Gastric pH in Intubated Children - Part Two

Not Applicable
Completed
Conditions
Preoperative Fasting
Interventions
Procedure: clear fluid ingestion
Registration Number
NCT02603094
Lead Sponsor
University Children's Hospital, Zurich
Brief Summary

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 general anaesthesia and intubation without inconvenience or additional invasive procedure and hence without additional risk

Hypotheses: Gastric pH is higher in children that drink clear fluids until premedication before anaesthesia induction than in those that drink until 2 hours before anaesthesia induction

Primary Outcome Measures
NameTimeMethod
gastric pHwithin 10 min after tracheal intubation

gastric pH is measured from gastric contents which is sampled in a syringe via an orogastric tube immediately during anaesthesia after tracheal intubation induction; suctioning of the stomach after intubation is a procedure routinely performed in every intubation child in our institution

Secondary Outcome Measures
NameTimeMethod
Postoperative Nausea and Vomiting (PONV) in recovery unitrecovery period, on the average within 90 minutes after end of anaesthesia
subjective feeling of hunger/thirstbaseline

subjective feeling of hunger/thirst given as "yes" or "no" answer

Behaviour during recovery periodrecovery period, on the average within 90 minutes after end of anaesthesia

Rating Scale1-5 by blinded nurse (5: severely agitated/emergence delir with subsequent drug therapy, 4: agitated/emergence delir; 3: slightly agitated; 2: complaining pain but cooperative; 1: cooperative)

Nurse's Impression of patient's satisfactorybaseline

subjective feeling of the Nurse regarding patient's satisfactory given as rating scale from 1 to 4

Behaviour during anaesthesia inductionon the average within 20 minutes after arrival of patient in operating theatre

Rating scale1-5 by (blinded) anaesthetist: 1: cooperating - 2: anxious but cooperating - 3: hostile - 4: crying - 5: agitated/fighting

gastric aspirate volumewithin 10 min after tracheal intubation

gastric aspirate volume is the amount of gastric contents which is sampled in a syringe via an orogastric tube immediately during anaesthesia after tracheal intubation induction; suctioning of the stomach after intubation is a procedure routinely performed in every intubation child in our institution
