Study on nebulized or sprayed lidocaine as anesthesia for esophago-gastro duodenoscopy (EGD)
Endoscopy of the gastro intestinal tract is an invasive technique resulting in gag reflex, bradyarrhythmias and unpleasant symptoms. This study aimed to comparison of the effectiveness; successful completion of the endoscopic procedure of spraying and nebulized lidocaine for patients undergoing endoscopy and patient respone to topical pharyngeal anesthesia (TPA). A total of 220 patients undergoing elective EGD, with a history of neither lidocaine intolerance nor irritable airways due to smoking, chronic obstructive pulmonary disease (COPD), upper respiratory infection, asthma, cardiac and pulmonary diseases and allergy to lidocaine were included. All patients were randomized into two groups: A where 5 puffs (10 mg/puff) of spraying lidocaine were administered four times at 5-minute intervals, up to a total dose of 200 mg, and B-where 250 mg of nebulized lidocaine was administered via a nebulization. The co-researcher assessed the ease of esophageal instrumentation as either difficult, poor, fair or excellent. Both the endoscopist and the patients expressed their satisfaction by using the numerical rating scale The endoscopist expressed her satisfaction with instrumentation, which showed no significant difference between group A and group B as 83.6+8.3 and 81.5+10.6, respectively. However, nebulized lidocaine had significant advantages over spraying lidocaine, with better acceptance in patients undergoing EGD. Nebulized Lidocaine is equally effective to spraying lidocaine in terms of endoscopist response to EGD but is more tolerable to patient in terms of administration, taste of medication, sensation and post procedural sore throat and dysphagia.
