- Brief Summary
Traditionally, Fasting for more than 8 hours before operation is administered to reduce the risk of reverse flow and aspiration. ASA guidelines suggest a 2-hour fasting for clear fluid in healthy people before elective surgery. But in delivery women, the gastric emptying time is affected by the physiological change. This study is a prospective randomized controlled study to investigate the gastric emptying time of high energy digestible foods in delivery women, and the effect of high energy digestible food given before surgery on the comfort and metabolism of women undergoing Cesarean section. In the first step, 60 women in delivery room whose gastric volume less than 3.81 cm2 are randomly divided into three groups, 20 cases in each group. The experimental group (Group E1) is treated with high energy digestible food 300ml, Group G1 is given 5% glucose injection 300ml and Group N1 is given normal saline 300ml. The gastric volume was determined by ultrasonography once every hour until gastric volume less than 3.81cm2, and the time of gastric emptying was determined. The second step was to recruit 80 cases of full-term elective cesarean section. They were randomly divided into four groups, 20 cases in each group. The experimental group (Group E2) was given high energy digestible food 300ml before the time of gastric emptying found in the first step , Group G2 is given 5% glucose injection 300ml and Group N2 is given normal saline 300ml, while the control group (Group C2) was not given any diet. After admission to the operation room, the volume of the stomach was measured by ultrasound, and the differences of comfort, body temperature, shivering, blood glucose and postoperative anal exhaust time between the two groups were observed. This study is going to investigate the gastric emptying time of high energy digestible foods in delivery women, and the effect of high energy digestible food on the comfort, body temperature and blood glucose of women undergoing Cesarean section, so as to provide a good basis for reducing the surgery stress in women undergoing Cesarean section.
- Detailed Description
This study is a prospective randomized controlled study to investigate the gastric emptying time of high energy digestible foods in delivery women, and the effect of high energy digestible food given before surgery on the comfort and metabolism of women undergoing Cesarean section.
In the first step, 60 women in delivery room are enrolled, who are full term singleton pregnancy subjects ranging 18 to 50 years old and fasting for more than 8 hours. They are randomly divided into three groups, 20 cases in each group.
The experimental group (Group E1) is treated with high energy digestible food 300ml, Group G1 is given 5% glucose injection 300ml and Group N1 is given normal saline 300ml. The gastric volume was determined by gastric antrum cross-sectional area (CSA) measured with ultrasonography before drinking and once every hour after drinking. Once CSA is less than 3.81 cm2, the time is recorded as gastric emptying time of the woman. The overall gastric emptying time of high energy digestible food is determined with the 90 percentile gastric emptying time of women drinking high energy digestible food.
The second step was to recruit 80 cases of full-term elective cesarean section. They were randomly divided into four groups, 20 cases in each group. The experimental group (Group E2) was given high energy digestible food 300ml before the time of gastric emptying found in the first step, Group G2 is given 5% glucose injection 300ml and Group N2 is given normal saline 300ml, while the control group (Group C2) was not given any diet. After admission to the operation room, the volume of the stomach was measured by ultrasound, and the differences of comfort, body temperature, shivering, blood glucose and postoperative anal exhaust time between the two groups were observed.
This study is going to investigate the gastric emptying time of high energy digestible foods in delivery women, and the effect of high energy digestible food on the comfort, body temperature and blood glucose of women undergoing Cesarean section, so as to provide a good basis for reducing the surgery stress in women undergoing Cesarean section.

- Primary Outcome Measures
Name Time Method body temperature the time point when newborn delivers and 1 hour after surgery Maternal tympanic temperature measured by infrared ear thermometer
- Secondary Outcome Measures
Name Time Method flatus time up to 48 hours after surgery The time point when anal exhaust restarts after surgery
Maternal comfort up to 24 hours after surgery Maternal comfort is measured by the women undergoing Cesarean section with visual analogy scale. Respondents mark the location on the 10-centimeter line corresponding to the amount of comfort they experienced.
Incidence and severity of shivering up to 1 hour after surgery Incidence and severity of shivering is assessed with Wrench's Grade.
pain after surgery up to 48 hours after surgery Maternal pain is measured by the women undergoing Cesarean section with visual analogy scale. Respondents mark the location on the 10-centimeter line corresponding to the amount of pain they experienced.
nausea and vomitting after surgery up to 24 hours after surgery The severity of postoperative nausea and vomitting is assessed with CTCAE v4.0.
