Preliminary Study on Application of Combined Monitoring of Neuroelectrophysiology-Intracranial Pressure-Cerebral Perfusion Pressure in Craniotomy for Intracranial Aneurysm Clipping: An Anatomical and Clinical Study

SUMMARY: Intracranial aneurysm is a common cerebrovascular disease with high mortality. Neurosurgical clipping for the treatment of intracranial aneurysms can easily lead to serious postoperative complications. Studies have shown that intraoperative monitoring of the degree of cerebral ischemia is extremely important to ensure the safety of operation and improve the prognosis of patients. Aim of this study was to probe the application value of combined monitoring of intraoperative neurophysiological monitoring (IONM)-intracranial pressure (ICP)-cerebral perfusion pressure (CPP) in craniotomy clipping of intracranial aneurysms. From January 2020 to December 2022, 126 patients in our hospital with intracranial aneurysms who underwent neurosurgical clipping were randomly divided into two groups. One group received IONM monitoring during neurosurgical clipping (control group, n=63), and the other group received IONM-ICP-CPP monitoring during neurosurgical clipping (monitoring group, n=63). The aneurysm clipping and new neurological deficits at 1 day after operation were compared between the two groups. Glasgow coma scale (GCS) score and national institutes of health stroke scale (NIHSS) score were compared before operation, at 1 day and 3 months after operation. Glasgow outcome scale (GOS) and modified Rankin scale (mRS) were compared at 3 months after operation. All aneurysms were clipped completely. Rate of new neurological deficit at 1 day after operation in monitoring group was 3.17 % (2/63), which was markedly lower than that in control group of 11.11 % (7/30) (P0.05). Combined monitoring of IONM-ICP-CPP can monitor the cerebral blood flow of patients in real time during neurosurgical clipping, according to the monitoring results, timely intervention measures can improve the consciousness state of patients in early postoperative period and reduce the occurrence of early postoperative neurological deficits.

El aneurisma intracraneal es una enfermedad cerebrovascular común con alta mortalidad. El clipaje neuroquirúrgico para el tratamiento de aneurismas intracraneales puede provocar complicaciones posoperatorias graves. Los estudios han demostrado que la monitorización intraoperatoria del grado de isquemia cerebral es extremadamente importante para garantizar la seguridad de la operación y mejorar el pronóstico de los pacientes. El objetivo de este estudio fue probar el valor de la aplicación de la monitorización combinada de la monitorización neurofisiológica intraoperatoria (IONM), la presión intracraneal (PIC) y la presión de perfusión cerebral (CPP) en el clipaje de craneotomía de aneurismas intracraneales. Desde enero de 2020 hasta diciembre de 2022, 126 pacientes de nuestro hospital con aneurismas intracraneales que se sometieron a clipaje neuroquirúrgico se dividieron aleatoriamente en dos grupos. Un grupo recibió monitorización IONM durante el clipaje neuroquirúrgico (grupo de control, n=63) y el otro grupo recibió monitorización IONM-ICP-CPP durante el clipaje neuroquirúrgico (grupo de monitorización, n=63). Se compararon entre los dos grupos el recorte del aneurisma y los nuevos déficits neurológicos un día después de la operación. La puntuación de la escala de coma de Glasgow (GCS) y la puntuación de la escala de accidentes cerebrovasculares de los institutos nacionales de salud (NIHSS) se compararon antes de la operación, 1 día y 3 meses después de la operación. La escala de resultados de Glasgow (GOS) y la escala de Rankin modificada (mRS) se compararon 3 meses después de la operación. Todos los aneurismas fueron cortados por completo. La tasa de nuevo déficit neurológico 1 día después de la operación en el grupo de seguimiento fue del 3,17 % (2/63), que fue notablemente inferior a la del grupo de control del 11,11 % (7/30) (P 0,05). La monitorización combinada de IONM-ICP-CPP puede controlar el flujo sanguíneo cerebral de los pacientes en tiempo real durante el corte neuroquirúrgico; de acuerdo con los resultados de la monitorización, las medidas de intervención oportunas pueden mejorar el estado de conciencia de los pacientes en el período postoperatorio temprano y reducir la aparición de problemas postoperatorios tempranos y déficits neurológicos.

