ABSTRACT

La atrofia muscular espinal (AME) 5q es una de las enfermedades neuromusculares de mayor incidencia en la infancia. Sin embargo, la prevalencia de AME tipo 1, su forma más severa de presentación, es menor debido a muertes prematuras evitables antes de los dos años por insuficiencia ventilatoria subtratada. La irrupción de nuevos tratamientos modificadores de la enfermedad pueden cambiar dramáticamente este pronóstico y es una oportunidad para actualizar el manejo respiratorio, a través de cuidados estandarizados básicos, preferentemente no invasivos, abordando la debilidad de los músculos respiratorios, la insuficiencia tusígena y ventilatoria, con un enfoque preventivo. La siguiente revisión literaria entrega estrategias para evitar la intubación y la traqueostomía usando soporte ventilatorio no invasivo (SVN), reclutamiento de volumen pulmonar (RVP) y facilitación de la tos. Se analizan en detalle los protocolos de extubación en niños con AME tipo 1.


Spinal muscular atrophy (SMA) 5q is one of the neuromuscular diseases with the highest incidence in childhood. Nevertheless, the prevalence of its most severe form SMA1 is lower due to premature preventable deaths before two years of age related to ventilatory insufficiency undertreated. The emergence of new disease-modifying treatments can dramatically change this prognosis and is an opportunity to update respiratory management, through basic standardized care, mostly non-invasive, addressing respiratory muscles pump weakness, cough and ventilatory insufficiency with a preventive approach. This literature review provides consensus recommendations for strategies to avoid intubation and tracheostomy using noninvasive ventilatory support (NVS), lung volume recruitment (LVR), and cough facilitation. Extubation protocols in children with SMA type 1 are analyzed in detail.

ABSTRACT

Abstract Objective: To evaluate the success rate of high-flow nasal cannula (HFNC) therapy using an adapted obsolete mechanical ventilator (MV), Optiflow™ and Vapotherm™ in newborns (NBs). Method: This was a retrospective observational study conducted in the neonatal intensive care unit (NICU). The sample comprised NBs who underwent HFNC therapy due to ventilatory dysfunction, for weaning from non-invasive ventilation (NIV), or post-extubation. The three groups, stratified according to gestational age (GA) and birth weight, and corrected GA and weight at the beginning of HFNC use, were as follows: Optiflow ™, Vapotherm ™, and obsolete Mechanical Ventilator (MV) adapted for high flow therapy. Subsequently, the NBs were divided into a success group (SG) and a failure group (FG). HFNC success was defined as a therapy duration exceeding 72 h. Results: A total of 209 NBs were evaluated, with 31.1 % using HFNC due to ventilatory dysfunction, 2.4 % after extubation, and 66.5 % after NIV weaning. HFNC success rate was observed in 90.9 % of the NBs, with no difference between equipment types (Vapotherm ™, Optiflow ™, and adapted VM). Conclusion: Different types of HFNC equipment are equally effective when used in neonatology for respiratory dysfunction, as a method of weaning from NIV and post-extubation. Adapted obsolete MV can be an alternative for HFCN therapy in resource-constrained settings.

ABSTRACT

Abstract Objective: To correlate the nasal anatomical characteristics of newborns with the dimensions of short binasal prongs. Method: Observational, cross-sectional study carried out in two hospitals in southern Brazil. The authors evaluated 1620 newborns with neonatal data and nasal dimensions. To measure the dimensions of the nasal region, the authors considered the width of the medial columella, the right nostril diameter, and the left nostril diameter. These data were correlated with the dimensions of two models of short binasal prongs. Results: Of the total newborns evaluated, 807 were female (49.8%), and 813 were male (50.2%). The majority were white (96.2%). The mean gestational age was 37.4 ± 2.9 weeks, ranging from 22 to 42 weeks. The birth weight was 2946.8 ± 699.3 g, ranging from 490.0 to 4740.0 g. Most of the nasal measures were significantly larger than both prong model measurements. Conclusion: The sizes of short binasal prongs available on the Brazilian market do not match the nasal anatomical characteristics of newborns.

