Filter by:The Left interscalene block has a different effect on heart's autonomic nervous system, compared to Right interscalene block. This effect is evident on the occurrence of bradycardia and hypotension during shoulder surgery in the beach chair position
The use of ultrasound in regional anesthesia enables reduction in the local anesthetic volume. The present study aimed to determine the minimum effective volume of 0.375% bupivacaine with epinephrine for interscalene brachial plexus block for shoulder surgery. Following approval by the Research Ethics Committee, patients with a physical condition of I or II according to the American Society of Anesthesiologists, between 21 and 65 years old and subjected to elective surgery of the shoulder and interscalene brachial plexus block will be recruited. The volume of the anesthetic will be determined using a step-up/step-down method and based on the outcome of the preceding block. Positive or negative block results in a 1mL reduction or increase in volume, respectively. The success of the block is defined as the presence of motor block in two muscle groups and the absence of thermal and pain sensations in the necessary dermatomes within 30 minutes of the injection. Diaphragmatic paralysis, pulmonary function and analgesia will be quantified at 30 minutes, 4 and 6 hours. Data will undergo statistical analysis in order to determine minimum effective volume of 0.375% bupivacaine and, secondarily, the maximum volume that maintains the diaphragmatic function, evaluate diaphragm paralysis and its influence in pulmonary function.
Research study to determine the proportion of cases in which an interscalene brachial plexus nerve block produces hand and forearm anesthesia.
The Left interscalene block has a different effect on heart's autonomic nervous system, as measured with Heart Rate Variability, compared to Right interscalene block
The purpose of this study is to compare the effects and side effects of interscale block performed with Naropin 0.1% cum sufentanil or Naropin 0.1% in shoulder surgery.
The purpose of the present study was to examine the native bacteria around the shoulder and determine the efficacy of three different surgical skin-preparation solutions on the eradication of bacteria from the shoulder.
This study will test the hypothesis that the effect of dexamethasone on the analgesic duration of interscalene nerve blocks differs between ropivacaine and bupivacaine. Participants will be patients undergoing shoulder surgery with an interscalene nerve block.
Cervical paravertebral blocks (CPVBs) target the brachial plexus from a puncture site situated in the posterior aspect of the neck and represent an alternative to interscalene blocks (ISBs) for shoulder and proximal humeral surgery. Randomized controlled trials comparing CPVB and ISB have found no significant differences in success rate, onset and offset times. Because of the reliability of their cutaneous landmarks, CPVBs have become part of the investigators' standard practice. With this approach, the brachial approach can be identified either with loss of resistance to air (LOR) or nerve stimulation (NS). While some authors have used only LOR and reported good success rates, others have hypothesized that NS may increase the reliability of the block. In the proposed study, for the first time, the 2 methods will be formally compared.
The purpose of this study is to determine whether the axillary plexus block performed in lateral, head down position is effective in the perioperative analgesia in patients scheduled for elective surgery of the shoulder.
