BACKGROUND: Thoracic epidural anesthesia (TEA) exacerbates hypotension due to peripheral vasodilator effects following the use of general anesthetics. This study aimed to compare the hemodynamic changes caused by three different concentrations of epidural ropivacaine and to evaluate the performance of the stroke-volume variation (SVV) and central venous pressure (CVP) during TEA with general anesthesia. METHODS: A total of 120 patients were administered 8 mL of ropivacaine solution via epidural injection, following randomization into one of three groups based on the concentration of ropivacaine in the study solution: 0...

Propofol anesthesia is usually accompanied by hypotension. Studies have shown that the hypotensive effects of propofol increase in patients treated with angiotensin-converting enzyme inhibitors (ACEi). Given that both propofol and ACEi affect nitric oxide (NO) signaling, the present study tested the hypothesis that ACEi treatment induces pronounced hypotensive responses to propofol by increasing NO bioavailability. In this study we evaluated 65 patients, divided into three groups: hypertensive patients chronically treated with ACEi (HT-ACEi; n=21), hypertensive patients treated with other antihypertensive drugs instead of ACEi, such as angiotensin II receptor blockers, β-blockers or diuretics (HT; n=21) and healthy normotensive subjects (NT; n=23)...

BACKGROUND: Radial arterial cannulation is most commonly done using palpation, but the use of ultrasound has increased the cannulation success rate. This improvement, albeit significant, has not led to a very high success rate especially in trainees. A modified ultrasound technique for vascular cannulation (dynamic needle tip positioning) has been described for peripheral venous cannulation. We therefore assessed the success rate of this technique compared to the palpation technique for radial artery cannulation in adult surgical patients...

Capillary hemangioma is the most common benign vascular eyelid tumor in childhood. The periocular lesion appears within the first few weeks after birth and usually has superficial or deep components. Primary conjunctival capillary hemangiomas are rarely reported. We present the case of a 2-day-old child with a pedunculated capillary hemangioma arising from superior palpebral conjunctiva. A complete surgical excision was performed under general anesthesia, and the child was asymptomatic at follow-up of two months...

REVIEW
Olivia Nelson, Philip D Bailey
Anesthesiologists are increasingly called on to care for pediatric patients undergoing diagnostic imaging and invasive procedures in interventional radiology. These procedures are typically classified as either nonvascular or vascular, and can range from short diagnostic imaging studies or biopsies to significantly longer and more invasive intravascular procedures. Anesthesia providers must consider each child's ability to cooperate reliably during the procedure, their age, and any cognitive impairment to define the best anesthetic plan...

To investigate the effects of a xylazine infusion during isoflurane anesthesia on global perfusion parameters and gastrointestinal oxygenation and microperfusion, 8 adult warmblood horses were sedated with xylazine and anesthesia induced with midazolam and ketamine. Horses were mechanically ventilated during anesthesia. After 3 h of stable isoflurane anesthesia (FEIso 1.3 Vol %), a xylazine infusion with 1 mg/kg body weight (BW) per hour was started for 1 h and then stopped. Before, during, and after xylazine infusion, heart rate (HR), arterial blood pressure (MAP), cardiac output (CO), central venous pressure (CVP), and pulmonary artery pressure (PAP) were measured and systemic vascular resistance (SVR) was calculated...

Vascular pathology and protein accumulation contribute to cognitive decline, whereas exercise can slow vascular degeneration and improve cognitive function. Recent investigations suggest that glymphatic clearance measured in aged mice while anesthetized is enhanced following exercise. We predicted that exercise would also stimulate glymphatic activity in awake, young mice with higher baseline glymphatic function. Therefore, we assessed glymphatic function in young female C57BL/6J mice following five weeks voluntary wheel running and in sedentary mice...

BACKGROUND: Endoscopic urological procedures (transurethral resection of the prostate TURP/transurethral resection of bladder tumor TURBT) are not without risk of significant bleeding. This risk is due to the vascular nature of the tissues and their high levels of fibrinolytic enzymes in the tissues and urine. This study was conducted to evaluate the safety and efficacy of the antifibrinolytic agent tranexamic acid (TXA) in reducing blood loss in patients undergoing TURP/TURBT and transfusion requirement...
