Background: Among patients with congenital heart disease, particularly those with a history of undergoing the Fontan operation, pregnancy presents a significant maternal–fetal risk, especially when complicated by severe valvular dysfunction. Lung reperfusion syndrome (LRS) is a rare but life-threatening complication occurring following valve intervention. Multidisciplinary management, including by Cardio-Obstetrics teams, is essential for optimizing outcomes in such high-risk cases. Methods: We present the case of a 37-year-old pregnant patient with previously repaired tetralogy of Fallot (via the Fontan procedure) who presented at 24 weeks gestation with worsening severe pulmonary stenosis and right-ventricular dysfunction. The patient had been lost to cardiac follow-up for over a decade. She experienced recurrent arrhythmias, including supraventricular and non-sustained ventricular tachycardia, prompting hospital admission. A multidisciplinary team recommended transcatheter pulmonic valve replacement (TPVR), performed at 28 weeks’ gestation. Results: Post-TPVR, the patient developed acute hypoxia and hypotension, consistent with Lung Reperfusion Syndrome, necessitating intensive cardiopulmonary support. Despite initial stabilization, progressive maternal respiratory failure and fetal compromise led to an emergent cesarean delivery. The neonate’s neonatal intensive care unit (NICU) course was complicated by spontaneous intestinal perforation, while the mother required intensive care unit (ICU)-level care and a bronchoscopy due to new pulmonary findings. She was extubated and discharged in stable condition on postoperative day five. Conclusions: This case underscores the complexity of managing severe congenital heart disease and valve pathology during pregnancy. Lung reperfusion syndrome should be recognized as a potential complication following TPVR, particularly in pregnant patients with Fontan physiology. Early involvement of a multidisciplinary Cardio-Obstetrics team and structured peripartum planning are critical to improving both maternal and neonatal outcomes. Full article

Background: Opioid dependence is prevalent among patients undergoing lumbar spinal fusion and has been linked to poor postoperative outcomes. However, its specific impact on surgical complications and hospital resource utilization remains unclear. This study evaluates the association between opioid dependence and postoperative complications, length of stay (LOS), and hospital charges in lumbar fusion patients. Methods: A retrospective analysis was conducted using the National Inpatient Sample (NIS) database from 2016 to 2021. Adult patients (aged > 18 years) who underwent lumbar fusion surgery were identified and categorized based on opioid dependence using ICD-10 codes. Propensity score weighting (PSW) was employed to balance baseline characteristics. Primary outcomes included inpatient mortality, LOS, hospital charges, and postoperative complications. Statistical analyses were performed using survey-weighted generalized linear models. Results: Among 597,455 lumbar fusion patients, 7715 (1.3%) had documented opioid dependence. After PSW, opioid-dependent patients had significantly increased odds of blood loss anemia (OR 1.79, p < 0.001), respiratory complications (OR 2.17, p < 0.001), surgical site infections (OR 3.94, p = 0.001), and cardiac complications (OR 1.53, p = 0.002). They also had higher hospital charges (mean difference USD 17,739.2, p < 0.001) and prolonged LOS (mean difference 0.83 days, p < 0.001). Differences in urinary tract infections, acute renal failure, and stroke were not statistically significant after PSW. Conclusions: Opioid dependence is associated with increased postoperative complications, longer hospital stays, and higher healthcare costs in lumbar fusion patients. These findings highlight the need for improved perioperative pain management and opioid stewardship strategies to optimize surgical outcomes. Full article

