Randomized Controlled Trial Comparative Study
A comparison of the continuous supraclavicular brachial plexus block using the proximal longitudinal oblique approach and the interscalene brachial plexus block for arthroscopic shoulder surgery: A randomised, controlled, double-blind trial.
Continuous interscalene brachial plexus block (ISB) is widely used for arthroscopic shoulder surgery, but the incidence of hemidiaphragmatic paresis (HDP) has been reported to reach 100%. Several methods, including injections distal to the C5-C6 nerve roots, have been attempted to reduce the HDP incidence. However, catheter placement distal to the C5-C6 nerve roots interferes with the surgical site. ⋯ For major shoulder surgery, compared with continuous ISB, continuous PLO-SCB was more sparing of diaphragmatic and respiratory function while providing noninferior analgesia. Catheter placement via the PLO approach is feasible without interfering with the surgical field.

Hidradenitis suppurativa (HS) is a painful, chronic inflammatory skin condition. Patients experience exacerbations, leading them to present to the emergency department (ED) for incision and drainage. Direct injection of local anesthetic into these lesions is extremely painful and seldom provides adequate anesthesia. A modified method of the PECS II block can provide anesthesia to the skin of the axilla, making management of HS much less painful for the patient. We performed a bilateral modified PECS II block on a patient requiring incision and drainage of HS lesions in both axillae. She subsequently required no local anesthetic for the procedure. ⋯ A modified technique of the PECS II block, in which only the second injection is performed, is a potentially effective method for anesthetizing the axilla of patients with HS prior to incision and drainage.
