A novel predictor of persistent ocular hypotony after pars plana vitrectomy for rhegmatogenous retinal detachment: The initial intraocular pressure difference between the eye with RRD and the fellow eye

ABSTRACT Purpose: To evaluate the predictive value of initial intraocular pressure difference of the detached and fellow eyes of patients with complex rhegmatogenous retinal detachment on postoperative persistent ocular hypotony. Methods: This retrospective observational study included 538 eyes of 538 unilateral complex rhegmatogenous retinal detachment patients with a proliferative vitreoretinopathy grade of C-1 or higher, treated with silicone oil endotamponade following pars plana vitrectomy. The patients were divided into Group A (patients having silicone oil removal without ocular hypotony; n=504) and Group B (patients with persistent ocular hypotony following silicone oil removal [n=8, 23.5%] and with retained silicone oil [n=26, 76.5%] due to the risk of persistent ocular hypotony; total n=34). Ocular hypotony was defined as an intraocular pressure of <6 mmHg on two or more occasions. Patients' demographics, including age, sex, and follow-up time, and ocular characteristics, including ocular surgical and trauma history, initial and final best-corrected visual acuity, intraocular pressure and initial intraocular pressure difference of the detached and fellow eyes, and anatomical success rates and postoperative complications, were retrospectively collected from the electronic patient files. Results: The initial intraocular pressure was significantly lower in the detached eyes of Group B than in Group A (8.3 ± 3.5 vs. 12.9 ± 3.3, p<0.001). Also, the initial intraocular pressure difference was significantly higher in Group B than in Group A (8.9 ± 3.2 vs. 2.2 ± 2.7mmHg, p<0.001). The receiver operating characteristic curve analysis showed that the cutoff value of the initial intraocular pressure difference was 7.5mmHg for the risk of persistent ocular hypotony. The most influential factors on postoperative persistent ocular hypotony in the binary logistic regression analysis were the initial intraocular pressure difference and the need for a retinectomy. Conclusion: In eyes with complex rhegmatogenous retinal detachment treated with pars plana vitrectomy and silicone oil tamponade, the initial intraocular pressure difference could be of value in predicting postoperative persistent ocular hypotony and could guide surgeons on the decision of silicone oil removal.

Comparison of safety and effectiveness of micropulse transscleral cyclophotocoagulation and "slow cook" diode laser transscleral cyclophotocoagulation in patients with refractory open-angle glaucoma

ABSTRACT Purpose: This study aimed to compare the safety and effectiveness of intraocular pressure reduction between micropulse transscleral cyclophotocoagulation and "slow cook" transscleral cyclophotocoagulation in patients with refractory primary open-angle glaucoma. Methods: We included patients with primary open angle glaucoma with at least 12 months of follow-up. We collected and analyzed data on the preoperative characteristics and postoperative outcomes. The primary outcomes were a reduction of ≥20% of the baseline value (criterion A) and/or intraocular pressure between 6 and 21 mmHg (criterion B). Results: We included 128 eyes with primary open-angle glaucoma. The preoperative mean intraocular pressure was 25.53 ± 6.40 and 35.02 ± 12.57 mmHg in the micropulse- and "slow cook" transscleral cyclophotocoagulation groups, respectively (p<0.001). The mean intraocular pressure was reduced significantly to 14.33 ± 3.40 and 15.37 ± 5.85 mmHg in the micropulse- and "slow cook" transscleral cyclophotocoagulation groups at the last follow-up, respectively (p=0.110). The mean intraocular pressure reduction at 12 months was 11.20 ± 11.46 and 19.65 ± 13.22 mmHg in the micropulse- and "slow cook" transscleral cyclophotocoagulation groups, respectively (p<0.001). The median preoperative logMAR visual acuity was 0.52 ± 0.69 and 1.75 ± 1.04 in the micropulse- and "slow cook" transscleral cyclophotocoagulation groups, respectively (p<0.001). The mean visual acuity variation was −0.10 ± 0.35 and −0.074 ± 0.16 in the micropulse- and "slow cook" transscleral cyclophotocoagulation, respectively (p=0.510). Preoperatively, the mean eye drops were 3.44 ± 1.38 and 2.89 ± 0.68 drugs in the micropulse- and "slow cook" transscleral cyclophotocoagulation groups, respectively (p=0.017), but those were 2.06 ± 1.42 and 1.02 ± 1.46 at the end of the study in the "slow cook" and micropulse transscleral cyclophotocoagulation groups, respectively (p<0.001). The success of criterion A was not significant between both groups. Compared with 11 eyes (17.74%) in the "slow cook" transscleral cyclophotocoagulation group, 19 eyes (28.78%) in the micropulse transscleral cyclophotocoagulation group showed complete success (p=0.171). For criterion B, 28 (42.42%) and 2 eyes (3.22%) showed complete success after micropulse- and "slow cook" transscleral cyclophotocoagulation, respectively (p<0.001). Conclusion: Both techniques reduced intraocular pressure effectively.

