Review Meta Analysis
Analgesic benefits and clinical role of the posterior suprascapular nerve block in shoulder surgery: a systematic review, meta-analysis and trial sequential analysis.
Although suprascapular nerve block reduces nausea & vomiting and improves patient satisfaction after shoulder surgery when compared to morphine alone, it results only in clinically insignificant objective improvement of analgesia.

Review Meta Analysis
Local anaesthetic delivery regimens for peripheral nerve catheters: a systematic review and network meta-analysis.
There are numerous possible techniques for delivering local anaesthetic through peripheral nerve catheters. These include continuous infusions, patient-controlled boluses and programmed intermittent boluses. The optimal delivery regimen of local anaesthetic is yet to be conclusively established. ⋯ Sub-group analysis revealed that these findings were mostly confined to lower limb and truncal catheter studies; there were few studies of programmed intermittent boluses for upper limb catheters. Programmed intermittent boluses may provide optimal delivery of a local anaesthetic through peripheral nerve catheters. Further research is warranted, particularly to delineate the differences between upper and lower limb catheter locations, which will help clarify the clinical relevance of these findings.
