Publication Duration of Anesthesia with Dexmedetomidine as Adjuvant to Ropivacaine in Supraclavicular Brachial Plexus Block: An Observational Study(Nepal Medical Association, 2024) Acharya, Samyukta; Thapa, Chitra; Shrestha, Nisha; Hamal, Pawan KumarAbstract Introduction: Supraclavicular brachial plexus block is effective for upper limb surgeries, with ropivacaine offering prolonged action. Adding dexmedetomidine as an adjuvant may enhance block duration and quality. This study aimed to evaluate the mean duration of anesthesia with dexmedetomidine as an adjuvant to ropivacaine in supraclavicular brachial plexus blocks. Methods: A observational cross-section study was conducted among patients undergoing supraclavicular brachial plexus block for elective upper limb surgery in a tertiary care center. The block was performed using ultrasound-guided, single-injection technique with 0.25% ropivacaine and 0.5 µg/kg dexmedetomidine. Sensory and motor block durations, along with analgesia, were assessed using standardized scales. A convenience sampling method was used. The point estimate was calculated at a 95% Confidence Interval. An ethical approval was taken from Institutional review Committee (Reference number: 026-077/078). Results: The mean duration of anesthesia was 592.42±137.73 minutes (548.62-636.21, 95% Confidence Interval). Sensory and motor block durations were 553.95±138.54 and 555.42±156.24 minutes, respectively, with median onset times of 15 (IQR: 5-22.5) and 24 (IQR: 17-30) minutes. Conclusions: The mean duration of anesthesia with dexmedetomidine as an adjuvant to ropivacaine in supraclavicular brachial plexus blocks was similar to other studies showing prolonged duration and accelerated sensory and motor block.Publication Postoperative Sore Throat among Patients Following General Anesthesia with Endotracheal Intubation in a Tertiary Care Centre(Nepal Medical Association, 2024) Gauchan, Sabin; Thapa, Chitra; Yadav, Rajiv; Bhandari, SabinAbstract Introduction: Postoperative sore throat is the second most common minor adverse event after general anaesthesia with endotracheal intubation. It is an uncomfortable and stressful sequel of tracheal intubation. The incidence of postoperative sore throat varies across different studies and type of anesthesia technique used. The aim of the study was to find out the prevalence of postoperative sore throat following general anaesthesia with endotracheal intubation in a tertiary care centre. Methods: A descriptive cross-sectional study was conducted among the patients who underwent surgery under general anaesthesia with endotracheal intubation from 1 December 2022 to 31 October 2023 after receiving ethical approval from the Institutional Review Committee. The anaesthesia technique was standardized in all the patients. A convenience sampling method was used. The point estimate was calculated at a 95% Confidence Interval. Results: Among 200 patients, postoperative sore throat was seen in 86 (43%) (36.14-49.86, 95% Confidence Interval) patients. The maximum reported time of sore throat was at a fourth postoperative hour 80 (93.02%). Conclusions: The prevalence of postoperative sore throat among patients undergoing surgery under general anaesthesia with endotracheal intubation was similar to the studies conducted in similar settings.
