Thoracic Paravertebral Block Versus Rhomboid Block for Postoperative Pain Control in Thoracic Surgeries

Not Applicable
Completed
Conditions
Postoperative Pain
Interventions
Procedure: Rhomboid Block
Procedure: Thoracic Paravertebral Block
Registration Number
NCT05061667
Lead Sponsor
Koç University
Brief Summary

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

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.

GroupInterventionDescription
Group IIRhomboid BlockGroup 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).
Group IThoracic Paravertebral BlockGroup 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).
Primary Outcome Measures
NameTimeMethod
Difference in Visual Analogue Scale (VAS) scores between two groups24 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.

Difference in additional analgesic usage between two groups24 hours

Intravenous patient controlled analgesia usage and additional analgesic dosages will be filed as miligrams or micrograms at 1st, 3rd, 6th, 12th, 24th hours.

Secondary Outcome Measures
NameTimeMethod
Incidence of nausea and vomiting24 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.

Patient satisfaction24 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.
