1. Efeitos do uso de vasoconstritores no bloqueio de nervos digitais: revisão sistemática com metanálise
RESUMO Convencionalmente, a associação de anestésicos locais com vasoconstritores é evitada em extremidades pelo risco de isquemia. Entretanto, estudos recentes sugerem haver segurança no uso de vasoconstritor em extremidades. Procuramos, assim, avaliar a efetividade e segurança do uso de vasoconstritores combinados com anestésicos locais no bloqueio

4. Gender differences in microcirculation: Observation using the hamster cheek pouch
OBJECTIVES: Estrogen has been shown to play an important protective role in non-reproductive systems, such as the cardiovascular system. Our aim was to observe gender differences in vivo with regard to the increase in macromolecular permeability and leukocyte-endothelium interaction induced by ischemia/reperfusion as well as in microvascular reactivity to v

5. Comparison of hemodynamic effects of lidocaine, prilocaine and mepivacaine solutions without vasoconstrictor in hypertensive patients
OBJECTIVE: Local anesthetic solutions with vasoconstrictors are not contraindicated in hypertensive patients, but due to their hemodynamic effects, local anesthetics without vasoconstrictors are mainly preferred by the clinicians. The aim of this study was to compare hemodynamic effects of three different local anesthetics without vasoconstrictors during too

6. Acute lead-induced vasoconstriction in the vascular beds of isolated perfused rat tails is endothelium-dependent
Chronic lead exposure induces hypertension in humans and animals, affecting endothelial function. However, studies concerning acute cardiovascular effects are lacking. We investigated the effects of acute administration of a high concentration of lead acetate (100 µΜ) on the pressor response to phenylephrine (PHE) in the tail vascular bed of male Wistar ra

7. Alterations in the Renin-Angiotensin System in the contralateral carotid artery after balloon catheter injury / Alterações do Sistema Renina-Angiotensina na artéria carótida contralateral à lesão por cateter balão
Fifteen days after balloon catheter injury Emax of Ang II was increased in the contralateral artery as compared to values obtained in arteries from intact animals. This increase in Ang II Emax was not modified in the absence of the endothelium. The morphological and morphometric characteristics in the contralateral artery were not altered as compared to cont

8. Estudo dos efeitos da injeção intravascular de drogas vasoconstrictoras, presentes nas soluções anestésicas locais, sobre a pressão arterial de ratos normotensos, hipertensos renais um-rim, um clip (1R-1C) e 1R-1C tratados com atenolol / Pressure effects of vasoconstrictors in normotensive, 1K-1C hypertensive and 1K-1C rats treated with atenolol
O presente trabalho teve como objetivo analisar e comparar o efeito de agentes vasoconstrictores presentes nas soluções anestésicas locais, injetados por via intravenosa nas doses de 80, 160, 320, 640 e 1280 ng (adrenalina) ou 0.5, 1, 2, 3 e 4 UI (felipressina), sobre a pressão arterial de ratos, hipertensos renais um-rim, um clip (1R-1C) e 1R-1C tratado

9. Consequências dos tratamentos realizados com celecoxibe, -tocoferol ou losartan sobre a reatividade em carótidas de ratos submetidos à lesão com cateter balão / Consequences of the treatments performed with celecoxib, -tocopherol or losartan on the carotid of reactivity in rats subjected to injury with balloon catheter.
The injury by balloon catheter is a procedure commonly used to study the mechanisms of restenosis. The mechanical stress produced by the passage of the balloon promotes changes both in the injured artery in the contralateral artery. There was an increased density of neurons containing neuropeptides such as substance P (SP) and the Gene Related Peptide of Cal

10. Anestesia loco-regional para tratamento odontológico em pacientes cardiopatas: estudo comparativo entre lidocaína 2% sem adrenalina e lidocaína 2% com adrenalina 1:100.000 / Loco-regional anesthesia for cardiac patients odontologic treatment: comparative study between plain lidocaine 2% and lidocaine 2% with epinephrine 1:100.000
Introduction: This prospective, randomized double-blinded study investigated hemodynamic changes in valvular cardiac patients during dental treatment with the use of a local anesthesia containing epinephrine. Methods: The study was conducted in the Dental Department of the Instituto do Coração do Hospital das Clínicas da Faculdade de Medicina da Universid

12. Cardiovascular changes in hypertensive patients undergoing dental treatment under local anesthesia with vasoconstrictors / Avaliação de parametros cardiovasculares em pacientes hipertensos submetidos a tratamento odontologico sob anestesia local com vasoconstritor
This double-blind crossover study evaluated cardiovascular parameters of twenty hypertensive patients under periodontal treatment with 3.6 ml of 2% lidocaine with 1:100,000 epinephrine or 3% prilocaine with 0.03UI/ml felypressin. Heart rate (HR), systolic (SBP), and diastolic (DBP) arterial blood pressures were recorded before, during and after the dental tr
