Abstract

Pneumonia is a severe lung infection, chest X-ray (CXR) image preferred to find infection. Real images lost its quality, resolution and other feature due to transmission. So good qualitative datasets are very limited. Quality enhancement in medical images is challenging task for researchers. And quality in clinical diagnosis of any disease in deep learning play a very important role. So, this paper presents an aspect with importance of quality in medical images CXR of a particular dataset and how to enhance and create new images with high quality resolution, that is re-used for classification in deep learning. Super resolution convolutional neural netwok (SRCNN) is deep learning based method, which is used for improving resolution in image. Super resolution means low resolution (LR) images from dataset is to be reconstructed or magnified into high resolution (HR). The objective behind this study is to measure the effect of super resolution with quality index, peak signal-to-noise ratio (PSNR), mean squared error (MSE), and structural similarity index measure (SSIM). This experinment performed on 200 images with 10 batches, each batch has 20 images from Kermany dataset, select LR images and converted into HR with SRCNN. Then we find PSNR value of image is increase upto 2 to 5 DB, and MSE of qood quality images is near to zero and MSE decrease up to 20-25, SSIM value have little variation due to same pattern is found in input and output images. Enhancement means highlight or improve the region of interest of pneumonic images. Main goal of this study is to preapare a modified dataset which is further used for classification.

Abstract

Introduction:Caudal anaesthesia is the most commonly performed regional anaesthesia in children. Opioids are the most commonly used additives to Local Anesthetics. Synthetic Opioid Agonist- Antagonists like Nalbuphine and Buprenorphine provide advantage of prolonging duration and quality of analgesia without risk of respiratory depression.OBJECTIVE OF THE STUDYTo study the effects of caudal nalbuphine or buprenorphine on postoperative analgesia produced by caudal Ropivacaine in children undergoing infraumbilical surgery.Materials and Methods Following Institutional Ethical Committee Clearance 54 ASA grade I and II children, aged 1-10 years scheduled for elective infra umbilical surgeries under General Anaesthesia with Caudal Epidural were randomly allocated using Computer Generated Random Number Tables into 3 groups R (Ropivacaine 0.2% 1ml/kg), RN (0.2% Ropivacaine with0.1mg/kg Nalbuphine) and RB (0.2% Ropivacaine with 3mcg/kg Buprenorphine). The time taken for first analgesic was noted and was compared between the groups.RESULTS A Total of 54 patients were enrolled for the study. Both the nalbuphine and buprenorphine provided good analgesia in the post operative period compared to plain ropivacaine group ( p<0.05) with higher incidence of side effects in group RB. CONCLUSIONAddition of Nalbuphine(0.1mg/kg) to caudal ropivacaine provides comparable duration of analgesia with caudal Buprenorphine and ropivacaine (3mcg/kg)with lesser incidence of side effects. KEYWORDSNalbuphine,  Ropivacaine, Buprenorphine, Caudal Epidural CTRI TRIAL REGISTERATION CTRI/2017/08/009445

Abstract

Background: Caudal anesthesia is the most commonly performed regional anesthesia in children. Nalbuphine and buprenorphine provide the advantage of prolonging the duration and quality of analgesia without the risk of respiratory depression. The study compares the analgesic effects of nalbuphine versus buprenorphine on caudal ropivacaine. Method: Randomized, double-blind study on 54 patients aged 1-10 years scheduled for elective infraumbilical surgeries, randomly assigned to three groups. Group R (n = 17, receive ropivacaine 0.2% 1 ml/kg), group RN (n = 17, receive 0.2% ropivacaine with 0.1 mg/kg nalbuphine), and group RB (n = 17, receive 0.2% ropivacaine with 3 µg/kg buprenorphine). The time taken for the first rescue analgesic, children and infants postoperative pain scale (CHIPPS), sedation scores, motor blockade, and side effects were noted every 30 minutes in the postoperative room. Data were analyzed using students’ unpaired t-test, ANOVA, Yates' and Fisher’s chi-square tests, with α = 0.05 and 95% confidence intervals (CI). Result: Time to rescue analgesia was 15.54 ± 7.74 hours in RN, 17.96  ±  5.56 hours in RB, and 11.25  ± 8.85 hours in R group. Most patients had a CHIPPS score of 1 in all 3 groups. Motor blockade was not present in all groups (p = 0.650). All three groups were comparable in sedation scores (2, tranquil and oriented) (p = 0.650). There were no significant difference in the side effects between groups (p = 0.060).     Conclusion: Both nalbuphine and buprenorphine prolong the duration of postoperative analgesia when combined with caudal ropivacaine, compared to solely caudal ropivacaine.
