Development and reliability and validity testing of the assessment scale for patients with persistent vegetative state or minimally conscious state discharge from the anesthesia recovery room / 中国实用护理杂志

Objective:To develop and test the reliability and validity of the assessment scale for patients with persistent vegetative state (PVS) or minimally conscious state (MCS) discharge from the anesthesia recovery room after operation.Methods:From September 2018 to October 2020, three dimensions and 17 item pools were determined through literature review and discussion among the project members. Two rounds of expert consultation were conducted to determine the respiratory (R), circulatory (C), oxygenation (O), bispectral index (B) and neuromuscular monitoring (N) scale (RCOBN scale), the reliability and validity were tested. 87 patients with PVS or MCS after operation Affiliated Sichuan Bayi Rehabilitation Center of Chengdu University of Traditional Chinese Medicine were selected to verify the effectiveness.Results:In the first round, 23 questionnaires were distributed. The total score of experts was 50 ± 3, F=9.24, CV were 0.00-0.43. The Cronbach α coefficient of each dimension was 0.782-0.846, and the Cronbach α coefficient of the total scale was 0.813. In the second round, 10 questionnaires were distributed. The item-level content validity index was 0.7-1.0, the probability of random consistency ( Pc) was 0.001-0.117, the adjusted kappa value ( k*) was 0.567-1.000, and the sum of the index scores corresponding to k* > 0.74 was 8. The scale-level content validity index of the overall consistency was 0.87. The ratio of patients transferred out of PACU by two rounds of evaluation method was 100 : 96.55, and the difference was not statistically significant ( χ2=3.05, P>0.05). The time of the first round of assessment was significantly longer than that of the second round, which were (197 ± 52) s and (58 ± 14) s respectively. The difference was statistically significant ( t=26.52, P < 0.01). Conclusions:The RCOBN scale has high reliability and validity. It can be used as an assessment scale for patients with PVS or MCS to transfer out of PACU after surgery, and those with a total score of 8 can be transferred out of PACU.

Effects of acupuncture on nutritional status in patients in a persistent vegetative state: a prospective randomized controlled study / 针灸推拿医学（英文版）

Objective: To explore the effects of acupuncture on nutritional status in patients in a persistent vegetative state. Methods: A prospective randomized controlled trial was designed. A total of 66 patients in a persistent vegetative state were randomized into a control group and an observation group, with 33 cases in each group. The control group was given conventional treatment plus enteral nutrition support. The observation group was treated with additional Tiao Shen Jian Pi acupuncture therapy (acupuncture for spirit-regulating and spleen-invigorating) based on the same interventions in the control group. Both groups were treated for 8 weeks. The levels of total protein (TP), prealbumin (PA), albumin (Alb), and hemoglobin (Hb) were measured before and after treatment. The upper arm circumference and skinfold thickness of triceps brachii were measured. And the intestinal flora and fecal short-chain fatty acids contents were determined.Results: After treatment, the levels of TP, PA, Alb, and Hb in the control group were decreased (P<0.05), while in the observation group, compared with those before treatment, the levels of TP, PA, Alb, and Hb had no statistical differences (P>0.05), and the levels were all higher than those in the control group (P<0.05). The upper arm circumference and skinfold thickness of triceps brachii in both groups decreased (P<0.05), and the values of these two items in the observation group were higher than those in the control group (P<0.05). In the control group, the contents of Bifidobacterium and Lactobacillus in feces decreased (P<0.05), and the content of Enterococcus increased (P<0.05). In the observation group, the contents of Bifidobacterium and Lactobacillus in feces increased (P<0.05), and the content of Enterococcus decreased (P<0.05). The differences between the two groups were statistically significant (P<0.05). In the control group, the total content of fecal short-chain fatty acids and the contents of acetic acid and butyric acid in feces decreased (P<0.05). In the observation group, the total content of fecal short-chain fatty acids and the contents of acetic acid and butyric acid in feces increased (P<0.05) and were all higher than those in the control group (P<0.05). Conclusion: Acupuncture can improve nutrition-related blood indicators in patients in a persistent vegetative state and delay the decrease of upper arm circumference and skinfold thickness of triceps brachii, which may be related to the regulation of intestinal flora and fecal short-chain fatty acids contents.

