Objective
To evaluate the effect of perioperative fluid management on postoperative pulmonary complications (PPCs) of esophagectomy, and to find out the optimal scheme for perioperative fluid administration.
Methods
This retrospective cohort study enrolled 75 patients with esophageal squamous cell cancer who have received esophagectomy in West China Hospital from June to December 2014. We used the Kroenke's postoperative pulmonary complications classification system to define the PPCs. Patients with PPCs of grade Ⅱ-Ⅳ were considered as PPCs group (n=13, 12 males, 1 female, age of 64.62±8.64 years), and others were considered as non-complication group (n=62, 50 males, 12 females, age of 60.55±8.73 years). Intraoperative and postoperative fluid inputs and outputs as well as clinical characteristics between groups were compared.
Results
Between two groups, there was a great difference in postoperative albumin infusion, intraoperative fluid administration [net input, total input, net input/kg, total input/kg, net input/(kg·h) and total input/(kg·h)] and fluid input on the first postoerative 1–3 days (total input and total input/kg). The cutoff value for total input/(kg·h) in operation and total input on the first 1–3 postoerative days was 12.07 ml/(kg·h) and 178.57 ml/kg, respectively.
Conclusion
The speed of fluid infusion in operation and total input on postoperative 1-3 days are most important influence factors of PPCs. The speed in operation should not exceed 12.07 ml/(kg·h) and the total input on postoperative 1-3 days should not exceed 178.57 ml/kg. Within this range, an appropriate increase in fluid volume can make patients feel better.
Objective To investigate the relationship between preoperative mean daily step counts and pulmonary complications after thoracoscopic lobectomy in elderly patients. Methods From 2018 to 2021, the elderly patients with pulmonary complications after thoracoscopic lobectomy were included. A 1∶1 propensity score matching was performed with patients without pulmonary complications. The clinical data were compared between the two groups. ResultsTotally, 100 elderly patients with pulmonary complications were enrolled, including 78 males and 22 females, aged 66.4±4.5 years. And 100 patients without pulmonary complications were matched, including 71 males and 29 females aged 66.2±5.0 years. There was no significant difference in the preoperative data between the two groups (P>0.05). Compared to the patients with pulmonary complications, the ICU stay was shorter (8.1±4.4 h vs. 12.9±7.5 h, P＜0.001), the first out-of-bed activity time was earlier (8.8±4.5 h vs. 11.2±6.1 h, P=0.002), and the tube incubation time was shorter (19.3±9.2 h vs. 22.5±9.4 h, P=0.015) in the patients wihout pulmonary complications. There was no statistical difference in other perioperative data between the two groups (P>0.05). The mean daily step counts in the pulmonary complications group were significantly less than that in the non-pulmonary complications group (4 745.5±2 190.9 steps vs. 6 821.1±2 542.0 steps, P＜0.001). The daily step counts showed an upward trend for three consecutive days in the two groups, but the difference was not significant. Conclusion The decline of preoperative mean daily step counts is related to pulmonary complications after thoracoscopic lobectomy in elderly patients. Recording daily step counts can promote preoperative active exercise training for hospitalized patients.
ObjectiveTo evaluate the correlation between positive end-expiratory pressure (PEEP) level and postoperative pulmonary complications (PPCs) in patients undergoing thoracoscopic lung surgery. MethodsThe clinical data of patients who underwent elective thoracoscopic lung surgery at West China Hospital of Sichuan University from January 2022 to June 2023 were retrospectively analyzed. Patients were divided into 2 groups according to intraoperative PEEP levels: a PEEP 5 cm H2O group and a PEEP 10 cm H2O group. The incidence of PPCs in the two groups after matching was compared using a nearest neighbor matching method with a ratio of 1∶1, setting the clamp value as 0.02. ResultsA total of 538 patients were screened, and after propensity score-matching, a total of 229 pairs (458 patients) were matched, with an average age of 53.9 years and 69.4% (318/458) females. A total of 118 (25.8%) patients had PPCs during hospitalization after surgery, including 60 (26.2%) patients in the PEEP 5 cm H2O group and 58 (25.3%) patients in the PEEP 10 cm H2O group, with no statistically significant difference between the two groups [OR=0.997, 95%CI (0.495, 1.926), P=0.915]. Multivariate logistic regression analysis showed that PEEP was not an independent risk factor for PPCs [OR=0.920, 95%CI (0.587, 1.441), P=0.715]. ConclusionFor patients undergoing thoracoscopic lung surgery, intraoperative PEEP (5 cm H2O or 10 cm H2O) is not associated with the risk of PPCs during hospitalization after surgery, which needs to be further verified by prospective, large-sample randomized controlled studies.
