BACKGROUND: Injection of local anesthetic into the transversus abdominis plane (TAP block) decreases systemic morphine requirements after abdominal surgery. We compared intraoperative surgeon-administered TAP block (surgical TAP) to anesthesiologist-administered transcutaneous ultrasound-guided TAP block (conventional TAP) for post-cesarean analgesia. We hypothesized that surgical TAP blocks would take less time to perform than conventional TAP blocks. METHODS: We performed a randomized trial, recruiting 41 women undergoing cesarean delivery under neuraxial anesthesia, assigning them to either surgical TAP block (n=20) or conventional TAP block (n=21)...

Background and objectives Unmyelinated C-fibres comprise the largest group of somatic afferents and have demonstrated a crucial role not only in the perception of high-threshold mechanically, thermally or chemically induced pain, but also in non-harmful low-threshold mechanical stimuli [1,2]. The objective of our study was to characterize differential sensitivity changes of C-fibre related subclasses of high-threshold and low-threshold polymodal nociceptors and low-threshold mechanoreceptors to the local anaesthetic (LA) mepivacaine during nerve block of the purely sensory lateral femoral cutaneous nerve (LFCN) in human...

STUDY OBJECTIVE: Laparoscopic cholecystectomy (LC) is a commonly performed minimally invasive procedure that has led to a decrease in procedure-related mortality and morbidity. However, LC requires analgesia that blocks both visceral and somatic nerve fibers. In this study, we evaluated the effectiveness of Erector Spinae Plane Block (ESPB) for postoperative analgesia management in LC. DESIGN: Single-blinded, prospective, randomized, efficiency study. SETTING: Tertiary university hospital, postoperative recovery room & ward...

Background Trigeminal neuralgia is a neuropathic disorder characterized by episodes of intense pain in the face. Drug therapy is the first choice of treatment. However, in cases where drug therapy are contraindicated due to side effects, patients can get pain relief from lengthy neurosurgical procedures. Alternatively, a peripheral trigeminal nerve block can be easily performed in an outpatient setting. Therefore it is a useful treatment option for the acute paroxysmal period of TN in patients who cannot use drug therapy...

BACKGROUND AND OBJECTIVES: For superficial surgery of anteromedial and posteromedial surfaces of the upper arm, the medial brachial cutaneous nerve (MBCN) and the intercostobrachial nerve (ICBN) must be selectively blocked, in addition to an axillary brachial plexus block. We compared efficacy of ultrasound-guided (USG) versus conventional block of the MBCN and the ICBN. METHODS: Eighty-four patients, undergoing upper limb surgery, were randomized to receive either USG (n = 42) or conventional (n = 42) block of the MBCN and the ICBN with 1% mepivacaine...

BACKGROUND AND OBJECTIVES: Percutaneous peripheral nerve stimulation (PNS) is an analgesic modality involving the insertion of a lead through an introducing needle followed by the delivery of electric current. This modality has been reported to treat chronic pain as well as postoperative pain the day following knee surgery. However, it remains unknown if this analgesic technique may be used in ambulatory subjects following foot procedures beginning within the recovery room immediately following surgery, and with only short series of patients reported to date, the only available data are derived from strictly observational studies...

Isaacs syndrome is a rare peripheral nerve hyperexcitability syndrome. The painful discharges in Isaacs syndrome are abolished by the blockade of the neuromuscular junction but not by peripheral nerve blocks (PNB). However, the efficacy of PNB for intraoperative and postoperative analgesia among those with Isaacs syndrome is unknown. A 41-year-old woman with Isaacs syndrome underwent open reduction and internal fixation of radius fractures. Ultrasound-guided bilateral axillary brachial plexus blocks were performed, followed by general anesthesia...

BACKGROUND: Pain following bariatric surgery can be quite troublesome and prolongs recovery. Transversus abdominis plane (TAP) block is a new regional anesthetic technique to reduce postoperative pain and is an important part of current analgesic regimen for many abdominal surgeries. The primary objective of our study was to assess the efficacy of the TAP block in controlling postoperative pain in laparoscopic sleeve gastrectomy. Secondary outcomes assessed in this study were postoperative nausea and vomiting (PONV), time to ambulate, readiness for discharge, and whether it leads to improved patient satisfaction...

Numerous publications have emerged on the application of erector spinae plane block in adult population. There are few reports of the use of this block in pediatric patients. The objective is to report 2 cases of adolescents, one diagnosed with pectus excavatum and the other one with pectus carinatum undergoing reconstructive surgery in which a bilateral single-shot erector spinae plane block was performed as an analgesic technique. The block was performed before surgery under general anesthesia in lateral decubitus position, guided by ultrasound using 20ml of 0...

BACKGROUND: Ultrasound, nerve stimulation, and their combination are all considered acceptable ways to guide peripheral nerve blocks. Which approach is most effective and associated with the fewest complications is unknown. We therefore used a large registry to analyze whether there are differences in vascular punctures, multiple skin punctures, and unintended paresthesia. METHODS: Twenty-six thousand seven hundred and thirty-three cases were extracted from the 25-center German Network for Regional Anesthesia registry between 2007 and 2016 and grouped into ultrasound-guided puncture (n = 10,380), ultrasound combined with nerve stimulation (n=8173), and nerve stimulation alone (n = 8180)...

Objectives: The pectoral nerve block type II (PECS II block) is widely used for postoperative analgesia after breast surgery. This study evaluated the analgesic efficacy of PECS II block in patients undergoing breast-conserving surgery (BCS) and sentinel lymph node biopsy (SNB). Methods: Patients were randomized to the control group ( n =40) and the PECS II group ( n =40). An ultrasound-guided PECS II block was performed after induction of anesthesia. The primary outcome measure was opioid consumption, and the secondary outcome was pain at the breast and axillary measured using the Numerical Rating Scale (NRS) 24 hours after surgery...

Injection pressure monitoring provides valuable information to prevent intraneural injections and possibly consequent nerve damage during peripheral nerve block. However, the measurement of injection pressure along the injection line is inaccurate as it is influenced by several variables. The aim of this study was to test a new system for precise injection pressure monitoring at the needle tip in a cadaveric model. The system consists of a miniaturised pressure sensor embedded within the needle shaft that is connected via an optical fibre to an external control unit...

Animal data have demonstrated increased block duration after local anaesthetic injections in diabetic rat models. Whether the same is true in humans is currently undefined. We, therefore, undertook this prospective cohort study to test the hypothesis that type-2 diabetic patients suffering from diabetic peripheral neuropathy would have increased block duration after ultrasound-guided popliteal sciatic nerve block when compared with patients without neuropathy. Thirty-three type-2 diabetic patients with neuropathy and 23 non-diabetic control patients, scheduled for fore-foot surgery, were included prospectively...

Background: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is an established modality for the assessment of mediastinal and hilar adenopathy. To overcome the sampling limitations of standard 21- and 22-gauge EBUS-TBNA needles, a new flexible 19-gauge (Flex 19G) needle was developed. Methods: We performed a retrospective analysis of patients who underwent EBUS-TBNA sampling with the Flex 19G needle. A 22G needle was always used first for cytology, followed by a Flex 19G needle, either an early version (Oct/2014-Sep/2015) or a final version needle (May/2016-Jan/2017), for tissue sampling...
