USG Guided Quadaratus Lumburoum Block and Low Dose Spinal Anesthesia in Abdominal Surgeries.

BACKGROUND: The postoperative analgesic efficacy of trans-muscular quadratus lumborum block in abdominal surgeries is well established; however, its intraoperative safety and efficacy as an anesthetic is still being explored. This retrospective case review was conducted to investigate the efficacy and safety of combined quadaratus lumburoum block and low-dose subarachnoid block for anesthesia in complex abdominal operations. METHODS: Perioperative data of 29 patients, who underwent abdominal operations during the period of June/2019 to October/2019 under the combined technique, was analyzed. The primary outcome was intra and postoperative pain scores with the conox as qnox and numeric rating scale respectively at different time points. The secondary outcomes were intraoperative sedation scores with conox as qcon and perioperative dosage of fentanyl, changes in mean arterial pressure and the incidence of adverse events. RESULTS: The mean qnox scores at incision, viscera dissection, closure and before transport to the post anesthesia care unit were between 44.66 and 55.79. The mean numeric rating scale scores before bed on the operation day, at 8 am on the first postoperative day, before bed on the first postoperative day and at 8 am on the second postoperative day were between 3.41 and 3.86. The mean qcon scores during the operations were between 61.31 and 65.82 while it was 85.66 following the stoppage of all sedations. The mean total perioperative consumption of fentanyl was 38.7mcg. The proportion of patients having MAP changes of less than 20% from baseline was 85.72%. The incidence of peri-operative adverse events was low. CONCLUSIONS: For complex abdominal operations, a combination of ultrasound-guided QLB-TM and low dose spinal anesthesia achieves adequate analgesia and is a safe technique.

Anaesthesia for Antenatal Diagnosed Duodenal Atresia with Undiagnosed Persistent Pulmonary Hypertension of Neonate.

Conversion of fetal circulation to adult-type occurs immediately after birth but neonates with problems in the development of pulmonary vasculature are prone to revert back to fetal circulation. This phenomenon is known as flip-flop circulation which may be induced perioperatively and as such anesthesiologist are central to its management. We report a case of term neonate planned for repair of duodenal atresia that despite having no respiratory symptom preoperatively developed severe hypoxemia under anesthesia that was even unresponsive to 100% oxygen. The intraoperative hemodynamics of the neonate was managed along with supportive care successfully. A postoperative echocardiogram confirmed the evidence of persistent pulmonary hypertension of the newborn. Keywords: Duodenal atresia; flip flop circulation; neonates; persistent pulmonary hypertension of newborn.

Clinical Outcome of Cooled Radiofrequency Ablation in Chronic Knee Pain Osteoarthritis: An Initial Experience from Nepal.

BACKGROUND: Cooled Radiofrequency ablation is a newer technique for management of chronic knee pain in osteoarthritis. The aim of the study is to evaluate the clinical outcomes in patients with chronic osteoarthritis in terms of pain scores for first six months of cooled radiofrequency ablation using ultrasound guidance. METHODS: A cross-sectional study with retrospective review of database was evaluated to analyze the change in the Numerical Rating Scale from baseline scores at 1 day, 1 month and 6 months after the Cooled Radiofrequency ablation of genicular nerves around knee in patients with chronic knee osteoarthritis. RESULTS: Median age was 71 years [ 61-73 years (IQR: 25-75)] with more female preponderance. Numerical Rating Scale (Mean ± S.D.) was significantly less at 1 day (1.87 ± 1.22), 1 month (3.03 ± 0.99) and 6 months (3.37 ± 1.098) from baseline values (6.77 ± 1.00). No soreness and numbness were noted. CONCLUSIONS: Cooled Radiofrequency using Ultrasound guidance for management of knee pain in chronic osteoarthritis is promising and reduces Numerical Rating Score significantly from baseline at 1 month and 6 months respectively.
