NCT04000100

Brief Summary

Patients were randomly allocated into Two equal study groups each contain (40) patients : Patients in Group A received supraclavicular block using 25mL of 0. 5% bupivacaine and 1 mL normal saline and patients in Group B received 25 mL 0. 5% bupivacaine and 1 mL neostigmine (0.5 mg). The investigators found that neostigmine when used as an adjuvant to bupivacaine in ultrasound guided supraclavicular brachial plexus block has advantage over bupivacaine alone especially in the quality of sensory block and provide safe and effective post-operative analgesia in patients undergoing forearm surgeries

Outcome Measures

Primary Outcomes (4)

  • The onset of sensory blockade

    Onset time for sensory block was defined as the time interval between the end of local anesthetic administration untill complete sensory block by minutes

    Every 2 minutes for 30 minutes

  • The onset of motor blockade

    Onset time for motor block was defined as the time interval between the end of local anesthetic administration until complete motor block by minutes

    Every 2 minutes for 30 minutes

  • Duration of sensory blockade

    Duration of sensory block was defined as the time interval between the complete sensory block and complete resolution of anesthesia on all the nerves by hours

    Every 1 hour for 24 hours

  • Duration of motor blockade

    the time interval from complete motor block to complete recovery of motor function of hand and forearm by hours

    Every 1 hour for 24 hours

Secondary Outcomes (2)

  • Duration of analgesia (first request for analgesic)

    Every 30 minutes for 4 hours then every 2 hours for 24 hours

  • Visual analogue pain score

    2,4,6,8,12,16,20 and 24 hours postoperative

Study Arms (2)

Control group

PLACEBO COMPARATOR

This group received supraclavicular block using 25mL of 0. 5% bupivacaine and 1 mL normal saline

Procedure: ultrasound- guided supraclavicular brachial plexus block

Neostigmine group

ACTIVE COMPARATOR

This group received 25 mL 0. 5% bupivacaine and 1 mL neostigmine (0.5 mg)

Procedure: ultrasound- guided supraclavicular brachial plexus block

Interventions

Patient lie down supine with head turned 45 degrees to the contralateral side and ipsilateral arm adducted gently by the assistant and the shoulder kept down with flexed elbow. After sterile preparation of the skin and the ultrasound probe (12 MHz probe) were used, the brachial plexus was visualized by placing the transducer in the sagittal plane in the supraclavicular fossa behind the middle-third of the clavicle. Two distinct appearances of the brachial plexus was seen at the supraclavicular region, it either appeared as 3 hypoechoic circles with hyperechoic outer rings or as a grape like cluster of 5 to 6 hypoechoic circles, located lateral and superior to the subclavian artery between the anterior and middle scalene muscles at the lower cervical region figure
