Risk factors of postoperative pulmonary infections in liver cancer patients

OBJECTIVE To analyze the risk factors of postoperative pulmonary infections in the liver cancer patients and to explore the measures of prevention and control of such infections. METHODS A total of 210 cases of patients with hepatocellular carcinoma,who underwent the surgical treatment,were selected as the observation objects,the related indexes were compared on the basis of the status of concurrent pulmonary infections,and the related risk factors of the postoperative pulmonary infections in the liver cancer patients were explored. RESULTS In the concurrent lung infection group,the percentage of the smoking patients was 42.55%,the percentage of patients with chronic respiratory disease history was 53.19%,the percentage of preoperative hypoalbuminemia patients was 23.40%,the percentage of patients who underwent preoperative deep vein puncture was 36.17%,which were higher than that of the concurrent lung infection group,the difference was statistically significant(P0.05);the percentage of patients with postoperative analgesia pump in the concurrent lung infection group was 21.28%,lower than that of the non-concurrent lung infection group,the difference was statistically significant(P0.05);the preoperative hospitalization duration of the concurrent lung infection group was(7.2±1.4)d,the operation duration(186.4±32.5)min,the intraoperative endotracheal intubation duration(162.1±17.8)min,the intraoperative bleeding amount(1264.8±150.7)ml,the duration of postoperative indwelling nasogastric intubation(12.5±4.5)d,and the duration of postoperative use of ventilator(4.5±2.4)d,all of which were significantly greater than those of the non-concurrent pulmonary infection group,the difference was statistically significant(P0.05).CONCLUSION The smoking history,chronic lung disease history,preoperative hypoalbuminemia,long duration of preoperative hospitalization,preoperative deep vein puncture,long operation duration,long duration of intraoperative endotracheal intubation,the large amount of intraoperative bleeding,not using the analgesia pump after surgery,the long duration of indwelling nasogastric tube,and use of ventilator are all the risk factors associated with the postoperative pulmonary infections in the liver cancer patients.
