ABSTRACT
To evaluate the efficacy of modified perihepatic packing [MPHP] in reducing the rate of re-bleeding rate after packing removal. 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. 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]. 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
ABSTRACT
Objective: To explain an important aspect of violence, the Spatiotemporal pattern of trauma in victims of violence visited in emergency room of Rajaei hospital, Shiraz, Iran
Methods: This cross-sectional prospective study comprised 109 randomly selected victims of violence visited in emergency room of Rajaei hospital, a tertiary referral hospital affiliated to Shiraz University of Medical Sciences in winter 2013. We recorded the demographic information as well as data regarding the type and time of the injuries. The data collected for each victim was then entered in a data gathering form
Results: The study included 88% males with mean age 27.8 +/- 8.8 years, which encompassed more tharf| 60% young adults. Our study showed a temporal pattern with triple peaks. Moreover, 64% of assault trauma occurred at night. Furthermore, our study showed the majority of our patients suffered from stab wounds and about 57% of patients studied lacked high school diploma. Moreover it was revealed that violence was more common in downtown Shiraz, especially in the Fifth city district with simultaneous presence of many riskr factors for violence
Conclusion: The result of this study showed that age, gender, educational status and temporal peak of violence were shown to be similar to other investigations conducted in other countries. Despite these similarities, stabbing were more prevalent in our study. Additionally, the Fifth city district of Shiraz seems to be the main city district where preventive intervention is needed to reduce violence- related injuries