Background/Objectives: Pediatric postoperative respiratory failure in the United States is increasingly considered a significant adverse event due to the increased risk of co-morbidities, suffering, and cost of healthcare. This study investigates associations between pediatric adverse events (PAEs) and hospital and patient characteristics within the inpatient hospital setting, focusing solely on the framework of pediatric quality indicators (PDIs) from the Agency for Healthcare Research and Quality (AHRQ). Specifically, the study focuses on PDI 09-Postoperative Respiratory Failure (PORF). Methods: This quantitative research analyzed the inpatient discharge data from the Healthcare Cost and Utilization Project (HCUP) Kids’ Inpatient Databases (KID) for 2019. We performed multivariate logistic regression to analyze patient-level encounters with PORF. Results: The results indicate that smaller, rural, and non-teaching hospitals exhibit significantly lower odds of PDI 09 than large, urban, and urban teaching hospitals, reflecting a concentration of operative procedures. In comparison, the Western United States exhibits higher odds of PDI 09. Various individual factors such as gender, age, race, service lines, payment sources, and major operating room procedures demonstrate differing levels of significance concerning PDI 09, warranting further investigation into confounding factors. In contrast, hospital ownership consistently shows lower odds of PORF risk for private, investor-owned hospitals. Conclusions: This study provides contextual expansion on the findings and offers valuable insights into PAEs in the inpatient hospital setting. It highlights areas for developing evidence-based interventions and guidelines for clinicians and policymakers. Ultimately, the findings contribute to the growing understanding of factors influencing PORF and emphasize the importance of targeted strategies for improving pediatric patient safety. Full article

Background: Colorectal surgery remains a cornerstone in the management of colorectal cancer, yet postoperative complications continue to impact surgical outcomes. This study investigates key risk factors influencing morbidity, focusing on patient comorbidities, tumor characteristics, surgical techniques, and anastomotic methods. Methods: A retrospective analysis was conducted on 195 patients who underwent colorectal cancer surgery between January 2021 and December 2024 at the Clinical Hospital of Nephrology “Carol Davila”. Variables analyzed included patient demographics, comorbidities, tumor staging, surgical approach, and postoperative complications. Statistical methods included chi-square tests and multivariate logistic regression (significance threshold: p < 0.05). Results: The overall complication rate was 21%, with anastomotic leakage observed in 8.2% of cases. Significant risk factors for morbidity included cardiovascular disease (p = 0.001), chronic respiratory failure (p = 0.003), and chronic renal failure (p = 0.002). Laparoscopic surgery had a lower complication rate (7.1%) than open surgery (28%) (p = 0.003). Mechanical anastomosis showed lower complication rates than manual suturing (p = 0.009). Left-sided resections were associated with higher morbidity than right-sided procedures (p = 0.013). Conclusions: Optimizing colorectal surgery outcomes requires personalized perioperative strategies. Laparoscopic approaches and mechanical anastomosis significantly reduce complications. Further multicenter studies are needed to confirm these findings and enhance surgical guidelines. Full article

Background: Cytoreductive surgery (CS) and hyperthermic intraperitoneal chemotherapy (HIPEC) increases survival in peritoneal carcinomatosis, but complications may affect the long-term prognosis. We aimed to evaluate the postoperative evolution after CS + HIPEC, the appearance of adverse outcomes, and the associated risk factors. Methods: This was a retrospective observational study evaluating clinical practice in patients undergoing CS + HIPEC from 2016 to 2023 in a tertiary-level university hospital. The pre-, intra-, and postoperative variables were collected. The postoperative evolution, the appearance of postoperative complications, and the mortality were analyzed according to the perioperative data. Results: In total, 62.3% of the patients developed some kind of complication. Renal failure was related to the length of surgery [mean difference (md) 111 min, 95% CI 11–210, p = 0.029], postoperative vasoactive support [Odds Ratio (OR) 3.4, 95% CI 1.1–10.6, p = 0.033], and non-invasive mechanical ventilation (OR 5.5, 95% CI 1.5–20.5, p = 0.007). Respiratory failure was associated with renal replacement therapies (OR 13.8, 95% CI 1.3–143.9, p = 0.006), postoperative creatinine (md 0.27 mg·dL⁻¹, 95% CI 0.1–0.4, p = 0.001), and C-reactive protein (md 33.5 mcg·L⁻¹, 95% CI 0.1–66.8, p = 0.049). Infectious complications were related to the length of surgery (md 84 min, 95% CI 12–156, p = 0.024), non-invasive mechanical ventilation (OR 4.4, 95% CI 1.2–16.1, p = 0.018), and renal replacement therapies (OR 11.6, 95% CI 1.1–119.6, p = 0.012). The hospital stay was longer in patients with complications (md 14.8 ± 5.5 days, 95% CI 3.8–25.8, p = 0.009). The mortality rate at 12 months was 15.6%. The mortality risk factors were the preoperative hemoglobin (md −1.7 g·dL⁻¹, 95% CI −2.8–−0.7, p = 0.001) and creatinine (md −0.12 mg·dL⁻¹, 95% CI −0.21–−0.04, p = 0.007) and the postoperative hemoglobin (md −1.15 g·dL⁻¹, 95% CI 0.01–2.30, p = 0.049) and C-reactive protein (md 54.6 mcg·L⁻¹, 95% CI 18.5–90.8, p = 0.004). Intraoperative epidural analgesia was found to be a protective factor for 12-month mortality (OR 0.25, 95% CI 0.07–0.90 p = 0.027). A multivariate analysis performed after a univariate analysis showed that the only risk factor for overall mortality was not using intraoperative epidural analgesia. Conclusions: CS + HIPEC led to a high incidence of postoperative complications, but the occurrence of complications did not seem to affect postoperative survival. Full article

