General anaesthetic and airway management practice for obstetric surgery in England: a prospective, multi-centre observational study

There are no current descriptions of general anaesthesia characteristics for obstetric surgery, despite recent changes to patient baseline characteristics and airway management guidelines. This analysis of data from the direct reporting of awareness in maternity patients' (DREAMY) study of accidental awareness during obstetric anaesthesia aimed to describe practice for obstetric general anaesthesia in England and compare with earlier surveys and best-practice recommendations. Consenting patients who received general anaesthesia for obstetric surgery in 72 hospitals from May 2017 to August 2018 were included. Baseline characteristics, airway management, anaesthetic techniques and major complications were collected. Descriptive analysis, binary logistic regression modelling and comparisons with earlier data were conducted. Data were collected from 3117 procedures, including 2554 (81.9%) caesarean deliveries. Thiopental was the induction drug in 1649 (52.9%) patients, compared with propofol in 1419 (45.5%). Suxamethonium was the neuromuscular blocking drug for tracheal intubation in 2631 (86.1%), compared with rocuronium in 367 (11.8%). Difficult tracheal intubation was reported in 1 in 19 (95%CI 1 in 16-22) and failed intubation in 1 in 312 (95%CI 1 in 169-667). Obese patients were over-represented compared with national baselines and associated with difficult, but not failed intubation. There was more evidence of change in practice for induction drugs (increased use of propofol) than neuromuscular blocking drugs (suxamethonium remains the most popular). There was evidence of improvement in practice, with increased monitoring and reversal of neuromuscular blockade (although this remains suboptimal). Despite a high risk of difficult intubation in this population, videolaryngoscopy was rarely used (1.9%)

Chemical Sciences A comparative study of triglyceride and fatty acid compositions of palm oils from

Triglyceride and fatty acid composition were determined for palm oils from three different oil palm plantations in South-Eastern Nigeria. Each of the plantations belong to slightly different vegetation belts. The red fruits if the Tenera variety exhibited significant variations (P < 0.5) across the locations. Much of the variations occurred in triglycerides with two or more unsaturated fatty acids in their molecules (P00,000 and OLL) with P00 showing greater differences than the others. Most of the constituent unsaturated fatty acids were observed to vary in their concentrations across locations. Both the locations and varietal source appear to affect the mean total unsaturation of the oil samples.

IDENTIFICATION OF 24-ETHYLCHOLESTANES AS MOLECULAR INDICATORS OF VASCULAR PLANTS SOURCE INPUTS IN COASTAL SEDIMENTS FROM NIGER DELTA, NIGERIA

ABSTRACT The identification of ααα-24-ethylcholestane, 2α-methyl-24-ethylcholestane and 3β-Methyl-5α-stigmastane in extracts of sediments from the coastal areas of the Niger Delta of Nigeria was achieved by gas chromatography-mass spectrometry (GC-MS) technique. The concentrations of the 24-ethylcholestanes varied between 0.05 and 1.40 mgkg-1 in the entire study area. The distributions of the 24-ethylcholestanes, which are known to be diagenetic products of plant sterols (phytosterols) in our samples, suggest possible source inputs from vascular plants around the coastal vegetation of the Niger Delta environment

Establishment of Reference Values of CD4 and CD8 Lymphocyte Subsets in Healthy Nigerian Adults▿

A total of 2,570 apparently healthy human immunodeficiency virus-negative adults from the six geopolitical zones in the country were enrolled in our study in 2006. The samples were assayed using the Cyflow technique. Data were analyzed using the Statistical Package for Social Scientists (SPSS). The majority (64%) of the participants had CD4 counts within the range of 501 to 1,000 cells/μl. The reference range for CD4 was 365 to 1,571 cells/μl, while the reference range for CD8 was 145 to 884 cells/μl
