Filter by:Participants to be enrolled in this study will have been scheduled to have laparoscopic genitourinary surgery and EPAD monitoring as part of their clinical care intraoperatively. Patients scheduled for genitourinary surgery are often at risk for developing nerve injuries due to intraoperative positioning. Somatosensory evoked potential devices (SSEP) are commonly used to detect pending injury to peripheral nerves. The purpose of the present study is to use SSEP monitoring to determine the incidence and potential causes of significant changes in SSEP waveforms and correlate these changes with neurologic status of the brachial plexus after robotic surgery.
The Researchers are trying to determine if Costoclavicular brachial plexus block (CCBPB) can be successfully performed in patients with a body mass index greater than thirty.
The main objective of this study is to determine the time interval following the last treatment dose of enoxaparin at which the amount of anti-Xa level activity is reliably less than 0.2 international unit per milliliter (IU/mL) in patients presenting for elective surgery.
Medasense's Pain Monitoring Device (PMD) is a novel non-invasive, bedside stand alone, continuous monitor that is designed to provide real-time information about changes in the nociception level of patients under general anesthesia during surgical procedures. The PMD-200 System is based on real-time data acquisition and processing of physiological signals. The system displays the NOL index (a single numerical index) which is computed from recorded physiological parameters based on a proprietary algorithm.
This is an open-label feasibility study utilising direct instillation of ICG into the urethra during surgery for low rectal cancers. The trial involves a single intervention taking place during the patient's operation. Participants will be included in the study for around 2 months with time either side of the intervention to collect background data.
Surgical resection is the first choice treatment for patients with non-small-cell lung cancer. Despite of advances in surgical techniques, the long-term survival rate of postoperative patient is far from optimal. In a recent retrospective cohort study of the applicants, 588 patients after surgery for non-small-cell lung cancer were followed up for a medium of 5.2 years. The results showed that perioperative use of dexamethasone was associated with prolonged survival; perioperative use of flurbiprofen axetil was also associated with a slightly longer survival but not statistically significant. Further analysis showed that combined administration of dexamethasone and flurbiprofen axetil had additive effect in prolonging survival. We hypothesize that, for patients undergoing surgery for non-small-cell lung cancer, perioperative administration of dexamethasone and flurbiprofen axetil may improve long-term survival. However, evidences from randomized controlled trials are still lacking in this aspect.
The RIPASA score is a Clinical Prediction Rule (CPR) for the diagnosis of acute appendicitis. Since its inception in 2009, the RIPASA score has been validated in various population in healthcare institutions around the world and reported significantly higher sensitivity and specificity when compared to Alvarado score. RIPASA score ranges from 3 to 16.5 with those having a score of less than 7 having a low probability of acute appendicitis and those with a score of 7.5 having a high probability of acute appendicitis. There has been a trend in the past decade on non-operative management of early-uncomplicated acute appendicitis (EuAA) with antibiotic therapy. This antibiotic non-operative management strategy (AMS) has been reported to work in children, thus avoiding unnecessary emergency operation. In adults presenting with early-uncomplicated acute appendicitis, this management pathway is still uncertain and most randomized controlled trials (RCT) and meta-analysis have not been able to show significant benefit of AMS over surgery management strategy (SMS), partly due to variable treatment efficacy, high recurrence rate within a year and a lack of agreement of whom would constitute a group of EuAA. The working hypothesis of this study is that RIPASA score as a Clinical Prediction Rule, can determine a group of patients with a diagnosis of EuAA, based on the range of scores (RIPASA score 7.5 - 11.5), who will benefit from an AMS rather than SMS, leading to improve patients' outcomes through a significant reduction in negative appendicectomy rate, shorter length of hospital stay, reduce post-operative complications and changing physician behavior in managing this group of patients to an AMS rather than SMS and ultimately financial cost savings. The primary specific aim of this study is to compare AMS with SMS in patients with EuAA in a prospective non-inferiority RCT. Secondary specific aims are to determine the range of RIPASA score that can define a group of patients with EuAA, step 3 validation of RIPASA score as a valid CPR and improve patient outcomes in terms of reducing unnecessary negative appendicectomy rate, hospital stay and complications arising from such surgery, and ultimately financial cost savings.
This is an open-label, non-comparative phase II clinical trial to assess efficacy and safety of tongue conservation treatment with sequential induction chemotherapy, tongue conservation surgery and postoperative concurrent chemoradiotherapy (CCRT) in patients with advanced oral tongue cancer.
To compare the effect of lumbar spinal manipulation, physical therapy and surgical management in the treatment of lumbar spinal stenosis.
This study evaluates the difference in results between eyes that have been treated wavefront optimized laser vision correction (either LASIK or Photorefractive Keratectomy) compared to eyes treated with topography-guided laser vision correction (either LASIK or Photorefractive Keratectomy). Each participant will receive wavefront optimized correction in one eye and topography-guided correction in the other.
