25. Anesthetic effects on tadpoles and post-metamorphic frogs of bullfrog (Lithobates catesbeianus) / Efeito de anestésicos em girinos e rãs pós-metamórficas de rã-touro (Lithobates catesbeianus)
Com o intuito de avaliar o uso de três anestésicos locais, entres eles, o eugenol, o mentol e a benzocaína, como indutores à sedação e à insensibilização de girinos e rãs pós-metamórficas da espécie Lithobates catesbeianus, em diferentes estágios de desenvolvimento, realizou-se este experimento no Laboratório do Ranário Experimental da Univer

26. Uso de Lidocaína e Bupivacaína na anestesia espinhal em Trachemys dorbignyi (Duméril &Bibron, 1835) (Testudines-Emydidae)
We aimed to investigate the efficacy of lidocaine and bupivacaine via spinal injection in promoting sensory and motor block in the regions of the tail/cloaca and pelvic members of Trachemys dorbignyi. Ten females with average weight of 1.375 kilograms (kg) were submitted to two anesthetic protocols, with an interval of 10 days: 4.6 milligrams (mg)/kg of lido

27. 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

28. Glucose levels and hemodynamic changes in patients submitted to routine dental treatment with and without local anesthesia
OBJECTIVE: The aim of this study was to (1) observe the extent to which hemodynamic and glucose measurements change in patients submitted to a dental procedure with and without a local anesthetic and a vasoconstrictor (LAVA; 2% mepivacaine with adrenaline 1100,000) and (2) correlate those parameters with the patients' anxiety levels. METHOD: This was an unbl

29. Efeitos da infusão profilática contínua de fenilefrina sobre a estratégia de redução da massa de anestésico local em pacientes submetidas à raquianestesia para cesariana. / Effects of prophylactic continuous infusion of phenylephrine on the strategic use of reduced dose of local anesthetics in elective cesarean patients undergoing spinal anesthesia.
Background: Reduced local anesthetic dose is used for minimizing hypotension changes related with spinal anesthesia for cesarean section, optimizing both maternal and fetal outcomes. This strategy can result in neuroaxial block failure. On the other hand, the higher doses associated with hypotension can be controlled with continuous prophylactic infusion of

30. Efeito analgésico periférico do tramadol em ratos / Local analgesic effect of tramadol in rats
INTRODUCTION: Tramadol is a centrally and peripherally-acting drug, found as a racemic mixture of two enantiomers (+) and (-)-tramadol and effective in the treatment of moderate to severe pain. Tramadol has an -opioid effect ten times less potent than codeine. After first pass metabolism, tramadol is metabolized to various compounds and its major metabolites

31. ConcentraÃÃes plasmÃticas de mepivacaÃna em pacientes submetidos à cirurgia de terceiros molares
Surgical removal of the third molars in clinical regime making use of local anesthetics plays a great role in the everyday practice of odontology. These drugs are safe when used in the proper way, but they can lead to undesirable outcomes when used in the wrong quantities or concentrations. Based on the knowledge of such principle and on surgical clinical pr

32. Efeitos dos anestesicos locais na transmissão neuromuscular e no bloqueio produzido pelo rocuronio : estudo experimental / The effects of local anesthetics on the neuromuscular transmission and on the blockade produced by rocuronium : experimental study
Local anesthetics can interact with neuromuscular blockers and modify their pharmacokinetics and pharmacodynamics properties but this mechanism of interaction is very controversial. This experimental study performed in rat phrenic nerve diaphragm preparation and chick biventer cervicis muscle, had the objective to evaluate the effect of different local anest

33. Desenvolvimento de formulações semi-sólidas contendo anestésicos locais em sistemas nanoparticulados
Objectives: This work aimed to develop and characterize semi-solid formulations containing local anesthetics freely dispersed or entrapped in solid lipid nanoparticles and to evaluate in vivo the analgesic effect of these formulations through tail flick method. Methods: Three semi-solid formulations (gel, cream-gel and silicone emulsion) containing free loca

34. Uso da ropivacaína ou levobupivacaína na anestesia epidural toraco-lombar em cães
Based on current progress of the anesthetic techniques, it is necessary to experiment with new local anesthetics. Ropivacaine and levobupivacaine are recent formulations of long duration, the amide group, which have lower toxicity that bupivacaine. The thoracic epidural anesthesia is still little explored in Veterinary Medicine today. The purpose of this stu

35. Molecular dynamics of articaine in POPC membranes / Dinamica molecular de articaina em membranas POPC
We studied the interactions of articaine - a local anesthetic widely used for me- dical and odontological applications - with model membranes of POPC (palmitoyl-oleyl-phosphatidylcholine) at biological relevant conditions. We have employed molecular dynamics technique, which allowed us to investigate the system at molecular level. Firstly, we applied quantum

36. Efeitos cardiovasculares da lidocaína com epinefrina injetada concomitantemente à hialuronidase 75 utr/ml em bloqueio do nervo alveolar inferior / Cardiovascular effects of lidocaine with epinephrine injected concomitantly to hialuronidase 75 TRU/mL in inferior alveolar nerve block
A hialuronidase é uma enzima utilizada em anestesias oftalmológicas com o intuito de melhorar a eficácia anestésica. No entanto, como a hialuronidase aumenta a difusão do anestésico local injetado tanto para o feixe nervoso quanto para a circulação sistêmica, podendo causar alterações nos parâmetros cardiovasculares. O objetivo deste estudo contr
