Effect of Oral Carbohydrate on Serum S-100β Protein and Development of Postoperative Delirium in Elderly Patients

August 3, 2017 updated by: SeHee Na, Gangnam Severance Hospital
This study is to evaluate the effects of preoperative carbohydrate intake on perioperative neuroinflammation and development of delirium.

Detailed Description

Perioperative insulin resistance may primarily contribute to development of postoperative delirium in high risk patients. Preoperative administration of oral carbohydrate reduces insulin resistance. The investigators aimed to investigate the influence of carbohydrate loading on the serum level of S-100β, a surrogate marker of delirium, and the incidence of postoperative delirium in elderly patients.

Participant Group / Arm
Intervention / Treatment
Placebo Comparator: Allocated to Placebo group
  1. Patients was administered in hospital
  2. Randomization
  3. Patient was allocated to Placebo group
  4. Patients received 400 mL of water 12 hours before anesthesia and 400 mL 2 hours before anesthesia.
Dietary supplement: Allocated to Placebo group
Patients received 400 mL of oral flavored water (Placebo) 12 hours before anesthesia and 400 mL 2 hours before

Experimental: Allocated to Carbohydrated group
  1. Patients was administered in hospital
  2. Randomization
  3. Patient was allocated to Carbohydrated group
  4. Patients received 400 mL of oral isotonic glucose (No NPO®, Daesang, Korea) 12 hours before anesthesia and 400 mL 2 hours before. CHL composition was standard: 12.5 g of carbohydrate per 100 mL, 12% monosaccharide, 12% disaccharide, 76% polysaccharide, 250 mOsm/kg and 50 kcal.