ABSTRACT

Introducción. Las cardiopatías congénitas (CC) en Chile corresponden a la segunda causa de muerte en menores de 1 año, requiriendo cirugías paliativas y/o correctivas el 65% de estas. En el post operatorio frecuentemente se utiliza ventilación mecánica invasiva (VM) y succión endotraqueal (SET) para remover secreciones. Sin embargo, la kinesiología respiratoria (KTR) ha mostrado mejoras significativas en la distensibilidad toracopulmonar (Cest) y resistencia de vía aérea (Rva) en otros grupos de usuarios pediátricos y adultos en VM. Objetivo. Comparar los cambios en la Cest y Rva en usuarios pediátricos en VM post cirugía de cardiopatía congénita (CCC) sometidos a KTR versus SET exclusiva. Métodos. Revisión sistemática de estudios publicados en bases de datos PUBMED, PeDro, Scielo y Google Scholar que comparan el uso de KTR ó SET sobre los cambios en mecánica ventilatoria en usuarios pediátricos en VM post cirugía de cardiopatía congénita, limitados a inglés, español y portugués, excluyendo a sujetos con traqueostomía o con oxigenación por membrana extracorpórea. Se utilizó guía PRISMA para la selección de artículos. Se revisaron 397 artículos y se seleccionó 1 artículo extra de los artículos sugeridos. Se eliminó 1 artículo por duplicidad. Por títulos y resúmenes se seleccionaron 2 artículos, los cuales al leer el texto completo fueron retirados debido a que la población no correspondía a cardiópatas. Resultados. El final de artículos seleccionados fue de 0 artículos, debido a lo cual se removió el operador Booleano "NOT", y se removió la población de cardiopatías. De este modo quedaron 2 artículos seleccionados para la revisión cualitativa final donde se compara KTR versus SET, y KTR en kinesiólogos especialistas y no especialistas, mostrando ambos aumento en la Cest y disminución de la Rva a favor de la KTR, hasta los 30 minutos post intervención. Conclusiones. No se encontraron artículos que demuestren cambios en Cest y Rva con el uso de KTR + SET versus SET exclusiva, en usuarios pediátricos ventilados posterior a CCC. Con la remoción de filtros seleccionamos 2 artículos que demuestran aumento de Cest y disminución de Rva en sujetos pediátricos en VM, uno comparando con SET, y por grupos de especialistas y no especialistas en respiratorio. Se sugieren estudios primarios para evaluar los efectos de esta intervención en esta población.


Introduction. Congenital heart diseases (CHD) are the second general cause for children death under 1 year. In Chile, approximately 65% CHD need surgery, could was palliative or corrective. In the postoperative period, invasive mechanical ventilation (MV) is frequently used as a life support method, but it is associated with complications. Tracheal suction (SET) is regularly used to remove secretions; however, respiratory chest physiotherapy (KTR) has shown significant improvements in thoraco-pulmonary compliance and airway resistance in other groups of pediatrics and adult's users in MV. Objetive. to compare changes in thoraco-pulmonary compliance and airway resistance in pediatric subjects under mechanical ventilation after congenital heart disease surgery comparing chest physiotherapy and exclusive tracheal suction. Methods. systematic review of studies published in PUBMED, PeDro, Scielo and Google Scholar databases who compares KTR or SET use on changes in ventilatory mechanics in pediatric users under MV after congenital heart disease surgery, limited to English, Spanish and Portuguese languages, excluding user with tracheostomy or extracorporeal membrane of oxygenation. It was use the PRISMA guide to articles selection. A search was carried out, with a total of 397 articles reviewed (English: PubMed = 3, PeDro = 8, Scholar = 383; Spanish: Scholar = 3, Scielo = 0; and Portuguese: Scielo = 0). One extra article was selected from the suggested articles, and 1 article was eliminated due to duplication. By titles and abstracts, 2 articles were selected, but the population did not correspond to heart disease. Results. the final selected articles were 0 articles. By this reason, it were removed: Boolean operator "NOT", and congenital heart disease population. Thus, 2 articles were selected for the final qualitative review where it was compares KTR versus SET, and KTR by specialist and non-specialist. Both articles shown improvement in compliance and resistance until 30 minutes post intervention. The CC population was in a 40 to 60% range in both studies. Conclusions. it was no found articles that demonstrate changes in compliance and resistance in the airway with the use of KTR + SET versus exclusive SET in pediatric users after CCC connected to MV. After filter remotion, we found 2 studies shown improves in increase compliance and reduce resistance in pediatric user in MV, ones comparing with SET, and the other one comparing between specialists in respiratory pediatric physiotherapy and not specialists. It suggests to made primary clinical studies about this intervention in CC population.