Background/Objectives: Surgical procedures in chronic obstructive pulmonary disease (COPD) patients carry a high risk of postoperative respiratory failure, often causing the need for mechanical ventilation and prolonged intensive care unit (ICU) stays. Accompanying COPD with heart failure further increases the risk of complications. This study aimed to identify predictors of mortality, prolonged ICU and hospital stays, the need for mechanical ventilation, and vasoactive drug usage in ICU patients with moderate to severe COPD undergoing elective non-cardiac surgery. Methods: This retrospective cohort study analyzed eICU-CRD data, including adult patients with moderate to severe COPD admitted to the ICU from the operating room following elective non-cardiac surgery. Spearman’s correlation analysis was performed to assess associations between intraoperative ventilation parameters and ICU/hospital length of stay, postoperative laboratory parameters, and their perioperative dynamics. Results: This study included 680 patients (21% with severe COPD). Hospital and ICU mortality were 8.6% and 4.4%, respectively. Median ICU and hospital stays were 1.9 and 6.6 days, respectively. Intraoperative tidal volume, expired minute ventilation, positive end-expiratory pressure, mean airway pressure, peak inspiratory pressure, and compliance had no statistically significant association with mortality, postoperative mechanical ventilation, its duration, or the use of vasopressors/inotropes. Tidal volume correlated positively with changes in monocyte count (R = 0.611; p = 0.016), postoperative lymphocytes (R = 0.327; p = 0.017), and neutrophil count (R = 0.332; p = 0.02). Plateau pressure showed a strong positive association with the neutrophil-to-lymphocyte ratio (R = 0.708; p = 0.001). Conclusions: Intraoperative ventilation modes and parameters in COPD patients appear to have no significant impact on the outcomes or laboratory markers, except possibly for the neutrophil-to-lymphocyte ratio, although its elevation cause remains unclear.

