The actual incidence of neurologic dysfunction resulting from hemorrhagic complications associated with neuraxial blockade is unknown. Although the incidence cited in the literature is estimated to be less than 1 in 150,000 epidural and less than 1 in 220,000 spinal anesthetics, recent epidemiologic surveys suggest that the frequency is increasing and may(More)
Neuraxial anesthesia and analgesia provide several advantages over systemic opioids, including superior analgesia, reduced blood loss and need for transfusion, decreased incidence of graft occlusion, and improved joint mobility following major knee surgery.1-4 New challenges in the management of patients undergoing neuraxial block have arisen over the last(More)

One thousand orthopedic procedures in 924 patients given spinal or epidural anesthesia were prospectively studied to determine the risk of hemorrhagic complications associated with regional anesthesia. A history of excessive bruising or bleeding was elicited in 115 (12%) patients. Preoperative antiplatelet medications were taken by 386 (39%) patients.(More)
Neurologic complications associated with regional anesthesia and pain medicine practice are extremely rare. The ASRA Practice Advisory on Neurologic Complications in Regional Anesthesia and Pain Medicine addresses the etiology, differential diagnosis, prevention, and treatment of these complications. This Advisory does not focus on hemorrhagic and(More)
Although individual cases have been reported in the literature, serious infections of the central nervous system (CNS) such as arachnoiditis, meningitis, and abscess following spinal or epidural anesthesia are rare. However, recent epidemiologic series from Europe suggest that the frequency of infectious complications associated with neuraxial techniques(More)
We describe 49 neurologically asymptomatic patients with persistently increased serum creatine kinase (CK) levels (idiopathic hyperCKemia or IHCK) who were referred to our institution for diagnostic muscle biopsy, including malignant hyperthermia (MH) susceptibility testing between 1979 and 1993. Muscle biopsy samples of the vastus lateralis were obtained(More)
BACKGROUND Desflurane (difluoromethyl 1-fluoro 2,2,2-trifluoroethyl ether) is a new inhalational anesthetic currently under investigation for use in humans. Recently, the authors showed that desflurane is a trigger of malignant hyperthermia (MH) in susceptible swine. To date, there has been no in vivo comparison of the relative ability of inhalational(More)
We prospectively studied 18 male patients undergoing total hip arthroplasty in the lateral decubitus position to determine the effect of injection rate on sensory level and duration of 0.3% hypobaric bupivacaine spinal anesthesia. Patients were randomized into one of two groups according to rate of injection. Dural puncture was performed in the midline at(More)
