In the field of children's blood transfusion under anesthesia, the use of artificial intelligence (AI) and machine learning (ML) is regarded as innovative tools that enhance patient safety levels. This article examines and reviews the scoping literature on the use of artificial intelligence in pediatric blood transfusions during anesthesia, with the aim of identifying solutions, challenges, and future opportunities in this field.<br><strong>Methods:</strong> The study, conducted from early 2024 to May 2024, aimed to evaluate the effectiveness of artificial intelligence (AI) and machine learning (ML) in predicting blood transfusion needs and bleeding risks in pediatric anesthesia. Relevant keywords, including artificial intelligence, machine learning, predictive model, neural network, predictive algorithm, blood transfusion, children, pediatric, neonates, anesthesia, surgery, and operation, were extracted from the Medical Subject Headings (MeSH). A comprehensive search strategy was independently implemented in Web of Science, PubMed, Scopus, and Google Scholar databases<br><strong>Results:</strong> The search strategy initially identified 260 articles. After a systematic screening process, 60 duplicate articles were excluded. Subsequently, careful screening of titles, abstracts, and full texts eliminated an additional 195 articles, resulting in a final selection of 5 relevant English-language articles. Based on these studies, factors such as the type of surgery, the machine learning models used, decreases in hemoglobin and hematocrit levels before surgery, prolonged surgery, as well as the young age and low weight of pediatric patients, were identified as indicators of the increased risk of blood transfusion during surgery and anesthesia.<br><strong>Conclusion:</strong> Based on the findings of the studies, artificial intelligence (AI) and machine learning (ML) have shown significant advancements in pediatric blood transfusion under anesthesia. This technology offers notable benefits, including high accuracy in predicting transfusion requirements and the ability to make timely decisions in critical situations.

Volume responsiveness is also indicated by this index. Considering the non-invasiveness of the PVI index and its predictive value, its use could be highly beneficial. Thus, we decided to evaluate the correlation between Pleth Variability Index in prone position and bleeding and volume responsiveness in patients undergoing lumbar spine surgery under general anesthesia.<br><strong>Methods:</strong> 119 patients who were candidates for lumbar spine fixation surgery were studied in the prone position during surgery. Aside from demographic information, vital signs and PVI levels were recorded after induction of anesthesia, 5 minutes after induction of anesthesia, immediately after changing position from supine to prone, 5 minutes after changing position from supine to prone, at the end of the operation, immediately after shifting position from prone to supine, and after switching position from prone to supine for 5 minutes. Accordingly, the amount of bleeding and the type and amount of fluid received during the operation were recorded.<br><strong>Results:</strong> Results revealed that demographic factors (gender, age, weight, height), hemodynamic factors (heart rate, blood pressure, SPO2), cardiac EF, and initial Hb levels, and changes in position from supine to prone did not affect the PVI process. In contrast, PVI has decreased due to an increase in intraoperative fluid intake. Notably, the amount of fluid received by different people (taking into consideration weight, bleeding, etc.) had no effect on PVI decreasing.<br><strong>Conclusion:</strong> The PVI provides a cheap and readily accessible way to determine volume responsiveness, which is unaffected by various individual variables and can be performed in a prone position.</p> 2024-12-30T00:00:00+0330 ##submission.copyrightStatement## https://aacc.tums.ac.ir/index.php/aacc/article/view/1066 The Effect of Implementing an Educational Program on Adherence to Treatment and Self-Compassion of Patients with Multiple Sclerosis 2025-02-26T08:51:59+0330 Hanie Dahmardeh haniedahmardeh@gmail.com Mahnaz Rakhshan mzrakhshan@gmail.com Farshid Saeedinezhad farshidsaeedinezhad@gmail.com Roya Dokoohaki dokoohaki9@gmail.com <p><strong>Background:</strong> Multiple sclerosis, as one of the most important causes of disability in the world, can cause a feeling of despair in a person to be compassionate and follow his treatment, so it is important to use self-compassion methods for these patients.

