Apllication of scalp nerve block combined with sevoflurane in children drilling and drainage operation / 重庆医学

ABSTRACT

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 .
