Blockbuster LMA, Baska Mask, Laparoscopic Cholecystectomy
Conditions
Brief summary
This study aimed to compare the performance and safety profiles of two supraglottic airway devices (SADs), the Blockbuster laryngeal mask airway (LMA) and the Baska Mask (BM), in patients underwent laparoscopic cholecystectomy (LC).
Detailed description
Laparoscopic surgery has become increasingly prevalent across numerous surgical disciplines due to the well-established benefits it offers over traditional open procedures. Laparoscopic cholecystectomy (LC), the surgical removal of the gallbladder, stands out as one of the most frequently performed laparoscopic operations worldwide. Supraglottic airway devices (SADs) play a crucial role in airway management algorithms, serving as viable alternatives in both anticipated and unanticipated difficult airway situations. The laryngeal mask airway (LMA) can be utilized to establish a routine airway during general anesthesia or, less frequently, as a conduit for tracheal intubation. Newer, improved LMA designs incorporate cuffs that provide higher sealing pressures than classic LMAs, while also allowing for the venting of gastric contents through a dedicated drain tube. The Baska Mask (BM), a second-generation SAD, features a non-inflatable cuff that is continuous with the airway channel, thereby inflating with positive pressure ventilation to improve cuff seal.
Interventions
DEVICEBlockbuster LMA
The LMA was inserted using the recommended technique, with the patient's head in the sniffing position. The appropriate size was selected based on body weight (size 3 for 30-50 kg, size 4 for 50-70 kg)
DEVICEBaska Mask
The BM was inserted by opening the mouth, avoiding the tongue, and negotiating the palatopharyngeal curve using the hand-tab.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Oropharyngeal leak pressure | 30 min after insertion | Oropharyngeal leak pressure was measured Just after insertion and 30 min after insertion. |
