ABSTRACT
Objective To investigate the effects of enhanced recovery after surgery (ERAS) pathway on early cognitive function of post-hepatectomy patients after hepatectomy.Methods Ninety-six patients undergoing elective hepatectomy for liver cancer were randomly assigned into two groups:group ERAS,n =48 and group C,n =48.patients in group ERAS accepted perioperative and anaes-thetic optimization of enhanced recovery after surgery pathway,and patients in group C received peri-operative and anaesthetic management of normal surgery concept.The mini-mental state examination (MMSE)was used to test the cognitive function of the patients one day before operation (T0 ),one day after operation (T4 ),three days after operation (T5 )and seven days after operation (T6 ),and the blood levels of S100βprotein,neuron-specific enolase(NSE),IL-1β,IL-6,and TNF-α were de-tected at T0 ,30 minutes after operation (T1 ),6 hours after operation (T2 ),12 hours after operation (T3 )and T4 .Results Compared with group C,MMSE scores in group ERAS were increased at T4 ,T5 , the blood levels of S100βprotein,IL-1βand IL-6 in group ERAS were decreased at T1 ,T2 ,the blood levels of NSE in group ERAS were decreased at T2 ,T3 ,the blood levels of TNF-αin group ERAS were decreased at T1-T3 ;Compared with the baseline value at T0 ,MMSE scores were decreased at T4 ,T5 in group C and decreased at T4 in group ERAS,the blood levels of S100 βprotein in two groups were increased at T1-T3 , the blood levels of NSE in two groups were increased at T2-T4 ,the blood levels of IL-1β,IL-6,and TNF-αin two groups were increased at T1-T4 ;and the postoperative length of stay in group ERAS were decreased. Conclusion Enhanced recovery after surgery pathway is helpful in improving early postoperative cognitive function of patients after hepatectomy,and the mechanism may be related to decreased the blood levels of S100βprotein,NSE,IL-1β,IL-6 and TNF-α.
