The effects of surface morphology, defects, texture and energy on carbon steel corrosion are elucidated along with relevant characterization methods.

Emergence delirium is a common problem in children recovering from general anaesthesia. We performed a study comparing emergence characteristics in 100 patients who were randomly allocated to receive either 0.3 lg.kg À1 dexmedetomidine, 1 mg.kg À1 propofol or saline 0.9% and undergoing infra-umbilical surgery. The Pediatric Anesthesia Emergence Delirium scale was used to grade emergence delirium. Emergence delirium occurred in 9.4% of children in the dexmedetomidine group compared with 13.9% in the propofol group and 40.6% in the control group (p = 0.004). In the dexmedetomidine group, sedation occurred in 62.5% of children at 10 min after transfer to the recovery area, compared with 44.4% in the propofol group and 12.5% in the control group (p = 0.010). We conclude that dexmedetomidine significantly reduced the incidence of emergence delirium but this was at the expense of a greater incidence of sedation in the recovery period.

Purpose: To describe the prevalence, characteristics including risk factors, and pattern of severe ROP from eastern Madhya Pradesh region of India. Methods: In this 5-year retrospective study, Baseline characteristics, systemic risk factors, and findings of ROP screening were noted. Factors associated with severe ROP including aggressive posterior ROP (APROP), stage IV and V ROP were analyzed. Statistical analysis was done using SPSS version 20. Results: Of 763 babies screened, 30% were diagnosed to have ROP. Prevalence of severe ROP was 14.2% (109) of which 60 (55.5%) were classic and 30 (27.7%) were APROP. Eighteen (16.6%) were diagnosed as advanced ROP (stage IV and V). Mean gestational age (GA) and birth weight (BW) for severe ROP were 31.05 weeks and 1.34 kg, respectively which were inversely associated with severe ROP. But a significant 10% of severe ROP were seen in late preterm babies, >34 weeks. Low GA and respiratory distress syndrome (RDS) were significant risk factors for APROP. Most important factor for stage IV and V ROP was late presentation for screening. Conclusion: The study found a high prevalence of severe ROP including APROP. Almost 7% severe ROP cases were outside screening guidelines of NNF. Late presentation for screening is the most important factor associated with ROP related blindness.

Background:The cardiopulmonary resuscitation (CPR) in prone position has been dealt with in 2010 American Heart Association (AHA) guidelines but have not been reviewed in 2015 guidelines. The guidelines for patients presenting with cardiac arrest under general anesthesia in lateral decubitus position and regarding resuscitation in confined spaces like airplanes are also not available in AHA guidelines. This article is an attempt to highlight the techniques adopted for resuscitation in these unusual situations.Aims:This study aims to find out the methodology and efficacy in nonconventional CPR approaches such as CPR in prone, CPR in lateral position, and CPR in confined spaces.Methods:We conducted a literature search using MeSH search strings such as CPR + Prone position, CPR + lateral Position, and CPR + confined spaces.Results:No randomized controlled trials are available. The literature search gives a handful of case reports, some simulation- and manikin-based studies but none can qualify for class I evidence. The successful outcome of CPR performed in prone position has shown compressions delivered on the thoracic spine with the same rate and force as they were delivered during supine position. A hard surface is required under the patient to provide uniform force and sternal counter pressure. Two rescuer technique for providing successful chest compression in lateral position has been documented in the few case reports published. Over the head CPR and straddle (STR), CPR has been utilized for CPR in confined spaces. Ventilation in operating rooms was taken care by an advanced airway in situ.Conclusion:A large number of studies of high quality are required to be conducted to determine the efficacy of CPR in such positions.

