There are about 348 clinical studies being (or have been) conducted in Belarus. 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.
About 15 million spinal anesthesia procedures are performed worldwide each year. In the daily practice of the anesthesiologist for intrathecal use there are various local anesthetics such as bupivacaine, hyperbaric solution of bupivacaine, ropivacaine and levobupivacaine. From 1946 to 2017, only 16 studies comparing the clinical efficacy of isobaric and hyperbaric bupivacaine in nonpregnant patients have been conducted according to various databases. The small sample size and high heterogeneity of these results suggest that all results should be treated with caution. And, there is no conclusive evidence in favor of isobaric or hyperbaric bupivacaine regarding efficacy or side effects in the general surgical population. The literature describes such advantages of levobupivacaine as less cardiotoxicity, longer period of analgesia, more pronounced activity against sensory fibers than against motor fibers. In some studies it has been shown that levobupivacaine is equal to isobaric bupivacaine in efficacy. The efficacy of hyperbaric levobupivacaine equivalent to hyperbaric bupivacaine when administered intrathecally has also been shown on volunteers. However, in the literature there are different data on clinical efficacy of levobupivakin in comparison with ropivacaine and levobupivacaine. So during operations on extremities out of 20 patients surgical anesthesia developed in 18 patients. Fattorini F. et al. D in their study stated the same effectiveness of bupivacaine and levobupivacaine, but when using levobupivacaine in one patient general anesthesia was used due to insufficient spinal anesthesia. Other studies also reported similar efficacy of the two drugs, but surgical satisfaction with intraoperative anesthesia was 92.9% for bupivacaine and 83.9% for levobupivacaine for knee arthoroscopy. In their study, P Gautier et al. noted significantly lower efficacy of levobupivacaine in caesarean section compared to bupivacaine and ropivacaine for intrathecal use: 80% vs. 90% and 87%, respectively. According to Heng Sia et al. there is no clear evidence of the advantage of hyperbaric bupivacaine over isobaric bupivacaine for spinal anesthesia for cesarean section. The authors also noted that adequate randomized clinical trials with clear definitions, criteria and methodology for evaluating the transition to general anesthesia, requirements for additional analgesia, nausea, vomiting and sensory testing are needed. There is no clear practical guide to help anesthesiologists make informed decisions about the use of some form of intrathecal bupivacaine in non-cesarean surgery. Carefully designed, adequately conducted studies can provide further results that will contribute to sound clinical decision making. Given the above, the aim of the study is to compare the effectiveness of spinal anesthesia (SA) performed with 0.5% isobaric bupivacaine solution, 0.5% levobupivacaine solution and 0.5% hyperbaric bupivacaine solution in equivalent volumes in lower limb surgeries.
The purpose of the study is to enable participants with pulmonary hypertension (PH) currently treated with study intervention(s) in a clinical study (parent studies [NCT03422328, NCT03904693 and NCT04565990]), to continue to benefit from the intervention after closure of the parent study in case they have no alternative means of access to the study intervention. This study will allow assessment of the long-term safety of each study intervention.

This study will be evaluate the clinical efficacy of using graduated compression hosiery for venospecific symptoms, leg edema, and quality of life (QoL) in pregnant women with varicose veins (VV's).
Treatment of metastatic tumors of the urogenital area with cytokine-induced killer cells
In modern anesthesiology, peripheral nerve blocks are performed using ultrasound control and electrical stimulation of peripheral nerves (PEN), or only ultrasound control or only PEN. The most effective methods are with the use of ultrasound control. Until now, the effectiveness of the sciatic nerve blockade by the subgluteal approach, performed only under ultrasound control without ESP, in comparison with the blockade of the sciatic nerve performed under ultrasound control with ESP, has not been established. Research hypothesis: the blockade of the sciatic nerve by the subgluteal approach performed only under ultrasound control has the same effectiveness as the blockade performed under the ultrasound control with EPN.
Phase 0/1 local application of the monoclonal antibody (Mab) sB24M in patients with purulent pyoderma (chronic ulcerative pyoderma) by injection into the affected areas. Monoclonal antibody (Mab) sB24 negatively regulates immune-inflammatory processes through CD47 / TNF-α Axis promotes epithelialization of damaged tissue.
This is a phase 2, multicenter, randomized, double-blind, placebo-controlled, parallel-group study in patients with moderate to severe active ulcerative colitis.
This study evaluates either KRT-232 or TL-895 in treatment naïve patients with myelofibrosis (MF) The study will be conducted in 2 stages. Stage 1 will evaluate safety, tolerability, and efficacy of either KRT-232 (Arm 1) or TL-895 (Arm 2) in treatment naïve patients. Stage 2 will expand enrollment in Arm 1 and/or Arm 2 if expansion criteria is met.
