Effectiveness of preoperative and perioperative pulmonary rehabilitation nursing program for the management of patients undergoing thoracic surgery: A systematic review and meta-analysis.
BACKGROUND & OBJECTIVE
Several studies have investigated the effectiveness of preoperative or perioperative pulmonary rehabilitation in thoracic surgery patients, but the results are inconsistent and inconclusive. This study attempts to summarize the existing data on the effect of the preoperative and perioperative pulmonary rehabilitation nursing program for the management of patients undergoing thoracic surgery.
METHODS
Systematic search was done in PubMed Central, SCOPUS, EMBASE, MEDLINE, Google Scholar, and ScienceDirect for papers published until December 2022 and reporting data of postoperative complications and pulmonary health status in patients undergoing thoracic surgery and receiving preoperative or perioperative pulmonary rehabilitation nursing intervention or standard care. Meta-analysis was done by random-effects model and pooled standardised mean differences (SMD) or odds ratios (OR) along with 95% confidence intervals (CIs) were reported.
RESULTS
Eighteen studies were included and analysed. Pooled SMD was 0.44 (95%CI: -0.21 to 1.08) for forced expiratory volume (FEV-1), -0.34 (95%CI: -0.94 to 0.26) for peak expiratory flow (PEF), 0.61 (95%CI: -0.60 to 1.81) for forced vital capacity (FVC), 0.42 (95%CI: -0.13 to 0.98) for diffusing capacity of carbon monoxide (DLCO). Pooled SMD for length of hospital stay was -0.64 (95%CI: -1.09 to -0.19). Pooled OR was 0.87 [95%CI: 0.32 to 2.37] for all-cause mortality, 0.35 [95%CI: 0.25 to 0.50] for postoperative pulmonary complications, 0.98 [95%CI: 0.45 to 2.12] for respiratory failure, 0.52 [95%CI: 0.38 to 0.78] for pneumonia and 0.50 [95%CI: 0.33 to 0.76] for atelectasis.
CONCLUSION
Perioperative pulmonary rehabilitation nursing program is effective in reducing the postoperative lung complications and shortening the length of hospital stay in patients undergoing thoracic surgery.

Review
BACKGROUND
Postoperative pulmonary complications (PPCs) are associated with postoperative mortality and prolonged hospital stay. Although intraoperative mechanical ventilation (MV) is a risk factor for PPCs, strategies addressing weaning from MV are understudied. In this systematic review, we evaluated weaning strategies and their effects on postoperative pulmonary outcomes.
METHODS
Our protocol was registered on PROSPERO (CRD42022379145). Eligible studies included randomised controlled trials and observational studies of adults weaned from MV in the operating room. Primary outcomes included atelectasis and oxygenation; secondary outcomes included lung volume changes and PPCs. Risk of bias was assessed using the Cochrane Risk of Bias (RoB2) tool, and quality of evidence with the GRADE framework.
RESULTS
Screening identified 14 randomised controlled trials including 1719 patients; seven studies were limited to the weaning phase and seven included interventions not restricted to the weaning phase. Strategies combining pressure support ventilation (PSV) with positive end-expiratory pressure (PEEP) and low fraction of inspired oxygen (FiO) improved atelectasis, oxygenation, and lung volumes. Low FiO improved atelectasis and oxygenation but might not improve lung volumes. A fixed-PEEP strategy led to no improvement in oxygenation or atelectasis; however, individualised PEEP with low FiO improved oxygenation and might be associated with reduced PPCs. Half of included studies are of moderate or high risk of bias; the overall quality of evidence is low.
CONCLUSIONS
There is limited research evaluating weaning from intraoperative MV. Based on low-quality evidence, PSV, individualised PEEP, and low FiO may be associated with reduced postoperative pulmonary outcomes.

