Application of gastrointestinal ultrasound to monitor gastric residual volume in nutritional treatment of patients with severe neurological mechanical ventilation
Objective To investigate the application value of gastric residual volume(GRV)monitoring by gastrointestinal ultrasound in nutritional treatment of patients with severe neurological mechanical ventilation.Methods A total of 92 patients with stroke and respiratory failure in intensive care unit received mechanical ventilation in Bozhou People's Hospital,Anhui Province from January 2021 to December 2022 were selected and divided into control group and observation group according to random number table method,with 46 cases in each group.GRV of the control group was monitored by gastric tube withdrawal method,and nutritional treatment was given according to GRV monitoring results;GRV of the observation group was monitored by gastrointestinal ultrasound,and nutritional treatment was given according to GRV monitoring results.The incidence of reflux,aspiration,and enteral nutritional intolerance in the two groups were observed,and the feeding interruption rate,feeding time,and nutritional indexes of the two groups were compared.Results The reflux rate,the incidence of enteral nutritional intolerance,and the rate of feeding interruption in the observation group were lower than those in the control group,and the time to reach the target feeding was shorter than that in the control group,the differences were statistically significant(P＜0.05).After three days of intervention,serum prealbumin and albumin levels in two groups were higher than those before intervention,and those of observation group were higher than those of control group,the differences were statistically significant(P＜0.05).Conclusion Gastrointestinal ultrasound monitoring of GRV can improve the enteral nutrition tolerance of patients with stroke complicated with mechanical ventilation of respiratory failure,reduce the rate of feeding interruption,achieve the target feeding amount early,and improve the nutritional status of patients.
