Application of dual lumen gastrointestinal tube with air insufflation technique in mechanical ventilation patients with intra-abdominal hypertension / 中华急诊医学杂志

ABSTRACT

Objective To investigate the application effect of nasal gastrointestinal double lumen catheter tube placement with air insufflation in mechanically ventilated patients with intra-abdominal hypertension.Methods A total of 20 patients with intra-abdominal hypertension were randomly divided into control group and observation group (n=10 in each group).Patients in control group received indwelling nasogastric tube for decompression and indwelling nasal intestine tube by air insufflation for enteral nutrition support .Patients in observation group received the dual lumen gastrointestinal tube for decompression and enteral nutrition support.The time required for catheterization,changes in intra-abdominal pressure before and after air insufflation,catheter success rate at one attempt,pain scores of patients to catheter operation, duration of decompression,enteral nutrition start time and the duration of mechanical ventilation were compared between two groups.Results The time required for catheterization,catheter air insufflation volume in observation group were significantly lower than those in control group (P 0.05 ).Conclusions The technique of air insufflation has higher success rate for Indwelling nasal intestine tube in mechanically ventilated patients with intra-abdominal hypertension,and this method is safe and reliable,dual lumen gastrointestinal tube can improve patients'comfort,shorter catheterization time and reduce catheter air insufflation volume.
