- Tethered Cord Syndrome(2022) AMARAL, V. C. G.; CAVALHEIRO, S.; FERREIRA, R. J. R.; MENDONçA, M. L. F. deTethered cord syndrome is characterized by the inability to move the spinal cord during the different stages of life. Clinically, the syndrome is associated with a progressive neurological, orthopedic, and urological deterioration and misplacement of the conus medullaris. Open and closed spinal dysraphisms have a high incidence of tethered spinal cord. Surgical treatment as well as a multimodal intraoperative neurophysiological monitoring protocol, for open and closed spinal dysraphisms, during fetal and postnatal stages is described in detail in this chapter. A mutual understanding between the neurosurgeon, the anesthesiologist, and the neurophysiologist is necessary for minimizing deficits postoperative. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.
- Cervical Spinal Surgery(2022) FERREIRA, R. J. R.; TOSCANO, P.; BORDINI, E. C.; POETSCHER, A. W.One of the main applications of multimodal IONM is cervical spine surgery. Its importance begins in the preoperative period, with the evaluation of the correct positioning of the patient. IONM diagnoses pre-existing neurological deficits and helps to prevent central and peripheral nervous system injuries. In this chapter, IONM in decompressive cervical spine surgery is initially addressed from the surgeon’s perspective, with the relation of the main surgical times. We describe the approach routes in cervical decompression surgeries, their main risks from a neurological point of view, and the tests that should be used in IONM, in a suggested “step by step” protocol. The evidence for the use of IONM, as well as its potential benefits, during cervical spine surgery is discussed. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.
- IOM in Pelvic Floor: Gynecological and Urological Surgeries(2022) FERREIRA, R. J. R.; BORDINI, E. C.; MARTíN-PALOMEQUE, G.; CABAñES-MARTINEZ, L.; LEMOS, N. L. De Barros MoreiraPelvic floor surgeries such as gynecological and urological approaches pose risks of neural injury to structures of the somatic and autonomic nervous systems. Usually, they are radical approaches aiming to cure the patient. Neurological deficits cause an impact on patients’ quality of life due to sexual dysfunction, and urinary and fecal incontinence. Currently, there is a greater concern with their morbidity and attempts to avoid these sequelae. Intraoperative monitoring (IOM) emerges in this scenario to promote neural protection of the somatic and autonomic nervous systems. This chapter discusses the main peculiarities of IOM tests for the somatic and autonomic nervous systems in pelvic floor surgeries (gynecological and urological), considering their performance from a practical point of view. The main limitations and difficulties of IOM of the autonomic nervous system are also addressed. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.
- Spinal Deformity Surgery(2022) FERREIRA, R. J. R.; BORDINI, E. C.; SANTOS, A. C. J. dos; PONTES, R. W. F.; CAVALI, P. T. M.; GONZAGA, T. B.Surgery for spinal deformity, even under the most experienced and skilled teams, brings risk to the neural structures. We discuss the main types of deformity surgeries and their critical steps, according to the surgeon, the anesthesiologist, and the neurophysiologist. The chapter covers our step-by-step protocol for intraoperative neurophysiology monitoring and describes in detail the steps of so-called transpedicular neurophysiological navigation. An algorithm for dealing with alarm signals is offered, based on the authors’ experience and literature review. Finally, we discuss the evidence level of IONM in this type of surgery. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.
- Monitoring in Facial, Neck, and Ear Surgeries(2022) OLIVEIRA, K. M. A. de; Lladó-Carbó E.; FERREIRA, R. J. R.; GONçALVES, M. V. M.; QUINTANILHA, M. A.Intraoperative neurophysiological monitoring in face, neck, and ear surgeries has gradually improved, thanks to technological advances and clinical research. Some techniques, such as spontaneous and stimulated electromyography, are already established. Motor-evoked potential, sensory-evoked potential, electroencephalogram, and laryngeal adductor reflex have been added in the last years to compose a multimodal neurophysiological protocol. The routine use of intraoperative neurophysiological monitoring aims to avoid or minimize neurological sequelae. It is frequent in surgeries with involvement of the facial and vagus nerves and their branches, especially during thyroidectomies and parotidectomies. This chapter encourages the use of multimodal neurophysiological techniques on a larger scale. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.
bookPart NEUROFISIOLOGIA CLÍNICA APLICADA À COLUNA VERTEBRAL: ELETRONEUROMIOGRAFIA, POTENCIAL EVOCADO E MONITORAÇÃO NEUROFISIOLÓGICA INTRAOPERATÓRIA(2016) MAZZALI-VERST, Silvia; FERREIRA, Ricardo José RodriguezbookPart Neurofisiologia intraoperatória(2014) FERREIRA, Ricardo José Rodriguez- Lumbar Interbody Fusion Surgeries: LIFS(2022) FERREIRA, R. J. R.; GONçALVES, M. V. M.; BORDINI, E. C.; CRISTANTE, A. F.The surgical techniques known as LIF (lumbar interbody fusion), LLIF (lateral), ALIF (anterior), OLIF (O), PLIF (posterior), and TLIF (transforaminal) consist of minimally invasive procedures. Numerous advantages are recognized for minimally invasive techniques, but neurological complications arising from this type of surgical procedure have been reported in several studies (Kepler et al., Eur Spine J 20(4):550-556, 2011; Le et al., Spine (Phila Pa 1976) 38(1):E13-E20, 2013; He et al., Zhonghua Yi Xue Za Zhi 94(3):178-181, 2014; Quinn et al., Spine (Phila Pa 1976) 40(12):942-947, 2015; Laratta et al., J Spine Surg 4(2):211-219, 2018; Riley et al., Spine J 18(10):1763-1778, 2018). In this chapter, the authors analyze the anatomical aspects of spinal surgeries through the lateral and anterior approaches (LLIF and ALIF), as well as the main stages of neural risk of each procedure. Furthermore, a step-by-step guide has been prepared, with the main techniques used in IONM to assist the neurophysiologist in these procedures. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.
