Objective:
The aim of study was to evaluate features for spinal morphine in undergoing coronary artery bypass surgery in early postoperative time and side effects of opioids.
Material And Methods:
Two groups of patients undergoing coronary artery bypass surgery were analyzed. In first group (15 patients) spinal morphine 2 mg and general anesthesia was used, control group (22 patients) - just general anesthesia. Postoperative pain was analyzed with VAS (Visual Analogical Scale). For analgesia, after surgery, was used piritramide via i/v in both groups. Dose of piritramide, extubation time and side effects was analysed after surgery.
Results:
In first group dose of piritramide was 4.5+/-1.1 mg, in control group - 16.5+/-1.1 mg (p<0.05). Extubation time in both groups (354+/-36 min. and 279+/-17 min.) and side effects (nausea and vomiting) was similar.
Conclusion:
Spinal morphine decreased pain after cardiosurgery and don't increased extubation time and side effects of opioids.