Intraocular pressure modulation with thermal stimuli

ABSTRACT Purpose: This study aimed to determine whether early-stage intraocular pressure can be modulated using a thermal face mask. Methods: In this prospective clinical study, healthy participants were randomized on a 1:1:1 allocation ratio to three mask groups: hypothermic (G1), normothermic (G2), and hyperthermic (G3). After randomization, 108 eyes from 108 participants were submitted to clinical evaluations, including measurement of initial intraocular pressure (T1). The thermal mask was then applied for 10 minutes, followed by a second evaluation of intraocular pressure (T2) and assessment of any side effects. Results: The hypothermic group (G1) showed a significant reduction in mean intraocular pressure between T1 (16.97 ± 2.59 mmHg) and T2 (14.97 ± 2.44 mmHg) (p<0.001). G2 showed no significant pressure difference between T1 (16.50 ± 2.55 mmHg) and T2 (17.00 ± 2.29 mmHg) (p=0.054). G3 showed a significant increase in pressure from T1 (16.53 ± 2.69 mmHg) to T2 (18.58 ± 2.95 mmHg) (p<0.001). At T1, there was no difference between the three study groups (p=0.823), but at T2, the mean values of G3 were significantly higher than those of G1 and G2 (p<0.00). Conclusion: Temperature was shown to significantly modify intraocular pressure. Thermal masks allow the application of temperature in a controlled, reproducible manner. Further studies are needed to assess the duration of these effects and whether they are reproducible in patients with pathologies that affect intraocular pressure.

Night-time blood pressure dipping, but not 24-h blood pressure level, is linked to increased 24-h ocular volume slope

ABSTRACT Purpose: This study investigated the relationship between blood pressure and intraocular pressure in treatmentnaive, non-glaucoma patients with different blood pressure statuses, focusing on the 24-h ocular volume and nocturnal blood pressure decline. Methods: Treatment-naive, non-glaucoma patients undergoing hypertension evaluation were enrolled as study participants. Simultaneous 24-h ambulatory blood pressure measurement and 24-h ocular volume recording with a contact lens sensor. We also compared ocular volume curve parameters between normotensive and hypertensive patients, as well as between those with and without nocturnal blood pressure decline. Results: A total of 21 patients, including 7 normotensive and 14 treatment-naive hypertensive individuals, were included in the study. of them, 11 were dippers and 10 were non-dippers. No significant difference in the 24-h ocular volume slope was observed between the hypertensive and normotensive patients (p=0.284). However, dippers had a significantly higher 24-h ocular volume slope (p=0.004) and nocturnal contact lens sensor output (p=0.041) than non-dippers. Conclusion: Nocturnal blood pressure decline, rather than the blood pressure level, is associated with the increased 24-h ocular volume slope and nocturnal ocular volume. Further studies are required to determine whether the acceleration of glaucoma progression in dippers is primarily due to low blood pressure, high intraocular pressure, or a combination of both.

Association between chronic kidney disease stages and changes in ambulatory blood pressure monitoring parameters / Associação entre estágios da doença renal crônica e alterações dos parâmetros da monitorização ambulatorial da pressão arterial

