Abstract.
Fifteen patients undergoing surgery and receiving volatile anesthesia with isoflurane were enrolled as the study group. At the same time, 15 patients undergoing surgery with intravenous anesthesia drugs were included as a control group to compare each other. Before surgery, 1 h after surgery, and 1 week after surgery, we investigated these two groups of patients with technetium-99m–labeled diethylene triamine pentaacetic acid radioaerosol inhalation lung scan (DTPA lung scan), a test to evaluate lung ventilation (LV), which was evaluated by the first and equilibrium lung ventilation image and alveolar epithelial permeability (AP) which was evaluated by the half time (T1/2, minutes) of Tc-99m DTPA radioaerosol lung clearance. No significant change and abnormality of LV before surgery, 1 h after surgery, or 1 week after surgery was found in either group of patients. In addition, no significant change in AP before surgery (T1/2 = 64.0 ± 17.3 min), 1 h after surgery (64.5 ± 19.6 min), or 1 week after surgery (63.6 ± 17.6 min) was found among the control group patients (p values > 0.05). However, a significant transient increase in AP was found in the study group 1 h after surgery (71.7 ± 17.5 versus 51.2 ± 16.4 min), but it recovered 1 week after surgery (51.2 ± 16.4 versus 70.9 ± 16.0 min) (p values < 0.05). We conclude that volatile anesthesia with isoflurane can induce transient increase of AP.
