Abstract:

Objective

To evaluate the analgesic effect and safety of preemptive analgesia(PA) model in the treatment of senile osteoporosis vertebra compressed fracture(OVCF) with percutaneous kyphoplasty(PKP).

Methods

A total of 84 patients who conform to the inclusion criteria and were admitted to First Affiliated Hospital of HeBei North University from January 2018 to December 2019 were selected and randomly divided into the PA group and the control group accerding to the random toble method. Both of which were treated with PKP, the pathologic vertebra was injected into bone cement, after via percutaneous puncture and the interventional balloon dilation. The PA group was intramuscular injected with 10 mg Dezocine injection 15 min before the operation, while the control group was not given special treatment before the operation. The visual analogue scale(VAS) score of 4 time points, before operation (T1), trocar puncture (T2), bone cement injection (T3), and 24 h after operation (T4) were recorded in the 2 groups. Recorded the dosage of anesthetics used in the two groups during the operation, and recorded the changes in heart rate and blood pressure of patients at T1, T2 and T3 time points. Adverse drug reactions from T1 time point to T4 time after surgery were recorded. Patients′ satisfaction with the effect of intraoperative pain control were recorded, too. The data was analyzed by t test and chi-square test.

Results

The VAS scores of the two groups at T1 time point were (6.9±0.3), (6.8±0.4) points, and the difference was not statistically significant (t=1.36, P=0.17); the VAS scores of the two groups at T4 time point were (2.2±0.3), (2.4±0.2) points, the difference was not statistically significant (t=1.98, P=0.21); the VAS scores of the two groups at T2 time point were (2.5±0.8), (3.7±0.9) points, the difference was statistically significant (t=3.23, P<0.05); the VAS scores of the two groups at T3 time point were (2.4±0.6), (3.6±0.6) points, the difference was statistically significant (t=3.86, P<0.05). Intraoperative anesthetic dose of PA group(9.1±1.1)mL was significantly lower than that in the control group[(16.6±1.4) mL] (t=4.47, P<0.05). There was no statistically significant difference in heart rate [(92±8), (94±9) times/min] and blood pressure[(1 528/907), (1 559/918) mmHg(1 mmHg=0.133 kPa)] between the two groups at T1 time point (with P values above 0.05), and there were statistically significant differences at T2 and T3 time point (with P values below 0.05). There was no difference in the adverse drug reactions between the two groups from T1 time point to T4 time after surgery (P>0.05). Patients′ satisfaction with the effect of intraoperative pain control was significantly higher in the PA group than in the control group with a difference (χ2=5.48, P<0.05).

Conclusion

It is safe and feasible to perform PA during the operation of PKP in patients with OVCF with good analgesic effect and high patient satisfaction.
