Table 2

Time to the rescue analgesia, the total analgesic consumption, and the number of patients who requested rescue analgesia.

	Group L	Group LK	value
Time to the first rescue analgesia (h)	6.5 ± 2.4	18.7 ± 4.8	<0.001
	6 (4–12)	18 (12–24)
Total analgesic consumption (mg)	5.86 ± 3.6	1.14 ± 2.2	<0.001
Number of patients who requested rescue analgesia (%)	19 (76%)	6 (24%)	0.001

L- levobupivacaine, LK- levobupivacaine + ketamine. Data are expressed as mean ± SD (standard deviation), median (range), or patient number (percentage (%)). is considered significant.
