Validez y confiabilidad de la versión en español de la escala multidimensional de la UNESP-Botucatu para evaluar el dolor postoperatorio en gatos

This study focused on the validation of the Spanish version of the UNESP-Botucatu multidimensional composite pain scale to assess postoperative pain in cats. The original scale in Portuguese was translated into Spanish by two independent translators, and summarised in one version by a third individual. The summarised version was back-translated and minor adjustments were made. The scale was reviewed by three anesthesiologists with Spanish as their first language, and the final version was submitted to psychometric testing. Thirty cats undergoing ovariohysterectomy were video recorded during the perioperative period. Six observers from different spanish speaking countries, who had Spanish as the first language watched the videos and determined the pain scores using the Spanish version of the scale, identifying the cats that should receive analgesics. Videos were reanalysed in a different order about 2 months after the first assessment. The sensitivity to change, content and construct validity were established by the significant change in pain scores in response to surgery and analgesics. The agreement between the evaluations of the 'gold standard'(researcher that developed the scale) and the other observers confirmed the criterion validity. Inter- and intra-rater reliability, evaluated by intra-class correlation coefficient, ranged from good to very good for all scale items. The cut-off point for rescue analgesia identified by Receiver Operating Characteristic curve was > 7 with 92% of sensitivity and 91% of specificity. The Spanish version of the UNESP-Botucatu multidimensional composite pain scale is interpretable (has an optimal analgesic intervention score), valid and reliable instrument for assessing acute pain in cats undergoing ovariohysterectomy.

The Lanz® endotracheal tube decreases tracheal injury in dogs

Purpose: To determine, in dogs anesthetized with nitrous oxide (N2O), whether the endotracheal tube (ETT) cuffed with a Lanz® pressure regulating valve decreases the tracheal consequences of tracheal intubation. Methods: Sixteen mixed-breed dogs were allocated to two groups according to the ETT used: Control group (n = 8) - Rüsch ETT, and Lanz group (n = 8) - ETT with Lanz® pressure regulating valve. The ETT cuffs in both groups were inflated with air to an intracuff pressure of 30 cm H2O. Anesthesia was induced and maintained with pentobarbitone and N2O (1.5 L·min-1) and O2 (1 L·min-1). ETT cuff pressures were measured before (control) and 60, 120, and 180 min during N2O administration. The dogs were sacrificed, and biopsy specimens from four predetermined areas of the tracheal mucosa in contact with the ETT were collected for light and scanning electron microscopy (SM) examination. Results: Cuff pressures in the Control group were higher than in the Lanz group at all time points studied (P < 0.001), with an increase over time only in the Control group (P < 0.001). Median neutrophilic inflammatory infiltration values of the epithelial surface, and in the subepithelial layer in contact with the cuff, were higher in the Control group as compared to the Lanz group (3.0 vs 1.0 and 3.0 vs 1.5 respectively) (P < 0.05). On SM examination, median histological grades were higher in the Control group compared to Lanz group (2.9 vs 1.9 respectively), (P < 0.05). Conclusions: The Lanz® ETT decreases tracheal mucosal injury in dogs.
