The study also investigates the effects of these drugs on postoperative recovery and overall patient well-being. Methods: The study included fifty patients aged 18-60 scheduled for brachial plexus repair between July 2016 and July 2018. Patients were randomly assigned to two sets: Set LP received 1% LCT Propofol, while Set MP was given MCT-LCT Propofol using TCI-pumps. Blood samples for TG level determination were collected before anesthesia induction, after concluding the infusion, 4 hours after stopping infusion and on day 1 post surgery. Results: Both sets showed a significant increase in TG levels above baseline, with a higher increase observed in the LCT Propofol set (P value = 0.014). After 4th hr of infusion, TG levels significantly decreased only in the MCT-LCT Propofol set (P value= 0.001), with levels lower than those in the LCT Propofol set (P value= 0.021). Conclusion: Prolonged infusion of LCT and MCT-LCT Propofol (1%) resulted in elevated TG levels. However, the increase in TG levels was lower with MCT-LCT Propofol. No significant ill effects were observed. https://aacc.tums.ac.ir/index.php/aacc/article/view/1036
