Objective To investigate the clinical application a small dose of ropivacaine in elderly patients undergoing transurethral resection of prostate (TURP).Methods 84 elderly patients with benign prostatic hyperplasia treated by TURP were randomly divided into the control group and the observation group with 42 cases.The control group was given routine dose of ropivacaine for epidural anesthesia,while the observation group was treated with a small dose of ropivacaine for combined spinal-epidural anesthesia.The anesthetic effect,blood flow dynamic changes and adverse reactions were compared between two groups.Results The highest sensory block level of the two groups was no significant difference (t =1.08,P ＞ 0.05).The highest block time of the observation group was shorter than the control group,there were statistical different significantly between the two groups (t =4.21,P ＜ 0.05).The anesthetic effect excellent rate was 100％ in the observation group and the anesthetic effect excellent rate was 88％ in the control group.It was higher than control group,there were statistical different significantly between the two groups (x2 =5.31,P ＜ 0.05).All indicators were statistical different significantly between the two groups except blood pressure differences.The hypotension and the overall incidence of adverse reactions in the control group were higher than the observation group,there were statistical different significantly between the two groups (x2 =4.09,12.81,all P ＜0.05).Conclusion It has a good anesthetic effect,stable hemodynamics,adverse reactions are mild,motor block is light wait for a characteristic by a small dose ropivacaine combined spinal-epidural anesthesia for elderly patients with TURP.It is worthy to recommend its clinical use.

Objective To study the application of nerve block scalp combined with sevoflurane in children drilling drainage oper-ation .Methods 40 children cases undergoing drilling drainage were selected and randomly divided into the scalp nerve block com-bined sevoflurane group(A ,n=20) and the sevoflurane intravenous inhalational combined anesthesia (B ,n= 20) .The changes of HR and MAP before before induction and at 5 min after induction ,skin incision ,15 min after operation beginning ,operation end , postoperative 30 ,120 min were observed and recorded .The awaking time ,occurrence rate of postoperative nausea and vomiting ,in-cidence rate of postoperative dysphoria and fentanyl dosage were compared between the two groups .Results HR ,MAP at skin in-cision ,15 min after operation beginning ,operation end ,postoperative 30 ,120 min in the group B were significantly increased than before operation(P<0 .05);the awaking time in the group A was significantly shortened compared with the group B (P<0 .05) , the fentanyl dosage was significantly reduced (P<0 .05);in the group B ,crying and screaming appeared in 16 cases ,dysphoria oc-curred in 14 cases ,the incidence rate was significantly higher than that in the group A (P<0 .05) .Conclusion Compared with sim-ple sevoflurane intravenous inhalational combined anesthesia ,sevoflurane combined with scalp nerve block used in children drilling drainage operation has rapid induction and rapid awaking ,stable vital signs ,fewer adverse reactions ,small fentanyl dosage and bet-ter anesthetic and postoperative analgesic effects ,which is safe ,feasible ,simple and effective .
