Comparison Erect Spine in Cardiac Surgery (COESPINE)

Comparison of Two Anesthetic Techniques in Blocking the Erector Plane of the Spine Bilateral in Cardiac Surgery: a Prospective Randomized Double-blinded Clinical Trial

Open cardiac surgeries are characterized by the increased use of opioids and longer extubation times, being post-sternotomy pain one of the causes of greater patient discomfort, plexus blockages have been used more frequently given the good results of anatomical studies and case series that are just beginning to be published. however, there is not enough data to convince the scientific community of its advantages, continuing to carry out its performance due to lack of evidence. Dexamethasone also shows an excellent result blocking the inflammatory chain and it was evidenced that it prolongs the time of blockages when used perineurally in the plexus blockages. This study wants to show the improvement of pain in patients who undergo this type of surgery and also show the advantages of a longer blockage, which can reduce use of analgesic and opioids, as well as decrease the time of hospitalization This is a double-blinded, randomized, clinical trial designed to determine the efficacy of spine erector whit dexamethasone gives more duration of the blockage and less pain after cardiac surgery.

Evaluation of acute pain pos cardiac surgery in patients that who were subjected at myocardial revascularization. We offer Espine erector block (ESP) with linear array Transducer and needle 100mm bilateral as a technique that offer results more hopeful and less invasive in patients with open cardiac surgery. Favoring the implementation of Fastrack anesthesia techniques in cardiac surgery and minimizing complications in this group of patients

Spine erector, Cardiac surgery, Coronary arterial bypass surgery, Acute Pain, Ropivacaine, Dexamethasone

Patients assigned for local anesthetic group will receive a single-shot ultrasound-guided erector spine plane block with 25 mL of 0.2% of ropivacaine

Patients assigned for local anesthetic + steroid group will receive a single-shot ultrasound-guided erector spine block plane with 25 mL of 0.2% of ropivacaine with 5 mg dexamethasone

Changes in Numeric Rating Scale (NRS) and visual analogue scale (VAS) will be recorded daily at postoperative 1 to 7 day or until the patient's hospital discharge if this occurs before 7 days. Numerical rating scales A numerical rating scale (NRS) requires the patient to rate their pain on a defined scale. For example, 0-10 where 0 is no pain and 10 is the worst pain imaginable VAS have also been utilized in EMA research. VAS are measures of subjective or behavioral experience (e.g., pain, physical exercise). They are typically presented as a 10 cm line with descriptive anchors at each end, such as "completed all prescribed activities today" to "completed none of the prescribed activities today." Respondents place a vertical line through the point on the scale that best fits their experience with that construct at that moment.

Changes inThe Brief Pain Inventory (BPI).will be recorded after discharge at 30 days, 60 days and 90 days after surgery *The Brief Pain Inventory (BPI) rapidly assesses the severity of pain and its impact on functioning; BPI Pain Items, Least pain in last 24 hours, Pain on average, Pain right now, Worst pain in last 24 hours; BPI Interference Items, Mood, Walking ability, Normal work (including housework), General activity, Relations with other people, Sleep, Enjoyment of life
