Perioperative Management of a Child With Pre-existing Diabetes Insipidus Undergoing Craniopharyngioma Excision: A Case Report.

Craniopharyngiomas are rare tumors arising in the suprasellar area of the brain and are more common in the pediatric age group. Due to the involvement of the hypothalamus, central diabetes insipidus (DI) is usually associated with such lesions. Patients with DI are at risk for significant electrolyte disturbances due to high urine output and the potential for sodium imbalance.

Median Effective Volume of 0.5% Ropivacaine for Ultrasound-guided Costoclavicular Block.

Background: The median effective dose of ropivacaine required for producing an effective costoclavicular block has not yet been determined. The authors conducted this dose-finding study with the objective of determining the median effective dose of 0.5% ropivacaine required to produce a successful costoclavicular block for surgical anesthesia in 50% of the patients (ED50) as well as the calculated dose required for effective blockade in 95% of the patients (ED95).
