Analgesia, Patient-Controlled
Conditions
Brief summary
To explore the effect of different drugs and infusion ways on degree of postoperative comfort.Patients undergoing spinal neoplasm surgery receive different patient controlled analgesia(PCA) drugs postoperatively,one group is sufentanil,the other is hydromorphone. Then each drug group will be divided into two subgroups according to the infusion way,intravenously,subcutaneously. During the patient controlled analgesia period, patients' degree of comfort,pain score,sleep quality, the degree of side reaction will be recorded.
