Objective: To design an instrument for steadying instrument handling during microlaryngeal surgery using an operating laryngoscope. Method: Our device design takes its cue (pun intended) from professional billiards players like our very own Efren "Bata" Reyes. The laryngeal tiririt (bridge or rake) draws inspiration from the billiards bridge (locally known as tiririt) used to extend the player's reach when the cue ball is too far to make an accurate shot. Setting: The laryngeal tiririt was used and tested by senior residents in microlaryngeal surgeries done in our institution. Result: The laryngeal tiririt greatly improved the accuracy required in laryngeal surgeries without adding up huge set up or expensive equipment. (Author)

BACKGROUND: The effects of the levering laryngoscope (McCoy laryngoscope) on the laryngoscopic view classified by the Cormack and Lehane were investigated in this study. METHODS: The laryngoscopic view with the levering laryngoscope blade in neutral and best position were recorded respectively and analysed statistically. RESULTS: 109 laryngoscopic views were grade 1 or 2 and 12 were grade 3 or 4 in the neutral position with the McCoy blade. Only three patients were grade 3 or 4 in its best position and the others grade 1 or 2. The reduction in the incidence of difficult laryngoscopic view (grade 3 or 4) using the levering laryngoscope in its best position was statistically significant (p<0.01). CONCLUSIONS: Levering laryngoscope improves laryngoscopic view and also reduces the incidence of difficult intubation. So, we suggest that it is an useful instrument for the anesthesiologists in the difficult tracheal intubation.

BACKGROUND AND OBJECTIVES: Although suspension laryngoscopy is a very common procedure in the otolaryngoloical field and suspension force (Fs) is suspected to be related with the complications or laryngeal exposure, Fs has not been objectively measured yet. The objective of this study is to measure suspension force continuously during suspension laryngoscopy. SUBJECTS AND METHOD: Sixteen patients who had undergone laryngoscopic surgery were evaluated. The value measured with a load cell during the procedure was converted to Fs with calculation. The maximum force (Fsmax) and the mean force (Fsmean) were evaluated. The angle between the laryngoscope and the chest holder(angle alpha), and the angle between the chest holder and the horizontal plane (angle beta) were gauged. RESULTS: The mean values of Fsmax and Fsmean were 14.2 and 25.5 kgf, respectively. The mean values of angle alpha and angle beta were 124.0+/-4.3 degrees, and 19.0+/-2.6 degrees, respectively. CONCLUSION: The continuous measurement of the suspension force was executed successfully and quantitatively with a simple method.

BACKGROUND: The Glidescope(R) videolaryngoscope is a new device for tracheal intubation that provides an improved view of the larynx. This study was performed to compare the Glidescope with the McGrath videolaryngoscope in terms of time to intubation (TTI) and number of attempts. METHODS: Patients were randomly allocated to one of two groups, Glidescope or McGrath group, by using computer-generated numbers. Tracheal intubation was attempted by an anesthesiologist with extensive experience using these two devices. The operator recorded ease of visualization of glottic structures based on the classification described by Cormack and Lehane. Number of failures, number of attempts and their duration, total intubation time, and events during the whole procedure were recorded. The duration of one attempt was defined as the time elapsed between picking up the endotracheal tube and verification of tracheal intubation with visualization of three expiratory carbon dioxide waveforms. TTI was defined as the sum of the duration of all intubation attempts (as many as three), excluding preoxygenation procedures. RESULTS: TTI was significantly shorter for the Glidescope(R) compared to the McGrath(R) laryngoscope (40.5 vs. 53.3 s, respectively, P < 0.05). However, glottic views obtained at intubation were similar between the two groups. Number of intubation attempts was not significantly different between the two groups (1.03 +/- 0.19 vs 1.10 +/- 0.32, respectively) (mean +/- SD). CONCLUSIONS: Study results demonstrated that the Glidescope reduced total intubation time in comparison with the McGrath, in terms of TTI in patients with normal airways.

Retrograde intubation is an alternative option for gaining airway access for patients with a difficult airway.We report a successful management of a kinked J-tip guidewire within a tracheal lumen with flexible fiberoptic laryngoscope in a patient with type II odontoid fracture.It is helpful to adjusting the depth of angiocatheter and handling of J-tip guidewire if J-tip guidewire does not come out into the oral cavity at the expected length during retrograde intubation.

OBJECTIVE: To compare the effectiveness of the GlideRite stylet with the conventional malleable stylet (CMS) in endotracheal intubation (ETI) by the Macintosh laryngoscope. METHODS: This study is a randomized, crossover, simulation study. Participants performed ETI using both the GlideRite stylet and the CMS in a normal airway model and a tongue edema model (simulated difficult airway resulting in lower percentage of glottic opening [POGO]). RESULTS: In both the normal and tongue edema models, all 36 participants successfully performed ETI with the two stylets on the first attempt. In the normal airway model, there was no difference in time required for ETI (TETI) or in ease of handling between the two stylets. In the tongue edema model, the TETI using the CMS increased as the POGO score decreased (POGO score was negatively correlated with TETI for the CMS, Spearman’s rho=-0.518, P=0.001); this difference was not seen with the GlideRite (rho=-0.208, P=0.224). The TETI was shorter with the GlideRite than with the CMS, however, this difference was not statistically significant (15.1 vs. 18.8 seconds, P=0.385). Ease of handling was superior with the GlideRite compared with the CMS (P=0.006). CONCLUSION: Performance of the GlideRite and the CMS were not different in the normal airway model. However, in the simulated difficult airway model with a low POGO score, the GlideRite performed better than the CMS for direct laryngoscopic intubation.

BACKGROUND: Difficult intubation is one of the major causes of anesthetic emergencies or catastrophe. Through the years, new and sophisticated devices have been developed to aid in endotracheal intubation. These devices are expensive and much skill is needed to master its use. It is this light that we have designed the J-Tex Laryngeal Mirror, an inexpensive accessory tool for endotracheal intubation METHODS: This study was done on 200 patients divided into 2 groups who were scheduled for surgery under general anesthesia. We compared Group I that had the J-Tex attached to the laryngoscope to Group II which used the laryngoscope alone RESULTS: Total intubation time was shorter with the J-Tex group. Success rates were comparable between the 2 groups. However, there was a higher success rate with the J-Tex group in patients who had a difficult airway (Mallampati III) CONCLUSION: We can proudly say that the J-Tex Laryngeal Mirror is an effective accessory tool for endotraceal intubation.
