Abstract
Background: Cesarean delivery (CD) rates have been increasing annually. For pregnant women, lack of analgesia affects maternal postpartum recovery, as well as breastfeeding and baby development, in addition to increasing the risk of postpartum depression.
Aim: To evaluate, through a literature review, the analgesic effects of intrathecal morphine (ITM) and transversus abdominis plane (TAP) block on DC.
Method: This is an exploratory study, based on the literature review method with evidence synthesis. The database chosen for the selection of papers was PUBMED, using the following search strategy: "intrathecal morphine"[title] AND ("tap block"[title] OR "transversus abdominis plane block"[title]) AND cesarean.
Results: The search occurred in November 2022, and 11 papers that met the search strategy were initially identified. After reading the titles and abstracts, 2 texts were excluded because they were letters to the editor.
Conclusion: The analgesic effects of ITM after DC seem to be superior to TAP blockade, although some studies indicate that both methods are comparable. However, TAP block would be a reasonable alternative when ITM is contraindicated, or even for patients at high risk of postoperative nausea and vomiting, in addition to presenting fewer adverse reactions compared to ITM.
