RÉSUMÉ

Objective:To investigate the relationship between arterial blood partial pressure of carbon dioxide and neurological outcome after cardiopulmonary resuscitation.Methods:The clinical data of 116 patients who underwent cardiopulmonary resuscitation admitted to the Intensive Care Unit and Emergency Department of the Second People's Hospital of Hefei from January 2018 to January 2020 were retrospectively analyzed. According to the average arterial blood partial pressure of carbon dioxide within 24 hours after admission, patients were divided into normal (35 mmHg ≤ PaCO 2 ≤ 55 mmHg, 1 mmHg = 0.133 kPa, n = 44), hypercapnia (PaCO 2 > 55 mmHg, n = 51), and hypocapnia (PaCO 2 < 35 mmHg, n = 21) groups. ICU stay, in-hospital mortality, and neurological outcome at discharge were compared among groups. A logistic regression analysis model was established. The relationship between PaCO 2 and neurological outcome was determined. Results:There were no significant differences in age, sex, cardiac arrest time, acute physiological and chronic health evaluation II score at admission, 1-hour mean arterial pressure, location of cardiac arrest, and initial heart rhythm among the three groups (all P > 0.05). ICU stay in the normal group [(7.23 ± 2.55) days] was significantly higher than that in the hypercapnia [(12.21 ± 4.12) days] and hypocapnia [(11.78 ± 4.72) days] groups ( t = 6.48, 4.59, both P < 0.01). In-hospital mortality in the normal group was 38.6% (17/44), which was significantly lower than 60.8% (31/51) in the hypercapnia group and 66.7% (14/21) in the hypocapnia group ( χ2 = 4.63, 4.47, both P < 0.05). The good neurological outcome rate in the normal group was 55.6% (15/44), which was significantly higher than 25.0% (5/51) in the hypercapnia group and 28.6% (2/21) in the hypocapnia group ( χ2 = 8.38, 5.14, both P < 0.05). Multivariate logistic regression analysis showed that cardiac arrest time, 1-hour mean arterial pressure, acute physiological and chronic health evaluation II score, and PaCO 2 are important factors for neurological outcomes of resuscitated patients at discharge (all P < 0.01). Conclusion:Within 24 hours after cardiopulmonary resuscitation, maintaining a normal PaCO 2 level can help improve the neurological outcome of patients at discharge.

Objective:To investigate the value of short-time transcutaneous carbon dioxide pressure (TcPCO 2) and transcutaneous oxygen pressure (TcPO 2) monitoring in critically ill preterm infants. Methods:From January to December 2018, 62 critically ill neonates receiving respiratory support at Guangzhou Women and Children's Medical Center were retrospectively enrolled. A total of 348 sets of paired data including TcPCO 2/TcPO 2 and arterial carbon dioxide pressure (PaCO 2)/arterial oxygen partial pressure (PaO 2) were analyzed. The patients were divided into different groups based upon birth weight (23 cases>1 000 g-≤1 500 g, 129 sets of paired data; 18 cases≤1 000 g, 130 sets of paired data) and gestational age (16 cases born at ≤28 gestational weeks, 127 sets of paired data; 29 cases born at 28-34 gestational weeks, 159 sets of paired data) and the differences between groups were compared. The correlation and consistency of TcPCO 2/TcPO 2 and PaCO 2/PaO 2 were evaluated using Pearson's correlation and Blan-Altman scatter plots. Receiver operating characteristic (ROC) curve was drawn to analyze the diagnostic efficacy of TcPCO 2 in neonates with hypercapnia. Results:There was a positive correlation between TcPCO 2 and PaCO 2 in all patients ( r=0.913, 95% CI:0.894-0.929, P<0.05). In patients whose birth weight was>1 000 g-≤1 500 g or≤1 000 g, TcPCO 2 and PaCO 2 were positively correlated and the consistency were good ( r=0.909, 95% CI:0.874-0.935; r=0.934, 95% CI:0.908-0.953; both P<0.05), and the same finding was also observed in patients born at≤28 gestational weeks or 28-34 weeks of gestation ( r=0.938, 95% CI:0.913-0.956; r=0.871, 95% CI: 0.827-0.904; both P<0.05). The sensitivity, specificity and area under curve of TcPCO 2 in the diagnosis of hypercapnia were 90.91%, 85.85%, and 0.942, respectively. There was a poor correlation between TcPO 2 and PaO 2 in all patients and those with birth weight >1 000 g-≤1 500 g or gestational age 28-34 weeks (all r<0.75, all P<0.05). There was no correlation between TcPO 2 and PaO 2 in the birth weight ≤1 000 g and gestational age ≤28 weeks groups (both P>0.05). Conclusions:Short-time TcPCO 2 monitoring can accurately assess PaCO 2 in critically ill neonates requiring respiratory support and is of high diagnostic value for hypercapnia. However, TcPO 2 has limitation in evaluating PaO 2 and other indicators may need to be involved.