ABSTRACT

OBJECTIVE To systematically evaluate the efficacy and safety of midazolam and dexmedetomidine/propofol for the sedation of critically ill patients undergoing mechanical ventilation, and to provide evidence-based reference for clinical treatment. METHODS Retrieved from PubMed, Embase, Web of Science, Cochrane Library, Clinical trials. gov, China Journal Full Text Database, Chinese Science and Technology Journal Database, Wanfang database and China Biomedical Literature Database, the data on the efficacy and safety of midazolam and dexmetomidine/propofol for the sedation of critically ill patients undergoing mechanical ventilation were collected from the establishment of the database to March 31, 2023. After extracting data from clinical studies that met the inclusion criteria, the meta-analysis was conducted by using the RevMan 5.3 statistical software. RESULTS A total of 31 literature were included, with a total of 2 765 patients. Results of meta-analysis showed that the mechanical ventilation time [MD=14.13, 95%CI (13.75, 14.52), P<0.000 01] and the length of hospitalization in the intensive care unit [MD=0.92, 95%CI (0.54, 1.30), P<0.000 01] of patients in the midazolam group was longer than dexmedetomidine/ propofol group. The incidence of bradycardia in midazolam group was lower dexmedetomidine/propofol group [OR=0.60, 95%CI (0.41, 0.90), P=0.01], but there was no statistically significant difference in the incidence of hypotension between the two groups [OR=0.69, 95%CI (0.47, 1.01), P=0.06]. The incidence of delirium [OR=3.88, 95%CI (2.74, 5.49), P<0.000 01], ventilator- associated pneumonia [OR=2.32, 95%CI (1.19, 4.51), P=0.01], and respiratory depression [OR=5.70, 95%CI (3.09, 10.52), P<0.000 01] in midazolam group were higher than dexmedetomidine/propofol group. CONCLUSIONS Compared with dexmedetomidine/propofol, midazolam increases patients’ mechanical ventilation time and the length of hospitalization in the intensive care unit in terms of efficacy, and increases the risk of delirium and pulmonary complications in terms of safety, but has a smaller cardiovascular impact.

ABSTRACT

With the optimization of surgical technologies and postoperative management regimens, the number of lung transplantation has been significantly increased, which has become an important treatment for patients with end-stage lung disease. However, due to the impact of comprehensive factors, such as bronchial ischemia and immunosuppression, the incidence of airway stenosis after lung transplantation is relatively high, which severely affects postoperative survival and quality of life of lung transplant recipients. In recent years, with the improvement of perioperative management, organ preservation and surgical technologies, the incidence of airway stenosis after lung transplantation has been declined, but it remains at a high level. Early diagnosis and timely intervention play a significant role in enhancing clinical prognosis of patients with airway stenosis. In this article, the general conditions, diagnosis, treatment and prevention of airway stenosis after lung transplantation were reviewed, aiming to provide reference for comprehensive management of airway stenosis after lung transplantation and improving clinical prognosis of lung transplant recipients.

ABSTRACT

Objective To systematic evaluate the effectiveness and safety of driving pressure-guided fixed positive end-expiratory pressure(PEEP)titration in intraoperative mechanical ventilation.Methods PubMed,Web of Science,the Cochrane Library,Embase,CNKI,Wanfang and VIP databases were searched for collect randomized controlled trials(RCTs)of PEEP titration guided by driving pressure in intraoperative mechanical ventilation from inception to November 8,2023.After two researchers independently screened the literature,extracted data,and evaluated the risk of bias of the included studies,the meta-analysis was conducted by Rev-Man 5.4 software.Results Nineteen studies with a total of 2 906 patients were included.There were 1 440 patients in the study group with the lung protective ventilation strategy guided by PEEP titration,and 1 466 patients in the control group with the traditional lung protective ventilation strategy.Compared with the con-trol group,the incidence of postoperative pulmonary complications(PPCs)in the study group was lower in the non-thoracic surgery(RR=0.53,95%CI:0.43-0.65,P<0.001),but there was no statistical difference in the incidence of PPCS in the thoracic surgery(RR=0.89,95%CI:0.78-1.02,P=0.09).Compared with the control group,the intraoperative lung compliance was increased(MD= 6.90 L/cmH2O,95%CI:5.80-7.99,P<0.001),and the length of hospital stay was shortened in the study group(MD=-0.27 d,95%CI:-0.43 to-0.12,P<0.001),while there was no significant difference in intraoperative mean arterial pres-sure(MAP)between the two groups(MD=0.36 mmHg,95%CI:-1.30 to 2.01,P=0.67).Conclusion Com-pared with the traditional lung protective ventilation,driving pressure-guided PEEP titration ventilation can im-prove intraoperative lung compliance,reduce the incidence of PPCs in non-thoracic surgery,shorten the length of hospital stay,and does not increase the risk of hemodynamic disturbances in patients undergoing surgery.