Abstract Introduction: Blood pressure (BP) assessment affects the management of arterial hypertension (AH) in chronic kidney disease (CKD). CKD patients have specific patterns of BP behavior during ambulatory blood pressure monitoring (ABPM). Objectives: The aim of the current study was to evaluate the associations between progressive stages of CKD and changes in ABPM. Methodology: This is a cross-sectional study with 851 patients treated in outpatient clinics of a university hospital who underwent ABPM examination from January 2004 to February 2012 in order to assess the presence and control of AH. The outcomes considered were the ABPM parameters. The variable of interest was CKD staging. Confounding factors included age, sex, body mass index, smoking, cause of CKD, and use of antihypertensive drugs. Results: Systolic BP (SBP) was associated with CKD stages 3b and 5, irrespective of confounding variables. Pulse pressure was only associated with stage 5. The SBP coefficient of variation was progressively associated with stages 3a, 4 and 5, while the diastolic blood pressure (DBP) coefficient of variation showed no association. SBP reduction was associated with stages 2, 4 and 5, and the decline in DBP with stages 4 and 5. Other ABPM parameters showed no association with CKD stages after adjustments. Conclusion: Advanced stages of CKD were associated with lower nocturnal dipping and greater variability in blood pressure.

Resumo Introdução: A avaliação da pressão arterial (PA) tem impacto no manejo da hipertensão arterial (HA) na doença renal crônica (DRC). O portador de DRC apresenta padrão específico de comportamento da PA ao longo da monitorização ambulatorial da pressão arterial (MAPA). Objetivos: O objetivo do corrente estudo é avaliar as associações entre os estágios progressivos da DRC e alterações da MAPA. Metodologia: Trata-se de um estudo transversal com 851 pacientes atendidos nos ambulatórios de um hospital universitário que foram submetidos ao exame de MAPA no período de janeiro de 2004 a fevereiro de 2012 para avaliar a presença e o controle da HA. Os desfechos considerados foram os parâmetros de MAPA. A variável de interesse foi o estadiamento da DRC. Foram considerados como fatores de confusão idade, sexo, índice de massa corporal, tabagismo, causa da DRC e uso de anti-hipertensivos. Resultados: A PA sistólica (PAS) se associou aos estágios 3b e 5 da DRC, independentemente das variáveis de confusão. Pressão de pulso se associou apenas ao estágio 5. O coeficiente de variação da PAS se associou progressivamente aos estágios 3a, 4 e 5, enquanto o coeficiente de variação da pressão arterial diastólica (PAD) não demonstrou associação. O descenso da PAS obteve associação com estágios 2, 4 e 5, e o descenso da PAD, com os 4 e 5. Demais parâmetros da MAPA não obtiveram associação com os estágios da DRC após os ajustes. Conclusão: Estágios mais avançados da DRC associaram-se a menor descenso noturno e a maior variabilidade da pressão arterial.

Hipertensión arterial nocturna: análisis según su gravedad / Nocturnal Hypertension: Analysis According to its Severity

RESUMEN Introducción: En el diagnóstico y seguimiento de la hipertensión arterial (HTA) la mayoría de las guías de práctica recomiendan el monitoreo ambulatorio de la presión arterial (MAPA). En este sentido, existe cada vez más evidencia que respalda la superioridad de la hipertensión arterial nocturna (HTAN) como predictor de eventos cardiovasculares. Se sabe poco sobre la relación con los eventos cardiovasculares según la gravedad de la HTAN. Además, no está claro a partir de qué valor de presión arterial nocturna comienza a aumentar el riesgo. Objetivos: Conocer si la presencia de HTAN y sus niveles de gravedad se asocian con resultados cardiovasculares adversos durante el seguimiento. Material y métodos: Estudio observacional. Realizamos un análisis de los datos obtenidos en un centro médico de alta complejidad de Buenos Aires, recopilados a partir de estudios de MAPA de 24 horas. Examinamos las características clínicas de los pacientes, los resultados de laboratorio, los estudios de imagen y sus resultados durante el período de seguimiento. Nuestro estudio incluyó personas de 18 años o más a las que se les había diagnosticado hipertensión. Definimos HTAN como aquellos casos con valores de presión arterial ≥ 120/70 mmHg durante el periodo nocturno. Resultados: Fueron incluidos 981 pacientes en el análisis final. De ellos, el 53 % eran hombres; la edad media era de 59,4 años. Presentaban HTAN 63,6 % (n=624). Clasificamos la HTAN en cuatro estratos de gravedad para comparar, según el valor de presión arterial sistólica nocturna: 83-119 mmHg, 120-139 mmHg, 140-159 mmHg y 160-220 mmHg. Se registraron eventos adversos cardiovasculares mayores en 8 (2,2 %), 17 (4,1 %), 8 (5,6 %) y 7 (11,3 %) sujetos, respectivamente, y esta diferencia entre grupos fue estadísticamente significativa (p=0,007). El análisis multivariado de regresión de Cox demostró que la presencia de HTAN fue un predictor independiente de eventos cardiovasculares adversos (HR 3,60; IC 95% 1,12-11,5; p=0,033), incluso al considerar la presencia de hipertensión arterial diurna. Conclusión: En esta cohorte contemporánea, la HTAN y su gravedad se asociaron independientemente con la incidencia de eventos cardiovasculares adversos.