Application of analgesia and sedation under BIS monitoring combined with hydraulic coupling intracranial pressure monitoring in severe craniocerebral injury / 中华危重病急救医学

OBJECTIVE@#To investigate the clinical value of analgesia and sedation under bispectral index (BIS) monitoring combined with hydraulic coupled intracranial pressure (ICP) monitoring in severe craniocerebral injury (sTBI).@*METHODS@#(1) A prospective self-controlled parallel control study was conducted. A total of 32 patients with sTBI after craniotomy admitted to the intensive care unit (ICU) of the First People's Hospital of Huzhou from December 2020 to July 2021 were selected as the research objects. ICP was monitored by Codman monitoring system and hydraulically coupled monitoring system, and the difference and correlation between them were compared. (2) A prospective randomized controlled study was conducted. A total of 108 sTBI patients admitted to the ICU of the First People's Hospital of Huzhou from August 2021 to August 2022 were selected patients were divided into 3 groups according to the random number table method. All patients were given routine treatment after brain surgery. On this basis, the ICP values of the patients in group A (35 cases) were monitored by Codman monitoring system, the ICP values of the patients in group B (40 cases) were monitored by hydraulic coupling monitoring system, and the ICP values of the patients in group C (33 cases) were monitored combined with hydraulic coupling monitoring system, and the analgesia and sedation were guided by BIS. The ICP after treatment, cerebrospinal fluid drainage time, ICP monitoring time, ICU stay time, complications and Glasgow outcome score (GOS) at 6 months after surgery were compared among the 3 groups. In addition, patients in group B and group C were further grouped according to the waveforms. If P1 = P2 wave or P2 and P3 wave were low, they were classified as compensatory group. If the round wave or P2 > P1 wave was defined as decompensated group, the GOS scores of the two groups at 6 months after operation were compared.@*RESULTS@#(1) There was no significant difference in ICP values measured by Codman monitoring system and hydraulic coupling monitoring system in the same patient (mmHg: 11.94±1.76 vs. 11.88±1.90, t = 0.150, P = 0.882; 1 mmHg≈0.133 kPa). Blan-altman analysis showed that the 95% consistency limit (95%LoA) of ICP values measured by the two methods was -4.55 to 4.68 mmHg, and all points fell within 95%LoA, indicating that the two methods had a good correlation. (2) There were no significant differences in cerebrospinal fluid drainage time, ICP monitoring time, ICU stay time, and incidence of complications such as intracranial infection, intracranial rebleeding, traumatic hydrocephalus, cerebrospinal fluid leakage, and accidental extubation among the 3 groups of sTBI patients (P > 0.05 or P > 0.017). The ICP value of group C after treatment was significantly lower than that of group A and group B (mmHg: 20.94±2.37 vs. 25.86±3.15, 26.40±3.09, all P < 0.05), the incidence of pulmonary infection (9.1% vs. 45.7%, 42.5%), seizure (3.0% vs. 31.4%, 30.0%), reoperation (3.0% vs. 31.4%, 40.0%), and poor prognosis 6 months after operation (33.3% vs. 65.7%, 65.0%) were significantly lower than those in group A and group B (all P < 0.017). According to the hydraulic coupling waveform, GOS scores of 35 patients in the compensated group were significantly higher than those of 38 patients in the decompensated group 6 months after operation (4.03±1.18 vs. 2.39±1.50, t = 5.153, P < 0.001).@*CONCLUSIONS@#The hydraulic coupled intracranial pressure monitoring system has good accuracy and consistency in measuring ICP value, and it can better display ICP waveform changes than the traditional ICP monitoring method, and has better prediction value for prognosis evaluation, which can replace Codman monitoring to accurately guide clinical work. In addition, analgesia and sedation under BIS monitoring combined with hydraulic coupled ICP monitoring can effectively reduce ICP, reduce the incidence of complications, and improve the prognosis, which has high clinical application value.

Wearable devices: Perspectives on assessing and monitoring human physiological status / 生物医学工程学杂志

This review article aims to explore the major challenges that the healthcare system is currently facing and propose a new paradigm shift that harnesses the potential of wearable devices and novel theoretical frameworks on health and disease. Lifestyle-induced diseases currently account for a significant portion of all healthcare spending, with this proportion projected to increase with population aging. Wearable devices have emerged as a key technology for implementing large-scale healthcare systems focused on disease prevention and management. Advancements in miniaturized sensors, system integration, the Internet of Things, artificial intelligence, 5G, and other technologies have enabled wearable devices to perform high-quality measurements comparable to medical devices. Through various physical, chemical, and biological sensors, wearable devices can continuously monitor physiological status information in a non-invasive or minimally invasive way, including electrocardiography, electroencephalography, respiration, blood oxygen, blood pressure, blood glucose, activity, and more. Furthermore, by combining concepts and methods from complex systems and nonlinear dynamics, we developed a novel theory of continuous dynamic physiological signal analysis-dynamical complexity. The results of dynamic signal analyses can provide crucial information for disease prevention, diagnosis, treatment, and management. Wearable devices can also serve as an important bridge connecting doctors and patients by tracking, storing, and sharing patient data with medical institutions, enabling remote or real-time health assessments of patients, and providing a basis for precision medicine and personalized treatment. Wearable devices have a promising future in the healthcare field and will be an important driving force for the transformation of the healthcare system, while also improving the health experience for individuals.

