Effect of recombinant human epidermal growth factor combined with sodium hyaluronate eye drops in patients with cataract after multifocal intraocular lens implantation / 中国基层医药

Objective:To investigate the clinical efficacy of recombinant human epidermal growth factor combined with sodium hyaluronate eye drops in the treatment of cataracts after multifocal intraocular lens implantation and its effect on inflammation factors in tears and tear film stability.Methods:A total of 86 patients with cataracts who underwent multifocal intraocular lens implantation at Jinan 2 nd People's Hospital from July 2020 to January 2023 were included in this randomized controlled study. These patients were randomly divided into a control group and a combined group, with 43 patients in each group. Patients in the control group were administered sodium hyaluronate eye drops postoperatively, while patients in the combined group received a combination of recombinant human epidermal growth factor and sodium hyaluronate eye drops. All patients were treated for 1 month. Before and after treatment, the levels of inflammatory factors in tears, tear film stability-related indicators, and corneal endothelial cells were measured and compared between the two groups. Additionally, any adverse reactions experienced by the patients were recorded throughout the treatment period. Results:After treatment, the levels of interleukin-6 and tumor necrosis factor-α in the tear fluid of the combined group were (17.91 ± 2.45) μg/L and (72.14 ± 8.43) μg/L, respectively. These values were significantly lower than those in the control group, which were (24.63 ± 3.05) μg/L and (86.97 ± 9.85) μg/L, respectively ( t = 11.26, 7.50, both P < 0.001). Additionally, the fluorescein staining score for corneal damage in the combined group was (2.34 ± 0.37) points. This was significantly lower than the score of (3.42 ± 0.48) points observed in the control group ( t = 11.69, P < 0.001). Tear break-up time and Schirmer I Test in the combined group were (8.68 ± 0.96) seconds and (9.31 ± 1.04) mm/5 minutes, respectively. These values were significantly higher than those in the control group, which were (7.81 ± 0.89) seconds and (7.14 ± 0.86) mm/5 minutes, respectively ( t = -4.36, -10.54, both P < 0.001). Furthermore, the corneal endothelial cell density and the proportion of hexagonal cells in the combined group were (2 514.09 ± 259.31) counts/mm 2 and (41.67 ± 5.05)%, respectively. These values were significantly higher than those in the control group, which were (2 244.82 ± 253.37) counts/mm 2 and (36.75 ± 4.96)% in the control group ( t = -4.87, -29.45, both P < 0.001). The incidence of adverse reactions in the combined group was 11.63% (5/43), which was significantly higher than 6.98% (3/43) in the control group ( χ2 = 0.55, P > 0.05). Conclusion:The combination of recombinant human epidermal growth factor with sodium hyaluronate eye drops following multifocal intraocular lens implantation in patients with cataracts effectively decreases the levels of inflammatory factors in tear fluid. This treatment regimen also enhances tear film stability, promotes the repair of injured corneal tissue, and is highly safe.

Effect of rehabilitation exercise combined with resistance training on the recovery of patients with pulmonary nodules following surgical intervention / 中国基层医药

Objective:To investigate the effect of rehabilitation exercise combined with resistance training on the postoperative recovery and quality of life among patients with pulmonary nodules.Methods:A randomized controlled study was conducted on 90 patients with pulmonary nodules who underwent thoracoscopic resection of pulmonary nodules at Zhejiang Veteran Hospital between January 2022 and April 2023. Patients were randomly allocated into an observation group and a control group, with 45 patients in each group using the random number table method. The control group underwent routine rehabilitation exercise, whereas the observation group received resistance training combined with routine rehabilitation exercise. All patients were treated for 1 week. The incidence of postoperative complications and the changes in lung function, exercise endurance, and quality of life from baseline levels were compared between the two groups.Results:The incidence of postoperative complications in the observation group was significantly lower than that in the control group [6.7% (3/45) vs. 24.4% (11/45), χ2 = 5.41, P = 0.020). After intervention, the forced expiratory volume in 1 second, maximal voluntary ventilation per minute, and forced vital capacity in the observation group were (83.84 ± 4.35)%, (96.53 ± 3.45) L/min, and (2.87 ± 0.16) L, respectively, which were higher than those in the control group [(78.98 ± 4.01)%, (92.13 ± 3.08) L/min, (2.62 ± 0.19) L, t = -5.51, -6.38, -6.75, all P < 0.001]. Additionally, the modified Medical Research Council dyspnea score in the observation group was (0.42 ± 0.13) points, which was significantly lower than that in the control group [(0.87 ± 0.19) points, t = 13.11, P < 0.001). The modified Barthel index score in the observation group was significantly higher than that in the control group [(89.53 ± 3.67) points vs. (82.94 ± 4.23) points, t = -7.89, P < 0.001). Conclusion:The combination of rehabilitation exercise and resistance training can effectively enhance lung function, exercise endurance, and overall quality of life in patients with pulmonary nodules. Furthermore, this combined therapy markedly reduces postoperative complications.

