Efficacy of Pericapsular Nerve Group Block in the Prevention of Postoperative Pain in Shoulder Surgery

Dear Patient, You have been scheduled for shoulder surgery by your surgeon. This surgery is performed under general anesthesia, that is, by putting the patient to sleep, and then moderate or severe pain is experienced. In order to prevent this pain to be experienced, analgesics are given through the vascular access or the operated area, namely the shoulder, is locally anesthetized. Different techniques are used to numb the shoulder locally. One of these techniques is pericapsular nerve group block. In this block, some of the nerves that carry the pain sensation of the shoulder are temporarily anesthetized with local anesthetics. Thus, it is aimed to reduce post-operative pain.

In this study, we plan to investigate how effective the pericapsular nerve group block is on postoperative pain. In this scientific study, patients will be randomly divided into two groups. Pericapsular nerve group block will be applied to one group of patients, while the other group will not be blocked. Pain medication will be administered intravenously to both groups before waking them up, and at the same time, a device called 'Patient Controlled Analgesia' (PCA) containing a very strong pain medication will be inserted in all patients in the service.

This device; It is a device that contains analgesics and gives analgesics to the patient through the vascular access according to the patient's request, and it works with the help of a button on it. When the patient feels pain, he will press the button and the device will give the medicine to the patient in a predetermined dose and time. The device records the total amount of pain medication sent in 24 hours on its screen. The amount of medication delivered by this device will be compared between patients with and without block. Thus, the effect of pericapsular nerve group block on postoperative pain will be investigated.

What are the procedures to be applied in the research? The surgery that will be applied to you is performed under general anesthesia. Pericapsular nerve group block, which is one of the pain relief methods we apply for shoulder surgery; It involves administering a local anesthetic drug with the help of a needle between the muscles in the shoulder and numbing your shoulder area.

After the blocking procedure, painful stimulus will be given and it will be checked whether you have pain and loss of sensation and what it is worth. If there is loss of feeling, the block will be considered successful.
