Comparative Study between Bupivacaine Alone and With Dexamethasone as An Adjuvant in Ultrasound-Guided Popliteal Nerve Block in below Knee Surgeries

Ultrasound Guided Genicular Nerve Block for Knee Arthroscopy. Comparing using Bupivacaine Alone Versus Bupivacaine and Dexmedetomidine for Acute Post Operative Pain Management: A Comparative Controlled Study

“…In this study, hypotension occurred in five patients in two groups. Also, our study disagrees with Eldemrdash AM [10] who reported that there were significance differences between the studied groups regarding post-operative side effect. Two patients in BD2 group developed bradycardia and hypotension, and one developed urine retention compared to none in other groups.…”

“…Our study agrees with Kim WH [8] who reported that p postoperative paracetamol analgesic requirements over 24 h were higher in group B compared to BD1 and BD2 groups (Mean (95% CI): 3.2 (2.9-3.5) doses, 1.9 (1.5-2.3), and 1.6 (1.3-1.9), respectively), p<0.001. Also, our results agree with Esmail MH [10] who reported that showed no significant differences between the two groups (Group B group BF) regarding need to first morphine dose. Also, Hauritz RW [17] who reported that In group A, all the 25 patients (100%) requested their first analgesia through the first 12 hrs postoperative, while in group B 11 patients (44%) requested their first analgesia through the first 12 hrs postoperative and 14 patients (56%) requested their first analgesia through the second 12 hrs postoperatively, with statistically significant difference between the 2 study groups.…”

“…There was no significant difference in the studied groups regarding age, sex, and ASA. Also, Abd Elrahman AA [10] who studied the sedative effect of dexmedetomidine administered by two different routes. Their study was included 100 patients including 50 cases in each group.…”

“…Our results were consistent with Salah D, [14] who reported that the results imply that intrathecal fentanyl may not be necessary in spinal anesthesia with ropivacaine for lower limb surgery if intravenous dexmedetomidine is administered. Also, Esmail MH [10] who reported that the duration of spinal anaesthesia with bupivacaine alone is noninferior to that of bupivacaine plus fentanyl in patients receiving intravenous dexmedetomidine intraoperatively. Their results suggest that intrathecal fentanyl may not be required when intravenous dexmedetomidine is administered.…”