360-degree pedicled inverted internal limiting membrane flap technique without face-down posturing for large idiopathic macular holes: a retrospective case series / Técnica de flap invertido de membrana limitante interna 360 graus pediculado sem posicionamento de cabeça para buracos maculares idiopáticos grandes: série retrospectiva de casos

ABSTRACT Purpose: This study aimed to determine closure rates of large idiopathic macular holes treated with pars plana vitrectomy and 360-degree pedicled inverted internal limiting membrane flap without face-down posturing and define visual improvement, types of macular hole closure, and external retina integrity as secondary outcomes. Methods: This retrospective case series analyzed all patients who were treated by vitrectomy, 360-degree pedicled inverted internal limiting membrane flap, and gas tamponade, without face-down posturing postoperatively. Age, sex, time of visual acuity reduction, other ocular pathologies, and lens status were collected. The best-corrected visual acuity and optical coherence tomography results were recorded during pre- and postoperative follow-up examinations (15 days and 2 months after surgery). Results: This study enrolled 20 eyes of 19 patients, and the mean age was 66 years. Optical coherence tomography performed 2 months after surgery revealed hole closure in 19 (95%) eyes. The median best-corrected visual acuity improved from +1.08 preoperatively to +0.66 LogMAR 2 months postoperatively (p<0.001), with a median of 20 letters of visual improvement (0.4 LogMAR) on the Early Treatment Diabetic Retinopathy Study chart. V (47.36%)- and U (52.63%)-types of closure were observed. Conclusion: The 360-degree pedicled inverted internal limiting membrane flap technique, without face-down posturing, provided a high closure rate (95%), external layer recovery, and V- and U-type foveal closure contours, in addition to visual improvement in most cases of large macular holes (even macular holes >650 μm). This technique may be a viable alternative to patients in whom traditional postoperative face-down positioning for large macular hole treatment is not possible.

RESUMO Objetivo: Determinar as taxas de fechamento de buracos maculares idiopáticos grandes tratados com vitrectomia posterior e técnica de flap invertido 360 graus pediculado de membrana limitante interna, sem posicionamento de cabeça pós-operatório e definir melhora visual, tipos de fechamento do buraco macular e integridade das camadas retinianas externas como objetivo secundário. Métodos: Este estudo foi uma série retrospectiva de casos. Todos os pacientes foram submetidos a vitrectomia com flap invertido 360 graus pediculado de membrana limitante interna e tamponamento com gás, sem posição de cabeça no pós-operatório. Idade, gênero, tempo de redução da acuidade visual, outras patologias oculares e status do cristalino foram compilados. Medida de melhor acuidade visual corrigida e tomografia de coerência óptica foram registradas durante as visitas de pré e pós-operatório (15 dias e 2 meses após cirurgia). Resultados: Vinte olhos de 19 pacientes foram incluídos neste estudo. A idade média foi de sessenta e seis anos. Um total de 19 olhos (95%) atingiu fechamento do buraco, observado através das imagens de tomografia de coerência óptica após 2 meses de cirurgia. Melhor acuidade visual corrigida média aumentou +1,08 pré-operatória para +0,66 LogMAR em 2 meses de cirurgia (p<0,001), com média de 20 letras de melhora visual (0,4 LogMAR) na tabela do Early Treatment Diabetic Retinopathy Study. Dois tipos de fechamento do buraco foram observados: V (47,36%) e U (52,63%). Conclusão: A técnica de flap invertido 360 graus pediculado de membrana limitante interna, sem posicionamento de cabeça no pós-operatório promoveu elevada taxa de fechamento (95%), reestabelecimento das camadas retinianas externas, fechamento com contorno foveal dos tipos V e U, além de melhora visual na maioria dos casos de BMI gran des (mesmo nos buracos maiores que 650 μm). Esta técnica pode representar uma alternativa para o tratamento de buracos maculares grandes em pacientes impossibilitados de cumprir o tradicional posicionamento de cabeça pós-operatório.