RÉSUMÉ

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.

RÉSUMÉ

BACKGROUND: Polydeoxyribonucleotide (PDRN) is known to have anti-inflammatory and angiogenic effects and to accelerate wound healing. The aim of this study was to investigate whether PDRN could improve peripheral tissue oxygenation and angiogenesis in diabetic foot ulcers. METHODS: This was a prospective randomized controlled clinical trial. Twenty patients with a non-healing diabetic foot ulcer were randomly distributed into a control group (n=10) and a PDRN group (n=10). Initial surgical debridement and secondary surgical procedures such as a split-thickness skin graft, primary closure, or local flap were performed. Between the initial surgical debridement and secondary surgical procedures, 0.9% normal saline (3 mL) or PDRN was injected for 2 weeks by the intramuscular (1 ampule, 3 mL, 5.625 mg, 5 days per week) and perilesional routes (1 ampule, 3 mL, 5.625 mg, 2 days per week). Transcutaneous oxygen tension (TcPO2) was evaluated using the Periflux System 5000 with TcPO2/CO2 unit 5040 before the injections and on days 1, 3, 7, 14, and 28 after the start of the injections. A pathologic review (hematoxylin and eosin stain) of the debrided specimens was conducted by a pathologist, and vessel density (average number of vessels per visual field) was calculated. RESULTS: Compared with the control group, the PDRN-treated group showed improvements in peripheral tissue oxygenation on day 7 (P < 0.01), day 14 (P < 0.001), and day 28 (P < 0.001). The pathologic review of the specimens from the PDRN group showed increased angiogenesis and improved inflammation compared with the control group. No statistically significant difference was found between the control group and the PDRN group in terms of vessel density (P=0.094). Complete healing was achieved in every patient. CONCLUSIONS: In this study, PDRN improved peripheral tissue oxygenation. Moreover, PDRN is thought to be effective in improving inflammation and angiogenesis in diabetic foot ulcers.

Objective To examine the correlation between end-tidal carbon dioxide (PetCO2) and arterial CO2 (PaCO2) among patients admitted in neurosurgical intensive care unit (NICU) and the factors affecting the PaCO2-PetCO2 [P (a-et) CO2].Methods Thirty-two intubated or cut-trachea patients who presented in the NICU were enrolled.Arterial blood gas test was done at seven every morning,and values of PetCO2 were compared with simultaneously recorded PaCO2.The normal gap of P (a-et) CO2 was defined as-5 mmHg to 5 mmHg.Concordance between PaCO2 and PetCO2 was analyzed using the Bland-Altman plot.Parameters between the normal and high P(a-et) CO2 groups were compared to identify the factors affecting the P(a-et) CO2,including Glasgow Coma Scale(GCS),blood pressure (BP),heart rate (HR),respiration rate (RR),body temperature (BT),and pulse oxygen saturation (SpO2).Results Allvalues of PaCO2 and PetCO2 were in accordance with normal distribution (r =0.668,P < 0.01) and concordance between PaCO2 and PetCO2 was 69.8%.Patients who had high P(aet) CO2 showed lower initial GCS,lower instant GCS,BT,as well as pH and higher actual bicarbonate (AB) and PetCO2 than the patients with normal P (a-et) CO2.Correlation between PaCO2 and PetCO2 rapidly declined when positive end expiratory pressure(PEEP) was greater than 5 mmH2O(r =0.229,P < 0.01).Conclusions PetCO2 correlates well with PaCO2 and appears to be a useful monitor of respiratory function of the patients consecutively.Initial GCS,BT,AB and PEEP have an impact on P(a-et) CO2,so those factors should be considered when attempting to monitor the hyperventilation with PetCO2.

RÉSUMÉ

Objetivo: Evaluar prospectivamente y mediante comparación, durante la prueba de marcha de 6 minutos, el comportamiento de la saturación arterial de oxígeno (SPO2) y otras variables vitales, en dos grupos, uno de mineros del carbón (expuestos) y otro de trabajadores universitarios (controles). Materiales y métodos:Estudio prospectivo de cohortes. Se realizó la prueba (PM6M) en 72 trabajadores mineros y 46 trabajadores universitarios. Se midió minuto a minuto SPO2, frecuencia cardiaca y distancia recorrida. Resultados: Se encontró una significativa desaturación de oxígeno, ante un ejercicio moderado, en los trabajadores mineros, equivalente a una manifestación precoz de alteración funcional del intercambio alveolo-capilar. Conclusiones: La exposición respiratoria sostenida a polvo de carbón y sílice podría ocasionar alteración funcional del intercambio gaseoso alveolo capilar. La pulsioximetría en la prueba de marcha de 6 minutos se perfila como una herramienta útil y costo-efectiva en salud ocupacional para el seguimiento y control de la salud de los mineros del carbón.


