Summary
Pain is the main obstacle in delaying postoperative recovery and leads to prolonged hospital
stay. Administration of intrathecal morphine during spinal anaesthesia can provide effective
pain control. However, it is associated with significant side effects including nausea,
vomiting and itchiness. Also, it is not suitable in all patients, for example, those with
morphine allergy, or severe respiratory disease. Surgical rectus sheath block involves
injection of local anaesthetic agents into the rectus sheath space before closure of the
wound. It has been shown to provide adequate pain control with less systemic side effects.
The aim of the study is to evaluate the effectiveness of surgical rectus sheath block and
intrathecal morphine in post-Caesarean section pain control.