¿Es proporcionado suspender la nutrición e hidratación artificial en pacientes con pronóstico incierto? Perspectiva nutricional y bioética

para llevar a cabo esta investigación, se revisó la literatura sobre el caso de Terri Schiavo, paciente que se encontraba en estado vegetativo persistente y quien falleció luego de dos semanas, después de que se le suspendiera su alimentación e hidratación; se validó su diagnóstico y se indagó si fue una paciente terminal, así como también se verificó la evidencia disponible, en relación con la hidratación y nutrición artificial en este tipo de pacientes, para determinar la concordancia de estas medidas. Esta información fue analizada desde la perspectiva nutricional y bioética; en la búsqueda bibliográfica se consultaron las bases de datos Scopus, Scielo y PubMed, con los criterios de búsqueda nutrición e hidratación artificial en pacientes terminales y de pronóstico incierto. Estos hallazgos fueron analizados con el modelo de proporcionalidad terapéutica de Calipari. Por lo anterior, se determinó que la nutrición e hidratación artificial configuraban tratamientos de carácter obligatorio u optativo para Terri. Sin embargo, pese a que no existe información concluyente sobre la nutrición e hidratación artificial en pacientes terminales, ni de pronóstico incierto, se recomienda la evaluación caso a caso de parte del equipo médico, para determinar la proporcionalidad de estos procedimientos en conjunto con el paciente y su familia. Cabe resaltar que son necesarios más estudios para proporcionar mejor evidencia que permita contar con elementos objetivos para una mejor toma de decisiones.

to carry out this research, the literature was reviewed on the case of Terri Schiavo, a patient who was in a persistent vegetative state and who died after two weeks, after her nutrition and hydration were suspended; her diagnosis was validated, and it was investigated whether she was a terminal patient, as well as the available evidence, was verified, in relation to artificial hydration and nutrition in this type of patients to determine the concordance of these measures. This information was analyzed from the nutritional and bioethical perspective; in the bibliographic search, the Scopus, Scielo, and PubMed databases were consulted with the search criteria nutrition and artificial hydration in terminal patients and patients with uncertain prognosis; these findings were analyzed with Calipari's therapeutic proportionality model. Therefore, it was determined that artificial nutrition and hydration are mandatory or optional treatments for Terri. However, there is no conclusive information on artificial nutrition and hydration in terminally ill patients, nor is the prognosis uncertain, and a case-by-case evaluation by the medical team is recommended to determine the proportionality of artificial nutrition and hydration, together with the patient and family. It should be emphasized that more studies are needed to provide better evidence to provide objective elements for better decision-making.

Para realizar esta pesquisa, foi revisada a literatura sobre o caso de Terri Schiavo, paciente que se encontrava em estado vegetativo persistente e que faleceu após duas semanas depois de sua alimentação e hidratação terem sido suspensas. Foi avaliado seu diagnóstico e questionado se foi uma paciente terminal, bem como verificada a evidência disponível quanto à hidratação e à nutrição artificiais nesse tipo de pacientes para determinar a concordância dessas medidas. Essa informação foi analisada sob a perspectiva nutricional e bioética; na busca bibliográfica, foram consultadas as bases de dados Scopus, SciELO e PubMed, com os critérios de busca "nutrição e hidratação artificiais em pacientes terminais e de prognóstico incerto". Esses achados foram analisados com o modelo de proporcionalidade terapêutica de Calipari. Assim, foi determinado que a nutrição e a hidratação artificiais configuram tratamentos de caráter obrigatório ou opcional para Terri. Contudo, não existe informação conclusiva sobre a nutrição e a hidratação artificiais em pacientes terminais, nem em pacientes com prognóstico incerto. É recomendada a avaliação por parte da equipe médica caso a caso para determinar a adequação da nutrição e da hidratação artificiais em conjunto com o paciente e sua família. Cabe ressaltar que mais estudos são necessários para proporcionar melhor evidência que permita contar com elementos objetivos para uma melhor tomada de decisões.