ABSTRACT Background: In the diagnosis and follow-up of arterial hypertension (HTN) most practice guidelines recommend ambulatory blood pressure monitoring (ABPM). In this regard, there is increasing evidence supporting the superiority of nocturnal hy pertension (NHTN) as a predictor of cardiovascular events. Little is known about the relationship with cardiovascular events according to the severity of NHTN. Furthermore, it is unclear from what nighttime pressure value the risk begins to increase. Objectives: The aim of this study was to determine whether the presence of NHTN and its severity levels are associated with adverse cardiovascular outcomes during follow-up. Methods: An observational study was performed analyzing data collected from 24-hour ABPM studies obtained in a high complexity medical center in Buenos Aires. We examined patients' clinical characteristics, laboratory findings, imaging studies and their results during the follow-up period. Our study included ≥18 year-old persons who had been diagnosed with hypertension. We defined NHTN as those cases with blood pressure values ≥120/70 mmHg during the nighttime period. Results: The final analysis included 981 patients. Among these, 53% were men, mean age was 59.4 years and NHTN was present in 63.6% of cases (n=624). Nocturnal HTN was classified into four severity strata for comparison, according to the nighttime systolic blood pressure value: 83-119 mmHg, 120-139 mmHg, 140-159 mmHg and 160-220 mmHg. Major adverse cardiovascular events were recorded in 8 (2.2%), 17 (4.1 %), 8 (5.6%) and 7 (11.3%) subjects, respectively, and this differ ence between groups was statistically significant (p=0.007). Multivariate Cox regression analysis showed that the presence of NHTN was an independent predictor of adverse cardiovascular events (HR 3.60; 95% CI 1.12-11.5; p=0.033), even when considering the presence of daytime hypertension. Conclusion: In this contemporary cohort, NHTN and its severity were independently associated with the incidence of adverse cardiovascular events.

La tomografía por impedancia eléctrica (TIE) es una modalidad de monitorización funcional respiratoria por imagen, no invasiva y libre de radiación, que permite visualizar en tiempo real la ventilación pulmonar regional y global en pacientes adultos y pediátricos conectados a Ventilación Mecánica (VM). OBJETIVO: Se describe la utilidad de la TIE en dos pacientes críticos pediátricos, en quienes no fue factible realizar medición de mecánica pulmonar, como herramienta para el ajuste de parámetros ventilatorios. CASOS CLÍNICOS: Se presentan dos pacientes pediátricos de 27 y 11 meses con condiciones clínicas diferentes, conectados a VM, en quienes se utilizó la TIE como método de monitoreo de la distribución pulmonar y titulación de la presión positiva al final de la espiración (PEEP) óptima, con el objetivo de obtener una ventilación pulmonar más homogénea. Se presentan mediciones funcionales con diferentes niveles de PEEP y valores de distribución en las distintas regiones de interés (ROI), además de un flujograma de situaciones en las que la TIE podría resultar útil para el ajuste ventilatorio. CONCLUSIÓN: La información funcional proporcionada por la TIE, permitió monitorizar de forma dinámica la VM y optimizar los parámetros ventilatorios, facilitando la implementación de estrategias de protección pulmonar en ambos pacientes, imposibilitados de realizar una medición estática de la mecánica respiratoria.

The Electrical Impedance Tomography (EIT) is a non-invasive and radiation-free respiratory functional imaging monitoring modality that allows real-time visualization of regional and global lung ventilation in adult and pediatric patients connected to mechanical ventilation (MV). OBJECTIVE: This paper describes the utility of EIT in two critical pediatric patients for whom measuring pulmonary mechanics was not feasible. EIT is used as a tool for adjusting ventilatory parameters. CLINICAL CASES: Two pediatric patients aged 27 and 11 months, with different clinical conditions, connected to MV are presented. EIT was used to monitor lung distribution and titrate the optimal Positive End-Expiratory Pressure (PEEP), to achieve more homogeneous lung ventilation. Functional measurements are presented with different PEEP levels and distribution values in different regions of interest (ROI), along with a flowchart illustrating situations where EIT could be useful for ventilatory adjustment. CONCLUSION: The functional information provided by EIT, allowed dynamic monitoring of MV, optimizing ventilatory parameters and facilitating the implementation of lung protective strategies in both patients, unable to undergo static respiratory mechanics measurements.

