Summary
Intraspinal narcotic anesthesia using morphine or meperidine in open heart surgery patients showed good pain control and respiratory management. While mild side effects like itching and headache occurred, they were acceptable and not clinically significant.
Area of Science:
- Anesthesiology
- Cardiovascular Surgery
Background:
- Intraspinal narcotic anesthesia offers an alternative anesthetic approach.
- Opioid analgesics are commonly used for pain management in surgical settings.
Purpose of the Study:
- To evaluate the efficacy and safety of intraspinal narcotic anesthesia in open heart surgery patients.
- To compare the effects of morphine and meperidine administered intraspinally.
Main Methods:
- 180 open heart surgery patients received intraspinal anesthesia.
- Morphine (0.1 mg/Kg) or meperidine (1.5 mg/Kg) was administered via the barbotage technique.
- Patients were divided into groups receiving morphine, meperidine, or a combination.
Main Results:
- No significant cardiovascular complications were observed.
- Respiratory depression was noted as a serious issue primarily with morphine.
- Mild complications included pruritus (11.1%), voiding difficulty (10.6%), intraoperative awareness (4.4%), and spinal headache.
Conclusions:
- Intraspinal narcotic anesthesia provided excellent postoperative analgesia and respiratory control.
- Despite mild, acceptable side effects, the technique is a viable option for open heart surgery.
- Morphine administration was associated with a higher incidence of respiratory depression.
