Extended oxygen supplementation after thoracotomy in rats may improve welfare.
A retrospective comparison of welfare indicators in male rats undergoing thoracotomy for intrapleural dosing is presented. The initial cohort (n = 7) breathed room air after recovery from anaesthesia, while later cohorts (n = 12) had oxygen supplementation for up to 48 h post-surgery. Rats breathing room air sustained a statistically significant average body-weight loss of -1.62% (±1.7%) 2 days after surgery, compared with rats given oxygen supplementation, which maintained a mean weight gain of 0.87% (±1.75%) (p = 0.009). Oxygen-supplemented rats also had lower pain scores on the evening after surgery (median 0.075 [range 0-1.75] vs. median 1.5 [range 0.5-2]). This difference was not statistically significant (p = 0.063) but may be of clinical significance. All rats displayed transient sedation after post-operative opioid administration on the day of surgery, and hypoxaemia (SpO2 <90%) was observed in rats maintained on room air. Use of an oxygen concentrator to provide post-operative extended oxygen supplementation was easy to implement and may improve animal welfare post-thoracotomy.
期刊介绍：
The international journal of laboratory animal science and welfare, Laboratory Animals publishes peer-reviewed original papers and reviews on all aspects of the use of animals in biomedical research. The journal promotes improvements in the welfare or well-being of the animals used, it particularly focuses on research that reduces the number of animals used or which replaces animal models with in vitro alternatives.