This case report delineates the emergency placement of a central venous catheter (CVC) through the right internal jugular vein in a 63-year-old female patient positioned prone during spinal surgery. The necessity arose following significant intraoperative blood loss and the failure of peripheral venous access, presenting unique challenges due to the patient's position and the absence of sonographic guidance. The procedure was successfully executed by anatomically identifying the insertion site and utilizing a posterior lateral approach, which underscores the feasibility and urgent need for CVC placement in atypical scenarios. The patient demonstrated significant improvement with stable postoperative outcomes, emphasizing the importance of adaptability in clinical practices. This case contributes to the limited but growing body of literature on prone position CVC insertion, highlighting its viability in emergencies, despite inherent risks and technical difficulties. The findings advocate for further research and development of guidelines to enhance patient safety and procedural success in complex clinical settings.</p> 2025-01-07T00:00:00+0330 ##submission.copyrightStatement## https://aacc.tums.ac.ir/index.php/aacc/article/view/1079 Anesthetic Challenges and Strategies in a Child with Kawasaki Syndrome Undergoing Surgical Intervention: A Case Report 2025-02-26T08:52:30+0330 Alireza Babajani alirezababajani1368@gmail.com Pegah Arman pegah.arman96@gmail.com Ahmad Moradi ahmadmd_113@yahoo.com Parastoo Rahmati Torkhashvand rahmati.p1381@gmail.com Yasin Ghodarzi y.ghoodarzi1382@gmail.com <p>A 26-month-old male patient presented with swelling in the right hemi-scrotum, diagnosed as a hydrocele and a 44 x 14 mm hernia displacing the right testicle.

The cost and mortality caused by warfarin toxicity are very high and usually incurable and fatal. The most important action in the field of warfarin toxicity is to prevent its occurrence. To emphasize how warfarin toxicity occurs, a case is introduced in this regard. A 61-year-old man is found unconscious with a seizure on the street and transported to the hospital by Emergency Medical Services (EMS).&nbsp;In the emergency car, he received a diazepam injection for generalized seizures. His vital signs in the postictal state were as follows: blood pressure 82/44 mmHg, pulse rate 91 bpm, and oxygen saturation (SaO2) 93%. His past medical history includes an ischemic stroke and a myocardial infarction 12 years ago. He underwent Mitral valve repair 11 years ago and a mechanical-type Mitral valve replacement 2 years ago. After undergoing mitral valve replacement surgery, he continued taking warfarin and aspirin for 2 years without consulting a cardiologist or undergoing PT and INR tests. As a result, he suffered a massive intracerebral hemorrhage when his INR level rose above 6. It's important to note that he has no history of depression or suicide attempts. After experiencing decreased consciousness and seizures, he was quickly intubated. A brain CT scan revealed extensive evidence of intracerebral hemorrhage, and he was then transferred to the operating room for craniotomy. To manage the bleeding and because Prothrombin complex concentrate (PCC) was not available, the patient received two grams of fibrinogen, two units of Fresh Frozen Plasma (FFP), 10 mg of vitamin K, and one unit of Packed Red Blood Cells. Unfortunately, after a month-long stay in the ICU, the patient passed away as a result of Ventilator-associated pneumonia (VAP) and sepsis.</p> 2024-11-12T00:00:00+0330 ##submission.copyrightStatement## https://aacc.tums.ac.ir/index.php/aacc/article/view/1021 Large Pneumothorax Associated with Mechanical Ventilation in Patients with Chronic Respiratory Disease 2025-02-26T08:52:38+0330 Alireza Rahat Dahmardeh dr.dahmardeh@gmail.com Aliakbar Keykha aliakbar.keykha@gmail.com <p>Difficult intubation and mechanical ventilation are common causes of pneumothorax in critically ill patients. Patients with chronic respiratory tract disease are at high risk for pneumothorax caused by positive-pressure mechanical ventilation. A timely diagnosis of pneumothorax is critical as it may evolve into tension pneumothorax. In this case report, we report a patient who has a decreased level of consciousness due to opioid overdose. In the emergency room, she underwent mechanical ventilation and became conscious after a naloxone injection. After extubation, she has extensive subcutaneous emphysema. However, her hemodynamic and respiratory status is normal. The chest CT scan showed a large pneumothorax caused by mechanical ventilation.