Abstract
Objective To observe whether lung ultrasound(LUS)and diaphragm ultrasound can be used to evaluate and intervene in lung ventilation and diaphragm function in patients undergoing abdominal surgery during the recovery period of general anesthesia.Methods This study included a total of 130 patients who underwent elective abdominal surgery in our hospital and were planned to be sent to the post-anaesthesia care unit(PACU).The patients were randomized into ultrasound group(group U)and control group(group N).In group U,LUS and diaphragm ultrasonography were performed at admission in operating room(T0),at admission in PACU(T1),15 minutes after extubation(T2),and at discharge of PACU(T3).LUS score and the diaphragm thickening fraction(DTF)at each time point were recorded and intervention based on the ultrasound results were performed in group U,Conventional resuscitation without ultrasound assessment was used in group N.Arterial blood gas analysis and oxygenation index were recorded at T3 of patients in both groups.The all patients were followed up for seven days after operation for pulmonary complications(PPCs).Results Compared with T0,DTF decreased significantly(P<0.01)and LUS score increased significantly(P<0.01)after T1,T2,and T3 in the U group,and did not return to the preoperative level at T3(P<0.01).Compared with group N,the total number of intervention measures in group U and the number of taking intervention measures in group U at T1 increased(P<0.05).Compared with group N,the incidence of postoperative hypoxemia,extubation time,and PACU lengthof-stay at T3 in the group U were significantly reduced(P<0.01).Conclusion Ultrasound evaluation of lung and diaphragm function can dynamically monitor the ventilation status and diaphragm function recovery degree of patients during anesthesia recovery,enabling timely interventions to improve the recovery of respiratory function in patients undergoing general anesthesia after abdominal surgery.关键词
