A Comparison of The Use of Tubeless Tire Model New Generation Baska Mask ® LMA and Classic LMA in Terms of Ease-of-Use and Patient Comfort

This study aimed to compare Baska Mask laryngeal mask airway (LMA) with classic LMA in terms of clinical performance, ease of use, and patient comfort. The duration of placement was compared between the groups as the primary outcome. Comparisons were also made for the number of LMA entry attempts, hemodynamic parameters. and postoperative complications. The study included 66 patients. The patients were randomly separated into two groups using the sealed-envelope method. After general anesthesia induction, a new LMA (Baska Mask) or a classic LMA was placed in the mouth of all the patients. The heart rate, blood pressure, mean and peak airway pressure, and amount of ventilation leakage were recorded throughout the surgery. The patients were examined for the presence of blood smears after removing the LMA. One hour after the surgery, an anesthetist blinded to the groups asked all the patients whether they had throat pain. The duration of LMA placement was determined as 14.5 s for classic LMA and 16.0 s for new LMA, with no significant difference between the groups ( P = 0.117). The number of attempts at entry was similar in both groups ( P = 0.741). The mean and peak airway pressure measurements 5 min after LMA placement were statistically significantly different between the groups ( P < 0.05), with higher values in the new LMA group. No blood smears were observed in the patients using new LMA, while blood smears were determined in seven patients in the classic LMA group ( P = 0.012). The results of this study showed that an adequate, safe open airway was provided throughout the surgery in both groups. Despite no significant difference with respect to ease of use, the Baska Mask was thought to be more advantageous than LMA in terms of patient comfort.
