About this study

The investigators will compare the BP block efficacy (for surgical anaesthesia) with the USG single-penetration multiple-injection-technique at the SCL, LIC and AX level for upper-extremity surgery (elbow, forearm, wrist, hand). The investigators want to investigate whether the single-penetration multiple-injection-technique would provide for safe surgical anaesthesia with lower volumes of local anaesthetics than has previously been described in a comparative study at the three different levels.

120 patients will prospectively be randomized to an USG BP block administered as a single-penetration multiple-injection-technique at one of three different levels: (1) SCL (2) LIC (3) AX. Ropivacaine 0.75% (20 mL) will be used for all blocks prior to surgery.

Treatment and study plan

Ropivacaine

Drug

20 ml in total of 0,75% Ropivacaine is administered to each patient in all three arms.

Other names: Naropin

Primary outcomes

  1. Blockade performance time (seconds)

    Time frame: Time (seconds) from the time the ultrasound transducer is placed on the skin and until the needle is taken out of the body.

Secondary outcomes

  1. Onset time of blockade (minutes)

    Time frame: Time from block completion to complete sensory and motor block is accomplished.

  2. Number of needle passes

    Time frame: Number of times the direction of the needle changes while performing the block

  3. Patient reported pain related to needle passes (Scale 0-2)

    Time frame: Pain related to block performance reported by the patient right after block completion

    0= no pain

    • middle
    • sever pain

  4. Duration of time of block postoperatively (hours)

    Time frame: Patient reported the time off ending sensory and motory block