Immediate effects of Chandra Nadi Shuddhi Pranayama on blood pressure, heart rate and rate pressure product among normal individuals: an experimental study

Background: Chandra Nadi Shuddhi Pranayama is a type of alternate nostril breathing which is the control-positive inhalation and exhalation process. Alternate nostril breathing technique shows the best result in health improvement especially in controlling the blood pressure. It activates the parasympathetic nervous system which dilates blood vessels, decreases the heart rate which leads to reduce blood pressure. Many studies have been done to see effects of breathing exercises on cardiovascular system however, no such studies were done to see specific and immediate effect of Chandra Nadi Shuddhi on cardiovascular system. In this article, we will look how Chandra Nadi Shuddhi improves blood pressure, heart rate, and rate pressure product. Methods: Ethical clearance and participant consent was taken. Study design was experimental study. The 80 subjects were taken by convenient sampling. Participants were asked to perform 27 rounds of the Chandra Nadi Shuddhi Pranayama and outcome measures were assessed before and immediately after performing Chandra Nadi Shuddhi. The normality of the data was assessed using parametric paired t test. Results: Immediate effect of Chandra Nadi Shuddhi Pranayama showed that there was statistically significant decrease in blood pressure, heart rate and rate pressure product (p=0.0001, 0.0045, 0.0001 respectively) Conclusions: There is immediate effects of Chandra Nadi Shuddhi Pranayama on individuals with normal blood pressure.These results suggest a possible role for this technique in helping to control hypertension, lower anxiety and depression, improve breathing and immunity.

Neurosarcoidosis as a rapidly progressive dementia associated with normal pressure hydrocephalus / Neurosarcoidosis como demencia rápidamente progresiva asociada a hidrocefalia normotensiva

Abstract Neurosarcoidosis (NS) is a rare subtype of sarcoidosis with a poor prognosis and diverse clinical presentations that often poses a diagnostic and therapeutic challenge. We describe the case of a 53-year-old male with an initial diagnosis of lingual sarcoidosis, who subsequently developed ataxia and rapidly progressive cognitive im pairment. A lumbar puncture revealed hypoglycorrha chia, hyperproteinorrachia, lymphocytic pleocytosis, and elevated IL-6 levels (600 pg/ml). Cerebrospinal fluid flow cytometry showed an elevated CD4 lymphocyte con centration and a CD4+/CD8+ ratio of 3.91, indicative of NS. Brain MRI showed hyperintense periventricular and subcortical lesions on FLAIR/T2 resembling progressive multifocal leukoencephalopathy (PML), although nega tive PCR for JC virus ruled out the differential diagnosis. Following a favorable evolutionary course with cortico steroid pulses, the patient relapsed with normotensive hydrocephalus, treated with immunosuppressants and ventriculoperitoneal shunting with a good response to date. This case underscores the importance of maintain ing a high index of suspicion for NS in individuals with sarcoidosis and neurologic symptoms. In these cases, ce rebrospinal fluid biomarkers such as IL-6 and CD4+/CD8+ ratio are essential to guide the diagnosis. Furthermore, it highlights that hydrocephalus is a rare complication and requires a multidisciplinary approach, including medical and neurosurgical treatment.

