Abstract
|
|
|
Changes in arterial oxygen tension after operation have excited much interest and concern among anesthesiologist and surgeons. In the present study, an effort was made to evaluate the degree of hypoxemia in the early recovery period with general anesthesia.
The 75 patients were chosen in each of the following groups-upper abdominal, lower abdominal and non-abdominal operations.
The arterial blood samples were taken preoperatively and than immediately, 15, 30, 45, 60 minutes after arrival in the recovery room.
The results were as follows:
1) There are more significant decrease of PaO2, SaO2, pH and increase of PaCO2 in the upper abdominal operation group (p<0.01), than other groups.
2) There are significant decrease of PaO2, pH and increase of PaCO2 (p<0.01) but no significant changes of Sa02 in the lower abdominal operation group.
3) There are significant decrease of PaO2(p < 0.05), pH (p < 0.01) and increase PaCO2 (p < 0.01)but no significant changes of SaO2 in the non-abdominal operation group.
As a result of this study, it was suggested that conservative and safe management of post-operative patients is better to provide supplement oxygen in the early recovery period to upper abdominal operative patients under gone general anesthesia.
