RESUMO
BACKGROUND: After introducing preoperative oral carbohydrate as a part of enhanced recovery after surgery (ERAS) protocols, we assessed the influence of carbohydrate administration on the perioperative blood sugar levels (BS), the variation of vital signs and patients' satisfaction. METHODS: After IRB's approval and obtaining patients' consent, patients were divided into two groups; taking carbohydrate (Group AW) or not (Group NAW). Anesthesia was induced and maintained with total intravenous anesthesia using propofol, remifentanil and rocuronium. We measured BS six times during perioperative period. We also compared blood pressures and heart rates during induction of anesthesia. Moreover, we carried out questionnaire surveys about degree of satisfaction for ERAS among patients and nurses. RESULTS: Heart rates were significantly higher in Group AW (P < 0.05), but there were no significant difference in blood pressures or BS between the groups. Patients in Group AW had more anxiety for surgeries (P = 0.003), but more than 85% of patients and nurses were satisfied with carbohydrates. CONCLUSIONS: The carbohydrate administration had little influence on the perioperative vital signs. However, we gained high reputations from patients and paramedics.