Background/Objectives: The frozen elephant trunk (FET) technique was introduced as a possible single-stage procedure for treating aortic arch pathologies. However, up to a third of patients are reported to need subsequent completion (extension). This retrospective analysis aimed to evaluate the impact of early (within 30 days; EC group) versus late (>30 days; LC group) endovascular completion with thoracic endovascular aortic repair (TEVAR) in patients treated with FET. Methods: A single-center, retrospective analysis of all consecutive patients for the period between June 2017 and December 2023 who underwent FET and received endovascular extension was conducted. Indications for endovascular extension were aneurysms of the descending aorta, aneurysmal progress, endoleak, malperfusion, distal stent-induced new entry (dSINE), and aortic rupture. Results: A total of 37 of 232 FET patients received endovascular extension (15.9%). Average age at the time of TEVAR was 63.3 ± 10.3 years. There was an increase in the maximum total aortic diameter post-FET from 40.8 ± 9 mm to 45.1 ± 14 mm prior to TEVAR. Only 14 patients (37.8%) had the desired complete occlusion of the false lumen or aneurysm prior to extension; 23 (62.2%) still had relevant perfusion of the false lumen or aneurysm. The EC and LC groups were defined by time between FET and TEVAR: a mean of 4.8 ± 5.2 days in the EC group and 18.4 ± 18 months in the LC group. The EC group had markedly more complex procedures, reflected in intensive care (10.7 ± 6.9 vs. 0.1 ± 0.3 days, p < 0.001) and hospitalization (22.4 ± 14.0 vs. 8.1 ± 5.6 days, p = 0.003) durations. There was one early death due to multiorgan failure in the EC group and there were none in the LC group. There were no major cardiac events in either group. In the EC group, seven patients (50%) suffered from postoperative respiratory failure and four (28.6%) developed acute kidney failure requiring dialysis. Only one patient in the LC group (4.3%) experienced complications. During follow-up, another three patients (21.4%) of the EC group died, but none of the LC group did. Post-extension aortic remodeling was similar in both groups, with complete occlusion achieved in 27 cases (72%) during early follow-up and increased to 90.6% after a mean of 22.0 ± 23.4 months. Conclusions: Following aortic arch repair using FET, there is still a need for second-stage repair in 16% of patients. Endovascular completion post-FET is safe and feasible with a technical success rate of 100%, but early completion is associated with greater morbidity and mortality. TEVAR extension surgery may be better delayed, if possible, until after recovery from the hybrid arch repair. Full article

The use of high-flow nasal cannula (HFNC) as an oxygen therapy post-extubation has demonstrated varying success rates across different surgical populations. This study aimed to identify the predictive factors influencing HFNC weaning outcomes in patients with postoperative extubation hypoxemia. We conducted a retrospective analysis of patients in a surgical intensive care unit, categorized into three major postoperative groups: cardiothoracic surgery, upper abdominal surgery, and other surgeries. Our analysis examined pre-extubation weaning profiles, vital signs before and after HFNC initiation, and changes in physiological parameters during HFNC use. A total of 90 patients were included, divided into two groups based on HFNC weaning success or failure. Key parameters analyzed included maximal inspiratory pressure (MIP), PaO₂/FiO₂ (P/F) ratio, vital signs, SpO₂ levels, respiratory rate (RR), heart rate (HR), respiratory rate–oxygenation (ROX) index, and HFNC duration. The findings revealed that cardiothoracic and upper abdominal groups showed significantly higher HFNC weaning success rates (73.3% and 70.6%) compared to the other surgeries group (34.6%) (p = 0.004). Critical predictors of successful weaning included pre-HFNC SpO₂, P/F ratio, and changes in the ROX index, particularly in upper abdominal and other surgeries groups. In cardiothoracic surgery patients, higher maximal inspiratory pressure (MIP) (p = 0.031) was associated with improved outcomes, while prolonged HFNC use correlated with weaning success in this group (p = 0.047). These findings underscore the necessity of tailoring HFNC strategies to surgical characteristics and individual patient profiles. For cardiothoracic surgery patients, pre-extubation MIP, post-extubation RR, ΔROX, and ΔHR were identified as key predictive factors. In upper abdominal surgery, pre-extubation P/F ratio, post-extubation SpO₂, and ΔROX played crucial roles. For patients undergoing other types of surgeries, pre-extubation P/F ratio and ΔROX remained the most reliable predictors of HFNC weaning success. Full article

