The incidence of chronic post-surgical pain (CPSP) after caesarean section (CS) is reported to be as high as 18%, reflecting it to be a significant clinical problem. Studies related to prevention of progression of acute post-CS pain to its chronicity are sparse. Current guidelines on post-CS analgesia recommend the use of intrathecal (IT) opioids to spinal anaesthesia for improved post-CS pain relief. Despite its frequent use, studies related to the IT morphine use and its association with post-CS chronic pain are lacking. A recent prospective observation study revealed a significant reduction in persistent pain after CS when IT morphine was used as an adjuvant to spinal anaesthesia. However, there is no any randomized controlled trial (RCT) that has explored this association to date. We hypothesized that spinal morphine would reduce the incidence of persistent pain after CS.

Primary | Number of participants with the incidence of post surgery chronic pain at 3 months following elective caesarean section | To find the number of participants with the incidence of post surgery chronic pain at 3 months following elective caesarean section in those receiving Intrathecal morphine and normal saline | 3 months after elective caesarean section | |
Secondary | Number of participants with the incidence of post surgery chronic pain at 6 months following elective caesarean section | To find the number of participants with the incidence of post surgery chronic pain at 6 months following elective caesarean section in those receiving Intrathecal morphine and normal saline | 6 month after elective caesarean section | |
Secondary | Brief pain inventory (BPI) pain severity scores at 3 and 6 month after elective caesarean section between those receiving intrathecal morphine and normal saline | Short form Brief pain inventory (BPI) pain severity scores: Pain is rated on a 0 to 10 numerical rating scale, with 0="no pain" or and 10=pain "as bad as you can imagine." Participants rate their worst, least, and average pain over the last seven days, as well as their pain right now. | 3 and 6 months after elective caesarean section | |
Secondary | Brief Pain Inventory (BPI) pain interference scores at 3 and 6 month after elective caesarean section between those receiving intrathecal morphine and normal saline | Short form Brief pain inventory (BPI) pain interference scores: Participants rate how much pain interfered with various daily activities, including general activity, walking, work, mood, enjoyment of life, relations with others, and sleep. The interference items is presented with 0-10 scales, with 0=no interference and 10=interferes completely. | 3 and 6 months after elective caesarean section | |
Secondary | Any pain medication or treatment received for relieving pain. If so, the amount of pain relieved. | Currently use of pain medications, its dosages or any other treatment will be recorded.In the last 24 hours, how much relief have pain treatment or medications provided. Please rate in 0-100% where 0% is no relief, 100% complete relief. | 3 and 6 months after elective caesarean section | |
Secondary | Numerical rating Scale (NRS) pain scores and opioid consumption post operatively | Post operative pain intensity will be assessed using Numerical rating scale(NRS), where 0="no pain" or and 10=pain "as bad as you can imagine." Total opioid consumption will be calculated as total morphine or equivalent in mg. | 24 and 48 hrs after surgery |
