Abstract

Objective

Pneumonia is a common complication and a significant cause of mortality following cardiovascular surgery. This study aimed to investigate the incidence and risk factors for pneumonia after thoracic aortic surgery.

Methods

A retrospective review was conducted on the medical records of 380 patients who underwent thoracic aortic surgery between January 2016 and December 2019. Patients were classified into pneumonia and non-pneumonia groups based on postoperative outcomes. Pneumonia was further categorized as aspiration pneumonia, ventilation-associated pneumonia (VAP), or other types. Risk factors were identified through univariate and multivariate analyses.

Results

Postoperative pneumonia during hospitalization occurred in 30 patients (7.9 %), including 18 cases of aspiration pneumonia (4.7 %) and 9 cases of VAP (2.4 %). Risk factors identified included hoarseness before surgery, aortic arch replacement, longer anesthesia time, longer intubation duration, necessity for tracheostomy, cerebrovascular disease after surgery, and postoperative recurrent laryngeal nerve paralysis. Multivariate analysis suggested that hoarseness before surgery and the necessity for tracheostomy were independent risk factors for pneumonia during hospitalization.

Conclusion

This study identified key risk factors for postoperative pneumonia after thoracic aortic surgery. These findings may aid in identifying high-risk patients and implementing preventive strategies to reduce postoperative pneumonia.

期刊介绍： The international journal Auris Nasus Larynx provides the opportunity for rapid, carefully reviewed publications concerning the fundamental and clinical aspects of otorhinolaryngology and related fields. This includes otology, neurotology, bronchoesophagology, laryngology, rhinology, allergology, head and neck medicine and oncologic surgery, maxillofacial and plastic surgery, audiology, speech science. Original papers, short communications and original case reports can be submitted. Reviews on recent developments are invited regularly and Letters to the Editor commenting on papers or any aspect of Auris Nasus Larynx are welcomed. Founded in 1973 and previously published by the Society for Promotion of International Otorhinolaryngology, the journal is now the official English-language journal of the Oto-Rhino-Laryngological Society of Japan, Inc. The aim of its new international Editorial Board is to make Auris Nasus Larynx an international forum for high quality research and clinical sciences.
