Effect of pre-warming on perioperative hypothermia during holmium laser enucleation of the prostate under spinal anesthesia: a prospective randomized controlled trial

Table 2 Core Temperature (in °C) at Each Assessment Time in the Operating Room

Time	Control	n	Pre-warming	n	Difference (CI)^b	P value^c
On arrival in the operation room	36.8 (0.1)	25	37.0 (0.1)	25	0.2 (−0.1–0.4)	0.119
Immediately after spinal induction	36.7 (0.1)	25	36.9 (0.1)	25	0.2 (0.1–0.4)	0.029
30 min after spinal induction	36.2 (0.1)	25	36.6 (0.1)	25	0.3 (0.1–0.6)	0.006
60 min after spinal induction	35.9 (0.1)	23	36.3 (0.1)	23	0.4 (0.1–0.7)	0.014
90 min after spinal induction	35.9 (0.1)	9	36.1 (0.1)	13	0.2 (−0.2–0.5)	0.706
120 min after spinal induction	35.5 (0.1)	7	35.8 (0.2)	4	0.2 (−0.3–0.8)	> 0.999
Overall effect^a					0.2 (0.1–0.4)	0.005

^aOverall mean difference in core temperatures between control and pre-warming groups intraoperatively
^bConfidence intervals (CIs) were adjusted for multiple comparisons using the Bonferroni correction; 95% CI was reported for the overall effect, and 99.2% CI was reported at each assessment time (i.e., 0.05/6)
^cP values were corrected using the Bonferroni method for multiple comparisons
