About

The main aim of this study is to compare thoracic paravertebral block and rhomboid block for postoperative analgesia and analgesic usage in thoracic surgeries.

Full description

Patients with scheduled thoracic surgery are going to be enrolled for this study. Patients will be randomized and separated in two groups. Group I will receive thoracic paravertebral block, group II will receive rhomboid block. Each group will receive patient controlled analgesia with intravenous fentanyl. Patients will be monitored at postoperative 1st, 3rd, 6th, 12th, 24th hours and their VAS scores, adverse reactions like nausea and vomiting, total analgesic usage, additional analgesic need and time of the first report of pain will be filed. Then the two groups will be compared and evaluated.

88 participants in 2 patient groups

Group I

Active Comparator group

Description:

Group I will consist of randomly assigned patients scheduled for thoracic surgery. These patients will recieve paravertebral block which is already proven to be effective in postoperative pain. After applying standart monitors to the patient and proper positioning in the operating room, paravertebral block will be performed at the planned surgical side using high frequency (8-18 MHz) linear probe of GE Logiq S7 (General Electric Healthcare, Little Chalfont, United Kingdom). 20 ml of 0.25% bupivacaine will be administered into the paravertebral space at T5-T6 vertebra levels using a 50 mm 22 G block needle (BBraun, Melsungen, Germany).

Treatment:

Procedure: Thoracic Paravertebral Block

Group II

Experimental group

Description:

Group II will consist of randomly assigned patients scheduled for thoracic surgery. These patients will recieve rhomboid block which is being experimented for its efficacy in postoperative pain. After applying standart monitors to the patient and proper positioning in the operating room, rhomboid block will be performed at the planned surgical side using high frequency (8-18 MHz) linear probe of GE Logiq S7 (General Electric Healthcare, Little Chalfont, United Kingdom). 20 ml of 0.25% bupivacaine will be administered into the plane between rhomboid muscle and intercostal muscles, medial to scapula at T5-T6 vertebra levels using a 50 mm 22 G block needle (BBraun, Melsungen, Germany).

Treatment:

Procedure: Rhomboid Block
