UNASSIGNED: Although supraclavicular @entity5300 (SCBPB) was repopularized by the introduction of ultrasound, its usefulness in shoulder surgery has not been widely reported. The objective of this study was to compare motor and sensory blockades, the incidence of side effects, and intraoperative opioid analgesic requirements between SCBPB and interscalene @entity5300 (ISBPB) in @entity1 undergoing arthroscopic shoulder surgery. @entity1 were randomly assigned to 1 of 2 groups (ISBPB group: n=47; SCBPB group: n=46). The side effects of the @entity5300 ( @entity4820 , hoarseness, and subjective @entity1353 ), the sensory block score (graded from 0 [no cold sensation] to 100 [intact sensation] using an @entity285 swab) for each of the 5 dermatomes (C5-C8 and T1), and the motor block score (graded from 0 [complete paralysis] to 6 [normal muscle force]) for muscle forces corresponding to the radial, ulnar, median, and musculocutaneous nerves were evaluated 20 min after the @entity5300 . @entity3575 was administered in 50  g increments when the @entity1 complained of @entity158 that was not relieved by the @entity5300 .There were no conversions to general anesthesia due to a failed @entity5300 . The sensory block scores for the C5 to C8 dermatomes were significantly lower in the ISBPB group. However, the percentage of @entity1 who received @entity3575 was comparable between the 2 groups (27.7% [ISBPB group] and 30.4% [SCBPB group], P=0.77). SCBPB produced significantly lower motor block scores for the radial, ulnar, and median nerves than did ISBPB. A significantly higher incidence of @entity4820 was observed in the ISBPB group (59.6% [ISBPB group] and 19.6% [SCBPB group], P<0.001). No @entity1 complained of subjective @entity1353 .Despite the weaker degree of sensory blockade provided by SCBPB in comparison to ISBPB, opioid analgesic requirements are similar during arthroscopic shoulder surgery under both brachial @entity616 . However, SCBPB produces a better motor blockade and a lower incidence of @entity4820 than ISBPB.
