INTRODUÇÃO: A Doença Pulmonar Obstrutiva Crônica (DPOC) é um distúrbio crônico e progressivo, que evolui com o declínio da função pulmonar. Embora sua cronicidade, são comuns períodos de agudização acompanhados de Insuficiência Respiratória Aguda hipercápnica, requisitando permanência nas Unidades de Terapia Intensiva (UTI) e Ventilação Mecânica Invasiva (VMI) para reversão da falência respiratória. O desmame na DPOC ocupa até 58% da VM, logo, se faz necessário estratégias específicas para otimização desse processo, com a utilização de modos e ajustes ventilatórios que promovam um desmame precoce e efetivo. OBJETIVO: Verificar os efeitos da Ventilação com Pressão de Suporte quando comparado com modos e estratégias distintas no desmame de pacientes com DPOC. MÉTODOS: Revisão sistemática, construída seguindo critérios do PRISMA, registrada na PROSPERO (CRD42022362228). Considerados elegíveis ensaios clínicos controlados randomizados que avaliaram o modo PSV em comparação com modos e estratégias distintas, em pacientes com diagnóstico de DPOC, em VMI, sem delimitação de ano/idioma. Foram excluídos artigos incompletos, duplicados e indisponíveis aos recursos de recuperação. Desfechos de interesse foram: duração do desmame, tempo de permanência na UTI e mortalidade. A estratégia foi aplicada nas bases: PubMed, Cochrane, SciELO, e Biblioteca Virtual em Saúde. As ferramentas Escala PEDro e RevMan Web foram utilizadas para análise da qualidade dos estudos e risco de viés, respectivamente. RESULTADOS: Incluídos 8 artigos. 6 mostraram significância estatística, apresentando menor tempo de desmame no grupo ASV (24 (2062) h versus 72 (24144) h PSV) (p=0,041); mais dias na UTI quando comparado com o modo PAV (p<0,001). PSV foi mais eficaz nos mesmos desfechos quando comparado com a estratégia Tubo-T. Houve diferenças quanto a taxa de mortalidade com o modo NAVA. CONCLUSÃO: Fica evidente que o modo PSV quando em relação a modos ventilatórios assistidos, tem potencial de fornecer piores desfechos associados ao processo de desmame da ventilação invasiva de pacientes com DPOC.
INTRODUCTION: Chronic Obstructive Pulmonary Disease (COPD) is a chronic and progressive disorder that evolves with the decline in lung function. Despite its chronicity, periods of exacerbation accompanied by hypercapnic Acute Respiratory Failure are common, requiring a stay in Intensive Care Units (ICU) and Invasive Mechanical Ventilation (IMV) to reverse respiratory failure. Weaning in COPD occupies up to 58% of the MV, therefore, specific strategies are needed to optimize this process, using ventilatory modes and adjustments that promote early and effective weaning. OBJECTIVE: To verify the effects of Pressure Support Ventilation when compared with different modes and strategies in weaning patients with COPD. METHODS: Systematic review, constructed following PRISMA criteria, registered at PROSPERO (CRD42022362228). Randomized controlled clinical trials that evaluated the PSV mode in comparison with different modes and strategies, in patients diagnosed with COPD, on IMV, without delimitation of year/language, were considered eligible. Incomplete, duplicate and unavailable articles were excluded. Outcomes of interest were: duration of weaning, length of stay in the ICU and mortality. The strategy was applied in the bases: PubMed, Cochrane, SciELO, and Biblioteca Virtual em Saúde. The PEDro Scale and RevMan Web tools were used to analyze study quality and risk of bias, respectively. RESULTS: Included 8 articles. 6 showed statistical significance, showing shorter weaning time in the ASV group (24 (2062) h versus 72 (24144) h PSV) (p=0.041), and more days in the ICU when compared to the PAV mode (p<0.001). PSV was more effective on the same outcomes when compared with the T-tube strategy. There were differences in the mortality rate with the NAVA mode. CONCLUSION: It is evident that the PSV mode, when compared to assisted ventilation modes, has the potential to provide worse outcomes associated with the process of weaning from invasive ventilation in patients with COPD.

