Filter by:Intravenous regional anesthesia is a commonly used technique in the outpatient setting for short hand and upper extremity cases, such as carpal tunnel release or trigger finger release. The technique requires a tourniquet, Esmarch bandage, an intravenous line, and lidocaine. It can be performed and learned easily. The technique is safe and easy to perform, and it provides adequate anesthesia for short cases; however, there are still some cases in which adequate anesthesia is not achieved. One of the possible reasons for failure is that the local anesthetic (lidocaine) does not properly exit the veins to reach the interstitial space (where many nerves are located) to provide the nerve block. In this study, the investigators hypothesize that after application of lidocaine to the intravenous system, application of external pressure through the skin will facilitate tissue penetration and improve the block. The only research procedure being done is a re-application of the Esmarch bandage; all other procedures are Standard of Care.
One of the most frequently performed peripheral nerve blocks (the injection of local anesthetic near nerves to block sensation/ movement to a specific part of the body) is the interscalene brachial plexus block for upper extremity surgeries. This type of block can unmask underlying respiratory issues such as shortness of breath due to a well-known and typically insignificant side effect of temporary diaphragmatic paralysis. The nerve block may be able to use saline solution to wash out the local anesthetic and potentially reverse this respiratory side effect. Specifically, the goal of this study is to determine if the injection of saline through the nerve block catheter reverses blockade of the phrenic nerve supplying the diaphragm, without affecting the ability of the nerve block to provide pain control after surgery.
This observational cohort study involves repeated cross-sectional observations in order to identify those factors associated with increased risk of PRMDs among music students. All pre-college and university-level students from several European music academies will receive an invitation to complete a web-based questionnaire survey at each of three occasions (baseline; 6-months follow-up; 12-months follow-up).
When used as perineural (PN) adjuvants to local anesthetics (LAs), dexamethasone (DX) and dexmedetomidine (DXD) have been well documented to prolong the duration of peripheral nerve blocks. These drugs have important differences in terms of cost and safety profiles. This randomized controlled trial (RCT) will compare PN DX and PN DXD for ultrasound-guided infraclavicular brachial plexus blocks (ICBs). Since analgesic and sensory duration can be influenced by factors different to block, motor block duration is the main outcome. The protocol is designed as an equivalency trial and hypothesize that both drugs result in similar durations. The equivalency margin is set at 3 hrs.
In this trial, the objective is to compare single- and double-injection ultrasound-guided costoclavicular blocks. The rationale behind this idea is that a second local anesthetic injection, inside the costoclavicular space, may compensate for the dynamic cord dispersion seen with the single-injection technique. Thus the research hypothesis is that, compared to its single-injection counterpart, a double injection costoclavicular block will result in a shorter onset time.
For this project the investigators ask, how the activation and organization of muscle synergies may be disrupted by brain lesions, and whether it is possible to modify synergy activations by means of specific therapies. Will be investigated whether there is a relationship between post-stroke cortical plasticity and changes in synergy activations due to a therapy.
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
The doses of local anesthetics can be decreased with the use of ultrasound guidance. In case of using mixture solutions the benefits and drawbacks are controversial. The plasma concentrations were not studied up to this time in this kind of settings, so investigators believe that this is the first work that shows how lidocaine change the plasma concentration of bupivacaine after axillary approach to brachial plexus employed with different dilute and mixed solutions for upper limb surgery in trauma patients.
Dexmedetomidine is an α-2 adrenoreceptor agonist and has been extensively used through intravenous infusion，in order to improved the quality of block in regional anesthesia. In this prospective, randomized study, the authors focus on the effect of dexmedetomidine mixed with ropivacaine in coracoid approach brachial plexus block.
In this prospective, randomized, double blinded study, the needle tip and needle shaft visibility of echogenic and nonechogenic needle were compared in ultrasound guided infraclavicular brachial plexus block. Sixty patients scheduled for upper extremity surgery were included in the study. Patients were randomised into two groups, group E (Echogenic) and group NE (Nonechogenic) with 30 subjects in each group. Under ultrasound guidance infraclavicular brachial plexus block was performed. In Group E, Pajunk Sonoplex echogenic needle was used and in Group NE, Stimuplex Braun nonechogenic needle was used. The subjective assessment for needle tip/shaft visibility as scored by the performer and the objective assessment from the recorded block procedure video were noted.
