Objective: To investigate the impact of peer-assisted learning (PAL) in chest tube insertion education on surgical residents. Methods: This study is a quasi-experimental study conducted on thirty general surgeon residents enrolled in the PAL program. They were divided into two learner groups (A and B) based on the period of residency start. Group A and B had six and one months of general surgery residency experience, respectively. All participants received adequate training for chest tube insertion by a recently graduated general surgeon. Chest tubes insertion skill was assessed using the tool for assessing chest tube insertion competency (TACTIC) test. Results: Post-TACTIC test score was significantly higher (p=0.001) than Pre-TACTIC test score in both groups. However, a comparison of mean Pre-TACTIC test scores and mean Post-TACTIC test scores between group A and group B showed that PAL effectiveness in group A was significantly higher (p=0.001) than group B. Conclusion: There was a positive relationship between the PAL program and the improvement of chest tube insertion technical skills in surgical residents. Based on our findings and similar studies, it can be concluded that the PAL program can increase the chest tube insertion skill of surgical residents.

Objectives: To evaluate the short-term outcome of open appendectomy, the rate of negative appendectomy as well as pathology reports after surgery in patients with suspected acute appendicitis.Methods: This was a retrospective cross-sectional study being performed in Nemazee hospital affiliated with Shiraz University of Medical Science during a 2-year period between 2008 and 2010. The medical records of all consecutive patients who underwent open appendectomy in our center due to acute appendicitis were included in the study. The elective and laparoscopic appendectomies were excluded. The demographic information, clinical findings, laboratory investigations and the histopathological examination of the appendix were recorded and reported.Results: A total of 337 patient including 137 (36.4%) females, and 240 (63.6%) males with the mean age of 16.26 ± 9.81 (range 3 to 76) years were stduied. Anorexia (64.7%) and fever (20.7%) were more prevalent symptoms. The mean duration between pain initiation and operation ranged from 0 to 14 days with mean 1.88 ± 1.63 days. Right lower quadrant (RLQ), periumbilical, epigastria, left lower quadrant (LLQ), and Right upper quadrant (RUQ), pain were manifest in 78.8%, 41.6%, 12.2%, 3.2%, and 1.3% of patients, respectively. Pathological evaluation of the appendix showed appendicitis in 70.4% of patients.Conclusion: The higher rate of negative appendectomy accounts for wasteful tapping of medical resources and causing further complication in patients. Therefore it is essential to conduct more accurate studies to detect the root cause of the disease. This would help improve the management of appendicitis which is an emergency condition with high incidence.

Objective: To record and classify mechanisms of injury and injury severity score (ISS) in trauma patients admitted to the largest trauma center in Southern Iran.Methods: This was a prospective cross-sectional study including all the patients who were admitted to Nemazee hospital from 2009 to 2010. We recorded the trauma injury information of 1217 patients who were admitted to of emergency room of the Nemazee hospital during a 13-months period by means of a standard questionnaire. ISS was then obtained for every single patient.Results: The mean age of patients was 26.6 ± 15.1 (range 1–95) years. The commonest type of trauma including 279 cases (22.9%) was car accident and the least resulted from shotgun injuries in 13 (1.1%) patients. The lowest ISS was due to assault multiple blunt traumas and the highest ISS resulted from shotgun injury. The mean ISS was about 6.3 ± 1.8 (range 1-66). Overall, 86 patients had scores above 17 (7.1%). A total of 69 male patients (7.5%) compared to 17 females (5.7%) had severe injury (ISS>17). Trauma injuries were significantly more severe in males compared to females (p=0.014). In the sunny and hot seasons total number of patient was higher. The mean ISS was highest in during spring (p<0.001).Conclusion: In Shiraz, most of the trauma injuries are occurred during summer and hot weather. Men have greater number of injuries and higher ISS compared to women. The lowest ISS was due to assault multiple blunt trauma and the highest ISS was caused by shotgun injury, and car accident was the commonest cause of trauma with head and neck being the most frequent sites in our patients.

Objective: To determine the removal time of the chest tube in ICU trauma patients under positive ventilation pressure (PVP).Methods: This was randomized clinical trial being performed in ICU department of Rajaei trauma hospital from March to December 2011. A total number of 92 trauma patients who were admitted in ICU and were under ventilation and had chest tube were randomly assigned into two groups. In case group, chest tube was clamped after 5–7 days. In the control group, chest tube was retained until the patients were under PVP. The chest tube was removed if there was no air leak or the drainage was less than 300 mL.Results: Complications observed in the case and control groups were 4.4% of 4.3% respectively (p=0.862). Among case group with hemothorax, 6.7% developed complication while this ratio for pneumothorax was 7.1% and zero in those with hemopneumothorax (p=0.561), whereas respective values for the control group were 11.1%, 8.3% and zero (p=0.262). Complications were noticed in 10.5% of those with more than 300 ml of pulmonary drainage. There were no complications in patients without air leak. In mild leak, 4.8% of subjects experienced complication, in moderate leak, no complication occurred and in severe ones, complication was visible in 7.7% of patients (p=0.842).Conclusion: The present study showed that the removal of chest tube in patients under ventilation within 5-7 days after its insertion is safe without any complications.

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.