OBJECTIVES@#To systematically evaluate the efficacy and safety of noninvasive high-frequency oscillatory ventilation (NHFOV) versus nasal intermittent positive pressure ventilation (NIPPV) as post-extubation respiratory support in preterm infants.@*METHODS@#China National Knowledge Infrastructure, Wanfang Data, Chinese Journal Full-text Database, China Biology Medicine disc, PubMed, Web of Science, and the Cochrane Library were searched for articles on NHFOV and NIPPV as post-extubation respiratory support in preterm infants published up to August 31, 2022. RevMan 5.4 software and Stata 17.0 software were used for a Meta analysis to compare related indices between the NHFOV and NIPPV groups, including reintubation rate within 72 hours after extubation, partial pressure of carbon dioxide (PCO2) at 6-24 hours after switch to noninvasive assisted ventilation, and the incidence rates of bronchopulmonary dysplasia (BPD), air leak, nasal damage, periventricular leukomalacia (PVL), intraventricular hemorrhage (IVH), and retinopathy of prematurity (ROP).@*RESULTS@#A total of 9 randomized controlled trials were included. The Meta analysis showed that compared with the NIPPV group, the NHFOV group had significantly lower reintubation rate within 72 hours after extubation (RR=0.67, 95%CI: 0.52-0.88, P=0.003) and PCO2 at 6-24 hours after switch to noninvasive assisted ventilation (MD=-4.12, 95%CI: -6.12 to -2.13, P<0.001). There was no significant difference between the two groups in the incidence rates of complications such as BPD, air leak, nasal damage, PVL, IVH, and ROP (P>0.05).@*CONCLUSIONS@#Compared with NIPPV, NHFOV can effectively remove CO2 and reduce the risk of reintubation, without increasing the incidence of complications such as BPD, air leak, nasal damage, PVL, and IVH, and therefore, it can be used as a sequential respiratory support mode for preterm infants after extubation.

Objective:To analyze the effect of lung protective ventilation on lung ventilation function and serum Clara cell protein 16 (CC16) level in patients undergoing gynecological laparoscopic surgery.Methods:The clinical data of 80 gynecological patients who underwent laparoscopic surgery in Yancheng City Jianhu County People′s Hospital from October 2018 to December 2020 were randomly divided into group A and group B by random number table, each group with 40 cases. The patients in group A were treated with intermittent positive-pressure ventilation, and the patients in group B were ventilated with whole course ventilation mode. The pulmonary ventilation function, CC16 level and postoperative pulmonary complications were observed before anesthesia, 10 min of pneumoperitoneum, 30 min of pneumoperitoneum, 5 min of pneumoperitoneum stop and 2 h after operation. The patients were divided into groups according to whether with pulmonary complications, and their pulmonary ventilation function and serum CC16 level were compared. The predictive value of the above indexes for pulmonary complications was analyzed by receiver operating characteristic (ROC) curve.Results:Repeated measurement analysis of variance showed that alveolar arterial oxygen differential pressure (PA-aDO 2) were significant differences in time point factors, time point interaction factors and group factors ( P<0.05); CC16 index were significant differences in time point factor and group factor ( P<0.05). According to the observation from postoperative to discharge, 4 patients (10.0%) in group A had pulmonary complications, 15 cases (37.5%) had pulmonary complications in group B, the levels of PA-aDO 2 and CC16 in patients with complications were significantly higher than those in patients without complications: group A:(332.9 ± 2.0) mmHg (1 mmHg = 0.133 kPa) vs. (290.4 ± 13.2) mmHg, (53.5 ± 1.5) μg/L vs. (39.5 ± 6.5) μg/L; group B: (339.1 ± 8.8) mmHg vs. (305.7 ± 17.9) mmHg, (41.5 ± 4.2) μg/L vs. (39.7 ± 5.8) μg/L, there were statistical differences ( P<0.05). ROC curve analysis showed that the area under the curve(AUC) of PA-aDO 2 and CC16 in predicting pulmonary complications in group A were 0.882 and 0.833, in group B was 0.885 and 0.731. Conclusions:Lung protective ventilation has little effect on lung ventilation function and serum CC16 in patients with gynecological laparoscopic surgery, and the probability of pulmonary complications is lower. The pulmonary ventilation function and CC16 have certain value in predicting postoperative pulmonary complications.