Interstitial lung diseases (ILDs) represent a heterogenous group of lung disorders marked by inflammation and/or fibrosis of the lung parenchyma, often leading to progressive shortness of breath and end-stage respiratory failure. In the U.S., ILDs affect approximately 650,000 individuals and cause approximately 25,000–30,000 deaths annually. Lung transplantation (LTx) offers definitive treatment for advanced ILD, with improved survival attributed to advancements in immunosuppression, organ preservation, surgical techniques, and postoperative care. However, disease recurrence in transplanted lungs remains a significant concern. Understanding the risk factors and mechanisms underlying recurrence is critical for refining recipient selection and improving outcomes. This review examines ILD recurrence post LTx and its implications for lung transplantation success. Full article

Background/Objectives: The etiology of lumbar spine revision surgery is multifactorial, involving mechanical, biological, and clinical factors that challenge sustained spinal stability. Comparative analysis reveals significantly higher complication rates, prolonged hospital stays, and increased costs for revision surgeries compared to primary fusions, despite low mortality rates. Leveraging a comprehensive dataset of 456,750 patients, this study identifies predictors of revision surgery and provides actionable insights to enhance patient outcomes and optimize healthcare resource allocation. Methods: A total of 456,750 patients registered in the National Inpatient Sample (NIS) database from 2016 to 2019 were identified as having undergone single-level lumbar fusion surgery (primary fusion: 99.5%; revision fusion: 0.5%). Multivariable logistic regression models adjusted for patient demographics, clinical comorbidities, and hospital characteristics were constructed to evaluate clinical outcomes and postoperative complications. Results: Patients undergoing revision lumbar fusion surgery were significantly younger compared to those undergoing primary fusion procedures (53.92 ± 20.65 vs. 61.87 ± 12.32 years, p < 0.001); among the entire cohort, 56.4% were women. Compared with patients undergoing primary lumbar fusion, those undergoing revision fusion surgery were significantly more likely to experience surgical site infections (odds ratio [OR] 27.10; 95% confidence interval [95% CI] 17.12–42.90; p < 0.001), urinary tract infections (OR 2.15; 95% CI 1.39–3.33; p < 0.001), and prolonged length of stay (OR 1.53; 95% CI 1.24–1.89; p < 0.001). Revision surgery patients had significantly lower odds of incurring high-end hospital charges (OR 0.65; 95% CI 0.51–0.83; p < 0.001). Other complications, including respiratory complications, dural tears, thromboembolic events, and acute renal failure, showed no statistically significant differences between the two groups. In-hospital mortality rates were low and did not differ significantly between groups (revision: 0.2% vs. primary: 0.1%, OR 3.29; 95% CI 0.45–23.84; p = 0.23). Conclusions: Patients undergoing revision lumbar fusion surgeries face significantly higher risks of surgical site infections, urinary tract infections, and prolonged hospital stays compared to primary fusion procedures. These findings highlight the need for targeted interventions to improve perioperative management and reduce complications in revision lumbar fusion surgery. Full article

