The purpose of this study was to compare the effects of intravenous administration of propofol and isoflurane for anesthesia maintenance on the amount of blood loss and hemodynamic status during the surgery. Materials & Methods: In this clinical trial single blind study, 100 patients undergoing spinal surgery with ASA I were randomly assigned in two groups P and I in group P we used intra-venous propofol (100-200 ?/kg/min) plus nitrous oxide 50% (50 patients) and in group I we applied isoflurane, (MAC 1.5-2) plus nitrous oxide 50% (50 patients) for maintenance of an-esthesia. For determining and comparing blood loss in each group, total volume of blood loss during surgery was determined by weighting of blood on gausses and volume of blood in suction bottle. The amount of hemoglobin, the need for blood transfusion and satisfaction of surgeon from operative field during surgery were also assessed. Mean arterial pressure and heart rate were measured every 5 minutes intra operative and were compared in the two groups. The data was analyzed by SPSS and t-test. Results: The total volume of blood loss in propofol and isoflurane groups was 352.7± 303.5 and 450.48±321.8 ml, respectively. Total blood loss, and blood loss per min was significantly lower in the propofol group and isoflurane group (P=0.049, P=0.015). Surgeon satisfaction with bleeding of surgery field based on the Boezzart scale was higher in the propofol group. Decrease in hemoglobin concentration and hematocrit were less in the propofol group com-pared to the isoflurane group. Mean arterial pressure during surgery with the propofol group was 85.71±9.7 versus 80.25±8.04 mmHg in the isoflurane group, which was significantly lower in the isoflurane group (P=0.003). The difference between the heart rate during surgery and the need for blood transfusion in the two groups was not significant. Conclusion: In view of the decreased amount of blood loss and hemoglobin reduction, as well as improving surgical field, intravenous propofol is preferred to isoflurane for anesthesia maintenance during spine surgery. So, we recommend the maintenance of anesthesia with intravenous propofol during spine surgery.}, Keywords = {Anesthesia , Isoflurane , Hemorrhage , Propofol , Spine , Surgery }, volume = {21}, Number = {4}, pages = {255-262}, publisher = {Hamadan University of Medical Sciences}, url = {http://sjh.umsha.ac.ir/article-1-62-en.html}, eprint = {http://sjh.umsha.ac.ir/article-1-62-en.pdf}, journal = {Avicenna Journal of Clinical Medicine}, issn = {2588-722X}, eissn = {2588-7238}, year = {2015} } @article{ author = {Nouri, Saeed and Khorshidi, Amirhosein and Farokhi, Shima and Sharif, Mohammadrez}, title = {Comparing the Effect of Ferric Sulfate and Zinc Chloride in Controlling Liver Bleeding in an Animal Model Study}, abstract ={Introduction & Objective: Despite all the progress in surgical sciences, controlling parenchy-mal hemorrhage especially in liver parenchyma, is still one of the challenges surgeons face in saving patients’ lives. Therefore, introducing an effective method to control liver bleeding is an important research priority. This study attempts to determine the haemostatic effect of fer-ric sulfate and zinc chloride and compare it with that of the standard method (simple suturing technique) in controlling bleeding from liver parenchymal tissue. Materials & Methods: This is an experimental study. In this animal model study 70 male Wistar rats were randomly allocated into seven groups. An incision, two centimeters (cm) long and half a cm deep, was made on each rat’s liver and the hemostasis time was measured once us-ing ferric sulfate and zinc chloride with different concentrations (15%, 25%, and 50%) and then using the control method (i.e. controlling bleeding by simple suturing). The liver tissue was examined for pathological changes. Finally, the hemostasis times were entered into SPSS software and analyzed using Kruskal- wallis test, Mann-Whitney, Kolmogorov-Smirnov test. Results: The mean time to hemostasis in groups of ferric sulfate concentration of 50%, 25% and 15%, were, respectively, 9.50±1.17, 21.80±2.2,and 37.8±2.7 seconds, and in groups of zinc chloride concentration of 50%, 25% and 15%, were, respectively, 15.80±1.75, 30.20±2.57 and 49.00±2.21 seconds also in the control group (suture) mean time of hemosta-sis was 91.30±7.30 seconds. The haemostatic times of different concentrations of ferric sul-fate and zinc chloride were significantly less than that of the control group (P< 0.01). There was a statistically significant difference between different concentrations of ferric sulfate and zinc chloride haemostatic times (P < 0.01). The pathologic examination showed the highest frequency of low grade inflammation based on the defined pathological grading. Conclusion: Ferric sulfate and zinc chloride compared to the control method (i.e. controlling liver bleeding by simple suturing) needs less time to control liver bleeding.