</p> 2024-11-02T00:00:00+0330 ##submission.copyrightStatement## https://aacc.tums.ac.ir/index.php/aacc/article/view/1016 Massive Gastrointestinal Bleeding, Consequences Interactions of Apixaban, Diltiazem and Aspirin: Case Report 2025-02-26T08:52:41+0330 Hossein Karballaei Mirzahosseini karbalayihossein1363@gmail.com Parinaz Shahriari Parinaz.shahriari2000@gmai.com Ehsan Yousefi-Mazhin ehsan_yousefi70@yahoo.com Atabak Najafi nadjafia@tums.ac.ir Amirmahdi Mojtahedzadeh amirmahdi.mojtahedzadeh@stud.semmelweis.hu Mojtaba Mojtahedzadeh mojtahed@sina.tums.ac.ir <p>Anticoagulation is the cornerstone of preventing thrombosis. Following the aging of society and the greater use of anticoagulant drugs, we see more serious complications in this group. The reduced occurrence of significant bleeding represents a notable benefit of direct oral anticoagulants (DOACs) in comparison to vitamin K antagonists. However, the unavailability of Andexanet alfa and Idarucizumab complicates the management of bleeding associated with DOACs. This case describes a 69-year-old man who presented with massive gastrointestinal bleeding, hemorrhagic shock, and loss of conciseness. He has been taking apixaban 2.5 mg twice a day, aspirin 80 mg once a day, and diltiazem 60 mg three times daily. Bleeding was controlled through transfusion of two units of fresh frozen plasma, five units of packed cell, four units of platelet, and tranexamic acid injection. Although hemorrhagic shock was successfully managed, he unfortunately passed away after three weeks of hospitalization following Ventilator-associated pneumonia and sepsis. In this case, we discuss the importance of the drug interaction of apixaban, diltiazem, and aspirin.</p> 2024-10-29T00:00:00+0330 ##submission.copyrightStatement## https://aacc.tums.ac.ir/index.php/aacc/article/view/1049 Ventilator-Associated Pneumonia Prevention Strategies in Patients with Brain Damage 2025-03-08T08:29:09+0330 Ali Jabbari amir_a_78@yahoo.com Shabnam Tabasi tabasi.dr@gmail.com Hassan Mirzaei mirzaei22@yahoo.com <p>&nbsp;&nbsp;&nbsp; No Abstract&nbsp; No Abstract &nbsp; No Abstract</p> 2024-12-11T00:00:00+0330 ##submission.copyrightStatement## https://aacc.tums.ac.ir/index.php/aacc/article/view/1072 Elevated Liver Enzyme after Cardiac Surgery by on Pump Method 2025-02-26T08:52:48+0330 Ali Jabbari amir_a_78@yahoo.com Shabnam Tabasi tabasi.dr@gmail.com Mansour Deylami mansour.deylami@gmail.com <p>Elevated liver enzymes after on-pump cardiac surgery indicate potential recovery delays, complications, and long-term damage. The heart-lung machine can cause liver injury, leading to longer hospital stays and risks from systemic inflammatory response syndrome (SIRS). Factors like mechanical stress and ischemia-reperfusion injury release inflammatory mediators that harm liver cells. Key markers of liver injury include alanine aminotransferase (ALT) and aspartate aminotransferase (AST), with ALT being more specific. Increased alkaline phosphatase (ALP) and gamma-glutamyl transferase (GGT) may suggest biliary problems. Ischemia-reperfusion injury occurs when blood flow is interrupted, causing oxidative stress that affects liver health. Cannulating the vena cavae can worsen liver congestion and damage, especially if improperly placed, risking ischemic injury and liver function impairment. Surgeons should consider pre-existing liver conditions, as they can worsen cannulation effects. Cardiopulmonary bypass (CPB) can disrupt liver microcirculation, affecting oxygen and nutrient delivery. Mechanical hemolysis from the machine can release toxic substances that harm the liver. Anesthetics and antibiotics may also elevate liver enzymes. Risk factors include prolonged CPB times, existing liver issues, older age, obesity, diabetes, kidney dysfunction, and chronic alcohol use. To manage liver enzymes, optimizing CPB techniques and monitoring liver function post-surgery are crucial. Understanding the inflammatory response linked to on-pump techniques can enhance patient care and outcomes.</p> 2024-11-25T00:00:00+0330 ##submission.copyrightStatement##
