Summary: | Indwelling central venous catheters are often used to facilitate frequent phlebotomy while minimizing stress and anesthetic effects on animals. However, nonhuman primates with central venous catheters must wear protective jackets. Jackets routinely are removed for aerosol exposure to
agents and respiratory measurements by whole-body plethysmography (WBP) because of the potentially confounding effects of jackets on these procedures. However, removing the jacket may dislodge the catheter, making it unusable. Using each animal as its own control, we tested 12 African green
monkeys to determine whether minute volume, tidal volume, respiratory rate, or accumulated volume measurements by WBP differed depending on whether the animal wore a protective jacket or not. We found no statistical differences in any measured respiratory parameter and concluded that the jackets
could be left in place on the animal while undergoing plethysmography without compromising the calculations for determining the inhaled dose of aerosolized agent. In addition, this study revealed no obvious contraindications to leaving the jacket in place in other nonhuman primate species,
provided that the jacket fits appropriately and that plethysmography is performed correctly. |
