The physiologic impact of transnasal flexible endoscopy

Abstract

Diagnostic TNFE and topical lidocaine can have an impact on physiologic parameters; however, these changes are unlikely to be clinically significant.

Comprehensive Outcome Researches of Intralesional Steroid Injection on Benign Vocal Fold Lesions

“…[4][5][6] A recent study demonstrated that officebased laryngeal procedures are well tolerated in the outpatient department with limited impact on the hemodynamic profiles. 7 Compared with surgeries in the operating room under general anesthesia, office-based procedures not only avoid potential risks and discomforts associated with general anesthesia but also offer the advantages of real-time monitoring of vocal function and considerable savings of medical expenses. [8][9][10] A number of studies have advocated the potential role of vocal fold steroid injection (VFSI) for the treatment of benign vocal fold lesions.…”

Hemodynamic Parameters during Laryngoscopic Procedures in the Office and in the Operating Room

“…8,12 Our study showed a significantly higher rate of severe hemodynamic effects in the OR when compared with the office setting. Specifically, it appears that severe hypertension occurs frequently in the OR.…”

Premedication Methods in Nasal Endoscopy: A Prospective, Randomized, Double-Blind Study

“…Even though clinicians suppose that topical decongestants cause hypertension and reflex bradycardia, there are not many studies supporting this [7]. Similarly, NE may also increase pulse rate and arterial blood pressure [4]. However, as clinicians, we use decongestant sprays and perform endoscopies relatively often, but do not observe these changes as often as supposed.…”

“…For the patients, NE is a painful and uncomfortable procedure [3]; for the physicians, the disadvantages are prolonged procedure duration and limited view of nasal passages due to hypertrophic and swollen turbinates. In addition, some physiological changes such as acceleration of pulse rate and increase of blood pressure have been associated with NE [4]. …”
