Abstract
Objective:To investigate the Clinical practice value of nitrous oxide inhalation and intravenous propofol and midazolam sedation in transnasal gastroscopy.Method:From December 2012 to April 2014, two hundred patients receiving painless transnasal gastroscopy on a voluntary basis were selected in Endoscopy center, The First People’s Hospital of GuiYang. Patients were divided into two groups: Group-1 consisted of one hundred patients sedated by nitrous oxide inhalation and Group-2 consisted of one hundred patients sedated by intravenous propofol and midazolam. Patients were then examined by transnasal gastroscopy. Patient blood pressure, heart rate, pulse rate and oxygen saturation before, during and after gastroscopy were recorded for both groups. The duration of the gastroscopy and the time of awakening were also recorded. After examination, the patients were asked to assess the level of discomfort experiences during the gastroscopy procedure.Results:All patients successfully underwent the transnasal gastroscopy. There were 57 males and 43 females in the nitrous oxide inhalation group with an average age of 43.11±8.27 years. The average duration of examination and time of awaking in the nitrous oxide inhalation group was of 152.7±9.80 secs and 50±7.89 secs respectively. For the intravenous propofol and midazolam sedation group, there were 53 males and 47 females with an average age of 41.26±7.98 years. The average duration of examination and time of awaking in the intravenous propofol and midazolam sedation group was of 149.07±10.25 seconds and 390±20.89# seconds respectively. The two groups showed no significant difference in the duration of examination. There was no difference in the age or sex. The former had a less significant impact on heart rate, oxygen saturation and blood pressure, while the intravenous propofol and midazolam sedation decreased blood pressure dramatically and this effect persisted after examination.Conclusion:Nitrous oxide inhalation has higher safety and tolerance with a brighter application prospect for transnasal gastroscopy.
Highlights
Painless endoscopy is widely used in the clinic
We compared the effects of nitrous oxide inhalation and intravenous propofol and midazolam sedation in transnasal gastroscopy
The Visual analog scale (VAS) score was 2.01±0.01 in the nitrous oxide inhalation group and 2.32±0.02 in the intravenous propofol and midazolam sedation group, indicating no significant difference (p>0.05)
Summary
Painless endoscopy is widely used in the clinic. The most common intravenous anaesthetics inhibit respiration and circulation, with intravenous anesthesia usually requiring continual assessment and monitoring by an anaesthetist. Nitrous oxide/oxygen inhalation sedation has proved to be a safe and effective approach for controlling pain and anxiety. Convenience, less adverse events and lower costs, nitrous oxide/oxygen inhalation sedation has become the common sedation technique for pains induced by abortion and dental treatment.[1,2,3] We compared the effects of nitrous oxide inhalation and intravenous propofol and midazolam sedation in transnasal gastroscopy. The safety and effectiveness of the two kinds of anaesthesia techniques were compared
