Objective To evaluate the effection of limited fluid resuscitation in early treatment of traumatic hemorrhag-ic shock patients. Methods A total of 80 cases with traumatic hemorrhagic shock patients were randomly divided into observation group and control group by tossing a coin from January 2012 to December 2013, with each 40 cases, the observation group was given the limited fluid resuscitation therapy, the control group was given conventional fluid re-suscitation therapy. The officacy of two groups was analyzed. Results The infusion volume, hemoglobin concentration,mean arterial blood pressure, and prothrombin time of the observation group were significantly lower than those in the control group,with statistically significant difference(P<0.05). The TNF-α,IL-2 of the observation group were signifi-cantly lower than those in the control grous after resuscitation, with statistically significant differences (P<0.05). The fatality rate and the complication rate of the observation group were significantly lower than those in the control group,with statistically significant differences(P<0.05). Conclusion Limited fluid resuscitation on traumatic hemorrhagic shock patients early has good clinical effect, can ensure the blood supply to the important organs, improve the cure rate,improve prognosis.

OBJECTIVETo improve the treatment for severe open tibia-fibular fracture.

METHODSFrom 1994 to 2000, 146 patients with severe open tibia-fibular fracture were treated. According to Gustilo classification, all patients were of type III. Among them, 96 patients belonged to III A, 36 III B, and 18 III C. One hundred and eight patients were male and 38 female, aged from 11 to 68 years, with an average of 31. All patients were treated with unilateral external fixator combined with simple internal fixation (general screw or Kirschner wire). Thirty patients were treated with secondary flap operation. Among them, 19 patients received pedicle gastrocnemius muscle flaps, 9 free vastus lateralis muscle flaps, and 2 free latissimus dorsi muscle flaps.

RESULTSThree patients of type IIIB were subjected to amputation because of advanced age and associated cerebral or thoraco-abdominal injury. Five patients of type III C had amputation because of insufficient postoperative blood supply and necrosis. The rupture of other 138 patients was well reduced, and firmly fixed. They were followed up for 6 months-6 years, with an average of 2.5 years. The average time of fracture-union was 27 weeks, and the average time for removal of fixtors was 28 weeks. The motion of knee joint ranged from 0 to 120 degree in 110 patients; from 0 to 100 degrees in 25, and from 0 to 90 degrees. The motion of ankle joint was approximately normal.

CONCLUSIONSFor patients with severe open tibia-fibular fracture, comprehensive analysis should be made for preservation of the wounded limb or amputation as for elderly patients with vessel-nerve injury or with cerebral- thoracoabdominal injury, emergency amputation should be done. Unilateral external fixator combined with simple internal fixation (general screw or Kirschner wire) for severe open tibia-fibular fracture is advantageous for a simple and reliable fixation. It is less traumatic.

Objective To discuss the safety and the application of the self-designed multifunctional inflatable pelvis and hip-joint fixator (MIPHF) in damage control in pelvic fracture patients.Methods The MIPHF was subjected to pressure test and quality inspection.From September 2016 to June 2017,61 pelvic-fracture patients were treated with our self-designed MIPHF as pre-hospital first-aid care according to the concept of damage control orthopedics (DCO) (MIPHF group).The control group consisted of 69 pelvic-fracture patients who had not received pre-hospital first-aid care with the self-designed MIPHF from December 2015 to August 2016.There were no statistically significant differences between the two groups in gender,age,types of pelvic fracture,and preoperative injure severity score (ISS).The study compared the two groups for the case fatality rate,volume of blood transfused during surgeries,early complication rates,fracture reduction (Matta standards),and long-term efficacy (Cole scores).Results The pressure test showed that the MIPHF had a good fixation effect on the pelvis.And the quality inspection showed that the material used for the MIPHF was in line with national standards and the safety was guaranteed.The MIPHF group had 1 death (1.6％) and the control group had 8 deaths (11.6％),which was a significant difference (x2=4.979,P=0.026).All survival patients in both groups were followed up.The MIPHF group (61 cases) received 3.0 to 18.0 months follow-up,with an average of 9.0 months.And the control group (69 cases) had 18.0 to 30.0 months follow-up,with an average of 21.9 months.In the MIPHF group,23 cases were treated conservatively,and 37 cases were treated with surgery.Among them,3 cases were fixed with external fixator,20 cases with anterior open reduction and internal fixation,9 cases with posterior open reduction and internal fixation,and 5 cases with combined anterior and posterior fixation.The timing of surgery was 1 to 20 days after injury,with an average of 4.1 days.The volume of blood transfused in the MIPHF group during surgery was 200 to 1500 ml,with an average of 628.6 ml.In the control group,27 patients were treated conservatively,and 42 patients were treated with surgery.Among them,2 cases were fixed with external fixator,24 cases with anterior open reduction and internal fixation,10 cases with posterior open reduction and internal fixation,and 6 cases with combined anterior and posterior fixation.The timing of surgery was 1 to 15 days after injury,with an average of 3.l days.The volume of blood transfused in the control group during surgery was 200 to 4000 ml,with an average of 1 707.1 ml.There was a significant difference between the two groups in intraoperative blood transfusion(Z=-2.330,P=0.020).The MIPHF group had 10 (16.4％) cases of early serious complications and the control group had 22 (31.9％) cases,which had a significant difference (x2=4.187,P=0.041).According to the criteria proposed by Matta et al.,the good rate of results for treating fractures was 82.0％ in the MIPHF group and 60.9％ in the control group,which got a significant difference (x2=6.967,P=0.008).The MIPHF group and the control group also differed significantly in their mean long-term Cole scores (27.2±4.0 versus 25.1 ±5.6,t=2.457,P=0.015).Conclusion MIPHF,which reflects the DCO concept,may be recommended as pre-hospital first-aid care for patients with pelvic fracture because it can lessen bleeding and prevent secondary pelvic injury,thus reduce case fatality rate and the incidence of complications.It can also improve the success rate of treating pelvic fracture,which will positively affect long-term outcomes.