Resumen La neurosarcoidosis es un subtipo raro de sarcoidosis con mal pronóstico y diversas presentaciones clínicas que a menudo plantea un reto diagnóstico y terapéutico. Describimos el caso de un varón de 53 años con diagnóstico inicial de sarcoidosis lingual, que posterior mente desarrolló ataxia y deterioro cognitivo de rápida evolución. Una punción lumbar reveló hipoglucorraquia, hiperproteinorraquia, pleocitosis linfocítica y niveles elevados de IL-6 (600 pg/ml). La citometría de flujo del líquido cefalorraquídeo mostró una concentración ele vada de linfocitos CD4 y un cociente CD4+/CD8+ de 3.91, indicativo de neurosarcoidosis. La RM cerebral evidenció lesiones hiperintensas periventriculares y subcorticales en FLAIR/T2 que se asemejaban a una leucoencefalopa tía multifocal progresiva (LMP), aunque la PCR negativa para el virus JC descartó el diagnóstico diferencial. Tras un curso evolutivo favorable con pulsos de corticoides, el paciente recayó con hidrocefalia normotensiva, tratada con inmunosupresores y derivación ventriculoperitoneal con buena respuesta hasta la fecha. Este caso subraya la importancia de mantener un alto índice de sospecha de neurosarcoidosis en individuos con sarcoidosis y síntomas neurológicos. En estos casos, los biomarcadores del líquido cefalorraquídeo tales como la IL-6 y el cociente CD4+/CD8+ son esenciales para orientar el diagnóstico. Además, destaca que la hidro cefalia es una complicación poco frecuente y requiere un abordaje multidisciplinario, que incluya tratamiento médico y neuroquirúrgico.

Abstract Mean arterial pressure is an indirect indicator of the degree of organ perfusion, which could vary in diabetics and non-diabetics. The objective of this research was to determine the differences and risk of alterations in the mean arterial pressure of adults with and without diabetes mellitus-2 of the Peruvian population according to data from the family health demographic survey. An observational, analytical, retrospective and cross-sectional study was carried out. The data came from the demographic and family health survey-2022 (ENDES-2022). Diabetic and non-diabetic adults were included. The variables were mean arterial pressure, diabetes mellitus-2, sex, and the variables age, alcohol consumption, educational level, and body mass index were included for multivariate analysis. Pearson's Chi-square test, student's T test for independent samples, crude Odds Ratio and adjusted by binary logistic regression were performed. The mean arterial pressure in diabetics was 94.81 and 93.52 mmHg in the first and second measurements, and in non-diabetics it was 89.18 and 88.02 mmHg. High mean arterial pressure was more frequent in diabetics than in non-diabetics. In the logistic model, including the variables sex and age, diabetics had a risk twice as high as non-diabetics for alterations in mean arterial pressure in both the first and second measurements. In conclusion, diabetes mellitus-2 increases mean arterial pressure and represents a risk factor for elevated mean arterial pressure in the Peruvian population.

Application of warm water foot bath therapy for stage two hypertension clients in the family context

Hypertension is often regarded as a silent killer because the disease often causes no symptoms in the sufferers. This disease does not only need treatment, but family support is required to prevent and treat family members who are suffering. The objective of the study is to analyze the application of warm water for foot bath therapy to lower blood pressure in people suffering from hypertension. The design used is descriptive with case studies, through family nursing process. Monitoring of warm water foot bath was carried out for 3 days, before and after measuring the blood pressure Results: there was a decrease in blood pressure after 3 days of action. In family 1, the initial blood pressure was 160/90 mmHg, after 3 days of action it decreased to 145/85 mmHg. Family 2 before therapy 150/100 mmHg, decreased to 140/86 mmHg after soaking feet in warm water. The decrease in blood pressure observed in both families was more than 10 mmHg. The application of foot bath therapy using warm water which is carried out for 3 days, is effective in reducing blood pressure in hypertension cases. Suggestions are recommended for families and subjects to be able to apply independently warm water foot bath therapy and carry out routine blood pressure checks at the nearest healthcare facility.

Pulmonary strain and end-expiratory lung volume during apnea test: a comparative analysis using electrical impedance tomography / Stress pulmonar y volumen pulmonar de fin de es piración durante el test de apnea: estudio compara tivo utilizando tomografía por impedancia eléctrica

Abstract The apnea test, employed for brain death assessment, aims to demonstrate the absence of respiratory drive due to hypercapnia. The tracheal oxygen insufflation apnea test mode (I-AT) involves disconnecting the pa tient from invasive mechanical ventilation (iMV) for ap proximately 8 minutes while maintaining oxygenation. This test supports the diagnosis of brain death based on a specified increase in PaCO2. Common complications include hypoxemia and hemodynamic instability, and lung collapse-induced reduction in end-expiratory lung volume (EELV). In our case series utilizing electrical impedance to mography (EIT), we observed that continuous positive airway pressure during the apnea test (CPAP-AT) effec tively mitigated lung collapse. This resulted in improved pulmonary strain compared to the disconnection of iMV. These findings suggest the potential benefits of routine CPAP-AT, particularly for potential lung donors, emphasizing the relevance of our study in providing quantitative insights into EELV loss and its association with pulmonary strain and potential lung injury.

