“…Each participant in our study received the LMA-Classic with size adjusted by weight and the cuff fully deflated. This treatment is in accordance with earlier research from Jiwon An, et al [6] comparing fully and partially deflated LMA, resulting in a more accurate method if the cuff was fully deflated [7].…”

Background: Laryngeal Mask Airways (LMA) is often performed for airway management. Many insertion techniques of supraglottic airway devices have been described in an attempt to obtain an accurately-positioned and a well-functioning airway. The classic insertion technique, as advised by the manufacturers is frequently used, but this insertion is usually blind without knowing whether the mask sits perfectly, and is often left in position as long as adequate ventilation of the lungs is achieved. Methods: In this double-blind randomized controlled trial, the study subjects (total 106 patients) were divided into two groups, using either videolaryngoscopy-guided or classic blind insertion techniques. The study compared the accuracy of the LMA position based on the Fiberoptic Laryngeal Score (FLS), the clinical score, the number of insertion attempts of the LMA and complications such as a sore throat and blood on the LMA cuff. Result: Correct insertion of the LMA by videolaryngoscope was significantly higher than the use of the classic blind insertion technique based on FLS assessment (79.2% vs 17%, p <0.05) and clinical score (100% vs 88.7%, p < 0.05). The first attempt success insertion rate of LMAs was significantly higher superior in the group using videolaryngoscopy (100% vs 88.7%, p < 0.05). The incidence of sore throat was not statistically significantly different, while for the incidence of blood present on LMA cuffs obtained statistically significant with p value 0.028. Conclusion: Videolaryngoscop is a useful tool for insertion and guiding the LMA in a correct position. The camera on the tip of the video laryngoscope blade provides a wider angle view than that obtained with classic laryngoscopes, and thus we can place LMA in front of the vocal cords more easily.

“…Despite the manufacturers recommendation many anaesthetists inserted the LMA with a partially inflated cuff. Having said this, earlier studies have not confirmed that the insertion technique is associated with POST [29,30]. The anatomy of the pharynx differs between the sexes [31] and it is possible that currently used LMAs are devised to better suit the anatomical features of the male pharynx rather than the female and therefore the lower incidence of POST in men.…”

Gender differences in sore throat and hoarseness following endotracheal tube or laryngeal mask airway: a prospective study

2014

BackgroundPostoperative sore throat and hoarseness are common minor complications following airway manipulation. This study was primarily done to determine gender differences in the incidence of these symptoms and the location of POST after laryngeal mask airway (LMA) and endotracheal tube (ETT).MethodsA total of 112 men and 185 women were included during a four month period. All patients were evaluated postoperatively and after 24 hours about the occurrence of sore throat, its location and hoarseness. If the patients had any symptom, they were followed-up at 48, 72 and 96 hours until the symptoms resolved.ResultsThere was no significant gender difference in postoperative sore throat (POST) and postoperative hoarseness (PH) when analyzing both airway devices together. The incidence of sore throat and hoarseness were higher postoperatively after an ETT than an LMA (32% vs. 19%, p = 0.012) and 57% vs. 33% (p < 0.001) respectively. Significantly more women than men had POST after an LMA (26% vs. 6%, p = 0.004). No significant gender difference was found in either POST or PH after an ETT or in the incidence of PH after an LMA. More patients located their pain below the larynx after an ETT vs. an LMA (24% vs. 4%). Pain above the larynx was more common after an LMA than an ETT (52% vs. 37%).ConclusionsIn a clinical setting where women are intubated with a smaller size ETT than men, there were no significant differences in POST or PH between genders. Additionally, more women than men have POST when an LMA is used. Awareness of POST and PH may help streamline patients in whom the best airway device could be used during anesthesia and surgery.