Xiao's "xingnaofusu" needling for regaining consciousness and the influence on width of the third ventricle in patients with persistent vegetative state / 针刺研究

OBJECTIVE: To observe the influence of Xiao's "xingnaofusu" needling (the technique for resuscitation) on regaining consciousness in the patients with persistent vegetative state (PVS). METHODS: A total of 50 patients of PVS were randomized into an observation group and a control group, 25 cases in each. The patients in the control group were treated by the routine western medicine, and those in the observation group treated by Xiao's "xingnaofusu" needling and routine western medicine. Baihui (GV20), Dingshen (Extra) to Shangen (Extra) (penetrating technique), Fengchi (GB20) to GB20 (penetrating technique), Neiguan (PC6) to Waiguan (TE5) (penetrating technique), Hegu (LI4) to Laogong (HT8) (penetrating technique) and Taichong (LR3) to Yongquan (KI1) (penetrating technique) were selected. The treatment was given once a day, 10 days as one treatment course, 3 courses in total. The coma recovery scale-revised (CRS-R) score, the modified Ashworth scale (MAS) score and the Glasgow coma scale (GCS) were separately compared before and after the treatment. Additionally, CT scanning was adopted to measure the width of the third ventricle before and after treatment so as to evaluate the clinical therapeutic effect. RESULTS: After the treatment, the CRS-R and GCS scores in the two groups increased remarkably, and MAS score reduced obviously as compared with that before the treatment(P<0.05); and the CRS-R and GCS scores were higher, and MAS score lower in the observation group than those in the control group(P<0.05). Compared with the control group, the width of the third ventricle reduced obviously in the observation group after the treatment(P<0.05). At the end of the treatment courses, the effective rate was 79.2%(19/24)in the observation group and was 47.8%(11/23) in the control group. The effective rate of the observation group was obviously higher than that of the control group (P<0.05). CONCLUSION: Xiao's "xingnaofusu" needling can remarkably improve the central nerve function, promote the recovery of brain function and the motor function of limbs, reduce the width of the third ventricle and improve the clinical therapeutic effect of regaining consciousness in the patients with PVS.

Trastornos prolongados de conciencia postinjuria cerebral aguda / Prolonged disorders of consciousness after an acute brain injury

Only a fraction of patients in coma secondary to a primary acute brain injury develop a vegetative state (VS). At least 20% of patients show late transitions to a minimally conscious states (MCS). They are particularly common in young adults with traumatic brain injury. The main problems faced by clinicians are the diagnostic accuracy of VS and MCS as well as the usefulness of sophisticated paraclinical investigations. Specific therapies are of limited effectiveness. This population is vulnerable to misdiagnosis and limited access to medical care and rehabilitation, thus generating ethical problems.

Court decisions and legal considerations about the withdrawal of the life-prolonging medical care

The Supreme Court decision made on May 21, 2009 about the withdrawal of futile life-prolonging medical care from a persistently vegetative patient provided a legal basis for patients to consent to death with dignity, and also spurred a lively debate in Korea. The legal grounding of this decision was based on the principles of human dignity, worth, and the right to pursue happiness articulated in the Article 10 of the Constitution. The Death with Dignity Act was legislated to regulate decisions about life-prolonging medical care on February 3, 2016, after extensive debate and a focus on consensus that led to two revisions. However, the issue has not been completely resolved. First, the definition of the process of dying is unclear, because the points that determine whether a patient is dying are different from a simple assessment of whether an artificial ventilator should be attached or detached. Second, the purpose of this law is the protection of human dignity, worth, and the right to pursue happiness. However, nutrition, fluids, and oxygen must continue to be supplied, even after cessation of life-prolonging medical care. Is providing a continuous supply of nutrition, fluids, and oxygen a reasonable way to satisfy the goals of Article 10 of the Constitution? Third, if the withdrawal of life-prolonging medical care is possible based on the family's agreement without the patient's input, what is the legal value of advance directives? In conclusion, it may be necessary to partially revise the law regulating decisions on the withdrawal of life-prolonging medical care through further debate.

