Independent samples t-tests were used to analyze group differences.

Due to unequal variances, a Mann-Whitney U test was also used to examine group differences.

No significant differences were found for morphine (p = 0.239), meperidine (p = 0.750), fentanyl (p = 0.947), or length of surgery (p = 0.936). Significant differences were found for acetaminophen (p = 0.027).
