The feasibility and reliability of combined use transcranial direct cortical motor evoked potential (MEP) monitoring during unruptured aneurysm surgery were evaluated. Forty-eight patients with cerebral aneurysms underwent craniotomy neck clipping accompanied by muscle MEP monitoring. MEPs elicited successfully electrical stimulation in all patients. Direct 44 Reduction amplitude to less than 50% baseline was considered significant. No postoperative paresis occurred 39 whom remained...
In neurosurgical procedures that may cause visual impairment in the intraoperative period, monitoring of flash evoked potential (VEP) is clinically used to evaluate function. Patients are unconscious during surgery under general anesthesia, making VEP useful as it can objectively The stimulus input retina transmitted optic nerve, chiasm, tract, lateral geniculate body, radiation (geniculocalcarine tract), and cortical area, waveform recorded from occipital region. Intraoperative allows...
Monitoring the intraoperative motor evoked potentials (MEPs) in pediatric craniotomy is challenging because of its low detection rate, which makes it unreliable. Tetanic stimulation peripheral nerves extremities and pudendal prior to transcranial electrical (TES) or direct cortical (DCS) amplifies MEPs. The authors investigated effects MEP amplification following tetanic median tibial nerve patients undergoing craniotomy.
In Brief Study Design. A prospective research. Objective. Compare the reliability of post-tetanic motor-evoked potential (p-MEP) monitoring in detection motor injury during spinal surgery with that conventional MEP (c-MEP). Summary Background Data. Myogenic MEPs are sensitive to suppression by anesthetics and neuromuscular blockade. Recently, we reported a new technique for recording, called “p-MEP” which amplitude can be enlarged tetanic stimulation peripheral nerve before transcranial...
Patient movement in response to transcranial stimulation during monitoring of myogenic motor-evoked potentials (MEPs) may interfere with surgery. We recently reported a new technique augment the amplitudes MEPs, called "post-tetanic MEPs (p-MEPs)," which tetanic peripheral nerve was applied prior stimulation. conducted present study determine an appropriate level neuromuscular blockade p-MEPs focus on patient movement.In 15 patients under propofol/fentanyl anesthesia, conventional (c-MEPs)...
Intraocular pressure (IOP) has been shown to increase during prone spine surgery. Although propofol and sevoflurane have widely used such surgery, there no data compare the IOP changes under anesthesia. The present study was therefore conducted investigate anesthesia surgery.After institutional approval informed consent, 24 patients undergoing surgery were studied. Patients randomly allocated 1 of 2 groups: or group. Propofol administered maintain bispectral index between 40 60. measured...
Spinal cord ischemic injury is the most devastating sequela of descending and thoracoabdominal aortic surgery. Motor-evoked potentials (MEPs) have been used to intraoperatively assess motor tract function, but it remains unclear whether MEP monitoring can decrease incidence postoperative deficits. Therefore, we reviewed multicenter medical records patients who had undergone repair (both open surgery endovascular repair) association with deficits.Patients included in study underwent or at 12...
Recently, we reported a new technique to augment motor-evoked potentials (MEPs) under general anesthesia, posttetanic MEP (p-MEP), in which tetanic stimulation of the peripheral nerve before transcranial enlarged amplitudes MEPs from muscle innervated by subjected stimulation. In present study, tested whether left tibial can also muscles are not stimulation.Thirty patients undergoing spinal surgery propofol-fentanyl anesthesia with partial neuromuscular blockade were examined. For...
We present a case with abnormal findings of initial motor-evoked potential (MEP) in the left upper limb after prone positioning during lumbar spine surgery.
Reportedly, tetanic stimulation prior to transcranial electrical (TES) facilitates elicitation of motor evoked potentials (MEPs) by a mechanism involving increased corticomotoneuronal excitability in response somatosensory input. However, the posttetanic MEP following pure sensory nerve has never been reported. Furthermore, no previous reports have described MEPs pediatric patients. The aim this study was investigate efficacy neurosurgery patients and compare effects on after branch pudendal...
