Objective: To address whether spontaneous inhalation of 50% nitrous oxide (N2O) for up to 30 minutes adversely affects swine with pneumothorax (PNTX).
Methods: Five fasted, female swine (13-17 kg) were sedated with IV ketamine, intubated, and allowed to spontaneously inhale either 50% N2O or room air (RA) in a sequential crossover design in which each animal served as its own RA control. Small (group 1, 150 mL), medium (group II, 300 mL), and large (group III, 500 mL) PNTXs were created by instilling air into the left pleural space via an 18-Fr three-way Foley catheter.
