NCT06428461
This study aimed to evaluate the anesthesia adequacy, side effects, and complication rates, as well as the postoperative pain relief effectiveness of supraclavicular brachial plexus blocks administered at different volumes under ultrasound guidance. Additionally, the investigators utilized ultrasound to measure optic nerve sheath diameters and investigated their relationship with intracranial pressure across varying block volumes.

Introduction: Current evidence supports the existence of preoperative anxiety and its undesirable effects during surgery and in the postoperative period. Despite numerous studies that have evaluated the effectiveness of different non-pharmacological interventions in reducing preoperative anxiety, we have not found any that use an image catalog. Objective: To evaluate the effect of an intervention based on the visualization of an image catalog on the improvement of perceived anxiety in patients undergoing upper limb orthopedic surgery. Methodology: A prospective, randomized, controlled, parallel-group clinical trial with a 1:1 ratio will be conducted. The study will include 167 patients scheduled for upper limb surgery who are over 18 years old, without blindness or decreased visual acuity that cannot be corrected with appropriate lenses. The subjects will be invited to explain the study's objective and perform baseline assessments. On the day of the surgical intervention, both groups will receive standard care, but those in the intervention group will also visualize a catalog of 8 images, 25 minutes before entering the operating room. In addition, 30 and 10 minutes before the intervention begins, all patients included in the study will have vital signs taken, be administered Spielberger's anxiety scale, visual analog scale for anxiety, and cortisol levels in saliva will be determined as measures of preoperative anxiety. The final evaluation will measure whether this intervention results in decreased anxiety, postoperative complications resulting from anxiety, and length of hospital stay.

Among paediatrics aging 3:12 who are going to have upper limb surgery,does adding clonidine to bupivacaine improve brachial plexus block outcome in comparison with magnesium sulfate with bupivacaine?
NCT02657291
Patients for upper limb surgeries who are candidates for infraclavicular block will be screened. Two techniques of infraclavicular block will be compared. Measured outcomes are performance times, block onset times, patient satisfaction, quality of block, and requirement for supplementary analgesia.
NCT03528018
Rehabilitation options for stroke survivors who present severe hemiparesis in chronic stages are limited and may end in compensation techniques that involve the use of the less affected arm to achieve some degree of functional independence. Transcranial direct current stimulation (tDCS) is a non-invasive technique that has been used after stroke to promote excitability of the surviving neural architecture in order to support functional recovery. Interestingly, cortical excitability has been reported to increase when tDCS is combined with virtual reality. This synergetic effect could explain the promising results achieved by preliminary experimental interventions that combined both approaches on upper limb rehabilitation after stroke. The objective of this study is to explore the use of these interventions in subjects with severe hemiparesis and to determine its efficacy in comparison to conventional physical therapy
