Pain and immune function in patients undergoing gastric cancer surgery following stellate ganglion block with total intravenous anesthesia

Table 1 Comparison of heart rate and mean arterial pressure between the two groups at different time points

Group	Index	Before admission	Immediately after intubation	At the time of skin cutting	The 60 minutes after surgery	At the end of surgery
Observation group	HR (beats/minute)	69.82 ± 8.26	78.28 ± 7.15a,b	79.20 ± 7.24a,b	80.14 ± 7.35a,b	71.28 ± 8.61
	MAP (mmHg)	82.84 ± 6.36	92.18 ± 7.28a,b	93.58 ± 7.52a,b	92.04 ± 6.86a,b	83.10 ± 7.10
Control group	HR (beats/minute)	70.04 ± 8.28	86.86 ± 8.15a	85.82 ± 8.20a	86.20 ± 8.42a	71.08 ± 7.52
	MAP (mmHg)	83.04 ± 6.48	101.28 ± 7.58a	99.82 ± 7.50a	96.82 ± 6.96a	84.01 ± 7.15

^aP < 0.05, compared with admission within the same group.

^bP < 0.05, compared with the control group.

HR: Heart rate; MAP: Mean arterial pressure.
