Background
Major abdominal surgeries induce neurohumoral changes responsible for postoperative pain, various organ dysfunctions and prolonged hospitalization. Inadequate pain control is harmful and costly to patients thus an appropriate pain therapy to those patients must be applicated.
Methods
One hundred patients (ASA I or II) of either sex aged from 20 to 60 years were scheduled for elective major abdominal surgery. Patients were allocated randomly into two groups (fifty patients each) to receive: patient-controlled epidural analgesia with bupivacaine 0.125% and fentanyl (PCEA group), or patient controlled intravenous analgesia with fentanyl (PCIA group). Postoperative pain was assessed over 24 h using Numerical Pain Rating scale (NPRS). The frequency of rescue analgesia, sedation score and overall patient satisfaction were recorded. Any concomitant events like nausea; vomiting, shivering, pruritus or respiratory complications were recorded postoperatively.
Results
There was a significant less pain in PCEA group at 2, 8 and 12 h. postoperative but PCIA group had less pain at immediate postoperative time. As regard sedation scale, patients of the PCEA group were significantly less sedated than PCIA group at immediate postoperative only. Overall patient satisfaction was significantly more in PCEA group.
Conclusion
This study concluded that both PCEA and PCIA were effective in pain relief after major abdominal surgery but PCEA was much better in pain relief, less sedating effect and overall patient satisfaction.
