive. An easy-to-use, accurate and inexpensive IC device (Q-NRG® CE marking n°MED 9811) has been developed to meet specifications made by and for clinicians. The ease of use of this new IC device has been first evaluated in mechanical ventilation mode. This second phase aims at evaluating the ease of use, the stability and the feasibility of the measurements with this new IC device in canopy and face mask modes for spontaneously breathing adult patients.
