Pancreatite aguda de etiologia desconhecida
Acute pancreatitis of unknown etiology

J. bras. med; 103 (1), 2015
A pancreatite aguda (PA) é responsável por aproximadamente 210 mil hospitalizações por ano nos EUA, e cerca de 5% evoluem ao óbito. Após o primeiro episódio a conduta fundamental é identificar e tratar a causa, o que impedirá episódios recorrentes e mesmo a cronicidade da doença....

Métodos indicativos de estabilidade para determinação do besilato de anlodipino, nifedipino e nimodipino considerados inibidores do canal de cálcio

A hipertensão é uma doença crônica não transmissível e mais freqüente na população sendo o principal fator de risco para complicações cardiovasculares, tais como acidente vascular cerebral e infarto agudo do miocárdio. Na presente pesquisa estão sendo estudados os fármacos utilizados no tra...

Neurotoxic effects of levobupivacaine and fentanyl on rat spinal cord

Rev. bras. anestesiol; 65 (1), 2015
BACKGROUND: The purpose of the study was to compare the neurotoxic effects of intrathecally administered levobupivacaine, fentanyl and their mixture on rat spinal cord. METHODS: In experiment, there were four groups with medication and a control group. Rats were injected 15 µL saline or fentanyl 0.0005 ...

The effect of esmolol on corrected-QT interval, corrected-QT interval dispersion changes seen during anesthesia induction in hypertensive patients taking an angiotensin-converting enzyme inhibitor

Rev. bras. anestesiol; 65 (1), 2015
BACKGROUND AND OBJECTIVES: The importance of minimizing the exaggerated sympatho-adrenergic responses and QT interval and QT interval dispersion changes that may develop due to laryngoscopy and tracheal intubation during anesthesia induction in the hypertensive patients is clear. Esmolol decreases the he...

Comparison between magnesium sulfate and dexmedetomidine in controlled hypotension during functional endoscopic sinus surgery

Rev. bras. anestesiol; 65 (1), 2015
BACKGROUND AND OBJECTIVES: It is crucial to decrease bleeding during functional endoscopic sinus surgery. Our primary goal was to investigate the effects of magnesium sulfate and dexmedetomidine used for controlled hypotension on the visibility of the surgical site. METHODS: 60 patients aged between 18 a...

Effects of smoking on venous cannulation pain: a randomized prospective trial

Rev. bras. anestesiol; 65 (1), 2015
BACKGROUND AND OBJECTIVES: It has been demonstrated that smoking increases pain perception; however the effect of smoking on perception of pain during venous cannulation is not known. The purpose of this study is to determine whether or not smoking has an effect on pain perception due to peripheral venou...

Ultrasound and nerve stimulator guided continuous femoral nerve block analgesia after total knee arthroplasty: a multicenter randomized controlled study

Rev. bras. anestesiol; 65 (1), 2015
BACKGROUND AND OBJECTIVES: Postoperative analgesia is crucial for early functional excise after total knee arthroplasty. To investigate the clinical efficacy of ultrasound and nerve stimulator guided continuous femoral nerve block analgesia after total knee arthroplasty. METHODS: 46 patients with ASA gra...

Effects of various anesthesia maintenance on serum levels of selenium, copper, zinc, iron and antioxidant capacity

Rev. bras. anestesiol; 65 (1), 2015
BACKGROUND AND OBJECTIVES: In this study, we aimed to investigate the effects of sevoflurane, desflurane and propofol maintenances on serum levels of selenium, copper, zinc, iron, malondialdehyde, and glutathion peroxidase measurements, and antioxidant capacity. METHODS: 60 patients scheduled for unilate...

Evaluation of genotoxicity induced by repetitive administration of local anaesthetics: an experimental study in rats

Rev. bras. anestesiol; 65 (1), 2015
BACKGROUND AND OBJECTIVE: Previous studies regarding the effects of some local anaesthetics have suggested that these agents can cause genetic damage. However, they have not been tested for genotoxicity related to repetitive administration. The aim of this study was to evaluate the genotoxic potential of...