The aging population and the increasing prevalence of chronic diseases in the elderly have brought a significant economic burden to families and society. The non-invasive wearable sensing system can continuously and real-time monitor important physiological signs of the human body and evaluate health status. In addition, it can provide efficient and convenient information feedback, thereby reducing the health risks caused by chronic diseases in the elderly. A wearable system for detecting physiological and behavioral signals was developed in this study. We explored the design of flexible wearable sensing technology and its application in sensing systems. The wearable system included smart hats, smart clothes, smart gloves, and smart insoles, achieving long-term continuous monitoring of physiological and motion signals. The performance of the system was verified, and the new sensing system was compared with commercial equipment. The evaluation results demonstrated that the proposed system presented a comparable performance with the existing system. In summary, the proposed flexible sensor system provides an accurate, detachable, expandable, user-friendly and comfortable solution for physiological and motion signal monitoring. It is expected to be used in remote healthcare monitoring and provide personalized information monitoring, disease prediction, and diagnosis for doctors/patients.

Función pulmonar: medición continua de la saturación del pulso arterial de oxígeno: propuesta para interpretación / Continuous measurement of oxygen arterial pulse saturation: an interpretation proposal

La medición continua de la saturación de pulso arterial de oxígeno (SpO2) es un método no invasivo, confiable y seguro. El consolidado permite obtener valores promedio de SpO2 y frecuencia cardiaca, gráficos y valores acumulados, rangos de valores de SpO2, que permiten definir si existe o no alguna alteración. Los avances tecnológicos han dado paso a la fabricación de equipos con alta exactitud de las mediciones, mediante algoritmos matemáticos que filtran los artefactos debido a movimientos y/o hipoperfusión. La ventaja, es una mayor precisión para determinar estados de hipoxemia en distintas situaciones clínicas. Las principales indicaciones en pediatría son la determinación de hipoxemia y titulación de oxígeno en niños con enfermedades que comprometen el sistema respiratorio, especialmente displasia broncopulmonar. También se usa como screening para apneas obstructivas del sueño en rango moderado a severo en situaciones en que no es posible realizar poligrafía o polisomnografía, dado la facilidad con la que se puede realizar la medición continua de SpO2 en domicilio u hospitalizado. En este artículo se describen características importantes del procedimiento, y se propone un esquema para ordenar su interpretación.

Continuous measurement of arterial oxygen saturation by pulse oximetry (SpO2) is a non-invasive, reliable, and safe method. The consolidated allows obtaining average values of SpO2 and heart rate, graphs and accumulated values, ranges of SpO2 values, which allow defining whether or not there is any alteration. Technological advances have given way to the manufacture of equipment with high measurement accuracy, using mathematical algorithms that filter artifacts due to movements and/or hypoperfusion. The main indications are the diagnosis of hypoxemia and titration of oxygen requirements in patients with chronic lung damage and other diseases that compromise the respiratory system. Also, it is used as screening of moderate to severe obstructive apneas when other sleep studies, such as polysomnography or polygraphy, are not available. It can be done at home or hospitalized. This article describes important characteristics of the procedure, and a scheme is proposed to order its interpretation.

Noninvasive hemoglobin monitoring in clinical trials: a systematic review and meta-analysis / Monitorização não invasiva da hemoglobina em ensaios clínicos: uma revisão sistemática e metanálise

