RESUMO

Various studies have described the use of Dexmedetomidine with local anaesthetic drugs in caudal blocks for the management of postoperative pain in children. This study was designed to determine the analgesic effect of caudal Dexmedetomidine with Ropivacaine in paediatric genitourinary infraumbilical surgeries. Postoperative analgesic effects of caudal Ropivacaine with or without Dexmedetomidine in paediatric genitourinary infraumbilical were evaluated. This study was a prospective, interventional, comparative study conducted after ethical approval from the institute. Informed expressed consent was taken from each patient's guardians. The sample size was calculated to be 31 in each group. The two groups were randomly assigned and the intervention involved caudal epidural injection with either Ropivacaine combined with Dexmedetomidine or Ropivacaine with Normal Saline. Children receiving Ropivacaine with Dexmedetomidine had a significantly prolonged duration of analgesia compared to those receiving Ropivacaine alone (840.35 ± 149.97 vs. 412.90 ± 93.46 min, P < 0.001). Postoperative rFLACC scores were consistently lower in the Dexmedetomidine group, indicating better pain control (P < 0.05 at 6, 12, and 24 h). Total analgesic consumption was lower in the Dexmedetomidine group (500.67 ± 212.92 vs. 741.75 ± 268.06 mg, P < 0.01). No significant differences in adverse effects were observed between the groups. The addition of Dexmedetomidine to Ropivacaine in caudal epidural significantly prolongs analgesia, improves pain control, and reduces analgesic consumption in paediatric genitourinary infraumbilical surgeries.

RESUMO

BACKGROUND: Urinary bladder cancer is more common in geriatric population. Transurethral resection of bladder tumor remains the mainstay of treatment. It is usually performed under subarachnoid block. However, obturator nerve is spared in subarachnoid block that can produce adductor jerk, which is associated with bladder injury, rupture, incomplete resection of tumor and hematoma. To overcome this jerk, selective obturator nerve block is commonly performed. Thus, we conducted this study to compare the efficacy of ultrasound and nerve stimulator-guided techniques for obturator nerve block. METHODS: This is a prospective, comparative study conducted at a tertiary care hospital in Nepal. Sixty patients, scheduled to undergo Transurethral Resection of Bladder Tumor for lateral and posterolateral wall bladder cancer under subarachnoid block were enrolled and divided into two group having thirty patients in each groups. Group I received 15 ml of 0.25% Bupivacaine to block obturator nerve by using peripheral nerve stimulator. Group II received the same amount of Bupivacaine to block obturator nerve under ultrasound guidance. We evaluated the success of the block, ease of the procedure and complications. RESULTS: The adductor reflex was present in 23.33% of cases with nerve stimulator guided obturator nerve block, whereas, it was16.66% in ultrasound guided technique (p=0.75). The success rate of obturator nerve block was 76.66% in nerve stimulator guided technique, whereas 83.33% in ultrasound guided technique (p= 0.21). 83.33% of obturator nerve block was found to be easy in nerve stimulator guided technique, whereas 66.66 % in ultrasound guided technique (p = 0.14). There were no major complications noted. CONCLUSIONS: The findings of this study conclude that both ultrasound and nerve stimulator guided techniques equally abolished the adductor reflexes. Both techniques are easy to perform and safe.

RESUMO

Subarachnoid block is a safe and effective regional anesthesia technique. It is usually carried out in sitting or lateral position but it can also be performed in prone position. Here we report two cases of flame burn over bilateral gluteal region extending to the posterior and lateral aspect of both thighs, who were planned for debridement and split skin grafting. Both patients had difficulty in siting and lying on either side of lateral position. We had administered subarachnoid block in prone position taking into consideration of patient's comfort and the nature of the procedure. Both patients remained hemodynamically stable throughout the procedure and their post-operative periods were uneventful. Keywords: Burn; prone position; subarachnoid block.