ABSTRACT

This article takes pectoral qi as the starting point to discuss the traditional Chinese medicine(TCM)pathogenesis as well as the diagnostic and therapeutic approach to difficult withdrawal of mechanical ventilation in mechanically ventilated patients.According to the five-viscera correlation theory,it is believed that the onset of difficult withdrawal of mechanical ventilation is closely related to pectoral qi.The core pathogenesis of difficult withdrawal of mechanical ventilation is due to the insufficiency of pectoral qi and the deficiency of the lung,spleen and kidney,and the obstruction of pectoral qi and disharmony of qi and blood contribute to the key pathogenesis.Chinese medicine treatment can be carried out by the usage of Sijunzi Tang(Four Mild-Drug Decoction),Bufei Tang(Decoction for Replenishing Lung),Shenling Baizhu San(Powder of Radix Ginseng,Poria and Rhizoma Atractylodis Macrocephalae)to supplement and benefit pectoral qi,and by the utilization of Buzhong Yiqi Tang(Decoction for Tonifying Middle Energizer and Replenishing Qi),Shengxian Tang(Decoction for Lifting the Sinking of Qi in Chest),Juyuan Jian(Decoction for Replenishing Qi and Lifting the Sunken Qi)to elevate yang and lift the sinking of Qi.Moreover,herbs for regulating qi and blood should be added,and the management of the diet and daily living based on the identification of the deficiency and excess of the five viscera is stressed,so as to enhance the success rate of withdrawal of mechanical ventilation.The exploration will provide ideas for the treatment of difficult withdrawal of mechanical ventilation with the integrated Chinese and western medicine.

ABSTRACT

Objective To investigate the effects of dynamic lung compliance(Cdyn)-guided indi-vidual positive end-expiratory pressure(PEEP)titration on pulmonary function in elderly patients undergoing laparoscopic colorectal cancer surgery.Methods Sixty-eight elderly patients were selected for laparoscopic radical resection of colorectal cancer,37 males and 31 females,aged 65-79 years,BMI<30 kg/m2,ASA physical status Ⅱ or Ⅲ.The patients were divided into two groups using the random number table method:individualized PEEP group(group P)and control group(group C),34 patients in each group.In group P,the patients received recruitment maneuvers and PEEP titration test at immediately after intubation,immediately after establishing pneumoperitoneum-Trendelenburg position and immediately after pneumoperitoneum.The patients in group C received PEEP 5 cmH2 O during procedure.The three best titra-tion PEEP and the actual tidal volume(VT)in group P were also recorded.PaO2,PaCO2,PETCO2 10 mi-nutes after the tracheal intubation(T1),10 minutes(T2)and 1 hour(T3)after establishing pneumoperito-neum-Trendelenburg position,at the end of the surgery but before extubation(T4)were recorded,and the oxygenation index(OI),physiological dead space to tidal volume(Vd/VT),alveolar arterial oxygen differ-ence(A-aDO2),driving pressure,and Cdyn were calculated.Concentrations of interleukin-8(IL-8),tumor necrosis factor-α(TNF-α),Clara cell secretoyr protein(CC16)and lung alveolar surface active sub-stances-D(SP-D)in the serum samples were determined by ELISA before anesthesia induction(T0)and 10 minutes after extubation(T5).Postoperative pulmonary complications(PPCs)were also recordrd.Results The individualized PEEP of Cdyn?guided PEEP titration was 4 cmH2O. Compared with group C, the PaO2 and OI in group C were significantly increased at T4, the Cdyn was significantly increased at T1,T3, and T4, the driving pressure was significantly decreased at T1 -T4, the serum concentration of CC16 was significantly decreased at T5 ( P < 0. 05). There were no significant differences in PaCO2, PET CO2,A?aDO2, and Vd/ VT between the two groups. There was no severe PPCs in the two groups. Conclusion Pressure?controlled ventilation modes combined with Cdyn?guide PEEP titration can increase the Cdyn, reduce thedriving pressure, and improve OI at the end of the operation, reduce the concentrations of CC16 at postop?eration, improve pulmonary function in elderly patients undergoing laparoscopic colorectal cancer surgery.

