Background: Supraglottic airway devices now have an established place in pediatric anesthesia practice. The laryngeal tube suction (LTS) II, a recent revision of the LTS, has very few studies evaluating its use in pediatric patients. The aim of this study was to compare insertion and ventilation profiles of the LTS-II size 2 and the ProSeal™ Laryngeal Mask Airway (PLMA) size 2 in pediatric patients undergoing elective surgeries. Materials and Methods: A randomized prospective study was conducted in 100 children aged 2–5 years between 12 and 25 kg weight, of the American Society of Anesthesiologists physical status I and II scheduled for routine elective surgeries of <90 min duration. They were randomly divided into two groups of 50 each, depending on the device inserted, and a standard protocol for anesthesia was followed. Outcome measures were studied in terms of ease and time of insertion, oxygen saturation (SpO2), oropharyngeal seal pressure (OSP), and ventilation failures. Results: Both groups were well matched in terms of age, weight, and type of surgery. The success rate for the first attempt was 90% for both the LTS-II group and PLMA group. Insertion was found to be easy in the majority of cases in both groups, and there was no statistical difference in blood pressure, heart rate, or SpO2on insertion. However, the OSP was significantly more in LTS-II and PLMA (P < 0.001). There were no clinically important complications in the postoperative period. Conclusions: Pediatric size 2 LTS-II is easy to insert and provides higher OSP compared with same size PLMA in anesthetized and paralyzed children undergoing elective surgery. It is a safe alternative to PLMA in short duration elective surgeries and may be a better device as it provides for higher OSPs.
