ABSTRACT
Long QT syndrome is a cardiac repolarisation disorder that can occur with clinical symptoms such as dizziness, fainting, life-threatening arrhythmias and sudden cardiac death, and its incidence is increasing in the general population. A careful anaesthetic management is required for patients with this syndrome because of the risk of torsades de pointes and malignant arrhythmias. In this case report, we discuss the anaesthetic management of a seven-year-old patient with congenital long QT syndrome that was diagnosed during the preoperative evaluation.
ABSTRACT
Appendiceal anomalies are extremely rare malformations that are usually found in adult populations as an incidental finding. Agenesis and duplication of the appendix have been well documented, but we know of only three reported cases of a horseshoe appendix. A 64-year-old woman admitted to the emergency department. A provisional diagnosis of acute appendicitis was made, and the patient was taken to the operating room. While appendectomy was being performed with a standard approach, the distal tip was seen to communicate with the cecum by another stump, or "horseshoe appendix". The aim of this report is to share our experience with this extraordinary finding.

BACKGROUND: With an increase in the frequency of interventional radiology procedures in pediatrics, there has been a corresponding increase in demand for procedural sedation to facilitate them. The purpose of our study was to compare the frequency of adverse effects, sedation level, patient recovery characteristics in pediatric patients receiving intravenous propofol fentanyl combination with or without ketamine for interventional radiology procedures. Our main hypothesis was that the addition of ketamine would decrease propofol/fentanyl associated desaturation. METHODS AND MATERIALS: Sixty consenting American Society of Anesthesia physical status I-III pediatric patients undergoing interventional radiology procedures under sedation were studied according to a randomized, double-blinded, institutional review board approved protocol. Group 1 received propofol 0.5 mg.kg(-1) + fentanyl 1 microg.kg(-1) + ketamine 0.5 mg.kg(-1), and group 2 received propofol 0.5 mg.kg(-1) + fentanyl 1 microg.kg(-1) + same volume of %0.9 NaCl intravenously. RESULTS: While apnea was not observed in any of the groups, there were three cases (10%) in group 1, and nine cases (30%) in group 2 with oxygen desaturation (P = 0.052). In group 1, 12 (40%) patients and, in group 2, 21 (70%) patients required supplemental propofol during the procedure (P = 0.021). There was no evidence for difference between groups in terms of other side effects except nystagmus. CONCLUSIONS: In conclusion, addition of low dose ketamine to propofol-fentanyl combination decreased the risk of desaturation and it also decreased the need for supplemental propofol dosage in pediatric patients at interventional radiology procedures.
