Application of ultrasound-guided caudal epidural blockade in pediatric concealed penis surgery
Objective To investigate the application value of ultrasound-guided dexmedetomidine caudal epidural blockade in pediatric concealed penis surgery.Methods 90 children(ASA gradeⅠ-Ⅱ,aged 6-12 years)who underwent penile straightening surgery in Lu'an Hospital Affiliated to Anhui Medical University from August 2021 to December 2022 were ran-domly divided into three groups:control group(group A),ropivacaine caudal epidural blockade group(group B)and dexme-detomidine combined with caudal block group(group C),with 30 cases in each group.Laryngeal mask general anesthesia was used,and children were sent to anesthesia resuscitation room after surgery.Heart rate(HR),mean arterial pressure(MAP),FLACC score,and the incidence of emergence agitation(EA)before induction(T1),5 minutes after sacral block(T2),at the time of skin incision(T3),at the time of finishing suture(T4),and at the time of removing laryngeal mask(T5)as well as adverse reactions such as nausea and vomiting,respiratory depression and delayed recovery were recorded in children.Re-sults MAP in the group C was significantly lower than those in the group A and the group B at T5,and HR in the group C was significantly decreased at each time point(P<0.05).24 h after surgery,the FLACC scores of the group C were lower than those of the group A at all time points(P<0.05),and were also lower than those of the group B at 8-24 h after surgery(P<0.05).At the same time,the usage rate of acetaminophen in the group C was significantly lower than that in the group A(P<0.05).The incidence of EA in the group C was significantly lower than that in the group A(P<0.05).No obvious adverse re-actions occurred in the three groups.Conclusion Ultrasound-guided dexmedetomidine caudal epidural blockade can ensure adequate sedation and analgesia in children with pediatric concealed penis surgery,reduce the use of analgesic drugs,and low-er the incidence of EA.
