Table 7: Summary of Findings From Studies Reporting on the Effectiveness of BIS Monitors To Reduce Recovery Time^* (cont).

Study (year)	Basar et al. (2003) (40)	Wong et al. (2002) (31)	Bannister et al. (2001) (41)	Pavlin et al. (2001) (42)
Mean BIS values (SD)	BIS: 44.9 (5.15) SP: 40.5 (4.53)	BIS: 53 (4) SP: 47 (7)	BIS, 0–6 months: 35.7 (9.6). BIS was unexpectedly problematic in titrating anesthetic in infants younger than 6 months. Despite the reductions in anesthetic dosage, BIS values remained below the minimum target of 40. Maintenance BIS in this age group was 35.7 (9.6), despite a significantly smaller than anticipated end-tidal sevoflurane concentration. BIS 6 months–3 years: 54.8 (9.1) BIS, 3–18 years: 47.2 (10.1) SP, 0–6 months: 36.2 (11.8) SP, 6 months–3 years: 50 (14.1) SP, 3–18 years: 39.6 (11.5)	BIS: 47