Evaluation of early ocular discomfort after glaucoma surgery: trabeculectomy versus Ahmed glaucoma valve implantation

ABSTRACT Purpose: This study aims to compare the initial ocular discomfort symptoms resulting from trabeculectomy and Ahmed glaucoma valve implantation surgeries. Methods: A prospective comparative study was conducted. The evaluation of ocular discomfort employed a questionnaire designed to identify the frequency and severity of distinct symptoms: ocular pain, general discomfort, tearing, foreign body sensation, and burning. This questionnaire was administered prior to surgery as a baseline, and subsequently at 7, 30, and 90 days post-surgery. Simultaneously, the Ocular Surface Disease Index (OSDI) was applied at these same time intervals. Results: The study encompassed a total of 17 patients (9 undergoing trabeculectomy and 8 undergoing Ahmed glaucoma valve implantation). The Ahmed glaucoma valve implantation group exhibited higher tearing levels at baseline (p=0.038). However, no statistically significant differences in symptoms were observed between the two surgeries at 7 and 30 days post-surgery. At the 90-day mark following surgery, patients who had undergone trabeculectomy reported a significantly higher foreign body sensation (p=0.004). Although OSDI scores did not differ between groups at baseline, the trabeculectomy group showed significantly higher OSDI scores than the Ahmed glaucoma valve implantation group at 7, 30, and 90 days after surgery (p<0.05). Conclusion: Post-surgery, patients who had undergone trabeculectomy experienced increased foreign body sensation. Trabeculectomy appears to cause greater early postoperative ocular discomfort compared to the Ahmed glaucoma valve implantation group.

Predisposing and precipitating factors for the development of postoperative delirium in critically ill patients in a university intensive care unit / Fatores predisponentes e precipitantes para o desenvolvimento de delirium pós-operatório em pacientes críticos de uma unidade intensiva universitária / Factores predisponentes y precipitantes para el desarrollo del delirium postoperatorio en pacientes críticos de una unidad intensiva universitaria

Abstract Objective: to detect the incidence of postoperative delirium in critically ill patients admitted to a surgical intensive care unit and to evaluate the predisposing and precipitating factors associated with postoperative delirium in critically ill patients admitted to a surgical intensive care unit. Method: this is a prospective cohort study of 157 critically ill surgical patients. Fisher's exact test and Chi-square test were used for the association between factors and the occurrence of delirium, the Wilcoxon test for numerical variables, and the logistic regression model for the analysis of predisposing and precipitating factors. Results: the incidence of delirium was 28% (n=44). Age was a significant predisposing factor (p=0.001), followed by the length of surgery (p<0.001), blood transfusion (p=0.043), administration of crystalloids (p=0.008), and anti-inflammatory drugs (p=0.037), which were the precipitating factors identified. The best-adjusted models were: age, length of surgery, non-administration of anti-emetics, use of sufentanil, and blood transfusion. Conclusion: delirium is a frequent condition in critically ill adults undergoing surgery and the existence of precipitating and predisposing factors is relevant to the outcome, with the anesthetic-surgical procedure as the catalyst event.

Is Incentive Spirometry Superior to Standard Care in Postoperative Cardiac Surgery on Clinical Outcomes and Length of Hospital and Intensive Care Unit Stay? A Systematic Review with Meta-Analysis

ABSTRACT Introduction: Cardiac surgery is a frequent surgical procedure and may present a high risk of complications. Among the prophylactic strategies studied to decrease the rates of negative outcomes, respiratory care seems to reduce pulmonary complications. Incentive spirometry (IS) is a low-cost, respiratory exercise technique, used for the prevention and treatment of postoperative pulmonary complications (PPC). The aim of this review was to evaluate whether IS is superior to respiratory care, mobilization exercises, and noninvasive ventilation on PPC, and clinical outcomes. Methods: Systematic review. Medical Literature Analysis and Retrieval System Online (or MEDLINE®), Embase®, Cochrane Central Register of Controlled Trials (or CENTRAL), Physiotherapy Evidence Database (or PEDro), Cumulative Index of Nursing and Allied Health (or CINAHL®), Latin American and Caribbean Health Sciences Literature (or LILACS), Scientific Electronic Library Online (or SciELO), Allied, Scopus®, and OpenGrey databases, clinical trial registration sites, conferences, congresses, and symposiums were searched. Results: Twenty-one randomized trials and one quasi-randomized trial (1,677 participants) were included. For partial pressure of oxygen (PaO2), IS was inferior to respiratory care (mean difference [MD] -4.48; 95% confidence interval [CI] -8.32 to -0.63). Flow-oriented IS was inferior to respiratory care on PaO2 (MD -4.53; 95% CI -8.88 to -0.18). However, compared to respiratory care, flow-oriented IS was superior on recovery vital capacity. Conclusions: This meta-analysis revealed that IS was not superior to standard respiratory care for PPCs and clinical outcomes, therefore its use should not be widely recommended until further studies with high quality be performed to ensure this clinical guidance.

