Abstract:

BACKGROUND: Although some scholars have affirmed the effect and safety of lateral position for percutaneous vertebroplasty. But impact of surgical position on the changes in the vital signs during the operation has not been reported.
OBJECTIVE: To observe the effects of different body position in vital signs and blood oxygen saturation of patients during percutaneous vertebroplasty.
METHODS: Thirty cases of thoracolumbar osteoporotic vertebral compression fractures (OVCF) were divided into two groups randomly: the prone position group (15 cases) and the lateral position group (15 cases), both of them are given local anesthesia for percutaneous vertebroplasty. Record of vital signs and blood oxygen saturation for each patient in the following time points were observed, including supine position before surgery (T1), 5 minutes after body position changing (T2), the process of needle puncturing (T3), the process of injection of bone cement (T4), at the end of bone cement injection (T5), the supine position after surgery for 5 minutes (T6).
RESULTS AND CONCLUSION: In the prone position group, the heart rate and respiratory rate were higher than those of the lateral position group (P < 0.05) in the time points including T1, T2, T3, T4, T5. The artery systolic pressure in the prone position group was lower than that of the lateral position group (P < 0.05) in the time points including T2, T3. The blood oxygen saturation in the prone position patients group was lower than that of the lateral group (P < 0.05) in the T5 time point. The above shows that the lateral position has less effect on the patient’s vital signs and oxygen saturation than the prone position, which is also conducive to improve the tolerance operation of patients during the percutaneous vertebroplasty.
