Immediate Extubation after Aortic Valve Surgery Using High Thoracic Epidural Anesthesia.
Abstract Purpose: Fast-track anesthesia has gained widespread use in cardiac centers around the world. No study has focused on immediate extubation after aortic valve surgery. This study examines the feasibility and hemodynamic stability of immediate extubation after simple or combined aortic valve surgery using thoracic epidural anesthesia. ⋯ There were no complications related to TEA. Conclusions: Immediate extubation is feasible after aortic valve surgery with high thoracic epidural analgesia and maintenance of hemodynamic stability throughout surgery. Immediate extubation after aortic valve surgery is a promising new path in cardiac anesthesia.

Over the past one hundred years, the development of pancreaticoduodenectomy (PD) has always involved the struggle against pancreatic leakage. Until now, leakage of the pancreatic anastomosis has remained a common and serious complication after PD. Various methods of dealing with the pancreatic stump for prevention of pancreatic anastomotic leakage have been described. No matter which method is used, however, pancreatic anastomotic leakage is still most likely to occur when anastomosis involves a normal and soft pancreas. ⋯ Binding pancreaticojejunostomy is a safe and reliable anastomotic procedure to effectively minimize leakage even when the texture of the pancreas is soft and normal.

Electroneutral cation-chloride cotransporters in the central nervous system.
Several members of the cation-chloride cotransporter (solute carrier family 12, SLC12) gene family are expressed within the central nervous system, with one family member, the K+-Cl- cotransporter KCC2, exclusive to neurons. These transporters are best known for their roles in cell volume regulation and epithelial salt transport, but are increasingly receiving attention in neuroscience. ⋯ This relationship has important implications for neuronal development, sensory perception, neuronal excitability, and the response to neuronal injury. Finally, the association between loss of function in the K+-Cl- cotransporter KCC3, with a severe peripheral neuropathy associated with agenesis of the corpus callosum, has revealed an unexpected role for K+-Cl- cotransport in the development and/or maintenance of both the central and peripheral nervous systems.

Postoperative vomiting remains a common complication of general anesthesia and occurs more frequently in children than adults. Prophylactic antiemetics have limited efficacy and have a potential for side effects. The new 5 HT3 antagonists are effective but expensive, while the older less expensive drugs such as droperidol have come under disrepute because of the potential for serious, life-threatening, cardiac arrhythmias. This review examines the literature to aid practicing anesthesiologists in the choice of patient who will benefit from prophylactic antiemetics. ⋯ Anesthesiologists should practice evidence-based medicine in reducing the common anesthetic complication of postoperative vomiting by an individualized approach that balances the choice of drugs with the expected risk of postoperative vomiting for cost-effective management.

Submental Orotracheal Intubation: An Alternative to Tracheotomy in Transfacial Cranial Base Surgery.
This retrospective study evaluated the safety and efficacy of submental intubation not only for trauma treatment but also for oncological cranial base surgery. The medical records of 24 patients who underwent submental intubation from 1996 to 2002 were reviewed. There were 6 procedures for craniofacial trauma, 12 transmaxillary approaches to the clivus for clivus chordomas, and 6 transmaxillary approaches to the cranial base for chondrosarcomas. ⋯ It avoids the complications associated with tracheostomy. It also permits considerable downward retraction of the maxilla after a Le Fort I osteotomy and is associated with good clival exposure. Furthermore, it does not interfere with maxillomandibular fixation at the end of the surgery.