ABSTRACT

Objective To investigate the ventilation effect and application safety of pressure-con-trolled ventilation-volume guaranteed(PCV-VG)mode in neonatal thoracoscopic esophageal atresia surgery.Methods Thirty-six newborns who underwent thoracoscopic esophageal atresia surgery under general anes-thesia,22 males and 14 females,aged 1-4 days,weighing 1.4-4.5 kg,ASA physical status Ⅲ or Ⅳ,were divided into two groups using a random number table method:the PCV-VG mode group(group P)and the volume-controlled ventilation(VCV)mode group(group V),18 newborns in each group.After anes-thesia,PCV-VG and VCV ventilation modes were employed for mechanical ventilation in groups P and V,respectively.The MAP,HR,and SpO2 were recorded prior to tracheal intubation,10 minutes before one-lung ventilation(OLV),30 minutes after OLV,and 10 minutes after completion of OLV.Additionally,the Pmean,Ppeak,Pplat,Cdyn,PETCO2,PaCO2,PaO2,and pH were monitored 10 minutes before OLV,30 minutes after OLV,and 10 minutes after completion of OLV.The time of tracheal tube removal after surgery and the duration of ICU retention were also observed.Results Compared with group V,the SpO2,Cdyn,PaO2,and pH levels showed a significant increase,while significant decrease were noted in Pmean,Ppeak,and Pplat in group P 30 minutes after OLV(P<0.05).Compared with group V,the PETCO2 and PaCO2 in group P decreased significantly 30 minutes after OLV and 10 minutes after completion of OLV.Be-sides,compared with group V,the time of tracheal tube removal after surgery and the duration of ICU reten-tion were also significantly shortened in group P(P<0.05).Conclusion The utilization of PCV-VG ven-tilation mode in neonatal thoracoscopic esophageal atresia surgery,as compared to VCV ventilation mode,can effectively reduce airway pressure,enhance lung compliance,optimize intraoperative lung gas exchange,and facilitate postoperative recovery of the neonates.

ABSTRACT

Appropriate positive end-expiratory pressure(PEEP)level is an important component of protective lung ventilation strategy.PEEP can maintain the openness of alveoli and reduce lung collapse in-jury.Although individualized PEEP application has been increasingly recognized by clinical physicians,the optimal PEEP titration method is still controversial.Electrical impedance tomography(EIT)is a non-inva-sive and radiation-free imaging technique that can be used to dynamically assess lung function at the bedside.EIT presents changes in impedance during ventilation as dynamic images,which can reflect altera-tions in ventilation and gas distribution before and after PEEP adjustments.Therefore,EIT can be utilized to tailor individualized PEEP.This article provides a brief overview of the basic principles and monitoring pa-rameters of EIT.It elucidates the PEEP titration method under the guidance of EIT in clinical applications(PEEPEIT),aiming at enhancing the understanding of the advantages and limitations of EIT and providing reference for the setting of individualized PEEP.