Introduction: Severe anaemia is a leading cause of paediatric morbidity, hospitalization, and mortality and it is very important co morbidity in children with severe acute malnutrition. Severe Acute Malnutrition (SAM) with anaemia has been shown to have 2.62 times higher mortality as compared to SAM with no anaemia. So this study was done to evaluate this co-morbidity further. The aim of present study was to determine the prevalence and type of anaemia and to evaluate the possible aetiologies of anaemia in severe acute malnourished (SAM) children.Material and Methods: In tertiary care hospital a cross sectional study was conducted over a period of 8 month with 100 cases of SAM children and 101 cases of normal children. In both cases disorders of primary haematological problem were excluded. Auto analysers were used to measure blood counts. Blood smear was analysed by pathology consultant of institute and recorded for all patients with anaemia. Grade of anaemia and morphologic type of anaemia was analysed. Data were entered in Excel spreadsheets and analysed using SPSS 20.0.Results: Patient with SAM 42% had moderate anaemia and 19% had severe anaemia in contrast 41.6% and 16.8% in NON SAM child respectively. Predominant morphologic type in SAM patient was macrocytic anaemia (33%), while in controls microcytic anaemia (40.6%) was more prevalent.Conclusion: There was a high prevalence of anaemia in SAM children. Major morphologic type in SAM children was macrocytic anaemia which may indirectly show vitamin B12 or folic acid deficiency in these children.

Accumulated corrosion products from two different shipwrecks which had lain on the seabed (2.5 km depth) for 73 years were systematically analysed by three‐dimensional imaging at high resolution using X‐ray micro‐computed tomography. Complementary surface and chemical characterization experiments were conducted to identify the morphological structure of the corrosion products. Goethite was observed as the main corrosion phase found in both the wreck's corrosion products. However, other corrosion products such as silica, lepidocrocite, maghemite, magnetite, benyacarite, jarosite and amorphous materials were noticed using Fourier transform infrared spectroscopy, Raman spectroscopy and X‐ray diffraction. In addition, mineralized microbial structures were also observed as significant constituents of the corrosion products. However, there were significant differences between samples from the two shipwrecks including porosity, distribution and volume percent of the corrosion products components. The mechanism of different corrosion products formation was proposed and discussed in detail.

Background: To identify the determinants of mortality in neonates admitted in sncu of tertiary care hospital with respiratory distress. Neonatal intensive care unit in a tertiary level care hospital in central India. Study Design was a prospective observational study. Neonates admitted with respiratory distress over a period of 8 months. Methods: Neonates with respiratory distress i.e. respiratory rate >60/min, chest retraction, grunting, central cyanosis, were included in the study. Surgical problems causing respiratory distress i.e., congenital malformations affecting respiratory tract and congenital heart disease were excluded from the study. All the cases were divided in two groups based on outcome with good outcome defined as those babies who were discharged and poor outcome defined as those babies who expired during the treatment and analyzed. Results: On analysis, Antenatal history of per vaginal bleed, meconium stained liquor, prolonged rupture of membrane, VLBW, prematurity, pre-ductal SpO 2 , shock, apneic attacks, positive sepsis screen were found to be significantly associated with death. Conclusions: India in recent times has made huge improvement in neonatal care with establishing special care new born units. But, still the neonatal mortality rate is in higher range and needs further intense approach to reduce it. The antenatal and neonatal factors discussed above can be used as referral criteria for early referral of a new born with respiratory distress to a tertiary level new born unit for further management. The early identification and referral of a neonate with above risk factors may help in reducing the associated mortality and hence will reduce neonatal mortality.

Carbon steel is a preferred construction material in many industrial and domestic applications, including oil and gas pipelines, where corrosion mitigation using film-forming corrosion inhibitor formulations is a widely accepted method. This review identifies surface analytical techniques that are considered suitable for analysis of thin films at metallic substrates, but are yet to be applied to analysis of carbon steel surfaces in corrosive media or treated with corrosion inhibitors. The reviewed methods include time of flight-secondary ion mass spectrometry, X-ray absorption spectroscopy methods, particle-induced X-ray emission, Rutherford backscatter spectroscopy, Auger electron spectroscopy, electron probe microanalysis, near-edge X-ray absorption fine structure spectroscopy, X-ray photoemission electron microscopy, low-energy electron diffraction, small-angle neutron scattering and neutron reflectometry, and conversion electron Moessbauer spectrometry. Advantages and limitations of the analytical methods in thin-film surface investigations are discussed. Technical parameters of nominated analytical methods are provided to assist in the selection of suitable methods for analysis of metallic substrates deposited with surface films. The challenges associated with the applications of the emerging analytical methods in corrosion science are also addressed.
