    Ultrasound-Guided Unilateral Posterior TAP Block for Lower Abdominal Surgery in Children
    (Mongolian National University of Medical Sciences, 2021-09-14) ; ;
    Objectives: This study aimed to evaluate the analgesic effect of ultrasound-guided transversus abdominis plane block in children. Methods: Children between 3-18 years of age on whom lower abdominal surgeries were preformed are included in this random control trial (RCT). The parents signed a written consent form. Patients were randomized into control and study groups. Every group was divided into subgroups either with or without inflammation. Results: There were no differences between the two studied groups regarding demographic and clinical characteristics. Hemodynamics were more stable in the study group than in the control group. After induction, BP decreased in all groups and increased after surgical incision except for the transversus abdominis plane elective (TAP + Elec) group. An elevated white blood cell count was used as the mean indicator of inflammation. The opioid usage during the operation was significantly different in the subgroups (p = 0.000). The relationship between WBC and opioid usage was weak, positive, and statistically significant. Postoperative pain and pain medication requirements were lower in the TAP block group. Conclusion: Transversus abdominis plane block under ultrasound guidance is easy, safe, reliable, and adequate for analgesia in children. This method can decrease surgical and postoperative pain and analgesic requirements.

    Invasive Hemodynamic Monitoring and Arterial Blood Gas Exchange During Spinal vs General Anesthesia for Cesarean Delivery in Mongolian Parturient
    (Mongolian National University of Medical Sciences, 2024-12-12) ; ; ;
    Objective: This study investigated the accuracy and precision of continuous, invasive blood pressure obtained using the arterial line system in patients undergoing cesarean section with spinal and general anesthesia. Methods: A total of 150 parturient women who underwent C-sections from July 1, 2021, to Dec 30, 2023, were divided into two groups: the GA (general anesthesia) group (n=50) and the SA (spinal anesthesia) group (n=100). In this prospective observational study, we measured and compared the changes in hemodynamic fluctuation and arterial blood gas deviations under C-section with either spinal or general anesthesia. Results: One hundred fifty patients were recruited for the study after exclusions, and data were analyzed for 150 patients. There were no significant differences in the time from anesthesia to incision, the operation duration, infused crystalloid volume, blood loss, and urine output. The most frequent complications were surgery hypotension, tachycardia, nausea, and headache in the SA group, and tachycardia, hypertension, in the GA group These complications may cause SA’s impact on the sympathetic nerves, resulting in dilated blood vessels and reflex tachycardia. Conclusion: It has been suggested that the choice of anesthesia technique has a significant impact on hemodynamic stability during cesarean section.
