There are about 9311 clinical studies being (or have been) conducted in Korea, Republic of. 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.
Adequate preoperative fasting is critical in preventing pulmonary aspiration of gastric content. Ultrasonography is considering as a useful test assessing the volume of gastric contents, but the emptying time of a rice-based meal (Asian foods) in healthy populations was not clear. The objective of this study was to investigate the minimum fasting time required for adequate gastric emptying after the ingestion of a rice-based meal.
This study objectives is to evaluate the efficacy of YD312 to improve visual acuity in patients with diabetic macular edema (DME) compared to placebo and determine optimal dose of phase 2b study.
This is prospective cohort study of patients classified by the premedication history of beta-blocker. We aim to evaluate the hemodynamic effect of beta blocker through Swan-Ganz catheter monitoring and arterial pressure waveform analysis during surgery. We also plan to observe the long-term effects of beta blocker on acute renal failure, allograft failure and mortality.
Efficacy and Safety of Acupuncture Treatment as an Adjunctive Therapy After Knee Replacement
The purpose of this study is to evaluate the Pharmacokinetic Interaction Between AD-2071 and AD-2072 in healthy male volunteers.
The objective of this study is to compare the efficacy and safety of dexmedetomidine with other sedatives in sedation during endoscopy by analyzing the most recently published interventional trials and observational studies.
In this study, changes in the motor network were investigated to delineate the roles of brain areas and connectivity on the recovery of brain functions by using longitudinal magnetic resonance imaging data.
The purpose of this study was to investigate the incidence of hypotension after spinal anesthesia in patients undergoing cesarean section as predicted by preoperative carotid artery corrected flow time measured by Doppler ultrasound. Before entering the operation room, Two inspectors perform two measurements of carotid artery corrected blood flow time respectively, and an average of the four measurements is calculated and analyzed. At this time, the patient's posture is supine, and the head is turned about 30 degrees to the left. Corrected blood flow time (FTc) is measured using carotid ultrasound as previously described by Blehar and colleagues. Corrected blood flow time is calculated by Bazett's formular and Wodey's formular by evaluating a single cycle after several successive cycles have reached a stable and acceptable quality level. The occurrence of hypotension is recorded from the spinal anesthetic injection until the fetus is delivered. The definition of hypotension after spinal anesthesia is that the systolic blood pressure drops to 80 mmHg, less than 75% of the baseline value, or even if it does not meet the former criteria, symptoms that are consistent with hypotension (dizziness, dizziness, dyspnea, nausea or vomiting).
Transnasal Humidified Rapid-Insufflation Ventilatory Exchange (THRIVE) was revealed to prolong apneic time with a slow increase in carbon dioxide; thus, has been used for preoxygenation in patients with difficult airways or requiring rapid sequence induction in general anesthesia. However, in patients undergoing hypopharyngeal and laryngo-tracheal surgery, THRIVE during operation can be advantageous by allowing tubeless surgical field with sufficient oxygenation. Therefore, the investigators conducted this study to evaluate the efficacy of THRIVE on prolonged apneic time with enhanced surgical conditions in patients with laryngeal microsurgery.
The purpose of this study is to evaluate the Pharmacokinetics and safety/tolerability between Fimasartan/Amlodipine/Hydrochlorothiazide and co administration of Fimasartan/Amlodipine and Hydrochlorothiazide in Healthy volunteers.
