Description of intervention(s) / exposure
Patients are randomly assigned to have 10% lidocaine spray (approximately 30mg) or normal saline in their throat on arrival, approximately 3 minutes before upper gastrointestinal endoscopy.

Placebo

Outcomes
Primary outcome [1] 261997 0
The overall ease of the endoscopy assessed by endoscopists via rating scales.
Rating scales are used to assess by endoscopists. The parameters include patients' ability to follow verbal command, show somatic response after anesthesia, have any coughs, hiccups, or gag reflex on esophageal intubation and also the overall ease of esophageal intubation and satification of the procedure by endoscopists.
Timepoint [1] 261997 0
at the end of the endoscopy
Secondary outcome [1] 268930 0
Hemodynamic changes during endoscopy (eg heart rate, non-invasive blood pressure, oxygen saturation on 3L oxygen nasal prong, BIS index) and the requirement of airway maneuver
Timepoint [1] 268930 0
The hemodynamic values (HR, BP, BIS, SpO2) are recorded on arrival, then every 2 min afterwards during endoscopy and again on departure.

Eligibility
Key inclusion criteria
1. All participants who sign the consent and agreement form
2. All participants who are admitted for upper gastrointestinal endoscopy under general anesthesia with total intravenous anesthesia
3. All participants who are between the age of 20 and 69
Minimum age
20 Years
Maximum age
69 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. young age <20 years; old age >69 years
2. participants who are reported to have allergic reaction to the anesthetic agents used in the study (lidocaine)
3. pregnant women or who are breastfeeding

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All patients who fullfill the inclusion criteria are recruited. The consented participants are allocated to have either lidocaine spray or normal saline spray sprayed onto their throat before the endoscopy via a central randomization by computer . Both the patients and endoscopists are blinded whereas the anesthetist on site is to administer the spray and is aware of the allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software
Masking / blinding
Blinded (masking used)

Summary
Brief summary
The use of topical pharyngeal anesthesia has long been controversial among the anesthetists and no evidence has well supported the use of the spray. The use of lidocaine spray is not without adverse effects, which include aspiration pneumonia, methemoglobinemia and anaphylaxis. Most of the patients undergo endoscopies under general anesthesia and theoretically should not require pharngeal spray to suppress pharyngeal reflexes during the procedure. The aim of the study is determine whether the use of the spray is necessary in patients under deep sedation/general anesthesia. Deep sedation is achieved by total intravenous anesthesia (TIVA) with propofol.