Background: Mediastinal mass syndrome represents a major threat to respiratory and cardiovascular integrity, with difficult evidence-based risk stratification for interdisciplinary management. Methods: We conducted a narrative review concerning risk stratification and difficult airway management of patients presenting with a large mediastinal mass. This is supplemented by a case report illustrating our individual approach for a patient presenting with a subtotal tracheal stenosis due to a large cyst of the thyroid gland. Results: We identified numerous risk stratification grading systems and only a few case reports of regional anesthesia techniques for extracorporeal membrane oxygenation patients. Clinical Case: After consultation with his general physician because of exertional dyspnea and stridor, a 78-year-old patient with no history of heart failure was advised to present to a cardiology department under the suspicion of decompensated heart failure. Computed tomography imaging showed a large mediastinal mass that most likely originated from the left thyroid lobe, with subtotal obstruction of the trachea. Prior medical history included the implantation of a dual-chamber pacemaker because of a complete heart block in 2022, non-insulin-dependent diabetes mellitus type II, preterminal chronic renal failure with normal diuresis, arterial hypertension, and low-grade aortic insufficiency. After referral to our hospital, an interdisciplinary consultation including experienced cardiac anesthesiologists, thoracic surgeons, general surgeons, and cardiac surgeons decided on completing the resection via median sternotomy after awake cannulation for veno-venous extracorporeal membrane oxygenation via the right internal jugular and the femoral vein under regional anesthesia. An intermediate cervical plexus block and a suprainguinal fascia iliaca compartment block were performed, followed by anesthesia induction with bronchoscopy-guided placement of the endotracheal tube over the stenosed part of the trachea. The resection was performed with minimal blood loss. After the resection, an exit blockade of the dual chamber pacemaker prompted emergency surgical revision. The veno-venous extracorporeal membrane oxygenation was explanted after the operation in the operating room. The postoperative course was uneventful, and the patient was released home in stable condition. Conclusions: Awake veno-venous extracorporeal membrane oxygenation placed under local anesthetic infiltration with regional anesthesia techniques is a feasible individualized approach for patients with high risk of airway collapse, especially if the mediastinal mass critically alters tracheal anatomy. Compressible cysts may represent a subgroup with easy passage of an endotracheal tube. Interdisciplinary collaboration during the planning stage is essential for maximum patient safety. Prospective data regarding risk stratification for veno-venous extracorporeal membrane oxygenation cannulation and effectiveness of regional anesthesia is needed. Full article

Background: Recent publications suggest that the threshold for validation of the learning curve is 25 procedures. The aim of this study was to evaluate this threshold using another rarely used method, based on a composite quality indicator. Methods: We included all patients from the French medico-administrative database receiving robot-assisted surgery for lung cancer, with a focus on hospitals performing at least 25 procedures over the period 2019–2022. For postoperative complication analysis, we used the Clavien–Dindo classification. We used the sequential probability ratio test to estimate the number of procedures at which a hospital achieved its learning curve. Results: In France, the number of robotic-assisted procedures has risen steadily in the past few years: 195 in 2019 and 1567 in 2022 (overall, 3706 Robot-Assisted surgeries). The total number of patients with Clavien–Dindo classification > II was 833 (24.7%). Among the 28 hospitals performing at least 25 procedures, eight achieved their learning curve with thresholds ranging from 94 to 174 procedures, and the median was 110. Severe complications such as acute respiratory distress syndrome, respiratory failure, heart failure, acute ischemia of the lower limbs, or pulmonary embolism were significantly more frequent in the group of hospitals that did not validate the learning curve threshold. Conclusions: This study suggests that the threshold of 25 procedures may not be sufficient to validate the robot-assisted surgery learning curve in lung cancer surgery. To significantly reduce postoperative complications, a hospital would need to perform 94 to 174 procedures to guarantee patient safety. Full article

Cardiac surgery procedures are among the main treatments for people with cardiovascular disease, with physiotherapy playing a vital part. Respiratory complications are common and associated with prolonged Intensive Care Unit (ICU) and hospital stay, as well as increased mortality. Inspiratory muscle training has been found to be beneficial in improving respiratory muscle function in critically ill patients and patients with heart failure. The purpose of this review is to present the results of implementing inspiratory muscle training (IMT) programs in patients before and/or after cardiac surgery. The PubMed, Embase and Science Direct databases were searched from January 2012 to August 2023. In the present review, randomized controlled clinical trials (RCTs), clinical trials and quasi-experimental studies conducted in adult patients pre and/or post cardiac surgery were included. Fifteen studies were considered eligible for inclusion in the review. The results revealed that the IMT programs varied in intensity, repetitions, and duration in all included studies. Most studies implemented the IMT after the surgery. Statistical significance between groups was noted in Maximal Inspiratory Pressure and the 6-Minute Walk Distance Test. Preoperative and postoperative programs could improve inspiratory muscle strength, pulmonary function, and functional capacity as well as decrease the length of hospital stay in patients undergoing cardiac surgery. No clear evidence emerged favoring low or higher IMT intensities. The combination of IMT with other forms of exercise might be beneficial in patients undergoing cardiac surgery. However, further RCTs are required to provide confirming evidence. Full article

