Abstract

Introduction: The popularity of the transdermal buprenorphine patch (TDB) is currently increasing for chronic pain management because of its ease of use, non-invasive nature, sustained drug delivery, and avoidance of side effects associated with oral or parenteral routes. However, its role in postoperative pain management for aortofemoral bypass surgery is poorly established. The study was designed to compare the postoperative analgesic effect of intravenous tramadol versus transdermal buprenorphine patch in patients undergoing aortofemoral graft surgery. Objective: To compare the efficacy between a buprenorphine patch versus intravenous tramadol for postoperative analgesia in patients undergoing aortofemoral bypass surgeries.  Methods: This is a hospital-based, prospective, randomized, and interventional study. This study was conducted in the cardiac surgery Operation Theatre (OT). A total of 60 patients of either sex belonging to ASA 2 or 3 in the age group of 30-60 years and BMI ≤ 40 kg/m2 scheduled for aortofemoral bypass surgery were enrolled in this study. These 60 patients were divided into two groups; the intravenous tramadol and the transdermal buprenorphine patch group using a randomization table. Results: The two groups were comparable in terms of demographical data, duration of surgery, and time for extubation. The analysis of variance showed that the VAS score was higher in the buprenorphine group as compared to the tramadol group for the first 3 hours post operatively but after that, the VAS score was significantly less in the buprenorphine group at various study intervals. A greater number of patients complained of pain for the first 3 hours postoperatively, but after that the patients had better pain relief for the rest of the study period. Conclusion: Transdermal buprenorphine applied preoperatively is a safe and effective option for postoperative pain management as it offers superior pain control and reduces the need for rescue analgesia, thereby decreasing potential side effects as compared to intravenous tramadol.

Abstract

The purpose of this research is to assess a continuous stirred-tank reactor (CSTR) system's performance. To enhance its performance, a fractional-order proportional-integral-derivative (FOPID) controller was employed, necessitating the tuning of independent control parameters. For this purpose, a sine-cosine algorithm (SCA) was introduced to optimize these parameters. The FOPID controller, tuned using the SCA, provides a powerful combination that addresses the complexities of the CSTR system. The fractional-order nature of the FOPID controller allows for superior tuning and robustness, offering enhanced flexibility in adjusting the system’s response characteristics and improving overall control performance. The SCA, known for its effective exploration of the search space through sine and cosine functions, ensures that the controller parameters are optimally selected to enhance the system’s performance by achieving an optimal fitness function. To showcase the effectiveness of the proposed SCA-tuned FOPID controller, comparisons were drawn with other optimization techniques designed for the CSTR system. The study presents time-domain characteristics and frequency responses of the proposed controller. The simulation results demonstrated that the SCA-FOPID controller significantly outperforms the other designed controllers, achieving a 54.07% reduction in the integral of time absolute error (ITAE) compared to genetic algorithm (GA), an 18.64% reduction compared to grey wolf optimizer (GWO), and a 34.79% reduction compared to differential evolution (DE). These significant reductions in ITAE underscore the effectiveness of this approach, highlighting the superior performance and robustness of the SCA-tuned FOPID controller in optimizing the CSTR system.
