Comparison of two methods of LMA insertion,Classic method and using a Laryngoscope.

Comparison of two methods of LMA insertion,Classic method and using a Laryngoscope.

Clinical trial with parallel groups, including two groups by stratified random method and a total of four strata, in each stratum random permutation block method is used. Randomization tool: table of random numbers. Blinding: not used. Sample size: 106 people.

Patients are included in the study based on the inclusion criteria and are divided into two groups of 53 people with stratified random technique. Classes are made based on age group and gender (four classes in total). Within each class, the method of random permutations is used to assign patients to two groups. The randomization tool will be a table of random numbers. In the first group, LMA is implanted in the classical way, in the second group, LMA is implanted using a laryngoscope. In the research, it is done in Ashair hospital of Khorramabad.blinding was not used.

Conditions for entering the study:1.Elective surgery patients in Khorramabad Ashayer Hospital ,in 2023 2.Patients with ASA class 1 and 2. 3.Patients with minor surgery. 4.Patients aged 18 to 65 years 5.Informed patients with written consent Conditions of not entering the study: 1.Patients with head and face injuries and head and neck abnormalities 2.Patients who have contraindications for LMA placement: such as high risk of aspiration, not fasting, pregnancy 3.Patients with difficult Airway

1. Classic method, 2.using a laryngoscope.

comparison of the complications of LMA placement: presence of blood on the LMA, presence of air in the stomach, tooth damage, severity of sore throat( VAS criterion); comparison of LMA insertion time; The number of attempts to successfully insert LMA; level of doctor's satisfaction

Based on consecutive non-probability sampling, based on the order of hospitalization, eligible patients are sampled. In this way, the classes are made based on the age groups and gender of the patient (four classes in total). Within each class, random permutation block method is used to assign to two groups. The random tool will also be a table of random numbers. Due to the nature of the anesthesia technique, it was not used in this research. The initial sample size was 44 people in each group using the variable of pain severity and based on the statistical formula, and finally, taking into account the probability of 20% dropout, the final sample size was 53 people in each group (106 in total).

All data is potentially shareable after de-identifying individuals.
