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

Table 3 Perioperative Outcomes

Outcome	Control	Pre-warming	P value
Outcome	(n = 25)	(n = 25)	P value
Hypothermia at PACU arrival	22 (88)	14 (56)	0.025
Perioperative shivering	14 (56)	4 (16)	0.007
Perioperative meperidine use	13 (52)	4 (16)	0.016
Shivering score (from 0 to 3)
Intraoperative	0 (0–0)	0 (0–0)	0.317
PACU	0 (0–1)	0 (0–0)	0.035
Thermal comfort score (from 0 to 100)
Intraoperative	40 (38–50)	40 (30–50)	0.407
PACU	35 (30–40)	40 (30–50)	0.340
Active warming required in the PACU	23 (92)	21 (88)	0.667

Values are number of patients (proportion) or median (interquartile range)
Shivering scores were based on a 4-point numerical scale: 0, none; 1, localized to the neck and core; 2, including the upper extremities; and 3, involving the entire body. Thermal comfort scores were based on a continuous verbal numerical scale: 0, extremely cold; 50, thermally neutral; and 100, extremely hot
