The objective of this case report is to present the successful use of regional cerebral oxygen saturation (rScO2) monitoring guided cerebral protection for cesarean delivery in a parturient with Takayasu's arteritis at 38weeks' gestation. The parturient presented with impaired cerebral and renal perfusion. Titrated epidural anesthesia was performed. During the procedure, we used rScO2 guided cerebral protection strategies, which helped to optimize cerebral oxygen delivery and prevent cerebral complications.

Case Reports
General anesthesia in a patient with citrullinemia using Precedex as an adjunct to prevent delayed emergence.
Citrullinemia type I is a rare autosomal recessive genetic condition that causes reduced activity of the enzyme, argininosuccinate synthase, which is needed for proper urea metabolism. The end result is hyperammonemia which can cause life-threatening neurologic symptoms and global developmental delay. Previous case reports of the anesthetic management of patients with citrullinemia describe delayed recovery possibly related to elevated ammonia levels postoperatively or choice of intraoperative anesthetics which have included narcotics. ⋯ Postprocedure, her ammonia level was less than 9 μmol/L. She appeared to be free of pain, was tolerating gastric tube feeds postprocedure, and was discharged to home on the day of surgery. Effective management of ammonia levels in this patient using preoperative hydration and dexmedetomidine as an adjunct to general anesthesia may have helped to prevent delayed emergence.

We describe a novel technique of real-time ultrasound-guided superior laryngeal nerve and translaryngeal blocks in 4 patients with anticipated difficult airways. All patients had altered neck anatomy, and 1 had a prior unsuccessful awake fiberoptic bronchoscopic intubation. For block performance, an 11-mm broadband curved array transducer with a scanning frequency between 8 and 5 MHz (Sonosite, Bothell, WA) was used for anatomical structure identification, needle guidance toward each superior laryngeal nerve and through the cricothyroid membrane, and deposition of local anesthetic in the appropriate location. This was followed by successful awake fiberoptic bronchoscopic endotracheal intubation in all cases.

The green color in urine may suggest the presence of a severe pathology needing treatment. Many different potential causes of green urine have previously been reported. In our case, after ruling out other potential causes of green urine, it was suggested that the surgical manipulation of the paralytic ileum might have induced the reabsorption of the methylene blue which had been retained in the bowel (bezoar effect), even 96 hours after the nasogastric administration.

Observational Study
Association between preoperative maternal anxiety and neonatal outcomes: a prospective observational study.
Preoperative anxiety can be associated with poor postoperative clinical outcomes. We aimed to assess whether preoperative maternal anxiety level of obstetric patients scheduled for elective cesarean surgery has an effect on clinical outcome of the newborn. ⋯ We concluded that there was no relationship between preoperative maternal anxiety scores and Apgar scores at the first and fifth minute.
