| Popis: | Background: Local anaesthesia is most commonly used for cataract surgery in adult patients. Different combinations of local anesthetic agents and adjuvants have been used to provide adequate anaesthesia and analgesia. This study assessed the effect of adding 25 µg fentanyl to lidocaine with adrenaline mixture on the onset and duration of anaesthesia in adult patients undergoing cataract surgery under peribulbar anaesthesia. Methods: This was a double blind, randomized controlled study. Adult patients aged 40 years and above with American Society of Anesthesiologists Physical Status Classes 1 and 2 undergoing cataract surgery under peribulbar block (PB) were studied. Sixty-six patients were randomized into two equal groups. Group A had 25 µg fentanyl (0.5 mL) added to 6 mL of 2% lidocaine with adrenaline while Group B had sterile water 0.5 mL added to 6 mL of 2% lidocaine with adrenaline for PB. Onset and duration of lid akinesia, globe akinesia, globe anaesthesia, Numerical Rating Scale (NRS) pain score, time to analgesia request as well as patient and surgeon satisfaction were assessed. Results: The differences in the onset of lid akinesia, globe akinesia, and globe anaesthesia between the two groups were statistically significant (P ≤ 0.001, respectively). The mean duration of globe akinesia and globe anaesthesia was longer in Group A as compared to Group B (P = 0.008 and P = 0.009, respectively). Statistically significant differences in median NRS scores were found at the 4th, 5th, and 6th h (P = 0.001, respectively). The mean duration to analgesia request was 238.1 ± 65.5 min in Group A compared to 207.2 ± 49.1 min in Group B (P = 0.034). Conclusion: The addition of 25 µg fentanyl to 2% lidocaine plus adrenaline mixture improved the quality of peribulbar anaesthesia and is recommended in Nigerian adults scheduled for cataract surgery under peribulbar anaesthesia to improve their surgical experience. |
