IRCT20221115056503N1 IRCT 2023-02-01 Birjand University of Medical Sciences Comparison of hemodynamic changes in the use of two methods of trapezius compression and mandibular lifting to determine the right time to insert a laryngeal mask in patients under general anesthesia with sodium thiopental Comparison of hemodynamic changes in the use of two methods of trapezius compression and mandibular lifting to determine the right time to insert a laryngeal mask in patients under general anesthesia with sodium thiopental 2022-11-22 anticipated 138 Complete https://irct.ir/trial/66896 interventional Randomization: Randomized, Blinding: Single blinded, Placebo: Not used, Assignment: Parallel, Purpose: Supportive, Randomization description: After determining the eligible people to enter the study for random assignment between two groups (group A: squeezing the trapezius muscle and group B: raising the lower jaw), a random block method with concealment will be used. There are four (AABB, BBAA, ABAB, BABA, ABBA, BAAB) and each block will be randomly selected. RANDBETWEEN command (random selection with repetition) was used in Excel software to generate a random sequence (selection of blocks). Closed opaque envelopes will be used for concealment, Blinding description: Patients do not know how to be placed in groups. N/A Candidates for surgery under general anesthesia. Intervention 1: 1- Pulling the lower jaw up (common method): placing the fingers in the angle of the mandible on both sides and pulling the lower jaw upwards and checking the patient's movement response. Intervention 2: Intervention group2: Squeezing the trapezius muscle on both sides at a distance of two to three centimeters from the root of the neck between the first and second fingers of the hand and examining the patient's motor response. No - There is not a plan to make this available Justification or reason for not sharing IPD is There is no need to share non-identifiable personal data of the participants, and there is no scientific justification for publishing this data
