Clinical observation on point-injection anesthesia applied in 61 thyroid sugery cases
2009
Objective To evaluate the therapeutic effect of point-injection anesthesia for thyroid operation. Methods 123 patients with thyroid diseases requiring treatment by surgery were randomly allocated to two groups: the experimental group included 61 cases who were anesthetized by point-injection; the control group included 62 cases who were anesthetized by cervial plexum block. Differences in onset time of anesthesia, VRS evaluated 30 minutes after injection, the SBP, DBP, HR before opreration, the SBP, DBP, HR at the beginning of the operation, the SBP, DBP, HR at the end of the operation, the incidence of nausea and vomiting during and post operation, the incidence of the complications(diaphragmatic paralysis, recurrent laryngeal nerve paralysis and Hornor syndrome) post operation were assessed between two groups. Results For the onset time of anesthesia, VRS evaluated 30 minutes after injection and the SBP, DBP, HR before operation, the differences were not statistically significant between the two groups (P=0.64, 0.87, 0.65, 0.48, 0.47 respectively).At the beginning and end of the operation, the SBP, DBP, HR decreased in the experimental group compared with the control (P <0.01). For the incidence of nausea and vomiting during and post operation, no significance was observed between the two groups(P=0.26). The incidence of diaphragmatic paralysis, recurrent laryngeal nerve paralysis and Hornor syndrome post operation decreased in the experimental group compared with the control. Conclusion Point-injection anesthesia, the complications incidence of which is lower, is as effective as eervial plexum block, and it is suitable for the grass-roots hospitals.
