Effects of Permissive Hypercapnia on Laparoscopic Surgery for Rectal Carcinoma

Table 2

The ventilatory parameters in the three groups at T1 and T2.

	High hypercapnia group ()	Low hypercapnia group ()	Control group ()	value
Peak pressure (cmH2O)
T1				0.36
T2	^#			<0.01
Plateau pressure (cmH2O)
T1				0.81
T2	^#			<0.01
Dynamic compliance (ml/cmH2O)
T1				0.58
T2	^#			<0.01

T1 = before operation; T2 = 30 min after pneumoperitoneum. Compared with control group; ^#compared with low hypercapnia group.