Clinical and neuroimaging determinants of minimally conscious and persistent vegetative states after acute stroke

BACKGROUND: Patients with persistent vegetative state (PVS) show no evidence of awareness of self or their environment, and those with minimally conscious state (MCS) have severely impaired consciousness with minimal but definite behavioral evidence of self or environmental awareness after stroke. Neuroimaging and clinical characteristics separating these two close consciousness states after stroke were insufficiently studied. METHODS: We conducted a hospital-based cohort study of all patients with stroke (2011 to 2017) who underwent 3T magnetic resonance imaging and consciousness assessment after 3 months of inclusion. Univariate and multivariate regression analyses were used to estimate the relative risk of neuroimaging markers for differentiation of PVS and MCS. RESULTS: Of 3,600 eligible subjects, 323 patients (0.09%) had PVS and 93 (0.02%) had MCS (mean age, 62.25±13.4 years). Higher stroke volume was strongly associated with PVS compared to MCS (odds ratio [OR], 0.99; 95% confidence interval [CI], 0.98 to 1.00; P=0.001). On univariate analysis, cingulate gyrus (OR, 2.7; 95% CI, 1.62 to 4.36; P=0.001) and corpus callosum (OR, 2.1; 95% CI, 1.28 to 3.44; P=0.003) involvement was significantly associated with PVS. However, on multivariate analysis, only cingulate gyrus involvement was independently associated with PVS (OR, 2.2; 95% CI, 1.33 to 3.72; P=0.002). CONCLUSION: Our results indicate that PVS and MCS are different consciousness states according to clinical and neuroimaging findings. To predict outcome, cognitive performance of these patients should be well questioned after stroke.

The influence of moxibustion on the bone metabolism of persistent vegetative state patients / 国际中医中药杂志

Abjective To observe the influence of moxibustion on the bone metabolism of persistent vegetative state patients. Methods A total of 60 patients with persistent vegetative state were divided randomly into the treatment group and control group, 30 in each. Both groups were treated with routine therapy, and the patients used moxibustion on the acupoints of zhongwan, xiawan , qihai and guanyuan. The treatment lasted 12 weeks. The changes of T-lymphoctyte subgroups, serum immunoglobulin were tested and compared before and 12th week after treatment. Result After 12th week treatment, the BMD of distal radius (0.563 ± 0.205 g/cm2 vs. 0.451 ± 0.114 g/cm2, t=2.615), the second lumbar vertebra (0.596 ± 0.108 g/cm2 vs. 0.533 ± 0.127 g/cm2, t=2.069) and the femoral neck (0.567 ± 0.214g/cm2 to 0.463 ± 0.163g/cm2, t=2.117) in the treatment group were significantly higher than those in the control group (Ps＜0.05). The PTH (6.41 ± 0.56 pmol/L vs. 6.72 ± 0.42 pmol/L, t=0.018), CT (217.48 ± 57.35 ng/L vs. 228.46 ± 52.44ng/L, t=0.012) and BGP (9.16 ± 1.57 g/L vs. 10.37 ± 2.37 g/L, t=0.023) in the treatment group were significantly higher than those in the control group (Ps＜0.05). Conclusions Moxibustion can help to treat the bone metabolism of persistent vegetative state patients and prevent the osteoporosis.

Nutritional Assessment in Vegetative and Minimally Conscious Patients

The aim of this study is to investigate the nutritional status in vegetative state (VS) and minimally conscious state (MCS) patients, and to identify correlation between the duration from onset and indices indicating nutritional status. This study included a total of 37 VS and MCS patients. For nutrition assessment, the body mass index (BMI), biochemical parameters such as hemoglobin, total lymphocyte count, albumin and cholesterol levels were measured. The mean BMI was 21.31 ± 2.81 kg/m2. Only 4 patients (10.81%) were classified as underweight, 24 patients (64.86%) had normal BMI, 6 patients (16.22%) were overweight, and 3 patients (8.11%) were obese. The partial correlation coefficients showed that duration from onset has a positive correlation with BMI, and a negative correlation with cholesterol level. This study suggests that regular and properly prescribed enteral feeding in VS and MCS patients would supply stable and appropriate nutrition. Further study is needed with additional nutrition assessments reflecting muscle mass.

