There are about 1320 clinical studies being (or have been) conducted in Saudi Arabia. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Patients admitted to the intensive care unit are at high risk of developing clots in the veins of the lower extremities. The objective of this study is to examine whether the use of a device that provides intermittent compression to the legs in addition to the use of low-dose blood thinners, provides an additional protection when compared to the use of blood thinners alone. Patients who are admitted to the intensive care unit are receiving low-dose blood thinners to prevent clots are candidates for this study. Patients who are enrolled will continue to receive blood thinners but some will additionally receive the leg compression. The additional use of leg compression may provide protection from clots. The main side effect is possible skin abrasions but this is usually mild. The study is sponsored by King Abdullah International Medical Research Center(KAIMRC) and King Abdulaziz City for Science and Technology(KACST) and will be conducted in several hospitals in Saudi Arabia, Canada, Australia, Brazil and possibly other countries. The study started July 2014 and is to continue for 4 years.
Research Problem: Shock wave lithotripsy (SWL) dramatically changed the management of renal and ureteral calculus disease. In vitro studies suggest that progressive increase in lithotripter energy output voltage could produce the best overall stone comminution in comparison with constant or deescalating energy output. However, it is possible that the beneficial impact of slow rate SWL on comminution of stones and stone free rates has masked any marginal benefits for energy output escalation. The Escalating SW method adds the benefit of less renal tissue injury. Research Significance:The present study will signifies and evaluates the stone free rates of three groups of patients with renal stones treated with different SWL energy outputs (Escalating, Constant and Reduction energy output). Research Objectives: The aim of this research project is to study the effect of dose adjustment strategies on success rate of Shock Wave Lithotripsy in the clinical setting and to optimize the conditions for successful Shock Wave Lithotripsy. Research Methodology: This clinical trial will be conducted at a tertiary care university hospital. 150 patients referred to the Shock wave lithotripsy unit will be evaluated for eligibility to be randomized into three groups (Dose Escalation, Dose reduction and constant dose). Parameter of the three groups will be compared to detect the treatment difference.
The study was designed to determine whether maternal xylitol consumption through regular chewing of xylitol gums can affect the salivary mutans streptococci (MS), dental caries, and dental plaque levels of their children.
The development of target effect-site controlled concentrations (TCI) of remifentanil have gained increasing acceptance during cardiac surgery as regarding the resulting of hemodynamic stability and early extubation. The use of low-dose opioid technique has been progressively used nowadays because of its ceiling effect to attenuate cardiovascular responses to noxious stimuli. We hypothesize that the use of low target remifentanil effect site concentrations may provide comparable shorter times to tracheal extubation and hemodynamic stability to the use of high remifentanil Ce during target-controlled propofol anesthesia for cardiac surgery.
Selective lobar blockade (SLB) is a specific technique that allows collapse of the operated lobe during thoracic surgery while the other lobes are ventilated. It is associated with the improvement of arterial oxygenation during one lung ventilation (OLV) for thoracic with providing adequate surgical access. The purpose of this study is to compare the efficacy of three bronchial blockers, namely an Arndt® wire-guided endobronchial blocker, a Cohen Flexi-tip endobronchial blocker or a Fuji Uni-blocker, for achieving selective lobar collapse.
The use of dexmedetomidine as an adjunct to bupivacaine in transversus abdominis plane block will reduce the cumulative morphine consumption after laparoscopic cholecystectomy.
Although the administration of muscle relaxation is essential standard of care for thoracic procedures, it could cause long-reversal times and postoperative residual curarization (PORC) increasing length of post-anesthesia care unit (PACU) stay and hospital costs. Sugammadex offers new perspectives to reduce the incidence of PORC. Unfortunately it is not available in many countries because of its significantly high cost. We hypothesized that the use of target-controlled remifentanil infusion (TCI) with the non-muscle relaxant (NMR) would be associated with comparable surgical conditions and reduced total costs compared with the use of neuromuscular blockers during thoracotomy. After ethical approval, 66 patients scheduled for elective thoracotomy under sevoflurane anesthesia with TCI remifentanil will be included in this prospective, randomized, single-blind, controlled study. Patients will be randomly assigned to receive cisatracurium or saline (n = 33 for each group) throughout the procedure. Laryngoscopy and intubating conditions, intraoperative modified thoracic surgery rating scale (Table below), incidence of light anesthesia, and use of vasopressors and anesthetics, clinical recovery, incidence of PORC, PACU and hospital stays, and total costs will be recorded.
The use of wire-guided Arndt® endobronchial blocker does not gain widespread acceptance during video-assisted thoracoscopy (VATS) because it takes longer time to collapse the operative lung especially in patients with chronic obstructive lung disease (COPD). The use of a disconnection technique for deflation of Arndt® blocker had a comparable degree of lung collapse with the use of double-lumen tubes. However, it carries a risk of blood or infected secretions contaminating the dependent lung. We hypothesise that the use bronchial suction of through a barrel part of a 1-mL insulin syringe attached to the suction port of the bronchial blocker would be associated with comparable time to optimum lung collapse with the disconnection technique. After ethical approval, 58 patients with spontaneous pneumothorax scheduled for elective VATS using Arndt blocker® for lung separation will be included in this prospective, randomized, double-blind study. Patients will be randomly assigned to deflate the blocker with either disconnecting the endotracheal tube from the ventilator for 60 s. prior to inflation of the bronchial blocker allowing both lungs to collapse, or attaching -20 cm H2O of suction to the suction port of the blocker through the barrel part of a 1-mL insulin syringe (n = 29 for each group).
The purpose of this study is to explore the efficacy and safety of Atorvastatin in combination with multimodality therapy of concurrent radiotherapy plus temozolomide followed by adjuvant temozolomide in patients with newly diagnosed glioblastoma multiforme (GBM).The anticipated time on study treatment is until disease progression, and the target sample size is 32 individuals.
• Introduction: Effective pain control is critical in pediatric dentistry. The effectiveness of pain control in children can be influenced by child characteristics . Objectives: The Purpose of the study is to compare the pain perception and the effectiveness of anesthesia between the computer-controlled local anesthetic delivery system (CCLAD) and the traditional inferior alveolar nerve block (IANB) in pulptomies of the mandibular second primary molars. Materials and Methodology: The study sample includes 90 healthy children who are selected randomly from the R4 electronic filing system in King Abdulaziz University Hospital (KAUH) with age range from 5-9 years. The child is required local anesthesia for pulpotomies in the mandibular second molars. The sample will be divided randomly to one of these 3 groups: group A is composed of 30 patients who will be anesthetized by the traditional IANB. Group B includes 30 patients will be anesthetized by the IANB using CCLAD. While, the remaining 30 patients will be assigned in group C and will be anesthetized by periodontal ligament injection anesthesia using the CCLAD. The pain perception levels after the injection is assessed by a Wing-Baker faces pain scale. Effectiveness of the anesthesia during each step in pulpotomy is measured using Sounds, eyes and motor (SEM) scale. After the treatment by 24 hours parents will be contacted by the telephone to ask about the presence of postoperative pain or lip biting. Statistical analysis is carried out using SPSS version 16.00.
