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.Keywords: Cooled radiofrequency ablation; genicular nerve; numeric rating scale

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

Background: Ultrasound guided peripheral nerve blocks have become increasingly popular in the lower limb orthopaedic and gaining more acceptances in total hip replacement surger­ies too. The main objective of this study was to compare peripheral nerve block and spinal anesthesia for total hip replacement surgeries. Methods: In this retrospective study, total patients that underwent total hip replacement in our institution during specific time period were included for the study. They were divided into spinal and peripheral nerve block groups, and data were collected for the analysis. USG guided lumbar plexus, sacral plexus, superior gluteal nerve block was done and conventional landmark technique was done for spinal group. Mean arterial blood pressure, total fluid con­sumption, total fentanyl consumption, pain scores and incidence of nausea was compared. Results: We included 43 patients for the study in which 23 patients were included in nerve block group, and 20 patients in the spinal group. In compared to spinal group, nerve block group had more stable mean arterial blood pressure (P <0.05), less total fluid consumption (P=.000), lower pain scores and fentanyl consumption (P <0.05), and less incidence of nausea (4% to 20%). Conclusions: Peripheral nerve block can be good alternative to spinal anesthesia for total hip replacement surgeries, with more hemodynamic stability and better pain management along with less opioid and fluid consumption.

With the use of ultrasound, peripheral nerve blocks can be more precise and deposition of local anesthetics under direct vision reduces drug volume and minimizes untoward toxicity. Its extensive use in peri-operative period add a safety measures to reduce procedural complications. Pain in children's are often under recognized and under treated which can lead to emotional, psychological trauma for rest of their life. Peripheral nerve blocks have the advantage of greater overall safety and efficacy for lower abdominal surgeries. An abdominal truncal block technique known as Quadratus Lumborum block has emerged recently with a goal of anesthetizing the thoracolumbar nerves for somatic as well as visceral analgesia of both lower and upper abdomen. A sound knowledge of sensory supply to the genitourinary system is important for the success of regional anesthesia. We report a case of four years old child who was diagnosed as left sided pelvic ureteric junction obstruction and was planned for pyeloplasty where continuous quadratus lumborum block was used as a mode of post operative analgesia which showed a promising result. Antibiotic resistance and lack of newer effective antibiotic against multidrug resistant bacteria like Acinetobacter baumannii is a common problem in intensive care unit. Trimethoprim -Sulfamethoxazole may help in combating this problem.

Entrapment abdominal neuropathy is not a common diagnosis in our context. Chronic Abdominal wall pain is often mistaken for gastritis, gynecological issue, thoracic spinal radiculopathy, rectus sheath hematoma, abdominal muscle injury or psychiatric disorder. Anterior cutaneous nerve entrapment syndrome is one of the frequent causes of abdominal wall pain occurring due to trapped thoracic intercostal nerves between abdominal muscles. History and bedside Carnett’s sign can elicit the diagnosis. Injection of the local anesthetics with steroids in the junction between the rectus sheath and abdominal muscle under ultrasound guidance can provide sustained pain relief. We should consider Anterior cutaneous nerve entrapment syndrome as a differential diagnosis while evaluating the abdominal wall pain.Keywords: ACENE; carnett’s test; chronic abdominal pain; entrapment neuropathy; hydrodissection.
