Case ReportsAnesthetic management of pediatric patients with Emanuel syndrome.
Emanuel syndrome is a rare anomaly associated with multiple systemic malformations. We present two cases involving pediatric patients with Emanuel syndrome. The first patient presented with micrognathia and had patent ductus arteriosus and a single kidney. ⋯ The second patient did not present with micrognathia and was not difficult to intubate. A thorough examination of the heart, kidney, and spinal cord is important when planning the anesthetic management of patients with Emanuel syndrome. Moreover, adequate preparation for a difficult airway is essential, and the Airtraq(®) device may be useful for intubating patients with Emanuel syndrome with micrognathia.

Observational StudyA short period of fasting before surgery conserves basal metabolism and suppresses catabolism according to indirect calorimetry performed under general anesthesia.
It is recommended that the period of fasting before elective surgery should be shortened to facilitate a rapid recovery by preventing catabolism. We examined the effects of a short period of fasting on metabolism by performing indirect calorimetry (IC) under general anesthesia. A prospective observational study involving 26 consecutive patients who underwent elective surgery and whose metabolism was evaluated using IC during anesthesia was conducted. ⋯ The REE, VCO2, and RQ of group L (17.7 ± 2.3 kcal/kg/day, 118.5 ± 20.8 ml/min, and 0.71 ± 0.12, respectively) were significantly lower than those of group S (19.7 ± 2.3 kcal/kg/day, 143.6 ± 30.9 ml/min, and 0.81 ± 0.09, respectively) (P < 0.05). In group L, the relationship between REE and BEE was weaker (r(2) = 0.501) and the BEE-REE slope was less steep (REE = 0.419BEE + 509.477) than those seen in group S (r(2) = 0.749 and REE = 1.113BEE - 376.111, respectively). Our findings suggest that a short period of fasting (<8 h) before surgery is more strongly associated with the conservation of basal metabolism.

Comparative Study Observational StudyCorrelation of cardiac output measured by non-invasive continuous cardiac output monitoring (NICOM) and thermodilution in patients undergoing off-pump coronary artery bypass surgery.
This observational study was designed to evaluate the clinical value of cardiac output (CO) obtained via bioreactance (NICOM™) as compared with values of CO obtained via thermodilution (using pulmonary artery catheter, Vigilance™) and the thoracic bioimpedance (BioZ.com™), in patients undergoing off-pump coronary artery bypass surgery. ⋯ The NICOM device is a safe, convenient, and reliable device for measuring continuous non-invasive cardiac output and cardiac index, and the trends of change in CO during the surgery are similar between NICOM and PAC.

Case ReportsDexmedetomidine and ketamine combination for a patient with xeroderma pigmentosa.
Patients of xeroderma pigmentosa (XP) have increased sensitivity to ultraviolet light and a defective nucleotide excision repair (NER) mechanism in their DNA. Several types of neurological, dermatological, and ophthalmological complications are common in these patients. ⋯ Some reports have shown uneventful conduct of total intravenous anesthesia in patients of XP. The authors report a case of XP in a young girl for surgery, previously anesthetized with delayed recovery, managed successfully with a combination of intravenous dexmedetomidine and ketamine.

Despite the many benefits of percutaneous thoracic sympathectomy, it also has serious complications such as pneumothorax. This study was conducted in order to determine the safe percutaneous entering window and angles for the needle during T2 and T3 thoracic sympathectomy avoiding pneumothorax. ⋯ The covariates' relationship and interindividual variability resulting from the mixed-effect analysis enhanced individual prediction for safe widows.
