Safety and effectiveness of propofol sedation during and after outpatient colonoscopy

Table 2 Relationship between age or sex and dose of propofol used in 2101 patients who underwent colonoscopy

Age (yr)	No. (M/F)	Propofol dose (mg)			P value
		Total (range)	Male	Female
20-401	150 (89/61)	115.3 ± 32 (40-200)	113.4 ± 27	118.2 ± 24	0.43
41-60	563 (316/247)	107.7 ± 27 (40-200)	106.9 ± 28	108.7 ± 25	0.19
≥ 61	1388 (744/644)	89.7 ± 21 (40-200)	87.7 ± 23	92.1 ± 19	0.32
Total	2101 (1149/952)	96.4 ± 27	95.0 ± 26	98.1 ± 25	0.18

Values are mean ± SD except for number of patients and range of dose used of propofol. P value shows the difference between male and female patients.

¹There were significant differences in the doses of propofol in each group between age 20-40 and ≥ 61 years (P < 0.001).