Resumen La prueba de apnea es una técnica diagnóstica am pliamente utilizada para la evaluación de la muerte cerebral, con el objetivo de demostrar la ausencia de impulso respiratorio debido a la hipercapnia. La variante de la prueba de apnea con insuflación de oxígeno traqueal (I-AT) implica desconectar al pacien te de la ventilación mecánica invasiva (iVM) durante aproximadamente 8 minutos, manteniendo la oxigena ción mediante un catéter de insuflación. Esta prueba respalda el diagnóstico de muerte cerebral cuando se determina un aumento de la PaCO2 superior a 20 mmHg en comparación con el valor inicial o un nivel de PaCO2 superior a 60 mmHg al final de la prueba. En nuestra serie de casos, la implementación de la tomografía de impedancia eléctrica (EIT) reveló que la prueba de apnea con presión positiva continua (CPAP-AT) mitiga eficazmente el colapso pulmonar. Este enfo que resulta en una mejora en la tensión pulmonar en comparación con la desconexión de iMV, demostrando su relevancia en el contexto de potenciales donantes de pulmones.

Effects of moderate sedation induced by propofol or midazolam on intracranial pressure / Efeitos da sedação moderada induzida por propofol ou midazolam na pressão intracranial

INTRODUCTION: Propofol and midazolam are the main options for moderate sedation in clinical practice. In addition, these drugs are used to reduce intracranial pressure in cases of intracranial hypertension, and their use in these situations is guided by limited evidence. OBJECTIVE: To compare the effects of propofol and midazolam on intracranial pressure wave morphology in moderate sedation in patients undergoing upper digestive endoscopy. METHODS: Sixty patients were included in this study, being divided into two groups, propofol and midazolam group. Intracranial pressure was monitored during and after upper digestive endoscopy, using non-invasive monitoring equipment developed by the company Brain4care. Arterial pressure was measured before and after the exam. RESULTS: The propofol group had lower intracranial pressure (p=0.037) during moderate sedation compared to intracranial pressure after endoscopy and a significant decrease in systolic (p=0.0001) and diastolic pressure (p=0.001) after sedation. Midazolam, on the other hand, reduced systolic pressure (p=0.001), but didn't change the other parameters after the procedure. There wasn't a significant difference between the propofol and midazolam groups. CONCLUSION: There was no significant difference between the groups studied, however, analyses within the propofol and midazolam groups indicate that propofol, but not midazolam, causes changes in intracranial pressure in moderate sedation.

INTRODUÇÃO: O propofol e o midazolam são as principais opções para sedação moderada na prática clínica. Além disso, esses medicamentos são usados para reduzir a pressão intracraniana em casos de hipertensão intracraniana e seu uso nessas situações é orientado por evidências limitadas. OBJETIVO: Comparar os efeitos do propofol e do midazolam na morfologia da curva de pressão intracraniana na sedação moderada em pacientes submetidos à endoscopia digestiva alta. MÉTODOS: Sessenta pacientes foram incluídos nesse estudo, sendo divididos em dois grupos: propofol e midazolam. A pressão intracraniana foi monitorada durante e após a endoscopia digestiva alta, usando um equipamento de monitoramento não invasivo desenvolvido pela empresa Brain4care. A pressão arterial foi medida antes e depois do exame. RESULTADOS: O grupo do propofol apresentou pressão intracraniana mais baixa (p=0,037) durante a sedação moderada em comparação com a pressão intracraniana após a endoscopia, e uma diminuição significativa na pressão sistólica (p=0,0001) e diastólica (p=0,001) após a sedação. O midazolam, por outro lado, reduziu a pressão sistólica (p=0,001), mas não alterou os outros parâmetros após o procedimento. Não houve diferença significativa entre os grupos propofol e midazolam. CONCLUSÃO: Não houve diferença significativa entre os grupos estudados; entretanto, as análises dentro dos grupos de propofol e midazolam indicam que apenas o propofol causa alterações na pressão intracraniana em sedação moderada.
