A Comparative Study of Effects of Adding Dexmedetomidine and Fentanyl as an Adjuvant to Isobaric Levobupivacaine in Lower Segment Cesarean Section: A Prospective Randomized Double-Blind Clinical Study | Chapter 3 | New Frontiers in Medicine and Medical Research Vol. 9

Background: Intrathecal Bupivacaine is the most often used local anaesthetic for lower segment caesarean sections, but researchers are always exploring for new local anaesthetics with better safety profiles for both the mother and the foetus. Many adjuvants, such as fentanyl, morphine, or tramadol, have been used with intrathecal local anaesthetics in the past to prolong intraoperative anaesthesia and postoperative analgesia. There is no literature on the use of dexmedetomidine as an adjuvant with isobaric levobupivacaine. As a result, we wanted to see how dexmedetomidine and fentanyl performed in lower segment caesarean sections when paired with 0.5 percent isobaric intrathecal levobupivacaine in spinal anaesthesia.

Methodology: Following clearance by the institutional ethical committee and informed written agreement, patients were divided into three equal groups: Group L will get 2.5 ml of 0.5 percent isobaric levobupivacaine, 5 g dexmedetomidine, and 25 g fentanyl intrathecally; Group LD will receive 2.5 ml of 0.5 percent isobaric levobupivacaine and 5 g dexmedetomidine intrathecally; and Group LF will receive 2.5 ml of 0.5 percent isobaric levobupivac The primary goal was the length of sensory and motor blockage from the time medications were administered intrathecally. For statistical analysis, the chi-square test or Fischer's exact test, as well as One-way ANOVA or the Kruskal Wallis test, were utilised. A P value of less than 0.05 was used to determine statistical significance.

The sensory and motor blockage lasted significantly longer in the LD group (P0.001) than in the LF or L groups. Sensory and motor blockage occurred earlier in the LF group than in the LD and L groups (P 0.001). The LD group took longer than the LF and L groups to reach initial rescue analgesia (P 0.001).

Conclusion: Intrathecal dexmedetomidine produced longer blockade and postoperative analgesia than fentanyl when used as an adjuvant to 0.5 percent isobaric levobupivacaine in elective caesarean section.

Greening Regional Airports: A Vision for Carbon Neutral Infrastructure | Chapter 12 | Contemporary Perspective on Science, Technology and Research Vol. 3

 This study provides an overview of the energy demand of a regional airport, divided into individual time horizons. The electrification of aircraft systems raises the question of whether airports will be among the largest electricity consumers in our infrastructure in the future. Sustainability and especially emission reductions are significant challenges for airports that are currently being addressed. The Clean Sky 2 project GENESIS addresses the environmental sustainability of hybrid-electric 50-passenger aircraft systems in a life cycle perspective to support the development of a technology roadmap for the transition to sustainable and competitive electric aircraft systems. This article originates from the GENESIS research and describes various options for ground power supply at a regional airport. Potential solutions for airport infrastructure with a short (2030), medium (2040), and long (2050) time horizon are proposed. In addition to the environmental and conservation benefi...

Study on Processing Method Influences the Effect of Cassava (Manihot esculenta) Consumption on Blood Lipid Profile in Rats | Chapter 8 | Current Research and Development in Chemistry Vol.1

Cassava is consumed in many tropical countries and is fast becoming the major raw material of many diets, especially in the bakery, brewery and pharmaceutical industries. In a study to determine the effects of various formulations of Cassava feeds on blood lipid profile in rats. Forty adult Wistar rats weighing between 120 and 150 g were divided into 4 groups of 10 rats each. The rats were acclimatized for one week; fed with different formulations of Cassava feeds adlibitum, after which the rats were allotted into groups. Group 1 was fed on Garri; group 2 on Cassava flour; group 3 on Tapioca, and the control group (group 4) on normal chow. After 4 weeks, each animal was anaesthetized by exposure to chloroform vapour and blood samples collected by cardiac puncture. Group 1 diet (Garri) significantly increased HDL-cholesterol (HDL-C) concentration and significantly decreased LDL-cholesterol (LDL-C) concentration (p<0.05) compared with the control group. In Group 2 (Cassava flour), t...

Ethnopharmacological Survey among Traditional Medicine Practitioners in Abidjan (Côte d'Ivoire) for the Management of Pathologies such as Malaria, ENT Diseases, Diarrhea, Typhoid Fever and Anemia | Chapter 05 | New Horizons in Medicine and Medical Research Vol. 8

 Traditional Medicine Practitioners (TMPs) of Côte d'Ivoire are familiar with the therapeutic herbs. Medicinal plants have been shown to be useful in the treatment of common diseases such as malaria (KROA, 2004) and diabetes (N'GUESSAN et al, 2013) in several studies and scientific study. In the Abidjan District, the current policy is to integrate traditional medicine and pharmacopoeia into the national health system in order to improve population health coverage, particularly in the management of commonly encountered diseases such as malaria, ENT diseases, diarrhoea, typhoid fever, and anaemia. This research aims to increase the use of traditional medicine and pharmacopoeia in the national health system. Over the course of three months, fifty (50) PMTs in the District of Abidjan participated in this study. Plant therapists accounted for 30 of the 50 PMTs polled at the end of the study, or 60%. Traditional medicine centres use 61 types of medicinal plants from 36 famili...