Lived Experience of the Mother's Caring of Adult Children with Persistent Vegetative State

PURPOSE: The purpose of this study was to deepen understanding the nature of the care experience by the mothers with adult children in persistent vegetative state. METHODS: Participants were 7 mothers caring for their adult children in persistent vegetative state. Data were collected individually through in-depth interviews on their lived experiences. Also texts were included as data from literary works, novels, movies, essays, and arts containing on patients with persistent vegetative state and their mothers. Data were analyzed by van Manen's phenomenological methodology. RESULTS: The essential themes of caring experiences of the mothers were as follows. The theme in relation to lived time has shown as back to the past and caring experience related lived body has emerged as locked the body in children. The theme related lived space was getting into the swamp and the theme in lived others was derived as lonely struggle into. CONCLUSION: The nature of mothers' caring experiences for adult children in persistent vegetative state is summarized as ‘Do not off hand of hope in a locked state’. This study suggests long-term supports are necessary for mothers to care persistent vegetative state children.

Objective To observe the variation of the blood pressure in patients with persistent vegetative state (PVS) during whirl-pool-bubble bath. Methods 5 PVS patients accepted whirlpool-bubble both therapy, 38℃for 20 minutes. Their blood pressure was recorded 0, 10 and 20 minutes after immersing for 4 weeks. Results The systolic pressure decreased 20 minutes after immersing compared with that just immersing, but all above 60 mmHg. The systolic and diastolic pressure maintained in a satisfactory range during whirlpool-bubble bath. Conclusion Hypotension has not been found in the patients with PVS during whirlpool-bubble bath.

Effect of Electroencephalograph Bionic Electrical Stimulation on Persistent Vegetative State：Cerebral Blood Flow and Metabolism / 中国康复理论与实践

Objective To study the effect of electroencephalograph (EEG) bionic electrical stimulation at Wangu (GB12), Tianzhu (BL10), Neiguan (PC6) on cerebral blood flow and metabolism in patients with persistent vegetative state (PVS). Methods 60 patients with PVS were divided into observation group (n=30) and control group (n=30) according to the random number table. The control group re-ceived routine treatment, including basic management, hyperbaric oxygen therapy, awaking medicine, sensory stimulation, and so on;while the observation group received EEG bionic electrical stimulation at bilateral Tianzhu, Wangu (cheif electrodes) and Neiguan (auxiliary elec-trodes) in addition. They were treated for 30 days. They were assessed with the PVS score, and observed with transcranial Doppler ultra-sound (TCD) and magnetic resonance spectroscopy (MRS) one day before and one day after treatment. Results The incidence of improve-ment was 86.67%in the observation group, more than 60.00%in the control group (P<0.05). The difference of blood flow velocity before and after treatment (ΔVm) of anterior-middle cerebral artery was more in the observation group than in the control group respectively (P<0.001), as well as those of posterior cerebral-vertebral-basilar artery (P<0.01). The N-acetyl aspartic acid/creatine (NAA/Cr) increased more in the observation group than in the control group respectively (P<0.01), and the choline/creatine (Cho/Cr) decreased more (P<0.01), after treatment. Conclusion EEG bionic electrical stimulation can improve the cerebral circulation and metabolism in patients with PVS, which may associate with the wake promoting.

Common Complications after Hypoxic-ischemic Encephalopathy

Hypoxic-ischemic encephalopathy (HIE) is one of the major disease for neuro-rehabilitation, as well as one of the important impairment. HIE typically shows global deterioration of brain function with relative preservation of brain stem reflexes, and topographic pattern of damage; the CA1 hippocampal cells, cerebellar Purkinje cells, neocortical neurons in layers 3, 5, 6 and basal ganglia. The characteristics of patho-mechanism including persistent vegetative state, seizure, autonomic dysfunction and secondary Parkinsonism are causative factors of several complications. Management of these complications sometimes curative, but more often re-adaptive and palliative. Understanding and proper rehabilitation of complications will be one of the most important therapeutic strategies for patients with HIE.

