Objective To compare the clinical effect of ultrasound and nerve stimulator guidance for interscalene brachial plexus block. Methods Sixty patients scheduled for upper extremity surgery were randomly allocated into two groups to receive either nerve stimulator guidance (group N,30 cases) or ultrasound guidance (group U, 30 cases) for interscalene brachial plexus block. The time for completing the procedure, the onset time of sensory block and motor block, as well as success rate of the procedure were recorded. The requirement for fentanyl during surgery, pain related with procedure and incidence of other complications were also recorded. Results The success rate of the procedure was 100% in both groups.Longer time was needed for completing procedure in group U [(16±7)min] than that in group N [(11±5)min](P＜0.05). The onset time of sensory block was significantly shorter in group U [(13±9)min] than that in group N [(18±7)min] (P ＜ 0.05 ), while the onset time of motor block was similar between the two groups. Twelve patients in group N and 5 patients in group U complained pain related with procedure, which were significantly different (P＜0.01 ). Conclusion Interscalene brachial plexus block with ultrasound guidance has similar clinical effect and success rate compare with nerve stimulator guidance.

BACKGROUND: During conventional treatment for bone tuberculosis, there is a low effective concentration of anti-tuberculosis drugs, and the therapeutic effect is poor. OBJECTIVE:To develop a new biomaterial as a slow-release artificial carrier that can be directly implanted into the surrounding tissue of bone tuberculosis, maintain a certain anti-tuberculosis drug concentration for a long time, thereby playing an effective therapeutic action. METHODS:Rifampicin/polylactic acid/glycolic acid microspheres and isoniazid/polylactic acid/glycolic acid microspheres were prepared using the emulsion-solvent evaporation method. Usingα-cyanoacrylate, a biological adhesive, two kinds of microspheres were processed into a long-term slow-release bicomponent drug carrier. Then, in vitro release characteristics of the dual-drug sustained-release carrier were observed. After that, the dual-drug sustained-release carrier was implanted into rabbit intertrochanteric femur bone defects for observing drug release concentrations, histocompatibility and bone defect healing at different time points after drug delivery carrier implantation. RESULTS AND CONCLUSION:For rifampicin/polylactic acid/glycolic acid microspheres, the mean particle size was (240±13)μm, and the drug loading load rate was (26±1.5)%. For isoniazid/polylactic acid/glycolic acid microspheres, the mean particle size was (250±10)μm, and drug loading rate was (28±1.8)%. The in vitro cumulative release rate could reach 80%for rifampicin and 90%for isoniazid at day 90. The in vivo released concentration of rifampicin and isoniazid within 90 days was (0.5±0.4) and (0.6±0.3)μg/g, respectively. There were a smal amount of infiltrated neutrophils between the fascia and muscle fibers after the drug delivery carrier was implanted, and the amount of neutrophils in the muscle were reduced significantly at day 59. X-ray plain film showed that bone defects decreased obviously in size. These findings indicate that this dual-drug sustained-release carrier can maintain a certain anti-tuberculosis drug concentration in the surrounding tissues of bone tuberculosis, which is expected to provide a new type of dual-drug delivery carrier in the surgical treatment of bone tuberculosis.

Objective To review the clinical features and early management of combined thorcoabdominal injury(CTI),to decrease the mortality rate.Methods A retrospective study was carried out in 63 cases of CTI treated surgically from May 1990 to May 2007.There were 34 cases with blunt injuries and 29 cases with penetrating injuries.Forty-seven patients had rapture of left diaphragm,9 cases had rupthure of right diaphragm,7 cases had rupture of both diaphragms,24 cases were combined with traumatic diaphragmatic hernia,63 cases were combined with hemopneumothorax,and 60 cases were combined with shock.Forty-one cases were diagnosed correctly before surgery.Sixty-three cases were treated by surgery,among them,surgery was performed through left thoracotomy in 18 cases,through a right thoracotomy in 2 cases,through bilateral thoracotomy in 5 cases,through thoraco-abdominal incision in 2 cases,and through the abdominal route in 32 cases.Results Fifty-six cases were cured,and 7 cases(11.1 %) died.The main cause of death was hemorrhagic shock.Conclusions CTI has high mortality rate,and the most frequent cause of mortality is hemorrhagic shock.The operative approach is based on the individual injury condition.Early diagnosis and timely surgical intervention is the key to improving the cure rate and reducing mortality in severe CTI.