Abstract Background and objectives: The measurement of hemoglobin concentration (Hb) by co-oximetry is an innovative technique that offers efficiency and agility in the processing of information regarding the measurement of Hb obtained through continuous, non-invasive and rapid monitoring. Because of this attribute, it avoids unnecessary exposures of the patient to invasive procedures by allowing a reduction in the number of blood samples for evaluation and other unnecessary therapies. It also helps to make decisions about the need for transfusion and how to handle it. The objective of this study is to compare the performance offered to obtain Hb values between the Masimo Corporation (Irvine, CA, USA) instrument and the standard gold tool (laboratory examination). Contents: The study corresponds to a systematic review followed by meta-analysis, which included fully registered full-text clinical trials published from 1990 to 2018. PubMed, Cochrane, Medline, Embase and Web of Science databases were investigated. The mean overall difference found between the non-invasive and invasive methods of hemoglobin monitoring was 0.23 (95% CI -0.16, 0.62), that is, it did not present statistical significance (p = 0.250). The results of the analysis of heterogeneity within and between the studies indicated high levels of inconsistency (Q = 461.63, p < 0.0001, I2 = 98%), method for Hb values. Conclusions: Although the mean difference between noninvasive measurements of Hb and the gold standard method is small, the co-oximeter can be used as a non-invasive "trend" monitor in detecting unexpected responses at Hb levels.

Resumo Justificativa: A medida da concentração de hemoglobina (Hb)por co-oximetria é uma técnica inovadora que oferece eficiência e agilidade no processamento das informações referentes à medida da concentração de hemoglobina obtida por meio de monitorização contínua, não-invasiva e rápida. Por conta desse atributo, evita exposições desnecessárias do paciente a procedimentos invasivos ao possibilitar redução da quantidade de amostras sanguíneas para avaliação e de outras terapêuticas desnecessárias. Além disso, auxilia a tomada de decisões quanto à necessidade de transfusão e quanto ao manejo da mesma. Objetivo: Comparar o desempenho oferecido para a obtenção dos valores de concentração de hemoglobina entre medida não invasiva da Hb e a ferramenta padrão ouro (exame laboratorial). Conteúdo: O estudo corresponde a uma revisão sistemática seguida de metanálise que incluiu ensaios clínicos devidamente registrados com texto completo, publicados a partir de 1990 até 2018. Foram investigadas as bases de dados PubMed, Cochrane, Medline, Embase e Web Of Science. A diferença média global encontrada entre os métodos não invasivo e invasivo de monitorização da hemoglobina foi de 0,23 (95% IC -0,16; 0,62), ou seja, não apresentou significância estatística (p = 0,250). Os resultados da análise de heterogeneidade dentro e entre os estudos, apontou níveis elevados de inconsistência (Q = 461,63, p< 0,0001, I2 = 98%). Conclusão: Embora a diferença média entre as medidas não invasivas da Hb e o método padrão ouro sejam pequenas, o co-oxímetro pode ser utilizado como um monitor não invasivo de "tendência" na detecção de alterações inesperadas nos níveis de Hb.

Monitorización cardio respiratoria domiciliaria en lactantes / Home respiratory cardio monitoring in infants

Home cardio-respiratory monitoring began over 40 years ago with the aim of preventing sudden infant death. Although it has been shown that monitoring does not meet this objective, its prescription has been maintained in various clinical situations and with very different criteria. Consensus on the subject has not been able to define precisely the type of monitoring or the time required for different diseases. Among the diseases that still consider the indication of cardio-respiratory monitoring at home are: persistent apnea of prematurity, high-risk BRUE (Brief Resolved Unexplained Events), neurological or metabolic diseases with compromise of the respiratory center, convulsive cough, pathologic gastroesophageal reflux and technology-dependent patients (high flow nasal cannula (CNAF), noninvasive ventilation (NIV), invasive mechanical ventilation (IMV) to tracheostomy, and others). A review is presented on the development of cardio-respiratory monitoring at home, highlighting the true usefulness of this technology with a general proposal, which must be evaluated on a case-by-case basis and always taking into account the conditions that must be met to perform adequate monitoring and useful.

La monitorización cardio-respiratoria en domicilio se inició hace más de 40 años con el objetivo de prevenir la muerte súbita del lactante. Aun cuando se ha demostrado que la monitorización no cumple este objetivo, se ha mantenido su prescripción en diversas situaciones clínicas y con criterios muy diversos. Consensos acerca del tema no han llegado a definir con precisión el tipo de monitorización ni el tiempo requerido para distintas enfermedades. Dentro de las enfermedades que todavía consideran la indicación de monitorización cardio-respiratoria en domicilio se encuentran: apnea persistente del prematuro, BRUE (episodio breve resuelto inexplicado) de alto riesgo, enfermedades neurológicas o metabólicas con compromiso del centro respiratorio, tos convulsiva, reflujo gastroesofágico patológico y pacientes dependientes de tecnología (cánula nasal de alto flujo (CNAF), ventilación no invasiva (VNI), ventilación mecánica invasiva (VMI) a traqueostomía, y otros). Se presenta una revisión sobre el desarrollo de la monitorización cardio-respiratoria en domicilio, resaltando la verdadera utilidad que tendría esta tecnología con una propuesta general, que debe evaluarse caso a caso y siempre teniendo en cuenta las condiciones que deben cumplirse para realizar una monitorización adecuada y útil.

