COMPARISON OF TWO DIFFERENT INSERTION TECHNIQUES WITH LMA IN ADULTS- STANDARD VERSUS ROTATIONAL.
Journal Title: IJAR-Indian Journal of Applied Research - Year 2018, Vol 8, Issue 12
Abstract
Introduction The Laryngeal Mask Airway is a useful airway device for airway management during general anesthesia and for emergency situations. The use of disposable more rigid LMAs is increasing and may be other insertion techniques will be described for these LMAs in the future. 90 degrees rotational or lateral techniques might be considered as the best ways for LMA insertion compared to the standard technique in compared to the success rate of insertion and complications hence we a study to assess the best technique of insertion of LMA with high success rates and less adverse events. Materials and Methods A prospective, observational study was done after obtaining ethical committee clearance and written informed consent 100 Adult patients, 50 in each group admitted in Yenepoya Medical College Hospital, requiring surgeries of short duration were be posted for various short duration surgeries requiring General anesthesia was performed using LMA with spontaneous breathing were and were categorized into two groups standard and rotational insertion techniques and various parameters were compared. Results We found that there was statistically significant difference in the number of attempts between the group-R and the group-S tube with a p value of .001 using the independent samples of t test 2, tailed significance. On evaluation of the age distribution in the study groups, we found that the mean age in the group-R was 33.4 years and the 38.03 years. group-R males made up 46.7 % of the population and females 53.3% and in the group-R males made up 43.3 % of the population and females 56.7%. group-R was 56.7 kgs and the group-R was 55.3kgs the mean weight in the group-R was 162.47cms and the group-R was 160.2cms. There was no statistically significant with a p value of .more than 0.05 using the independent samples of t test 2 tailed significance.We found that there was statistically significant difference in the number of attempts, sore throat hoarseness of voice, incidence of trauma,mucosal tears , the duration that were needed for insertion was lesser in the group-R than the group-S tube with a p value of .001 using the independent samples of t test 2, tailed significance. we found that there was no statistically significant difference in the SPO2, Heart rate and the mean arterial pressure throughout the surgery between the group-R and the group-S tube with a p value of .254 using the independent samples of t test 2, tailed significance. CONCLUSION We concluded that rotational technique technique is practically easy, , needs less effort; consequently it is associated with the least complications .
