摘要
BACKGROUND Postoperative pulmonary complications(PPCs)are common in patients who undergo colorectal surgery.Studies have focused on how to accurately diagnose and reduce the incidence of PPCs.Lung ultrasound has been proven to be useful in preoperative monitoring and postoperative care after cardiopulmonary surgery.However,lung ultrasound has not been studied in abdominal surgeries and has not been used with wearable devices to evaluate the influence of postoperative ambulation on the incidence of PPCs.AIM To investigate the relationship between lung ultrasound scores,PPCs,and postoperative physical activity levels in patients who underwent colorectal surgery.METHODS In this prospective observational study conducted from November 1,2019 to August 1,2020,patients who underwent colorectal surgery underwent daily bedside ultrasonography from the day before surgery to postoperative day(POD)5.Lung ultrasound scores and PPCs were recorded and analyzed to investigate their relationship.Pedometer bracelets measured the daily movement distance for 5 days post-surgery,and the correlation between postoperative activity levels and lung ultrasound scores was examined.RESULTS Thirteen cases of PPCs was observed in the cohort of 101 patients.The mean(standard deviation)peak lung ultrasound score was 5.32(2.52).Patients with a lung ultrasound score of≥6 constituted the high-risk group.High-risk lung ultrasound scores were associated with an increased incidence of PPCs after colorectal surgery(logistic regression coefficient,1.715;odds ratio,5.556).Postoperative movement distance was negatively associated with the lung ultrasound scores[Spearman’s rank correlation coefficient(r),-0.356,P<0.05].CONCLUSION Lung ultrasound effectively evaluates pulmonary condition post-colorectal surgery.Early ambulation and respiratory exercises in the initial two PODs will reduce PPCs and optimize postoperative care in patients undergoing colorectal surgery.
