BACKGROUND Prone position during general anesthesia for special surgical operations may be related with increased airway pressure, decreased pulmonary and thoracic compliance that may be explained by restriction of chest expansion and compression of abdomen. The optimum ventilation mode for anesthetized patients on prone position was not described and… (More)
OBJECTIVE The local anesthetics may cause neurotoxicity. We aimed to compare the neurotoxic potential of different local anesthetics, local anesthetic induced nerve damage and pathological changes of a peripheral nerve. METHODS Sixty Wistar rats weighing 200-350g were studied. Rats were assigned into 3 groups and 26-gauge needle was inserted under… (More)
Pressure-controlled ventilation (PCV) is less frequently employed in general anesthesia. With its high and decelerating inspiratory flow, PCV has faster tidal volume delivery and different gas distribution. The same tidal volume setting, delivered by PCV versus volume-controlled ventilation (VCV), will result in a lower peak airway pressure and reduced risk… (More)
Avaliação da lesão do nervo ciático após injeção intraneural de bupivacaína, levobupivacaína e lidocaína em ratos (15%) e seis no grupo lidocaína (30%). Conclusão: Em todos os grupos, a frequência de dano histopatológico e de gravidade foi maior do que a deficiência motora.
Pulse oximetry is a frequently used tool in anesthesia practice. Gives valuable information about arterial oxygen content, tissue perfusion and heart beat rate. In this study we aimed to provide the comparison of peripheral capillary hemoglobin oxygen saturation (SpO2) values among every finger of the two hands. Thirty-seven healthy volunteers from… (More)
OBJECTIVE Laryngoscopy and stimuli inside the trachea cause an intense sympatho-adrenal response. Remifentanil seems to be the optimal opioid for rigid bronchoscopy due to its potent and short-acting properties. The purpose of this study was to compare bolus propofol and ketamine as an adjuvant to remifentanil-based total intravenous anesthesia for… (More)
