A case of paradoxical presentation of a postural postdural puncture headache after combined spinal-epidural anesthesia.

We report a case of paradoxical presentation of a postural postdural puncture headache secondary to dural puncture with a 25-gauge Whitacre needle for combined spinal-epidural anesthesia. This 27-year-old female patient presented to the emergency department with elevated blood pressure and a global headache 9 days after administration of epidural anesthesia for a spontaneous vaginal delivery after an uncomplicated pregnancy. The patient reported that the headache was more intense when lying down and immediately improved when she sat or stood up from a recumbent position.

Triple-blind randomized clinical trial of time until sensory change using 1.5% mepivacaine with epinephrine, 0.5% bupivacaine, or an equal mixture of both for infraclavicular block.

Background And Objectives: Practitioners mix faster-onset, intermediate-duration local anesthetics (LAs) with slower-onset, long-duration LAs to get fast peripheral nerve block (PNB) onset and long duration. We hypothesized that 1.5% mepivacaine (with epinephrine) (mepivacaine) or 1.

General anesthesia for ophthalmic surgery.

Skillful anesthetic management is integral to optimal outcomes after ophthalmic surgery. Although the majority of ophthalmic operations in the United States are performed with local anesthetic techniques, nonetheless general anesthesia may be either necessary or advisable in several challenging circumstances. Ophthalmic patients are often at the extremes of age, and not uncommonly have extensive associated systemic or metabolic diseases.
