Primary Outcome Measures:
  • 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 Outcome Measures:
  • Onset time of blockade (minutes) [ Time Frame: Time from block completion to complete sensory and motor block is accomplished. ]
  • Number of needle passes [ Time Frame: Number of times the direction of the needle changes while performing the block ]
  • 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

    1. middle
    2. sever pain

  • Duration of time of block postoperatively (hours) [ Time Frame: Patient reported the time off ending sensory and motory block ]

Estimated Enrollment: 120
Study Start Date: April 2013
Study Completion Date: June 2015
Primary Completion Date: October 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: USG Supraclavicular block
20 ml of ropivacaine 0,75% is administered to brachial plexus at supraclavicular level.
Drug: Ropivacaine
20 ml in total of 0,75% Ropivacaine is administered to each patient in all three arms.
Other Name: Naropin
Active Comparator: Lateral infraclavicular block
20 ml of ropivacaine 0,75 % is administered to brachialis plexus at lateral infraclavicular level
Drug: Ropivacaine
20 ml in total of 0,75% Ropivacaine is administered to each patient in all three arms.
Other Name: Naropin
Active Comparator: USG Axillaris block
20 ml of ropivacaine 0,75% is administered to plexus brachialis at axillaris level
Drug: Ropivacaine
20 ml in total of 0,75% Ropivacaine is administered to each patient in all three arms.
Other Name: Naropin

Detailed Description:

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.
