Gastric pH in Intubated Children

Untersuchung Des Magen-pH in Intubationsanästhesie Bei Kindern

Fasting (according to ASA, ESA or institutional guidelines) is an important strategy to minimize the risk of regurgitation, vomiting and pulmonary aspiration during general anaesthesia; the effect of fasting time for clear fluid on gastric pH in children is goal of this study and can be investigated in children undergoing elective procedures in intubation anaesthesia without inconvenience or additional invasive procedure and hence without additional risk

Hypotheses: Gastric pH is higher in children that drink until 1 hour before anaesthesia induction than in those that drink until 2 hours before anaesthesia induction

Inclusion Criteria:

• age > 1 / <= 16 years
• ASA class I or II
• elective surgery requiring general anaesthesia using tracheal intubation

Exclusion Criteria:

• disease or dysfunction of gastrointestinal tract
• chronic diseases or conditions not compatible with ASA class I or II