Objective:To investigate the efficacy and safety of nasal continuous positive airway pressure (NCPAP) combined with inhalation of pulmonary surfactant (PS) using vibrating mesh nebulizers in the treatment of neonatal respiratory distress syndrome (RDS).Methods:A prospective study was performed on premature infants with RDS admitted to the First Affiliated Hospital of Bengbu Medical College between December 2020 and June 2021. They were randomly assigned into vibrating mesh atomization technology group and intubation-surfactant-extubation (INSURE) technology group. The two groups were treated with NCPAP combined with PS. PS in the vibrating mesh atomization technology group was inhaled into the lungs by the new vibrating mesh atomization technology, while PS in the INSURE group was injected into the lungs by endotracheal tube. The pH value, arterial partial pressure of carbon dioxide (PaCO 2), oxygenation index (PaO 2/FiO 2), mechanical ventilation via endotracheal tube (MVET) demand rate, duration of respiratory support, secondary use of PS, complications, and hospital mortality were compared between the two groups. The occurrences of adverse events in the two groups were recorded. Results:A total of 42 preterm infants were finally enrolled, including 20 cases in the vibrating mesh atomization technology group and 22 cases in the INSURE technology group. There were no significant differences in blood gas analysis and PaO 2/FiO 2 before PS administration between the two groups. One hour after PS administration, blood gas analysis and PaO 2/FiO 2 were significantly improved in both groups. Compared with the INSURE technology group, the improvement of PaO 2/FiO 2 was more obvious in the vibrating mesh atomization technology group [mmHg (1 mmHg≈0.133 kPa): 198±34 vs. 173±39, P < 0.05], but no significant difference in pH value or PaCO 2 was found between the two groups. The duration of respiratory support in the vibrating mesh atomization technology group was significantly shorter than that in the INSURE technology group (hours: 96±13 vs. 120±18, P < 0.01), but there was no statistical difference in MVET demand rate [5.0% (1/20) vs. 13.6% (3/22), P > 0.05]. The incidence of periventricular-intraventricular hemorrhage (PVH-IVH) in the vibrating mesh atomization technology group was less than that in the INSURE technology group [0% (0/20) vs. 18.2% (4/22)], but no statistical difference was found ( P > 0.05). No significant differences in the secondary use rate of PS and incidence of bronchopulmonary dysplasia (BPD) or other complications were found between the vibrating mesh atomization technology group and the INSURE technology group [5.0% (1/20) vs. 9.1% (2/22), 5.0% (1/20) vs. 4.5% (1/22), both P > 0.05]. There were no deaths or serious adverse events such as pneumothorax, pulmonary hemorrhage, periventricular leukomalacia (PVL), retinopathy of prematurity (ROP), and necrotizing enterocolitis (NEC) in both groups. Conclusion:Compared with the INSURE technique, NCPAP combined with vibrating mesh atomization technology was also effective and safe in the treatment of RDS, which could significantly improve PaO 2/FiO 2 and shorten the duration of respiratory support. Thus, it was worthy of clinical popularization and application.

