About

In this study our aim is to investigate the effects of ultrasound (USG) guided pectoral block (PECS) type 1 in the administration of an implanted port-a-cath .

Full description

Cancer is one of the most important reasons of mortality in the world. There are a lot of different types of treatments for cancer and so far chemotherapy is the most common one. However, chemotherapy damages the peripheral veins, so implanted subcutaneous port-a-caths are used as an alternative. Traditionally this implantation is adminstered with infiltrative anesthesia. Recently, USG is used in anesthesia practice world wide. Blanco R et all (1) defined PECS 1 block as an alternative to paravertebral block. PECS 1 block aims to anesthetize the medial and lateral pectoral nerves. In this study our aim is to investigate the effects of USG guided PECS 1 block in the administiration of an implanted port-a-cath .

PECS 1 Block

Experimental group

Description:

40 patients who had PECS 1 block for peroperative analgesia in port-a-cath replacement. All patients will receive IV Midazolam (0.05mg/kg) premedication. Standard monitorization of EKG, non- invasive blood pressure and pulseoximeter will be done and recorded in every 5 minutes. After sedation and standard monitorization, 20 minutes before the intervention and in the supine positon the PECS 1 block will be done. 10 % povidone - iodin will be used for sterilization and the USG probe will be covered with sterile sheath. The block will be done as a single injection of local anaesthetic between pectoralis major and pectoralis minor muscles at the level of the 3rd rib to anaesthetise the lateral and medial pectoral nerves. The USG probe will be replaced inferior to the clavicle. Identify the pectoralis muscles with the axillary artery and axillary vein on sonography. The brachial plexus should be visible underneath. After confirmation with 20 mL %0.25 bupivacaine will be administered.
