Similarly, inadequate postoperative pain control, such as after laparoscopic cholecystectomy, can lead to serious complications. Minimizing these effects is essential for safe anesthesia and better patient outcomes. Therefore, evaluating iv fentanyl alone vs its combination with paracetamol is essential to enhance anesthesia care and patient outcome in resource limited settingsItem Incidence and Associated Factors of Intraoperative Arrhythmia in Adult Surgical Patients at Tikur Anbesa Specialized Hospital, 2025(Addis Ababa University, 2025-04-05) Eyerus Yaregal; Nura KedirIntraoperative arrhythmia are frequent, with nearly 11% of patients experiencing abnormal heart rates or rhythms during general anesthesia. While most are transient and clinically insignificant, some may signal underlying pathology or result from procedure specific or medication specific aetiologies, leading to hemodynamic instability. This research will enhance perioperative assessments and enable tailored interventions to prevent arrhythmia related complications, ultimately improving perioperative care and patient outcomesItem Comparing Hemodynamic Response to Laryngeal Mask Airway Insertion Versus Endotracheal Tube Intubation in Surgical Patients A Prospective cohort Study, Addis Ababa Ethiopia(Addis Ababa University, 2025-06) Eyerusalem Sisay; Biruk TesfayeEffective airway management is essential in anesthesia, with endotracheal intubation (ETI) widely regarded as the standard technique. However, ETI is associated with significant hemodynamic responses due to sympathetic stimulation during laryngoscopy, which may pose risks, particularly in patients with cardiovascular compromise. Laryngeal mask airways (LMAs) offer a less invasive alternative and are increasingly used in clinical practice. Despite their growing adoption, limited evidence exists comparing the hemodynamic effects of LMA insertion versus ETI in surgical patientsItem Incidence and Associated Factors of Constipation in Intensive Care Unit At Tikur Anbessa Specialized Hospitals,Addis Ababa, Ethiopia, 2024(Addis Ababa University, 2024-12-13) Hanna Abera; kedir, Nura; Jeregna, Gethachewconstipation lacks a universally accepted definition in ICU setting leading to varied incidence rate across studies from 83%. Multiple factors contribute to constipation in critical ill patients including, use of sedatives and opioids, neuromuscular blocking agents, vasopressors along with parental nutrition, inflammatory mediators, electrolyte disorders, inadequate administration of fluids, and lack of fiber in enteral nutrition. These has impacts like abdominal discomfort, decreased duration of enteral feeding and abdominal distension. It has also been associated with feeding intolerance, delirium, prolonged mechanical ventilation, and hospital stay.Item Incidence and Associated Factor of Intraoperative Cardiac Arrest in Patients Undergoing Elective Non-Cardiac Surgery at Public Hospitals Ethiopia, Addis Ababa(Addis Ababa University, 2025-03-31) Hanna Abebe; Wosenyeleh AdmasuIntraoperative cardiac arrest (IOCA) is a rare but potentially deadly event that can occur during surgical event. Globally, the incidence of IOCA ranges between 1.1 and 34.6 cardiac arrests per 10,000 procedures, with a survival rate of 35% to 46.6%. In most Ethiopian hospitals, there is still a shortage of resources which makes it difficult to provide patients with standard careItem Incidence and Associated Factors of Postoperative Negative Behavioral Changes among Paediatric Surgical Patients after General Anaesthesia at Selected Addis Ababa Public Hospitals, Ethiopia, 2024/2025: A Prospective Cohort Study(Addis Ababa University, 2025-06-05) Hibist Zegeye; Wosenyeleh AdmasuPostoperative negative behavioral changes (PONBC) are common psychological disturbances occurring in children after surgery or hospitalization, affecting over 50% of pediatric patients undergoing general anesthesia