Objective:To study the efficacy of nasal intermittent positive pressure ventilation (NIPPV) and minimally invasive surfactant therapy (MIST) in very preterm infants with respiratory distress syndrome (RDS).Methods:From January to December 2020, very preterm infants (gestation age ≤30 weeks) with RDS born and treated in our hospital were randomly assigned into NIPPV group and nasal continuous positive airway pressure (NCPAP) group. Both groups were treated with MIST technique. The following items were compared between the two groups:adverse reactions during MIST, partial pressure of carbon dioxide (PaCO 2) at 2 h after MIST, the incidences of intubation within 72 h, two or more doses of pulmonary surfactant (PS), frequent apnea, other complications and the parameters of respiratory support treatment. Results:A total of 62 cases were included, with 32 in the NIPPV group and 30 in the NCPAP group. Compared with the NCPAP group, the NIPPV group had lower incidences of bradycardia (6.3% vs. 30.0%), decreased oxygen saturation (12.5% vs. 40.0%) and apnea (6.3% vs. 30.0%) during MIST ( P<0.05). No significant difference existed in the incidence of regurgitation ( P>0.05). PaCO 2 at 2 h after MIST [40.1(38.2,43.8)mmHg vs. 48.3(44.1,50.0)mmHg], the incidences of intubation within 72 h (6.3% vs. 30.0%), two or more doses of PS (6.3% vs. 30.0%)and frequent apnea (6.3% vs. 30.0%) in NIPPV group were lower than NCPAP group ( P<0.05). No significant differences existed between the two groups on the following items: the durations of invasive ventilation, non-invasive ventilation, oxygen therapy, the incidences of bronchopulmonary dysplasia, intraventricular hemorrhage (≥Ⅲ), periventricular leukomalacia, retinopathy of prematurity (≥Ⅱ), necrotizing enterocolitis (≥Ⅱb), nasal injury, air leak and death ( P>0.05). Conclusions:Combining NIPPV and MIST can reduce the incidence of adverse reactions during PS administration without increasing respiratory support duration and common complications in preterm infants. It is recommended for clinical use.

Background and Aims: Baska mask is a newly introduced membranous cuffed supraglottic device whereas I-gel is made up of thermoplastic elastomer, both suitably designed from the anatomical perspective of the airway. Settings and Design: We conducted randomized controlled comparative trial of the Baska mask versus I-gel in a patient undergoing laparoscopic cholecystectomy. Subjects and Methods: A total of 100 adult patients in the age group of 20–70 years undergoing elective laparoscopic cholecystectomy were randomly divided into two groups as follows: (1) Baska mask group and (2) I-gel group. The primary outcome was to compare oropharyngeal leak pressure (OLP) of Baska mask and I-gel groups. The secondary outcome was the ease of insertion and removal, number of attempts, insertion time, leak fraction, and laryngopharyngeal morbidity. Statistical Analysis Used: Demographic details were compared using the Chi-square and t-tests. Student's t-test for independent variables was used to compare means of data obtained. Results: Mean OLP was significantly higher in Baska mask group than I-gel group at insertion (29.54 ± 1.41 cm H2O vs. 23.16 ± 3.07 cm H2O, P = 0.02) and 30 min after insertion (33.54 ± 1.16 cm H2O vs. 25.97 ± 2.25 cm H2O, P = 0.001). Insertion time was 12.33 ± 2.61 s with Baska mask and 11.31 ± 1.84 s with I-gel (P = 0.02). Insertion was very easy in 58% of patients in Baska mask and 76% of patients in I-gel (P = 0.03). The leak fraction of Baska mask was significantly less than I-gel (3.56 ± 3.6 vs. 7.16 ± 2.45, P = 0.01). Laryngopharyngeal morbidity was comparable in the two groups. Conclusion: Baska mask is more effective in providing greater OLP compared to I-gel without any increase in laryngopharyngeal morbidity.

