ObjectiveTo assess the clinical efficacy of sonography guided Freka Trelumina placement by stylet displacement in patients with severely impaired gastric emptying. MethodsTwenty-two patients with severely impaired gastric emptying monitored in the Intensive Care Unit from January 8 to May 18, 2016 were chosen to be our study subjects. Freka Trelumina was placed under ultrasonic guidance, and the guide wire displacement was used to determine the location of the catheter. We recorded whether the patient had an intra-gastric injection of warm water, the manual pushing times before the catheter passed through the pylorus, whether the operation succeeded, the time spent on guiding the placement, and the catheter depth. The pros and cons of the method in clinical use, and whether fasting state helped reduce the operating time were analyzed. ResultsAmong the 22 patients, 20 had a successful Freka Trelumina placement, and the success rate was 91%. The number of manual pushing before the catheter passed through the pylorus was 1 in 4 cases (20%), 2 in 5 (25%), and equal to or more than 3 in 11 cases (55%). The catheter could be seen in the third part of duodenum only in 9 cases (45%). The mean placement procedure lasted (20.35±12.93) minutes for the successful cases. The time spent in the 11 patients with empty stomach was (15.00±9.87) minutes, less than (26.89±14.45) minutes in those 9 post prandial patients (P＜0.05). ConclusionsWith stylet displacement to determine the location of the catheter, sonography guided Freka Trelumina placement has a high success rate. Ultrasonic guidance facilitates the insertion of the tubes in critically ill patients. For patients with empty stomach, it may help reduce the operating time.
