Objective To investigate the sedation values of dexmedetomidine combined with midazolam in appendectomy.Methods 90 patients with acute appendicitis were studied prospectively.According to the principle of completely random digital table,all patients were randomly signed into the dexmedetomidine combined with midazolam group,single midazolam group or single dexmedetomidine group.The hemodynamic changes in the three groups were compared.Results There were no significant differences in the three groups in heart rate and mean arterial pressure at t0 (P >0.05).When compared with the single midazolam group or dexmedetomidine group,patients in dexmedeto-midine group got a significant reduction in heart rate at t1 [(79.73 ±10.36)beat/min vs.(93.30 ±19.32)beat/min and (90.85 ±18.23 )beat/min,F =5.796,P =0.004];at t3 [(79.51 ±11.21 )beat/min vs.(87.53 ± 18.35)beat/min and (95.03 ±14.64)beat/min,F =8.006,P =0.001];and at t5 [(79.73 ±12.24)beat/min vs. (91.80 ±17.71)beat/min and (89.62 ±14.26)beat/min,F =5.584,P =0.005];a reduction in heart rate at t2 and t4,though there was no statistical difference (P >0.05);a significant reduction in mean arterial pressure at t1, t2,t3,t4 and t5 (F =8.444,6.591,8.165,17.121 and 6.977,P =0.000,0.002,0.001,0.000 and 6.977);a sig-nificant reduction in visual analogue scales [(3.40 ±1.28 )points vs.(4.50 ±1.81 )points and (4.37 ± 1.71)points,F =4.131,P <0.05 ];a significant reduction in operation duration [(111.17 ±15.77 )min vs. (129.33 ±13.98)min and (132.50 ±14.67)min,F =0.000,P <0.05];and a significant reduction in bleeding vol-ume [(202.47 ±61.07 )mL vs.(246.87 ±52.06 )mL and (241.93 ±58.71 )mL,F =0.006,P <0.05 ]. Conclusion Dexmedetomidine combined with midazolam contributed to maintaining the hemodynamic stable and reducing the operation duration,intra -operation bleeding volume and visual analogue scales.

The arteries of the palmar part of the hand were examined in 50 hands of adult under the operating microscope.The arteries of the hand are arranged at three main levels: the superficial palmar arteries, the deep palmar arteries and the dorsal network. The arterial anastomoses between the levels may be divided into 2 groups: the marginal and the central anastomoses, the former which is situated at the radial and ulnar borders of the palm can be subdivided into superficial and deep groups, the latter is located in the central part of the palm including the direct and indirect anastomostic branches, the proximal and distal perforating branches, and the intermetacarpal perforating branches. The deep arch and its branches, as the center in the total arterial architecture of the palmar part of the hand, closely links with the arteries of the superficial and dorsal ones, playing an important role in regulating the collateral circulation of the hand.The flow formula of the Poiseuille's law indicates that the significant correlation exists between the arterial diameter and the blood flow. For the variety of diameter of each portion of the anastomostic branches, we inferred that the main source of blood flow in the superficial arteries is the ulnar artery and in the deep is the radial artery. The blood within the marginal anastomoses flows from palmar to dorsal, the central mainly from the deep arch and its branches.The dominant parts of the collateral circulation of the hand were found, that is, the deep arch dominantes over the superficial arch and the dorsal network, the central anastomosis over the marginal, the deep branches of the marginal over the superficial branches.The arrangement of the digital arteries has been discussed.

BACKGROUND:Extraction of a wel fixed cementless femoral stem or a cemented stem is difficult during revision of total hip arthroplasty. The extended trochanteric osteotomy provides excellent methods, and combining with long-stem cementless prosthesis can better reduce postoperative complications.
OBJECTIVE:To retrospectively analyze the recent clinical curative effect after extended trochanteric osteotomy combined with long-stem cementless prosthesis in hip revision.
METHODA total of 25 patients undergoing hip revision were selected from the Department of Osteoarthrosis, Pingdingshan First People’s Hospital, China from May 2008 to May 2013. Of them, 17 patients were subjected to the extended trochanteric osteotomy combined with single-incision and double-approaches. The femurs were reconstructed with long-stem cementless prosthesis. Al patients were fol owed-up for 12 to 60 months. Pre-operative and post-operative Harris hip scores, the post-operative complications, the bone cutting length, the length of stem in contact with cortical bone, the length of the end of bone cutting to the end of the prosthesis were recorded.
RESULTS AND CONCLUSION:17 patients were fol owed-up. The mean length of bone was 17 cm (15-23 cm). The mean length of stem in contact with cortical bone was 6.4 cm (4-11 cm). The mean length of the end of bone to the end of the prosthesis was 11.5 cm (8-18.5 cm). After fol ow-up, the mean Harris hip scores were improved from (39.0 ± 13.6) scores preoperatively to (75.0 ± 14.9) scores postoperatively (P<0.01). Subsidence occurred in two hips. The cutting sites of 17 cases of extended trochanteric osteotomy were fixed wel . These data suggested that the operation through single-incision and double-approach to the hip, while preserving the attachment of the external rotators and posterior capsule, wil strength rear hip stability and prevent postoperative dislocations. Recent effects were satisfactory, but the long-term outcomes should be further investigated.
