BACKGROUND: Perioperative pain, increased sympathetic tone, and peripheral vasospasm may be safely managed with regional nerve blockade during microvascular reconstruction in the lower extremity. Limited reports exist in this setting; therefore, we evaluated our use of peripheral nerve catheters (PNCs) during microvascular limb salvage to determine safety and efficacy for both patient and flap. METHODS: A single-institution, retrospective review of a prospectively maintained database on all patients with lower extremity free tissue transfers between 2012 and 2017 was completed...

Subcutaneous infusion, or hypodermoclysis, is a technique whereby fluids are infused into the subcutaneous space via small-gauge needles that are typically inserted into the thighs, abdomen, back, or arms. In this review, we provide an overview of the technique, summarize findings from studies that have examined the use of subcutaneous infusion of fluids for hydration or nutrition, and describe the indications, advantages, and disadvantages of subcutaneous infusion. Taken together, the available evidence suggests that, when indicated, subcutaneous infusion can be effective for administering fluids for hydration or nutrition, with minimal complications, and has similar effectiveness and safety to the intravenous route...

AIMS: We examined the efficacy of tramadol on the urethral reflex during sneezing, as well as the role of µ-opioid receptors in the spinal cord, in rats. METHODS: Forty-one female Sprague-Dawley rats were used. The rats were divided into normal female rats and rats with vaginal distension (VD), which mimics stress urinary incontinence (SUI) in humans. Under urethane anesthesia, the sneeze-induced amplitude of urethral responses (AUR) and baseline pressure (BP) were examined after intravenous injection of tramadol using a microtransducer-tipped catheter in both rat groups...

This work explains the motivation, advantages, and novel approach of using velocity magnetic resonance imaging (MRI) for studying the hydrodynamics in a complicated structural biomedical device such as an intravenous catheter needleless connector (NC). MRI was applied as a non-invasive and non-destructive technique to evaluate the fluid dynamics associated with various internal designs of the NC. Spatial velocity maps of fluid flow at specific locations within these medical devices were acquired. Dynamic MRI is demonstrated as an effective method to quantify flow patterns and fluid dynamic dependence on structural features of NCs...

Hypertension is the leading modifiable risk factor for death worldwide, yet the causes remain unclear and treatment remains suboptimal. Catheter-based renal denervation (RDNX) is a promising new treatment for resistant hypertension, but the mechanisms underlying its antihypertensive effect remain unclear. We recently found that RDNX attenuates deoxycorticosterone acetate-salt hypertension and that this is dependent on ablation of afferent renal nerves and is associated with decreased renal inflammation. To determine if this is common to other models of salt-sensitive hypertension, rats underwent complete RDNX (n = 8), selective ablation of afferent renal nerves (n = 8), or sham denervation (n = 8)...

Blood glucose and its variability of is a major prognostic factor associated with morbidity. We hypothesized that intravenous microdialysis incorporated in a central venous catheter (CVC) would be interchangeable with changes in blood glucose measured by the reference method using a blood gas analyzer. Microdialysis and central venous blood glucose measurements were simultaneously recorded in high-risk cardiac surgical patients. The correlation between absolute values was determined by linear regression and the Bland-Altman test for repeated measurements was used to compare bias, precision, and limits of agreement...

Central venous catheters (CVCs) are ubiquitous in the healthcare industry and carry two common complications, catheter related infections and occlusion, particularly by thrombus. Catheter-related bloodstream infections (CRBSI) are an important cause of nosocomial infections that increase patient morbidity, mortality, and hospital cost. Innovative design strategies for intravenous catheters can help reduce these preventable infections. Antimicrobial coatings can play a major role in preventing disease. These coatings can be divided into two major categories: drug eluting and non-drug eluting...

