Study on the efficacy of preoperative enhanced information support combined with PMRT in patients undergoing thoracoscopic pneumonectomy

ObjectiveTo investigate the effect of preoperative enhanced information support combined with progressive muscle relaxation training(PMRT) on anxiety in patients undergoing thoracoscopic pneumonectomy.

MethodsPatients who underwent thoracoscopic pneumonectomy were selected as the research objects and randomly divided into the combined group and the control group, with 30 patients in each group.The control group received a routine preoperative operating room visit plan, and the combined group received preoperative enhanced information support combined with PMRT intervention.The changes in anxiety level, sedative-restlessness, blood pressure, heart rate, length of anesthesia recovery room, and hospital stay were compared between the two groups before and after intervention.

ResultsThere were no significant differences in anxiety level, heart rate, systolic blood pressure and diastolic blood pressure between the two groups at routine visit 1 day before surgery(P>0.05).Anxiety level, heart rate, systolic blood pressure and diastolic blood pressure in the operating room waiting room and out of the operating room in the combined group were lower than those in the control group(P < 0.01).There were significant differences in anxiety level, heart rate, systolic blood pressure and diastolic blood pressure between the two groups before and after surgery(P < 0.05 to P < 0.01), and all indexes in the combined group showed a trend of increasing in the operating room waiting room and decreasing when leaving the operating room(P < 0.05 to P < 0.01).However, in the control group, all indexes in the operating room waiting room and out of the operating room were higher than 1 day before surgery(P < 0.01), and there was no statistically significant difference between waiting room and exit room(P>0.05).There was no statistically significant differences in the incidence of agitation and hospital stay between the two groups(P>0.05).However, the stay duration in the recovery room in the combined group was significantly lower than that in the control group(P < 0.01).

ConclusionsPreoperative enhanced information support combined with PMRT can effectively relieve preoperative and postoperative anxiety in patients undergoing thoracoscopic pneumonectomy.
