Perioperative management of diabetes insipidus in children [corrected].
Managing children with diabetes insipidus (DI) in the perioperative period is complicated and frequently associated with electrolyte imbalance compounded by over- or underhydration. In this study the authors developed and prospectively evaluated a multidisciplinary approach to the perioperative management of DI with a comparison to 19 historical control children. Eighteen children either with preoperative DI or undergoing neurosurgical operations associated with a high risk for developing postoperative DI were identified and managed using a standardized protocol. ⋯ In all children managed in this fashion, perioperative serum sodium concentrations were generally maintained between 130 and 150 mEq/L, and no adverse consequences of this therapy developed. In the 24-hour period evaluated, the mean change in serum sodium concentrations between the historical controls was 17.6 +/- 9.2 mEq/L versus 8.36 +/- 6.43 mEq/L in those children managed by the protocol. Hyponatremia occurred less frequently in the children managed with this protocol compared with historical controls.

Case ReportsAcute parotitis following sitting position neurosurgical procedures: review of five cases.
Acute bacterial parotitis subsequent to major abdominal surgery is well documented, reportedly occurring in as many as 0.1% of patients. Postoperative parotitis has been reported between 1 to 15 weeks after surgery, commonly appearing within 2 weeks of the procedure. However, postoperative parotitis has not been reported previously after neurosurgical procedures. ⋯ The authors found that the side of the parotitis was on the opposite side of the head rotation. Dehydration therapy may also be a contributing factor. The objective of this paper is to state that parotitis is a possible complication in neurosurgical patients operated on in sitting position and to discuss its pathophysiology and treatment options.

Randomized Controlled Trial Comparative Study Clinical TrialJugular bulb oxygen saturation under propofol or sevoflurane/nitrous oxide anesthesia during deliberate mild hypothermia in neurosurgical patients.
Sevoflurane and propofol have been widely used as anesthetic agents for neurosurgery. Recent evidence has suggested that the influence of these anesthetics on cerebral oxygenation may differ. In the present study, the authors investigated jugular bulb oxygen saturation (SjO2) during propofol and sevoflurane/nitrous oxide anesthesia under mildly hypothermic conditions. ⋯ During mild hypothermia, SjO2 values were significantly lower in group P than in group S/N2O. The incidence of SjO2 less than 50% under mild hypothermic-hypocapnic conditions was significantly higher in group P than in group S/N2O. These results suggest that hyperventilation should be more cautiously applied during mild hypothermia in patients anesthetized with propofol and fentanyl versus sevoflurane/nitrous oxide/fentanyl.
