ABSTRACT
OBJECTIVES@#To study the change in regional oxygen saturation (rSO@*METHODS@#The preterm infants with patent ductus arteriosus (PDA) who had gestational age <32 weeks and/or birth weight <1 500 g were prospectively enrolled, who were admitted to the Department of Neonatology, Shenzhen Longgang Central Hospital from October 2017 to October 2020.According to the diagnostic criteria for hsPDA, the preterm infants with patent ductus arteriosus (PDA) were divided into two groups: hsPDA and non-hsPDA. According to closure of the ductus arteriosus after oral administration of ibuprofen, the preterm infants in the hsPDA group were subdivided into two groups: hsPDA closure and hsPDA non-closure. Hemodynamic parameters were measured at diagnosis of PDA and after treatment, and the level of intestinal tissue rSO@*RESULTS@#A total of 241 preterm infants with PDA were enrolled, with 55 infants (22.8%) in the hsPDA group and 186 infants (77.2%) in the non-hsPDA group. There were 36 infants (65%) in the hsPDA closure group and 19 infants (35%) in the hsPDA non-closure group. Compared with the non-hsPDA group, the hsPDA group had a significantly higher left atrial diameter/aortic root diameter ratio and significantly lower left ventricular ejection fraction and fractional shortening (@*CONCLUSIONS@#hsPDA has an impact on intestinal tissue oxygenation in preterm infants, and continuous monitoring of intestinal tissue rSO

Objective@#To observe the changes in cerebral regional oxygen saturation (CrSO2) during neonatal blood exchange transfusion(BET) and its effect on the level of bilirubin in neonates with severe hyperbilirubinemia.@*Methods@#From January 2017 to March 2018, 52 newborns with severe hyperbilirubinemia were hospitalized in the Department of Neonatology, Children′s Hospital of Fudan University.Every newborn was treated with BET.Near infrared spectroscopy was used to monitor CrSO2 in the process of BET.The monitoring lasted from 2 hours before the beginning of BET to 2 hours after the completion of BET.The CrSO2 were recorded every 2 minutes and total surem bilirubin (TSB) and transcutaneous bilirubin(TCB) was measured.During this period, it is accompanied by the monitoring of neonatal body temperature, heart rate, respiration and bolld oxygen saturation(SpO2). The differences in CrSO2 changes at different time points during BET were compared.At the same time, the correlations between CrSO2 and blood oxygen saturation, TSB and TCB levels were analyzed.The results of repeated measurement analysis of variance compared between the two groups were corrected by Bonfferoni.@*Results@#Among the 52 children, there were 33 males (63.46%) and 19 females (36.54%). The gestational age, average birth weight and average head circumference of newborns were (38.6±2.1) weeks, (3 338±444) g and (33.6±3.2) cm, respectively.The Apgar score of newborn was (8.1±1.6) scores at 1 minute after birth.The level of TSB detected for the first time after admission was (457.9±97.8) μmol/L.The CrSO2 after BET (74.6%-76.0%) was significantly higher than that before BET (69.4%-69.0%), and the difference was statistically significant (P<0.05). Correlation analysis showed that during BET, CrSO2 showed a gradual upward trend, SpO2 also showed a synchronous increase, while the level of bilirubin showed a downward trend, and the downward trend of TSB level was more obvious than that of TCB.@*Conclusions@#CrSO2 can reflect the improvement of cerebral oxygenation during neonatal blood exchange transfusion and avoid cerebral hypoxia in the course of treatment.
