Cardiopulmonary Outcomes After the Nuss Procedure in Pectus Excavatum.

ABSTRACT: Background Pectus excavatum is the most common chest wall deformity. There is still controversy about cardiopulmonary limitations of this disease and benefits of surgical repair. This study evaluates the impact of pectus excavatum on the cardiopulmonary function of adult patients before and after a modified minimally invasive repair. Methods and Results In this retrospective cohort study, an electronic database was used to identify consecutive adult (aged ≥18 years) patients who underwent cardiopulmonary exercise testing before and after primary pectus excavatum repair at Mayo Clinic Arizona from 2011 to 2020. In total, 392 patients underwent preoperative cardiopulmonary exercise testing; abnormal oxygen consumption results were present in 68% of patients. Among them, 130 patients (68% men, mean age, 32.4±10.0 years) had post-repair evaluations. Post-repair tests were performed immediately before bar removal with a mean time between repair and post-repair testing of 3.4±0.7 years (range, 2.5-7.0). A significant improvement in cardiopulmonary outcomes (P<0.001 for all the comparisons) was seen in the post-repair evaluations, including an increase in maximum, and predicted rate of oxygen consumption, oxygen pulse, oxygen consumption at anaerobic threshold, and maximal ventilation. In a subanalysis of 39 patients who also underwent intraoperative transesophageal echocardiography at repair and at bar removal, a significant increase in right ventricle stroke volume was found (P<0.001). Conclusions Consistent improvements in cardiopulmonary function were seen for pectus excavatum adult patients undergoing surgery. These results strongly support the existence of adverse cardiopulmonary consequences from this disease as well as the benefits of surgical repair.

Project description:BackgroundThoracoscopic-assisted Nuss repair is a commonly used method for treating pectus excavatum, which has always been performed under tracheal intubation and general anesthesia. However, general anesthesia with endotracheal intubation can produce intubation and anesthetic drug related complications. In non-intubation anesthesia, laryngeal mask is used instead of tracheal intubation without muscle relaxants and small doses of sedative and analgesic drugs. Therefore, non-intubation anesthesia can reduce complications and speed up postoperative recovery. This study retrospectively analyzed the clinical impact of these two anesthesia methods on thoracoscopic-assisted Nuss repair for the treatment of pectus excavatum.MethodsA total of 115 pectus excavatum patients who underwent thoracoscopic-assisted Nuss procedure repair in the Department of Thoracic Surgery of Yunnan First People's Hospital from January 2017 to January 2022 were included. All subjects in this study underwent thoracoscopic assisted Nuss repair in the same thoracic surgical team. According to different anesthesia methods, they were divided into non-intubation anesthesia group (n=62) and intubation anesthesia group (n=53). The intubation time, intraoperative mean heart rate, postoperative complications, postoperative first oral food intake, water intake, ambulation, defecation time, postoperative blood drawing results, postoperative hospital stay and total hospitalization cost were compared between the two groups.ResultsThere were no significant differences in clinical characteristics and preoperative examination indexes between the two groups, which were comparable. Compared with the intubation anesthesia group, the non-intubation anesthesia group had less anesthesia intubation time, lower intraoperative mean heart rate, less postoperative complications, such as pneumothorax, pleural effusion, and lung infection. In the non-intubation anesthesia group, the first time to eat, drink, get out of bed, and defecate were all earlier. Routine blood results 24 h after surgery indicated that the non-intubation anesthesia group had lower white blood cell, neutrophil and lymphocyte, an earlier postoperative discharge time, and lower total hospitalization expenses.ConclusionsNon-intubation anesthesia in thoracoscopic-assisted Nuss procedure for the repair of pectus excavatum can make the postoperative recovery of patients faster and has better safety and efficacy.
