exsanguination/potassium

Selective termination by intracardiac potassium chloride injection was performed in twins discordant for hydrocephaly at 20 weeks' gestation. Because of the potential for vascular anastomoses to exist between the twins, fetal angiography was performed prior to the selective termination procedure.

Selective reduction (SR) via intravascular potassium chloride (KCl) injection is contraindicated in monochorionic twins due to the presence of placental vascular communications, which may serve as a conduit for inter-twin passage of KCl or allow exsanguination of the living twin into the demised

We and others frequently have noted serum potassium levels of 8.0 +/- 0.85 mEq/L or greater in laboratory mice; this concentration has even been published as the upper limit of a 'normal' reference range. However, if bone fide, this potassium concentration would be incompatible with life in all

The aim of the study was to determine changes of serum cortisol and biochemical, haematological and antioxidant enzyme variables in the blood of horses sampled during the pre-slaughter period (in the lairage and in the stunning box) and during exsanguination. A total of 24 Slovenian warm-blooded

Extracellular K+ activity (Ke), local tissue blood flow and the cortical evoked potential (EP) were measured concurrently in the cerebral cortex of baboons anaesthetised with a-chloralose. Flows were progressively reduced from normal by occlusion of the middle cerebral artery and controlled steps of

OBJECTIVE To investigate the effects of the long-term oral administration of L-arginine on the impaired neurogenic and endothelium-dependent relaxation responses of corpus cavernosum smooth muscle from alloxan-induced diabetic rabbits. METHODS Thirty-two New Zealand white rabbits were used in four

BACKGROUND The objective of this study was to evaluate different tests of heart viability in a pig model of warm ischemia. RESULTS Pig hearts (n = 30) were submitted to 0 (= group I), 10 (group II), 20 (group III), 30 (group IV), and 60 (group V) minutes of in situ warm ischemia (animal

In this study naturally occurring hypertension in wild rhesus monkeys has been noted with a frequency of 13 out of 428 monkeys examined. The maximum systolic/diastolic blood pressure was 242/140 mm of Hg. Clinically there was evidence of grade I retinopathy in one case only, otherwise the animals

OBJECTIVE Our goal was to develop the most comprehensive database possible to counsel patients about selective termination for fetal abnormalities, because no one center has sufficient data to assess much more than crude loss rates. METHODS A total of 183 completed cases of selective termination

Rats were scalded on one hind limb and sacrificed by exsanguination at 4 hours, 1 day, and 3 days postburn. Concentrations of sodium, potassium, calcium, magnesium, and phosphate were measured in serum and in calf muscles from the burned and unburned limb of burned rats and controls. At 4 hours

1. Samples of cisternal cerebrospinal fluid (c.s.f.) and blood plasma have been obtained nearly simultaneously from foetal sheep of different ages, the foetus having been exteriorized and maintained in a normal state with respect to its blood gases and arterial pH. The brains were removed from these

The primary goal of this study is to determine the effects of Mn exposure via inhalation. The bioaccumulation of Mn in different organs and tissues, the alteration of biochemical parameters, and the locomotor activity were assessed. A group of 26 male Sprague-Dawley rats (E) were exposed to 3750

Despite the increasing interest in the welfare of animals during transport, very little is known on the response of local pig breeds to the transport procedures. This study aims to compare the effect of short journey on behaviour, blood parameters, and meat quality traits in 51 Apulo-Calabrese and

OBJECTIVE The aim of this study is to evaluate the early survival and organ damage following 30 and 60 min of thoracic resuscitative endovascular balloon occlusion of the aorta (REBOA) in an ovine model of severe hemorrhagic shock. METHODS Eighteen sheep were induced into shock by undergoing a 35 %

Hemodialysis patients may die suddenly and unexpectedly from a number of causes. These may be divided into those deaths due directly to and occurring during hemodialysis, those deaths occurring while the patient is not undergoing dialysis, and those deaths that may occur at any time. The first group