REVIEW
Philip Allan, Simon Lal
Intestinal failure (IF) is the inability of the gut to absorb necessary water, macronutrients (carbohydrate, protein, and fat), micronutrients, and electrolytes sufficient to sustain life and requiring intravenous supplementation or replacement. Acute IF (types 1 and 2) is the initial phase of the illness and may last for weeks to a few months, and chronic IF (type 3) from months to years. The challenge of caring for patients with IF is not merely the management of the underlying condition leading to IF or the correct provision of appropriate nutrition or both but also the prevention of complications, whether thromboembolic phenomenon (for example, venous occlusion), central venous catheter-related bloodstream infection, IF-associated liver disease, or metabolic bone disease...

RATIONALE: Preclinical studies consistently report that aerobic exercise decreases drug self-administration and other forms of drug-seeking behavior; however, relatively few studies have examined other types of physical activity. OBJECTIVES: The purpose of the present study was to examine the effects of resistance exercise (i.e., strength training) on heroin self-administration and mRNA expression of genes known to mediate opioid reinforcement and addictive behavior in the nucleus accumbens (NAc) of heroin-exposed rats...

BACKGROUND: Modern endovascular thrombectomy (MET), using stent retrievers or large-bore distal aspiration catheters in stroke patients with acute basilar artery occlusion (BAO), is routinely performed to date. However, more than 35% of BAO patients treated with MET die within 90 days despite high recanalization rates. The purpose of this study is to investigate the parameters associated with 90-day mortality in patients with BAO after MET. METHODS: We analyzed 117 consecutive BAO patients included in the Endovascular Treatment in Ischemic Stroke prospective clinical registry of consecutive acute ischemic stroke patients treated with MET (60 patients [51...

Acetylcholine is the main transmitter of the parasympathetic vagus nerve. According to the cholinergic anti-inflammatory pathway (CAP) concept, acetylcholine has been shown to be important for signal transmission within the immune system and also for a variety of other functions throughout the organism. The spleen is thought to play an important role in regulating the CAP. In contrast, the existence of a "non-neuronal cardiac cholinergic system" that influences cardiac innervation during inflammation has been hypothesized, with recent publications introducing the heart instead of the spleen as a possible interface between the immune and nervous systems...

Diagnosis and treatment of attention-deficit/hyperactivity disorder (ADHD) has risen drastically over the past 20 years in the United States and abroad. Amphetamine-based prescription stimulants are the most prescribed treatment for ADHD and the diversion of these drugs has also increased. Reports indicate 61% of individuals with an ADHD medication prescription have sold or shared their medication. Exposure to prescription stimulants, especially for those without an ADHD diagnosis, may increase susceptibility to drugs of abuse...

We describe three cases of inadvertent placement of the urinary catheter into the ureter. An 85-year-old gentleman on long-term indwelling catheter (IDC) for neurogenic bladder presented with fever and right flank pain. CT of abdomen and pelvis demonstrated the tip of the IDC to be located within the right vesicoureteric junction with acute right hydronephrosis and acute pyelonephritis. A 74-year-old woman, on long-term IDC for neurogenic bladder was found to have hydronephrosis on ultrasound imaging. Contrast-enhanced CT intravenous pyelography done subsequently showed the IDC was in the right distal ureter...

Cortisol levels reflect hypothalamic-pituitary-adrenocortical (HPA) axis activity. While most plasma cortisol is supposed to be bound to the soluble cortisol binding globulin (CBG), only free cortisol (FC) actively regulates metabolic and immunological processes. We aimed to establish a multi-species suitable method to assess FC in cows and horses which in combination with total cortisol (TC) allows interpreting proportional changes of cortisol in saliva as well as in blood in response to a standardized HPA axis activation via ACTH...

We report here the isolation of Mucor velutinosus from multiple blood cultures performed on samples from Broviac catheters and culture of a Broviac insertion-site wound sample from a 6-year-old boy with a history of intestinal failure secondary to chronic intestinal pseudo-obstruction, parenteral nutrition, and jejunostomy tube dependence. Examination of a slide from the culture revealed the presence of wide nonseptate hyphae with sporangiophores, columella, and chlamydospores. The fungal isolate was sent to the National Institutes of Health for further evaluation and was identified as Mucor velutinosus by matrix-assisted laser desorption ionization-time-of-flight mass spectrometry and genomic sequencing...
