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.

Some complications may occur, depending on the method of spinal anesthesia and anesthetic agents. One of the most common neurological complications is radiculopathy caused by intrathecal anesthesia. In this case report, we aimed to present the therapeutic approach of a patient with low back pain, including neuropathic components, after spinal anesthesia.

The syndrome is thought to be a consequence of otosomal dominant mutation. Important factors in anesthetical management of these patients include; difficult airway, cardiologic problems, obstructive sleeps apne, hypotoni and maligns hyperthermia risks. In this case report we aimed to discuss anesthesic management of a patient with Kabuki syndrome-a rare clinical entity in our country- .

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. 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. 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. 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.