Effect of ultrasound-guided lung recruitment to reduce pulmonary atelectasis after non-cardiac surgery under general anesthesia: a systematic review and meta-analysis of randomized controlled trials.
BACKGROUND
At present, the application of bedside lung ultrasound is increasing gradually, but there is no relevant expert consensus or guidance for its evaluation in the field of perioperative anesthesia. Through this meta-analysis, we tried to determine the impact of ultrasound-guided lung recruitment maneuvers (LRM) on perioperative patients.
METHODS
We searched PubMed, Cochrane Library database, Embase, and Clinical Trials gov for the randomized controlled trials (RCTs) published up to December 31, 2022. The primary outcome was the incidence of postoperative atelectasis. Secondary outcomes included lung ultrasound score (LUS) and LUS of each part. A total of 443 patients were examined in nine randomized controlled trials.
RESULTS
The incidence of atelectasis after surgery in patients with ultrasound-guided LRM was less (RR 0.31; 95% CI 0.25-0.40; p < 0.05). The LUS (WMD - 6.24; 95% CI - 6.90-5.59; p < 0.05) and the LUS of each part (LUS in front lung region (WMD - 2.00; 95% CI - 2.49 to - 1.51; p < 0.05); LUS in lateral lung region (WMD - 2.50; 95% CI - 3.20 to - 1.80; p < 0.05); LUS in posterior lung region (WMD - 3.24; 95% CI - 4.23 to - 2.24; p < 0.05)) in patients with ultrasound-guided LRM were lower.
CONCLUSION
Ultrasound-guided lung recruitment maneuvers have been shown to be a promising approach for improving perioperative lung ventilation by increasing aeration while mitigating the development of atelectasis. In comparison to non-ultrasound-guided methods, this technique has exhibited superior effects.

INTRODUCTION
Cervical spinal cord injury (CSCI) patients on mechanical ventilation often lack standardized guidelines for optimal ventilatory support. This study reviews existing literature to compare outcomes between high tidal volume (HTV) and low tidal volume (LTV) strategies in this unique patient population.
METHODS
We searched for studies published up to August 30, 2023, in five databases, following a PECO/PICO strategy. We found six studies for quantitative analysis and meta-analyzed five studies.
RESULTS
This meta-analysis included 396 patients with CSCI and mechanical ventilation (MV), 119 patients treated with high tidal volume (HTV), and 277 with low tidal volume (LTV). This first meta-analysis incorporates the few studies that show contradictory findings. Our meta-analysis shows that there is no significant statistical difference in developing VAP between both comparison groups (HTV vs. LTV) (OR 0.46; 95% CI 0.13 to 1.66; > 0.05; : 0%), nor are there differences between the presence of other pulmonary complications when treating with HTV such as acute respiratory distress syndrome (ARDS), atelectasis, onset of weaning.
CONCLUSION
In patients with CSCI in MV, the use of HTV does not carry a greater risk of pneumonia compared to LTV; in turn, it is shown as a safe ventilatory strategy as it does not establish an increase in other pulmonary complications such as ARDS, atelectasis, the onset of weaning nor others associated with volutrauma. It is necessary to evaluate the role of HTV ventilation in this group of patients in primary RCT-type studies.

Silent sinus syndrome (SSS) and chronic maxillary atelectasis (CMA) represent an overlapping clinical entity, both likely lying on the spectrum of one disease process. There is widespread inconsistency of diagnosis in the literature of reported cases of SSS and CMA. We propose a novel, comprehensive staging system to simplify diagnosis and inform management.

