Effect of Incisional Injection of Bupivacaine for Pain Control after Pediatric Lower Abdominal Surgery

Abstract

Postoperative pain control in children is very important because poor control of pain in this group leads to increased mortality and morbidity. Local anesthetic injection for pain management with multimodal analgesia has recently been reported as an effective method for postoperative pain control. Local anesthetic injection is an analgesic technique that has been well received and has been considered as a safe and effective way to reduce postoperative pain. Therefore, we determined that the effect of incisional injection of reducing the severity and incidence of post-surgical pain Study of children's actions. Materials and Methods: A total of 72 children with Class I and II ASA grading at the age of 1-12 years who underwent lower abdominal surgery who were referred to Tabriz Children's Hospital were randomly divided into two groups: intra-incisional injection and control group. In case group, after the completion of the surgery,1 ml / kg of bupivacaine0 /125% to a maximum of 20 ml is injected into the fascia layer, and the control group is not injected. After surgery, pain is measured based on VAS (visual analog scale) scores at specific intervals, as well as the first request for analgesia, the total dose of analgesic drugs after surgery, and the severity of the postoperative complications in two groups was registered. Results: The results of descriptive statistics and mean comparative tests showed that the two groups of patients in terms of age (p = 0.6), weight (0.8 p =), height (0.5 p =), gender ratio in two groups (0.1 P = 0.05), duration of anesthesia (0.1 p =), duration of operation (p = 0.38), diastolic pressure (0.1 p =), systolic pressure (p = 0.09) and heart rate (0.7 p =) were not significant. The pain and the total dose of pain medication were statisticaly significant between the two groups (p <0.001). Also, the difference between mean heart rate variables, systolic pressure and diastolic pressure, pain intensity, and total pain dose in 9 postoperative times were significant in both groups (p <0.001). The study of the difference between the first request for postoperative analgesia in the two groups showed that after 12 hours, the relationship between the analgesic demand and the case group was not statistically significant.