ObjectiveTo investigate the correlation between the postoperative day 1 (POD1) drainage volume and postoperative pulmonary complications (PPCs). MethodsThe clinical data of 254 non-small cell lung cancer (NSCLC) patients undergoing thoracoscopic lobectomy at our department from January 2014 to June 2018 were retrospectively reviewed. According to whether there were PPCs after operation, patients were divided into a PPCs group (51 patients, 33 males and 18 females, aged 65.2±7.3 years) and a non-PPCs group (203 patients, 110 males and 93 females, aged 62.4±8.2 years). The correlation between POD1 drainage volume and PPCs was analyzed. ResultsThe POD1 drainage volume in the PPCs group was significantly more than that in the non-PPCs group (337.5±127.4 ml vs. 208.7±122.9 ml, P=0.000). The result of regression analysis showed that POD1 drainage volume was an independent risk factor for the occurrence of PPCs. Receiver operating characteristic curve (ROC curve) analysis showed that POD1 drainage volume of 265 ml was the cut-off point to predict PPCs. The rate of PPCs in the group of POD1 drainage volume less than 265 ml was significantly lower than that in the group of drainage volume more than 265 ml (8.3% vs. 43.0%, P=0.000). ConclusionThe POD1 drainage volume is closely related to the occurrence of PPCs, which can be used to predict the occurrence of PPCs.
ObjectiveTo analyze the occurrence of postoperative pulmonary complications (PPC) and the risk factors in patients with spontaneous pneumothorax who underwent micro single-port video-assisted thoracoscopic surgery (VATS).MethodsA total of 158 patients with spontaneous pneumothorax who underwent micro single-port VATS in our hospital from April 2017 to December 2019 were retrospectively included, including 99 males and 59 females, with an average age of 40.53±9.97 years. The patients were divided into a PPC group (n=21) and a non-PPC group (n=137) according to whether PPC occurred after the operation, and the risk factors for the occurrence of PPC were analyzed.ResultsAll 158 patients successfully completed the micro single-port VATS, and there was no intraoperative death. The postoperative chest tightness, chest pain, and dyspnea symptoms basically disappeared. During the postoperative period, there were 3 patients of pulmonary infection, 7 patients of atelectasis, 4 patients of pulmonary leak, 6 patients of pleural effusion, 1 patient of atelectasis and pleural effusion, and the incidence of PPC was 13.29% (21/158). Multivariate logistic regression analysis showed that lung disease [OR=32.404, 95%CI (2.717, 386.452), P=0.006], preoperative albumin level≤35 g/L [OR=14.912, 95%CI (1.719, 129.353), P=0.014], severe pleural adhesions [OR=26.023, 95%CI (3.294, 205.557), P=0.002], pain grade Ⅱ-Ⅲ 24 hours after the surgery [OR=64.024, 95%CI (3.606, 1 136.677), P=0.005] , age [OR=1.195, 95%CI (1.065, 1.342), P=0.002], intraoperative blood loss [OR=1.087, 95%CI (1.018, 1.162), P=0.013] were the risk factors for PPC after micro single-port VATS.ConclusionThere is a close relationship between PPC after micro single-port VATS and perioperative indexes in patients with spontaneous pneumothorax. Clinically, targeted prevention and treatment can be implemented according to the age, pulmonary disease, preoperative albumin level, intraoperative blood loss, degree of pleural adhesion and pain grading 24 hours after surgery.
ObjectiveTo evaluate the association of anesthesia regime (volatile or intravenous anesthetics) with the occurrence of postoperative pulmonary complications (PPCs) in adult patients undergoing elective cardiac surgery under cardiopulmonary bypass (CPB).MethodsThe electronic medical records of 194 patients undergoing elective cardiac surgery under CPB at West China Hospital, Sichuan University between September 2018 and February 2019 were reviewed, including 92 males and 102 females with an average age of 53 years. The patients were classified into a volatile group (n=94) or a total intravenous anesthesia (TIVA) group (n=100) according to anesthesia regimen during surgery (including CPB). The primary outcome was the incidence of PPCs within first 7 d after surgery. Secondary outcomes included incidence of reintubation, duration of mechanical ventilation, ICU stay and hospital stay.ResultsThere was no significant difference in the incidence of PPCs between the two groups (RR=1.020, 95%CI 0.763-1.363, P=0.896), with an incidence of 48.9% in the volatile group and 48.0% in the TIVA group. Secondary outcomes were also found no significant difference between the two groups (P>0.05).ConclusionNo association of anesthesia regimen with the incidence of PPCs is found in adult patients undergoing elective cardiac surgery under CPB.
