BACKGROUND: Many surgeons and emergentologists use non-ultrasound-guided wrist nerve blocks. There is little evidence to guide the ideal volume of local anesthesia or how long we should wait after injection before performing pain-free procedures. This pilot study examined time to maximal anesthesia to painful needle stick in 14 volunteer participants receiving bilateral wrist blocks of 6 versus 11 mL of local. METHODS: One surgeon performed all 14 bilateral wrist median nerve blocks in participants who remained blinded until after bandages were applied to their wrist...

REVIEW
H J Scholten, A Pourtaherian, N Mihajlovic, H H M Korsten, R A Bouwman
Ultrasound guidance is becoming standard practice for needle-based interventions in anaesthetic practice, such as vascular access and peripheral nerve blocks. However, difficulties in aligning the needle and the transducer can lead to incorrect identification of the needle tip, possibly damaging structures not visible on the ultrasound screen. Additional techniques specifically developed to aid alignment of needle and probe or identification of the needle tip are now available. In this scoping review, advantages and limitations of the following categories of those solutions are presented: needle guides; alterations to needle or needle tip; three- and four-dimensional ultrasound; magnetism, electromagnetic or GPS systems; optical tracking; augmented (virtual) reality; robotic assistance; and automated (computerised) needle detection...

BACKGROUND AND OBJECTIVES: Ultrasound-guided transversus abdominis plane block demonstrated efficacy in providing post-operative analgesia by prolonging the time to first analgesic requirement and reducing the total analgesic consumption. The surgical transversus abdominis plane block, a novel technique, can be performed safely in obese patients in whom muscle layers cannot be sufficiently exposed. Here, we compared applicability, efficacy and complications of surgical transversus abdominis plane and ultrasound-guided transversus abdominis plane blocks in obese pregnant women following cesarean section under general anesthesia...

BACKGROUND: Thoracic paravertebral block can provide analgesia for unilateral chest surgery and is associated with a low complication rate. Horner syndrome also referred to as oculosympathetic paresis, is a classic neurologic constellation of ipsilateral blepharoptosis, pupillary miosis, and facial anhidrosis resulting from disruption of the sympathetic pathway supplying the head, eye, and neck. CASE REPORT: We present a patient with an ipsilateral transient Horner syndrome after ultrasound guided single shot of 15mL 0...

The quadratus lumborum (QL) block facilitates the administration of anaesthesia to the anterior abdominal wall. The use of ultrasound (US) improves the accuracy of the QL block and reduces the risk of adverse events. Electromyography (EMG) in combination with US for muscle plane blocks has not been described previously. We postulated that the addition of EMG-guided needle positioning might assist the execution of this block. This case report describes the first use of combined needle EMG and US to carry out a QL block performed for postoperative analgesia following an open appendicectomy...

BACKGROUND: Adenoid cystic carcinoma (ACC) of the larynx and trachea is very rare. CASE: A 45-year-old man with ACC of the larynx presenting as a thyroid mass is reported in this study. Physical examination revealed a large solid thyroid nodule in the left lobe without any lymphadenopathy. A technetium thyroid scan showed multinodular goiter with cold nodules in the left lobe, isthmus, and functioning nodules in the right lobe. A large thyroid mass originating from the left side of the larynx, mostly the left vocal cord and the infraglottic part, was seen using enhanced magnetic resonance imaging after rupture of the thyroid cartilage on the left side...

OBJECTIVES: Transversus abdominis plane (TAP) block for postoperative analgesia in laparoscopic cholecystectomy is usually given under ultrasound guidance. Laparoscopic-assisted TAP block has been suggested as an alternative to ultrasonogram (USG)-guided block as it is less time consuming and does not need extra equipments. This study was done to compare the efficacy of both the techniques. PATIENTS AND METHODS: We conducted a randomized controlled trial between October 2012 and June 2014 involving adult patients with symptomatic gall stone disease...

BACKGROUND: Few studies were performed to compare ultrasound guided brachial plexus block with procedural sedation for reduction of shoulder dislocations in the Emergency Department (ED). This study was done to provide further evidence regarding this comparison. METHODS: This was a randomized clinical trial performed on patients presenting with anterior shoulder dislocations to the emergency department of an academic level 2 trauma center. Exclusion criteria were any contraindications to the drugs used, any patient which may not be potentially assigned into both groups because of an underlying medical condition, presence of neurovascular compromise related to the dislocation, presence of concomitant fractures, and patient refusal to participate in the study...

In recent years, the technique of combined ultrasound and electrical stimulation-guided nerve block has been recommended. We present 2 patients with Duchenne muscular dystrophy who exhibited different muscle responses to nerve stimulation during the performance of peripheral nerve blocks for surgeries. Whereas a 2-year-old boy without severe disability showed the expected muscle contraction to electrical nerve stimulation, a 14-year-old boy with severe disability showed no muscle response. Our experience suggests that muscle responses to electrical nerve stimulation will vary with the stage of Duchenne muscular dystrophy...

Hyuckgoo Kim, Sun Ok Song, Gul Jung
Recent reports suggest that ultrasound-guided stellate ganglion block (SGB) is safer and more accurate than classic SGB by the using the surface anatomical landmark. However, previous reports concern the classic paratracheal approach using a small specialized curved probe, which may not be appropriate in some patients. The authors have attempted several approaches, including paratracheal, trans-thyroidal, lateral paracarotid, and lateral approaches, to find a safe and suitable method for real-time ultrasound-guided SGB using a standard high-frequency linear probe...

Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is the procedure of choice for the cytologic diagnosis of pancreatic masses. The specificity of EUS-FNA approaches 100%, but the sensitivity is still low, and the high rate of indeterminate (atypical and suspicious) and false-negative results needs improvement. KRAS gene is frequently mutated in pancreatic ductal adenocarcinoma (PDAC) (up to 90%), and mutation analysis of KRAS has been proposed as diagnostic biomarker of PDAC. In most laboratories, KRAS mutation testing is performed by Sanger sequencing or real time-quantitative polymerase chain reaction (RT-qPCR), but these methods may give false-negative results in routine samples, mainly due to low cellularity...