Objective To investigate the significance of permissive hypercapnia( PHC) in the treat-ment of neonates with respiratory failure using synchronized nasal intermittent positive pressure ventilation. Methods A retrospective study was conducted in 47 neonates with respiratory failure admitted to our NICU during January 2015 to December 2017. The subjects were divided into PHC group ( n =27, PaCO245 ~70 mmHg,1 mmHg=0. 133 kPa) and non-permissive hypercapnia( non-PHC) group( n=20,PaCO235~45 mmHg),respectively. The blood gas indicators(PaO2,PaCO2,PaO2/FiO2) before and after non-invasive ventilation treatment were compared;Ventilator parameters of the two groups ( PIP, PEEP, PiO2 , Ti ) were compared. Duration of oxygen therapy,non-invasive ventilation time,starting time of feeding,length of hospi-tal stay,the incidence of intracranial hemorrhage,air leakage,ventilation induced lung injury,and reintubation rate were compared between the two groups. Results After treatment,the blood gas indexes of PaO2 and OI at 24h in two groups were significantly higher than those before the treatment(P<0. 05). There was no sig-nificant difference on PaO2 and OI between two groups both before and after treatment. PaCO2 was lower in non-PHC group after treatment than that before the treatment(P<0. 05),but it showed no difference in PHC group (P>0. 05). The PIP value of the ventilator parameters in PHC group[(19. 9 ± 2. 7) mmHg] was sig-nificantly lower than that in the non-PHC group[(21. 7 ± 2. 3) mmHg](P<0. 05),and there was no statisti-cally significant difference between the two groups in the other ventilator parameters(P>0. 05). Duration of oxygen therapy,starting time of feeding,the time of using noninvasive ventilation,length of hospital stay in PHC group were shorter obviously than those in non-PHC group [ ( 79. 5 ± 10. 8 ) h vs. ( 92. 7 ± 19. 1 ) h;(34.3±8.8)hvs.(47.1±10.8)h;(67.4±12.3)hvs.(97.6±17.3)h;(11.0±4.6)dvs.(14.0±3.9) d](P<0. 05). The incidences of air leakage,and intracranial hemorrhage showed no significant difference between PHC group and non-PHC group(3/27 cases vs. 4/20 cases;3/27 cases vs. 2/20 cases)(P>0. 05). There was no significant difference between the two groups in the rate of reintubation of invasive ventilation after non-invasive ventilation failure ( 2/27 cases vs. 3/20 cases, P > 0. 05 ) . The incidence of ventilator induced lung injury was significantly lower in PHC group than that in non-PHC group ( 2/27 cases vs. 7/20 cases) ( P<0. 05 ) . Conclusion The effects of treating respiratory failure were similar in PHC group and non-PHC group. However,the PHC treatment could shorten the time of oxygen therapy,non-invasive ventila-tion time and hospitalization time,reduce the incidence of lung injury associated with ventilator. The clinical efficacy of PHC was more significant.

Objective To investigate the clinical effect of synchronized nasal intermittent positive pressure ventilation (SNIPPV) in the treatment of neonatal respiratory failure. Methods The clinical data of 52 neonates with respiratory failure treated in our hospital from January 2016 to January 2018 were retrospec-tively analyzed. According to the different treatment methods,they were divided into observation group and control group,26 cases in each group. The children in the observation group were treated with SNIPPV,while those in the control group were treated with synchronized intermittent positive pressure ventilation (SIPPV). Clinical efficacy,changes of blood gas analysis results before and after treatment,oxygen consumption time and hospital stay,and complications were compared between the two groups. Results The respiratory rate and heart rate of the two groups improved after treatment,but there were no significant differences between the two groups(P>0. 05,respectively). The total effective rate of the observation group was 88. 5%,while that of the control group was 92. 3%,there was no significant difference between the two groups(χ2=0. 221, P>0. 05). The pH,PaO2,PaCO2and oxygen saturation levels of 24 h after treatment in two groups were im-proved (P<0. 05,respectively),but there were no significant differences between the two groups (P>0. 05, respectively). Compared with the control group,the oxygen consumption time and hospitalization time of the observation group were significantly shorter, and the differences were statistically significant ( P <0. 05, respectively). And the observation group had fewer complications of ventilator associated pneumonia. Conclusion The effect of SNIPPV in the treatment of neonatal respiratory failure is significant. It could shorten the time of oxygen consumption and hospitalization and reduce the complications. It is worth populari-zing SNIPPV mode assisted ventilation.

