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.
ObjectiveTo investigate the correlation between lung ultrasonography and pulmonary complications after cardiac surgery.MethodsFifty-two patients after cardiac surgery in our hospital from January to May 2017 were recruited. There were 27 males and 25 females, aged 60.50±10.43 years. Lung ultrasonography was performed by specially trained observers, video data were saved, and lung ultrasound score (LUS) were recorded. The correlation between the LUS and the patients' pulmonary function was evaluated.ResultsLUS was 17.80±3.87, which was negatively correlated to the ratio of arterial PO2 to the inspired oxygen fraction (PaO2/FiO2) during examination, without significant difference (r=–0.363, P=0.095), but significantly negatively correlated to PaO2/FiO2 changes 24 hours postoperatively (r=–0.464, P=0.034).ConclusionThe changes of lung ventilation area may occur earlier than the changes of lung function. Bedside LUS is an effective method for clinical monitoring of pulmonary complications.
Objective To evaluate the association between pressure-controlled ventilation-volume guaranteed (PCV-VG) mode and volume-controlled ventilation (VCV) mode on postoperative pulmonary complications (PPCs) in patients undergoing thoracoscopic lung resection. Methods A retrospective cohort analysis of 329 patients undergoing elective thoracoscopic lung resection in West China Hospital of Sichuan University between September 2020 and March 2021 was conducted, including 213 females and 116 males, aged 53.6±11.3 years. American Society of Anesthesiologists (ASA) grade wasⅠ-Ⅲ. The patients who received lung-protective ventilation strategy during anesthesia were divided into a PCV-VG group (n=165) and a VCV group (n=164) according to intraoperative ventilation mode. Primary outcome was the incidence of PPCs during hospitalization. Results A total of 73 (22.2%) patients developed PPCs during hospitalization. The PPCs incidence of PCV-VG and VCV was 21.8% and 22.6%, respectively (RR=0.985, 95%CI 0.569-1.611, P=0.871). Multivariate logistic regression analysis showed that there was no statistical difference in the incidence of PPCs between PCV-VG and VCV mode during hospitalization (OR=0.846, 95%CI 0.487-1.470, P=0.553). Conclusion Among patients undergoing thoracoscopic lung resection, intraoperative ventilation mode (PCV-VG or VCV) is not associated with the risk of PPCs during hospitalization.
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.
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 evaluate the effect of perioperative nebulization of ipratropium bromide on preoperative pulmonary function and incidence of postoperative pulmonary complications as well as safety in chronic obstructive pulmonary disease (COPD) patients who underwent lung resection in thoracic surgery. MethodsDuring November 18, 2013 to August 12, 2015, 192 COPD patients with a necessity of selective surgical procedures of lobectomy or right bilobectomy or segmentectomy under general anaesthesia in 10 centers were 1 : 1 randomized to an ipratropium bromide group (96 patients) and a placebo group (96 patients), to compare the effect on preoperative pulmonary function and incidence of postoperative pulmonary complications. The average age of treated patients was 62.90±6.50 years, with 168 male patients and 22 female patients. Results The demographic and baseline characteristics were well-balanced between the two groups. The adjusted mean increase of forced expiratory volume in one second (FEV1) in the ipratropium bromide group was significantly higher than that in the placebo group (169.90±29.07 mL vs. 15.00±29.35 mL, P<0.05). The perioperative use of ipratropium bromide significantly decreased incidence of postoperative pneumonia (2.6% vs. 14.1%, P<0.05). There was no ipratropium bromide related adverse event (AE) observed in this trial. ConclusionThis trial indicates that perioperative nebulization of ipratropium bromide significantly improves preoperative lung function and reduces postoperative pneumonia in COPD patients undergoing lung resection in thoracic surgery, and has good safety profile.
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.
Tricuspid valve, also known as "forgotten valve" because of the high natural and surgical mortality. Transcatheter tricuspid valve replacement is an innovative surgical method to treat tricuspid regurgitation, which improves the prognosis of patients and is gradually being popularized in clinics. However, postoperative pulmonary complications are still the main causes affecting the rapid recovery and death. More and more medical experts begin to use preoperative inspiratory muscle training to reduce postoperative pulmonary complications and improve the quality of life of patients after cardiac surgery. However, there was no report on the effect of preoperative inspiratory muscle training on pulmonary complications after transcatheter tricuspid valve replacement. Therefore, for the first time, we boldly speculate that inspiratory muscle training can reduce pulmonary complications after transcatheter tricuspid valve replacement, and put forward suggestions for its treatment mechanism and strategy. But this rehabilitation intervention lacks practical clinical research. Unknown challenges may also be encountered, which may be a new research direction.
Objective
To research the relationship between decrease of serum surfactant protein D (SP-D) level reduced by pulmonary rehabilitation training and postoperative pulmonary complications (PPC).
Methods
From May 2015 through December 2015, 80 consecutive non-small cell lung cancer (NSCLC) patients with surgical treatment in West China Hospital, who were at least with a high risk factor, were randomly divided into two groups including a group R and a group C. There were 36 patients with 25 males and 11 females at age of 63.98±8.32 years in the group R and 44 patients with 32 males and 12 females at age of 64.58±6.71 years in the group C.The group R underwent an intensive preoperative pulmonary rehabilitation (PR) training for one week, and then with lobectomy. The group C underwent only lobectomy with conventional perioperative managements. Postoperative pulmonary complications, average days in hospital, other clinic data and the serum SP-D level in a series of time from the date of admission to discharge (5 time points) were analyzed.
Results
The incidence of PPC in the group R was 5.56%(2/36),which was lower than that in the group C (P=0.032). The descender of the serum SP-D level of the patients in the group R (30.75±5.57 ng/mlvs. 24.22±3.08 ng/ml) was more obvious than that in the group C (31.16±7.81 ng/mlvs. 30.29±5.80 ng/ml,P=0.012). The descender of the serum SP-D level of the patients with PPC was more obvious than that of patients without PPC (P=0.012).
Conclusion
The preoperative PR training could reduce the PPC of lung cancer surgery with high risk factors. The serum SP-D level could reflect the effect of preoperative pulmonary rehabilitation training.
In the past two decades, adult cardiac surgery has developed by leaps and bounds in both anesthetic techniques and surgical methods, whereas the incidence of postoperative pulmonary complications (PPCs) has not changed. Until now PPCs are still the most common complications after cardiac surgery, resulting in poor prognosis, significantly prolonged hospital stays and increased medical costs. With the promotion of the concept of enhanced recovery after surgery (ERAS), pre-rehabilitation has been becoming a basic therapy to prevent postoperative complications. Among them, preoperative inspiratory muscle training as a very potential intervention method has been widely and deeply studied. However, there is still no consensus about the definition and diagnostic criteria of PPCs around the world; and there is significant heterogeneity in preoperative inspiratory muscle training in the prevention of pulmonary complications after cardiac surgery in adults, which impedes its clinical application. This paper reviewed the definition, mechanism, and evaluation tools of PPCs, as well as the role, implementation plan and challenges of preoperative inspiratory muscle training in the prevention of PPCs in patients undergoing cardiac surgery, to provide reference for clinical application.