ObjectiveTo investigate the morbidity of postoperative pulmonary complications (PPCs) in patients after transcatheter tricuspid valve replacement (TTVR). MethodsA prospective cohort study enrolled 19 patients who were diagnosed with severe or greater tricuspid regurgitation in West China Hospital from October 11, 2020 to March 1, 2021, and would receive TTVR using LuX-valve for valve replacement. The patients were divided into a PPCs group and a non-PPCs group according to the presence of PPCs. The incidence of PPCs after tricuspid valve intervention between the two groups was compared. ResultsOf 19 patients diagnosed with severe or greater tricuspid regurgitation registered in the database, 17 met the inclusion criteria, including 15 females and 2 males, with a mean age of 68.4±8.0 years. PPCs occurred in 9 of 17 (52.9%) patients. At discharge, compared with the non-PPCs group, the PPCs group had a longer postoperative hospital stay [11.0 (10.0, 17.0) d vs. 7.5 (7.0, 8.0) d, P=0.01], longer ICU stay [72.0 (45.5, 95.0) h vs. 20.5 (16.0, 22.8) h, P<0.01], and more hospital cost [74.3 (65.9, 98.3) thousand yuan vs. 52.6 (44.2, 57.4) thousand yuan, P<0.01]. At 30 days of follow-up, the PPCs group was found that the rate of New York Heart Association cardiac function≥class Ⅲ (66.7% vs. 12.5%, P<0.01) was higher, the six-minute walk distance (170.2±169.3 m vs. 377.9±80.5 m, P<0.01) was shorter and Kansas City Cardiomyopathy Questionnaire heart failure score (40.9±31.2 vs. 80.4±5.8, P<0.01) was less than those of the non-PPCs group. ConclusionPPCs are common in the patients undergoing TTVR and severely affect patients' cardiac function, exercise function and quality-of-life recovery. Proactive preoperative intervention as well as early postoperative rehabilitation management should be provided to those at high risk of PPCs.
The concept of enhanced recovery after surgery (ERAS) is composed of multidisciplinary, multimodal, and evidence-based approaches, providing a safe and cost-effective method for perioperative management to improve patient prognosis without increasing the incidence of complications. At present, ERAS for cardiac surgery has developed slowly. This article provides a review of the application and prospects of ERAS concept in the perioperative period of cardiac surgery. The measures for applying ERAS concept to the perioperative period of cardiac surgery are divided into three parts: preoperative, intraoperative, and postoperative. The aim is to provide information for the perioperative management of cardiac surgery patients and assist in their rapid recovery during the perioperative period.
[Abstract]Elderly patients with lung cancer have a significantly increased risk of perioperative cardiopulmonary complications due to physiological decline, high incidence of complications and reduced surgical tolerance, which directly affects postoperative recovery and long-term survival. Although the concepts of minimally invasive surgery and enhanced recovery after surgery have improved clinical outcomes, early recognition and intervention of postoperative complications in elderly patients remains a significant challenge in the field of thoracic surgery. By integrating recent literature and clinical practice, this paper systematically analyzes the pathophysiological mechanism and risk factors of perioperative cardiopulmonary complications in elderly patients with lung cancer, and discusses individualized intervention strategies based on risk stratification and multidisciplinary team, in order to provide theoretical basis and practical guidance for optimizing perioperative management and improving postoperative prognosis in elderly patients.
Objective To evaluate the effect of intraoperative fluid infusion volume on postoperative pulmonary complications (PPCs) in patients after minimally invasive endoscopic esophageal carcinoma resection. Methods From June 2019 to August 2021, 486 patients undergoing elective minimally invasive endoscopic esophagectomy for esophageal cancer were retrospectively screened from the electronic medical record information management system and anesthesia surgery clinical information system of West China Hospital of Sichuan University. There were 381 males and 105 females, with a median age of 64.0 years. Taking the incidence of pulmonary complications within 7 days after operation as the primary outcome, the correlation between intraoperative fluid infusion volume and the occurrence of PPCs within 7 days was clearly analyzed by regression analysis. ResultsThe incidence of pulmonary complications within 7 days after surgery was 33.5% (163/486). Regression analysis showed that intraoperative fluid infusion volume was correlated with the occurrence of PPCs [adjusted OR=1.089, 95%CI (1.012, 1.172), P=0.023], especially pulmonary infection [adjusted OR=1.093, 95%CI (1.014, 1.178), P=0.020], and pleural effusion [adjusted OR=1.147, 95%CI (1.007, 1.306), P=0.039]. Pulmonary infection was significantly less in the low intraoperative fluid infusion group [<6.49 mL/(kg·h), n=115] compared with the high intraoperative fluid infusion group [≥6.49 mL/(kg·h), n=371] (18.3% vs. 34.5%, P=0.023). Intraoperative fluid infusion volume was positively associated with death within 30 days after surgery [adjusted OR=1.442, 95%CI (1.056, 1.968), P=0.021]. Conclusion Among patients undergoing elective minimally invasive endoscopic esophageal cancer resection, intraoperative fluid infusion volume is related with the occurrence of PPCs within 7 days after the surgery, especially pulmonary infection and pleural effusion, and may affect death within 30 days after the surgery.
