Filter by:Interscalene brachial plexus block (ISB) is considered the standard nerve block for shoulder surgery . It provides superior analgesia and reduced opioid-related adverse effects . However, it is challenging to perform and may be associated with a high incidence of ipsilateral hemidiaphragmatic paresis, resulting from a phrenic nerve block . Although that complication could be decreased with modified local anesthetic dosing and ultrasound-guided needle placement , its incidence significantly impair the mechanics of breathing leading to postoperative morbidity, making that block undesirable in patients with impaired pulmonary functions . This clinical problem has recently received considerable attention, with several calls to seek alternatives to interscalene block in shoulder arthroscopy [18]. So, the need for a safer ISB alternative has prompted researchers to examine several options, including but not limited to the suprascapular [19] and pericapsular nerve blocks . Pericapsular nerve block has been studied extensively in hip surgeries , and some physicians suggested that it can be safely applied for analgesia and can be part of surgical anesthesia in shoulder arthroscopic surgery. It induces blockade of the articular branches that innervate the glenohumeral joint . The block of this area does not cause motor block or pulmonary complications, nor result in muscle laxity, blocking only the shoulder and the upper third of the humerus . The cervical plexus is formed by the ventral rami of C1-C4 cervical roots. It can be blocked at the superficial, intermediate and at the deep level [24]. The superficial cervical plexus block results in anesthesia of skin over the anterolateral neck, skin overlying the clavicle and the sternoclavicular joint, anterior and retroauricular areas . Although that block is effective in pain management after surgeries involving the distal clavicle, it has been poorly described in shoulder arthroscopy.
The aim of this study is to compare the effectiveness of interscalene brachial plexus block alone versus interscalene brachial plexus block +Erector spinae plane block in anesthesia for shoulder arthroscopy.
The aim of this study is to compare the effectiveness of ESPB versus ISB in anesthesia for shoulder arthroscopy
To compare ISB vs anterior and posterior approaches of suprascapular block in terms of lung function and analgesia
Interscalene brachial plexus block is the gold standard for perioperative pain management in shoulder surgery. However, this technique would have side effects and potential serious complications. The aim of this study is to compare between the combination of ultrasound guided suprascapular and supraclavicular nerve blocks versus ultrasound guided interscalene brachial plexus block for post operative analgesia after shoulder instability surgery with latarjet procedure.
The main aim of the study is to investigate the proven effect of dexamethsone on the duration of the interscalene block. The investigators try to define optimal dose and volume for ropivacaine, when used together with dexamethsone. The current literature uses often very high volumes of ropivacain when used together with dexamethasone. The investigators try to research the effect of using dexamethsone together with low volume, high concentration ropivacaine for interscalene blockade. The investigators' hypothesis is that dexamethasone has an positive effect on the pain free after used together with ropivacaine at the scalene block.
The objective of this randomized controlled trial is to compare the analgesic efficacy and the safety profile between two techniques of injection for the interscalene block. The interscalene block consists of injecting local anesthetic around the cervical roots of the brachial plexus and allows analgesia after shoulder surgery. Stated differently, the dual objective of that study is: 1. to confirm that an injection at a distance of 4 mm away from the lateral sheath of the plexus (distal injection) provides similar analgesia as a classical injection within the plexus (subfascial injection); 2. to demonstrate that a distant extrafascial injection produces less respiratory complications than a subfascial injection, defined as hemidiaphragmatic paresis.
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 purpose of this study is to determine if a decrease in the standard volume of local anesthetic used to numb your shoulder area before shoulder arthroscopy will provide adequate anesthesia for the procedure and decrease the amount of time until you are ready for discharge from the hospital.
