Detailed 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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Group I
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).
Procedure: Thoracic Paravertebral Block

Other Names:
  • TPVB
Experimental: Group II
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).
Procedure: Rhomboid Block

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Difference in Visual Analogue Scale (VAS) scores between two groups
Time Frame: 24 hours
Statistically significant difference in VAS scores at 1st, 3rd, 6th, 12th, 24th hours between two groups. On a scale of 0 to 10, where 0 means no pain and 10 means the worst imaginable pain.
24 hours
Difference in additional analgesic usage between two groups
Time Frame: 24 hours
Intravenous patient controlled analgesia usage and additional analgesic dosages will be filed as miligrams or micrograms at 1st, 3rd, 6th, 12th, 24th hours.
24 hours

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Incidence of nausea and vomiting
Time Frame: 24 hours
Incidence of symptoms like nausea and vomiting will be filed at 1st, 3rd, 6th, 12th, 24th hours. On a scale of 0 to 1, where 0 means no symptoms and 1 means nausea and vomiting.
24 hours
Patient satisfaction
Time Frame: 24 hours
Patient will be reevaluated at 24th hour for analgesic satisfaction. On a scale of 0 to 3, where 0 means not satisfied and 3 means satisfied.
24 hours