Relação entre a Complacência Pulmonar Estática e a Falha de Extubação em Pacientes Pós-Operatório de Cirurgia Cardíaca / Relationship between Static Lung Compliance and Extubation Failure in Postoperative Cardiac Surgery Patients

Resumo Fundamento: Pouco explorada na decisão de extubação no pós-operatório de cirurgia cardíaca, a complacência pulmonar estática seriamente afetada no procedimento cirúrgico pode levar à insuficiência respiratória e à falha na extubação. Objetivo: Avaliar a complacência pulmonar estática no pós-operatório de cirurgia cardíaca e relacionar sua possível redução aos casos de falha na extubação dos pacientes submetidos ao método fast-track de extubação. Métodos: Foram incluídos pacientes que realizaram cirurgia cardíaca com uso de circulação extracorpórea (CEC) em um hospital universitário estadual admitidos na UTI sob sedação e bloqueio residual. Tiveram sua complacência pulmonar estática avaliada no ventilador mecânico por meio do software que utiliza o least squares fitting (LSF) para a medição. No período de 48 horas após a extubação os pacientes foram observados respeito à necessidade de reintubação por insuficiência respiratória. O nível de significância adotado para os testes estatísticos foi de 5%, ou seja, p<0,05. Resultados: Obtiveram sucesso na extubação 77 pacientes (75,49%) e falharam 25 (24,51%). Os pacientes que falharam na extubação tiveram a complacência pulmonar estática mais baixa quando comparados aos que tiveram sucesso (p<0,001). Identificamos o ponto de corte para complacência por meio da análise da curva Receiver Operating Characteristic Curve (ROC) sendo o ponto de corte o valor da complacência <41ml/cmH2O associado com maior probabilidade de falha na extubação (p<0,001). Na análise de regressão múltipla, verificou-se a influência da complacência pulmonar (dividida pelo ponto de corte da curva ROC) com risco de falha 9,1 vezes maior para pacientes com complacência <41ml/cmH2O (p< 0,003). Conclusões: A complacência pulmonar estática <41ml/cmH2O é um fator que compromete o sucesso da extubação no pós-operatório de cirurgia cardíaca.

Abstract Background: Static lung compliance, which is seriously affected during surgery, can lead to respiratory failure and extubation failure, which is little explored in the decision to extubate after cardiac surgery. Objective: To evaluate static lung compliance in the postoperative period of cardiac surgery and relate its possible reduction to cases of extubation failure in patients submitted to the fast-track method of extubation. Methods: Patients undergoing cardiac surgery using cardiopulmonary bypass (CPB) at a state university hospital admitted to the ICU under sedation and residual block were included. Their static lung compliance was assessed on the mechanical ventilator using software that uses least squares fitting (LSF) for measurement. Within 48 hours of extubation, the patients were observed for the need for reintubation due to respiratory failure. The level of significance adopted for the statistical tests was 5%, i.e., p<0.05. Results: 77 patients (75.49%) achieved successful extubation and 25 (24.51%) failed extubation. Patients who failed extubation had lower static lung compliance compared to those who succeeded (p<0.001). We identified the cut-off point for compliance through analysis of the Receiver Operating Characteristic Curve (ROC), with the cut-off point being compliance <41ml/cmH2O associated with a higher probability of extubation failure (p<0.001). In the multiple regression analysis, the influence of lung compliance (divided by the ROC curve cut-off point) was found to be 9.1 times greater for patients with compliance <41ml/cmH2O (p< 0.003). Conclusions: Static lung compliance <41ml/cmH2O is a factor that compromises the success of extubation in the postoperative period of cardiac surgery.

Post-operative nausea and vomiting prophylaxis: A meta-review on systematic reviews and meta-analyses

Introduction: Postoperative nausea and vomiting (PONV) are common complications in surgical patients undergoing general anesthesia, and multiple strategies have been suggested to prevent them. Objective: To describe the available evidence on the effectiveness of pharmacological and non-pharmacological strategies for preventing PONV in adults undergoing surgery under general anesthesia, as reported in previous meta-analyses and systematic reviews. Methodology: An overview of systematic reviews and meta-analyses was conducted. Searches were performed in PubMed, EBSCO, EMBASE, Cochrane Database, Science Direct, and Scopus, without restrictions as to gender, clinical condition, or date of publication, including articles in Spanish, French, and English only. Two reviewers independently and in duplicate did the screening, data extraction, quality evaluation, and risk of bias assessment according to AMSTAR-2. The PRISMA and PRIOR statements were followed for reporting. PROSPERO registration number CRD42021251999. Results: Out of 80 candidate articles, three were viable for meta-analysis. 1.5 mg to 18 mg doses of Dexamethasone showed a significant reduction in the risk of PONV, with a RR of 0.48 (95 % CI 0.41-0.57; p<0.001), I2=63 % (p=0.07), and a NNTc of 5 and 7. Other effective strategies included the use of acoustic stimulation/acupuncture/acupressure, 5HT3 antagonists, NK1 antagonists, gabapentinoids, haloperidol, droperidol, metoclopramide, midazolam, mirtazapine, among others. The risk of publication bias was low. Conclusion: Different strategies are effective for PONV prophylaxis in surgeries under general anesthesia. Dexamethasone shows the best available evidence at the moment. The documented methodological quality suggests the need for better studies to establish the effectiveness of the strategies.

