Abstract

Objective: The study aimed to evaluate the analgesic effect of quadratus lumborum block on 175 women after cesarean section at Hanoi Medical University Hospital from November 2024 to January 2025. Study design: Cross-sectional descriptive study. Results: The average age of the women in the study was 29.6 ± 3.6 years. The time to pain relief after 1 minute accounted for the majority with 74.9%; followed by the time to pain relief after 5 minutes accounting for 8.6%; the time to pain relief after 15 minutes accounting for 5.7%; and the lowest was the time to pain relief after 60 minutes accounting for 0.6%. The average duration of effect was 10.2 ± 5.8 (hours). The rate of successful pain relief within the first 6 hours after surgery was 28.6%; 24 hours after surgery was 21.5% and 36 hours after surgery was 33.3%. The level of pain was assessed by VAS scale, showing that 45 people (25.7%) had no pain, 110 people (62.9%) had mild pain, 15 people (8.6%) had moderate pain and 5 people (2.9%) had severe pain, with an average VAS score of 1.8 ± 1.7. Regarding adverse effects, there were 2 cases (1.1%) of nausea and vomiting, 17 cases (9.7%) of itching and hives, 2 cases (1.1%) of local irritation, 3 cases (1.7%) of headache and dizziness, 4 cases (2.3%) of increased body temperature and 1 case (0.6%) of chills. Conclusion: The study showed that the pain relief effect and satisfaction level of parturients with the quadratus lumborum block method in pain relief after cesarean section were relatively good. However, there are still some unwanted side effects that affect the experience of mothers using this method in the future.
