Brief summary

Thoracotomy is recognized as one of the most painful surgical procedures. This increases the frequency of postoperative pulmonary complications. Erector Spinae Plane Block (ESPB) and Serratus Anterior Plane Block (SAPB) are more superficial, easier to perform, and less likely to have complications. In addition, ESPB and SAPB applications are increasing in patients who underwent thoracotomy and thoracoscopic surgery. In this study, the investigators aimed to evaluate the effect of continuous ESPB and continuous SAPB via US-guidance on post-thoracotomy pain.

Design outcomes

Primary

Measure	Time frame	Description
Pain scores	72 hours after surgery	Pain will be assessed at rest and while coughing using the visual analog scale on a scale from 0 (no pain) to 10 (worst pain). Pain assessment will be done at 1st, 2nd, 4th, 8th, 16th, 24th, 48th and 72nd hours after surgery.

Secondary

Measure	Time frame	Description
Morphine consumption	24 hours after surgery	Morphine consumption for 24 hours will be recorded
Side effects	72 hours after surgery	Side effects, such as allergy to local anesthetics, hypotension, nausea/vomiting, itching, headache, and sweating will be recorded.
