Study Objective:
To characterize the perioperative course of patients with Segawa syndrome undergoing anesthetic management.
Design:
Retrospective observational case study.
Setting:
Large tertiary medical center.
Patients:
Patients with Segawa syndrome who underwent procedures requiring anesthetic management at our institution from January 1, 2004, through July 31, 2015.
Measurements:
The health records of patients with Segawa syndrome.
Main Results:
Twelve patients with Segawa syndrome underwent 25 procedures requiring anesthetic management, including 20 operations with general anesthesia. Succinylcholine was administered in 6 cases and nondepolarizing neuromuscular blockers in 5 cases, all without adverse effects. Perioperative complications were unrelated to anesthetic management or underlying neurologic condition. In 16 operations, the patients were receiving levodopa therapy at the time of the procedure.
Conclusions:
In this cohort, patients with Segawa syndrome tolerated the anesthetic management, including neuromuscular blocker administration. Although these patients are frequently receiving levodopa therapy, no associated complications were noted.

Local Anesthetics: Clinical Application as Epidural Anesthesia
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