Early or Delay? The Most Suitable Rehabilitation Protocol for "No Man's Land" Injury: Meta-Analysis with Trial Sequential Analysis - 20 Years Trends / Precoce ou tardio? O protocolo de reabilitação mais adequado para lesão na região 'terra de ninguém': Metanálise com análise sequencial de ensaios - Tendências de 20 anos

Abstract Objective The aim of this study is to analyze various rehabilitation protocol and determine which methods will yield a better outcome. Methods The database reports were searched within 1990 until 2020, using PubMed, Cochrane library database, Ovid, Medline, and the other several published trials. A statistical analysis was made from Review Manager and Trial Sequential Analysis (TSA). Result The mean of re-rupture rate is 3.3% (n= 8) in the combination protocol until 8% (n= 48) in CAM protocol. Meta-analyses found no significant difference between Kleinert vs CAM in re-rupture rate. Also no significant difference in Duran vs CAM in rerupture rate. In Trial Sequential Analysis (TSA), the z-curve does not cross both of the trial sequential boundaries, a further trial with larger sample will be required. The TSA of flexion contracture CAM vs Kleinert was indicated that CAM protocol may be superior than Kleinert to reduce the incidence of flexion contracture. For the range of mean flexion contracture 6.6% (n= 18) in CAM to 23.6% (n= 76) in Kleinert protocol. Conclusion Current meta-analysis proposed that the combination technique will result less re-rupture incidence and better functional outcome in flexor zone II injuries than other techniques. The CAM method also results less flexion contracture than others. However, a further meta-analyses with larger sample trials will be required to confirm this review's conclusion.

Resumo Objetivo O objetivo deste estudo é analisar vários protocolos de reabilitação e determinar quais métodos produzem um melhor resultado. Métodos Os relatórios dos bancos de dados foram pesquisados entre 1990 e 2020, usando PubMed, banco de dados da biblioteca Cochrane, Ovid, Medline e vários outros ensaios publicados. Uma análise estatística foi feita a partir do Review Manager e Trial Sequential Analysis (TSA). Resultado A taxa média de re-ruptura é de 3,3% (n = 8) no protocolo combinado, e até 8% (n = 48) no protocolo de Movimento Ativo Controlado (MAC). As metanálises não encontraram diferença significativa entre Kleinert vs MAC na taxa de re-ruptura. Também não há diferença significativa entre Duran e MAC na taxa de re-ruptura. Na Trial Sequential Analysis (TSA), a curva z não cruza ambos os limites sequenciais de ensaio, será necessário um ensaio adicional com amostra maior. A TSA de contratura em flexão MAC vs Kleinert indicou que o protocolo MAC pode ser superior ao Kleinert para reduzir a incidência de contratura em flexão. Para a faixa de contratura média em flexão de 6,6% (n = 18) no MAC a 23,6% (n = 76) no protocolo Kleinert. Conclusão A metanálise atual propôs que a técnica combinada resultará em menor incidência de re-ruptura e melhor resultado funcional em lesões da zona flexora II do que outras técnicas. O método MAC também resulta em menos contratura em flexão do que outros. No entanto, serão necessárias mais metanálises com estudos com amostras maiores para confirmar a conclusão desta revisão.

Assessment of pain and quality of life in patients undergoing cardiac surgery: a cohort study

SUMMARY OBJECTIVE: This study aimed to evaluate postoperative pain and quality of life in patients undergoing median sternotomy. METHODS: A cohort study was carried out on a sample of 30 patients who underwent elective cardiac surgery by longitudinal median sternotomy. Patients were interviewed at Intensive Care Unit discharge and hospital discharge, when the Visual Numeric Scale and the Brief Pain Inventory were applied, and 2 weeks after hospital discharge, when the World Health Organization Quality of Life-Bref questionnaire was administered. The normality of the results was analyzed by the Shapiro-Wilk test, and Wilcoxon Rank Sum and McNemar tests were utilized for the analysis of numerical and categorical variables. For correlation between numerical variables, Spearman's linear correlation test was applied. To compare numerical variables, Mann-Whitney U and Kruskal-Wallis tests were applied. Differences between groups were considered significant when the p-value was <0.05. RESULTS: Between Intensive Care Unit and hospital discharge, there was a reduction in median pain intensity assessed by the Visual Numeric Scale from 5.0 to 2.0 (p<0.001), as well as in eight Brief Pain Inventory parameters: worst pain intensity in the last 24 h (p=0.001), analgesic relief (p=0.035), and pain felt right now (p=0.009); and in interference in daily activities (p<0.001), mood (p=0.017), ability to walk (p<0.001), relationship with other people (p=0.005), and sleep (p=0.006). Higher pain intensity at Intensive Care Unit discharge was associated with worse performance in the psychological domain of quality of life at out-of-hospital follow-up. CONCLUSION: Proper management of post-sternotomy pain in the Intensive Care Unit may imply better quality of life at out-of-hospital follow-up.

