3. Results
A total of 68 patients scheduled for arthroscopic knee surgery were
evaluated. 4 patients refused to participate in the study, 3 patients
were excluded due to antipsychotic use and 1 patient was excluded
because of possible tramadol allergy history. Descriptive data such as
age, gender, ASA class, body mass index, surgery type and duration and
evaluations between groups are given in TABLE 1. There was no
significant difference between the groups in terms of the distribution
of descriptive data (p> 0.05).
All operations were completed uneventfully and there were no recorded
postoperative complications. One time arterial puncture occurred during
the block procedures, the procedure was continued and the case was
included in the study. No complications such as quadriceps weakness,
intramuscular hematoma, LAST etc. reported in the postoperative period
were observed.
When the groups were compared in terms of fentanyl requirements in the
recovery room, fentanyl requirement was observed in 7 patients in the
control group, while fentanyl was required in 2 and 1 patients in the
ACB-0.25 and ACB-0.16 groups, respectively, and the difference between
the groups was statistically significant (p <0.05). There was
no difference between the groups in terms of rescue analgesic
requirements in the first 12 hours and the second 12 hours
(p> 0.05).
However, when the groups were compared, a statistical difference was
found in terms of the tramadol requirements of the patients in the first
12 hours, the second 12 hours, and the first 24 hours (p
<0.05). The use of tramadol in both block groups was lower
than the control group in all time periods (p <0.01), and
there was no statistically significant difference between the block
groups (p> 0.05). Analgesic requirements for the first 24
hours are shown in Table 2, and tramadol requirements for 24 hours are
shown in figure 2.
When the average pain scores of the groups were compared, a difference
was determined between the groups at 30th minute, 1st hour, 2nd hour and
3rd hour (p <0.001), while there was no difference at 6th,
12th and 24th hours. In the intergroup evaluation, it was determined
that the pain score in the control group at 30th minute, 1st hour, 2nd
hour and 3rd hour was higher than the block groups (p <0.001),
and there was no difference between the block groups in these times
(p> 0.05) (Table 3) .
