Objective: To evaluate the efficacy of modified perihepatic packing (MPHP) in reducing the rate of re-bleeding rate after packing removal.Methods: This was an experimental study being performed in Shiraz animal laboratory. High grade liver parenchymal injury was induced in 30 transgenic Australian rabbits which were then divided into two groups. Group A (control) included 14 and group B (experimental) comprised 16 rabbits. The animals in group A underwent standard perihepatic packing (SPHP) and those in group B were subjected to MPHP. Re-bleeding was assessed and compared between the two groups, after removal of perihepatic packings.Results: There was no significant difference between two study groups regarding baseline and perioperative characteristics. Rabbits in group A had significantly lower rate of postoperative re-bleeding compared to those in group A (57.1% vs. 12.5%; p=0.019). The mean bleeding volume was also significantly lower in group B compared to group A (76.88 ± 22.12 vs. 98.93 ± 33.8 mL; p<001). Although the survival rate was higher in group A compared to group B (93.8% vs. 78.6%) but the difference was not statistically significant (p=0.315).Conclusion: MPHP is a simple and safe procedure for surgical management of high grade liver parenchymal injury concomitant with severe loss of glisson’s capsule. This procedure significantly decreases re-bleeding after packing removal in comparison with SPHP.

Objective: To evaluate the predictive value of some biochemical markers in the outcome of extremity vascular trauma.Methods: This study comprised 30 patients with traumatic arterial injury and acute limb ischemia referred to Namazi hospital affiliated with Shiraz University of Medical Ssciences, over a period of 8 months, from Sep 2009 to Jul 2010. Venous blood samples were drawn from distal ischemic limb to determine pH, HCO3 - , PCO2 , PO2 , Na+, and K+ before definitive surgical intervention. Comparable samples were also obtained from veins of non- ischemic upper extremities. The biochemical assays were compared after monitoring the revasculurized limbs and evaluation of viability during a period of 7 days.Results: The mean age of the patients was 28.3 ± 7.8 (range: 18–56) years. Two (6.6%) patients underwent amputation because of developing irreversible limb ischemia after vascular reconstruction. Both patients had blunt traumatic knee injury accompanied by nerve, vein and soft tissue damage. The statistical analysis showed correlations between parameters, except for Na+, of local (ischemic limb) and systemic samples. In this context, the highest correlation was observed in regard to HCO3 - .Conclusion: The correlation was most pronounced with respect to HCO3 - . Ischemic limbs exhibited reduction in pH and PO2 but, PCO2 and K increased after ischemia of injured limbs. PO2 reflects tissue perfusion and is of value in predicting the outcome. We believe that blunt trauma and associated nerve, vein and soft tissue injuries pose negative prognostic effects on limb survival postoperatively.