Objective: To evaluate prospectively and through comparison the behavior of the arterial oxygen saturation (SPO2) and other vital variables in two groups, one of coal miners (exposed) and another formed by university workers (controls) during the test run of 6 minutes. Materials and methods: Prospective cohort study. The test (6MWT) was performed in 72 miners and 46 university workers. SpO2, heart rate and walked distance were estimated every minute. Results: A significant oxygen desaturation was found in the mineworkers when practicing a moderate exercise, which is equivalent to an early manifestation of functional impairment of the alveolar-capillary exchange. Conclusions: The sustained respiratory exposure to coal dust and silica may cause functional impairment of alveolar capillary gas exchange. The pulse oximetry in the 6 minutes walking test is emerging as a useful and cost-effective occupational health tool to monitor and health surveillance of coal miners.

RÉSUMÉ

Objective: To evaluate the behavior of oxygen saturation curves throughout the six-minute walk test (6MWT) in patients with COPD. Methods: We included 85 patients, all of whom underwent spirometry and were classified as having moderate COPD (modCOPD, n = 30) or severe COPD (sevCOPD, n = 55). All of the patients performed a 6MWT, in a 27-m corridor with continuous SpO2 and HR monitoring by telemetry. We studied the SpO2 curves in order to determine the time to a 4% decrease in SpO2, the time to the minimum SpO2 (Tmin), and the post-6MWT time to return to the initial SpO2, the last designated recovery time (RT). For each of those curves, we calculated the slope. Results: The mean age in the modCOPD and sevCOPD groups was 66 ± 10 years and 62 ± 11 years, respectively. At baseline, SpO2 was > 94% in all of the patients; none received supplemental oxygen during the 6MWT; and none of the tests were interrupted. The six-minute walk distance did not differ significantly between the groups. The SpO2 values were lowest in the sevCOPD group. There was no difference between the groups regarding RT. In 71% and 63% of the sevCOPD and modCOPD group patients, respectively, a ≥ 4% decrease in SpO2 occurred within the first minute. We found that FEV1% correlated significantly with the ΔSpO2 (r = −0.398; p < 0.001), Tmin (r = −0.449; p < 0.001), and minimum SpO2 (r = 0.356; p < 0.005). Conclusions: In the sevCOPD group, in comparison with the modCOPD group, SpO2 was lower and the Tmin was greater, suggesting a worse prognosis in the former. .


Objetivo: Avaliar o comportamento da curva de saturação de oxigênio durante o teste de caminhada de seis minutos (TC6) em pacientes com DPOC. Métodos: Incluímos 85 pacientes e todos realizaram espirometria, sendo classificados como portadores de DPOC moderada (DPOCm, n = 30) ou grave (DPOCg, n = 55). Todos os pacientes realizaram TC6 em um corredor de 27 m com monitoramento contínuo da SpO2 e FC por telemetria. A partir das curvas de SpO2, foram analisados os tempos para atingir a queda de 4% da SpO2, para atingir a SpO2 mínima (Tmin) e para a recuperação da SpO2 após o TC6 (TR). Foram calculadas as inclinações dessas curvas. Resultados: A média de idade nos grupos DPOCm e DPOCg foi de 62 ± 11 anos e 66 ± 10 anos, respectivamente. Todos os pacientes iniciaram o teste com SpO2 > 94%, nenhum recebeu suplementação de oxigênio durante o TC6, e não houve interrupções. A distância percorrida no TC6 não apresentou diferença significativa entre os grupos. Os menores valores da SpO2 ocorreram no grupo DPOCg. Não houve diferença no TR entre os grupos, e 71% e 63% dos pacientes nos grupos DPOCg e DPOCm, respectivamente, apresentaram queda de SpO2 ≥ 4% até o primeiro minuto. O VEF1% apresentou correlações significativas com ΔSpO2 (r = −0,398; p < 0,001), Tmin (r = −0,449; p < 0,001) e SpO2 mínima (r = 0,356; p < 0,005). Conclusões: As curvas dos pacientes do grupo DPOCg em relação às do grupo DPOCm apresentaram valores menores de SpO2 e maior Tmin, sugerindo um pior prognóstico nos primeiros. .
