In light of the contemporary developments in all the different sciences and technological changes, and the increase in the environmental impacts of production processes, it is required of the Iraqi economic units to use modern technologies applied in the world, to keep abreast of these developments and adhere to the legislation related to environmental protection on the one hand, and to increase the efficiency and effectiveness of labor activities and techniques, and this leads to consequently reduce production costs, and providing environmentally friendly production processes at the same time, and this requires the application of modern and advanced methods and methods, and accordingly, this research came to clarify the application of one of the modern techniques in cost management, which is the technique of re-engineering green processes and its role in improving the overall performance of the economic unit in particular, and the performance of in particular Total productive maintenance, Thus, the aim of the research is to highlight that green process reengineering technology has a role in improving the performance of Total productive maintenance. To develop the Iraqi industrial sector, the sulfuric acid plant in Al-Furat Company for Chemical Industries and Pesticides was adopted as a sample for research, as it is one of the Iraqi industrial economic units seeking development and facing great and growing competition. Total production maintenance, this hypothesis has been proven by applying green process reengineering to the production processes of the research sample factory. The research reached several conclusions, the most important of which is that the application of green process reengineering technology steps contributes to reducing costs by improving the performance of Total productive maintenance, and helps the research sample to protect the environment, and presented a set of recommendations that contribute to the development of the research sample and environmental protection.

Background: Laparoscopic surgery is associated with more favorable clinical outcome than conventional open surgery. This might be related to the magnitude of tissue trauma and tissue stress response. This study compares the intensity of tissue injury by assessing plasma C-reactive protein (CRP), lactic dehydrogenase (LDH), and cancer antigen 125 (CA 125) in patients undergoing laparoscopic hysterectomy compared to abdominal hysterectomy.Methods: This study was conducted at Ain Shams University Maternity Hospital from May 2018 to February 2020. 74 women candidate for hysterectomy were recruited and randomized into two groups: group A included 37 cases who underwent abdominal hysterectomy, and group B included 37 cases that underwent laparoscopic hysterectomy.Results: CRP, LDH and CA125 significantly increased post-operatively in both groups. Postoperative mean serum CRP, LDH and CA125 were significantly higher in the laparotomy group (10.84±2.47, 262.21±76.77, and 13.41±2.6 respectively) compared to laparoscopy group (7.92±2.25, 148.53±43.56, 11.79±2.77 respectively) (p<0.05).Conclusions: Surgery is a significant cause of tissue injury that can be assessed by specific markers. We suggest that laparoscopic surgery causes less tissue damage as assessed by lower postoperative CRP and LDH values, which might account for the earlier recovery and reduced hospital stay in laparoscopic surgery.

Objectives: To evaluate the efficacy of Decompressive Craniectomy (DC) on the postoperative clinical state of the patient to define a line of management of these cases. Take in considerations the surrounding circumstances of the patient till he reaches the ER in Egypt and the hospital resources. Methods: 200 patients suffering from acute traumatic brain injury causing DCL resulted from different pathologies causing increased ICP. In group A, patients with acute TBI were managed by surgical intervention in the form of Decompressive Craniectomy and in the control group B, patients were managed by medical treatment. The age range was from 8 to 65 with no history of associated medical disorders with exclusion criteria of non-traumatic causes of increased ICP. Results: Data collected showed: male to female ratio of 3:1. The most common mode of injury was falling from height. Mean time from injury to operative intervention was 4 hours. The leading initial symptoms were DCL. In group A the overall mortality was 60%, functional recovery rate was 30%, and left severely disabled or vegetative was 10%. 50% of the cases had associated injury. 20% suffered from post-operative complications. Conclusion: DC is the ideal solution for the management of acute TBI with persistent increased ICP when the other medical management fails, given an early intervention and taking into consideration other factors affecting surgical outcome.

Background Intraoperative myocardial preservation is essential in pediatric cardiac surgeries. The combination of hypothermia and hyperkalemic cardioplegia is commonly used. Histidine-tryptophan-ketoglutarate (HTK–Custodiol) is a long-acting crystalloid cardioplegia which induces cardiac arrest by reducing the extracellular sodium concentration. Cold blood cardioplegia has many modifications differing in the blood: crystalloid ratio, buffers, substrates, and final potassium concentration which induces cardiac arrest in diastole as the main role. We compared cold histidine-tryptophan-ketoglutarate crystalloid (HTK) solution with hypothermic hyperkalemic blood (HHB) cardioplegia solution regarding their efficacy in myocardial preservation in patients undergoing total repair of non-cyanotic congenital cardiac defects. We assessed postoperative cardiac troponin level, myocardial function, inotropic support, intensive care unit (ICU) length of stay, hospital length of stay, and the incidence of prolonged postoperative mechanical ventilation as indicators of myocardial protection. Results This interventional, single-blinded, randomized, comparative, and prospective clinical study was conducted randomly on 60 patients, aged between 6 and 24 months undergoing total surgical repair. We found no statistically significant difference regarding patients’ personal, demographics, and operative details (surgery duration, cardiopulmonary bypass time, aorta clamp time). However, patients who were given HTK cardioplegia were found to stay less in the ICU (with a p value <0.05). However, there was no statistically significant difference between both groups as regards hospital length of stay. Also, all patients were extubated in less than 24-h duration. There was a statistically significant difference between both groups regarding troponin levels after 8, 12, and 24 h post-bypass in favor of the HHB solution. Interestingly, no significant correlation was proved between both groups regarding myocardial function (EF%, FS) and level of inotropic support (assessed by maximum vasoactive inotropic score). Conclusions Hypothermic hyperkalemic blood cardioplegia showed better results in myocardial preservation than the cold histidine-tryptophan-ketoglutarate solution in the repair of noncyanotic congenital cardiac defects.
