Key result
The modified GATB (M) test showed significant differences from baseline up to 3.5 hours after general anesthesia, but control group performance indicated this test lacks reliability.
Why the study?
Does the modified GATB (M) test reliably measure recovery from general anesthesia in post-surgical patients?
Does the modified GATB (M) test reliably measure recovery from general anesthesia in post-surgical patients?
The modified GATB (M) test is not a reliable measure of recovery from general anesthesia.
Caution against using modified GATB (M) for post-anesthesia recovery assessment; leaves open validation of reliable cognitive tests in surgical cohorts.
23 patients were evaluated following surgery under general anesthesia with enflurane or halothane. Data on the M tests of the modified GATB gave significant differences 1 ½, 2 ½, and 3 ½ hr. after the end of the period of anesthesia when compared with the baseline. The performance of a control group shows lack of reliability of this form of the test.

Letourneau et al. (1983) studied this question. The modified GATB (M) test showed significant differences from baseline up to 3.5 hours after general anesthesia, but control group performance indicated this test lacks reliability.
