Surgery Clinical Trial
Official title:
Study of Preoxygenation Quality Prior to General Anesthesia in Emergency Surgery
Preoxygenation prior to general anaesthesia prolongs safe apnea time. Proper preoxygenation
is always a challenge in emergency surgery.
The aim of our study is to estimate problems encountered during preoxygenation, their risk
factors and ways of solving them.
Factors, that are associated with compromised preoxygenation will be determined during our
study. Pulse oximetry data and end-tidal oxygen concentration values will be evaluated in
association with risk factors for insufficient anaesthesia face mask seal, difficult
intubation, preoxygenation techniques used, comorbidities, physical status, hemodynamic and
laboratory measures.
Parameters analysed:
- Preoperative: medical history, physical examination, laboratory findings, anthropometric
data
- Intraoperative: preoxygenation equipment and method used (defined by anaesthesiologist
in charge of the case), oxygenation and haemodynamic values recorded during
preoxygenation and induction of anaesthesia, intraoperative laboratory values (if
obtained)
