Cardiovascular and respiratory alterations in dogs during cervical myelography using ioversol

Subarachnoid infusion of most contrast mediums and the steps involved in performing a cervical myelography have adverse affects that can discourage its use in the radiographic diagnosis of spinal cord diseases. Thus, the cardiovascular and respiratory alterations associated with neck flexion, subarachnoid puncture, and cerebrospinal fluid drainage during subarachnoid infusion of ioversol (320mgI/mL) in dogs under general anesthesia using isoflurane were evaluated. The dogs received subarachnoid infusion of autologous cerebrospinal fluid kept at 38°C - control group (GC); ioversol 0.3mL/kg at 25°C (GI25) and ioversol 0.3mL/kg heated to 38°C (GI38). Each dog had its heart rate (HR), systolic arterial pressure (SAP), diastolic arterial pressure (DAP), respiratory rate (RR), oxyhemoglobin saturation (SaO2) and electrocardiography readings (PR and QT intervals) recorded. Group comparisons showed no statistical difference regarding neck positioning, subarachnoid puncture, and subarachnoid infusion of contrast medium on HR, RR and SaO2, cardiac rhythm or conduction. However, isoflurane significantly increased PR and QT intervals. Based on these findings, it is concluded that the steps involved in cervical myelography and the use of ioversol 320mgI/mL at 0.3mL/kg (25ºC and 38ºC) during cervical myelography did not result in relevant cardiovascular and respiratory alterations, except for an elevation in arterial pressure after injection of ioversol.

Interação de crenças em contexto colaborativo virtual de aprendizagem de línguas

This article mainly aims at addressing issues of the complexity and dynamics of beliefs in collaborative contexts for language teaching and learning, such as Teletandem. On the assumption that beliefs are dynamic and can be (re)signified, we present some of the results of a research about the interaction of beliefs of two Teletandem partners, a Brazilian and an Italian undergraduate student, addressing moments of convergence and divergence, as well as their possible origins and (re)significations from lived experiences. The results show how the Teletandem context can become a field for conflicts and clashes of beliefs and how the mediation as well as the relationship between the participants becomes essential for the conduction of language learning in collaborative environments.
