Time of postoperative strict bed rest among patients with CT-guided percutaneous lung biopsy

Abstract

Objective To explore the safety and feasibility of time of postoperative strict bed rest shorten to one hour among patients with CT-guided percutaneous lung biopsy. Methods From July 2016 to June 2017, we selected 140 patients with CT-guided percutaneous lung biopsy of cancer center at Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School, by convenience sampling. All of the patients were randomly divided into observation group and control group, 70 cases in each group. Patients of observation group kept strict bed rest for one hour and those of control group for six hours by the routine. We compared the incidence of complication and patients' comfort between two groups after surgery using t test and χ2 test. Results The total of 140 patients were treated with biopsy successfully without chest infection and asphyxia after surgery. There was no statistical difference in the incidences of pneumothorax and bleeding of patients between two groups (χ2=0.341, 0.119; P>0.05) ; the comfort of observation group was superior to that of control group six hours after biopsy with a significant difference (t=9.683, P<0.01) . Conclusions The time of postoperative strict bed rest shorten to one hour among patients with CT-guided percutaneous lung biopsy does not increase the incidence of complications after surgery and makes patients feel more comfortable.