Relationship between Degree of Dependency and Hospitalization Time of Surgical Patients / Relación entre grado de dependencia y el tiempo de hospitalización de pacientes quirúrgicos / Relação entre grau de dependência e tempo de internação de pacientes cirúrgicos atendidos em hospital regional

Objective. This work sought to establish the relationship between the degree of dependency with hospitalization time of patients intervened surgically in a regional hospital of Peru. Methods. The study was analytical, cross-sectional with retrospective data collection, studying 380 patients treated in the surgical service at Regional hospital Docente in the municipality of Cajamarca (Peru). The patients' demographic and clinical information was obtained from the daily care records in the hospital's surgery service. The univariate description was conducted through absolute and relative frequencies and confidence intervals for proportions at 95%; for the association between the degree of dependency and hospitalization time Log Rank (Mantel-Cox) ­ Chi-square was applied, as well as the Kaplan-Meier survival analysis, with statistical significance of p<0.05. Results. The study had 53.4% male patients, with mean age of 35.3 years, referrals from operating room (64.7%), surgery specialty (66.6%) and the most-frequent surgical intervention was appendectomy (49.7%). Mean hospitalization time was 10 days; 88.1% of the patients had grade-II dependency. The degree of patient dependency had a significant impact on the days of post-surgery hospitalization with direct relationship between both variables (p=0.038). Conclusion. Hospitalization time is determined by the degree of dependency of patients subjected to a surgical intervention; thereby, it is fundamental to anticipate all the necessary resources for proper care management.

Objective:To investigate the clinical application value of modified prescription of Bushen Huoxue Decoction combined with Zhengguling Capsule after surgical treatment of osteoporotic fracture. Methods:Eighty patients undergoing surgical treatment of osteoporotic fractures in Jiamusi Orthopedic Hospital from January 2019 to January 2021 were included in this study. They were randomly divided into a control group ( n = 40, receiving routine western medicine treatment) and a study group ( n = 40, receiving adjuvant treatment with modified prescription of Bushen Huoxue Decoction combined with Zhengguling Capsule based on routine western medicine treatment). All patients were treated for 6 consecutive months. The Fugl-Meyer Assessment scale score of motor function, traditional Chinese medicine symptom score, modified Barthel Index (MBI) score, bone mineral density T value at different treatment time points, clinical efficacy, and incidence of adverse reactions were compared between the two groups before and after treatment. Results:At 1, 2, 3 and 6 months of treatment, the T value of bone mineral density in the study group was significantly higher than that in the control group (all P < 0.001). At the end of treatment, the modified Barthel Index and the Fugl-Meyer Assessment scale score in the study group were (78.05 ± 4.26) points and (88.53 ± 2.35) points, which were significantly greater than (70.02 ± 6.58) points and (82.75 ± 2.44) points in the control group ( t = 6.49, 13.92, both P < 0.05). At the end of treatment, the symptom score in the study group was significantly lower than that in the control group ( P < 0.001). Total response rate in the study group was significantly higher than that in the control group [97.5% (39/40) vs. 80.0% (32/40), χ2 = 6.14, P < 0.05]. There was no significant difference in incidence of adverse reactions between the two groups ( P > 0.05). Conclusion:Modified prescription of Bushen Huoxue Decoction combined with Zhengguling Capsule can effectively improve motor ability and increase bone mineral density T value in patients after surgical treatment for osteoporotic fracture.

Prolonging negative pressure drainage time to prevent salivary fistula after parotidectomy / 中国基层医药

