Use of LMA Supreme laryngeal mask ventilation in elderly patients undergoing laparoscopic cholecystectomy
Laryngeal mask airway is the most important development in airway management in the past 50 years.
Since 1988, hundreds of millions of cases have been used safely all over the world. In most places, laryngeal mask airway have been identified as one of the main tools for emergency airway.
An institution studied 120 elderly patients undergoing elective laparoscopic cholecystectomy under general anesthesia, randomly divided into SLIPA laryngeal mask group (S group, n=60), and LMA Supreme laryngeal mask group (L group, n=60) . Observe the time of laryngeal mask insertion and the success rate of the first attempt in the two groups. Record the patients before induction of anesthesia (T0), immediately after successful laryngeal mask insertion (T1), 5 minutes after laryngeal mask insertion (T2), immediately after laryngeal mask removal (T3), and 5min after laryngeal mask removal (T4). Heart rate (HR) and mean arterial pressure (MAP); record the patient’s peak airway pressure (Ppeak), airway plateau pressure (Pplat), and average airway pressure before the establishment of the pneumoperitoneum and 10 min, 20 min, and 30 min after the establishment (Pmean), minute ventilation (MV), and end-expiratory carbon dioxide partial pressure (PETCO2); and observe the patient’s intraoperative gastric bloating, airway leak, postoperative reflux aspiration, laryngospasm, sore throat, laryngeal mask belt The occurrence of complications such as blood. Results: The average insertion time of the laryngeal mask in group S and group L was 12.9 s and 7.6 s, respectively, and the first attempt success rate was 86.6% and 98.3%, respectively. Compared with group S, group L had significantly lower HR and MAP at T1 and T3 (P<0.05). Postoperative laryngeal mask blood was 21.6% in group S and 3.3% in group L.
Conclusion: Both SLIP and LMA Supreme laryngeal masks can be safely used for ventilation of elderly patients undergoing laparoscopic cholecystectomy, but the success rate of LMA Supreme laryngeal mask placement is higher than that of SLIPA laryngeal masks, and the airway damage is less.
Fushan ALMA is made of imported medical grade silicone and with high volume cuff design, it fits to patient's oropharyngeal structure propely and reduces the pressure to patient's pharyngeal mucosa, increase its comfortability. In addition, ALMA also adopts a unique C-shaped structure and gastric drainage channel, which increases the toughness of the product and reduces the risk of reflux and aspiration.
