Abstract: Objective To investigate the risk factors of respiratory complications after right hemicolectomy,and to explore the prevention measures.
Methods A total of 336 patients who underwent right hemicolectomy from June 2012 to may 2020 were selected as the study subjects.According to the occurrence of postoperative respiratory complications,they were divided into respiratory complications group(25 cases) and no respiratory complications group(311 cases).The gender,age,body mass index,long-term smoking history,respiratory diseases,diabetes,American Society of Anesthesiologists scores,preoperative albumin,preoperative hemoglobin,disease nature,lesion location,operation type,operation method,compliance with the principle of complete mesocolic excision,operation time,and bleeding during the operation were analyzed by univariate analysis and multivariate logistic regression.
Results Univariate analysis showed that age ≥65 years,respiratory diseases,emergency surgery and operation time >3 hours related to respiratory complications after right hemicolectomy(P＜0.05).Multivariate analysis showed that age ≥65 years and respiratory diseases were independent risk factors of respiratory complications after right hemicolectomy(P＜0.05).
Conclusion The elderly and respiratory diseases will increase the risk of respiratory complications after right hemicolectomy.High risk population should be screened before right hemicolectomy.Reasonable preventive measures should be taken for the patients who were old and had respiratory diseases to reduce the incidence of postoperative respiratory complications.
