Objective To evaluate the anesthetic effect and safety of ropivacaine combined with lidocaine caudal block in the treatment of pediatric laparoscopic hernia surgery.Methods A total of 70 cases with pediatric hernia surgery in Ningbo Women and Children’s Hospital from May 2014 to October 2015 in this study were divided into control group and experimental group with 35 cases in each group.The patients in the both groups were given routine examination, preoperative anesthesia induction, adopted 7 scalp injection needles to prick into the hiatus sacralis,patients in control group were treated by 1% lidocaine hydrochloride injection mixed liquid 1 mL/kg;patients in the experimental group were treated by 0.25%lidocaine hydrochloride injection and 0.25% ropivacaine hydrochloric injection mixed liquid 1 mL/kg; pediatric hernia surgery, intraoperative continuous pumped into propofol injection 4-6 mL/kg and maintain the mask to the oxygen.The visual analog pain scored( VAS) , visual satisfaction scored ( VSS) and adverse reactions were compared at the end of operation, after operation 0 h,0.5 h,1 h,2 h,4 h,8 h and 24 h.Results The sensory and motor block effective time in the experimental group were later than the control group, the sensory and motor block duration time were shorter than the control group (P<0.05).VAS score of the experimental group was significant lower than control group after operation 2 h ( P<0.05 ) . After operation, postoperative 0.5 h, postoperative 1 h, the VSS score of the experimental group was significant lower than control group ( P<0.05 ) .Lower limbs numbness discomfort duration time of the experimental group was significant lower than control group after operation ( P<0.05 ) . Postoperative agitation rate of the experimental group 8.57% was significant lower than the control group 34.29% (P<0.05).The incidence of adverse reactions of experimental group 5.71% was significant lower than the control group 25.71% ( P<0.05 ) .Conclusion Ropivacaine combined with lidocaine caudal block in the treatment of pediatric hernia surgery has the remarkable effect, with high safety.

Objective To investigate effect of different doses of propofol infusion on serum lipid metabolism and pulmonary function in patients with cervical cancer operation.Methods 120 patients with cervical cancer were randomly divided into A, B, C three groups, 40 cases in each group, were treated with laparoscopic cervical cancer radical operation, the 4 mg/(kg· h), 6 mg/(kg· h), 8 mg/(kg· h), and the pulmonary function and lipid profiles were detected.Results Compared with the B and C groups, the recovery time and the the awake time of the patients in B ,C group was shorter (P<0.05).The recovery time and the the awake time of the patients in A group had not significantly different.Compared with before operation, TG, TC and LDL levels were elevated, HDL decreased in theree groups after the operation(P<0.05);compared with the A and B groups, the levels of TC, LDL, TG and were higher, the level of HDL were lower (P<0.05),there were no significant differences in level of TC, HDL, TG and LDL between group A and group B;there was no significant difference between P(A-a) O2 and RI among three groups before surgery, P(A-a) O2 and RI levels were elevated in the three groups after surgery(P<0.05), compared with the A and B groups, P(A-a)O2 and RI levels in group C were lower(P<0.05), there was no significant difference in P(A-a)O2 and RI between group A and group B.Conclusion 4 mg/(kg· h)of propofol can significantly shorten the recovery time and awake time, improve the level of lipid metabolism and pulmonary function.