Objective:To investigate the effect of prolonged negative pressure drainage time after parotidectomy and analyze its relationship with the incidence of postoperative salivary fistula.Methods:The clinical data of 94 patients with benign parotid gland tumors who received treatment in the Department of Otolaryngology-Head and Neck Surgery of The First Affiliated Hospital of Xiamen University from July 2021 to June 2022 were retrospectively analyzed. These patients were divided into an observation group and a control group ( n = 47 per group). In the observation group, the negative pressure drainage tube was removed after 1 week of simple negative pressure drainage, while in the control group, conventional local bandaging of the parotid gland was performed for 2 weeks, and negative pressure drainage was given for 2-3 days. Postoperative drainage volume, pain degree, and the incidence of salivary fistula were recorded for each group. Results:The total drainage volume in the observation group was (77.93 ± 23.83) mL, which was significantly greater than (47.06 ± 24.71) mL in the control group ( t = 6.17, P < 0.001). The Visual Analogue Scale score in the observation group was (3.021 ± 1.07) points, which was significantly lower than (7.53 ± 1.27) points in the control group ( t = 18.63, P < 0.001). The incidence of postoperative salivary fistula in the observation group was 2.1% (1/47), which was significantly lower than 17.0% (8/47) in the control group ( χ2 = 4.42, P = 0.035). Conclusion:Simple prolongation of negative pressure drainage time can achieve full drainage, improve the quality of life of patients after parotidectomy and reduce the occurrence of postoperative salivary fistula, which is worthy of clinical promotion.

Comparative efficacy of awake prone positioning combined with standardized nursing care and standardized nursing care in the prevention of early postoperative pulmonary complications in elderly patients with hip fracture / 中华创伤杂志

Objective:To compare the effectiveness of awake prone positioning (APP) care combined with standardized nursing and standardized nursing care in the prevention of early postoperative pulmonary complications (PPCs) in elderly patients with hip fracture.Methods:A retrospective cohort study was conducted to analyze the clinical data of 84 elderly patients with hip fracture Admitted to Zhongda Hospital Affiliated to Southeast University from February 2021 to August 2021. There were 31 males and 53 females, aged 67-96 years [(82.3±6.3)years]. Fracture types were femoral neck fracture ( n=45) and intertrochanteric fracture ( n=39). Surgical procedures included closed reduction internal fixation ( n=39), hip hemiarthroplasty ( n=35), and total hip arthroplasty ( n=10). Among them, 42 patients received standardized nursing care and APP intervention (APP combined with standardized nursing care group), while the remaining 42 patients received standardized nursing care only (standardized nursing care group). The incidence rate of PPCs (including pneumonia, respiratory failure, pleural effusion, atelectasis and pulmonary edema) within 30 postoperative days, arterial oxygen pressure (PaO 2), arterial carbon dioxide pressure (PaCO 2), arterial oxygen saturation (SaO 2) on the 4th postoperative day, difference in PaO 2 between the 4th postoperative day and emergency visit, clinical pulmonary infection score (CPIS) on the 4th postoperative day, and number of adverse events related to APP were compared between the two groups. Results:All the patients were followed up for 30-90 days [(86.1±16.5)days]. The incidence rates of PPCs and type 1 postoperative respiratory failure in the APP combined with standardized nursing care group were 16.7% (7/42) and 4.8% (2/42), and were 35.7% (15/42) and 21.4% (9/42) in the standardized nursing care group (all P<0.05). The PaO 2 and SaO 2 on the 4th postoperative day, and difference in PaO 2 between the 4th postoperative day and emergency visit were (82.0±8.8)mmHg, 0.96±0.01, and 3.2 (-1.9, 8.0)mmHg in the APP combined with standardized nursing care group, and were (74.3±12.1)mmHg, 0.94±0.03, and -7.6 (-17.2, 1.1)mmHg in the standardized nursing care group (all P<0.01). The CPIS on the 4th postoperative day was 2.0 (1.0, 3.0)points in the APP combined with standardized nursing care group and 4.0 (1.0, 7.0)points in the standardized nursing care group ( P<0.05). No statistically significant differences were observed in the incidence of pneumonia, type I respiratory failure, pleural effusion, atelectasis and pulmonary edema within 30 postoperative days, as well as PaCO 2 on the 4th postoperative day between the two groups (all P>0.05). None of the patients experienced adverse events related to APP. Conclusion:For elderly patients with hip fracture, compared with standardized nursing care, application of APP combined with standardized nursing care can significantly decrease the incidence rate of early PPCs, especially type I respiratory failure, and improve postoperative oxygenation.

Medidas para optimizar cuidados post rinoplastia. Revisión sistemática de la literatura / Measures to optimize rhinoplasty post operative care, systematic review of the literature