Review
BACKGROUND
Nitrous oxide (NO) is a common adjuvant to general anaesthesia. It is also a potent greenhouse gas and causes ozone depletion. We sought to quantify the influence of NO as an adjuvant to general anaesthesia on postoperative patient outcomes.
METHODS
We searched Medline, EMBASE, and Cochrane Central for works published from inception to July 6, 2023. RCTs comparing general anaesthesia with or without NO were included. Risk ratios (RRs) and standardised mean differences (SMDs) were calculated, along with 95% confidence intervals (CIs), using a random-effects model. Outcomes were derived from the Standardised Endpoints for Perioperative Medicine (StEP) outcome set. Primary outcomes were mortality and organ-related morbidity, and secondary outcomes were anaesthetic and surgical morbidity.
RESULTS
Of 3305 records, 179 full-text articles were assessed, and 71 RCTs, totalling 22 147 patients, were included in the meta-analysis. Addition of NO to general anaesthesia did not influence postoperative mortality or most morbidity outcomes. NO increased the incidence of atelectasis (RR 1.62, 95% CI 1.24 to 2.12) and postoperative nausea and vomiting (RR 1.27, 95% CI 1.15 to 1.40), and decreased intraoperative opioid consumption (SMD -0.19, 95% CI -0.35 to -0.04) and time to extubation (MD -2.17 min, 95% CI -3.32 to -1.03 min).
CONCLUSIONS
NO did not influence postoperative mortality or most morbidity outcomes. Considering the environmental effects of NO, these findings confirm that current policy recommendations to limit its use do not affect patient safety.

The diagnostic criteria for silent sinus syndrome (SSS) are still controversial, especially for the post-traumatic/surgery cases that are, nowadays, excluded from the diagnosis of SSS because lacking of spontaneously. We present a systematic review of the last 10 years and our case series of SSS associated to previous trauma/surgery, proposing a new interpretation of SSS. In this work, following the PRISMA guide lines for systematic reviews, we collected 86 articles published on PubMed, Cochrane Library and Medline Plus since 2013 to 2023 about SSS. We divided them in six groups forming the structure of the review: (1) epidemiology, (2) clinical presentation, (3) imaging, (4) etiopathogenesis, (5) sss and craniofacial trauma and (6) treatment. We reported two explicative clinical cases: two men of 34 and 37 years old, involved in motorcycle accident in 2020 and 2014, respectively, and underwent surgery. They came back in 2023 referring diplopia documented by Hess-Lancaster test. CT-scan reported two clear cases of SSS. Basing on what is reported in literature, and basing on our experience, the post-traumatic/surgery SSS are more frequent than the idiopathic ones. Our proposal is to considered them as two individual entities. We propose to adopt the name of Post-traumatic sinus syndrome, or CDR syndrome (Catalfamo-De Rinaldis), for all cases that respect four specific diagnostic criteria reported into the text.

BACKGROUND
While cutaneous melanomas are well-documented, primary melanoma of the lung (PMML), particularly with endobronchial origin, remains rare and poorly characterized. This case report addresses gaps in understanding by presenting a comprehensive case of a 71-year-old male with primary endobronchial melanoma and conducting a systematic review of PMML cases.
CASE PRESENTATION
The patient, a former smoker, presented with dyspnea, cough, and hemoptysis. Imaging revealed left lung atelectasis and a suspicious nodule. Bronchoscopy identified an endobronchial mass, subsequently treated with argon plasma coagulation and resection. Biopsy confirmed melanoma. Extensive examinations ruled out a primary skin lesion. Despite initial treatment, recurrence led to pneumonectomy. Histopathology confirmed melanoma. The patient received treatment with pembrolizumab and ipilimumab, but with poor clinical benefit.
CONCLUSIONS
Primary endobronchial melanoma is a rare entity, comprising 0.01% of lung tumors. This case underscores diagnostic challenges and emphasizes histological criteria to distinguish primary from metastatic lesions. The pathogenesis remains unclear, with theories proposing foetal melanocyte migration or squamous metaplasia. Prognosis varies, necessitating radical surgical extirpation. A systematic review revealed diverse outcomes, supporting the need for further research. In conclusion, endobronchial melanoma involves an endoscopic and surgical management, but evolving therapies, such as immunotherapy, may reshape treatment paradigms. This case contributes to our understanding of PMML, guiding future research and clinical management. As therapeutic options evolve, continued research is crucial to refine our understanding and improve outcomes for this rare malignancy.

