- Brief Summary
Opioids used in attenuation of the neuroendocrine stress response in patients undergoing off-pump coronary artery bypass graft (OPCAB) it produces predictable satisfactory analgesia and sedation but with side effects such as respiratory depression, drowsiness, and myocardial depression. Regional techniques may be encouraged to be anti-stress procedures and produce risk-free postoperative (OPCAB) period. Pectoralis nerve block (pecs block) appears to possess a great deal of promise for patients undergoing (OPCAB) because of low complication rates as it is less invasive regional analgesic technique when compared to paravertebral, thoracic epidural analgesia and parenteral analgesia.
- Detailed Description
Aims: Ultrasound Guided Bilateral Pecs block would provide attenuation of the neuroendocrine stress response with hemodynamic profile stability, decreased analgesic consumption and improves patient postoperative outcomes after(OPCAB).
Materials and Methods: A prospective, single-blind, controlled study enrolled forty patients between the age groups of 25 and 65 years undergoing (OPCAB) through midline sternotomy under general anesthesia and randomly allocated into two groups with 20 in each group. Group 1 patients did not receive Pecs block (control group), patients were anesthetized to keep the heart rate and blood pressure within 25% of the baseline values. Whereas Group 2 patients received bilateral Pecs block preoperatively. Patients were extubated once they fulfilled extubation criteria. Heart rate, mean arterial blood pressure, Plasma levels of adrenocorticotropic hormone(ACTH) and cortisol, sufentanil consumption were determined at the following points: Basically (T0),immediately before the induction of anesthesia; (T1), immediately after tracheal intubation; (T2),immediately after sternotomy;( T3), 30 minutes after the start of surgery; and (T4), at the end of surgery. Ventilator duration, duration of ICU stay hospital stay were recorded postoperatively.

Basically (T0),immediately before the induction of anesthesia; (T1), immediately after tracheal intubation; (T2),immediately after sternotomy;( T3), 30 minutes after the start of surgery; and (T4),immediately at the end of surgery Ranges of Cardiac indices will be estimated as follow :CO in (L/min),Cl in (L/min/m2),SVR in (dyn•s/cm5) and PVR in (dyn•s/cm5).
changes in Plasma levels of cortisol hormone Basically (T0),immediately before the induction of anesthesia; (T1), immediately after tracheal intubation; (T2),immediately after sternotomy;( T3), 30 minutes after the start of surgery; and (T4), immediately at the end of surgery Ranges in Plasma levels of cortisol in (ng/mL)
Changes in Heart rate. Basically (T0),immediately before the induction of anesthesia; (T1), immediately after tracheal intubation; (T2),immediately after sternotomy;( T3), 30 minutes after the start of surgery; and (T4), immediately at the end of surgery Ranges of heart rate will be estimated in beat per minutes.
changes in Plasma levels of adrenocorticotropic hormone(ACTH) . Basically (T0),immediately before the induction of anesthesia; (T1), immediately after tracheal intubation; (T2),immediately after sternotomy;( T3), 30 minutes after the start of surgery; and (T4),immediately at the end of surgery Ranges in Plasma levels of adrenocorticotropic hormone(ACTH) in (pg/mL) and cortiso in l(ng/mL)
