Purpose: Stroke is a leading cause of severe long-term disability and death worldwide. This study aimed to determine the genetic background, causative factors, and diagnostic and outcome measures of pediatric stroke in an area endemic to sickle cell disease (SCD). Patients and Methods: This retrospective review analyzed pediatric patients with acute stroke who were admitted to King Fahd Hospital of the University, Eastern Province, Saudi Arabia, between January and June 2019. We assessed 49 cases based on computed tomography (CT) and magnetic resonance imaging (MRI) findings. Patients with incomplete records or unavailable radiological images were excluded. Results: A high likelihood of familial coexistence of stroke was detected in patients with affected siblings (33%). Among various central nervous system manifestations, motor weakness (28.6%) and headache (20.4%) were the most common symptoms/signs. Hypoxic-ischemic encephalopathy (HIE) (28.6%), SCD (22.5%), and moyamoya disease (14.3%) were the most prevalent underlying etiologies. CT without intravenous contrast was the most used initial imaging technique (92.5%). An arterial blockage was more prevalent (53.4%) than a venous infarct (46.6%) (p = 0.041), while arterial ischemic stroke was more prevalent (56.5%) than hemorrhagic stroke (43.5%). The middle cerebral artery (MCA) was most affected (63.5%), followed by the anterior cerebral artery (22.7%) and posterior cerebral artery (13.6%). Most patients were managed with medical treatment (86.1%). No mortalities occurred during the initial hospital stay. The mean length of hospital stay was 12 days. Conclusion: HIE was the most prevalent etiology of pediatric stroke. Motor weakness and headache were the most common initial manifestations. Arterial ischemic stroke was more prevalent than venous or hemorrhagic stroke. Considering the rarity of pediatric stroke, future studies should be performed with a aborative effort nationally and internationally.

BACKGROUND AND OBJECTIVES: Ultrasound-guided regional anesthesia (UGRA) has become the criterion standard of regional anesthesia practice. Ultrasound-guided regional anesthesia teaching programs often use simulation, and guidelines have been published to help guide URGA education. This systematic review aimed to examine the effectiveness of simulation-based education for the acquisition and maintenance of competence in UGRA. METHODS: Studies identified in MEDLINE, EMBASE, CINAHL, Cochrane Central Register of Controlled Trials, and ERIC were included if they assessed simulation-based UGRA teaching with outcomes measured at Kirkpatrick level 2 (knowledge and skills), 3 (transfer of learning to the workplace), or 4 (patient outcomes). Two authors independently reviewed all identified references for eligibility, abstracted data, and appraised quality. RESULTS: After screening 176 citations and 45 full-text articles, 12 studies were included. Simulation-enhanced training improved knowledge acquisition (Kirkpatrick level 2) when compared with nonsimulation training. Seven studies measuring skill acquisition (Kirkpatrick level 2) found that simulation-enhanced UGRA training was significantly more effective than alternative teaching methods or no intervention. One study measuring transfer of learning into the clinical setting (Kirkpatrick level 3) found no difference between simulation-enhanced UGRA training and non-simulation-based training. However, this study was discontinued early because of technical challenges. Two studies examined patient outcomes (Kirkpatrick level 4), and one of these found that simulation-based UGRA training improved patient outcomes compared with didactic teaching. CONCLUSIONS: Ultrasound-guided regional anesthesia knowledge and skills significantly improved with simulation training. The acquired UGRA skills may be transferred to the clinical setting; however, further studies are required to confirm these changes translate to improved patient outcomes.
