About this study

Official title: Investigation of the Effect of Serratus Anterior Plan Block on Postoperative Pain in Patients Who Underwent Minimally Invasive Cardiac Surgery.

Acute postoperative pain is defined as sudden onset pain that develops after stimulation due to surgical intervention. It is most severe in the first 24 hours after surgery and gradually decreases in severity and creates dissatisfaction in the patient. Postoperative pain that cannot be treated properly can cause various systemic effects, prolongation of hospital stay, decrease in patients' quality of life, and development of chronic pain. An increase in blood pressure, heart rate, cardiac irritability and systemic vascular resistance is observed with the sympathetic response due to pain. Increased myocardial workload and oxygen consumption may increase or trigger myocardial ischemia. Pulmonary dysfunction has an important place in the determination of mortality and morbidity after surgery and anesthesia.Especially in patients who have undergone thoracic surgery, pain limits the movements of the thoracic muscles, reducing functional residual capacity and vital capacity.This causes the development of atelectasis in the patient and the development of hypoxia and pneumonia due to the deterioration of the ventilation/perfusion ratio. Effective analgesia can be achieved in the postoperative period by administering a certain volume of local anesthetic between any two muscle planes using USG. In SAPB, a local anesthetic is injected between the serratus anterior muscle and the latissimus dorsi muscle to create sensory paresthesia in the thoracic wall. It is known to reduce pain scores in the postoperative period.

Serratus anterior plane block is a safe facial plane block performed under USG guidance.Depending on the application site of the block and the amount of local anesthetic administered, different numbers of intercostal nerves, long thoracic nerves and thoracodorsal nerves may be affected. The fact that Serratus anterior plane block (SAPB) is effective between T2-T9 dermatomes enables it to be used effectively in lateral thoracic wall surgeries.

Read the detailed description

Patients between the ages of 18-65 who will undergo minimally invasive cardiac surgery under elective conditions will be included in the study.

Patients will be randomized. The patients will be included in the study after they are informed about the study and their consent is obtained with the patient consent form. Patient groups will be divided into two groups as SAPB Group (n=20) and Control Group (n=20). All patients will be intubated with a double lumen endotracheal intubation tube in accordance with general anesthesia rules. Patients' age, weight, height, body mass index (BMI), additional disease, surgery, medications used, Ejection/Fraction, platelet count (x10/L), cardiopulmonary bypass time (min), aortic cross clamp time (min) , intraoperative remifentanil amount (mcq), intraoperative morphine dose (0.1 mg/kg), postoperative extubation time (min), post extubation, 1. hour, 2nd hour, 4th hour, 8th hour, 12th hour, 24th hour NRS (Numerical Rating Scale) pain score (between 0 and 10, no pain at 0, maximum pain at 10), extubation after, 1st hour, 2nd hour, 4th hour, 8th hour, 12th hour, 24th hour morphine consumption (Patient Controlled Analgesia), how many additional doses paracetamol was administered, how many additional doses were administered, additional analgesic need time (minutes), postoperative hemodynamic monitoring, 1st hour, 2nd hour, 4th hour, 8th hour, 12th hour, 24th hour PH, PO2 (oxygen pressure) ), MAP (mean arterial pressure), will be recorded. In addition, nausea, vomiting, itching, constipation, and the duration of intensive care hospitalization will also be recorded in the postoperative period. The patient will be told to express the degree of postoperative pain using the numerical scoring scale (NRS) before the operation. The patient will be informed about the PCA to be inserted in the postoperative period. After the surgical procedure is completed, serratus anterior plane block will be applied to the patients under the guidance of postoperative USG. After the surgery, the patients will be transferred to the cardiovascular surgery intensive care unit.

Serratus Anterior Plan (SAP) Block:

After the operation is completed, the block operation will be performed while intubated. The patient will be in the supine position.

The area where the procedure will be performed will be cleaned with povidone iodine. With a high frequency (10-18 MHz) ultrasound linear probe covered with a sterile sheath, using the 'in plane' technique using a 22-gauge, 80 mm insulated Quincke type needle, midaxillary line with the latissimus dorsi muscle and serratus at the level of the 4th and 5th ribs. After determining the fascia between the two muscles by imaging the muscle, the block needle will be advanced from caudal to cranial and 40 ml of 0.25% bupivacaine will be injected on the serratus muscle between the two muscles. No block will be applied to the control group. Only the PCA (Patient Control Analgesia) drug with Morphine will be used.

In the intensive care unit, the patients will be extubated after respiratory effort appears, when the patient is awake, blood gas values are within the normal range, body temperature is normal, and hemodynamically stable. When NRS is >3-4, patients will be instructed to press the PCA device. If the patient's consciousness and hemodynamic status do not allow for pain assessment, the patient will be excluded from the study.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • SAPB (Serratus Anterior Plan) BlockProcedure or surgery

    The patient will be in the supine position. The area where the procedure will be performed will be cleaned with povidone iodine. Using a 22-gauge, 80 mm insulated Quincke needle with a high frequency (10-18 MHz) ultrasound linear probe covered with a sterile sheath, the latissimus dorsi muscle and the serratus muscle will be visualized at the level of the 4th and 5th ribs. After determining the fascia between the two muscles, the block needle will be advanced from caudal to cranial and 40 ml of 0.25% bupivacaine (local anesthetic) will be injected on the serratus muscle between the two muscles.