Aspectos puntuales del estado vegetativo persistente / Specific aspects of the persistent vegetative state

El estado vegetativo persistente es una condición clínica caracterizada por la ausencia completa de conciencia sobre uno mismo y el entorno, unido a ciclos de sueño-vigilia, con preservación total o parcial de las funciones hipotalámicas y autonómicas del tallo encefálico. En el presente artículo, el autor discute aspectos puntuales sobre la entidad clínica, basado en su experiencia y en la revisión de la bibliografía sobre el tema; igualmente se exponen elementos clínicos y epidemiológicos de la afección, se propone una clasificación causal, y se enuncian los criterios de la Multisociety Task Force on Persistent Vegetative State para realizar el diagnóstico, así como los exámenes complementarios, que se dividen en estudios imagenológicos y electrofisiológicos. De los hallazgos anatomopatológicos se resaltan 3 patrones fundamentales: lesiones bilaterales y difusas de la corteza cerebral, daños difusos de las conexiones intra- y subcorticales de la sustancia blanca de los hemisferios cerebrales, y necrosis del tálamo; mientras que del tratamiento se proponen 2 pilares básicos: tratar la enfermedad de base y ofrecer cuidados generales. Entre los fármacos -- clasificados en 2 categorías: depresores y estimulantes del sistema nervioso -- se destaca el zolpidem, que ha mostrado los mejores resultados. Finalmente, se plantea que en Cuba se defiende que estos pacientes pueden ser asistidos en la atención primaria de salud.

The persistent vegetative state is a clinical condition characterized by the complete absence of consciousness of oneself and the environment, linked with sleep-wake cycles, with total or partial preservation of hypothalamic and autonomic functions of the brainstem. In this article the author discusses specific aspects related to the clinical entity, based on his experience and literature survey on the subject. Also, clinical and epidemiological elements of the condition are stated, a causal classification is proposed, and the criteria of the Multisociety Task Force on Persistent Vegetative State for diagnosis are set, as well as complementary tests, which are divided in imaging and electrophysiological studies. Of the pathological findings three fundamental patterns are stressed: diffuse bilateral lesions of the cerebral cortex, diffuse damages of white matter intracortical and subcortical connections of the cerebral hemispheres, and necrosis of the thalamus, whereas two basic treatment mainstays are proposed: to treat underlying condition and provide general care. Among the drugs --classified in 2 categories: depressants and stimulants of the nervous system-- zolpidem is highlighted, which has shown the best results. Finally, it is stated that in Cuba it is argued that these patients can be treated at the primary health care.

El espacio de reflexión y debate que ofrece la Bioética debe ser aprovechado, fundamentalmente, en temas tan escabrosos como comprometedores con la existencialidad del hombre. Con el avance impetuoso de la ciencia y la tecnología, los límites entre la vida y la muerte se han dilatado, el contexto del espacio y el tiempo en que se desarrolla la muerte humana ha cambiado. Y no es que no se muera o que se muera mucho menos que en tiempos remotos, sino que los dilemas que se configuran alrededor de la muerte son otros. El poder resolutivo de las ciencias biomédicas hace que cada día nos encontremos ante eventos nunca antes pensados por el hombre por los que surgen estados ontológicos generan dudas sobre referentes éticos solidificados por el hombre. ¿Qué entender por persona? ¿Qué es la muerte? ¿Cómo asumirla? Todas son preguntas que marcan el hilo conductor de la reflexión para responder ante los conflictos de la existencialidad humana en los límites ahora movedizos de la vida.

The opportunity of reflection and debate that offers Bioethics must be well-planned, essentially in crude issues as compromising with the existence of the man. With the impetuous advance of science and the technology the limits between the life and the death have dilated, the context space time in which the human death is developed has changed, is not that it does not die or that dies much less that in remote times, but the dilemmas that are formed around the death are others. The decisive power of biomedical sciences causes that every day we are before events never thought before by the man, arise ontological states that put in crisis and doubt ethical episteme solidified by the man.

E necessário explorar o espaço de reflexão e debate que oferece a bioética, sobretudo em áreas tão delicadas, relacionadas com a existência humana. Com o rápido avanço da ciência e da tecnologia, têm-se ampliados os limites entre a vida e a morte, mudou o contexto espaço-tempo em que se desenvolve a morte humana. Não é que ninguém morra nem menos pessoas morram hoje do que outros tempos, mas são diferentes os dilemas em torno da morte. O poder de resolução das ciências biomédicas permite que ocorram eventos diários jamais concebidos pelo homem; surgem estados ontológicos que põem em crise e questionam alguns epistemes éticos petrificados pelo homem.