ABSTRACT

Objective:To compare the dynamic changes of transcutaneous partial pressure of carbon dioxide (PtCO 2) and treatment effect of non-invasive intermittent nebulization and non-invasive simultaneous nebulization in patients with acute exacerbation of chronic obstructive pulmonary disease (COPD). Methods:This was a randomized parallel controlled trial study. A total of 70 patients with acute exacerbation of COPD in Changzhou First People′s Hospital from October 2021 to September 2022 were selected by convenience sampling method, and divided into control group and experimental group by randomized digits table method with 35 cases in each group. The control group was given non-invasive intermittent oxygen-driven nebulization, and the experimental group was given non-invasive simultaneous oxygen-driven nebulization. The PtCO 2 values at 0, 5, 10, 15 min (the end point of atomization) of the 2 groups were observed, the daily arterial blood gas analysis indexes (mainly including PaCO 2, PaO 2 and pH) were recorded, and the clinical pulmonary infection score and the self-assessment score of COPD patients were recorded before treatment, on the 4th and 7th day of treatment. Results:Finally, 33 patients were included in both the control group and the experimental group. There were 25 males and 8 females in the control group, aged (75.33 ± 8.24) years old. There were 25 males and 8 females in the experimental group, aged (72.39 ± 8.56) years old. The PtCO 2 values at 0, 5, 10, 15 min in the control group were (63.83 ± 12.47), (64.40 ± 12.57), (65.42 ± 13.77), (66.62 ± 14.59) mmHg (1 mmHg=0.133 kPa). There were statistically significant differences in PtCO 2 at all time points ( F=8.05, P<0.01). Further pairwise comparison by Sidak method showed that there were statistically significant differences in PtCO 2 at 15 min compared with 0, 5, 10 min (all P<0.05). The PtCO 2 values at 0, 5, 10, 15 min in the experimental group were (67.62 ± 11.89), (67.15 ± 12.12), (67.82 ± 12.22), (68.15 ± 12.09) mmHg. There was no statistically significant difference in PtCO 2 at all time points ( F=2.00, P>0.05). The PaCO 2 and pH value of the two groups were improved with the treatment time, the control group had a statistically significant difference on the 4th day of treatment compared with before treatment ( P<0.05), while the experimental group on the second day of treatment compared with before treatment ( P<0.05). Conclusions:Both kinds of nebulization have achieved good therapeutic effects, but non-invasive simultaneous nebulization can better maintain the stability of PtCO 2 in the process of nebulization with higher safety, and can improve the arterial blood gas index PaCO 2 and pH value of patients earlier, which is a more suitable nebulization method for the combination of non-invasive ventilation and nebulization, especially for patients with hypercapnia.

Both groups were given routine nursing care, the control group carried out early rehabilitation exercise, the experimental group implemented sling exercise therapy. The diaphragm function, respiratory function after the different time of intervention, and outcome events were compared between two groups.Results:Finally, the experimental group included 34 cases, 22 males and 12 females, aged (55.50 ± 12.03) years old. The control group included 36 cases, 25 males and 11 females, aged (54.78 ± 12.81) years old. There was no significant difference in the diaphragm function, respiratory function before intervention(all P>0.05). After 7 d of intervention, the diaphragmatic excursion, diaphragm thickening fraction were (1.59 ± 0.21) cm, (45.90 ± 5.20) % in the experimental group, which were higher than those in the control group (1.49 ± 0.21) cm, (42.78 ± 5.51) %, the differences were statistically significant ( t=2.13, 2.44, both P<0.05). After 5, 7 d of intervention, the rapid shallow breathing index was (81.47 ± 6.97), (77.29 ± 8.91) times. min -1.L -1 in the experimental group, which were lower than those in the control group (88.36 ± 9.04), (84.67 ± 9.64) times.min -1.L -1; after 3, 5, 7 d on intervention, the oxygenation index was (230.79 ± 44.79), (241.59 ± 23.79), (258.56 ± 23.09) mmHg(1 mmHg=0.133 kPa) in the experimental group, which were higher than those in the control group (197.25 ± 21.21), (212.72 ± 21.81), (242.75 ± 24.37) mmHg, the differences were statistically significant ( t values were 2.78-5.30, all P<0.05). The mechanical ventilator time and the length of stay in ICU were (225.29 ± 47.31) h, (12.47 ± 3.71) d in the experimental group, which were lower than those in the control group (260.53 ± 56.32) h, (14.64 ± 4.53) d, the differences were statistically significant ( t=2.83, 2.18, both P<0.05). The incidence rate of VIDD was 5.9%(2/34) in the experimental group, which was lower than that in the control group 22.2%(8/36), and the weaning success rate was 91.2%(31/34) in the experimental group, which was higher than that in the control group 72.2% (26/36), the differences were statistically significant ( χ2=4.18, 4.15, both P<0.05). Conclusions:Sling exercise therapy can effectively promote diaphragm function and respiratory function, shorten mechanical ventilator time and the length of stay in ICU of patients with mechanical ventilation, and reduce the occurrence of VIDD.

