INTRODUCTION: The influence of various levels of sedation depth on motor evoked potentials (MEP) reproducibility in youth is still unclear because of a lack of data. We tested the hypothesis that a deeper level of total intravenous anesthesia (TIVA) [bispectral index (BIS) 40 ± 5 compared to 60 ± 5] can affect surgeon-directed MEP and their interpretation in youths. METHODS: All patients received TIVA combined with propofol and remifentanil. TIVA was initially maintained at a BIS level of 60 ± 5. The sedation anesthesia was deepened to BIS level 40 ± 5 before the skin incision. MEP were recorded and interpreted at both BIS levels. The primary endpoint was to evaluate the effect of the depth of sedation on the MEP reproducibility directed and interpreted by the surgical team in each patient separately. The secondary endpoint was to compare the relativized MEP parameters (amplitude and latency) in percentage at various levels of sedation in each patient separately. We planned to enroll 150 patients. Due to the COVID-19 pandemic, we decided to analyze the results of the first 50 patients. RESULTS: The surgical team successfully recorded and interpreted MEP in all 50 enrolled patients in both levels of sedation depth without any clinical doubts. The MEP parameters at BIS level 40 ± 5, proportionally compared with the baseline, were latency 104% (97-110%) and the MEP amplitudes 84.5% (51-109%). CONCLUSION: Preliminary data predict that deeper sedation (BIS 40 ± 5) does not affect the surgical team's interpretation of MEP in youth patients. These results support that surgeon-directed MEP may be an alternative when neurophysiologists are unavailable.

Scoliosis is the most frequent spinal deformity in children. It is defined as a spine deviation of more than 10° in the frontal plane. Neuromuscular scoliosis is associated with a heterogeneous spectrum of muscular or neurological symptoms. Anesthesia and surgery for neuromuscular scoliosis have a higher risk of perioperative complications than for idiopathic scoliosis. However, patients and their relatives report improved quality of life after the surgery. The challenges for the anesthetic team result from the specifics of the anesthesia, the scoliosis surgery itself, or factors associated with neuromuscular disorders. This article includes details of preanesthetic evaluation, intraoperative management, and postoperative care in the intensive care unit from an anesthetic view. In summary, adequate care for patients who have neuromuscular scoliosis requires interdisciplinary cooperation. This comprehensive review covers information about the perioperative management of neuromuscular scoliosis for all healthcare providers who take care of these patients during the perioperative period, with an emphasis on anesthesia management.

BACKGROUND: Congenital cataract, facial dysmorphism, and neuropathy (CCFDN) syndrome is an extremely rare multiorgan disorder. Characteristics include congenital cataracts, facial deformation, extremity deformities, and demyelinating neuropathy. CCFDN syndrome is associated with increased risk during anesthesia including rhabdomyolysis or epileptic seizures. There is a lack of published information about difficult airways in these patients. Difficult airways during intubation represent one of the most dreaded anesthesia complications: A "can not intubate, can not oxygenate" scenario. Presented herein is the first described successful endotracheal intubation of a CCFDN syndrome patient. CASE SUMMARY: We report the anesthetic management of a 13-year-old girl with CCFDN syndrome scheduled for posterior neuromuscular scoliosis correction surgery. The patient suffered from extensive progressive neuromuscular scoliosis with a Cobb angle of 83°. Her limitations included neuropathy and a scoliotic curve. This condition negatively impacted her quality of life. This case reflects the potential anesthetic complications for posterior scoliosis correction and CCFDN syndrome. The challenge for our anesthetic team was the limited amount of data about anesthetic management of this condition. In total, one case report without any data about endotracheal intubation of patients with this condition was available. Endotracheal intubation in our case was uncomplicated. Another focus of our case was the prevention of possible complications associated with this syndrome, including rhabdomyolysis and seizures. Rhabdomyolysis can be triggered by some types of anesthetic agents like suxamethonium or volatile anesthetics, especially in patients with certain types of myopathies. CONCLUSION: Adequate understanding of the anesthetic management of CCFDN syndrome can reduce perioperative complications and improve patient outcome after surgery.

Zhu-Tokita-Takenouchi-Kim (ZTTK) syndrome is an extremely rare multiorgan disorder, first described in 2015. Nowadays, about 50 patients with ZTTK syndrome have been reported, but there are no data about management during anesthesia. ZTTK syndrome patients can be indicated for surgery of musculoskeletal deformations and corrections of cardiovascular or urogenital malformations. This syndrome can be challenging for the anesthetic team based on the clinical manifestation of the syndrome. Because there are no recommendations for the management of these patients, anesthesiologists have to study typical symptoms, anatomy and possible expected changes in pathophysiology in perioperative period. One of the most dreaded anesthetic complications, the scenario "can not intubate, can not ventilate" could occur in these patients. The goal of this publication is to show options for anesthetic and perioperative management of this new rare syndrome with no published studies about management and approach in the perioperative period. The anesthetic team should choose the safest available approach. We present the first case report of anesthesia of a patient with ZTTK syndrome, a 7-year-old boy indicated for posterior neuromuscular scoliosis correction and fusion. This case describes the author's experiences with anesthetic management and mentions possible early postoperative complications. Adequate understanding of this syndrome can reduce perioperative complications and improve patient outcomes after surgery.

Intraoperační sledování evokovaných potenciálů představuje v současnosti významnou neurofyziologickou metodu používanou v rámci operačních výkonů, u kterých hrozí riziko narušení funkční integrity CNS. Jednou z nejvýznamnějších monitorovacích modalit jsou transkraniální motorické evokované potenciály (MEP), které mohou být efektivně sledovány proškoleným operačním týmem pod dohledem neurofyziologa. Pro správný neuromonitoring je potřeba efektivní spolupráce mezi operačním týmem, anesteziologickým týmem a neurofyziologem. Cílem tohoto článku je vytvořit ucelený přehled všech potenciálních faktorů, jež mohou ovlivnit výbavnost MEP v intraoperačním období. Autoři se zaměřují nejen na vliv jednotlivých léčiv používaných v rámci anestezie, ale i na samotnou formu anestezie či nefarmakologické faktory s možným vlivem na výbavnost MEP. Tento přehledový článek poskytuje základní informace všem, kteří se podílejí na perioperační péči o pacienty podstupující výkony s monitorací MEP, a může tak usnadnit spolupráci a zefektivnit komunikaci napříč zainteresovanými obory.
Intraoperative evoked potentials monitoring is an essential neurophysiological modality used in surgeries with a risk of CNS functional integrity damage. Transcranial motor evoked potentials (MEPs) are one of the most important modalities. Trained surgeons can effectively monitor MEPs under the supervision of a neurophysiologist. Effective cooperation among all operating team members, anaesthesiologists, and neurophysiologist is essential for proper neuromonitoring. The aim of this article is to comprehensively summarize all possible factors that can affect the quality of intraoperative MEPs monitoring. The authors focus on the effect of anaesthetic drugs and anaesthetic management, including anaesthesia maintenance or non-pharmacological factors, which can affect the MEPs’ reproducibility. This review provides essential information to all members of a perioperative team that take care for patients during surgery with MEPs monitoring. This information can facilitate cooperation and streamline communication across all related disciplines.
