Brief Summary:
The aim of this study is to evaluate the role of verapamil when added to bupivacaine in ultrasound-giuded supraclavicular Brachial plexus block regarding the duration of action of the block, onset of action and the need of rescue analgesia.
Detailed Description:
Preoperative Period All patients will clinically be assessed and routine preoperative investigations will be done: Complete blood picture, Coagulation profile, liver function tests, kidney function tests, fasting blood sugar and ECG. The initial vital data will be measured after applying the standard monitoring including pulse oximetry, non-invasive blood pressure and ECG. All patients will be admitted after fasting for 6 hours.
Intraoperative Period On arrival of the patients to the operative room, electrocardiography, non-invasive blood pressure, and pulse oximetry will be applied. Baseline parameters such as systolic blood pressure (SBP), diastolic blood pressure (DBP), mean blood pressure (MBP), heart rate (HR), and oxygen saturation (SpO2) will be recorded. Intravenous (IV) line will be inserted and IV lactated Ringer will be started.
The block will be performed using a portable ultrasound system (sonosite M-turbo USA) with linear high-frequency transducer (12HZ) to get the sonographic anatomy of brachial plexus in the transverse and longitudinal planes.
Under aseptic conditions, the ultrasound probe will be situated parallel to the clavicle in the supraclavicular area to show the plexus as a "bunch of grapes" or as having a "honeycomb" appearance. The block will be done with a short beveled echogenic needle 5 cm, 22 G for optimal control and visibility. The predetermined volume of 22 ml will be injected around the brachial plexus after negative aspiration to avoid inadvertent intravascular injection keeping in mind adequate block of lower trunk. Distension of brachial plexus sheath will be regarded as an indication of successful block "Donut sign". A massage for 5 min will be applied to aid an equal volume distribution.