The purpose of this study was to investigate the effects of subcutaneous infiltration of ketamine on postoperative pain reduction and hemodynamic status of patients after elective cesarean section. Materials & Methods: This study was designed as a double blinded prospective, randomized clinical trial and 60 cases of women undergoing elective cesarean section under spinal anes-thesia were randomly assigned into two groups. For 30 cases in the ketamine group, infiltra-tion of subcutaneous ketamine 0.5 mg / kg was administered after closure of surgical inci-sion. 30 patients in the placebo group received subcutaneous infiltration of saline. During the patient's recovery time and after transferring to the ward, the VAS of pain and vital signs were continuously assessed. if VAS ≥ 3, 100 mg diclofenac suppository was administered and if there were no response, 30 mg intravenous pethidine was also administered. Prescribed number of suppositories and pethidine dosage were compared. The complications, such as hallucination, nystagmus, nausea, vomiting and drowsiness in patients were also recorded and compared. Statistical analysis was performed by SPSS16 software and ?2 and t-test. P< 0.05 was considered statistically significant in all of the cases. Results: In the course of systolic blood pressure, heart rate and arterial blood oxygen satura-tion during the first 24 hours, no significant differences were mentioned between the two groups.

The aim of the present study was to evaluate the effects of diazinon on cholinesterase activity in blood serum and erythrocytes of male and female rats and to assess the protective role of vitamin E. Materials & Methods: In this experimental study, 60 adult wistar rats including 30 male and 30 female rats were selected and divided into 5 groups (n = 6): control group (without any intervention), sham group (received only pure olive oil daily), experimental group 1 (DZN daily, 60 mg/kg), experimental group 2 (received DZN+ vitamin E daily, with the same dose) and experimental group 3(received vitamin E daily 200 mg/kg). Diazinon and solvent were injected intraperitoneally and vitamin E was given by gavage. After 2 weeks 3 ml blood was taken from the heart tissue, and titrimetric and Ellman’s method respectively were used for serum and erythrocyte cholinesterases activity assay. Results: In both genders, due to administration of diazinon, we observed significant reduction in serum and erythrocytes cholinesterase activity. The use of vitamin E increased serum and erythrocytes cholinesterase activity in experimental group 2 of female rats but inhibition in erythrocyte and serum cholinesterase activity was not recovered in experimental group 2 of male rats. Conclusion: According to a further reduction of these enzymes activity in female rats with the use of diazinon, it can be concluded that female rats are more sensitive than male rats and it seems that vitamin E as an antioxidants has a protective effect on cholinesterase activity and reduces the toxicity of DZN.}, Keywords = {Cholinesterase , Diazinon , Rats , Vitamin E}, volume = {21}, Number = {4}, pages = {294-303}, publisher = {Hamadan University of Medical Sciences}, url = {http://sjh.umsha.ac.ir/article-1-67-en.html}, eprint = {http://sjh.umsha.ac.ir/article-1-67-en.pdf}, journal = {Avicenna Journal of Clinical Medicine}, issn = {2588-722X}, eissn = {2588-7238}, year = {2015} } @article{ author = {Mohammadi, Hadi and Jamalpour, Mohammadrez}, title = {Assessment of Performance of Tube Reduction Screw in Reduction of Oblique Mandibular Body Fractures: An Experimental Study in Slaughtered Sheep}, abstract ={Introduction & Objective: The highest rate of non-anatomic reduction of fractures is usually seen in oblique mandibular body fractures.
