Publication Prevalence of Caudal Block and Duration of Analgesia of Caudal Dexmedetomidine Adjunct in Pediatric Lower Abdominal Surgery(Nepal Health Research Council, 2024) Baral, Bidur Kumar; Poudel, Puspa Raj; Malla, Sadichhya ShahBackground: Caudal block is a commonly used method of postoperative pain management in children. However, single shot caudal block has shorter duration of analgesia that can be extended by addition of adjuncts like opioids, clonididine, and dexmedetomidine along with local anesthetics. Recently, dexmedetomidine has been used as an adjunct for prolonging the duration of analgesia. This study aimed to find out prevalence of the caudal block and the duration of analgesia with dexmedetomidine adjunct among children undergoing lower abdominal surgeries. Methods: A cross-sectional, observational study was conducted among the children admitted to the tertiary care children hospital of Nepal during the period of six months. Children of age 2 to 7 years, who had undergone lower abdominal surgeries under general anesthesia were enrolled in the study. We observed the prevalence of the caudal block and duration of analgesia of caudal dexmedetomidine with ropivacaine Results: Throughout the study period, 449 children were posted for lower abdominal surgeries. Out of which 226 children (50.03%) received caudal block. Among the caudal block, 51 children (22.56%)) were administered ropivacaine with dexmedetomidine, 45 children (19.91%) received ropivacaine alone, 43 children (19.02%) were given bupivacaine alone, 46 children (20.35%) received a combination of bupivacaine and fentanyl, and 41 children (18.14%) received bupivacaine and dexmedetomidine. Dexmedetomidine with ropivacaine provides 840.35±14.97 minutes of postoperative pain relief. Conclusions: The prevalence of the caudal block was 50.03%, and the combination of Dexmedetomidine with ropivacaine provides longer duration of postoperative analgesia. Keywords: Analgesia; caudal block; children; prevalence.Publication Ultrasound versus Nerve Stimulator Guided Obturator Nerve Block in Patients Undergoing Transurethral Resection of Bladder Tumor(Nepal Health Research Council, 2022) Baral, Bidur Kumar; Poudel, Puspa Raj; Rajbhandari, Mona; Karki, Anuj Jung; Dhakal, Gaurav RajAbstract 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. Keywords: Bladder tumor, obturator nerve block, adductor reflex
