BACKGROUND: Regional anesthesia is of benefit for outpatient surgery given its demonstrated improvement in analgesia and decrease in complications, resulting in shorter average recovery room times and lower hospital readmission rates. Unfortunately, there are few epidemiological studies outlining the overall utilization of peripheral nerve blocks (PNBs) in this setting. Therefore, the primary objective of this study was to report the overall utilization of several types of PNBs among all candidate cases in the outpatient setting within the United States...

BACKGROUND: Perineural dexamethasone has gained popularity in regional anesthesia to prolong analgesia duration. However, uncertainty remains regarding the optimal perineural dose. Clarification of this characteristic is of significant importance as the administration of dexamethasone may lead to dose-dependent complications. The objective of this meta-analysis was to define the optimal perineural dexamethasone dose to prolong analgesia after brachial plexus blockade for adult patients undergoing upper limb surgery...

Regional plexus and nerve blocks are a common technique in modern anesthesia. Since ultrasound machines are available in many departments, the role of nerve stimulation is highly discussed and different approaches to perform the blocks are taken into account. Common technique for electrical nerve stimulation is searching for a stimulating threshold of 0.4-0.5mA using an impulse width of 0.1ms. We present our hypothesis of using all possible information with a new concept of protective nerve stimulation together with first data supporting our theory...

We describe the clinical presentation of a patient with spastic diplegia, and its unique perioperative challenges. Opioids and antispasmodic medications are the primary therapy for managing pain and spasticity in the perioperative setting. However, such combination results in several side-effects and their sedative properties are synergistic. A 64-year-old woman with a history of spastic diplegia and an intrathecal baclofen pump for the treatment of her lower extremity spasticity was scheduled for a third elective left knee arthroplasty...

OBJECTIVE: The goal of this study was to analyze whether tympanic plexus neurectomy is a successful surgical option in patients with intractable otalgia. STUDY DESIGN: A retrospective single institution study from the experience of two surgeons was conducted. METHODS: Records of adult patients with intractable unilateral otalgia of likely glossopharyngeal origin were reviewed, with institutional review board approval. Patients who responded to a tympanic plexus block were considered for tympanic neurectomy...

Organ growth requires the coordinated invasion and expansion of blood vessel networks directed by tissue-resident cells and morphogenetic cues. A striking example of this intercellular communication is the vascularization of the central nervous system (CNS), which is driven by neuronal progenitors, including neuroepithelial cells and radial glia. Although the importance of neuronal progenitors in vascular development within the CNS is well recognized, how these progenitors regulate the vasculature outside the CNS remains largely unknown...

Background: Supraclavicular nerve block is a popular approach for anaesthesia for upper limb surgeries. Conventional methods for evaluation of block success are time consuming and need patient cooperation. The aim of this study was to evaluate whether the perfusion index (PI) can be used to predict and provide a cut-off value for ultrasound-guided supraclavicular nerve block success. Methods: The study included 77 patients undergoing elective orthopaedic procedures under ultrasound-guided supraclavicular nerve block...

Current therapies for reducing raised intracranial pressure (ICP) under conditions such as idiopathic intracranial hypertension or hydrocephalus have limited efficacy and tolerability. Thus, there is a pressing need to identify alternative drugs. Glucagon-like peptide-1 receptor (GLP-1R) agonists are used to treat diabetes and promote weight loss but have also been shown to affect fluid homeostasis in the kidney. We investigated whether exendin-4, a GLP-1R agonist, is able to modulate cerebrospinal fluid (CSF) secretion at the choroid plexus and subsequently reduce ICP in rats...

INTRODUCTION: The pain from upper gastrointestinal malignancy leads to considerable morbidity. The celiac plexus and splanchnic nerve neurolysis are good therapeutic options. Although splanchnic nerve neurolysis less frequently performed, but it has an edge over celiac plexus as it can be performed in patients with altered celiac plexus anatomy by enlarged lymph nodes. METHODS: The fluoroscopy-guided splanchnic nerve neurolysis was done in about 21 patients with intractable upper abdominal pain with pain intensity of ≥7 in numerical rating scale (NRS) from upper gastrointestinal cancers with distorted celiac plexus anatomy from enlarged celiac lymph nodes as seen by computed tomography scan after positive diagnostic splanchnic nerve neurolysis...

Breast surgery is exceedingly common and may result in significant acute as well as chronic pain. Numerous options exist for the control of perioperative breast pain, including several newly described regional anesthesia techniques, but anesthesiologists have an insufficient understanding of the anatomy of the breast, the anatomic structures disrupted by the various breast surgeries, and the theoretical and experimental evidence supporting the use of the various analgesic options. In this article, we review the anatomy of the breast, common breast surgeries and their potential anatomic sources of pain, and analgesic techniques for managing perioperative pain...

BACKGROUND AND OBJECTIVES: Psoas blocks are an alternative to femoral nerve blocks and have the potential advantage of blocking the entire lumbar plexus. However, the psoas muscle is located deeply, making psoas blocks more difficult than femoral blocks. In contrast, while femoral blocks are generally easy to perform, the inguinal region is prone to infection. We thus tested the hypothesis that psoas blocks are associated with more insertion-related complications than femoral blocks but have fewer catheter-related infections...

The proton-coupled folate transporter (PCFT-SLC46A1) is required for intestinal folate absorption and folate transport across the choroid plexus. This report addresses the structure/function of the 8th transmembrane helix. Based upon biotinylation of cysteine-substituted residues by MTSEA-biotin, 14 contiguous exofacial residues to Leu316 were accessible to the extracellular compartment of the 23 residues in this helix (Leu303-Leu325). Pemetrexed blocked biotinylation of six Cys-substituted residues deep within the helix implicating an important role for this region in folate binding...

The brachial plexus is commonly blocked at the interscalene level for shoulder and proximal humeral surgery. There are only a few publications about the interscalene technique in pediatric patients for a peripheral nerve block. Ultrasound-guided peripheral nerve block has become increasingly more popular for pediatric patients because of high success rates and safety concerns. We used ultrasound-guided interscalene brachial plexus block in an 18-month-old child with an acute upper respiratory infection who had a supracondylar fracture of the humerus...

BACKGROUND AND AIMS: The supraclavicular and infraclavicular brachial plexus blocks have a similar distribution of anaesthesia, and both can be used effectively for surgeries of the upper limb. This study aimed to compare the supraclavicular and infraclavicular approaches of brachial plexus blocks, guided by ultrasound and neurostimulation. METHODS: Sixty adult patients scheduled for elective upper limb surgery of the elbow and/or below were randomly divided into two groups: infraclavicular Group (I) and supraclavicular Group (S)...

REVIEW
Dajie Wang
PURPOSE OF REVIEW: Chronic abdominal pain is a complex medical condition. The causes of chronic abdominal pain are extremely diverse ranging from chronic pancreatitis, Crohn's disease, to chronic pain with no clear etiology. Treatment of chronic abdominal pain remains a challenge in our clinical practice. While current interventions with celiac plexus blocks and pain medications provide some relief for these patients, but these treatments are typically less efficacious and limited by various adverse effects...
