What is the central question of this study? In this study we sought to investigate whether cardiovascular responses to peripheral chemoreflex activation of rats recovered from protein restriction are related to AT1 receptors activation. What is the main finding and its importance? This study highlights the fact that angiotensinergic mechanisms activated by AT1 receptors do not supported increased responses to peripheral chemoreflex activation by KCN in rats recovered from protein restriction. Also, we found that protein restriction led to increased resting ventilation in adult rats, even after recovery...

Maintenance of central venous access in patients with chronic medical conditions such as short bowel syndrome demands forethought and ingenuity. We describe an innovative technique for re-utilizing central venous access sites in patients who have chronic central venous access needs. Records of patients undergoing this technique were reviewed between August 2012 and December 2015. The technique involves "cutting-down" to the sterile fibrous tunnel that naturally forms around tunneled catheters. The fibrous sheath is then isolated and controlled much as would be done for a venous "cut-down...

BACKGROUND: Children undergoing computerized tomography (CT) frequently require sedation to allay their anxiety, and prevent motion artifacts and stress of intravenous (IV) cannulation. AIMS: The aim of this trial was to compare the effectiveness of oral midazolam and intranasal dexmedetomidine as sole premedicants in children for carrying out both IV cannulation as well as CT scanning, without the need for additional IV sedatives. METHODS: Fifty-nine children, aged 1-6 years, scheduled to undergo CT imaging under sedation were randomized to receive either 0...

Intravenous cannulation is becoming one of the most common procedures in healthcare as increasing numbers of patients are treated for acute and chronic illnesses. The use of an intravenous cannula is not without risk, so it is essential that the healthcare practitioner can justify why the patient requires cannulation, as well as being able to safely manage and provide ongoing care for patients with the device. This article provides an overview of intravenous cannulation, including the selection of appropriate cannulation sites, identification of the different types and sizes of cannula used, and cannula maintenance...

Restraint is often perceived as necessary to ensure that medical procedures are carried out safely. The limited research into nurses' perceptions of restraint practices with hospitalized children hinders understanding the extent of the problem. A survey design was used to investigate nurses' perceptions of restraint use from five units in one children's hospital in Ireland. Findings revealed that restraint is a common practice, with physical and psycho- logical restraints most commonly used and newborn to 4-year-old children most likely to be restrained...

BACKGROUND: Retinal ischemia is a retinal disorder related to retinal vascular occlusion, glaucoma, diabetic retinopathy and age-related macular degeneration. The study aimed to evaluate the protective effects and underlying mechanisms of Chi-Ju-Di-Huang-Wan (CJDHW) against retinal ischemia in rats. METHODS: High intraocular pressure (HIOP)-induced retinal ischemia was established in Wistar rats by raising their intraocular pressure to 120 mmHg for 60 min with in an eye whose anterior chamber was cannulated with a 30-guage needle adapted to a normal saline bottle through an intravenous line...

Intravenous (IV) cannulation and sterile IV salt solutions may not be options in resource-limited settings (RLSs). This article presents recipes for fluid resuscitation in the aftermath of burns occurring in RLSs. Burns of 20% total body surface area (TBSA) can be resuscitated, and burns up to 40% TBSA can most likely be resuscitated, using oral resuscitation solutions (ORSs) with salt supplementation. Without IV therapy, fluid resuscitation for larger burns may only be possible with ORSs. Published global experience is limited, and the magnitude of burn injuries that successfully respond to World Health Organization ORSs is not well-described...

PURPOSE: Recent histological data suggest autonomic innervation of the central retinal artery. In the present study, we investigated the effect of electrical brain stem stimulation at the superior salivatory nucleus (SSN) on the retinal vessel diameter in rats and whether nitric oxide mediates a possible effect. METHODS: Sprague-Dawley rats (n = 12) were anesthetized using pentobarbital sodium (50 mg/kg intraperitoneally). The animals were artificially ventilated and the femoral artery and vein were cannulated for blood pressure measurement and drug administration...

BACKGROUND: Dietary n-3 and n-6 polyunsaturated fatty acids (PUFAs) have an impact on insulin secretion and sensitivity but whether and how these may be related to maternal glucose homeostasis during pregnancy is unclear. METHODS: Female Wistar rats (240-250 g) were assigned to laboratory CHOW or high fat diets rich in either n-6 (safflower oil; n-6 group) or n-6 + n-3 (safflower oil + fish oil; n-3 group) PUFAs. After 10 days half of the animals in each diet group were inseminated and confirmed pregnant...

Peripheral intravenous cannulation in children is associated with occasional morbidity. We present a case where a large volume of blood, administered through a small peripheral cannula in the antecubital fossa, was found to have extravasated into the soft tissues, causing catastrophic vascular compromise. The expedient removal of the extravasate using a lipoaspiration cannula restored perfusion immediately to the affected limb and negated the need for surgical fasciotomies.

The present study sought to determine cardiovascular effects of aerobic training associated with diminazene aceturate (DIZE), an activator of the angiotensin converting enzyme 2, in spontaneously hypertensive rats (SHRs). Male SHRs (280-350 g) were either subjected to exercise training or not (sedentary group). The trained group was subjected to 8 weeks of aerobic training on a treadmill (five times a week, lasting 60 min at an intensity of 50-60% of maximum aerobic speed). In the last 15 days of the experimental protocol, these groups were redistributed into four groups: i) sedentary SHRs with daily treatment of 1 mg/kg DIZE (S+D1); ii) trained SHRs with daily treatment of 1 mg/kg DIZE (T+D1); iii) sedentary SHRs with daily treatment of vehicle (S+V); and iv) trained SHRs with daily treatment of vehicle (T+V)...

PURPOSE: Determine the pharmacokinetics of insulin peglispro (BIL) in 5/6-nephrectomized rats and study the absorption in lymph duct cannulated (LDC) sheep. METHODS: BIL is insulin lispro modified with 20-kDa linear PEG at lysine B28 increasing the hydrodynamic size to 4-fold larger than insulin lispro. Pharmacokinetics of BIL and insulin lispro after IV administration were compared in 5/6-nephrectomized and sham rats. BIL was administered IV or SC into the interdigital space of the hind leg, and peripheral lymph and/or serum samples were collected from both LDC and non-LDC sheep to determine pharmacokinetics and absorption route of BIL...

INTRODUCTION: Children who are subjected to surgical treatment for scoliosis usually end up receiving a lot of blood transfusions since they tend to lose one or more blood volumes during the surgery. Tranexamic acid is an antifibrinolytic agent, increasingly used in children to reduce perioperative blood loss in various settings, including corrective surgery of scoliosis. CASE REPORT: A 12-year-old girl, weighing 44 kg, was admitted to our hospital for scoliosis correction...
