Cricoid pressure with the Truview Evo2(TM) laryngoscope improves the glottic view.
Summary of "Cricoid pressure with the Truview Evo2(TM) laryngoscope improves the glottic view."
The Truview Evo2â„¢ laryngoscope blade is designed to improve glottic view. This study was designed to evaluate the effect of cricoid pressure (CP) on laryngeal view and the ease of orotracheal intubation with the Truview Evo2 laryngoscope.
In this randomized controlled trial, 50 patients (American Society of Anesthesiologists physical status I-II, aged 18 to 60Â yr) scheduled for elective surgery were enrolled. After induction of anesthesia and muscle paralysis, laryngoscopy was performed using the Truview Evo2(TM) laryngoscope with the patient's head in the neutral position. In Group 1, the percentage of glottic opening (POGO) score was evaluated first without CP, then with CP, and CP was applied for intubation. In Group 2, the POGO score was evaluated first with CP, then without CP, and no CP was applied for intubation. Time to intubation and number of attempts required for intubation were also recorded.
In 50 patients, the mean (standard deviation) POGO view obtained with the application of CP was 93% (10%) compared with 81% (19%) in patients without CP (PÂ <Â 0.01). Times to intubation were similar in the two groups: 14.2 (6.6) sec vs 14.0 (9.3) sec in Groups 1 and 2, respectively (PÂ =Â 0.924). Sixteen percent of patients in Group 1 required a second attempt at tracheal intubation, while only 4% of patients in Group 2 required a second attempt (PÂ =Â 0.162).
When using the Truview Evo2(TM) laryngoscope with the patient's head in the neutral position, application of CP improves the glottic view. This approach is not associated with increased difficulty in intubation.

Medical and Biotech [MESH] Definitions
A selective and potent serotonin-2 antagonist that is effective in the treatment of a variety of syndromes related to anxiety and depression. The drug also improves the subjective quality of sleep and decreases portal pressure.
The blood pressure in the VEINS. It is usually measured to assess the filling PRESSURE to the HEART VENTRICLE.
Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more.
A dideoxynucleoside compound in which the 3'-hydroxy group on the sugar moiety has been replaced by an azido group. This modification prevents the formation of phosphodiester linkages which are needed for the completion of nucleic acid chains. The compound is a potent inhibitor of HIV replication, acting as a chain-terminator of viral DNA during reverse transcription. It improves immunologic function, partially reverses the HIV-induced neurological dysfunction, and improves certain other clinical abnormalities associated with AIDS. Its principal toxic effect is dose-dependent suppression of bone marrow, resulting in anemia and leukopenia.
The blood pressure as recorded after wedging a CATHETER in a small PULMONARY ARTERY; believed to reflect the PRESSURE in the pulmonary CAPILLARIES.
