简要总结
Intravenous anaesthesia induction is nowadays considered as gold standard, mainly because of the possibility of the rapid therapeutic intervention while having secured i.v. line.
In the paediatric patients, apart from intravenous induction, it is also possible to use in the specific situations inhalation anaesthesia induction with sevoflurane (in the mixture with O2 + air, or O2 + N2O) and secure the i.v. line afterwards in the inhalation anaesthesia. This method is in the paediatric population currently preferred, mainly because of possible fear of the painful venipuncture.
Inhalation anaesthesia induction is possible only in patients without the risk of aspiration/regurgitation of stomach content and in patients without predicted difficult airway. Even if sedative premedication is used, during the inhalation induction excitation stage of the general anaesthesia variably appears, during which hemodynamic sympathoadrenal response and involuntary limbs movement might occur. When deepening inhalation anaesthesia, progression to surgical stage and automatic breathing onset appears. This subsequently facilitates to secure the venous access, without which is is not possible to secure the airway (in exception of the emergency situations - resuscitation).
详细描述
The aim of this prospective observational trial is to compare the duration of inhalation and intravenous anaesthesia induction in paediatric patients, who undergo elective surgical or diagnostic procedures. After the approval of the study by the Ethics Committee of the University hospital Brno and registration of the protocol at clinicaltrials.gov, the duration of inhalation and intravenous anaesthesia induction in the patients undergoing general anaesthesia in the Departement of paediatric anaesthesia and intensive care unit, University Hospital Brno in the term from 1.9.2020 until 30.6.2021 will be measured. Measurement will be done in all patients in the given time period, who will undergo elective surgical or diagnostic procedure. The measurement will begin after the patient's arrival at the operating theatre, after the control of the documentation and beginning of the vital signs monitoring. The measurement will be terminated at the occurence of the first end-tidal carbon dioxide (ETCO2) wave, after securing the airway with laryngeal mask or orotracheal intubation
For the inhalation induction sevoflurane will be used (in the mixture with O2 + air, or O2 + N2O), for the intravenous induction, commonly used induction anaesthetics will be used (propofol, etomidate, ketamine, midazolam).
The type and the dose of the induction anaesthetic agent will be recorded (in the case of inhalation induction the dose of inhalation anaesthetic set on the vaporizer, in the case of intravenous induction the dose in mg/kg body weight).
The type and dose of the sedative premedication will be recorded, the number of attempts needed to secure i.v. line, success rate of securing the i.v. line while using Eutectic Mixture of Local Anesthetics (EMLA) patch and/or Buzzy (vibration device for patient distraction), the number of attempts needed to secure the airway, incidence of adverse events which might occur during anaesthesia induction (tachycardia, bradycardia, bronchospasm, laryngospasm).

时间窗: Intraoperatively
The average duration of inhalation and intravenous anaesthesia induction will be measured, defined as the time since the beginning of monitoring of the vital functions (ECG, pulse oximetry, non-invasive blood pressure measurement) until the first ETCO2 wave.
