To evaluate the effect of the duration of general anesthesia and surgery on the postoperative recovery, the 66patients with oral-maxillofacial surgery were divided into 5 experimental groups.
According to he duration of anesthesia and surgery, the patients who had the 2 hours, 2 to 3 hours, 3 to 4 hours, 4 to 5 hours duration of anesthesia and surgery and more than 5 hours duration of anesthesia and surgery were allocated as a patient
of
experimental group A, B, C, D or E.
The recovery indexes such as patient's mobility, respiratory status, change of systolic blood pressure, status of consciousness and skin colour were used to measure the patient's recovery state immediately after arriving on postoperative recovery
area,
and to measure the time to score the 10 points (full recovery state) of the recovery indexes in the postoperative area. Also the total duration of the patient's staying at postoperative area was measured.
@ES The following results were obtained:
@EN 1. There were no significant difference in patients from experimental group A to D on the average scores of the recovery indexes immediately after arriving on the postoperative recovery area.
2. In patients of experimental group E, the scores of the recovery indexes were significantly lower than the patients of any other experimental group.
3. The average full recovery time of the patients in the experimental group A was significantly shorter than the patients of any other experimental group.
4. The average full recovery time in patients of the experimental group B was also significantly shorter than the patients of experimental group E.
5. There was no significant changes on the average total duration of the patient's staying at the postoperative area in the patients of the experimental group A and B, but these patients were significantly shorter than the patients of the
experimental
group C, D or E on the patient's average total duration of staying at the postoperative area.
