PATIENTS WITH UPPER EXTREMITY SURGERY
Conditions
Keywords
Brachial Plexus Block; Nerve Block; Ultrasonography
Brief summary
The need of a neurostimulator for a successful nerve block was questioned in different block types after ultrasound has become standard. The aim of this clinical study was to determine the effect of neurostimulator use on block success in costoclavicular block
Interventions
DRUGfentanyl will be added
If adequate anagesia is not provided with the block, 1 microgram/kg of fentanyl will be added
PROCEDUREgeneral anesthesia
If adequate anagesia is not provided with the block, general anesthesia will be administered.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The block success rate (ratio of successful blocks to all blocks) | during procedure | The block was considered unsuccessful in case of analgesic need during the surgery or transition to general anesthesia, otherwise, these patients were included in the successful block group. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Block application time | 30 minutes | THE TIME BETWEEN THE NEEDLE ENTRY THROUGH THE SKIN AND THE OUTPUT OF THE NEEDLE AFTER LOCAL ANESTHETICS IS GIVEN, WAS RECORDED AS THE APPLICATION TIME |
| time to readiness for surgery | 30 minutes | Sensory and motor block levels were evaluated in the median, radial, ulnar and musculocutaneous nerve traces at 5-minute intervals for 30 minutes. An ice pack was used for sensory block evaluation. It was scored as follows; 0: completely felt; 1: has a sense of touch; no cold; 2: no sense of touch. Lateral surface of the forearm for the musculocutaneous nerve, the surface of the thumb facing the palm for the median nerve, the inner surface of the 5th finger for the ulnar nerve, and the posterior surface of the hand for the radial nerve were used for sensorial evaluation. Motor block was scored as follows; 0: full motion; 1: paresis; 2: complete block. Elbow flexion for the musculocutaneous nerve, thumb opposition for the median nerve, 5th finger abduction for the ulnar nerve, and wrist extension for the radial nerve were used to evaluate motor block. The block was considered successful if the total score was 14 or higher, with a total sensory score of at least 7. |
| number of needle passes | 30 minutes | . The number of needle passes was calculated by adding each needle advancement exceeding 10 mm to the first needle insertion. |