Surgery is the primary treatment for pulmonary hydatid cysts. This systematic review and meta-analysis aimed to compare the results of capitonnage and uncapitonnage techniques for the surgery of pulmonary hydatid cysts. Descriptive Boolean queries were used to search PubMed, Scopus, and Web of Science for articles published up to June 2022 to evaluate the outcomes of pulmonary hydatid cysts in terms of mortality, postoperative complications, and hospital stay. A total of 12 studies were included. An analysis of the total side effects revealed that there was a statistically significant difference between the capitonnage and uncapitonnage groups (odds ratio=3.81, 95% confidence interval=[1.75-8.31], P < .001). The results showed that more side effects were observed in the uncapitonnage group than in the capitonnage group. The risk of side effects in the uncapitonnage group is 3.81 times higher than in the capitonnage group. The results showed that more prolonged air leak was seen in uncapitonnage group than in the capitonnage group (odds ratio=4.18, 95% confidence interval=[1.64-10.64], P=.003). The results show that more empyema was observed in uncapitonnage group than in the capitonnage group (odds ratio=4.76, 95% confidence interval=[1.29-17.57], P =0.020). An analysis of atelectasis and mean hospital stay revealed that there was no statistically significant difference between the capitonnage and uncapitonnage groups. The results reveal the advantages of capitonnage in the treatment of pulmonary hydatid cysts and that the capitonnage method is quite effective in reducing complications compared to the uncapitonnage method.

BACKGROUND
There is no consensus on the effectiveness of surgical stabilization in multiple rib fractures in Asia, especially among patients with a non-flail rib fracture pattern. We aim to synthesize the evidence on the effectiveness of surgical stabilization of rib fractures (SSRF) in an Asian population with multiple non-flail rib fractures.
METHODS
The MEDLINE, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), and Cochrane Database of Systematic Reviews were searched in this systematic literature review and meta-analysis to identify studies conducted in Asia that included patients with multiple non-flail rib fractures in at least one of their treatment groups. The intervention of interest was SSRF, and the comparator was a nonoperative treatment. The duration of mechanical ventilation (DMV) was the primary outcome. Posttreatment pain score, pneumonia, atelectasis, intensive care unit length of stay (ICU LOS), hospital length of stay (HLOS), need for tracheostomy, respiratory function, functional outcomes, quality of life (QoL), and mortality were identified as the secondary outcomes. A random effects model (REM) was used to pool data for outcomes reported in two or more studies.
RESULTS
A total of 12 studies (n=2,440 patients) were included. There was a significantly shorter DMV {mean difference (MD): -5.23 [95% confidence interval (CI): -9.64 to -0.81], P=0.02}, lower 4-week post-treatment pain score [standard mean difference (SMD): -2.24 (95% CI: -3.18 to -1.31), P<0.00001], lower risk for pneumonia [risk ratio (RR): 0.46 (95% CI: 0.23 to 0.95), P=0.04], lower risk for atelectasis [RR: 0.44, (95% CI: 0.29 to 0.65), P<0.0001], shorter ICU LOS [MD: -4.00 (95% CI: -6.33 to -1.66), P=0.0008], and shorter HLOS [MD: -6.54 (95% CI: -9.28 to -3.79), P<0.00001] in favor of SSRF. Effect estimates for the need for tracheostomy [RR: 0.67 (95% CI: 0.42 to 1.08), P=0.10] and mortality [RR: 0.94 (95% CI: 0.37 to 2.41), P=0.90] were nonsignificant.
CONCLUSIONS
In the Asian population with mainly non-flail rib fracture patterns, SSRF was associated with shorter DMV, ICU LOS, and HLOS as well as lower risks for atelectasis and pneumonia, and pain scores after 4 weeks. The risk of mortality was comparable between treatment groups.