ABSTRACT

Objective To explore the effect of protective ventilation strategies based on individualized positive end expiratory pressure(PEEP)regulated by driving pressure(Pd)in infants under OLV.Methods Sixty infants undergoing elective thoracoscopic surgery were randomly divided into the control group and driving pressure group,with 30 cases in each group.The two groups were compared in terms of MAP,HR,tidal volume(Vt),PEEP,Pd,airway peak pressure(Ppeak),and static lung compliance(Cs),and arterial blood gas during OLV before the artificial pneumothorax(T0),10 min(T1),30 min(T2),and 60 min(T3)after the artificial pneumothorax,and right at the end of the artificial pneumothorax(T4).Results There were no significant differences in MAP,HR,and Vt between the two groups at all the time points(P>0.05).Both groups showed the increase in Pd and Ppeak and decresase in Cs at T1,T2,and T3(all P<0.05).PaO2 and OI in both group were decreased and PaCO2 was increased at T2(all P<0.05).Compared with the control group,the driving pressure group presented lower Pd and Ppeak,higher PEEP and Cs at T1,T2,and T3(P<0.05),and higher PaO2 and OI(P<0.05)and no significant differences in PaCO2 and FiO2 at T2(P<0.05).The rate of rescue ventilation during OLV was lower in the driving pressure group(2 cases)than in the control group(9 cases)(6.9%versus 32.4%,P<0.05).There was no significant difference in the inci-dence of postoperative complications between the two groups(P<0.05).Conclusion The individualized positive end expiratory pressure(PEEP)regulated by Pd can optimize the PEEP settings upon infant individuals under OLV and improve the compliance and oxygenation of ventilated lung.

ABSTRACT

Objective:To analyze clinical characteristics of patients within 48 hours in pediatric intensive care unit(PICU),and investigate causes and prognosis of extubation failure in reintubation children.Methods:A single-center retrospective study was conducted.Patients who were reintubated within 48 hours after extubation in PICU at Children's Hospital of Fudan University from January 1,2019 to December 31,2022 were retrospectively enrolled.Patients with unplanned extubation for various reasons which include re-intubation due to surgery and replacement of tracheal intubation were excluded.We analyzed the clinical characteristics,causes of extubation failure and prognosis.Main outcome measures included principal diagnosis,pediatric critical illness score(PCIS),the reason of intubation,the glasgow coma scale(GCS),the direct cause of reintubation,aeration time,hospitalization period,outcomes at PICU discharge and whether to extubate successfully.Results:During the study period,a total of 2 652 patients were extubated in PICU,and a total of 87 children were enrolled.Finally,63(72.4%)patients survived at PICU,nine(10.3%)patients died in hospital,and 15(17.2%)patients were discharged automatically.In the survival group,38(60.3%)patients were decannulated and 25(39.7%)patients underwent tracheotomy.The top three principal diagnosis in 87 cases were central nervous system disease[34(39.1%)cases],lower airway disease[18(20.7%)cases] and sepsis[nine(10.3%)cases].Of the 87 children,28(32.2%)patients were reintubated due to central respiratory failure,21(24.1%)patients were reintubated due to lower airway disease,20(23.0%)patients were reintubated due to upper airway obstruction,14(16.1%)patients were reintubated due to cough weakness and/or swallowing disturbance,and four(4.6%)patients were reintubated for other reasons.In children with mechanical ventilation duration ≥7 days before first extubation,central nervous system diseases were the most common primary diseases,and it accounts for 55.6%.Central respiratory failure was the main direct cause of reintubation,accounting for 40.0%,and more patients(40.0%) had GCS scores<8 before the first intubation.Compared with the successful decannulation group,the extubation failure group had the higher proportion of children with GCS<8(32.7% vs.10.5%, P<0.05),the longer median duration of mechanical ventilation before the first extubation[239(123,349)h vs.68.5(19,206)h, P<0.05]and the longer median length of ICU stay[38(23,54)d vs.24(12,43)d, P<0.05].After comparing the three groups including survival group,in-hospital death group and automatic discharge group,the PCIS score of the survival group was the highest,and the in-hospital death group was the lowest( P<0.05). Conclusion:The rate of reintubation at 48 h after extubation in PICU is 3.3%.The immediate causes of reintubation mainly included central respiratory failure,lower airway disease,upper airway obstruction,cough weakness and/or dysphagia.The mortality rate of reintubation in critically ill children is high and the prognosis is poor.
