Case ReportsContinuous spinal anesthesia and postoperative analgesia for elective cesarean section in a parturient with Eisenmenger's syndrome.
We describe the use of continuous spinal anesthesia (CSA) for an elective cesarean section in a 29-year-old parturient with Eisenmenger's syndrome at 30 weeks of gestation. It is essential in patients with Eisenmenger's syndrome to prevent significant increases in right-to-left shunt following the reduction in systemic vascular resistance. In this case, the patient hoped to be awake during the operation because of her fear of death. ⋯ In fact, sudden cardiovascular changes were avoided by the titration of local anesthetics and the operation was uneventful, although prompt treatment of hypotension was essential and adjustment of the anesthetic levels was difficult. Postoperative patient-controlled spinal analgesia provided satisfactory pain relief with hemodynamic stability and no significant side effects. However, thorough experience with the requisite techniques is critical in CSA because of the technical difficulty of the procedure, and anesthesiologists must gain such experience in less-demanding cases before attempting to administer it in patients presenting extreme challenges as described in this case report.

The volatile anesthetics halothane and isoflurane differentially modulate proinflammatory cytokine-induced p38 mitogen-activated protein kinase activation.
Volatile anesthetics affect the cardiovascular and immune systems. Toward a better understanding of the molecular mechanisms behind the modulation exerted by these agents, we focused on the effects of halothane and isoflurane on the activation of p38 mitogen-activated protein kinase (MAPK), which plays a critical role in the cellular responses to extracellular stimuli such as lipopolysaccharide (LPS) and proinflammatory cytokines, including tumor necrosis factor (TNF) and interleukin 1 (IL-1). ⋯ Our in vitro results indicate that the volatile anesthetics used in the clinical field and in animal experiments modify the p38 MAPK signaling cascade and suggest that the target molecules of the anesthetics are not unique and the anesthetics regulate them differentially at clinically relevant doses.

Comparative StudyAmsorb Plus and Drägersorb Free, two new-generation carbon dioxide absorbents that produce a low compound A concentration while providing sufficient CO2 absorption capacity in simulated sevoflurane anesthesia.
The properties of two new-generation CO(2) absorbents, Amsorb Plus (Armstrong Medical, Coleraine, UK) and Drägersorb Free (Drager, Lubeck, Germany), were compared with those of Amsorb (Armstrong Medical) and Sodasorb II (W.R. Grace, Lexington, MA, USA). ⋯ The new-generation carbon dioxide absorbents, Amsorb Plus and Drägersorb Free, produce a low concentration of compound A in the circuit while showing sufficient CO(2) absorption capacity.

Case ReportsConversion of atrial fibrillation to sinus rhythm during landiolol infusion.
A 71-year-old woman with a history of persistent atrial fibrillation underwent clipping of a ruptured cerebral artery aneurysm. During the surgery her cardiac rhythm was atrial fibrillation and the ventricular rate increased to 130 beats.min(-1). ⋯ Approximately 120 min after the landiolol infusion was started, the atrial fibrillation was converted to sinus rhythm. Her sinus rhythm was maintained until she left the operating room, even after discontinuation of landiolol.
