Ultrasound guided mandibular nerve and cervical plexus nerve block for clinical evaluation of parotid gland operation for postoperative analgesia / 临床麻醉学杂志

ABSTRACT

Objective To evaluate the effect of mandibular nerve and cervical plexus nerve block guided by ultrasound for postoperative analgesia of parotid gland operation.Methods Sixty pa-tients of both sexes (29 males,31 females),of ASA physical status Ⅰ or Ⅱ with parotid gland oper-ation,were randomly divided into two groups (n =30)nerve block group and traditional drug group. All patients received general anaesthesia.In traditional drugs group,according to patient's request, we used analgesic drugs.In nerve block group,after general anaesthesia,we provided mandibular nerve and cervical plexus nerve block guided by ultrasound.Both groups were recorded the amount of analgesic drugs and rest/motor VAS after operation 1st day and 2nd day,the ratio of using analgesic drugs was also recorded at the same time.Results Compared with traditional drugs group,the a-mount of analgesic drugs and rest/motor VAS was decreased in nerve block group on the 1st day after operation.But on the 2nd day after operation,there was no difference between them.The ratio of u-sing analgesic drugs of nerve block group was lower than that of traditional drug group. Conclusion Mandibular nerve and cervical plexus nerve block guided by ultrasound is effective for postoperative analgesia for parotid gland operation.