OBJECTIVE@#To explore the feasibility of remote monitoring of neonatal jaundice in newborns with ABO hemolytic disease.@*METHODS@#Forty six neonates of gestational age >35 weeks with ABO hemolytic disease admitted to Women's Hospital, Zhejiang University School of Medicine from January 20th, 2020 to February 29th, 2020 were enrolled in the study (study group). The newborns were followed up at home after discharge, the transcutaneous bilirubin (TCB) levels were measured by parents using the provided device and the results were sent to the doctor by smart phone using the installed APP. Fifty six newborns with ABO hemolytic disease admitted in 2018 who received conventional outpatient follow-up after discharge served as the control group. The demographic characteristics, total serum bilirubin (TSB) level during hospitalization, number of outpatient visit and rate of re-admission due to rebound hyperbilirubinemia were compared between the two groups.@*RESULTS@#There were no significant differences between the two groups in gestational age, birth weight, delivery mode, gender, length of the first hospitalization, TSB level before phototherapy and before discharge, and the managements during the first hospitalization (all @*CONCLUSIONS@#The remote follow-up for neonatal jaundice at home can effectively reduce the number of outpatient visits without increasing the risk of readmission and severe neonatal hyperbilirubinemia for newborns with ABO hemolytic disease.

The use of the Modified Early Obstetric Warning System (MEOWS) in women after pregnancies: a descriptive study / Aplicação do Modified Early Obstetric Warning System (MEOWS) em mulheres após gestações: um estudo descritivo

Abstract Objectives: to evaluate the modified early obstetric warning system (MEOWS) in women after pregnancies in a tertiary hospital in Brazil. Methods: a descriptive study was conducted with 705 hospitalized women. Vital signs (systolic and diastolic blood pressure, heart rate, respiratory rate, temperature) and lochia were registered on medical records and transcribed into the MEOWS chart of physiological parameters. On this graphic chart, yellow alerts were used to present moderate abnormalities in vital signs, while severe abnormalities were presented in red. The presence of at least one red alert or two yellow alerts were triggered to indicate the need for medical evaluation. Results: although abnormalities were found in the physiological parameters of 49.8% of the women identified from MEOWS triggers, medical evaluation was only requested for three patients (0.8%). Conclusions: in a retrospective application of the use of MEOWS showed a significant number of patients had triggered in which the nursing team did not recognize 99.2% of cases. This finding could be attributed to the fact that MEOWS has not been yet adopted in this service as part of the nursing care. The application of this tool would result in a better care because critical situations would be recognized and corrected quickly, avoiding unfavorable outcomes.

Resumo Objetivos: avaliar o modified early obstetric warning system (MEOWS) em mulheres após gestações, em um hospital terciário do Brasil. Métodos: foi realizado um estudo descritivo incluindo 705 mulheres internadas. Os sinais vitais (pressão arterial sistólica e diastólica, frequência cardíaca, frequência respiratória, temperatura) e lóquios, registrados no prontuário, foram transcritos para o gráfico de parâmetros fisiológicos do MEOWS. Neste gráfico, anormalidades moderadas nos sinais vitais eram sinalizadas por alertas amarelos, enquanto anormalidades graves eram sina-lizadas em vermelho. A presença de, pelo menos, um alerta vermelho ou dois alertas amarelos foi chamada de eventos gatilho, indicando necessidade de avaliação médica. Resultados: dentre as mulheres estudadas, 49,8% apresentaram anormalidades nos parâmetros fisiológicos, através da identificação de eventos gatilho no MEOWS, porém avaliação médica foi solicitada para apenas três pacientes, resultando num percentual de 0,8%. Conclusões: a utilização do MEOWS, de forma retrospectiva, evidenciou uma quantidade significativa de pacientes apresentando eventos gatilho, os quais não foram reconhecidos pela equipe de enfermagem em 99,2% dos casos. Este achado pode ser atribuído ao fato de o MEOWS ainda não ser adotado no serviço como parte da rotina dos cuidados de enfermagem. A aplicação dessa ferramenta resultaria numa assistência melhor, pois situações críticas seriam reconhecidas e corrigidas com maior precocidade, evitando desfechos desfavoráveis.