ABSTRACT
@#Objective To assess the predictive abilities of postoperative regional oxygen saturation (rSO2) measured by near-infrared spectroscopy (NIRS) and lactate level for early postoperative outcome in children undergoing congenital heart disease surgery. Methods A total of 73 children (43 males, 30 females, mean age of 91±18 days) undergoing cardiovascular surgery were enrolled from December 2016 to September 2017. The 73 children were divided into an early poor outcome group and a without poor outcome group. Binary logistic regression method was used to determine the independent factors of predicting early poor outcome. Receiver operating characteristic curve was used to identify the optimal cutoff values. Results The early poor outcome rate was 47%. By regression analyses, nadir splanchnic rSO2 values, peak lactate level were 2 independent factors of predicting poor outcome. For nadir splanchnic rSO2 alone, the area under the ROC curve for poor outcome were 0.897. For peak lactate alone, the area under the ROC curve for poor outcome was 0.867. After combination of nadir splanchnic rSO2 and peak lactate, the area under the ROC curve for poor outcome increased to 0.944 (P<0.05). Conclusion Combining the parameter of nadir splanchnic rSO2 and peak lactate during the first postoperatively 24 hours yielded to a more accurate predictive ability for early outcome in children undergoing congenital cardiac surgery.
ABSTRACT
Resumen: Introducción: Desde hace algún tiempo es tema de controversia el mantenimiento de la perfusión cerebral durante la cirugía de hombro realizada en posición de silla de playa. El objetivo de este reporte es presentar el primer caso en México de una artroplastía total de hombro realizada con bloqueo interescalénico y monitoreo de la saturación cerebral de oxígeno. Este monitoreo se describió en 1977, pero sólo hasta la última década ha alcanzado relevancia desde el punto de vista clínico. Caso clínico: Paciente de 84 años programado para artroplastía total de hombro en posición de silla de playa bajo anestesia regional tipo bloqueo interescalénico guiado por ultrasonido, en la cual se monitoreó la saturación regional de oxígeno (CrSO2). Discusión: El monitoreo de la oximetría cerebral es una herramienta adecuada que nos permite tener una valoración continua durante todo el transanestésico, con lo que podemos tomar decisiones de forma más expedita. Con base en esto consideramos que este tipo de monitoreo debe ser básico en pacientes colocados en posición de silla de playa, así como el uso preponderante de anestesia regional; en los casos donde ésta no se pueda utilizar, este monitor es primordial.
Abstract: Introduction: The maintenance of cerebral perfusion during shoulder surgery performed in the beach chair position is controversial. The aim of this report is to present the first case in Mexico of a total shoulder arthroplasty performed with interscalene block and monitoring of the cerebral oxygen saturation. This monitoring was described in 1977, but only until the last decade has it reached relevance from the clinical point of view. Clinical case: We present an 84-year-old patient scheduled for total shoulder arthroplasty in beach chair position under regional anesthesia (ultrasound-guided interscalene block) in which the regional oxygen saturation (CrSO2) was monitored. Discussion: Monitoring of cerebral oximetry is a suitable tool that allows us to have a continuous assessment throughout the transanesthetic, so we can make decisions more expeditiously. On this basis, we believe that this type of monitoring should be fundamental in patients placed in a beach chair position, as well as predominantly use regional anesthesia. In cases where it cannot be used, this monitor is absolutely essential.

Objective To investigate the correlation between regional cerebral oxygen saturation (rSO2) value and the prognosis of comatose patients in the intensive care unit (ICU).Methods From January 2013 to September 2014, a total of 64 comatose patients admitted in the department of ICU were enrolled.The patients were divided into two groups : consciousness group (n =25) and coma group (n =39).The level of the Glasgow coma scale (GCS), APACHE Ⅱ score and Full Outline of UnResponsiveness score (FOUR) of patients were monitored.The rSO2 was measured by Somanetics INVOS 5100 monitor.Results The differences in levels of FOUR and GCS at admission and GCS at discharge between the two groups were statistically significant (P ＜ 0.05).In the consciousness group, the levels of GCS、 FOUR and rSO2 were higher compared with the coma group (P ＜ 0.05).ROC curve analysis revealed that the areas under the curve of GCS, FOUR and rSO2 for predicting prognosis were 0.823 (0.718-0.928), 0.820 (0.728-0.912) and 0.924 (0.863-0.985) respectively.Conclusions The rSO2 was useful for estimating the prognosis of comatose patients in general ICU.