Introducción: en los últimos años, la supervivencia del recién nacido de alto riesgo y enfermo ha aumentado. Estos neonatos requieren cuidados intensivos especiales para resolver complicaciones cada vez más complejas y su vida depende -en muchas ocasiones- de un soporte ventilatorio. Objetivos: caracterizar las diferentes modalidades ventilatorias utilizadas en el Hospital Docente Ginecobstétrico de Guanabacoa. Métodos: estudio observacional, descriptivo, prospectivo y longitudinal en 946 recién nacidos que ingresaron en el servicio de Neonatología, desde 2013 hasta 2015. La muestra estuvo constituida por 67 neonatos que necesitaron asistencia ventilatoria. Resultados: solo 7 por ciento de los neonatos que ingresaron requirieron ventilación; de ellos, 55 por ciento fueron a recién nacidos pretérmino y 54 por ciento fue bajo peso al nacer. La bronconeumonía connatal (54 por ciento) resultó ser la de mayor incidencia como afección que requirió la ventilación, seguidas de la depresión al nacer (24 por ciento) y la sepsis sistémica connatal (13 por ciento). La modalidad ventilatoria más utilizada fue la ventilación con presión positiva intermitente, con la que se reportó la menor supervivencia; mientras que en los que se utilizó la presión positiva continua nasal, no se produjo ninguna muerte neonatal. Conclusiones: el índice de ventilación fue de 1,04 por ciento. La bronconeumonía fue la principal afección que conllevó asistencia ventilatoria y la mayor sobrevida se alcanzó cuando se utilizó presión positiva continua nasal(AU)
Introduction: In recent years, the survival of the high risk and sick newborn has increased. These infants require special intensive care to resolve increasingly. Objectives: Characterize the different ventilatory modalities used in Guanabacoa Gynecobstetric Teaching Hospital. Methods: An observational, descriptive, prospective and longitudinal study was conducted in 946 newborns who entered the neonatal service from 2013 to 2015. The sample consisted of 67 infants who needed ventilatory assistance. Results: Only 7 percent of infants admitted required ventilation; 55 percent were preterm infants and 54 percent were low birth weight. Connatal bronchopneumonia (54 percent) was found to have the highest incidence as a condition requiring ventilation, followed by depression at birth (24 percent) and systemic congenital sepsis (13 percent). The most used ventilatory modality was ventilation with intermittent positive pressure, with which the lowest survival was reported; while nasal continuous positive pressure was used. No neonatal death occurred. Conclusions: Ventilation index was 1.04 percent. Bronchopneumonia was the main condition that led to ventilatory assistance and the highest survival was achieved when nasal continuous positive pressure was used(AU)

Objective · To investigate the effects of low tidal volume mechanical ventilation and low level of positive end expiratory pressure (PEEP) on respiratory function in patients with asthma under general anesthesia. Methods · Forty-five patients with asthma undergoing upper abdominal surgery under general anesthesia were selected and randomly divided into three groups, with 15 cases in each group. Group A received a regular tidal volume of 10 mL/kg, group B a low tidal volume of 6 mL/kg and group C a low tidal volume of 6 mL/kg combined with 5 cmH2O PEEP. Ppeak was recorded at different time points, including the time of induction under anesthesia and the time of 5, 30 and 60 minutes after anesthesia induction. Based on such parameters, Cdyn were also calculated. Moreover, blood gas analysis index (PaO2 and PaCO2) were documented at the time of deoxidation period for 5 minutes before induction and 60 and 120 minutes after induction of anesthesia. Results · The Ppeak values in goup C were significantly lower at all times (P<0.01) and Cdyn at the time of 60 and 120 minutes after induction were significantly higher (P<0.05) than group A. At the time of 60 and 120 minutes after induction, the levels of PaO2 were also increased (P<0.01) while the levels of PaCO2 was significantly decreased (P<0.05) in group C compared to group A and group B respectively. Conclusion · The intermittent positive pressure ventilation of low tidal volume combined with low level of PEEP is a safe and effective mechanical ventilation method for asthma patients under general anesthesia, which can reduce airway peak pressure, enhance pulmonary dynamic compliance and improve the oxygenation index.