Objective: Massive pulmonary embolism (PE) remains a life-threatening condition, often leading to acute respiratory and cardiac failure. This study evaluates the role of extracorporeal membrane oxygenation (ECMO) as a supportive treatment for high-risk patients undergoing surgical pulmonary embolectomy or catheter-based thrombectomy. Methods: Between January 2018 and December 2023, 27 patients with high-risk massive PE were treated at our center. Surgical embolectomy (n = 7) and catheter-based thrombectomy (n = 5) were performed, with ECMO support (veno-arterial [VA] or veno-arterial-venous [VAV]) initiated preoperatively, intraoperatively, or postoperatively, based on hemodynamic instability. ECMO was used as a bridge to recovery, and outcomes were assessed in terms of mortality, hemodynamic stabilization, and recovery. Results: Of the 27 patients, 20 were supported with ECMO, with 7 requiring VA-ECMO intraoperatively due to difficulties in weaning from cardiopulmonary bypass (CPB). Nine patients were later transitioned to VAV-ECMO due to Harlequin syndrome and persistent hemodynamic instability. The in-hospital mortality rate was 18.5% (n = 5), with survivors showing significant improvements in hemodynamic and biochemical parameters post-ECMO, including reduced lactate levels, improved right ventricular function, and the stabilization of mean arterial pressure. The mean follow-up time was 10.2 ± 3.9 months, with no late deaths or complications observed. Conclusions: ECMO provides effective life support in high-risk patients with massive PE who are undergoing surgical embolectomy or thrombectomy. It stabilizes hemodynamics, improves cardiac and pulmonary function, and facilitates recovery in critically ill patients. Further research is needed to refine patient selection, optimize ECMO timing, and assess long-term outcomes to determine its definitive role in the management of high-risk PE. Full article

Background and Objectives: To assess the impact of preoperative inflammatory parameters on the necessity for intensive care unit (ICU) admission and survival after pneumonectomy. Materials and Methods: We enrolled 207 adult patients who underwent pneumonectomy between December 2016 and January 2022. We collected data from patients’ electronic medical records. Results: The preoperative albumin level was statistically lower, need for blood transfusion was higher, and length of hospital stay was longer in ICU-admitted patients (p = 0.017, p = 0.020, and p = 0.026, respectively). In multivariate analysis, intra-pericardial pneumonectomy and postoperative complications were predictive factors for ICU admission (OR = 3.46; 95%CI: 1.45–8.23; p = 0.005 and OR = 5.10; 95%CI: 2.21–11.79; p < 0.001, respectively). Sleeve or pericardial pneumonectomy (p = 0.010), intraoperative vascular injury (p = 0.003), the need for mechanical ventilation (p < 0.001), acute renal failure (p = 0.018), sepsis (p = 0.008), respiratory failure (p < 0.001), pneumonia (p = 0.025), the need for blood transfusion (p = 0.047), elevated blood urea nitrogen (BUN) (p = 0.046), and elevated creatinine levels (p = 0.004) were more common in patients who died within 28 days. Patients who died within 90 days exhibited higher preoperative neutrophil-to-lymphocyte ratio (NLR) values (p = 0.019) and serum creatinine levels (p = 0.008), had a greater prevalence of sleeve or intra-pericardial pneumonectomy (p = 0.002), the need for mechanical ventilation (p < 0.001), intraoperative vascular injury (p = 0.049), sepsis (p < 0.001), respiratory failure (p = 0.019), and contralateral pneumonia (p = 0.008) than those who did not. Conclusions: Intra-pericardial pneumonectomy and postoperative complications are independent predictors of ICU admission after pneumonectomy. Tracheal sleeve and intra-pericardial procedures, intraoperative and postoperative complications, the need for blood transfusion, preoperative NLR ratio, BUN and creatinine levels may also be potential risk factors for mortality.
