ABSTRACT
To evaluate the surgical technique and clinical effect of applying Flow-through flap pedicled with superficial palmar branch of radial artery for bridging finger replantation complex defect of soft tissue and vessel. Methods From February, 2013 to March, 2018, 9 cases of severed fingers composited defect of soft tissue and vessel were treated with Flow-through flap pedicled with superficial palmar branch of radial artery.The flap was designed from the proximal end of rasceta and the donor sites were sutured directly. The size of flaps was 3.0 cm ×1.5 cm-4.0 cm×2.2 cm. The superficial branch of the radial artery in the flap was used to bridge the finger artery. And the vein of proximal and distal ends in the finger was bridged by the subcutaneous vein. The proper palmar digi-tal nerve defect was bridged by palm skin graft of median nerve. The appearance, feeling and joint function of fingers was followed-up regularly after operation. Results All transfering flaps survived and all cases were followed-up for 7 to 33 months. The donor sites got primary healing with straight scars. The appearance and texture of the flaps were satisfactory. Two-point discrimination ranged from 8 to 11 mm. The pain sensation, warmth sensation and touch sen-sation of the flaps got better. And the appearance and functions of severed fingers recovered well. Conclusion The Flow-through flap pedicled with superficial palmar branch of radial artery is easy to harvest and anastomose, which is masked and a small incision for the donor site. It is an ideal method for bridging severed fingers and repairing of fin-ger wound.
ABSTRACT
Objective To analyze the hidden blood loss following primary total hip arthroplasty (THA) and put forward corresponding treatment measures.Methods A retrospective study was done on the 138 patients with hip disease managed with THA for the preliminary unilateral replacement from January 2009 to January 2011.There were 48 males and 90 females,at age range of 45-71 years (mean,62 years).The pre-and post-operative blood routine and intra-and post-operative blood loss and transfusion were analyzed and hidden blood loss during peri-operation period was evaluated.Results All the patients were trnsfused with autologous blood intra-operatively.Intra-operative blood loss was (495 ± 105) ml and postoperative drainage volume was ( 121 ±29) ml.In addition,116 patients were given red cell suspension (RCS) and blood plasma to raise the level of hemoglobin and the RCS transfusion volume was (600 ± 225) ml.The total blood loss was (1 521 ±156) ml including hidden blood loss of (822 ±96) ml (57.2％).No obvious differences were observed in the indicators between males and females.Conclusions Hidden blood loss is an important factor that affects the prognosis of the patients treated by THA.In order to secure their safety in perioperative period and benefit their recovery,assessment of the amount of bleeding in THA should fully take the hidden blood loss into consideration and prompt treatment measures should be taken to fully and effectively recover their effective circulation blood volume.
