“…The vocal cords were visible (grade I to II) in 25% and 33.3% in the LTS-D and LTS-II groups respectively. Fiberoptic view of the vocal cords were considerably lower than reported in the literature 5,21 . The cause of this difference is unclear but LTS has two smaller medial orifices.…”

“…Physicians employed the laryngeal tube during scheduled anaesthesia in 36 studies [22–56] with a total of 1,897 patients: the first-pass insertion success rate of these providers was 82.5% (1,452/1,760, 95% CI: 80.7%–84.3%), and the overall-pass insertion success rate was 93.6% (1,594/1,703) (95% CI: 92.4%–94.8%, p < 0.001) (Table 1). Paramedics, paramedic students, and BLS nurses employed the laryngeal tube in an in-hospital setting in 4 studies [57–60] including 151 patients.…”

Background. Emergency airway management (AM) is a priority when resuscitating critically ill or severely injured patients. The goal of this study was to determine the success rates of LT insertion during AM. Methods. Studies that included LT first-pass insertion (FPI) and overall-pass insertion (OPI) success by emergency medical services and in-hospital providers performing AM for emergency situations as well as for scheduled surgery published until July 2014 were searched systematically in Medline. Results. Data of 36 studies (n = 1,897) reported a LT FPI success by physicians of 82.5% with an OPI success of 93.6% (p < 0.001). A cumulative analysis of all 53 studies (n = 3,600) led to FPI and OPI success of 80.1% and 92.6% (p < 0.001), respectively. The results of 26 studies (n = 2,159) comparing the LT with the laryngeal mask airway (LMA) demonstrated a FPI success of 77.0 versus 78.7% (p = 0.36) and an OPI success of 92.2 versus 97.7% (p < 0.001). Conclusion. LT insertion failed in the first attempt in one out of five patients, with an overall failure rate in one out of 14 patients. When compared with the LT, the LMA had a cumulative 5.5% better OPI success rate.

Comparison of laryngeal tube suction II and proseal LMA™ in pediatric patients, undergoing elective surgery

et al. 2017

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 SpO2 on 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.

Abstract: Both devices provide a secure airway, are similar in clinical utility and are easy to insert. Better airway seal was detected in the PLMA group.