Introducción: El cuidado postoperatorio de la rinoplastia ha evolucionado, paralelamente, al desarrollo de la técnica quirúrgica. Existen varias recomendaciones, sin embargo, hay una gran variabilidad interprofesional de las indicaciones post quirúrgicas. Objetivo: Realizar una revisión sistemática de la literatura científica sobre los cuidados post operatorios de la rinoplastia. Material y Método: Para la realización de este estudio se llevaron a cabo búsquedas en PubMed y en Cochrane Database of Systematic Reviews con los perfiles: ([rhinoplasty] AND [post operative care]) y ([rhinoplasty] AND [post surgical care]). Se seleccionaron los artículos publicados en los últimos 10 años, desde 2013 hasta 2023, ambos inclusive. Resultados: Los documentos analizados recogen la evidencia de los diferentes métodos de cuidados post quirúrgicos en rinoplastia. Estos confirman la utilización de corticoides en el período postoperatorio, así como el reposo en 90° y exponen la variabilidad interprofesional que existe en el protocolo postquirúrgico de esta cirugía. Conclusión: El uso de corticoides y el reposo en 90° disminuyen las complicaciones postquirúrgicas de la rinoplastia. Debe existir una clara información sobre lo que el paciente debe esperar post cirugía. El uso de opioides debe ser restringido y la analgesia debe ser multimodal. Es preciso realizar estudios futuros con mayor nivel de evidencia y tener protocolos uniformes para la práctica clínica.

Introduction: The postoperative care of rhinoplasty has evolved along with the development of the surgical technique. There are several recommendations, however there is enormous interprofessional variability of post-surgical indications. Aim: To carry out a systematic review of the scientific literature on rhinoplasty postoperative care. Material and Method: To carry out this study, searches were carried out in PubMed and in the Cochrane Database of Systematic Reviews with the profiles: ([rhinoplasty] AND [post operative care]) and ([rhinoplasty] AND [post surgical care]). Articles published in the last 10 years were selected, from 2013 to 2023, both inclusive. Results: The documents analyzed collect the evidence of the different methods of post-surgical care in rhinoplasty, they confirm the use of corticosteroids in the postoperative period as well as rest at 90° and expose the interprofessional variability that exists in the post-surgical protocol of this surgery. Conclusion: The use of corticosteroids and rest at 90° reduce the post-surgical complications of rhinoplasty. There must be clear information about what the patient should expect post surgery. The use of opioids must be restricted and analgesia must be multimodal. It is necessary to carry out future studies with a higher level of evidence and have uniform protocols for clinical practice.

Coronary Artery Bypass Grafting: A Comparative Exercise between Patients from the BYPASS Registry and Patients from a University Hospital

ABSTRACT Introduction: The coronary artery bypass grafting (CABG) data provided by the Brazilian Registry of Cardiovascular Surgeries in Adults (BYPASS) Registry is a Brazilian reality. Objective: To carry out a comparative exercise between the BYPASS Registry published data and data from patients operated on in a randomly chosen period (2013-2015) at Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo (HCFMRP-USP). Methods: This is a retrospective study reviewing 173 electronic medical records of CABG patients from the HCFMRP-USP. These data were compared with the BYPASS Registry published data. Chi-square test was used to verify the changes within the prevalence of adequate/inadequate biochemical tests before and after surgery. The sample was divided into groups consistent with cardiopulmonary bypass (CPB) time (CPB ≤ 120 minutes and CPB > 120 minutes). For the complications, prevalence by the chi-square test was adopted. Significant P-values are < 0.05. Results: The comparative operative data of the BYPASS Registry and the HCFMRP-USP patients were quite similar, except for the isolate use of only arterial grafts, which was more frequent on HCFMRP-USP patients (30.8% vs. 15.9%), and the use of radial artery, also more frequent on HCFMRP-USP patients (48.8% vs. 1.1%) Conclusion: The comparative study suggested that the BYPASS Registry should be a reference for CABG quality control.

Can Posterior Pericardial Incision Truly Improve Postoperative Complications After Cardiac Surgery? A Systematic Review and Meta-Analysis

ABSTRACT Introduction: Postoperative atrial fibrillation (POAF) and pericardial effusion are important factors affecting prognosis after cardiac surgery. Recently, it has been reported that posterior pericardiotomy (PP) can effectively prevent the occurrence of POAF and pericardial effusion. To validate these conclusions and guide clinical practice, we conducted a systematic review with meta-analysis. Methods: We searched multiple databases for manuscripts published before July 2022 on the use of PP to prevent POAF and pericardial effusion and included only randomized controlled trials. The main outcome was atrial fibrillation after coronary artery bypass grafting, and secondary outcomes were included. Results: This meta-analysis included 14 randomized controlled trials with a total of 2275 patients. Meta-analysis showed that the incidence of POAF after cardiac surgery in the PP group was significantly lower than that in the control group (risk ratio=0.48; 95% confidence interval=0.33~0.69; P<0.00001). PP effectively reduced postoperative pericardial effusion (risk ratio=0.34, 95% confidence interval=0.21-0.55; P<0.00001). Conclusion: PP has shown good results in preventing POAF, pericardial effusion, and other complications, which indicates that PP is a safe and effective surgical method, but attention still needs to be paid to the potential risk of coagulation dysfunction caused by PP.
