Comparison Of The Effect Of Using A Bupivacaine 0.5 % Plus Normal Saline With A Bupivacaine 0.5 % Plus Dexamethasone On Post -surgery Pain With Infraorbital Block Technique In FESS (Functional Endoscopic Sinus Surgery)
Comparison of the Effects of Using Bupivacaine 0.5% Plus Normal Saline with a 0.5% Bupivacaine Plus Dexamethasone Against Postoperative Pain in Infraorbital Block Techniques in FESS Surgery
Introduction
In the field of anesthesia, the use of vasoconstrictors plays a crucial role in reducing the size of blood vessels, which in turn can reduce the amount of local anesthesia that is absorbed into blood circulation. The use of adjuvants, such as dexamethasone, in peripheral nerve blockade has the potential to increase the effectiveness of local anesthesia. However, the use of adjuvants also causes pros and cons that need to be considered. The purpose of this study is to assess the difference in effect between the use of 0.5% bupivacaine coupled with normal saline and the use of 0.5% bupivacaine coupled with dexamethasone to postoperative pain levels in patients undergoing functional endoscopic sinus surgery (FESS) surgery with infraorbital block technique.
The use of local anesthesia in surgical procedures has become a common practice to reduce postoperative pain. However, the effectiveness of local anesthesia can be influenced by various factors, including the type of anesthetic used, the dosage, and the technique of administration. In this study, we aimed to investigate the effect of using bupivacaine 0.5% plus normal saline versus bupivacaine 0.5% plus dexamethasone on postoperative pain in patients undergoing FESS surgery with infraorbital block technique.
Research Methods
This study was conducted using a double-blind randomized controlled trial design at the Mina Medan Hajj General Hospital, between August and October 2018. As many as 40 patients were selected through the non-probability sampling method with the Consecutive Sampling approach. Before the extubation process, an infraorbital block was carried out with a transnal technique using a 0.5% bupivacaine technique in a dose of 1-1.5 mg/kg (maximum 100 mg) mixed with normal saline for group A, and bupivacaine 0.5% plus Dexamethasone (0.1 mg/kg) for group B. After undergoing FESS surgery, the patient was considered to use a visual analog scale (VAS) pain scale with a score of 0-10 and an additional analgesic requirement in the first 24 hours.
Research Result
Of the 40 samples examined, there were 20 male patients (50%) and 20 female patients (50%). Pain assessment in time T0 to T3 shows that there are no statistically significant differences (P> 0.05) between the two groups. However, group B (receiving Bupivacaine + Dexamethasone) shows a lower VAS value compared to group A (Bupivacaine + Normal Saline).
Although the results of statistical testing show that pain differences in all examination time are not significant, this information still provides insight into the relative effectiveness of the two anesthetic combinations in the context of postoperative pain. The use of dexamethasone as an adjuvant in peripheral nerve blockade has been shown to have a potential effect on reducing postoperative pain. However, the results of this study suggest that the addition of dexamethasone does not have a significant impact on reducing pain level after surgery in the context of this study.
Conclusion
From this study, it can be concluded that there is no statistically significant difference between the VAS value in the group that gets a 0.5% bupivacaine plus normal saline and the group that gets a 0.5% bupivacaine plus Dexamethasone. This shows that the addition of Dexamethasone as adjuvant does not have a significant impact on reducing pain level after surgery in the context of this study.
Further analysis needs to be done to determine whether other factors, such as the time of administration of anesthesia, dosage, or patient variable, can affect more significant results. In-depth research on the use of adjuvants in peripheral nerve blockade is expected to make a greater contribution in postoperative pain management.
Limitations of the Study
This study has several limitations that need to be considered. Firstly, the sample size was relatively small, which may not be representative of the larger population. Secondly, the study was conducted in a single hospital, which may not be generalizable to other settings. Finally, the study only investigated the effect of bupivacaine 0.5% plus normal saline versus bupivacaine 0.5% plus dexamethasone on postoperative pain, and did not investigate the effect of other anesthetic combinations.
Future Directions
Future studies should aim to investigate the effect of other anesthetic combinations on postoperative pain, including the use of different types of local anesthetics, adjuvants, and techniques of administration. Additionally, studies should aim to investigate the effect of other factors, such as the time of administration of anesthesia, dosage, and patient variable, on postoperative pain.
