INTRODUCTION: Pectoral Nerves Block (PECS) and Serratus Plane Block (SPB) have been used to treat persistent post-surgical pain after breast and thoracic surgery, however they cannot block the internal mammary region, so a residual pain may occur in that region. Parasternal block (PSB) and Thoracic Transversus Plane Block (TTP) anesthetize the anterior branches of T2-6 intercostal nerves thus they can provide analgesia to the internal mammary region. METHODS: We describe a 60-year-old man suffering from right post thoracotomy pain syndrome with residual pain located in the internal mammary region after a successful treatment with PECS and SPB We performed a PSB and TTP and hydrodissection of fascial planes with triamcinolone and Ropivacaine...

BACKGROUND: A continuous adductor canal block provides analgesia after surgical procedures of the knee. Recent neuroanatomic descriptions of the thigh and knee led us to speculate that local anesthetic deposited in the distal thigh close to the adductor hiatus would provide superior analgesia compared to a more proximal catheter location. We therefore tested the hypothesis that during a continuous adductor canal nerve block, postoperative analgesia would be improved by placing the perineural catheter tip 2-3 cm cephalad to where the femoral artery descends posteriorly to the adductor hiatus (distal location) compared to a more proximal location at the midpoint between the anterior superior iliac spine and the superior border of the patella (proximal location)...

The posterior antebrachial cutaneous nerve branches from the radial nerve proximal to the elbow and supplies sensation to the posterior aspect of the forearm. With a high-frequency linear transducer, the posterior antebrachial cutaneous nerve was identified in 8 healthy volunteers. Under aseptic conditions and with an ultrasound-guided in-plane technique, 1% lidocaine was injected circumferentially around the nerve. In each participant, the block was successful, and neither incidental blocks of other nerves nor any other complications were observed...

BACKGROUND: Adductor canal block (ACB) is a peripheral nerve blockade technique that provides good pain control in patients undergoing total knee arthroplasty which however does not relieve posterior knee pain. The recent technique of an ultrasound-guided local anesthetic infiltration of the interspace between popliteal artery and the capsule of posterior knee (IPACK) has shown promising results in providing significant posterior knee analgesia without affecting the motor nerves. MATERIALS AND METHODS: A prospective study was conducted from September 2016 to March 2017 in a total of 120 patients undergoing unilateral total knee arthroplasty...

David Terence Thomas, Serkan Tulgar
Erector spinae plane block (ESP) is a recently described regional anesthesia technique that leads to the blockage of both visceral and somatic nerve fibers. While there are anecdotal reports of ESP used in children, none are for laparoscopic procedures. Herein we report a child undergoing laparoscopic cholecystectomy in which ESP was used as part of multimodal anesthesia. Ultrasound-guided ESP block is an easily performed peripheral nerve block that leads to long-lasting postoperative analgesia. It can be successfully used in pediatric laparoscopic procedures such as cholecystectomy and should be kept in mind as an option for multimodal analgesia in children...

Point-of-care ultrasonography has become widely used in diagnosis and managements of patients. In the field of anesthesiology, ultrasound guided nerve blocks and central venous catheterization (CVC), and transesophageal echocardiography (TEE) have become popular. Now, ultrasound devices are familiar to anesthesiologists. In pre-anesthetic patient risk evaluation, the sonographic results of transthoracic echocardiography (TTE) or the examination of deep venous thrombus are often helpful for anesthesia planning...

Spectral analysis of ultrasound radiofrequency backscatter has the potential to identify intercostal blood vessels during ultrasound-guided placement of paravertebral nerve blocks and intercostal nerve blocks. Autoregressive models were used for spectral estimation, and bandwidth, autoregressive order and region-of-interest size were evaluated. Eight spectral parameters were calculated and used to create random forests. An autoregressive order of 10, bandwidth of 6 dB and region-of-interest size of 1.0 mm resulted in the minimum out-of-bag error...
