Accepts healthy volunteers: no
Allocation: RANDOMIZED
Intervention model: PARALLEL
Intervention model description: There are two models for this study. The first group is rhomboid intercostal block group. The second one is no intervention control group
Primary purpose: TREATMENT

Brief summary: Video assisted thoracic surgery (VATS) has recently been evaluated as the standard surgical procedure for lung surgery. Analgesia management is very important for these patients in postoperative period since insufficient analgesia can cause pulmonary complications such as atelectasis, pneumonia and increased oxygen consumption.

Rhomboid intercostal block (RIB) is a novel block and was first described by Elsharkawy et al. It has been reported that RIB may provide effective analgesia management for several surgeries like thoracotomy.

Detailed description: Following Video Assisted Thoracic Surgery Video assisted thoracic surgery (VATS) has recently been evaluated as the standard surgical procedure for lung surgery. The advantages of VATS prodecures compared with open thoracotomy are rapid recovery, short hospital stay and low complication risk. Although VATS is less painful than thoracotomy, patients may feel severe pain during the first hours at postoperative period. Analgesia management is very important for these patients in postoperative period since insufficient analgesia can cause pulmonary complications such as atelectasis, pneumonia and increased oxygen consumption.

Rhomboid intercostal block (RIB) is a novel block and was first described by Elsharkawy et al. Local anesthetic solution is administrated between the rhomboid muscle and intercostal muscles over the T5-6 ribs 2-3 cm medially of the medial border of the scapula. RIB targets both the posterior rami and lateral cutaneous branches of the thoracic nerves and provides analgesia for the hemithorax from T2 to T9. It has been reported that RIB may provide effective analgesia management for several surgeries like thoracotomy.

The aim of this study is to evaluate the efficacy US-guided Rhomboid intercostal block compared to no intervention control group for postoperative analgesia management after VATS. The primary aim is to compare postoperative opioid consumption and the secondary aim is to evaluate postoperative pain scores (VAS), adverse effects related with opioids (allergic reaction, nausea, vomiting) and complications due to block (pneumothorax, hematoma etc).

Eligibility criteria: Inclusion Criteria:

* American Society of Anesthesiologists (ASA) classification I-II
* Scheduled for VATS under general anesthesia

Exclusion Criteria:

* history of bleeding diathesis,
* receiving anticoagulant treatment,
* known local anesthetics and opioid allergy,
* infection of the skin at the site of the needle puncture,
* pregnancy or lactation,
* patients who do not accept the procedure

Primary outcomes:
measure: Opioid consumption
timeFrame: Change from baseline opioid consumption at postoperative 1, 2, 4, 8, 16, 24 and 48 hours
Secondary outcomes:
measure: Pain scores (Visual analogue scores-VAS)
timeFrame: Changes from baseline pain scores at postoperative 1, 2, 4, 8, 16, 24 and 48 hours.
Other outcomes:
Locations:
city: Istanbul
country: Turkey
