IntroductionLaryngeal Mask Airway (LMA) has gained wide acceptance for routine airway management and with increasing emphasis on day care surgery it is widely used. The aim of this study was to assess the effects of mini dose succinylcholine (0.1mg/kg) with semi-inflated cuff on facilitation of laryngeal mask airway insertion in order to achieve more satisfaction yet less complications .MethodsIn a randomized double-blinded study, sixty ASA 1, 2 and 3 patients aged 20-60 years scheduled for urologic surgical procedures were included. Thirty patients received succinylcholine (Group S), and thirty received 0.9% sodium choride as a placebo (Group C).ResultsCoughing occured in 33.3% of patients in the control group and there was no incidence in succ group (P=0.002). Head or limb movement occurred in 70% of the patients in the control group vs. 10% in succ group (P<0.001). Laryngospasm occurred in 36.6 % of the patients in the control group but there was no incidence in succ group (P=0.004). Additional propofol was required in 53% of the patients in control group vs. 10% for succ group (P=0.001). Ease of insertion and first successfull attempt of LMA were achieved in 93.3% and 90% of the patients respectively in group S (P<0.05). Myalgia and sore throat occurred in 66.7 % of patients in the group C in comparison with 33.3% in group S (P=0.06).ConclusionThe combination of propofol with mini dose succinylcholine, provided a significantly better method for LMA insertion, while reduced propofol doses were needed and number of attempts decreased.
