Background: Knee arthroscopy is a common orthopedic procedure done worldwide. Despite its minimally invasive nature compared to the traditional knee surgery, post-arthroscopic pain may be severe, and the patients generally require a significant amount of opioid-based analgesics after such procedures. Aim: The objective of present study was to compare the block of femoral nerve at adductor canal using ropivacaine with additives like Fentanyl with regard to longevity and density of the block in comparison to plain ropivacaine. Methods: Patients of either sex in the age group of 18-75 years, having body mass index (BMI) of 20-35 kg/m2 and belonging to ASA (I & II), who were scheduled to undergo elective knee arthroscopic surgeries were observed in this study. On the evening before surgery, the visual analogue scale (VAS) Scoring was explained to all patients. All the included patients were categorized into two groups viz. GROUP A: Received 20ml of 0.2% Ropivacaine + 2ml of Normal Saline (Total 22ml), GROUP B: Receiving 20ml of 0.2% Ropivacaine + Fentanyl 1mcg/kg diluted in 2ml of Normal Saline (Total 22ml). Results: Sedation score was assessed by using Ramsay Sedation Score (RSS). There was no significant difference in demographic profile of the patients among various groups. Difference in the duration of analgesia was statistically significant among the two groups with longest duration in Group B (7.6+1.20 hours) and was least in Group A (4.3+1.70 hours) (p value <0.01). Total consumption of analgesia (Injection Tramadol 1mg/kg, IV) over a period of 24 hours in Group A was 200+28.76mg and in it Group B it was 108.9+30.64mg. Total quantity of rescue analgesia consumed was more in Group A as compared to Group B among the two study groups (P value <0.001).Incidences of side effects in the subjects were insignificant and only few side effects were noted like, 3.4% of patients in Group A had nausea. 3.2% patients in Group B had vomiting. Bradycardia was noted in 3.4% ...
