Ease of ProSeal laryngeal mask airway insertion in children (after placement) using suction catheter: A comparison with conventional techniques


Full Text PDF


Abstract

Objectives: The ProSeal Laryngeal Mask Airway (PLMA) mostly inserted by finger technique and by an introducer tool method. Recently a newer Suction Catheter Guided (SC) insertion technique has been successfully used in children. We performed a study in children with aims and objective to compare the ease of PLMA insertion using SC and conventional techniques.
Methods: 126 American Society of Anaesthesiologist’s class I and II children in age group of 1-12 years weighing 10-50 kg, admitted in our hospital, undergoing an elective surgery in under general anaesthesia in supine position were included in our study. An appropriate size PLMA was inserted using Suction Catheter, introducer tool or digital technique in Groups SC, I and D respectively (n=42) after induction of general anaesthesia. Correct placement of the PLMA was confirmed by using appropriate clinical tests. Ease of PLMA insertion with hemodynamic response was done by time to insertion, number of insertion attempts to achieve effective ventilation and number of cases which required lateral approach of insertion.
Results: In Group SC, PLMA device was inserted after a single attempt in 41 (97.6%) patients, but PLMA insertion was failed in 5 patients in Group I (11.9%) and 6 patients in Group D (14.3%) even after two attempts, and the difference was statistically significant (p=0.044). Time taken for successful placement was statistically shorter in the SC-guided group (SC 22.5±4.021 seconds, I 31.4± 17.57 seconds, D 27.10±12.9 seconds, p value <0> Conclusion: Suction Catheter guided ProSeal LMA insertion was an easier, faster, more successful and a relatively atraumatic technique which also ensures correct placement of the PLMA in the hypopharynx as compared to the routine conventional PLMA insertion techniques with no hemodynamic pressor response to PLMA insertion using any of the three  techniques.
