Randomized Controlled Trial
Thoracic Paravertebral Blockade Reduces Chronic Postsurgical Pain in Breast Cancer Patients: A Randomized Controlled Trial.
To evaluate the effect of multilevel single-shot thoracic paravertebral blockade (PVB) on the occurrence of chronic postsurgical pain (CPSP) in patients undergoing breast cancer surgery. ⋯ For patients undergoing breast cancer surgery, multilevel single-shot PVB reduces the incidence of CPSP at six months; it also improves early postoperative analgesia and reduces neuropathic pain at six and 12 months after surgery.

Orthopedic procedures involving the hip have remained challenging for regional anesthesia given the complex innervation, painful nature contributing to difficulty positioning, and a desire to maintain mobility to hasten postoperative recovery. The revision total hip arthroplasty (THA) poses a greater challenge for an effective regional analgesia due to complex surgical approach, scarring from previous surgery and limited patient mobility. ⋯ There is no standard of care regional anesthesia technique for hip surgeries, and the regional practice varies widely among anesthesia providers. This retrospective case series studied the effect of combining the QL with PENG block on the revision THA analgesia.

Paravertebral block reduces pain in elderly patients with percutaneous nephrolithotomy: A randomized controlled study protocol.
To assess the effectiveness of paravertebral block for the percutaneous nephrolithotomy (PCNL) patients. ⋯ In comparison with traditional analgesia, the ultrasound-guided paraventric block is an effective analgesic approach in PCNL, and no additional complications are encountered.

Clinical Trial
Minimum effective volume of ropivacaine for ultrasound-guided supra-inguinal fascia iliaca compartment block.
Supra inguinal fascia iliaca compartment block (FICB) is increasingly used in elderly patients with hip fractures. However, the minimum effective volume of local anesthetics required for ultrasound-guided supra-inguinal FICB has not been determined. With ethical committee approval and written informed consent from patients, we studied 21 consecutive patients of ASA physical status I-III undergoing surgery for hip fracture who met the inclusion criteria. ⋯ EV50 and EV95 of 0.25% ropivacaine for ultrasound-guided supra-inguinal FICB calculated with logistic regression analysis were 15.01 ml (95% confidence interval, 6.53-22.99 ml) and 26.99 ml (95% confidence interval, 20.54-84.09 ml), respectively. EV50 and EV95 of 0.25% ropivacaine for ultrasound-guided supra-inguinal FICB were 15.01 ml and 26.99 ml, respectively.
