Influence of dressing on the rate of wound infection in clean surgeries

Background&Objective: The ways of prevention of wound infections are too much, and some references mentioned that one of those ways is dressing. Dressing can cause a sort of spiritual transquility for patients, too. In the other side, doing it causes some kinds of limitations such as preventing of taking a bath or spending expenses. So, we decided to consider the influence of continuation of dressing, on the rate of wound infection, after first 48 hours post operation. Materials&Methods: In this research, we studied on 150 patients who were under the same surgeries, So that in the half of them, after 48 hours dressing were removed, and in the half remaining, dressing were changed daily for one week. In both groups, in the third, seventh and thirtieth day after surgery were inspected and examined by surgeon, in the case for having or absence of symptoms and signs of infection. In subgrouping patients we considered some factors include age, sex, type of operation and predisposing diseases. The 30 th day post operation was the end of our study and information analyzed in the computer with SPSS software. Results: The average age in the group of without dressing was 35.12±20.19 and in the group with full dressing was 37.61±18.78 years. There were 74 men and 76 women. There was Just one wound infection in our study, who had dressing for one week. The case was woman without serious disease, and a half day before surgery was admitted in the hospital. In the group without dressing, we did not have any wound infection. 5.3% were nervous in the no dressing group and the 17.3% of patients with dressing were anxious of having their bath with delay. Conclusion: According to the no impression of dressing on the rate of wound infection in the clean surgeries after first two days and also lack of considerable anxiety in the non dressing group, we recommend picking up the clean wounds dressing after 48 hours and make patients feel guaranteed

Effect of Oral Consumption of Magnesium on Glucose Concentration and Formalin Test in Diabetic Rats

Introduction & Objective: Magnesium is an essential metal in carbohydrate metabolism that causes activation and release of insulin. Increasing of blood sugar in diabetic patients resulted in decreasing of magnesium in the serum and its low concentration in urine. The aim of this study was to evaluate the effect of oral administration of magnesium on glucose concentration and formalin test in diabetic rats. Materials & Methods: This experimental study was done from April 2007 till July 2008 in medical school of Qazvin University of Medical Sciences. In this study 80 NMRI rats (Razi Co. Iran) categorized in ten groups control, diabetic without treatment of magnesium, diabetic with treatment of magnesium in one (1), two (2), three (3) and four (4) week(s). The other 4 normal groups were treated with magnesium in same timescales. In the diabetic groups, diabetes was induced with i.p. injection of 60mg/kg of streptozotocin. Besides of weight measurements, glucose concentration of animals was measured with enzymaticcolorimetric method. Pain scores were measured in formalin test. Statistical analysis was carried out by ANOVA and Tukey test. Results: The results showed that the difference in animal weight and glucose concentrations between control and diabetic groups was significant (P<0.0001). Glucose concentrations of magnesium treated diabetic groups were significantly different between 1 and 2 (P<0.005) 1 and 3 or 4 groups (P<0.0001) 2 and 3 (P<0.001) and 2 and 4 (P<0.01). Statistical differences between control and magnesium treated diabetic groups were significant between control and 1 (P<0.0001) control and 2 (P<0.05). Considering the weight of rats, there was no significant difference between diabetic in one side and 1 and 2 groups in other side while differences between diabetic and the other 3 and 4 groups were significant (P<0.001 and P<0.0001, respectively). In this study results from flinching and licking responses have been evoked by formalin in biphasic model of formalin test. Conclusion: Magnesium consuming in diabetic rats resulted in time dependent increasing of animals weight and decreasing of glucose concentration. Results from formalin test show hyperalgesic effects in diabetic and diabetic treated with magnesium groups in comparison with control groups

Prevalence of intra abdominal injuries due to penetrating trauma in Gorgan, Iran (2002-07)

Background and Objective: Trauma is the most common cause of death in all individuals between 1 and 44 years and the third most common cause of death regardless of age. The abdomen is the third most commonly injured region of the body. Some intra abdominal organ injured more than others, related to mechanism of injury, size and location of organ in abdominal cavity. This study was carried out to determine the prevalence of intra abdominal injuries due to penetrating trauma. Materials and Methods: This retrospective descriptive study was done on 114 patients admitted to 5 Azar hospital in Gorgan, Iran due to penetrating abdominal trauma during 2002-07. Gender, age, type of injury causes of trauma and hospitlalization period were obtained form patients files. Results: 92.1% of patients were male. The mean age of subjects was 24.8 years (9-70 years) with highest frequency between 20-24 years. Two (1.8%) deaths directly related to abdominal stab wounds related to hemorrhagic shock. The most common cause of penetrating abdominal injury was knife wound (78.9%). The mean time spent in hospital was 4.6±2.8 days. In 53 patients, cause of trauma were either related to pentration into peritoneum or passing through in. Small intestine injuries (14 %), rupture of diaphragm and concurrent lung injuries (7%) were the common damage organs. Conclusion: This study showed that the knife was the main cause of abdominal penetrate trauma and peritoneum was the most common damage tissue
