Pain after caesarean section should be addressed so that patients feel comfortable and can be mobilized immediately. There are two classes of analgesics that can be used to reduce pain, namely class of opioids and nonsteroidal antiinflamation drug (NSAID). One class of opioids frequently used is fentanyl, whereas the NSAID class using ketorolac. Fentanyl is an opioid analgesic which are lipophilic, so it has several advantages compared to morphine. Ketorolac began to be widely used as an analgesic because of the nature of strong analgesic. This study was compare the use of multimodal analgesia techniques using a continuous intravenous fentanyl-ketorolac and ketorolac bolus intermittent. Subjects consisted of 40 post cesarean section were divided into 2 groups. Group multimodal were 20 people with a multimodal analgesic continuous use, and 20 people with intermittent single drug ketorolac as ketorolac group. Giving analgesics began shortly after the surgery is completed. Both groups were then seen when started to feel pain using a visual analog scale (VAS), and the addition of analgesics if necessary. Results showed 18 patients (90%) with multimodal analgesia had no pain since the completion of the operation up to 24 hours postoperatively (VAS 0-3), 2 patients (10%) need additional bolus intravenous ketorolac at 10 hours postoperatively (VAS 5). A total of 20 patients (100%) with ketorolac group requires 2 times ketorolac injection during 24 hours postoperatively. This study showed that multimodal analgesia technique using fentanyl-ketorolac is superior in reducing post cesarean section pain compared with single drug ketorolac.
