Comparison of the success rate of intracranial and supraclavicular combined block of the brachial plexus under ultrasound guide compared to single intracclanic and supraclavicular block in arm surgeries

By determining and comparing the combined interscalene and supraclavicular block of the brachial plexus with the interscalene and supraclavicular method alone in arm surgeries, positive steps can be taken in this regard.

Clinical trial with one intervention group and two control groups, double-blind, randomized, phase 3 on 150 patients. Random block allocation with 4 blocks is used for randomization.

The study site at Shahid Beheshti Hospital in Ghoum will be a random selection between patients in need of arm surgery, to be placed in the intervention group (the group to which both nerve blocks are applied) or the control group (which is only one of the Two types of neural blocks are applied to them (random block method of 4 blocks will be used, double-blindness will include the patient himself, the data recorder and the data analyzer.

Inclusion criteria: The patient is over 18 years old, has a broken arm and needs surgery, and has American Stroke Association (ASA) 1, 2; Exclusion criteria: The patient is addicted to drugs, is pregnant, has a history of allergy to local anesthetics, and is not satisfied with the inclusion in this study.

Intervention group 1: For these patients, both interscalene and supraclavicular block methods are used. Intervention group 2: For these patients, only interscalene method is used for arm reticular block. Intervention group 3: For these patients, only the supraclavicular method is used for blocking the neural network.

Reducing the need for painkillers to control postoperative pain.

Randomization using 4 blocks, randomization criterion is done using random block allocation with 4 blocks, which have all four modes (a a b b), (a b a b), (b b a a) and (b a b a) are written on four cards and the four patients are randomly grouped, respectively. The head of the ward takes the patient card out of the bag and the patients are divided into groups by lot. For example, if the lottery is (a a b b), the first and second patients are in the first group, and the third and fourth patients are in the second group, and also for the next four patients, a card is issued again.

The person filling out the questionnaire and the patient will not know the type and method of local anesthetic of the patient. The anesthesiologist will not interfere in the data recording or analysis process.

The data are specific to the present study. There is no further information.
