Comparison of the results of wound washing and repair using tap water compared to sterile normal saline in soft tissue lacerations in patients

Determining the consequences of washing and wound healing using tap water compared to sterile normal saline in soft tissue tears in Patients referred to the hospital's emergency room

The clinical trial has a control group, with parallel groups, without blinding, randomized by block method on 240 patients

The study is conducted in the emergency department of Madani Karaj Hospital. People with soft tissue tears meet the entry criteria and according to the Suture procedure, before repair, the wound is washed with tap water or normal saline. Using tap water with a gavage syringe, a sterile receiver, and a volume equal to normal saline serum (half a liter per 10 cm).The study is open label.

Patients referred to emergency room, Karaj Madani Hospital, over 18 years of age, with no history of taking antibiotics and immunosuppressive drugs, are included in the study؛ and if the exclusion criteria include: People who have cardiovascular diseases such as varicose veins and DVT at the beginning of the study and have blood supply disorders؛ People who have any underlying disease that weakens the immune system (for example, diabetes mellitus, chronic alcoholism, asplenism, primary immune disorder, use of steroids or chemotherapy) ؛People who are currently or recently taking antibiotics. have had biotics؛ Chronic wounds such as bedsores or diabetic foot ulcers and vascular and varicose wounds؛ Punctured or bitten wounds؛ Tendon ruptures or bone fractures؛ Wounds that have been created for more than 6 hours

In the intervention group, wound washing for the suture procedure is done with tap water and in the control group with sterile normal saline.

Age؛ sex؛ wound site infection؛ wound healing time؛ wound length

The block randomization method will be used for randomization. The length of the block for each of the treatment groups is considered to be 4, that is, each block will include two people from the intervention group and two people from the comparison group. If the people of the group Indicate the intervention with the letter A and the people of the comparison group with the letter B. In this case, according to the formula . then for Each of these blocks will generate random codes. Then one of these blocks will be randomly selected and based on the sequence of letters A and B in the selected block, eligible people will be assigned to treatment or comparison groups. This random process of selecting blocks and assigning people to intervention and comparison groups It will continue until reaching the desired sample size This method solves the problem of imbalance that can occur in simple randomization.
