Comparison of the effect of closing two tourniquets versus closing one tourniquet on the success of access to a peripheral venous line in emergency department patients

Comparison of the success rate of closing two tourniquets and one tourniquet in peripheral venous line access in patients of the emergency department of Vasi Hospital in Sabzevar city.

Clinical trial with a control group, with parallel groups, double-blind,There is not blinding , phase 3 on 100 patients, randomization load using permutation blocks

After the approval of the project and obtaining the code of ethics and IRCT, we referred to the emergency department of Vasei Hospital in Sabzevar and selected the patients who referred to the emergency department and met the study inclusion criteria using the convenience method. The written informed consent of patients was obtained. Then, the patient's demographic information questionnaire and clinical trial application checklist were completed.

Inclusion Criteria: 1. The need to establish a venous line, 2. Having consent to participate in the study, 3. The age of the studied patients is limited to 20-50 years 4. Pregnancy (other than absence, patients are considered high risk group) Exclusion criteria: having a life-threatening condition (emergency), edema, obesity, peripheral vascular disease, Raynaud's phenomenon, scleroderma, sickle cell anemia, methemoglobinemia, patients with a history of any drug allergy and underlying diseases, including cardiovascular , high blood pressure, coagulation disorder, excessive bleeding, Hb less than 10, kidney failure, drug abuse and skin infection, and patients are less than 20 years old and more than 50 years old.

Intervention group: 50 patients with two tourniquets Control group: 50 patients with a tourniquet

success in accessing the peripheral venous line

Using the permuted block technique, the patients were divided into two groups of one tourniquet and two tourniquets. In this way, each block of n=4 was allocated to the intervention group of n=2 and the control group of n=2. A total of six blocks in different states were obtained and each block was numbered with a number. The blocks of n=4 were selected based on the table of random numbers until the sample size reached n=100. Finally, 50 patients were in the control group and 50 patients were in the intervention group. This was repeated until the end of sampling. In allocation concealment technique, the participants themselves were not aware of the type of educational intervention and the data analyst was not aware of the group due to the coding of the data. To avoid bias, sampling was done by an officially employed male nurse with at least two years of clinical work experience.
