A modified working tube can reduce bone cement Ieakage in the treatment of osteoporotic vertebraI compression fracture / 中国组织工程研究

BACKGROUND: Vertebroplasty is an effective treatment for osteoporotic vertebral compression fractures (OVCF), but it is nagged by bone cement leakage. OBJECTIVE: To summarize the clinical outcome of modified self-making working tube in percutaneous vertebroplasty (PVP) for treatment of thoracolumbar OVCF. METHODS: Modified PVP working tube was designed to have a lateral gap at the sleeve tail, which could control the cement diffuse direction though rotating the working tube. Totally 121 thoracolumbar OVCF patients were enrolled, including 49 males and 72 females, aged 62-90 years, and then divided into two groups: 59 patients were treated with modified PVP in test group, and the other 62 patients experienced conventional PVP in control group. In the test group, a lateral gap instead of the conventional gap at the sleeve tail was made to control the direction of bone cement injection by rotating the sleeve. The visual analogue scale scores were compared before and after operation; radiographic examination was performed to detect bone cement leakage at 1 day postoperatively. RESULTS AND CONCLUSION: There were significant differences between the preoperative and postoperative visual analogue scale scores in the two groups (P < 0.05), but there was no significant difference between the two groups. There were 3 cases of bone cement leakage in the test group and 10 cases of bone cement leakage in the control group. Modified PVP working tube had significant lower rate of bone cement leakage than traditional PVP(14.9% vs.4.6%,P<0.05).Therefore,the modified PVP working tube is an effective tool to decrease the incidence of bone cement leakage in the treatment of thoracolumbar OVCF.

Effect of electroacupuncture combined epidural anesthesia on plasma concentration of IL-1beta in patients undergoing gynecological surgery / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To study the effect of electroacupuncture (EA) combined epidural anesthesia on plasma concentration of IL-1beta in patients undergoing gynecological surgery.</p><p><b>METHODS</b>Forty patients who were scheduled to receive gynecological operation under epidural anesthesia were randomly assigned to the epidural anesthesia group (Group A, 20 cases) and the epidural combined EA group (Group B, 20 cases). All patients in the two groups received epidural anesthesia. Continuous EA at Zusanli (ST36) and Sanyinjiao (SP6) with the frequency of 30 -100 Hz was applied in those in Group B. The peri-operative hemodynamic changes, visual analog scale (VAS), and the plasma concentration of IL-1 3 were observed.</p><p><b>RESULTS</b>There was no statistical difference in peri-operative hemodynamic changes between the two groups (P >0.05). Compared with Group A, the VAS was lower in Group B at post-operative 8, 24, and 48 h, respectively (P <0.05), and the plasma concentration of IL-1beta was also lower in Group B at post-operative 4 h, 24 h, and 3 days (P <0. 05).</p><p><b>CONCLUSION</b>Acupuncture could ease postoperative pain and reduce the plasma concentration of IL-1beta.</p>

Effect of acupuncture-assisted anesthesia on stress response during laparoscopic cholecystectomy in aged patients / 中国针灸

<p><b>OBJECTIVE</b>To compare the difference between transcutaneous electrical acupoint stimulation (TEAS) assisted general anesthesia and simple general anesthesia on stress response during laparoscopic cholecystectomy (LC) in aged patients.</p><p><b>METHODS</b>Forty patients underwent LC were randomly divided into a TENS assisted general anesthesia group (group T) and a general anesthesia group (group G), 20 cases in each group. After TEAS for 30 min, general anesthesia was applied in group T, and TEAS was continued until LC over. In group G, only routine general anesthesia was given. Mean arterial pressure (MAP), heart rate (HR), saturation of blood oxygen (SpO2), PetCO2, and the contents of plasma endothelin (ET), cortisol (Cor) were measured before anesthesia (T0) and after intubation cannula 5 min (T1), after pneumoperitoneum 5 min (T2) and 15 min (T3), and LC over (T4). The rate of hypotension and hypertension were observed during preoperative period.</p><p><b>RESULTS</b>The hemodynamics indices decreased in group G at T1 than before. The reductions of MAP and HR in group G were larger than those in group T at T1 (P < 0.05). After pneumoperitoneum, the hemodynamics indices and serum ET and Cor have no differences in group T as compared with before (all P > 0.05), but they were all increased more significantly in group G than before, and with significant differences between group G and group T at each time point (P < 0.05, P < 0.01).</p><p><b>CONCLUSION</b>Acupuncture-assisted anesthesia profit to maintain the hemodynamic stable and reduce the stress response during LC in aged patients.</p>

Effect of combined electroacupuncture and epidural anesthesia in gynecological operation evaluated by bispectral index / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To evaluate the effect of combined electroacupuncture (EA) and epidural anesthesia in gynecological operation by bispectral index (BIS).</p><p><b>METHODS</b>Sixty patients of ASA grade I-II, 20-60 years old, being scheduled to receive gynecological operation with epidural anesthesia were randomly assigned to 3 groups equally. Group A was anesthetized with epidural infusion of midazolam in dosage of 0.04 mg/kg, Group B with continuous EA in 30-100 Hz on Zusanli (ST36) and Sanyinjiao (SP6) acupoints, and Group C with both epidural infusion and EA same as those applied in Groups A and B. BIS, blood pressure (BP), heart rate (HR), and blood oxygen saturation (SPO2) were monitored during peri-operative stage, and the post-operation visual analogue scores (VAS) was measured as well.</p><p><b>RESULTS</b>BIS decreased after operation in all groups (P < 0.05), the highest value was shown in Group B (P < 0.05) and the lowest was seen in group C at time of skin incising; while at time of gauze plugging, it was higher in Group B than in other two groups (P < 0.05). Besides, VAS in Group A at 8 h and 24 h after operation was higher than that in the other two groups respectively (P < 0.05).</p><p><b>CONCLUSION</b>BIS can be taken as an index for objectively evaluating the effect of combined EA and epidural anesthesia in gynecological operation. EA anesthesia has certain analgesic and sedative effects, could effectively release postoperative pain.</p>
