Abstract

  Gastric emptying rate is an interesting value which varies with the kind of consumed liquid. We investigated the gastric emptying rate of various drinks by 13C acetate breath testing. Gastric emptying was measured for mineral water (MW), oral rehydration solution (ORS), and high concentration carbohydrate drink (HCHO). The results showed that the maximum concentration time (Tmax), which is the time to reach a peak value of 13CO2/12CO2 in the expired air relative to the baseline (value before consuming a drink), tended to be fast in the ORS as compared with the MW (P=0.05). Also, the Tmax was significantly faster in the ORS as compared with HCHO (P=0.04). Based on the results of the gastric emptying rate, oral rehydration therapy (ORT) is considered to be a safe oral rehydration method for patients, as well as for anesthesiologists.
